During the last years, Intelligent Virtual Environments for Training have become a quite popular application of computer science to education. These systems involve very different technologies, ranging from computer graphics to artificial intelligence. However, little attention has been paid to software engineering issues, and most of these systems are developed in an ad-hoc way that doesn't al...

The explosion of the web has led to a situation where a majority of the traffic on the Internet is web related. Today, practically all of the popular web sites are served from single locations. This necessitates frequent long distance network transfers of data (potentially repeatedly) which results in a high response time for users, and is wasteful of the available network bandwidth. Moreover, ...

Distributed blackboard is one of the popular agent communication architectures. However, in current agent systems, the distributed blackboard architecture is kept fixed after its initial setting, which may influence the system performance when network topology or agent cooperation relations are changed during operation. To solve the problem, this paper presents a novel mechanism for adjusting a...

Networked multiplayer video games have become enormously popular over the past two decades. Recently the capabilities of traditionally-designed game servers have begun to be outstripped by the demands of vast numbers of players, motivating re-thinking of the fundamental server design. This project proposes a novel architecture for highly scalable networked multiplayer games, and examines the po...

The neural network is popular and used in many areas within the financial field, such as credit authorization screenings, regularities in security price movements, simulations of market behaviour, and so forth. In this research, the authors use a neural network technique for stock price forecasting of Great West Life, an insurance company based in Winnipeg, Canada. The Backpropagation algorithm...

Mobility in Peer-to-Peer (P2P) networking has become a popular research area in recent years. One of the new ideas has been how P2P would suit for cellular networks. In this case, Mobile Peer-to-Peer (MP2P) presents not only technical but also business and legal challenges. The current 2G cellular networks cannot successfully support MP2P applications but the forthcoming 3G and WLAN networks of...

Google Maps and Google Earth are very popular web mapping services but they are not open and not OGC-compliant. The question arises why this is not the case. One reason is that commercial data providers require a tight coupling between the provided maps and additional supplements like advertisements. Another answer to this question is the missing support of mashups that become more and more pop...

Network security has always been a significant issue, but a recognized priority today due to the popular of internet. The issue is not if security should be implemented on a network; rather, the question to ask is if security has been implemented properly and the interoperability with today’s network architecture. Although there are various ways to perform a secure network environment, but the ...

Most of the organizations are still predicated on the client server paradigm. Major crack of these systems is inflexibility regarding to extension and habituating changes. As the IT developing, customer’s demand changes dynamically. Therefore, the enterprise should have systems that are able to adapt new business scenarios. To fulfill this requisite, Service Oriented Architecture (SOA) is come ...

A pipeline is a popular architecture which connects computational components (filters) through connectors (pipes) so that computations are performed in a stream like fashion. The data are transported through the pipes between filters, gradually transforming inputs to outputs. This kind of stream processing has been made popular through UNIX pipes that serially connect independent components for...
