Airbus Patents Radical Design With Wraparound Engines Along its Body

Airbus

Airbus Patent – Replacement of Large Engines under Wing


Airbus has filed a patent which recommends the replacement of the large engines under the wing with multi-fan jet engines which wrap around the fuselage of the airplane. The design is said to scoop up air, pushing it over the exterior of the engine in order to provide extra thrust. However, the engine nacelles would be blocking the sky-high views that flyers tend to enjoy from the window seat.

The window seat is a sought after section on an airplane but the new design would now make it the least favourite place. The aircraft manufacturers seem to be working constantly in enhancing propulsive efficiency without the need of changing the design of the plane. The patent published on Espacenet reads - `in the aeronautical industry, the current trend in turbofan design is to increase the bypass ratio in order to improve fuel consumption through increased propulsive, efficiency and to reduce noise on ground.

In conventional turbofan engines, the pursuit of higher propulsive efficiency needs increasing the fan diameter in order to produce a higher by-pass mass flow at lower slipstream velocities’. Sources reports that some may state that several airliners tend to use jet engines though they essentially use the ones which look like jet engines and are actually just turbofans.

Quest for Powerful & Efficient Engines


The difference between the two is, a jet engine tends to use thrust of the exhaust in order to manoeuvre and this system seems to work amazingly in small fighter planes though to use it for a commercial airliner would need too much fuel. A turbofan engine tends to have a turbo jet engine as its centre and the thrusts seems to move the craft though it uses a huge fan on the front to scoop up air and push it over the outside engine to provide the extra thrust for the plane.

The quest for more powerful and efficient engines, according to Airbus has led to bigger and bigger turbofans which are quickly reaching the design limitations. Multi-fan engine can be fixed to the fuselage of the aircraft which will enable the fans to scoop up airflow, moving it over the engine and providing the plane with an extra thrust.

View Blocked by Engine Nacelles


But the drawback is that the flyers would not be in a position to catch the sites from the sky anymore since their view would be blocked by the engine nacelles. Airbus also intends proposing a design which would be replacing the huge fan with a group of smaller ones but this is not a new concept.

 The firm has additional details in the patent which have not been taken into account earlier. The patent states that `a multi-fan engine including a gas turbine engine, a casing and fans encased by geared rings that connect with the geared rings of an adjacent fan like the rotation of one fan rotates the other fans’.By applying the geared rings to individual fans, the amount of torque is controlled by adjusting linear actuators.

The design would tend to be lighter since the need for heavy gearboxes and shafts that generally sit adjacent to the fan will not be needed which will free up plenty of space. With the use of these components, the inspections and servicing of the fans would be more convenient.

Why Google Would Care About Making a Keyboard for the iPhone

Google

Google Developing Software Keyboard on iPhone/iOS Devices


According to reports of Casey Newton, Google has been developing a software keyboard on the iPhone and other iOS devices but it is not known if the same has been released to consumers. Google has not made any comment on why the company is keen in making a keyboard for its arch-rivals.

Google tends to make several apps for the iPhone right from maps to its various Google Drive applications which feeds directly into well-known service that millions of users have already been using. As per Newton, the keyboard is said to serve an identical purpose by incorporating Google’s search engine directly in the keyboard which would be convenient for the many people who desire to use Google for searches.

Moreover it would also provide the company with another point of contact with the consumers. Google has been leading in the search game though it is changing considerably since people have begun utilising their phones to search instead of their computers. Google has been feeling the effect of it in some ways, for instance, mobile ads do not tend to cost much as desktops ads and delivers lower returns for Google.

Use of Apps – Increased Tremendously


Though the firm is not in trouble, with most of the $21.3 billion pulled in by way of revenue than its parent company Alphabet, reported last month, this shift seems to be a point of concern for Google. The other problem is that the use of app has increased tremendously, thereby decreasing the overall mobile searches.

As reported by Newton, people tend to turn to more apps, and seems to use search engines less. It is quite normal for some users to search for `Twitter’ or `Facebook’ instead of navigating directly to the site on a desktop. However if someone is on the phone, there is a possibility that they will only tap on the dedicated app instead of going through the mobile Web version of those sites.

