This paper describes the design and implementation of a hybrid intelligent surveillance system consisting of an embedded system and a personal computer (PC)-based system. The embedded system performs some of the image processing tasks and sends the processed data to a PC. The PC tracks persons and recognizes two-person interactions by using a grayscale side-view image sequence captured by a sta...

Many applications have stimulated the recent surge of interest single-chip parallel processing. In such machines, it is crucial to implement a high-throughput low-latency interconnection network to connect the on-chip components, especially the processing units and the memory units. In this paper, we propose a new mesh of trees (MoT) implementation of the interconnection network and evaluate it...

The increasing demand for Software Engineering professionals, particularly Project Managers, and popularization of the Web as a catalyst of human relations have made this platform interesting for training this type of professional. The authors have observed the widespread use of games as an attractive instrument in the process of teaching and learning. However, the project of a web-based instru...

The Tropos project was launched in the Spring of 2000. Its aim has been to establish a methodology for building agent-oriented software systems. The methodology that has emerged is founded on the i* modelling framework to support four phases of software development: early and late requirements, as well as architectural and detailed design. The purpose of this report is to offer an overview of o...

The Experimental Physics and Industrial Control System (EPICS) requires expensive hardware and software to provide the high performance and high reliability required for accelerator control. No more than several years ago, personal computers based on Intel x86 microprocessors lacked computing power to compete with workstations, such as SPARCstation. However, with the advent of the high performa...

The purpose of our research is the development of a new technology, teleimmersion, which will make possible 3D visual communication between people distributed over the globe. We are putting together a low-end, PC-based, affordable hardware system, and are developing the software for a teleimmersion node (T-node). The software is based on accurate polynocular stereo. We will describe a testbed f...

Due to advances in computer architecture, performance of the PC now exceeds that of the typical mainframe. However, computing cost on a mainframe continues to greatly exceed that on a PC. Thus, migrating mainframe applications to PC can result in substantial savings. The major stumbling block in doing this is the cost of software migration itself. This paper discusses an experiment in using a s...

ARM® is the prevalent processor architecture for embedded and mobile applications. For the smartphones, it is the processor for which software applications are running, whether the platform is with Apple’s iOS or Google’s Android. Software operations under these platforms are prone to semantic gap, which refers to potential difference between intended operations described in software and actual...
