Samsung Looks to Get a Head Start On Apple with Its Next Jumbo Smartphone

Samsung had long been the top Smartphone maker which had the highest market coverage over the years with its flagship Galaxy S models. But Apple slowly and surely crept on and finally seized the top Smartphone coverage by sharing it with Samsung this year. Samsung is hoping to make considerable leap in the market by launching its new jumbo sized hybrid between Smartphone and tablets ahead of Apple.

Samsung is set to release the new entrant in Galaxy Note and Galaxy S flagship with Note 5 and S6 Edge Plus. Galaxy Note 5 will possess a metal black body instead of the plastic along with a hugely improved stylus. On other Galaxy S6 Edge Plus will feature a 5.7 inch screen which curves over the sides of the device.

Samsung quietly shifts the launch date

Samsung for a long time had kept introducing its Smartphone at the Berlin based IFA electronic in September but this time it’s releasing much earlier than expected. The reason for releasing the new devices ahead of schedule in its New York is attempt to counter the release of Apple’s next iPhone, which will be unveiled in early September.

The next iPhones will possess bigger screen, which is creating pressure upon Samsung to get into market earlier with its bigger devices and dominate over the market with boosting of sales. In simple words Samsung is saying its customers to look out for its devices to buy this time around. Samsung Note line will be launching ahead of the bigger screen iPhone for the first time in the market with the release of next iPhone in the September 9 event.

Apple goes the bigger way

Apple devices were usually happened to be smaller in size but great in performance. However, Apple even jumped into bigger screen by introducing new iPhone 6 and 6 Plus which took away the shine and advantage from the Samsung devices. Going with bigger screen helped Apple churning out immense sales with 47.5 million devices sold in just June quarter, which is 35% hike against the previous year stats.

With bigger screen iPhones Apple made its entry into the phablet business with pomp and success. It should be noted that 13% of Smartphone sold in US in the second quarter were devices with 5.5 inch screen or larger. Apple is on the verge of quickly dominated in the Phablet market which was once dominated by the Samsung Note and Galaxy devices.

Samsung rise up to the challenge

Samsung had made significant changes in its Note line by bringing hardware redesign to lend a more premium feel to the device and divert them from the Apple devices. Though Samsung had not much change to its Galaxy S Smartphone over the years and this time they had introduced much talked curved screen. In order to compete in the highly competitive Smartphone market it is necessary for the Samsung to create buzz among the consumers and get them excited about its Smartphones, otherwise it will be extremely tough to challenge the rise of other Smartphone maker and most importantly Apple.

Hackers Target Internet Address Bug to Disrupt Sites

Hackers Manipulating Internet Architecture

According to a security firm, it is said that hackers are manipulating a serious flaw in the internet’s architecture wherein the bug seems to target systems that tend to convert domain names into IP addresses. Taking advantage of it could impend the smooth function of the internet services since it would permit hackers to launch denial-of-service attacks on websites, possibly forcing them offline and regular internet users would unlikely be severely affected.

Bind seems to be the name of a variety of Domain Name System – DNS software which is used on most of the internet servers. The most recently discovered bug enables attackers to crash the software thus taking the DNS service offline and stopping URLs for instance, from functioning. Patch for the fault is made available, though several systems need to be updated.

 The ISC – Internet Systems Consortium that had developed Bind had mentioned in a tweet that the vulnerability was `particularly critical’ and `easily exploited’. Last week ISC had release a patch for serious vulnerability in BIND, one of the popular Domain Name Servers which is bundled with Linux.The flaw that affects versions of BIND 9 from BIND 9.1.0 to BIND 9.10.2-P2.

Fault in Handling TKEY Queries

It could be exploited to crash the DNS servers running the software followed by a DoS attach. Red Hat, Ubuntu, CentOS as well as Debian have all been affected with the bug and so patching is straightforward, update or apt-get update, whichever is suitable to the environment together with a DNS server restart.

 A networking expert at Sucuri, Daniel Cid, had published a blog post stating the vulnerability wherein he had clarified that the real exploits taking advantage of the fault had already taken place, based on the reports received from the customers of the company, that they were facing DNS server crashes. He also informed BBC that a few of the clients in various industries had their DNS servers crashed due to it.

He further added that due to their experience, server software such as Bind, Apache, OpenSSL and the others did not get patched as often as they should. According to a report in The Register, CVE-2015-5477, last week, there is a fault in handling TKEY queries, like a constructed packet could use the defect in triggering a REQUIRE assertion failure, which could cause BIND to exit. Cid informs that it is also trivial to check if the DNS server is being targeted.

