A Google Engineer Recreated a DSLR Photo Using a Nexus 6P with Absolute Perfection

Create Image Utilising Nexus 6P

Smartphone cameras have been enhanced beyond our imaginations and from the rough VGA cameras which the earlier phones featured, to the updated Dual Cameras lots that tend to replicate DSLR type portrait shots with perfections, smartphone photography had progressed to great extent.

However there seems to be one segment wherein smartphones are unable to compare up to the DSLRs low light photography and Google has plans of changing it. OEMs tend to advertise low-light photography as a feature in their phone cameras though usually it is more of a trick. An engineer Florian Kainz working on Gcam team of Google, the team behind the legendary camera of the Google Pixel had been challenged by his colleague to develop a night shot of the Golden Gate Bridge which had originally been shot by a DSLR utilising a smartphone camera.

He had accepted the challenge and had managed in creating the image utilising the Nexus 6P together with some post-processing and created an image using smartphone providing us a glimpse of what Google could do in making night-time outdoor photography a real thing with the support of smartphones.

Technique for Shooting Milky Way – Google Pixel

Using a technique he was capable of shooting the Milky Way utilising the Google Pixel from the Californian coast where the nights tend to get very dark and the stars are said to be the only source of light on nights when the moon is not in sight.

But at 9 to 10 megapixels, the subsequent photos did not seem to be as high quality as a DSLR, though the details seemed to be there. With the results of the Pixel together with the Nexus 6P, it is clear that the final frontier of smartphone photography is on the threshold of being penetrated.

Software has been developed by OEM in order to process the images internally, with all the additions together with the subtractions as well as the averaging of the multiple photos to make night point and shoot photography utilising a smartphone, a reality. But one can’t take photos yet the same way with your smartphone and the Google Pixel tends to come the nearest in taking such images though not close enough.

HDR+ Feature

Google is said to utilise the HDR+ feature that swiftly takes 10 short exposure shots and averages them to form an individual image to eliminate blur and noise at the time of collecting adequate light for good photos at practically low-levels though it will still tend to be impractical in very low-light, moonlight landscapes for example, or starlight photos.

To achieve the image, Kainz had installed a custom Android app which enabled him to set the ISO, shutter speed and focus manually. He also utilised a tripod to keep the phone steady. The custom app was to eliminate the maximum 4-second exposure time for taking longer exposure shots in order to lessen the ISO setting and thus reduce the noise.

When the shutter button is pressed, the app tends to wait a few seconds and then takes up to 64 frames with the selected exposure and ISO settings. Thereafter it saves the frames as DNG file wherein these are later exported to a PC to post-process into one.

10 Smart Gadgets That Make Apartment Living Easier

Smart Home Products Devices

The modern smartphone is still in the learning process. In the rush of the technology world in making everything internet connected, the home tends to be a space with the greatest potentials for changes and lasting effect. We tend to be dependent on the internet in making our routine life much better and effective. There are various types of smart home products devices which are inclined in controlling the functions remotely from your smartphone and this trend is on the rise.

Several renters are of the belief that they are unable to revel in the perks of smart home devices since they are incapable of altering their living spaces. However there seems to be abundant of amazing products which could be utilised in one’s rented apartment. Probably one would be on the look-out for plug-and-play devices which would need minimum or no installation that could be packed up and taken along when they tend to move out. The following devices could be impeccable for renters.

1. Smart battery which upgrades normal smoke detectors


Rather than replacing the prevailing smoke detectors with a smart equivalent, you could just update the prevailing alarms. The Roost smart battery could turn normal smoke detectors into smart devices by just installing the battery. This would not need any tools and you could just pop it up and one would be capable of getting smartphone notification whenever the alarm tends to go off or if the battery seems to be low.

2. Install free smart plug which saves energy

It could be very annoying when one is faced with a high electric bill beside the rent. However Wemo smart plugs could be helpful. You could just plug them in your prevailing outlets and then plug in your appliances. This can be remotely controlled, whatever has been plugged in the Wemo, enabling the user to turn devices off when not at home.

3. Smart controller for air-conditioner

If an air conditioner has been provided by the landlord, you could upgrade the same into a smart AC unit with the support of the Tado Smart AC Controller. By installing the controller you would be capable of controlling the appliance remotely and save around 40% on energy cost. The Tado is also said to function with heat pumps.

4. Removable smart air conditioner

If the renter is not in possession of an air conditioner, he could treat himself to a smart, affordable AC unit. Frigidaire Smart Window AC tends to provide the renter with remote control over the device and offers maintenance reminders to save the user of not forgetting of changing the filter.

5. Standalone security System

The need of mounting cameras or pay a monthly fee for monitoring your home is not essential. The Piper All-in-One Security System together with Video Monitoring is said to be appropriate for rentals. This could be placed on a shelf or table and one will be capable of monitoring your place with HD video streams with real-time notification should something go wrong.

