The rapid development of P2P technologies and appearing scope of applications involving it will help to solve a lot of optimization problems and improve the QoS for data delivery services. This paper is an extension of previous papers devoted to modelling P2P media streaming service and describes the design and simulation software architecture of P2P streaming network with buffering mechanism f...

Power ultrasonic reactors have gained a lot of interest in the food industry given the effects that can arise from sound induced cavitation. However, most of the new food processing developments have been based on empirical approaches. Thus, there is a need for mathematical models which help to understand, optimise and scale up ultrasonic reactors. In this work, a CFD model has been developed, ...

In Austria like in many other countries nearly all school have an internet connection. This offers a lot of new possibilities in communication and information retrieval. The authors believe that streaming and broadcasting technology which require broadband access will lead to a major step forward in the use of IT in classroom. The prime aim of the AVD project is to investigate the potentialitie...

Usually, a streaming algorithm is used in scenarios in which there are a lot of data (items) arriving and there is a space or time limitation for storage of data and processing later. More precisely, streaming algorithms are on-line algorithms which process the data streams. Each data stream is a long sequence of items arriving rapidly, denoted by I1, I2, ..., It, ..., Im where It is the t th i...

Lot streaming, is an effective technique to increase production efficiency in a productive system by splitting job into several smaller parts overlap operations between successive machines multi-stage system. In this paper, hybrid flow shop scheduling problem with lot learning effect and buffer's limitation considered. A bi-objective mathematical model presented for minimizing the total tardine...

Video streaming over peer-to-peer networks has attracted a lot of interest recently. However most of the research on streaming in peer-to-peer networks focused on schemes where all the clients have the whole movie. In this paper we propose schemes where clients store only partial movie after viewing the movie. We propose cooperative schemes where replication is done in a way that maximizes a gl...

Multirate multimedia delivery applications in multihop Wireless Mesh Network (WMN) are data redundant and delay-sensitive, which brings a lot of challenges for designing efficient transmission systems. In this paper, we propose a new cross layer resource allocation scheme to minimize the receiver side distortion within the delay bound requirements, by exploring application layer Position and Va...

Adaptive streaming has become a key technology for various multimedia services, such as online learning, mobile streaming, Internet TV, etc. However, because of throughput fluctuations, video quality may be dramatically varying during session. In addition, stalling events occur when segments do not reach the user device before their playback deadlines. It is well-known that variations and cause...
