innInline Group, RSK and Intel are building education “cloud”

“Cloud” education platform is created in North-Ammosov East Federal University (Yakutsk, Sakha Republic) using which each student and professor of the university will receive access to educational resources of the university and new educational services.

Project “United Information Service Space” (UISS) is realized by the Federal University and big Russian IT-integrators: Inline Group and RSK Group supported by Intel Corporation. They have developed general concept of education solution for the University on the base of cloud computing technology. Inline Group was a General constructor being responsible for development of the UISS system project being the basis for the University’s decision, and for realization of hardware and communications of the project. RSK Group takes part in the project as a developer and supplier of innovative education platform “RSK Universum” based on cloud computing to increase quality and effectiveness of teaching in the universities; Intel was an ideologist and consultant because of its broad experience of participation in the similar events all over the world. Realization of the joint project of the University started in November 2011 and now its first stage of launching is being finished.

The students and professors of three departments of our university – Institute of Mathematics and Informatics, Faculty of Biology and Geography, and Physics and Technology Institute - will be the first ones to test the system. Each professor and student will have possibility “to manage his own business” being elsewhere in Sakha, Russia or even world. Thus for example, professors could control a student’s activity and exercises distantly, comment sent materials and documents. It will be possible to check timetables at any time, to know changes of university life or to look through new orders. Also students and professors could share documents and contact with each other virtually.

ComputerwAcer announced its first tetranuclear tablet

Acer Iconia Tab A510 tablet presented by Acer is made with tetranuclear processor and functions with Android 4.0. It has a screen of 10.1 inches with resolution of 1280x800 points. As it is announced in Acer the computer is mainly for games and videos. Acer states that it can function during 12 hours playing videos. Iconia Tab A510 is already presold in North America for 450 USD.

Nvidia Tegra 3 chip is used in the tablet, productivity of which according to the tests of Laptop Magazine is in advance of A5X used in new iPad in some tasks. Till today Acer’s tablets had binuclear processor as maximum. Range of competitors of the company, including Asus, Lenovo etc,  are in advance of it issuing tetranuclear tablets.

Iconia Tab A510 has office package Polaris Office 3.5 which can be matched with files of Microsoft Office format. The tablet also has micro-HDMI and microUSB 2.0 ports, microSD card-reader, 1 Hb of core memory, 32 Gb of flash-memory, megapixels front camera and 5-pixel rear one. It films videos of resolution of 1080p but tablet shows 720p only.

sw_600Microsoft invented how to teach computers to receive gestures in front of the screen

 Miscrosoft Corporation and researchers of University of Washington (USA) developed an application which allows computers to perceive gestures without sensor screen, Kinect controller and other special devices.

Test software was called SoundWave. You need to have just microphone and dynamics. Software generates sound waves of high frequency not heard by a man. The waves are reflected from the objects (for example, user’s hands) at one meter from the emitter and caught by microphone.

System uses Doppler’s principle: changes in characteristics of sound waves are registered and transferred into control commands.

pppQuantum computer D-Wave One hit the market

 Quantum computers creeped from the fantasy world into mass production. Some days ago D-Wave, American company, announced market launch of computer system D-Wave One with Rainer processor.

It’s a very unordinary computer; it can solve the tasks for discrete optimization only. So D-Wave One can be used as a part of any computing clusters for specific aims. It is supposed that the system will be purchased by the companies from Fortune 500 list.

Custer of 128 qubits is used in the quantum Rainer processor, they execute quantum anneal – the quantum system “finds” the most energetically advantageous configuration with quantum fluctuations provided by tunneling through potential barriers.

Thanks to this procedure the computer is more effective for solving tasks in the sphere of discrete optimization (including the ones of combinatory optimization), ordinary computers of binary logics are not designed for this. Thus for example it can be a task of a salesman, for transport rout or diagrams coverage etc.

Specialists are not sure that D-Wave can be called “a real quantum computer” despite the demonstration of coherent quantum effects. The case is that quantum coherence is used in this computer as an auxiliary factor (for quantum anneal) together with ordinary calculations. And “a real quantum computer” shall significantly increase the speed of calculations due to direct operations with qubits.

paDialogue prompts for polysemic queries appeared in Yandex

As the company announced on Wednesday, Yandex, Russian search service, launched dialogue prompts for polysemic queries. Now the users can specify their search if it has several meanings “by one click”.

Thus for example, the system of prompts will help select what the user wants to know exactly if he prints “bog bilberry” in the search box – recipes with this berries or its useful properties. And if you type “Charlie Chaplin” the search service will offer: “Biography? Photo? Video?”

Intent search based on understanding the needs and solving the user’s problems – is one of the basic ways of development of the Russian search service in 2012. The company promises that In the nearest future some more products will be launched.

Dialogue prompts use “Spectrum” technology which was launched in December 2010. Representatives of the company explain: “It determines possible aims of the user and offers the results of search of these aims. “Spectrum” combines answers to different themes in the search results taking into account the demand for them”.

According to Yandex polysemic world and phrases make 20% of new queries. Now in each case the search service will have a dialogue with the user.

Now Gmail users will see an explanation why the letter was refined in the beginning of each message marked as spam. Spam filter can refine the letter for several reasons – dangerous code, fishing threat, marking by users of the same letters as spam etc.

As it is highlighted by Gmail representatives the information can be of interest not for the users only but it could also help them examine fraudulent and dangerous letters from mail box.

According to research of Russian antivirus company “Kaspersky Lab” share of spam in the world mail traffic 2009-2011 decreased for 5% - from 85.2% to 80.26%, but spam became more dangerous because of increased number of viruses in it.