6. Kit to turn regular blinds to smart blinds

Another product which could turn your normal apartment fixings to smart gadgets is the MySmartBlinds Automation Kit. When it is installed, you will be capable of controlling your window coverings from your smartphone and set up schedules for them to open as well as put them in energy-saving mode.

7. Easy Installation of smart light bulbs

Smart bulbs are much preferred to smart lights. There are no hubs or bridge needed for these light bulbs besides a Wi-Fi connection. These could be even synced with Alexa of Amazon and hence can be controlled with voice commands.

8. Showerhead which enables you to take phone calls

Smart showers are said to be fantastic though there are chances that the landlord may not compromise on the installation costs. This should not stop you from enjoying a tech-savvy shower. The H2oVibe Rain Showerhead could be installed on the prevailing shower enabling you to answer calls or rock out on some of your favourite hits while you shower.

9. Sleep system to block out loud neighbours

Having noisy neighbours in the neighbourhood could be very disturbing especially at night. The gadget Sense Sleep system not only produces ambient noise in blocking out disruptive sounds but it also monitors your sleep patterns providing personalized recommendations on how one could have a good sleep and wake up in the morning.

10. Pet camera to keep your dog from barking

Should the barking of your pet tend to bother your neighbours, you could try quieting down Fido with the support of the Furbo Dog Camera. This amazing device is said to send you notifications if your pet is found to be barking and enable you to talk to your dog as well as feed him a treat or two

Mind Boggling Optical Illusion Reignites the Debate Over Whether the Outfit is Blue and Black or White and Gold

dress

Strange Optical Illusion

A clip shared on Korean site Ruliweb portrayed two outfits, one black and blue while the other yellow and white which seemed to alter right before your eyes. After an ill-famed debate had divided millions all over the web, it had been reignited by a short clip portraying a strange optical illusion.

 When a small section is relocated from one dress to the other in the animation, though it tends not to alter colour, it seems to match the shade of both the dresses. As the section tends to slip from the black and blue striped outfit to the yellow and white stripe dress it seems to abruptly slot into place without any problem. This delusion is said to work by adding what seems to be a shaded blue box above the yellow dress and a yellow tinted box above the blue dress.

However the delusion on the shifting of shade is on how the colour is viewed which is one of the reasons why several debated on the original colour of the #TheDress way back in 2015. Professor of Ophthalmology in the Faculty of Medicine at the University of Southampton, Andrew Lotery had informed the MailOnline that the variance in observation was owing to lighting conditions, the device from where the image is seen as well as the age and gender of a person.

Visual system Throws Away Information

People all over the social media have been debating about an image depicting a perfectly nice bodycon dress as blue with black lace fringe or white with gold lace fringe. The debate is more than just social media and is about primal biology as well as the way human eyes together with brain have progressed in seeing colour in a sunny world.

 Light is said to enter the eye through the lens with various wavelengths matching to various colours. The light tends to hit the retina towards the back of the eye wherein pigments initiate neural connections to the visual cortex, the area of the brain which develops these signal into an image. Though the first surge of light is the result of whatever wavelengths tend to illuminate the world, reflecting off whatever one views at.

The brain on its own tends to figure out what colour light is bouncing off the image your eyes are observing and basically detracts that colour from the real colour of the object. Neuroscientist at the University of Washington commented that our visual system tends to throw away information regarding the illuminant and extract information related to the actual reflectance.

Various Combinations of Genes

Lotery had clarified that all tend to have various combinations of the genes which tend to develop the sense of colour for red, green and blue and since these genes are on the X chromosome, women seems to have added variations. As a consequence, women tend to have a more vibrant range of colour and could be more prone as well as subtle to particular colours.

 This could explain why women are casual between seeing the different colours while men typically do not tend to do so. He further went on to add that some people seem to have more than a single dose of a blue colour genes for instance and hence they will see higher or lesser stages of this colour also.

Researchers Design Moisture Responsive Workout Suit

How about an athlete's workout suit that breathe? Yes, a team of researchers belong to MIT has fabricated a workout No sweat suit that breathe. Its the great news for athlete's, ain't it?

This remarkable breathable workout bio technology suit having the flaps that ventilate by open and close in effects to the body of the athlete's body temperature and sweat.

If you closely go through this breathable work No sweat suit you may see the flaps that sizes from thumbnail to the finger sized. These precised flaps are lined with microbial cells in No sweat suit that may shrivel and enlarge in response to athlete's body temperature. These tiny microbial cells respond as smaller sensors/ actuators, that forces these flaps to open while a sportsman workouts that increases the body temperature and release of sweat. The flaps found in No sweat suit closes automatically when the body temperature becomes normal.

This team of MIT researchers have also made the athlete's shoes that are having the inner layer of the same microbial cells to ventilate the moisture.

OK! Why they use live microbial cells in inventing their No sweat suit? These scientific researchers says that these sensitive microbial cells need no other components to sense and react to wetness.

