However, because the modeling environment of Simulink is a mixed and heterogeneous one as the combinations of discrete semantics, continuous semantics, etc. Usually it is not very easy to understand a Simulink model. A better way to represent a Simulink model may be necessary. One possible method is to separate the model into sub-models which have relatively simpler, well-defined semantics. Wit...

Social media exists and has become a part of human life. The presence the internet its development brings new ways communicating in social presents changes paradigm communication today's society. Communication is not limited by distance, time space. It can happen anywhere, anytime, without having to meet face face. Even seem negate status which often becomes barrier communication.

Different countries, where considered be foreign language, are emphasizing developing language learning teaching strategies the status of globalization. To achieve this goal, speaking skills play crucial role as it effective mode communication connect with world. This created immense n...

Parallel computing has turned out to be the enabling technology to solve complex physical systems. However, the transition from shared memory, vector computers to massively parallel, distributed memory systems and, recently, to hybrid systems poses new challenges to the scientist. We want to present a cook-book (with a very strong, personal bias) based on our experience with parallization of ou...

Trials to develop a CORBA toolkit have been made at DESY and KEK. This toolkit provides basic APIs for general-purpose data exchange. There are two aims of the trials. The first one is to make it easier to convert the existing CORBA applications of older versions (Digital’s @aGlance) to those with the new CORBA environment (Object Broker). Since the toolkit includes a complete emulation of the ...

Data mining plays an important role in obtaining and analysing the useful information from databases. Mobile computing and cloud computing can be combine together to overcome the limitations of mobile phones while overcoming the communication overhead. Development of location based application becomes easier because of smartphones. A lots of information is been collected from these applications...

Wireless networks now enjoy widespread commercial implementation because of their ease of use, low cost and setup. However, since accessing wireless media is much easier than tapping a wired network, then security becomes a serious concern when implementing any wireless network. We consider a particular class of Denial of Service (DoS) attacks called jamming attacks. In the simplest form of jam...