Large DNS Exploits Take Down Hunks of Internet

One could look for the ANY TKEY in the DNS logs with querylog enabled since TKEY request seems to be `not very common’ and should be easy to notice suspicious requests. Brian Honan, cybersecurity expert, had commented that a spike in exploits of the fault was expected in the next few days.

He further added that the websites would frequently be accessible through other routes and cache addresses on DNS servers all over the world even though certain key DNS servers have been made to crash. He stated that `it is not a doomsday scenario but a question of ensuring that the DNS structure could continue to work while patches tend to be rolled out.

According to Mr Cid, the impact on general users is probably to be minimal and the average internet users will not experience much pain besides a few sites and email servers down. A large DNS exploit could take down hunks of the internet.

Bottom-up Assembly of Metallic Germanium

Chip makers were aggressively researching on finding new materials to boost the chip performance in respect to bringing further miniaturization. Chips are known to get smaller and better in performance over each passing decade. This is achieved by finding new materials which can boost the performance at the same time working efficiently with the present platform. Currently chip manufacturers are utilizing the metallic germanium in order to maximize the potential of the chip in terms of performance and functionalities which integrates well with the silicon platform.

The features of metallic germanium

Germanium fits well all the requirements and it is widely used as a high mobility channel materials, a plasmonic conductor and a light emitting medium in the silicon integrated lasers. The reason for its being successful is it possesses a high electron density in three dimensions (3D).

A simple approach can help in demonstrating the 3D assembly of the atoms found in the germanium by repeated stacking of two dimensional (2D) high density phosphorus layers. This results in producing a high density with relatively low resistivity metallic germanium of precisely defined thickness.

How germanium happens to work so efficiently?

In order to demonstrate the ability of the free electrons of metallic germanium converting from 2D dopant layers into a homogeneous 3D conductor certain specific measurements are used such as quantum interference measurements, density functional theory and atom probe topography. Metallic germanium is doped with homogenous concentrations of free electron which helps in creating low resistivity source or drain extensions in high mobility transistors.

It is not feasible to use the mainstream top-down implantation for this purpose as enhanced dopant diffusion and formation of neutral complexes will create an electrical deviation. In order to control doping process from the bottom up self limiting surface reactions can be used.

This approach will lead to the creation of monolayer-doped semi conductors with much needed high density, two dimensional electron gases which are strongly confined. Utilizing the two approaches- the bottom and top down- it helps in extending the monolayer doping from just 2D to 3D. In this specific case the dopants are easily deposited in a single 2D layer while their effective distribution in 3D is obtained by thermal diffusion. The bottom up assembly of the metallic Germanic is only achieved by the repeated deposition of N nearly identical phosphorus doped layers. This approach helps in preserving the vertical atom precision which is associated with the monolayer doping and helps in creating homogenous 3D system.

Metallic germanium stamps its great performance over others

Mostly bottom up approach is used by the researchers and manufacturers which helps in achieving doping in Ge capable of producing high electron densities and low resistivity metallic conductors. The application of this technology and substance is of great relevance in the electronic industry along with photonics, plasmonics and others. Metallic germanium is actively used in the development of the high mobility transistors, mid-IR plamonics bio-sensors and industrially viable Si-integrated lasers.

Google’s Alphabet

Google took the world by surprise when it announced its creation of a new parent named “Alphabet Inc”. Google had made it clear at the announcement that this particular entity is intended to build any products and brands. However many companies having similar name were quite taken aback with this development and viewed it as a potential trademark infringement instance if Google goes further by bringing in products and services under this brand name.

Google founders Page and Brin had cunningly given the name Alphabet to its newly created parent entity, which will specifically house the Google search business along with other smaller holding. Among the smaller holding, the most important ones are Nest, which is a maker of smart thermostats, Calico, which is focused on longevity and a division, which focuses on developing smart contact lenses and driverless cars.

A lot of firms use Alphabet in their names

Alphabet is rather a common name, which finds itself in many derivates and moderations among the companies listed in US and worldwide. Within US there are 103 trademark registered which includes the word Alphabet or in some other variations as per the database with U.S. Patent and Trademark Office. These registrations had been done by companies coming from various fields such as computer games, furniture, clothing label, books, toys, children accessories makers and others.

On Wall Street, there is a company which goes by name Alphabet Funds. Another company Alphabet Energy in Hayward, an Alphabet Plumbing in Prescott, an Alphabet Record Company in Austin along with numerous inns, restaurants and preschools using Alphabet in its name with different variations.

Conflicts might arise with Google’s Alphabet

BMW a premier carmaker already has a robust subsidiary car division named Alphabet, which manages the fleet management at BMW. On a good note, it already possesses the premium domain name alphabet.com. There are chances of Google finding itself broiled into trademark infringement by using the same name and providing similar kind of services to the end users. Since Google is not going to offer similar goods and services there is no likelihood of creating confusion among the consumers at the moment.

