Now a days, there is demanding needs of developing interactive mediums of study. As our conventional methods of learning are not very effective. programming has become one of the core subjects of every field of study due to their vast use. However, introducing computer programming to those students who's are not familiar with programming is a tough task. Use interactive learning through visual effects using AR (Augmented Reality) developed to provide a platform for new students to interact more in learning environment. As this learning environment becomes more effective it is easier for new comers to understand key concepts of programming more effective way.

The application of standard Intel processor based personal computers and the Windows operating system is a trend that cannot be ignored. An integrated PC card is described which extends NC controllers with new feature: network communication, floppy disk and hard disk and flash drive. PC and NC unit communicate by using dual port memory, which has two sets of address, data and read/write control signals, each of them access the same set of memory cells.

Constructivism ensures the survival of computer science graduates in the industry. According to Moore's Law, the number of active devices that can be placed over a given area of silicon doubles every 18 months. It is becoming a known fact that the existing computerised systems may become obsolete even before a user has completed his training to fully utilising the former. The pace at which computing technologies are evolving today knows no bound. Recently, IBM created a graphene-based transistor which operates over twice the speed of silicon chips. New sets of solutions need to be devised (a) to optimise the use of new hardware capabilities and (b) to cater the emerging issues. Computer science students need to be given the appropriate tools, together with a probing mindset, to develop self capacity-building and tackle emerging problems. This paper highlights the constructivist's approaches to teaching computing subjects at the tertiary level to develop the inquisitive minds of prospective computer scientists.

Wirth's proposal for type extensions includes an algorithm for determining whether a given value belongs to an extension of a given type. In the worst case, this algorithm takes time proportional to the depth of the type-extension hierarchy. Wirth describes the loop in this algorithm as "unavoidable," but in fact, the test can be performed in constant time by associating a "display" of base types with each type descriptor.

Above all, it is vital to recognize that completely guranteed behavior is impossible and that there are inherent risks in relying on computer systems in critical environments. The unforeseen consequences are often the most disastrous [Neumann 1986]. Section 1 of this survey reviews the current state of the art of system reliability, safety, and fault tolerance. The emphasis is on the contribution of software to these areas. Section 2 reviews current approaches to software fault tolerance. It discusses why some of the assumptions underlying hardware fault tolerance do not hold for software. It argues that the current software fault tolerance techniques are more accurately thought of as delayed debugging than as fault tolerance. It goes on to show that in providing both backtracking and executable specifications, logic programming offers most of the tools currently used in software fault tolerance. Section 3 presents a generalization of the recovery block approach to software fault tolerance, called resourceful systems. Systems are resourceful if they are able to determine whether they have achieved their goals or, if not, to develop and carry out alternate plans. Section 3 develops an approach to designing resourceful systems based upon a functionally rich architecture and an explicit goal orientation.

This paper presents a new conception for a distributed task-oriented real-time operating system comprising a compiler, an operating system kernel and communication packages. The system TOROS supplies the tools for a uniform programming of complex process control applications on heterogenous hardware including workstation, PC, programmable controller and micro controller. The whole control task is split into a set of small modules. These modules are uniquely programmed by defining a state machine and using guarded commands. They are connected logically through calls to tasks provided by other modules. The specification of the modules is done in an hardware independent language. At compile time the modules are distributed to specified target computers. The system automatically translates each module into the particular code and realizes the communication between the modules either on the same computer or through the links.

With the surge of popularity of PHP 5, and with PHP 6 just around the corner, object-oriented programming is now an important consideration for PHP developers. This version-neutral book is a gentle introduction to object-oriented programming (OOP) that wont overburden you with complex theory. It teaches you the essential basics of OOP that youll need to know before moving onto a more advanced level, and includes a series of pre-packaged scripts that you can incorporate into your existing sites with the minimum of effort. It shows how OOP can be used to create reusable and portable code by walking you through a series of simple projects. The projects feature the sorts of things developers run up against every day, and include a validator for filtering user input, a simple Date class that avoids the need to remember all the esoteric format codes in PHP, and an XML generator. Teaches the fundamentals of OOP Simple projects show how OOP concepts work in the real world Pre-packaged scripts can easily be added to your own projects What youll learn PHP features, such as the Standard PHP Library (SPL), that are poorly documented or ignored by existing books How to develop classes of their own OOP in easy-to-understand language without getting bogged down in dense theory Solid foundations for developers wishing to delve more deeply into OOP How to leverage the strengths of OOP as a means for creating reusable code that can be used successfully within a procedural context How to code for both PHP 5 and 6 Who is this book for? This book is aimed at intermediate-level PHP developers who want to take their skills to the next level by exploring object-oriented programming as a way of creating reusable code for a everyday website tasks. A typical reader would be someone who has read one of the authors previous title, such as PHP Solutions, or one of the PHP books for Dreamweaverand feels ready to tackle something a little more challenging.

The definition of the second major release of the Unified Modelling Language, or UML 2.0, has been a long process. But the latest version of the object Management Group (OMG) standard will soon be ready. The large number of changes between UML 1.x and UML 2.0 have raised concerns from users: what is new in UML 2.0? Should I migrate? Is it compatible with existing UML 1.x?

Although Ruby is an easy language to learn, in the heat of action you may find that you can't remember the correct syntax for a conditional or the name of a method. This handy pocket reference offers brief yet clear explanations of Ruby's core components, from operators to reserved words to data structures to method syntax, highlighting those key features that you'll likely use every day when coding Ruby. Whether you've come to Ruby because of the Rails web development framework --Ruby's killer app -- or simply because it's a relatively clean, powerful and expressive language that's useful for a lot of applications, the Ruby Pocket Reference is organized to help you find what you need quickly. This book not only will get you up to speed on how Ruby works, it provides you with a handy reference you can use anywhere, anytime. In this book, you find essential information on: Reserved words, operators, comments, numbers, variables, ranges, and symbolsPredefined variables andglobal constantsConditional statements, method use, classes, and modules (mixins)Lists of methods from the object, String, Array, and Hash classes and the Kernel modulesprintf andtime formatting directoriesInteractive Ruby (irb) and the Ruby debuggerRuby documentation You also get information on the RubyGems package utility and Rake, a build tool similar to make..
