Artificial Intelligence
Artificial intelligence (AI) is the intelligence exhibited by machines or software. It is also the name of the academic field of study which studies how to create computers and computer software that are capable of intelligent behavior. Major AI researchers and textbooks define this field as "the study and design of intelligent agents", in which an intelligent agent is a system that perceives its environment and takes actions that maximize its chances of success. John McCarthy, who coined the term in 1955, defines it as "the science and engineering of making intelligent machines".
AI research is highly technical and specialized, and is deeply divided into subfields that often fail to communicate with each other. Some of the division is due to social and cultural factors: subfields have grown up around particular institutions and the work of individual researchers. AI research is also divided by several technical issues. Some subfields focus on the solution of specific problems. Others focus on one of several possible approaches or on the use of a particular tool or towards the accomplishment of particular applications.
The central problems (or goals) of AI research include reasoning, knowledge, planning, learning, natural language processing (communication), perception and the ability to move and manipulate objects.General intelligence is still among the field's long-term goals.Currently popular approaches include statistical methods, computational intelligence and traditional symbolic AI. There are a large number of tools used in AI, including versions of search and mathematical optimization, logic, methods based on probability and economics, and many others. The AI field is interdisciplinary, in which a number of sciences and professions converge, including computer science, mathematics, psychology, linguistics, philosophy and neuroscience, as well as other specialized fields such as artificial psychology.

Windows 8
Windows 8 is a personal computer operating system developed by Microsoft as part of the Windows NT family of operating systems. Development of Windows 8 started before the release of its predecessor, Windows 7, in 2009. It was announced at CES 2011, and followed by the release of three pre-release versions from September 2011 to May 2012. The operating system was released to manufacturing on August 1, 2012, and was released for general availability on October 26, 2012.
New and changed features
Language and standards support
Windows 8 introduces the new Windows Runtime (WinRT) platform, which can be used to create a new type of application officially known as Windows Store apps and commonly called Metro-style apps. Such apps run within a secure sandbox, share data with other apps through common APIs. WinRT, being a COM-based API, allows for the use of various programming languages to code apps, including C++, C++/CX, C#, Visual Basic .NET, or HTML5 and JavaScript.
Apps in Windows 8 may snap to the side of a widescreen display to allow multi-tasking, forming a sidebar. In Windows 8.1, the size of this sidebar can be changed. Snapped apps may occupy half of the screen. Large screens allow up to four apps to be snapped. Upon launching an app, Windows allows the user to pick which snapped view the app should open into.
The term "Metro-style apps" referred to "Metro", a design language prominently used by Windows 8 and other recent Microsoft products. Reports surfaced that Microsoft employees were told to stop using the term due to potential trademark issues with an unspecified partner. A Microsoft spokesperson however, denied these reports and stated that "Metro-style" was merely a code name for the new application platform.
Windows 8.1 introduces Assigned Access, formerly called Kiosk mode, which restricts the Windows device to a running a single predetermined Metro-style app.
Windows 8 also introduces APIs to support near field communication (NFC) on Windows 8 devices, allowing functionality like launching URLs/applications and sharing of information between devices via NFC.
Windows Store
Windows Store is a digital distribution platform built into Windows 8, which in a manner similar to Apple's App Store and Google Play, allows for the distribution and purchase of apps designed for Windows 8. Developers will still be able to advertise desktop software through Windows Store as well. To ensure that they are secure and of a high quality, Windows Store will be the only means of distributing WinRT-based apps for consumer-oriented versions of Windows 8.
In Windows 8.1, Windows Store features a redesigned interface with improved app discovery and recommendations and offers automatic updates for apps.