These microbial cells found in No sweat suit are also evidenced to be innocuous to touching and even ingest. These new tools of bio technology which are accessible nowadays could be fitted out quickly and also in large quantities, to explicit various utilities and especially to the moisture-sensitive.

The team has conducted a test with the microbial moisture-sensitive cells that responds not only open the flaps in No sweat suit but in addition also responds to wet conditions.

Wen wang, MIT's former research scientist says that they can reap the microbial cells with various genetic tools to produce new functionalities into the living cells. In the near future, they are planning to reap the odor releasing functionalities, thus perhaps going to gym the shirt can release good smell.

The biologists have found that the humidity plays the vital role in altering the structures and volumes of the microbial cells to certain proteins. The most interesting thing to declare here is that the MIT researchers use bacteria, yeast and other microbial cells to build this moisture-sensitive fabrics.

The initial research with the most common strain of E. Coli that was found to be swell and shrink that responds to changing humidity. They print the E.coli strains in a latex fabric begun to shrink while placing in a hot plate. The same was flatten out while exposed to steam. Thus, the researchers made this biofabric into the wearable no sweat suit specially designed for athletes.

After making the trial tests they have found this sweat responsive no sweat workout suit worked very well. This scientific MIT research team has also invented the shoes that breathe. They are also having the future plans to join hands with some sportswear companies to market their No sweat suit. They are also doing a lot of researches to make moisture-responsive bedsheets, curtains and lampshades.

Our Next Volvo or Audi May Have an Android infotainment system

Volvo
Till now we had support for multiple Android devices via Bluetooth or direct plug-ins to the dashboard to enjoy the music or to do some navigation tricks from our smartphone. But things are changing at an alarming pace for the Android in the automobile which will help in unleashing a new era of Android support for better. Google has announced that upcoming range of automobiles from the Volvo and Audi will feature the Android in its full glory in the next generation infotainment systems. This is just one of small announcement made by the Goggle and more enthralling bit will appear at the upcoming Google I/O conference.

It is better than the Android Auto 


Google has launched the Android Auto in the past which made it easier for the automobile owners to access some of the vital phone functions from the behind the wheel. This system helped in bringing a simplified interface for the users to connect with their car without the need of physically attaching the phone to the console. The best thing about the Android Auto was that it helped in accessing a number of apps right on the interface which made driving a pleasant experience with the Android device.

Both the automobile manufactures namely Audi and Volvo are taking the Android experience to the next level by basing it into their infotainment system. It is worth noting that Audi has found some success with its MMI infotainment system in the recent past while Volvo’s Sensus Connect system is very much new. The decision of bringing the Android operating system into their infotainment shouldn’t mean that the manufacturers will pull the plug of their own homegrown infotainment systems. Instead they are aiming at making the buyers comfortable by offering an easy to use Android based interface in their vehicles.

Advantages of Android as the foundation


The greatest advantage of having the Android as the foundation of the infotainment in the Volvo and Audi is that it will help in accessing the vast library of Android applications. Google Play Store boasts of millions of apps in varied categories which is expanding at every given minute. Secondly it is tough to get developers to develop apps for any third party platform but having the Android foundation will ensure that developers populate the infotainment system with compatible apps quickly without much trouble. We are expecting to get more details on this foundation in the upcoming Google I/O.

One of the Volvo official has stated that having an Android foundation will mean that the company will be able to integrate the rich ecosystem of Android into their iconic Volvo user interface with ease and simplicity. There will be huge abundance of the popular apps which will help in bringing an integrated experience to the users which has never been seen before in an automobile. At the Google I/O both the automobile manufacturer will be giving demonstrations to give a wider perspective to the prospective consumers of its next generation infotainment.

Intel chip flaw allows hackers to hijack thousands of PCs

Thousands of Window computers were exposed to remote hacking due to a security flaw in the Intel chip. Dating almost back to a decade, this bug allows hackers to remotely access the keyboard and mouse of a computer even when it’s switched off, thereby granting them complete access to that PC’s files and folders and allowing them to install viruses. In this defect, the “AMT” port security, used by IT departments to support and install softwares through remote access, can be easily bypassed by hackers.

This AMT feature is mostly used by IT administrators for remotely accessing computers for support, maintenance and software updates installation. AMT can also be accessed via a web browser interface which would be protected by an admin password and can be remotely accessed even the computer is off.Last week, Intel revealed that this defect in security meant allowing hackers to exploit computers but it is now appearing to be that one could gain access which would be as easy and simple as ignoring the requirement of a password while logging in.

The flaw was discovered by researchers at the Embedi security group and they have circulated further details disclosing that hackers could enter into a system through the AMT system by simply leaving the password field empty.Hackers can also gain entry into the system through networking ports. An address on an internal home network can easily be accessed with the help of a web browser.

Intel did not disclose any statistics on how many computers were affected because of this defect but a search on a public web ports-scanning website called Shodan revealed that more than 8,000 computers were affected. Compared to consumer desktops and laptops, this technology is present only corporate PCs but sensitive information could be exploited by hackers if they gain access.

