Graphene Based sieve Turns Seawater into Drinking Water


Graphene Based Sieves Makes Seawater Fit For Drinking

It is an unaltered fact that Sea Water is not fit for drinking because of the excess Sodium content in it, but science is developing at a very fast pace and in this 21st century the stalwarts of science and technology have innovated a new technique through which they can separate salt from the sea water and will make them fit for drinking. We cannot drink sea water because of the taste, simultaneously it leadsto several other health problems like high blood pressure and many more.

Our planet Earth is known as the blue planet because it has approximately 71% of water out of which only 3 % of the water is non-saline and hence fit for consuming. Due to this situation, there are people in this world who do not get optimum amount of water to drink and there are many who even die due to the scarcity of drinking water. If the researchers can reduce the percentage of unfit water by making it fit to drink, then that would be a very big gift to mankind.

A team of researchers based in UK have developed a sieve based on Graphene that can remove salt from the sea water and will make it fit for drinking. A team from the University of Manchester had confirmed a fact in 2004 that graphene consists of carbon atoms which are layered singly and are organized in a lattice in the form of a hexagone, due to which this tool is sure to provide promising results with the help of extraordinary properties, which includes unusual strength in the tensile and a high conductor of electricity that ensures this as one of the most potent material to grant assured measures in the past.

The scientists have also declared that it is quite difficult to manufacture such single layered Graphene with the existing technologies. The production cost is also very high and that needs to be supported. The deposition of chemical vapor method won’t be much feasible to support the innovation from all ends. Rather, a very onymous scientist has confirmed that oxides that are to be used in the Graphene can be produced only via a simple method of oxidation in the lab.

Though, he orated it to be simple, but the process is lengthy. This is undoubtedly a very big step to abolish the problems cropping up due to scarcity of drinking water, but the underlying measures are such that cannot be averted and for this, the technique of Graphene is still at stake. Manufacturing of single layered Graphene is not much feasible, instead we can replace it that with oxide Graphene, which will give the same result with less cost of production.

Some problematic zones have been discovered when it comes to Graphene of single layer and these uncomfort zones can be avoided if Graphene of oxide are used in its place. So, in this era using of oxides of Graphene will be much suitable to avoid unnecessary expansions.

Google Uses Neural Networks to Translate Without Transcribing

Google Makes Use of the Neural Networks for Translating without Even Transcribing

Google is actively working towards enhancing its translation abilities to a whole new level where it can be helpful and promptest in every manner. Google eagerly wants to help the mankind in communicating with people in different language by translating the speech rather than the text language. Almost all the translation tools focuses on translating the text rather than text and Google understand the amount of good work it can bring with it.

The machine translation will actually work by translating the speech into the text then that text is translated in another language. In case the machine gets any kind of error while recording the speech then it will result in error prone language translation which will fail to serve the purpose which it is intended to do. This is where Google is working at.

The Google Brain

Google has deployed a large number of researchers at the Google Brain where they are making use of the deep learning research facility for better results. Researchers have started making use of the neural networks which can help in skipping transcription while translating any given speech at a faster pace with higher level of accuracy.

Researchers has spent huge amount of time which counts into hundreds of hours in training the system with Spanish to improve its translation skills into the English language. The system present at the Google at first went to analyze the waveform of the Spanish audio in order to learn who he different parts of the language tend to correspond with the words in the written English language. Later on this system was entrusted with the task of translating the speech and its was do so with great accuracy and precision through making use of the neural layers.

The capability of this system

A researcher from the University of Montreal who wasn’t a part of this research has stated that the capability of the Google Brain is mind-blowing. It has the ability to find the patterns of the correspondence between the various waveforms. These waveforms happen to be present in the source language as well as the written text. Over the time where learning phase is initiated The Google Brain has the ability to bring one of the best English translations of the Spanish speech.

The quality of translated of the speech is evaluated using the BLEU which helps in understanding how good machine based translations are when compared to the professional human.

The future application of this system

Google developed system will be of great use for translating the speeches in such languages which is usually done by very few people. It can play a vital role during international disaster relief wherein teams can make use of a robust translation system in order to communicate with people who speak different language. An incident can help in imploring its advantages this system as in 2010’s Haiti earthquake the relief team had a hard time in conversing with the people speaking Haitian Creole.

Triboelectric Nanogenerators Boost Mass Spectrometry Performance

Triboelectric Nanogenerators

Scientists Successfully Boost the Mass Spectrometry Performance by Using Tribolectric Nanogenrators

The most basic problem which surfaces in the entire consumer electronics device is the power consumption. We are actively looking for such kind of power source which doesn’t put a hole in our pocket and helps in getting performance out of the device. Researchers have come with a solution by developing the triboelectric nanogenerators (TENG) which will help in converting the mechanical energy from the environment to electricity. And this electricity will be more than enough to power some of the small devices which include the sensors and consumer electronics products.

The team behind this remarkable technology

This technology has been developed by researchers at the Georgia Institute of Technology which can bring a trend of replacing the traditional power supplies with the TENG device for charging. Though in this case the TENG devices will be used of charging the molecules in the spectrometers and the research has shown that it take the sensitivity of it to an unimaginable level which is good in every way. Scientists have conducted few experiments on the smaller samples in order to understand the full extent of the applications of the TENG technology.

During their research it was found that this technology requires further study the TENG offers unique aspects in its output which has a remarkable high voltage as well as controlled current. This means that the TENG can help in making incredible improvements in the ionization process and later on increased voltage speed can be easily applied to the instrument without even damaging it. This research has already been published in the journal Nature Nanotechnology and quite incidentally this research has been supported by the Natural Science Foundation as well as Department of Energy and NASA astrology Program. Researchers has been modest about their astonishing technological discovery based on the nanogenerators by stating that it is quite new and it is being used in a very controlled manner in order to charge the molecules.

The remarkable finding of the research

Researchers have made use of this technology in the electrospray ionization and plasma discharge ionization wherein they have been able to generate singular polarity as well as alternating polarity of ion pulses. Researchers have successfully measured the voltage level present in the mass spec ionizer to be between the 6000 to 8000 volts. It is a great achievement given the fact that the standard iconizer presently in use can only operate at less than 1500 volts.

The future application of the TENG technology

Researchers have retrofitted the tech technology to existing mass spectrometers and this has been done in the lab with great success. Their research has already been published in some of the journals and researchers are hopeful that more number of people starting making use of the TENG technology in not just the mass spectrometry but even other areas. This nanogenerators based technology will certainly help in getting more power for our daily use devices without spending huge amount of time and money.

Why Your Smartphone's Fingerprint Scanner is not as Secure as You Might Think

Master Fingerprint – Less Secure 

Researchers who had developed `master fingerprints’ with the capability of tricking the sensors, are of the belief that smartphone fingerprint scanners tend to be less secure then led to believe. They were capable of bypassing fingerprint readers that had been utilised in unlocking phones, log-in to apps and in making payments, utilising fake fingerprints developed by using patterns located across several real prints.

