In terms of facilities for communications and synchronization in parallel programs, the descriptive power of the shared-memory model is equal to that of the message-passing-style (send-and-receive-type) model. From the viewpoint of performance, however,the situation is different. In modern architectures for distributedmemory multicomputers, memory is an important and fundamental building-block ...

The mechatronic design cycle is characterized by taking into account and integrating mechanics, electronics, and information processing in the design process. For complex mechatronic systems a promising procedure is the decomposition of the entire system according to physically reasonable criteria. To describe the function of such combined subsystems we use the expression "mechatronic function"...

In general relativity, it is difficult to localise observables such as energy, angular momentum, or centre of mass in a bounded region. The difficulty that there dissipation. A self-gravitating system, confined by its own gravity region, radiates some the charges away into environment. At formal level, dissipation implies diffeomorphisms are not Hamiltonian. fact, no Hamiltonian on phase space ...

0740-7475/02/$17.00 © 2002 IEEE July–August 2002 NEW MEDIA APPLICATIONS such as highdefinition digital television, set-top boxes with time-shift functionality, 3D games, video conferencing, and MPEG-4 interactivity have generated a demand for increasingly flexible consumer electronics products. These products are evolving into multifunctional devices that combine a set of media applications. Th...

This paper examines methods that can be adopted in early stage or retrofit design of actuator subsystems, and is motivated by the modern trend toward retrofitting legacy hydraulic actuation of submarine control surfaces with electromechanical systems. This problem highlights the familiar need designers have to relate system response requirements to selected subsystems to enable focused developm...

Ubiquitous computing is a hotspot research field at present. The research aboutsmart in-vehicle space is a main domain in ubiquitous computing. As cars play increasinglyimportant role in people’s daily life, smart in-vehicle space has become an essential researchfield in Smart Space. The intelligence of cars is achieved by the cooperation of in-vehicleelectronic systems, which c...