Identifying the defect

This flaw is more likely to affect Intel Chips dating as far back to 2008 that run management firmware versions from 6 and 11.6. Intel also released a security advisory that precautionary corrective steps need to be taken for a system that is runs AMT.

Researchers at Embedi warned that any systems facing internet with open ports 16992 and 16993 were more prone to the hack. After the disclosure of this flaw, scans on these affected ports have increased in number which means that hackers are actively on the lookout for such susceptible systems to take advantage.

Precautionary measures

In order to overcome this defect in the Intel chip, Intel has advised a few precautionary steps. Firstly, one needs to determine if their system has an Intel AMT capable system. Then, the system needs to be analysed for the flaw with a tool published by Intel which lets you check if your system is susceptible and disable the AMT technology.

Next, a check needs to be made for updated firmware versions. Most of the affected and vulnerable systems are older and no longer receive firmware updates. The AMT is disabled on such computers. Intel is working hard to fix this bug in the Intel chip and their hardware partners are in process to push fixes to the vulnerable systems. It is expected that computer companies like Dell, Fujitsu, HP and Lenovo will issue their patches soon and have already issued security advisories.

Stanford Professor Uses Math to Create Hypnotic 'Neverending Bloom'


Artist Uses Golden-Ratio to Create Animated Sculptures

John Edmark has amused people the world over with his 3D printed sculptures that come to life under strobe lighting while being spun on a turntable. His range of expertise covers many things including art, photography and mathematics while he is also a design lecturer at Stanford University in California. He combined a number of his skill sets to produce the hypnotic never-ending bloom.

He calls it ‘bloom’ because it gives the illusion of a repeatedly blooming flower which is a result of complex mathematics and well-timed photography. He has used a 3D printer to model the sculpture using precise measurements and photographed the process using a camera with a very high shutter speed. The final effect is that of a hypnotic infinitely blooming movement (never-ending bloom).

Design

The design of the sculpture was inspired by naturally occurring objects that exhibit the golden ratio in their structure like flower petals, pinecones, seed heads, branches of trees, sea shells, fruits and vegetables like pineapples and artichokes and even hurricanes.

The golden ratio is formed by dividing a line into two parts so that the entire length divided by the longer part is equal to the longer part divided by the smaller part. Edmark recreates the Fibonacci series found often in nature by placing the leaves on his blooms approximately 137.5 degrees around each other. 137.5 degree is a very special angle known as the golden angle which is calculated from the golden ratio.

He starts positioning the leaves of the sculptures one by one beginning from the top of the center. But he also breaks the rules sometimes to slightly alter the positions of a few leaves which creates a dizzying distorted effect. The designer used Python in RhinoScript to code the design for the model. It was then 3D printed on a ZPrinter 450.

Movement

A turntable was built for the model to be placed on. It was then attached to a motor that powered the turntable to rotate at 550 revolutions per minute. The exact rotation speed was carefully calculated so that the turntable could be synchronized with the camera filming the movement. A camera with a fast shutter speed was placed in front of the turntable to capture videos at 24 fps.

These precise settings made sure that the video would capture each frame while a leaf turned exactly 137.5 degrees resulting in the effect of the never-ending bloom. A strobe light was fitted above the bloom which emitted a strobe at exactly the same time the camera took photographs, for an enhanced effect. The different elements put together to create this mesmerizing effect had to work in a perfect sync to produce the ultimate smooth and effortless motion.

Final Result

The final result of the never-ending bloom is completely hypnotizing almost inducing a slight vertigo. The innovative intermingling of art and mathematics could only be the brainchild of John Edmark, an artist with such dynamic prowess. His work is displayed in art galleries and museums around the globe.

Plastic Eating Wax Worms Could Solve Our Pollution Problem

A planet saving caterpillar with hunger for ‘plastic’ is discovered

Our planet is becoming a dumpster with the use of plastic in varied forms and the worst thing about it is that it isn’t degradable. However, researchers have found a new kind of caterpillar which possesses the capability to eat away the bio-degradable plastic shopping bags. This caterpillar was actually bred to be used as fishing bait but researchers has found this unique plastic breaking ability during their study. These caterpillars are also referred as wax form because they used by the beekeepers to lay eggs inside the hive and they live rest of their lives as parasites on the beeswax. Their unique environment friendly ability was unearthed by a researcher when he was indulged in removing the parasites from the honeycombs.

They carried out a study in the UK supermarket where about 100 worms were exposed to a plastic bag. Within 40 minutes researchers started looking a tiny holes appearing on the bag and in 12 hours they 92 gram worth reduction in the total mass of the plastic bag. It is worth noting that the degradation rate was way faster than ever before seen in the natural environment.

Is it really happening?