 This discovery from New York University and Michigan State University gave rise to query regarding security of the popular utilised technology. The researchers were capable of creating a set of `master prints which could trick a scanner up to 65% of the time.

Fingerprint scanners are considered to be more secured than depending on passcodes in unlocking smartphones. According to Apple the Touch ID scanner utilised on the iPhone tends to have only a one in 50,000 chance of matching with somebody’s finger.

Though the researcher state that they had tested only their discoveries in computer simulation instead of real smartphones, they cautioned that the technology creating artificial physical fingerprints had been refining quickly.

Adequate Resemblance Between Various Prints

Since in present days the fingerprint readers on smartphones seem to be comparatively small, they usually tend to scan various areas of a fingerprint making sure that just one press of a finger or thumb could effectively trigger the sensor.

 Since several users tend to register numerous fingerprints on a device and there are often dozens of various incomplete prints registered on a phone, only one of these incomplete scans could be a match for the sensor in unlocking a phone. According to Nasir Memom of NYU, one of the authors of the study that had been published in IEEE Transactions on Information Forensics &Security had commented that there is a greater opportunity of falsely matching a partial print than a full one and most devices tend to depend only on partials for the purpose of identification.

In spite of the human fingerprints being comparatively exclusive, researchers have stated that they had discovered adequate resemblances between various prints in creating synthetic master prints which could effectively replicate several fingerprints of the users.

Hosted Other Authentication Systems 

Since the phones seem to typically permit several attempts before deactivating the fingerprint scanner and needs a passcode, Mr. Memon had stated that one could create a glove with five different fingerprints which would get into almost half of iPhone before the five attempts permitted, tend to expire.

Irrespective of the well-known trust in fingerprint scanners, some of the phone manufacturers had hosted other authentication systems. The new Galaxy S8 phone of Samsung is said to have an iris scanner together with facial recognition though the latter is shown to have been fooled by images. Moreover, smartphone passcodes have also portrayed to be susceptible to cracking.

There seems to be a one in 10,000 chance of guessing a four-figure passcode though researchers from Newcastle University have shown that the motion sensors in a phone could disclose the numeric codes by identifying how a phone tends to move when certain areas of the screen are pressed.

Japanese researchers had earlier cautioned that posing with peace signs in images could be adequate for hackers in copying your fingerprints and then unlock a fingerprint secured phone.

Researchers Print Promising Two-Dimensional Transistors


Researchers just printed two dimensional transistors successfully

If you are wondering what transistors then please note it is essentially a semiconductor devices which helping amplifying and switching the electronic signals or electric power as a whole. It plays a vital in almost all the electronics products which are available in the market and without it you can’t even think of devices performing the way they are. Some of the researchers from AMBER and Trinity College in Dublin have successfully created printed transistors that consist of only two dimensional nanomaterials. The best thing about this innovation is that no one has done it before and the 2d materials used in comes loaded promising electronic properties which is extremely low cost in nature.
This research does have some of the incredible application potential which can’t be explained to its fullest. For example in future the food packaging industry can make use of it bring a digital countdown which will alert the users about the health of the food and placing it on wine bottle can help in showing whether wine is kept at the optimum temperature or not. Their finding has already been published in the Science magazine April issue.


The team behind this technology

Using the standard printing technique of combining the grapheme nanosheets which includes the electrodes with two other nanomaterials namely boron nitride and tungsten diselenide. The two most important parts of the transistors is called the channel and separator and researchers has been able to print it on a nanosheet thereby coming up with a working transistor.

The team of researchers consisted of Trinity College professors namely Jonathan Coleman and Georg Duesberg. Coleman has shed light on the future possibility of creating or combining together highly complex device by conducting, semiconducting as well as insulating the 2D nanomaterials. But during their research they simply focused on printing the transistors which can work as electric switches into the modern computing with ease and grace. 

New method indulge in testing without even touching

Earlier the chemical vapor deposition were used to develop the two dimensional transistors. Using this particular the transistors were great at performance but the method itself was quite expensive.

While the printable electronics brings a new way of printing components which are mostly based on the carbon based molecules at extremely low cost and get an amazing performance out of it at the same time. It is worth noting that carbon based molecules does have its own share instability and performance limitations but it is still better than the chemical vapor deposition.

A single nanosheet can do much better

Researchers has made use of many different nanosheets of completely varying size in order to get best combination available for the printing their transistors. When the printing process was initiated researchers simply deposited the nanosheets over one another in random fashion and it was found that the conductivity present within the nanosheets was just good for the job.

So the next job for the researchers is to come with a single nanosheet which will help in printing such 2D structures which offers better performance than the current one.

Google Chrome's most frustrating feature is BACK

Google Chrome is bringing back the most annoying feature

There is a very annoying feature built right into the Google Chrome which uses to leave users frustrated beyond words. Just last year Google finally said goodbye to its annoying feature which allowed users to make use of the backspace key as a smart function to return on previous page.
The major reason why Google went ahead removed this feature from the Google Chrome is that users has complained that they happen to lose data whenever they hit backspace while filling out the online forms. When a user made use of the backspace in order to delete the text in the form then they were simply thrown back to the previous webpage they had visited. This feature was put to its end with the arrival of Google Chrome version 52.

A good thought from Google

At that point of time this feature was seen a major ‘low point’ in the Chrome experience. One of the Google employee even stated that removing that feature brought a major change in the people habit which is a good thing but given the fact the data loss is major issue in today’s time the idea of dropping that feature is well conceived.

Extension to get back to old habits

However people who loved that feature which allowed them to get back without taking the pointer to the back arrow does have some good news. A new Google Chrome extension has come into the play which allows users re-enable this extinct feature on their feature with ease and grace. From now users will get the same old pleasure of hitting the backspace key to back to the previous webpage with this simple browser add-on.

Google is behind the Chrome extension

If you are thinking that some smart user has made this extension in order to bring back the feature to millions of users. Then you will be surprise to know that it is Google who had rolled out the free Chrome extension just week ago on the WebStore. Users are simply required to download the add-on, install it and they are set to visit previous webpages with the stroke of the backspace. Google has titled this extension as ‘Go back With Backspace’ which can be easily found in the Chrome Store.

After installing the extension hitting upon the backspace on the keyboard will bring back the previous webpage. In case you are wondering you will lose your data while filling up the forms online then simply click on the extension icon in the Google Chrome and give a tap on the ‘Disable On This Page’. There is plenty more you can tinker around by simply giving a on the small gear icon for more settings options.

Google has spent some serious time with this extension to make it smarter and innovative accessory for online web browsing experience. Now this extension comes with the default functionality of being disabled for java and flash applets as well as PDFs and the common chat tools.

