ALVIC versus the Internet: Redesigning a Networked Virtual Environment Architecture  [PDF]
Peter Quax,Jeroen Dierckx,Bart Cornelissen,Wim Lamotte
International Journal of Computer Games Technology , 2008, DOI: 10.1155/2008/594313
Abstract: The explosive growth of the number of applications based on networked virtual environment technology, both games and virtual communities, shows that these types of applications have become commonplace in a short period of time. However, from a research point of view, the inherent weaknesses in their architectures are quickly exposed. The Architecture for Large-Scale Virtual Interactive Communities (ALVICs) was originally developed to serve as a generic framework to deploy networked virtual environment applications on the Internet. While it has been shown to effectively scale to the numbers originally put forward, our findings have shown that, on a real-life network, such as the Internet, several drawbacks will not be overcome in the near future. It is, therefore, that we have recently started with the development of ALVIC-NG, which, while incorporating the findings from our previous research, makes several improvements on the original version, making it suitable for deployment on the Internet as it exists today.

International Journal of Computer Technology and Applications , 2012,
Abstract: We use the decimal code to represent numbers. Digital electronic circuits in computers and calculators use general the binary code to represents numbers. A common task of decoding from machine language to decimal numbers is encoding. A very common output device to display decimal numbers is the seven segment display. In this research paper we have formulated how experiments on 7-Segment display are performed using the concept of virtual Intelligent SoftLab (VIS). A 7-Segment display constructed using the Virtual SoftLab and observed actual outputs. The 10 (ten) digits (0-9) are represented by 4-bit input. VIS helps us to create results using visual display. Software for conducting the experimentations in 7-Segment display has been developed which helps students to perform and practice the experiments. A 7-Segment display experiments provides a pictorial method of design and evaluating experiments. In this paper we have designed the software that can observe the results. This will help students in understanding working of 7-Segment display

International Journal of Engineering Sciences & Research Technology , 2013,
Abstract: The progressive increase in number of components and electronic system demands the overall architecture to be developed in different scenario .In order to achieve optimum electronic systems, it is necessary to build many real devices and evaluate the performance of systems. However, it is also becoming necessary to build virtual devices because of the increasingly complicated and large-scale systems. So the physical level, connecting between functional level and implementation level, should also be applied to virtual development. On the other hand, not only the functions, but also the safety designs need virtual technology to apply fault injection. With increasingly sophisticated ECU development technologies, static simulators can no longer work with requisite testing requirements, so dynamic simulators are preferred. This progression with dynamic simulator will discusses the overall architecture of the system and the design decisions are made to reduce system cost. This paper also discusses a concept and a powerful tool, which allows a wide range of automatic tests to be performed on networked ECUs. More precisely, it represents a complex system for connecting and testing all the networked ECUs in a modern vehicle. Basically, testing is a vital and on-going part of the product development process, especially in the development of automotive systems. Validation testing of vehicle electrical systems and their computation is difficult and thus, expanding with the growth of certain features. Thus, a key to reduce test costs in increasingly complex systems is to work with the ability of the requisite distribution process in order to make every testable component in simpler manner