Science is not just about believing the things we see but also proving that it is happening in the right fashion. Scientists have done a unique testing to confirm whether the plastic is being broken down by the environment friendly caterpillar or they are simply chomping on it. Scientists have mashed up some of the worms and smeared them on the polythene bags and the results were positive. Later on they have found that the unique plastic degrading skills shown by the worms are very much related to their ability to digest the beeswax. It is found that the complete digesting process of the beeswax as well polyethylene is almost similar as it requires the breaking of the similar types of chemical bonds.

The future application of these new caterpillars

One of the lead researchers named Federica Bertocchini has clarified that the polymer used in plastic is also a kind of wax which can be called natural plastic. Wax chemical structure is not very different from the polyethylene. During the research, it was found that the caterpillar happens to secrete a unique chemical which help in breaking the chemical bond present in the plastic. Now the next job I front of the researchers is to identify the molecular processes involved in this reaction and get the hold of the enzyme which is responsible for it.

This research will certainly help us in saving our continuously degrading environment as well will be able to break the plastic waste on a large scale. It should be noted that low-density polyethylene and plastic bags takes as much as 100 years to decompose completely while the harder and tougher plastic variants can last for centuries. Very soon we will be able to lessen the burden of plastic on the nature by introducing the chemical or even the caterpillar in breaking down the plastic wastes.

This is Google Jump Next Generation VR Camera Rig

Google Jump
Yi Halo/Yi360 VT

Yi Technology the Chinese company in the last two years, had made a niche for itself through its amazing proficient GoPro competitors. Presently the Xiaomi supported Yi is attempting to grow in the world of VR together with 360-degree video having two cameras.

This was announced at the NAB conference in Las Vegas where one is said to be for professionals and is known as the Yi Halo which had been created in partnership with Google while the other happens to be a consumer spherical camera known as the Yi 360 VR. The Yi Halo a 17-camera monster with the potential of shooting stereoscopic vide in 8K resolution at 30 frames per second or 5.8K at 60 frames per second comes at a price of 16,999. It had been designed to function with Jump a high-end VR creation platform which had been launched by Google in 2015.

The basic notion of Jump is to encourage VR film-making by removal of some of the huge barriers. Google tends to offer the general blueprints for the ringed camera rig together with server space for edging all the high-resolution imagery together and thereafter getting to kick back when hardware firms as well as film makers tend to create content for filling its promising Daydream VR platform.

Yi – First In Action Camera 

Yi is said to be the second company who has built a ring for the platform and last year, GoPro released the 16-camera Odyssey. The company has been utilising a modified version of 4K action camera in making up the Halo. The Yi Halo also tends to have another camera than the Odyssey which is said to be placed above the rig for improved capture of 360-degree footage directly above the head of the viewer when seen through a VR headset.

Besides this it also tends to have a smartphone app, a touchscreen control panel with levels on the rig structure for filmmaker. Moreover it has a capability for these small though meaningful benefits over what GoPro tends to provide.

 For instance, Yi had been the first in making an action camera which tends to shoots 4K footage at 60 frames per second which professional GoPro users tend to cry for since the release of the Hero 4 cameras.

Yi 360 VR – Release in June 

The spherical camera which GoPro had announced recently is the Yi 360 priced at $399 which can capture 360-degree video at 30 frames per second in 5.7K resolution somewhat edging out the 5.2K resolution of Fusion. Yi had showed up at NAB complete with specs for its announcement while GoPro had been thin on details for the Fusion.

The Yi 360 VR utilises a couple of overlapping 220-degree lenses, two 12-megapixel Sony IMX377 sensors together with an Ambarella processing chip to close the footage collected in-camera. Besides this it also tends to stream 2.5K footage at 30 frames a second over Wi-Fi and user have an hour of battery life. The limited release of Yi 360 VR would be made available in June.

 In the meanwhile, both the cameras would come to the US before making it to its home base of Yi in China. Sean Da, Yi CEO had informed `The Verge’ that while he hopes Chinese VR viewership to boom in the forthcoming years, this is due to the majority of `high performance, high quality video creators who tend to be US or European creators’.

Swarms of Autonomous Aerial Vehicles Test New Dogfighting Skills

Hummingbirds, dragonflies, bats, bees, cockroaches - around the world, autonomous mini robots are being worked on, which are not only to perform specific tasks but also to interact in groups as far as possible. We can go through a lot of Technology News that buds over online and also through tech magazines.

Unmanned aerial vehicle is an important addition to manned aviation. Compared to the use of robots in the industry, which carry out dangerous or monotonous activities to assist the worker, the unmanned flying pilot relieves the crew of dangerous or monotonous missions. Possible scenarios are flying in disaster areas, inspection of supply lines (overhead power lines, oil pipelines), traffic monitoring (flying between high-rise buildings) or in bad environmental conditions (fog, storm).

Missions to be undertaken by unmanned aircraft in the future are typically complex and therefore require a wide range of capabilities. For this reason basic research is necessary on several subject areas. The Unmanned Aircraft Division of the DLR Institute of Flight Systems Technology meets this complexity by carrying out research in the following fields.