Microsoft confirms Windows 10 Creators Update

Windows 10 Creators Update to rollout from April 11

Microsoft is set to start the roll out of the Windows 10 Creators Update to the users globally from April 11. The launch of the rollout start date was confirmed by the Microsoft officials though a blog post on March 29. The Anniversary Update started rolling out in August last year while Microsoft has to delay the launch of the Creators Update by several months. This update will be known as 1703 though it was due to hit the systems globally in early but dues to this reason it is coming so late.
The game of changing ‘name’

Windows 10 Updates are extremely confusing for the common users to follow around but one thing has been consistent so far which is the naming of the updates. Now, Microsoft has revealed that the expected roll out for the masses in beginning of the April is simply named as ‘15063’. This shows that this build number will not be named RTM which is short for ‘release to mainstream’).

Features of the Creators Update

Microsoft has been indulging the performing huge testing on the Creators which effectively is the successor of the Windows 10 Anniversary Update for quite some time. Creators Update brings a number of consumer focused features to bring a marvellous computing experience to the consumers. This includes a new Game Mode, Windows Mixed Reality support, Beam game streaming along with a new robust eBook & tab management capabilities for the Edge browser. The iconic Paint application will also undergo a major change a new variant in form 3D paint will debut on the Windows. Microsoft is not doing away with the 2D Paint application as both of them will work in unison on the operating system.

Update on the final roll out of the Creators Update

Microsoft yet again failed to abide by its promise and it has been confirmed that the new roll out date for the Creators Update will be set at April 25. Microsoft officials have given no update regarding the launch of the Creator Update on the Cloud version. It should be noted that the Cloud version of the update is designed specifically to run the Windows Store apps and in later stage it will become upgradable to the Windows 10 Pro version.

Broader availability of the Surface device

The Microsoft gives major information where it has stated that the availability of the Surface range of devices will be boosted on global scale. Last October Microsoft has launched three major variant of the Surface Boko which includes the Surface Book with Performance base, Surface Studio and Surface Dial.

Microsoft will be making Surface Book with Performance available in countries namely Austria, Hon Kong, Japan, Denmark, China, Finland, Norway, France and Netherlands as well as UK, Switzerland and Sweden on April 20. Surface Studio as well as Surface Dial will be available for purchase only in Australia, New Zealand and Canada from 20. All these devices are open for pre-order in these selected countries.

Controlling Turtle Motion with Human Thought

Turtle Motion
About nine years ago we saw the flick which showed humans controlling the body of an alien. Today we have that technology though it is in the initial but has huge potential to grow by leap and bounds in the upcoming years. Leaving the realm of science fiction aside scientists has long been working on developing a system called ‘brain computer interfaces’ or BCI. This particular technology is designed to allow humans to read and use the thought in order to control the machines and one of its prime examples are the humanoid robots.

Now the researchers at Korea Advanced Institute of Science and Technology (KAIST) had successfully developed a highly sophisticated human turtle interaction system. This system allows the signals emerging from the human brain to produce desirable effect on the movement of the turtle.

How this technology works?

If you are wondering how human are able to control the turtle movements simply with their thought then here is complete process. Human operator has to wear a head mounted display which is commonly refereed as HMD. HMD IS combined with the BCI which helps in immersing the human operator right into the turtle environment. On other hand the turtle in question is equipped with a cyborg system which consists of a camera, Wi-Fi receiver along with a control module as well as a battery. All of this is mounted on the upper shell of the turtle. A black semi-cylinder with a slit is also placed on the shell which helps in forming a true simulation device.

A camera is mounted on the turtle which is received by a human operator. Using these real time video images the human operator has to be deciding where he wants the turtle to move about. Human operator is required to provide all the commands which affects the motion of the turtle using a wearble BCI system which effectively makes use of the electroencephalography (EEG) signals.

Currently the BCI system is designed to take commands only in the three metal states of left, right and idle. Now when the human operator tends to make the choice either left or right that commands happens to activate the turtle simulation device which is connected through a Wi-Fi. This particular process invokes a natural instinct in the turtle to move towards the light and thereby it changes the direction.

Future applications of this technology

This research has clearly demonstrated how the human thought can be utilized in developing animal guiding scheme for turtles. This technology in future can be easily integrated into positioning system and can certainly help in augmented and virtual reality techniques.

On other hand this can be helpful in enabling a wide range of application which might devices form the military reconnaissance and surveillance. But for these to happen it might take another decade to make the technology human proof, robust and highly reliable so that it can distinguish from the raw and concentre commands originating from the human mind.

Google Takes Aim At Update Its Duo Videoconferecing App in Battle with Skype, Messenger and Facetime

Google’s New Video-Calling App – Duo

A new video-calling app known as Duo had been launched by Google as a challenge to Skype and Apple’s Facetime. It tends to work using your mobile phone just like WhatsApp, once the app has been downloaded and logged utilising a Google account. The user can instantly video call any person from their contacts who also tend to have the app.

Though the main focus of Google is on ease, it does have duo features with a provision of differentiating it from its opponents. For instance a feature known as `Knock Knock’, enables the user to see live video of your caller before answering, providing you with a sense of what they could be up to and why they would prefer a chat.

 According to Google this makes video calls seem like an invitation rather than an interruption. Another benefit of the feature is the capability of switching between Wi-Fi and cellular data mechanically without dropping the call. This way you could start your call at home and continue effortlessly while heading out.

The benefit of Duo over FaceTime is that it tends to work on Android as well as iOS while FaceTime only operates on Apple devices. It has also been considered to be simpler than Skype enabling users to start a video call with only a tap.

Cope with Slower Networks

Justin Uberti, principal software engineer at Google had mentioned in a blog post that video calling is the next best thing to being with someone in person but too often it could be a frustrating or complicated experience.

One should not have to worry about whether your call will get connected or if your friend has been using the same kind of device similar to the one you could be using and this could be the reason why almost half of them never tend to made video calls on mobile.

Google has also built Duo to work to cope with slower networks in the background, like a 2G together with end-to-end encryption for the purpose of security. Google had mentioned that it would be offering an audio-only option on its Duo video calls service in order to assist users in communicating utilising poor quality connection and would be adding a feature to allow file sharing in group chats on its Allo messaging app.

In August, the company had launched Google due offering video calls for Android and iOS users, opposing it against Apple’s FaceTime, Microsoft Corp’s video calling app – Skype and Messenger of Facebook Inc.

Google Maps

Google Vice President for Product Management, Mario Queiroz had mentioned in a blog post after he had announced the moves at a Google conference in Sao Paulo that the audio-only calls would be working well on all connections speed and would be data efficient. In reply to responses from users in countries like Brazil,

Google had informed that Android users all over would be in a position of sharing documents as well as other files with friends on Allo in group chats. Moreover he also mentioned that they would have two new features for Google Photos on Android and iOS in order to make backup and sharing much easier on low connectivity.

