Structured peer-to-peer (P2P) systems are considered as the next generation application backbone on the Internet. An important problem of these systems is load balancing in the presence of non-uniform data distributions. In this paper we propose a completely decentralized mechanism that in parallel addresses a local and a global load balancing problem: (1) balancing the storage load uniformly a...

The present study was conducted to predict bullying roles over a six years time period and across contexts differing in the degree of peer hierarchies. Out of two representative data sets from primary (N = 1525) and secondary school (N = 2958), 282 children (156 boys; 126 girls) were followed up longitudinally. Self reports on bullying experiences and peer reports about social status were asses...

Service-Oriented Architectures provide integration of and interoptablity for independent and loosely coupled services. Web services and the WSRF standards are frequently used to realise such Service-Oriented Architectures. In such systems, autonomic principles of self-configuration, self-optimisation, self-healing and self-adapting are desirable to ease management and improve robustness. In thi...

The properties of a parallel programming model are largely determined by the model of communication/interaction upon which it is based. Parallel programming models, languages and implementations have historically been formulated in terms of shared memory and/or message passing communication models. This paper motivates parallel programming models based on broadcast communication and defines and...

—One of the most important issues in peer-to-peer networks is anonymity. The major anonymity for peer-to-peer users concerned with the users' identities and actions which can be revealed by any other members. There are many approaches proposed to provide anonymous peer-to-peer communications. An intruder can get information about the content of the data, the sender's and receiver's identities. ...

Peer-to-peer (P2P) networks have emerged over the past several years as new and effective ways for distributed resources to communicate and cooperate. "Peer-to-peer computing is the sharing of computer resources and services by direct exchange between systems. These resources and services include the exchange of information, processing cycles, cache storage, and disk storage for files." P2P net...

Load balancing is an important problem for structured peer-to-peer systems. We are particularly interested in the consumption of network bandwidth for routing traffic and in the usage of computer resources for object storage. In this paper, we investigate the possibility to simultaneously balance these two types of load. We present a structured peer-to-peer overlay that efficiently performs suc...

This research is a qualitative study which aims to explore the development of EFL learners' speaking proficiency as well critical thinking ability contribute their oral performance in IELTS Speaking Test training course (ISTT) under "Smart classroom" mode. In one participant was interviewed using semi-structured interview methodology with finding that mode, sufficient input and engagement, inte...