Flight control and mission control solutions with highly uncertain system and environmental characteristics, Sensorfusion and environmental awareness with camera and laser as a sensor in flight control, System solutions for extremely small footprint.

The goal is the simple and safe operation of an unmanned aircraft in unknown terrain. For this purpose, necessary intervention by the pilot is to be minimized by a high degree of automation of the overall system. In addition, the department is concerned with the simultaneous operation of manned and unmanned aircraft in a common airspace, hardware and software development as well as admissions aspects.

The applications and the associated methods are focused on modern aviation and spacecraft with the different subsystems and support processes. Research on the unmanned aerial vehicle continues to include areas that are located outside the traditional aerospace themes.

Their research results have resulted in development and evaluation capabilities that make the department an attractive partner for industry, government agencies and other research institutions outside the aerospace industry. A number of experimental unmanned aerial vehicle is available to the department to carry out the research. In addition to a fleet of unmanned helicopters of different sizes, it is also possible to use automatically controlled surface aircraft and parachute load-bearing systems for research purposes.

It is already impressive when Honda's humanoid robot Asimo slowly rises up a flight of stairs. But what fascinates the viewer is probably primarily due to the endeavour to construct a being in his own image. In fact, Asimo is dumb, is controlled from a distance, and if he does not recharge the after 40 minutes, he falls asleep.

But even if creatures such as Asimo still dominate the coverage, robotic researchers have long since found new models for their designs. For a long time, they did not have to search for it: After the principle of trial and error, Mother Nature finally produced enough successful creatures. And, by the way, has three important lessons.

  • Specialization is efficiency. 
  •  It does not depend on the size. 
  •  Intelligence is not a question of the brain volume.
Efficiency through specialization

Among other things in the world of social insects it is part of everyday life that the inhabitants of a colony share the work. Depending on the role a specimen is to fill, it often possesses an extremely deviant physique. Nor is science so far as the nature where workers and queens are born with the same genetic equipment.

In the EU-sponsored Swarmanoid project, which runs until spring 2020, more than 60 autonomous robots are to work together to fulfil different tasks. Foot bots roll on the ground and possess special sensory abilities. Hand bots can climb vertical surfaces and manipulate objects, while the camera-bearing eye bots are raised by four rotors.

The possibility to observe the world almost unrecognized from above, of course, makes the military of this world listen. And so the robotic bat, which the US Army has developed within the framework of the COM-BAT program of three US universities for tens of millions of dollars, specializes in this task: it is to look at the world in stereo, Serve as a flying hornpot, sniff out gases and detect radioactivity. The bat is about 15 centimetres long still quite large. As she sails through the air, she recharges her battery via a miniaturized wind turbine and solar cells.

NASA/FAA – Guidelines for New Airplane Crash-Worthiness

NASA in association with FAA have come together for a petrifying drop testwhich will be making way for guidelines for new airplane crash-worthiness. The scientists have strapped ten dummies of different body formsinto model of a regional jet fuselage dropping itt straight down at a speed of 30 feet per second.

 Moreover they also involved baggage in the cargo and though human would probably not withstand severe injuries in the situation, the bags got ragged right through the floor. The test had been piloted at Langley Research Centre of NASA in Virginia as part of the effort of Federal Aviation Administration – FAA, in order to consider the reliability of new planes which contains non-metallic parts.

Martin Annett, crash test engineer of NASA had informed that they were working with the FAA to update the necessities essential for the testing of next generation airframe concepts, particularly those which could comprise of composite materials. The scientist had examined what could have occurred to the structure of an airplane and the humans on board, should an accident take place. In order to do this, they released the fuselage cut-out from a height of 14 feet.

Collecting Data on Regional Jet-Sized Aircraft

Joseph Pellettiere, chief scientist and technical advisor for crash dynamics for FAA informed that they have been looking on collecting data on regional jet-sized aircraft and its performance especially metallic planes.

He further added that this way they could improve a regular baseline data which could be utilised in comparing with new and novel designs which could use changed materials. They then equipped ten dummies with transducers for testing the loads as well as strains on their bodies buckling them into conventional airplane seats.

The dummies had been designed to imitate actual travellers representing a variety of body categories. As per NASA, eight of the dummies were said to be 50th percentile males that had been exhibited after the average man in height, mass and proportion.

One is said to be a 95th percentile male and is designed to be heavier as well as taller than 95% of men while the tenth is a 5th percentile female of around five feet tall and 110 pounds. Together with the setting of the dummies with transducers, the engineers had also connected instrumentation in the model cross section of the fuselage also which enabled them to view how it held up under the effect.

Data Recorder to Measure What Occurred During Crash

Moreover they also placed baggage into the mix. Annett commented that one thing which was unusual in the test was that they had included baggage in the cargo hold which was an actual unclaimed baggage from an unclaimed baggage centre in Alabama.