When strong Wi-Fi connection tends to be available backed up photos would be replaced with high-quality version. Google has also mentioned that it would be adding new location sharing feature in Google Maps to enable users in letting friends and family to be aware of their whereabouts and when they would arrive at their destination. Queiroz had also mentioned that users could stop sharing that information whenever they desire to do so.

Fuzz Fibers Can Take Rockets Heat

 Fuzz Fibers
Rocket engines of latest design have much vigor, and produces heat. Recently, NASA has made a joint effort in order to create some fibers for taking the heat of rockets.

The special fibers are manufactured with silicon carbide, which may be comparable to Velcro. They are able to resist the pressure, which is experienced by materials in many applications of aerospace. Such fibers give enough support to composite materials, which are often applied in the latest rocket engines with a capability of enduring high level of temperature. Ceramic materials, present in these rockets, make use of the fibers for toughening the system. However, at any time, brittleness or cracks may turn up, especially because of oxygen exposure.

Use of nanotubes along with fibers-

The researchers of Rice laboratory have implanted nanowires and tubes into fibers’ surface. The uncovered spots of these fibers have coiled design. They work almost as a hook to add value to Velcro. After making the experiment, the scientists have concluded that it leads to the development of powerful interlocking links with lots of knots of fibers. As a result, a composite has reduced level of cracking risk. Moreover, due to sealing, the chemical structure of fibers is not changed.

Amelia Hart, one of the students of Rice University, has stated that fuzzy fibers could be improved with the application of nanotubes (made of silicon carbide), which are interwoven with one another, while is placed inside composite. It also increases the resistance level and strength to endure intense heat.

A test on compression and friction confirmed about the force, which was essential for moving the nanotubes over one another. This force seemed to be quite higher than what is required for sliding the simple fibers or nanotubes. They could also pull through extreme compression, created with the help of nano-indenter. The indenters prevented breakdown for much extensive period.

The complete work has been explained in detail in one of the journals. It had been started, while Hart had met Meador, one of the researchers of NASA. Presently, Meador is a manager of nanotechnology program, while Hart was engaged in the study, related to carbon nanotubes development.

It had brought about a good partnership, which would increase the possibility of combining her thoughts with the engineer of NASA. A partial conversion of silicon carbides was accomplished. In fact, Hart had applied the skill for growing nanotubes to create fresh composite.

Tests on different fibers-

Hart along with other researchers blended the fiber in iron-based catalyst. After that, they applied a deposition of chemical vapor for inserting carbon nanotube system to a surface. It turned out to be the model of ultimate product. Then, these fibers had been heated under severe temperature.

 It is considered by researchers that the fibers would modify heat and light resistant silicon carbide strand. The later one is able to stay consistent to almost 1,600 C. It gives the scientists a confidence on the success that they would get by integrating nanotubes, made of silicon carbide.

New Electron Microscope Sees More Than an Image

In the field of material science, electron microscope has lots of application as an effective device. It is usually known to all that this tool helps in viewing at an image. However, with the new enhancement done few days ago, this microscope has gained much more power. And it has been confirmed recently by some physicists at Cornell. The overall system is named as Electron Microscope Pixel Array Detector. It produces image along with some important data on the present electrons, which develop that image.

To give a clear idea about the microscope, Professor David Muller has said that it is possible to identify the tilts, polarity, rotations and magnetic or electric fields.

Manufacturer of the new microscope-

CTL department of Cornell University has accredited the innovation of new microscope to a prominent manufacturer, FEI. According to FEI, the design may be commercialized fully on the present year. In a periodical (Microscopy and Microanalysis) in 2016, the researchers have clarified the work in detail.

In another standard microscope, STEM, the researchers have observed that few electrons could be captured with the help of a specimen. The scanning is done from side to side to generate images. There is a detector at the base, and it interprets how the electrons are varying in their intensity.

EMPAD is intended for the replacement of a standard detecting system, and it is designed with specific pixels, which are sensitive to electrons. Every one hundred and fifty microns square are attached to a circuit, which warns signals with enough effectiveness in understanding signals. This technology is comparable to what you may find in contemporary camera. The major intention is the detection of angles or directions, where the electrons come out. Every electron usually does not strike at the same pixel.

Microscope with prompt working ability-

EMPAD has remarkable sensitivity and speed along with extensive intensities, tracked by it. It also detects each of the electrons and beams that contain almost millions of electrons. To explicate the phenomenon, Muller has commented that it is just like the act of capturing image of sunset, which displays surface details and everything about the shadows.

The advancement that has been done to the device is really unique and increases the excitements of scientists. Collection of all electrons that are in scattered condition develops the sensitive feature of the device. Moreover, it is also reduces the risk of damage and any negative effect on the living sample. EMPAD has power to track the frame of image within shortest time, and it identifies several electrons for every pixel and frame. In fact, it is multiple speedier than that of any traditional electron microscope.

Thus, the new microscope has brought a revolution in the domain of science. The scientists are now competent at examining the internal part of the cells. The research process has been backed up by Department of Energy in the United States and Cornell. STEM adaptation has also received support from Kavli center.

Innovative Software Convert Wi Fi Data into Energy Savings

The advancement of technology had begun since the arrival of human kind of Earth’s sphere. From the invention of knifes and spears to the creation of computers and tablets, man has managed to come a long way. It is a known fact that this technological advancement has been exceptionally brilliant in the past two centuries. Every day scientists around the world are striving to create something newer that is not only mind boggling but will also be useful to mankind.

High quality air with reduced energy consumption 

Recently in the University of British Columbia in Canada, a group of dedicated engineers have derived a way by which they could use Wi-Fi to establish number of building residents. By determining the number, they can easily adjust the ventilation through which they would be able to save energy without compromising on the air quality. Stefan Storey who holds a PhD in environmental studies and resource management and masters in mechanical engineering from UBC is leading the project. He remarked that thousands of tablets, laptops, and Smartphone are connected everyday to Wi-Fi through UBC. The Bridge Software incognito calculates the total number of Wi-Fi connected devices in every room. This anonymously calculated number is then passed on to the head building control system of UBC, which then regulates airflow through the buildings, in real time.

Based on this resident count, the control system can manage the airflow, ramping it for a crowded lecture, or bringing it down in other times. Storey collaborated with UBC for testing the effectiveness of this new technology at one of the busiest places, Irving K Barber Learning Centre, which is attended by thousands of staffs and students. It not only resulted in increased occupant comfort and goof air quality but also reduced energy expenditure by five perfect in 12 months.

