This paper is a report of new musical instrument/ interface in which the main concept is "untouchable". I will report on not only the system design but also on the performances as applications. The new musical instrument/interface is constructed with infrared rays distance sensors and optical distance sensors. In attending some concerts of computer music in the past, I was inspired with perform...

In the intelligent transportation systems, many applications and services could be offered in the road via Internet. Providing these applications over vehicular ad hoc network (VANETs) technology may require good performances in routing. The channel fading and quality of received signal are the two main factors which affect the Mobile ad hoc network performances as well as mobility of vehicles,...

Multihop relaying is one of the promising techniques in future generation wireless networks. The adaptive modulation and coding (AMC) mechanisms can be applied in order to increase the spectral efficiency of wireless multihop networks. However, most of these mechanisms concentrate on the physical layer without taking the queuing effects at the data link layer into account, whose performances ar...

It has become necessary to monitor the change in learners' skills during education carried out electronic environments. In this study, pre-service teachers made a presentation their teaching practice, and formative assessment was given ensure active participation of observer online peer process. The were asked evaluate peers' performances using rubric. Based on quantitative data collected analy...

tourism, combined with the phrase medical, seems to be a new form of tourism which has gained huge popularity in recent decades. though, a number of literatures available with regard to the tourism industry and the competitiveness of the destination, however, the major aspects which determine the satisfaction of medical tourists are hardly focused specifically on malaysia. there is a lack of em...

in this paper the design and implementation of fault tolerable architecture for scientific workflow engines is presented. the engines are assumed to be implemented as composite web services. current architectures for workflow engines do not make any considerations for substituting faulty web services with correct ones at run time. the difficulty is to rollback the execution state of the workflo...

This manuscript introduces a novel design concept for advanced mobile terminals with radio network aggregation capability and enhanced Quality of Service (QoS) provisioning for various multimedia services in heterogeneous wireless and mobile networks. We establish a new module that provides the best QoS and lowest cost for any given multimedia service (voice, video and audio) by using simultane...

Video on Demand (VoD) services are very appealing these days. In this work, we discuss four distinct alternatives for the architecture of a VoD server and compare their performances under different conditions. We later used the best configuration found in our analysis to evaluate, using simulations, the performance of a distributed VoD service in an ATM network covering an area the size of a la...