The same is applicable for review sites like Yelp or travel sites like Expedia. Constructing search straight in the keyboard could help Google increase mobile searches by making a search greatly convenient. Newton’s report that Google has also been looking into incorporating other features like GIF as well as image searches would add more value to the program.

Search Button on Mobile Keyboard – Helpful


Apple began permitting third party keyboards on the iPhone from iOS 8 opening its user base to various other smaller companies that tend to make keyboards with features which Apple does not seem to offer in its stock of keyboard.

With the addition of new keyboard, users would have to do a bit in exploring their settings though several companies like Swype have informed a significant increase in users since the change in policies of Apple. Keyboard with built-in search feature would support Google in making money, since it is said that people do not use Google searches on their mobile as much as they tend to do on their desktop.

Without the search pages which tend to sell ads, Google would be losing money and as the mobile internet seems to get bigger and bigger, it could get worse. Sticking a search button on a mobile keyboard would be of great help.

The Long-Awaited Promise of a Programmable Quantum Computer

Quantum Computer

Controlling Quantum Particles – Run Quantum Procedure


One of the great challenges of the 21st century physics is the quest to build aninfluential quantum computer and though the obstacles seem significant, physicists have been chasing them down, one after the other. They have steadily learned in controlling quantum particles with the precision needed to run quantum procedure on a small scale with a few qubits.

The big test is now scale, combining these techniques in which they can manage large number of qubits and perform powerful quantum calculations. Recently Shantanu Debnath together with his pals at the University of Maryland in College Park unveiled a five qubit quantum computer module which can be programmed for any quantum procedure.

However, significantly, it is said that this module could be connected to others for the performance of powerful quantum computations concerning huge numbers of qubits. Debnath and his pals state that `this small quantum computer could be scaled to larger numbers of qubits in a single module and can further be expanded by linking several modules’. For nearly 20 years, physicists have been capable of running quantum procedures on quantum computers and the first two and three qubit machines had begun number crunching towards late 1990s.

Quantum Processes – Series of Logic Operations


However, since then, the progress had been stalled due to the dangerous difficulties in connecting large numbers of quantum particles together while maintaining their quantum states. The new device is built on the extensive work over the last two decades on trapped ion quantum computers which comprises of five ytterbium ions lined up and trapped in an electromagnetic field.

 The electronic state of individual ion is controlled by annihilating it with a laser which enables each ion to store some of the quantum information. Since they are charged, the ion exercises force on each other causing them to vibrate at frequencies which can be accurately controlled and manipulated.

 These vibrations tend to be quantum in nature enabling the ions to get entangled and in this way, the quantum bits they tend to hold can then interact. Physicist tends to carry out quantum logic operations by controlling these interactions. The quantum processes are a series of these logic operations which following one after the other.

Performing Arbitrary Series of Operation Essential


The capability of performing an arbitrary series of operation is essential. Few of the quantum computers seem to be capable of doing this and most of them have been designed to perform a particular single quantum process, which is what Debnath and his pals intend to change.

 The researchers have built a self-contained module which has the potential of addressing individual ions with a laser and read out the results of the interactions between qubits which seems to work well. The team has put the device through its speeds by applying various different quantum procedures. They have stated that `as examples, they had implemented the Deutsch-Jozsa, Bernstein-Vazirani and quantum Fourier transforms procedure.

 The procedures presented here demonstrate the computational flexibility delivered by the ion trap quantum architecture’.Though it is impressive, the team claims that it can go still further and in particular, they state that their module is scalable and several five qubit modules could be linked together in forming a more powerful quantum computer.

Intel Puts the Brakes on Moore’s Law

Intel

Intel – Slowing of Moore Law


A slowing of Moore’s Law which is a technological phenomenon that tends to play a role in mostmain advance in engineering and technology for years, has been signalled by chip maker Intel. Since 1970s, Intel had released chips which fit twice as many transistors in the similar space every two years with a goal of following an exponential curve called after Gordon Moor, one of the cofounders of the company.

Computer have become more powerful, compact and energy-efficient, due to continual shrinking and has helped in bringing about the smartphone, powerful Internet services together with breakthrough in fields like artificial intelligence and genetics. Moreover, Moore’s Law has become shorthand for notion that anything related to computing tends to get more accomplished over a period of time.