Increased thermal comfort at a reduced rate 

UBC’s managing director, David Woodson remarked that this system can save over $100,000 in energy costs every year and would also assist the university in reducing greenhouse gas emission. UBC is considering this system to be the future of managing and better handling of energy consumption. The test conducted at the learning centre was highly successful and seeing the results of this ordeal, UBC is all set to install the technology in 8 to 10 more buildings within 5 months. Woodson also stated that this software uses Wi-Fi network, to reduce the disruption and lower the costs while offering thermal comfort and providing good air quality. He also stated that UBC Wi-Fi user’s private information is completely secured and protected as per the rules of Canadian privacy legislation.

Storey believes that this project emphasizes the prospective advantages of using Wi-Fi network to create smart buildings. With the support from UBC he also co founded Sensible Building Science, a company that helps staff entrepreneurs, faculty, alumni and students to lead their way through, from a basic idea to the market. Storey’s patent innovation is being set up at campuses around B.C. UBC is extremely happy about the success of this project and is thus is planning to expand their system to 10 more campuses.

‘Machine Folk’ Music Shows the Creative Side of Artificial Intelligence

Folk music is seen a direct link which connects us to our past and helping in cementing the cultural bond. When it comes to Artificial Intelligence it doesn’t possess any cultural heritage, bond or traditions but can we help Artificial Intelligence in building those attributes which defines the human intelligence at some levels. Over the years AI has grown by leap and bounds as it has been able to defeat the brightest human minds at Chess and even demonstrated breath-taking wordplay skills but can it create music or show us the creative side.

Artificial Intelligence on the rise

Researchers are trying to unlock the creative side of the Artificial Intelligence for quite some time. In 2016 a AI has been able to produce a piece of musical theatre which was premiered in the London. The effort is given towards broadening the boundaries of the creative research through new evolved AI techniques and utilizing the larger collection of the data. The Artificial Intelligence written musical piece has been a result of a thorough analysis of hundreds of other successful musicals.

Some of the prominent Artificial Intelligence project which aims towards bringing art and music out of the AI includes Sony’s Flow Machines, Google’s Magenta project and some projects under the British startup called Judedeck.

During the current study researchers has made use of the state of the art Artificial Intelligence techniques in order to educate Ai about the musical practice in the Celtic folk tradition. Traditional folk music was reduced into the form of music notation using ABC. In this method the music is denoted using the text characters as a rough guide for the musicians. Researchers have been successful in training the Artificial Intelligence for using as many as 23,000 ABC transcription of the folk music. This particular feat of transcription this amount of folk music was made possible with the active contribution of the people on the ‘the session.org’. During recent workshop researchers has asked the folk musician musicians to perform some of the songs composed by the machines.

The culmination of the artificial compositions and the human melodies

This particular Artificial Intelligence is trained to look at a single ABC symbol and predict what will come next and this helps in generating new tunes which appears to be like original compositions due to the use of existing patterns and structures. So far researchers have generated as many as 100,000 new folk tunes using Ai which is a remarkable feat in itself.

The structure of the folk music composed by the AI has two repeated part of similar eight-bar length and they complement each other quite musically. Secondly AI had also shown a great ability of repeating and varying the musical patterns which has always been the key characteristic of the Celtic music. AI has been able to understand as well learn all the rules set for the Celtic folk song compositions on its own though carefully analysing the patterns in the fed data within a very short time.

Nanoscopic Golden Springs Could Unravel Twisted Molecules

Molecular vibration is one of the known phenomena in the world of physics. Twisting of molecules is usually observed, while the present atoms of any molecule have periodic motion. In fact, many of the molecules are found to get twisted in a variety of ways. On the basis of their pattern of twisting, they are present in the right or left handed position. Such type of twisting is known as chirality. Recently, some scientists have determined that twisted molecules may be discovered with the help of nanoscopic golden colored springs.

Scientists from the University of Bath have collected gold spring-like coils in their experiment. They are more than five thousand times thinner, in compared to our hair strands. Another component, used by these researchers is the laser, which has allowed them to identify some twisted molecules. All these trials will perhaps bring about an improvement in the design of pharmaceutical matter, nanorobotics and telecommunications. Thus, the coils assist in knowing much data on chiral molecules. However, it is important to have a good idea on chirality and how it alters the behavior of molecules in any place, including our own body.

Chirality- What it is about?

The term, chirality has been extracted from a specific Greek word, which is related to a chiral object. Any system or object is considered as chiral, while it is distinguished from some mirror or reflective image. Chiral molecules consist of a carbon-based atom along with 4 non-identical components.

With the use of laser system, the researchers are able to work on all chiral molecules. This light becomes twisted at the time of travelling. However, their research turns out to be much tricky, while the molecular amount is much small. At this point, the tiny golden springs are much useful. Their design allows the lights to become twisted. It may also adjust to molecules in a better way. Thus, it becomes quite simple to make out the microscopic amounts.

Enhancement of pharmaceuticals through the use of nanoscopic springs-

There are some springs, which are much smaller in size, and the researchers have analyzed their effectiveness. They want to know whether these springs are able to increase the interactions of chiral particles and light. The research is based on the method for converting color. This process is called as the Second Harmonic Generation.

If a spring performs better, more amounts of red colored lights are transformed into the blue ones. From the experiment, the researchers have understood that there’re high potentials in their springs. However, the expected performance depends on the angle towards which they are directed. The system works as kaleidoscope, which involves deformation. The scientists want to reduce this distortion. And this is achievable only with the optimization of springs or in other words, chiral nanostructures.

A very close observation may lead to a development of purity and design of many pharmaceuticals. According to a member of the scientists’ team, it also helps in controlling motion of miniaturize elements in the future.

Google Gives Parents Greater Powers


Google’s New Family Link Software

Wilson Rothman, WSJ personal technology editor explained on Lunch Break with Tanya Rivero that Alphabet Inc’s Google had revealed an unparalleled set of parental controls, with the beta launch of Family Link, while enabling children below the age of 13 to sign for content-restricted accounts.

Parents seems to be losing control with their children and tablets, phone as well as iPods have been pushing our kids in a digital black hole enabling less visibility in their social activities and their pastimes. Google’s new Family Link software is a relief for parents in keeping their kids under control in this digital world.

The arrival of Family Link corresponds with a change to the policy of Google on child accounts. Children below 13 years can now have them provided they are set up through the Family Link which has been authorized by a parent.

It is said to be the most inclusive set of parent tools for the internet, the greatest features which Amazon as well as Apple have provided with services of Google which is that we get this remarkable functionality by providing a little more personal information and this time it is data about the online activities of our children.

Experience Use of Android Based Device

With the Family Link account a child is capable of experiencing the use of an Android based device and the test case, a Nexus 5X in a manner which tends to look adequately like the phone of Mom or Dad’s though tends to keep the child protected from some trouble of adulthood in Google search, Chrome browser, Google Play store together with YouTube app.