They wanted to see how the luggage would interact with the subfloor separating it from the dummies. Justin Littell, test engineer of NASA also commented that they had put a data recorder in one of the bags in order to measure what occurred to it during the crash.

The engineers had dropped the cabin onto two feet in one trial. With the use of a technique known as full field photogrammetry, the camera was capable of capturing distinct deformations of the craft, created on black dots that had been painted around the tube.

Recording 500 frames per second, the camera followed each of the dots showing the changes. Though, the dummies received a `good jolt’, the researchers informed that they probably would have made it through all right.

Building Cities of the Future Now

Future city

Cities Upgraded for Future

New cities are being built around the world and the ones that have been lived in for years are being upgraded for the future. It is partially the cause of over-crowding as well as pollution and partly due to an ever-connected world that makes sense to peg entire cities up to the network.

A smarter city would mean that utilises data on traffic for easing congestion or one which focuses in linking services for provision of improved information for the citizens. For several it could be about making cities much greener as well as efficient.

Some of the technology companies like IBM and Cisco tend to see smart cities as large business opportunity though in conjunction with the schemes being advertised by technology companies seems to be more grass root project that targets to empower citizens enabling them a say in how the city would be viewed.

For several of them, Songdo in South Korea is the poster boy of the smart city and the $35bn project situated on reclaimed land towards the Yellow Sea has been generally considered to be a model for smart cities across the world when it had begun in 2005.

Information System – Universal City of U-city

Songdo’s information systems, also known as a universal city of U-city, seemed to be connected to each other. Moreover it had led critics to label it as a `city in a box’, a showcase for technology though not essentially the perfect city for people. Sensors seem to be on everything in Songdo, for instance, escalators tend to move only when someone is on them.

A telepresence system built in like a dishwasher is present in every home. Besides permitting users to control the heating system and locks, it also provides video conferencing and is designed to deliver education, government services together with health care. Offices as well as schools also tend to be linked to the network. The digital organizer behind Songdo is said to be Cisco supplying the network-based technologies that are needed.

Masdar, United Arab Emirates

Masdar which is meant as `source’ in Arabic is said to be a city which tends to stand in the centre of the desert of Abu Dhabi in the United Arab Emirates and is created to be one of the most ecological on the earth. Having solar power station at its core and wind farms giving energy for the same it tends to be carbon free. Besides this, it is also a hub for clean-tech companies.

From water right up to garbage, everything in the city is said to be measured and monitored, thus being a source of information. The city is said to be constructed on raised platform enabling easy access for the `digital plumbers’ to the system of progressive technologies which seem to run it. It is also pedestrian friendly and totally car free.

The city is said to be carrying out trial with a network of electric driverless podcars. The personal rapid transit – PRT would be running 6m beneath the street level through the city. The architects’ firm of Norman Foster who had designed various striking buildings inclusive of The City Hall in London have designed the buildings in the city.

It is expected that around 40,000 people would ultimately reside in the city with around 50,000 shuttling there daily.

Rio De Janeiro, Brazil 

City mayor Eduardo Paes had commissioned IBM in creating a city-wide operation centre connecting all the 30 agencies of the city from transport to emergency facilities. This shows that the officials from all over the city could join forces in handling the movement of traffic together with the public conveyance system as well as ensure the power and the water supplies function proficiently.

Synchronized response can be taken in case of a crisis, like collapsing building. Shutting down of transport system, emergency services can be organised together with gas supplies to be cut off while citizen can be updated of substitute routes through Twitter.

The research team of IBM have developed a sophisticated weather forecasting system wherein it takes data from the river basin, land surveys, the historical rainfall logs of the municipality and radar feeds to forecast rain together with the probable flash floods.

It has also begun appraising the effect of weather occurrence on other city conditions like city traffic or power outages. Several citizen-centric apps have been laid by the centre with updates on weather and traffic.

Barcelona, Spain

Last year, Manel Sanroma, chief information officer of Barcelona city council had made a daring statement that the cities of the future could be more powerful than nation states. He had stressed at smart city conference around the world the need of having a strong mayor who would be willing to take control in drawing up blueprint for this type of a city.

Barcelona is considered to be leading and tends to have some remarkable projects which are being rolled out. It has developed well-organized bus routes, modernized rubbish collection utilising sensors as well as introduced smart street lights. The development of a city operating system bringing all systems together in one location is also organized.

 Mr Sanroma had informed BBC that contrasting to Rio no central control room will be there. Presently the biggest projects under development would be to present contactless payments all over the transportation services of the city.

 Besides this, Mr Sanroma also intends collaborating with the other cities. With this it has set up the City Protocol Society with the intention of joining up cities all over the world with businesses, universities together with the other organisations in developing standards for technology platform which would operate in any city.

London, England

Several areas of London dating back to Roman eras seems to be an apparent choice as a future city though there seems to be numerous projects that are presently being developed. On a £24m prize awarded by the Technology Strategy Board in creating a future city it had lost out to Glasgow, though it remained a testing ground for smart technologies.