Know about Scilab...........
What is Scilab ..??
Scilab is an open source, cross-platform numerical computational package and a high-level, numerically oriented programming language. It can be used for signal processing, statistical analysis, image enhancement, fluid dynamicssimulations, numerical optimization, and modeling, simulation of explicit and implicit dynamical systems and (if the corresponding toolbox is installed) symbolic manipulations. MATLAB code, which is similar in syntax, can be converted to Scilab. Scilab is one of several open source alternatives to MATLAB.
Scilab is a high-level, numerically oriented programming language. The language provides an interpreted programming environment, with matrices as the main data type. By using matrix-based computation, dynamic typing, andautomatic memory management, many numerical problems may be expressed in a reduced number of code lines, as compared to similar solutions using traditional languages, such as Fortran, C, or C++. This allows users to rapidly construct models for a range of mathematical problems. While the language provides simple matrix operations such as multiplication, the Scilab package also provides a library of high-level operations such as correlation and complex multidimensional arithmetic. The software can be used for signal processing, statistical analysis, image enhancement, fluid dynamics simulations, and numerical optimization.
Scilab also includes a free package called Xcos (based on Scicos) for modeling and simulation of explicit and implicit dynamical systems, including both continuous and discrete sub-systems. Xcos can be compared to Simulink fromthe MathWorks.
As the syntax of Scilab is similar to MATLAB, Scilab includes a source code translator for assisting the conversion of code from MATLAB to Scilab. Scilab is available free of cost under an open source license. Due to the open source nature of the software, some user contributions have been integrated into the main program.
What does Scilab do ?
Scilab includes hundreds of mathematical functions. It has a high level programming language allowing access to advanced data structures, 2-D and 3-D graphical functions.
A large number of functionalities is included in Scilab:
- Maths & Simulation

Scilab as a platform
Thanks to its ability to interconnect with third-party technologies andapplications, Scilab can also act as a unique platform to bring together codes written in different programming languages in a single, unified language, thus facilitating their distribution, their back-up and use.
Why is it free ?
Because Scilab is open source
A entire community of contributors participates to the development of Scilab, from contribution to the code, development of external modules to the localization. The international scientific community, both academic and industrial spheres, invests in Scilab to gather recent scientific breakthroughs in the field of numerical computation.
Because Scilab is funded by Scilab Enterprises
Scilab Enterprises is the publisher and professional services provider of Scilab. Industrial companies benefit directly from this expertise to get the solution suited to their needs through a comprehensive range of support, migration, development services and the implementation of specific applications.

Know about Latex......
What is LateX...?
LaTeX is a document markup language and document preparation system for the TeX typesetting program. The term LaTeX refers only to the language in which documents are written, not to the editor application used to write those documents. In order to create a document in LaTeX, a .tex file must be created using some form of text editor. While most text editors can be used to create a LaTeX document, a number of editors have been created specifically for working with LaTeX.
LaTeX is widely used in academia. It is also used as the primary method of displaying formulas on Wikipedia. As a primary or intermediate format, e.g., translating DocBook and other XML-based formats to PDF, LaTeX is used because of the high quality of typesetting achievable by TeX. The typesetting system offers programmable desktop publishing features and extensive facilities for automating most aspects of typesetting and desktop publishing, including numbering and cross-referencing, tables and figures, page layout and bibliographies.
LaTeX is intended to provide a high-level language that accesses the power of TeX. LaTeX essentially comprises a collection of TeX macros and a program to process LaTeX documents. Because the TeX formatting commands are very low-level, it is usually much simpler for end-users to use LaTeX.
To produce this in most typesetting or word-processing systems, the author would have to decide what layout to use, so would select (say) 18pt Times Roman for the title, 12pt Times Italic for the name, and so on. This has two results: authors wasting their time with designs; and a lot of badly designed documents!
LaTeX is based on the idea that it is better to leave document design to document designers, and to let authors get on with writing documents. So, in LaTeX you would input this document as:
\documentclass{article} \title{Cartesian closed categories and the price of eggs} \author{Jane Doe} \date{September 1994} \begin{document} \maketitle Hello world! \end{document}
LaTeX contains features for:
- Typesetting journal articles, technical reports, books, and slide presentations.
- Control over large documents containing sectioning, cross-references, tables and figures.
- Typesetting of complex mathematical formulas.
- Advanced typesetting of mathematics with AMS-LaTeX.
- Automatic generation of bibliographies and indexes.
- Multi-lingual typesetting.
- Inclusion of artwork, and process or spot colour.
- Using PostScript or Metafont fonts