Harmless search that seems to yield filtered, child-sanitized web as well as image search consequences could be through default. Google has also mentioned that search effects could, for the first time, cater to children but that would be difficult to tell. The amazing thing is for parents in the form of remote access.

Moreover, Family Link also tends to provide parents with an administrative app which they could utilise in locating the device of their child onmany ring it in case of losing in couch cushions, remotely adjust account and device settings or also do a factory-reset if the phone is lost.

Set Up Time Restrictions/Off-limits Hours

Moreover parents could also set up time restrictions and off-limits hours and see the time spent on several app by their children. As the beta version of the Family Link tends to go public individuals could request to try it though their devices need to be running Nougat which is the updated version of Android.

Google has informed that by the end of the year, it would be working with earlier versions. The company also believes in releasing a parental control app for iPhones. It is essential to know how many parental control systems are available before one decides to purchase it. They are not just built into popular devices led by Apple and Amazon but are also sold as services by third party.

Apple is said to have control both local and remote dispersed around the operating system of its iOS. The restriction unit in the setting of iOS enables the user to set a passcode in locking down from Siri and FaceTime to iTunes albums together with the feared in-app procurements

Twitter Finally Ditches Handles from Its 140 Character Limit

When one thinks of Twitter the character limit comes into the mind first because users have to express their thought within the set limits. Over the years the use of images, gifs, quotes and links has started to lower the limit of characters left to express one’s thoughts. Twitter is finally taking a stand to bring more opportunity for the users to make the best use of the character limit.

Twitter has launched a limited testing on the iOS platform to see how the new change in the character limit will perform with the audience. But from today onwards Twitter will allow users to mentions other people handle in their replies but it won’t be counted. Users will get a greyed-out line appearing right at the top of the tweet indicating “Replying to [username]’.

The current change made in the character limit is a part of plan announced by Twitter in May 2016 wherein it will slowly allow users to get more of their tweet in varied interesting ways. Twitter is struggling against other major social media platform and it is earnestly looking forward to attract more users to its network.

The Introduction of the Chronological timeline

In the February of this year Twitter brought the entirely chronological timelines for Twitter in a bid help users in catching up with the latest tweets from their favourite users. But as of today only two per cent of the total users have made the shift to this new feature. Twitter is aggressively making changes to the age-old features of its platform to bring something new and exciting for its users. Given the fact that Twitter is going through a stagnant growth period and falling stock prices the sudden changes in the character limit can be seen as a welcome addition.

List of Changes Brought in the Tweeting activity

When a person is using attachment in the tweets which may include either images, photos, videos, GIFs, polls or even quote tweets then it won’t be counted towards the 140 character limit. Secondly a new retweet button will be enabled on the user’s profile to ensure they can tweet their own tweets or people tweet as well share or unlove any older tweet with ease and simplicity. Replying has always been a tedious task in the Twitter but form now on users will get some respite the Twitter handles will not be counted as the character limit.

A number of times we have different Twitter handles mentioned right in the replies and it counts. But rpm now on that wouldn’t be the case rather Twitter handles will appear in greyed-out right at the top of the tweets which label stating ‘Replying to [username]’.

Twitter gives a solemn goodbye to the ‘@’ tweeting culture which has emerged in the recent past. Users were most likely to tag a username right at the beginning of their tweet to get the attention of the concerned person using ‘@’. But from now onwards replies to such tweet will only be seen by the sender or by the followers and simply by the person who is specifically replying to that tweet.

How to Secure Your Facebook Account

Facebook has become an important and integral part of our lives and it is necessary to safeguard online especially on the social media platform. A hack into the Facebook account will result in revealing wide range of sensitive and extremely personal information about a user to the hackers which can ultimately lead to financial, identity or emotional loss of varied kinds. Here are few smart ways to secure the Facebook account without any hassle.

Turn your account secure

Account protection begins with optimizing the passwords. Make use of numbers, letters & special characters while creating a password and for security question ensure it is known only to you. You can also set the two factor authentication system for logging into your Facebook account by going to the Settings.

Check for suspicious activity

Going to the Facebook Settings page will allow you to keep a tab on ‘from where’ your account has been accessed at any given point of time. If you has gained access to your account without your knowledge then you will be able to gain knowledge about it from here and even take steps to thwart such attempts in future.

Get a grip on your privacy

Privacy is an integral part of the cyber security of the internet users in the modern world. Facebook offers wide range of features and security measures built right into its platform which helps in safeguarding the members from the hackers, marketers as well as stalkers to a great extent.

It is extremely important for the Facebook users to think twice before sharing anything on the Facebook without choosing the setting which states who can see the posts. The setting is pretty simple opting for ‘Public Posts’ will allow your posts to be seen by everyone on the web. Clicking on the Limit Past Posts will help in hiding the older posts from the public view.

Be sensible with using the Facebook

Simply restricting who views your posts, personal information and profile on the Facebook is not enough. In order to turn your Facebook account highly secure it is vital that you apply some common sense while interacting with strangers, suspicious links, offers and other things on this social media platform. Secondly stay away from sharing critical personal information in the public domain like on Facebook pages and profiles needlessly. If you don’t want to proclaim your whereabouts then turn of location search on Facebook.

Thirdly giving every little details of your daily routine or lifestyle like where your work, when is your birthday, favourite movie, pets name, family address unknowingly through posts, location tags will only help in losing your identity.

Anyone closely following your social media activity will be able to pretend to be you with all the information you have shared online. Don’t forget to pay attention to the computers or different browsers you use in order to access the Facebook. Make sure the system or browser is up-to-date and has a robust antivirus at work.

How to Protecting Bulk Power Systems from Hackers

Consistency Measure of Electricity Grid – Escalating

Consistency measures of electricity grid have been escalating to new norm since it tends to include physical security together with cyber-security. Fears to any of them could trigger instability resulting to blackouts as well as economic losses.

Several tend to take it for granted of turning on the light. Though in reality, the energy drawn from the electrical grid in brightening homes, freeze food as well as watch TV is said to be a part of a complex together with a widespread system. Comprehending the susceptibilities of the system and the dependability is a vital step in improving its security.

Fresh research headed by scientists from Michigan Technological University explored in the so-called scenarios wherein the hackers tend to exploit the security flaws implementing a disturbing plan of cyber-attacks. Recently the Journal IEEE Transactions on Smart Grid had published their work. Chee-Wooi Ten, lead author, an associate professor of electrical and computer engineering at Michigan Tech stated that the fundamental problem was an opening between physical equipment and intangible software.

 Improvements in smart grid technology like smart meters in homes, management systems for the purpose of distributed energy resources such as wind together with solar production with instrumentation system in power plants, control centres or substations, creates improvements in monitoring as well as access for hackers.

