The crossbar is very popular for the implementation of switches with a moderate number of ports. Unbuffered crossbars (IQ architecture) require complex switch matrix scheduling algorithms that operate on fixed-size cells. On the other hand, buffered crossbars (CICQ architecture), use small buffers at the crosspoints and provide excellent features; scheduling is simplified and variable-size pack...

Multi-server architecture is very popular in Distributed Virtual Environments. Although multi-server architecture has good scalability, the load balance and consistency are still challenging issues. Because of server resource limitations (computation, communication etc), the consistency of the virtual world cannot be guaranteed sometimes. In this paper, we address this problem by developing sch...

Our group has been developing medical image software systems since the early 1980s. Our latest system, CAVASS, is freely available, open source, integrated with popular toolkits, and runs on Windows, Unix, Linux, and Mac OS. The architecture of CAVASS incorporates parallel processing by exploiting inexpensive networks of workstations. CAVASS is directed at the visualization, processing, and ana...

The recent success of social networking sites like mySpace, Friendster, Orkut, LinkedIn, Ecademy and openBC indicates that extending one's social network through a virtual medium is a popular proposition. The social networking paradigm can be integrated with the knowledge management field, in which sharing knowledge with others is a central issue. This paper investigates how the social networki...

Games and video games entertain us and allow us to socialize and learn. Trying to take advantage of the interest in them and their characteristics as tools for education, the development of Serious Games has become popular. This paper presents the GAMeNT Framework which consists of an architecture and a methodology that guide the design and development of Serious Games. This framework was devel...

As mobile devices have been popular, many wireless applications for mobile devices have been developed. The paper presents the financial transaction system for online game and its architecture in J2EE. The system provides transactional report by filtering the millions of transactions on selected periods. The paper first describes the system’s financial transaction formula, then, provides m-Comm...

In this paper, we design a real time estimation system in complex system simulation research. The popular simulation technology High Level Architecture (HLA) is introduced. The logical structure of the system is constructed with three levels of data resource, component and application. The main functions of the system are given, including sample collection, real time estimation, result display,...

This paper introduces a novel architecture for reinforcement learning with deep neural networks designed to handle state and action spaces characterized by natural language, as found in text-based games. Termed a deep reinforcement relevance network (DRRN), the architecture represents action and state spaces with separate embedding vectors, which are combined with an interaction function to app...

Since 1994, active networks have become a popular research field. Under the motivation of technology “push” and user “pull”, we would like to purpose new active networks architecture that is secure, safe, efficient and flexible. Before we introduce new active networks architecture, the complete survey is an important milestone. In this report, we try to clearly describe the concept of active ne...

Nowadays, new forms of virtual architecture are appearing as virtual worlds based on the Metaverse concept are becoming increasingly more popular, holding all kind of virtual versions of human activities. This paper aims to make a reflection on the features of these new architectures compared with their equivalents in the real world by means of an analysis through the prism of the three fundame...
