Flying cars: A 1950s dream takes to the skies without the rules to stay airborne

Flying car
A sports car with swivel wings that can get in the air: What acted like a year ago is now reality. The Slovakian flight car has a wonderful Technology can now be pre-ordered and is scheduled to take off in three years.

In Monaco, Aeromobil – the Flying cars company from Slovakia presented the final design of its flight car, which will cost between 1.2 and 1.5 million euros and will be delivered from 2020 onwards.

Aeromobil, the Flying car has the technology should be transformed into a plane in less than three minutes. The wings can be folded away for travel on the road. This company has an idea to build upto 500 copies of its first model. Like other competitors, the aircraft may only be launched and landed on conventional airfields or other areas explicitly released as an aircraft.

In order to drive and fly with the vehicle, the pilots must have both a driving license and a pilot license. Aeromobil deliveries are scheduled to begin in 2020, commented Stefan Vadocz- Chief communication officer. The company is already accepting pre-orders now. Until such aircrafts become the mass transport means, sometime should pass! Government is working around the world on to regulate the operation of unmanned drones and driverless cars in the future.

However, small airplanes for passenger transport are currently considered an exciting topic in the aviation and IT industry. Aeromobil is not the only company that relies on flying cars for super-richs. In addition to the Dutch company PAL-V, which has recently offered its model "Liberty" for sale, Terrafugia - the Flying cars company is also working on a similar hermetic car and plane.

The US Company was founded by five MIT graduates. For a $ 10,000 deposit, Terrafugia – the Flying cars company is already making reservations for its two-seater flight "Transition". Terrafugia is targeting first deliveries for the year 2019.

Aeromobil with 750 km range

According to this Flying cars company, the vehicle operates in a wonderful technology with standard gasoline already fulfills all necessary regulations for road and air traffic. With wings folded backwards - similar to an insect - it should also find sufficient space on every normal parking lot and thus be suitable for everyday use.

Able to take off, the wings must first be extended, which is to be done within three minutes, according to AeroMobil. Then the driver or plane needs only a meadow, on which now 8.8 meters wide flight car is accelerated to 130 hours kilometer, then ascend to the sky. There, speeds of up to 360 kilometres per hour are to be reached, on the road the maximum is about 160 kilometres per hour. The AeroMobil, driven by a hybrid engine and a propeller in the rear, could fly a distance of 750 kilometers fully, says the Flying cars company.

Aeromobil also works on a flight and vehicle for urban transport. Together with the Audi subsidiary Italdesign, Aeromobil is developing a passenger cell, which is to be flown through the city by autonomously controlled and electrically operated drones.

The Uber service has recently brought on board an expert on flying cars, which has been able to take off and land precipitously for decades on smaller vehicles. However, it does not want to produce its own flight cars, but sees itself as an "acceleration catalyst" for the newly-formed flight car industry.

In other words, its customers should first take conventional over-vehicles to a flight taxi stop in a residential area. From this "Vertiport" customer could then fly to the next stop near their workplace.

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.