Convenience/Cost Reduction Streamlines Process

Ten had commented that `ten years back, cyber security did not exist and the same was not spoken about and was not an issue. He jokes that people presumed that he was crazy for suggesting the possibility of power grid hacking. He further added that now with events such as in Ukraine last year together with malware like Stuxnet, hackers could plan a cyber attack which could result in larger power outages, people would begin clutching the severity of the issue.

 He further pointed that the hackers focus on specific areas of the control network of power infrastructure and targeted on the devices which tends to control it. Mechanized systems are inclined to control most of the grid from generation in the transmission for usage.

According to Ten, the convenience as well as the cost reduction of automation streamlines the process though without solid security means, it could also make the system susceptible. The interconnectivity off the grid could also result in cascading impacts leading to blackouts, equipment failure and is landing with the areas isolated and cut off from the maid power grid.

Connections/Asses Flaws Utilising Framework

Ten together with his colleagues arrived at connections and assess flaws utilising framework which would regularly assess the block of a power grid as well as its interconnection with their adjoining grids. With the use of quantitative systems in arranging cyber security protection would ensure power grids are operated in a much more secured and safe manner.

Ten also mentioned that it is like measuring blood pressure. He added that one tends to know that their health is at risk since it monitors systolic and diastolic numbers and hence one would work out more or eat healthier. The grid requires established metrics for health also; a number to gauge if one is ready for this security challenge. After gaining an understanding of the weaknesses of the system, it tends to get a lot easier to be strategic and shoreline security risks.

Tens says that in the future, improving regulations with particulars to match actual infrastructure requirements, providing cybersecurity insurance could be beneficial.

From the Butterfly's Wing to the Tornado: Predicting Turbulence

Flap of Butterfly's Wing could Generate a Tornado

An old saying states that in Brazil, the flap of a butterfly’s wing could generate a tornado in Texas, weeks thereafter. However, chaos theory state that is essentially impossible in computing precisely how it could take place and Georgia Tech scientists are making headway in getting math around the swirly occurrence behind it and called it turbulence.

Latest development from the Georgia Institute of Technology by physicists could probably help improve weather forecasts extending their range by making improved use of masses of weather as well as climate data. Turbulence could bend like a puff of air, swirl past a river bend or even churn as a hurricane. Although its curlicues may seem accidental, turbulence leaves down signature patterns which the physicists have been investigating.

 It is said that they have established a simple mathematical model which has assisted them in showing how turbulent flows tend to evolve over internals. Moreover, in a novel experiment, they have verified their predictions substantially in a two dimensional turbulent flow produced in a lab. The new Georgia Tech research suits the origins of that proverb.MIT, meteorology professor Edward Lorenzhad invented more than 55 years back, while he had recognized that the tiny forces had influenced major weather adequate in throwing long-range forecasts for a loop.

Theory of Relativity

The name of his paper, `Predictability: Dose the Flap of a Butterfly’s Wing in Brazil Set Off a Tornado in Texas?’ got transformed into the well-known slogan. The professors in Georgia Tech’s School of Physics, Michael Schatz and Roman Grigoriev together with graduate researchers, Balachandra Sur and Jeffrey Tithof, had published their research result online in the journal Physical Review Letters on March 15, 2017 and the research was supported by the National Science Foundation.

While the scientists, for hundreds of years, had utilised math in order to get a hold on the falling apple of Newton, in verifying the Theory of Relativity and speculate the existence of the Higgs boson, turbulence was like wet soap in the understanding of math. However for all its elusiveness, turbulence tends to influence with visibly coherent, recognizable, recognizing shapes. Fluid swirl tend to rapidly form themselves and thereafter seem to shift or disappear though they tend to reappear obstinately at various areas, generating transient as well as varying and still repeat the patterns.

Exact coherent structures – ECS’s

According to Grigoriev, people have envisaged these patterns in turbulence flows for centuries though they are finding methods of relating the patterns to mathematical equations describing the flows of fluid. Some of the recurrent patterns had drawn the attention of Grigoriev and Schatz which are known as exact coherent structures – ECS’s.

The physicists were given convenient entry points in computing predictions regarding what turbulence would do afterward. Regarding exact coherent structures, visually in turbulence, they tend to show up as brief moments when patterns seem to stop changing and it could be like the flow is for the time being is slowing down.

An ECS to an unqualified eye does not seem much different from the rest of the swirls and curls though one could be trained to spot them. As per Schatz that is precisely how they go about locating them and they watch the turbulence, continually taking snapshots. The flow moves around, moving around and they look out for the moment when it tends to slow down the most and it is then that they pick out a snapshot.

Flow of turbulence reliable patterns reflect dynamics

He further informed that they feed that in the mathematical model which indicates that they are close showing what the math looks like at that point. The math solution defines a point in the turbulent flow which could be worked with to figure out a prediction of what the turbulence would be afterwards.

In order to comprehend what an exact coherent structure is dynamically we should step back from what turbulence seems like visually with bunches of curls and swirls and rather look at a turbulent flow as an individual physical entity by decoding it into a crude metaphor – a swinging pendulum with a few marked peculiarities.

Rather than picturing the bottom point of a normal swing of the pendulum, the equilibrium as a steady point in a firm swing now the equilibrium is at the top most point, with the upside-down pendulum and it is unstable. Moreover, it does not swing in just two directions but in all directions. The flow of the turbulence reliable patterns tends to reflect dynamics which are back-and-forth-to-and-fro though in all types of variations.

 As the symbolic pendulum seems to swing up towards its peak, it tends to come near but never a complete stop. Rather it seems to flop over some other side. This near-halt point is equivalent to an exact coherent structure though there are some more bends in the metaphor.

Harnessed to Define Dynamics

Grigoriev had informed that if initial dynamics were ever changed slightly, an inverted pendulum can swing past its unstable equilibrium at the peak or it could halt and then start moving in the opposite direction. Similarly, the turbulent flow can evolve in various different manners after passing by an ECS.Numerous exact coherent structures with various qualities tend to turn up in a turbulent flow. Schatz had mentioned that usually people prefer to lookat steady things which seem to be unchanging like the evensymmetric normal pendulum and turns out to be unstable patterns which form a rough core alphabet which is used in building a kind of predictive theory.Withthedynamics of loose inverted pendulum now image eachexact coherent structure as a town on a map. With paths it seems to guide the turbulent flow `traffic’ toward, from, as well as each town like roadways. Grigoriev had mentioned thatthe road around as well as between towns do not change with passage of time which allowsforecastthe evolution ofthe flow. ECSs seems to occur frequently just like clockwork withthe likelihood of opening of refining predictions at regular intervals. Exact coherent structures arealready known to be existent.Schatz has commented that no one has done demonstration before in a lab experiment on how they can be harnessed to define dynamics, the behaviour evolving in time is the same,is certainly what is needed for prediction.

