The TCP congestion control protocol is mainly designed for bandwidth symmetric paths. As two-way asymmetric connections will probably become common case in the future with the widespread use of ADSL, satellites and other high-speed technologies, it is important to make sure that congestion will be properly handled in these environments. To this end, we propose in this paper a new Adaptive Class...

This paper presents a congestion management methodology in deregulated power systems by making use of optimal placement of thyristor controlled series compensators (TCSCs) in transmission network. The problem formulation consists of maximization of social welfare function subject to real and reactive power balance, constant power factor of consumers, transmission congestion (line loading), gene...

A principle task in parallel and distributed systems is to reduce the communication load in the interconnection network, as this is usually the major bottleneck for the performance of distributed applications. In this paper we introduce a framework for solving on-line problems that aim to minimize the congestion (i.e. the maximum load of a network link) in general topology networks. We apply th...

Reservationless computer communication networks based on the best effort paradigm are no longer capable of providing the quality of service necessary for the new generation of computer communication services, such as voice, video and multimedia services. These new services and their users have very different communication needs, and must not be treated equal by the communication system. Quality...

In the deregulated power systems, transmission congestion is one of the significant and main problems of the electrical networks which can cause incremental cost in the energy. This problem has resulted to new challenging issues in different parts of power systems which there was not in the traditional systems or at least had very little importance. Transmission congestion happens when the maxi...

If your neighborhood has cable TV service, you may have been tempted by the idea of a cable modem. These ingenious devices connect you to the Internet over your cable line, 24 hours a day, 7 days a week. Unlike the standard modems in use since the 1980s, a cable modem leaves your phone line free. Unfortunately, few technological advances come without a cost. In the case of cable modems, consume...

The sweep-line state space method allows states to be deleted from memory during state exploration, thus alleviating state explosion. Properties of the system (such as the absence of deadlocks) can then be verified on-the-fly. This paper presents an extension to the sweepline method that allows on-the-fly checking of language inclusion, which is useful for protocol verification. This has been i...

We propose a traffic congestion estimation system based on unsupervised on-line learning algorithm. The system does not rely on background extraction or motion detection. It extracts local features inside detection regions of variable size which are drawn on lanes in advance. The extracted features are then clustered into two classes using K-means and Gaussian Mixture Models(GMM). A Bayes class...