However, Intel had revealed in a regulatory filing last month that it intends slowing the pace where it launches new chip making technology. The breach between successive generations of chips with new, smaller transistor would widen and with the transistors in the latest chips of Intel, already as small as 14 nanometers, it is being more difficult to shrink them further in a way which would be cost effective for production.

Additional Performance Upgrades


The strategy of Intel to shift is not a surprise and it has already pushed back the debut of its first chips with 10 nanometer transistors from the end of this year to somewhere in 2017. However it is observed that the company has presently acknowledged that it was not a one-off and it cannot keep up the pace it used to keep.

This would mean Moore’s Law would be slowing down also. It does not mean that the devices would stop improving or ideas like driverless car would be stalled due to lack of processing power. Intel informs that it would deliver additional performance upgrades between generations of transistor technology with enhancement to the designing of the chips.

The Intel chips are basically immaterial to mobile devices, a market controlled by competitors who are usually behind in years with regards to terms of shrinking transistors and accepting new manufacturing technologies.

Intel – Switch Away From Silicon Transistors


It is also debatable that for several important new use incidents for computing like wearable devices or medical implants, chips have already been adequately powerful and consumption of power has become more important. However, raw computing power is still important and putting more of it behind machine learning procedure has been vital to the latest breakthroughs in artificial intelligence, for instance and Intel will probably deliver more bad news regarding the future of chips and Moore’s Law very soon.

The chief of manufacturing of the company, had mentioned in February that Intel desires to switch away from silicon transistors in around four years and stated before admitting that Intel does not have a successor lined up yet, that `the new technology would be basically different’.

 There have been two leading candidates, technologies known as spintronics and tunnelling transistors, though they may not provide large upsurges in computing powers. Both are far from being ready for use in making processors in huge volumes.

Gmail Will now Warn You if You’re Being Targeted by the Government

Gmail

Gmail Security Warning


Apple is not the only company that has been combating against government backed cyber-attacks. While Apple and the FBI dispute over the security of the user, Google has been bringing security in focus in a different way, by telling you what is going on. The company would be increasing the perceptibility of Gmail security warning in an attempt to help people in protecting themselves while sending and receiving emails.

One of the changes seems to be the expansion of the `safe browsing’ notifications that tells the user when they are about to open a suspicious link from an email. The warnings could appear when a link has been clicked but before the link really opens, it presents the user with a last option to withdraw instead of visiting the page. Earlier a warning was only shown before a link was clicked though no block seemed to appear if the user had not seen the warning or clicked it.

Google expects that this new additional warning would be helpful in stopping users from visiting malicious sites. Google also tends to continue the fight against state-sponsored attacks, portraying a full page warning when one is being targeted by a government-backed hacker.

Gmail Accounts Targeted by Government-backed Attackers


In a blog post, Google had mentioned that less than 0.1% of Gmail users would be receiving this kind of warning, but it highlights the importance of the warnings due to the fact that those often receiving them seem to be journalist, policy-makers and activists.

 The new warning of the state-sponsored attacks could be portrayed in addition to or instead of current warnings which Google tends to have in place for state-sponsored attacks. Google has been complaining of Gmail security a bit recently and last month had made an announcement that it would be warning users who seem to send email to recipients who were not utilising TLS encryption.

As per Google, after adding this message, the number of emails that were sent over encrypted connections had increased by around 25%. In an update in the manner that Gmail intends to be more secure, Google revealed that around 1 million Gmail accounts could have been targeted by government-backed attackers so far.

Striving to Improve Safe Browsing/Enhance Email Encryption


Google did not disclosethe precise number and did not provide any explanation on how it knows when these hacks tend to take place. When a hack is identified, a pink Warning tab tends to appear on top of Gmail prompting affected users to protect themselves.

 The company also made an announcement recently that besides the bar, users would also get the full page warning with instructions on how to stay safe. This is what will be seen if a government is trying to hack into a Gmail account. Google, in its security update, mentioned that is striving to improve its Safe Browsing warnings which appear in Gmail each time a user clicks on what is believed to be a shady link which could lead to malware or phishing attacks.

Google intends to further enhance email encryption and the company has partnered with Comcast, Microsoft and Yahoo in submitting a draft IETF specification for `SMTP Strict Transport Security’, and Google together with its partners desire to ensure that encrypted email remains encrypted all along the complete path from sender to recipient.