Using a Smartphone to Screen for Male Infertility

male fertility test
Male fertility tests are not as simple and easy to perform as the female counterparts but latest innovation made by some researchers is all set to change the game. Most of the at home male fertility tests allows users to just check upon sperm count but it leaves a wide range of other characteristics which also effects the fertility. One of the major important characteristics usually left aside in the so called in-home male fertility tests includes sperm motility which signifies how much energetic are the sperm cell while they move around.

Researchers behind the automated male fertility testing system

The researchers at the Brigham & Women’ Hospital and Massachusetts General Hospital had successfully developed a completely automated system which can effectively help in performing certain male fertility tests. This particular system is remarkable in accurately measuring the concentration of the sperm as well their motility ration by simply using a smartphone. It also requires some of the snap-on components which are quite cheap in nature.

The functioning of the automated system is quite simple wherein the users are required to place the semen sample in a disposable chamber of the snap-on component. The snap-on component is designed with precision and care and doesn’t’ looks odd at all rather it appears like a usual smartphone case. There is a disposable microchip placed in the component and the light source for effectively measuring the part of sample is the smartphones camera. The smartphone camera helps in illuminating the semen sample while sensing equipment placed in the component does the rest of the work.

A special app is required to be installed on the smartphone which in later stage makes use of the image and helps in carefully evaluating the number as well as activity of the sperm cells in the sample. However this isn’t the first of its kind male fertility testing system as there is already a similar technology called YO sperm test system which happens to be sold directly to the consumers.

How this technology works? 

Researchers have made use of as many as 350 clinical sperm specimens to analyse the results and improvise the technology with each iteration. They had made use of unwashed and processed liquefied semen in order to conduct tests. The sample were kept at less than 5-s which ensured lower processing time and helped in getting accurate results with about `98% accuracy. Under the World Health Organisation the test were conducted to ensure its integrity as well as the efficiency of the technology for global usage in the upcoming days.

Their research has also shed light to the fact that by simply integrating few microfluids along with the optical sensing accessories in the modern advanced consumer electronics smartphone can help in developing the remote semen testing equipment without much hassle. Therefore they opted for bringing the amalgamation of the technology on the smartphone which can be easily access by millions worldwide and an app has been developed to provide quick and accurate fertility test results right from the sample within shortest amount of time.

Google Play Gets a Free App of the Week Section

Google Play
Back in 2012, Apple started ‘free app of the week’ as a means of promoting some of the best titles in App stores. Google decided to follow Apple’s footsteps and has recently launched their own ‘free app of the week’ section. This new and exciting section is available on Google Play and has been launched, but not yet in India. However, this mega-tech pioneer has not yet committed to making this free application section, a full time feature. Google Play is currently testing their new approach to marketing apps only in the US, and will keep the format going for a time period of four weeks.

Free apps available 

One of the attractive features they had added on Google Play prior to this recent update was a unique feature that was greatly liked. This innovation allowed developers to display sales of their apps and other free offers on Google Play. While the recent ‘free app section also features a free download version of Card Wars by Cartoon Network for free which normally costs around $2.99. This is available on both mobile and desktop version.

This move is a wonderfully innovative approach that not only allows popularity of Google Play but gives an innovative platform to new developers. This program by Google is called the pilot program. Cartoon Network was approached by Google for offering the proposal of joining this latest venture by Google Play. Even though, CN was not thinking of running a sale, they agreed to participate in it.
Editorial selection process

An editorial selection process is being held by Google for deciding which apps will be featured in their new ‘free app of the week’ section. This editorial process is far better than some algorithm which will lead to the display of popular apps that have already been up for sale. For this program CN is giving some its popular apps for free but Google recompensing the publisher of the apps, for these downloads.

Tried and tested method 

Although, Google has decided to take up this new venture, it is not exactly ‘new’ for the company. As, back in 2015 Google had already tested the model by offering free apps in the family section. However, the format was a tad different, and Google Play was only offering free applications from PBS kids.

Well, this is also not something new for the Android users as they’ve already had the experience of downloading paid content for free. Amazon Underground was a program launched by Amazon in 2015 where Android users were able to download premium apps for free from the Amazon Appstore. App publishers in an effort to increase their Google Play ranking and for boosting downloads also sometimes offers exciting sales.

Google, however, has decided to not make comments on this business model surrounding the ‘free app of the week’ venture. A spokesperson has however stated that it is Google Play’s constant endeavor to offer their customers with the best services on Google Play. Considering the shining success of Google’s earlier efforts to boost app rankings, this new venture will be quite successful.

Heated Pavement Technology Tested at Des Moines International Airport

 Heated Pavement
We are living in future or future is dawning upon the humankind. The line is blur and the amount of scientific, technology advancement we are experiencing it will become highly difficult to pinpoint the moment we will step into the future. A team of researchers from the Iowa State University have been successful in deploying the fully functional electrically conductive concrete pavement installed on an America airport. The lead researcher going by the name Halil Ceylan has to simply run an app on his smartphone in order to begin the successful testing on the full scale heated pavement installed at Des Moines International Airport.

Winter season is round the corner the technology implemented by the Ceylan team will help in turning on heated pavement system which will allow snow and ice to melt away. All this is done through an app and it can be seen in real time due to its video capability.

How much it costs?

Most of the people are amazed by the technology and are hooked on learning about the cost incurred in developing it. Ceylan has clarified that the success of the heated pavement slabs has shown that benefits are far greater than the cost. Researchers have carefully calculated the number at the operating cost of just 19 cents per square meters which is unbelievably cheaper.

How the testing slabs were made?

The test slabs designed for the installation at the airport are made up of 1percent of the carbon fiber along with a special mix of the cement, rocks and sand. The use of carbon fiber in the heated pavement technology allows concrete to conduct electricity which ultimately helps in creating heat.

A team member has prepared hundreds of concrete samples in order to come up with the right combination of comprehensive strength, electrical conductivity, tensile strength and workability required for its success. The test slabs are wired with varied kind of sensors which includes strain gauges, temperature probes, humidity sensors as well as it has two surveillance camera mounted near it. These test slabs are powered by the hangar’s power supply which helps in its smooth functioning.

Why testing on an airport?

The reason which prompted Des Moines Airport for testing heated pavement because it’s a part of Federal Aviation Administration sustainability program. In a bid to boost the sustainability and a partnership was established way back in 2012 which brought together a number of credible researchers from the Purdue University as well as other core members from Iowa State. This brings together a number of FAA’s centres of excellence along with the federal government, universities and industry in an established one-of-a-kind cost-sharing research partnership.

This program is currently about $2.2 million for Iowa State to bring about a full scale demonstration of unique airfield d pavements as well as heated pavements for future usage. Earlier a prototype of the heated pavement was successfully placed at the campus lab which showed promising results and feasibility to integrate for the large scale studies.