London has been chosen as an incubator by IBM for testing the algorithms which could power the cities of the future and has been partnering with Imperial College and University College London on various projects, inclusive of a network of sensors in monitoring air quality, water supply and the traffic flow.

Biased Bots: Human Prejudices Sneak into Artificial Intelligence Systems

Bot

Biased robots are here with human prejudices seeping their AI

Most of the AI experts believed that the artificial intelligence will offer objectively rational and logical thinking for the robots and systems in future. But a new study has is showing a darker path for AI wherein the machines are acting reflection so human and the AI is prejudiced with the human notions.

It has been found when the common machine learning programs are trained online with the ordinary human language then they are likely to acquire the cultural biases and this can get embedded right into the patterns of their wording. The ranges of these biases are quite erratic from the preference to certain lower to having some objectionable view about the race or gender.

Security experts has stated that it is extremely critical and necessary to address the rise of biases in the machine learning at the earliest as it can seriously impact their reasoning and decision making in future. In upcoming days we will be turning to the computers for processing a number of things ranging from the natural language translation for communication to making online text searches as well as image categorization.
Fair and just

Arvind Narayanan, an assistant professor of computer science at the Center for Information Technology (CITP) at Princeton has stated that the artificial intelligence should remain impartial to the human prejudices in order to offer better result and judgment making skills. He asserted that fairness and bias present in the machine learning has to be taken seriously as our modern will depend on it in near future.

We might soon be finding ourselves in the center of such situation wherein modern artificial intelligence system will be frontrunner is perpetuating the historical patterns of bias within the system without even us realizing it. If such events comes in the future then it will be completely socially unacceptable and we will still remain good old times rather than moving forward.

An objectionable example of bias seeping into AI

Just a few years ago in 2004, a study was conducted by Marianne Bertrand from the University of Chicago and Senhil Mullainatahan from Harward University. These economists conducted a test wherein they sent out about 5000 identical resumes to over 1300 job advertisements.

They only change the name of the applicants’ names which happened to be either the traditional European American or the African American and the results they received were astonishing. It was found that the European American candidates are 50 percent more likely to get an interview than the African American candidates. Another Princeton study has shown that the set o African American comes more unpleasant associations than the European American sets when it is run through automated system run by the artificial intelligence based systems.

Therefore it has become a necessity to distance the AI from the biases and prevent the cultural stereotypes from further perpetuation into the mathematics based instruction of the machine learning programs. It should be taken as the task of the coders to ensure that machines in future reflect the better angles of the human nature.

Metal as Fuel? These Canadian Scientists are Working to Make it Happen

Can we turn metal into fuel? Canadian scientists are just doing it.

The fuel as we known petroleum and gas will be over in next two decades and we have very little time come up with an alternative. So as per the mainstream technology news some of the Canadian scientists have found of turning the metal into fuel for vehicles in near future.

The researchers from the McGill University have been aggressively studying the combustion capabilities of the metal that also for over a decade. An experiment conducted by them last week in the space has helped in bringing a new twist to their hope of turning metal into fuel.

How this study has helped the scientists?

The technology news has affirmed that the reason behind conducting the experiment in space has the scientists in understanding the way practices react in weightlessness state. Using metal as a fuel is still a farfetched and unusual concept which seems to be an exclusive matter of science fiction but still it can be turned into reality. One of the researchers present in team named Andre Higgins has been studying and working on the concept of turning metal into fuel over two decades.

Collectively they had found that turning metal in powder can help in creating fuel which can be fed to the burner. This fuel will be highly efficient and it will help in releasing more energy and heat per litre of iron power than what is achieved today with a liter of gas.

Quite interestingly the residue in form of iron oxide can again be collected using a vacuum to act as the fuel again. Higgins proudly states this theory as the closed loop system which has higher efficiency than the bio fuel as well as the modern day fuels used in the vehicles.

Saving the planet with green fuel

Metal fuel will not be a ‘green’ fuel and the threat to the Mother Nature and global climate changes will be aggravated if we bring the metal fuel in daily usage. Technology news further shed light onto how researchers will be employing a noble way of recycling the metal fuel with closed-loop system.

These researchers have studied the metal fuels for over a decade which has helped in understanding how it can be brought into fruition for the benefit not the smaller vehicles like cars but also the large vehicles like ships and trains.

A state like Canada which has abundant of metals will certainly see the economic benefits of the shipping metal fuel to other countries. Countries suffering from acute air pollution like China will benefit from the truly closed loop system of the metal fuel.

The biggest benefit of the metal fuel is that it works in closed system wherein the materials will go around and around without causing any harm to the environment. Technology news also brought a revelation that metal fuels isn’t a new thing as NASA has already been using about 16 percent Aluminum powder for its space shuttle’s rocket boosters for quite some time.

Graphene Based sieve Turns Seawater into Drinking Water

Graphene

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

Fingerprint
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

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.