Larry Page envisions a separate road for Alphabet

During the announcement, Google CEO Larry Page had made it clear that the new parent company namely Alphabet is not intended for creating a big consumer brand with related products rather it will provide the independence in creating and developing their own brands. Regarding the choosing of name Page emphasized that alphabet actively represents a language and it even signifies “core of how we index” in a Google Internet search.

A history getting into troubles

Google had even experienced legal over intellectual property in the past. Google is frequently targeted by the companies, which claim it off aggressively violating their patents. Currently Google is handling a severe copyright battle with the Oracle Corp exclusively over the royalties, which are used in the Java programming language and being used by Google in its Android operating system.

Deep Neural Nets Can Now Recognize Your Face in Thermal Images

Neural Network – Connecting Mid-or-Far Infrared Image

Cross modal matching of the face between thermal and visible range is a desired capability especially during night time scrutiny as well as security applications. Owing to huge modality gap, thermal to visible recognition of the face seems to be one of the challenging face matching issue.

Recently Saquib Sarfraz and Rainer Stiefelhagen at Karlsruhe Institute of Technology in Germany has worked out for the first time, a way in connecting a mid-or far-infrared image of a face with a visible light counterpart, a trick they have achieved in teaching a neural network to do all the task. Corresponding to an infrared image of a face to its visible light counterpart is not an easy work, but which deep neural networks are beginning to surface.

The issue with infrared observed videos or infrared CCTV images is that it could be difficult in recognising individuals where the faces tend to look different in the infrared images. Matching of these images to their usual look could be an important uncertain experiment. The issue could be that the connection between the way one may tend to look in infrared and visible light could be very nonlinear. This could be very complicating for footage which could be taken in midand far-infrared that could use passive sensors detecting emitted light instead of the reflected range.

Visible Light Images- High Resolution/Infrared Images – Low Resolution

The way in which a face emits infrared light is completely different from the way it reflects it where the emissions differ as per the temperature of the air as well as that of the skin. This in turn is based on the activity level of the individual, like having a fever or not. Another issue which could make comparison difficult is that visible light images could have a high resolution while far infrared images could have a much lower resolution due to the nature of the camera from which the images have been taken.

Collectively, these factors could tend to make it difficult in matching an infrared face with its visible light corresponding image. With the recent developments in deep neural networks in overcoming all types of difficult issues, it gave rise to the idea to Sarfraz and Stiefelhagen. They speculated on training a network to recognize visible light faces by looking at infrared types. Two major factors have been pooled in, recently in making neural networks very powerful.

Better Understanding/Availability of Interpreted Datasets

Better understanding, being the first, on how to build and tweak the networks in the performance of their task which is a procedure leading to the development of the supposed deep neural nets which was something that Sarfraz and Stiefelhagen learnt from other work.The second is the availability of largely interpreted datasets which could be utilised in training these networks.

For instance accurate computerized face recognition has been possible due to the creation of massive banks of images wherein people’s faces have been remote as well as identified by observers because of crowdsourcing services like Amazon’s Mechanical Turk. These data sets seem to be much difficult to come by for infrared or visible light evaluations.

Nevertheless, Sarfrax and Stiefelhagenhandled this issue. It was created at the University of Notre Dame comprising of 4,585 images of 82 individuals which were taken either in visible light at a resolution of 1600 x 1200 pixels or in the far infrared at 312 x 239 pixels.The data is said to comprise of images of individuals, laughing, smiling together with neutral expressions taken in various sessions in order to capture the way their appearance seem to change from day to day and in two various lighting conditions.

Fast/Capable of Running in Real Time

Each image was then divided into sets of overlapping patches of 20 x 20 pixels in size in order to vividly increase the size of the database. Eventually Sarfraz and Stiefelhagen utilised the images of the first 41 individuals in training their neural net together with the images of the other 41 people for the purpose of testing. The outcome of it seemed to be interesting.

Sarfraz and Stiefelhagen have commented saying that `the presented approach improves the state-of-the art by more than 10 percent. It is said that the net can now match a thermal image to its noticeable counterpart in a mere 35 milliseconds. They further added that `this is very fast as well as capable of running in real time at ∼ 28 fps’. Though it is by no means flawless, at best its precision is over 80 percent when it has anextensivearray of visible images when compared against the thermal image.

The one-to-one contrast accuracy is only 55 percent. Improved accuracy could be possible with larger datasets together with much more powerful network, out of which, the creation of a data set that is higher by order of magnitude would be the more difficult of the two jobs.

However, it is not an issue to imagine this type of database to be created rather quickly provided the interested individuals could be the military, law enforcement agencies and government who tend to have deeper pockets with regards to security related technology.
