The recent years have seen a considerable increase in the number of cluster systems. These systems provide a very good performance-cost ratio. However, in order to meet the requirements for ever-increasing computing power of present day applications, several SMP cluster systems have emerged. By deploying two or more processors per workstation can increase the performance of a cluster significan...

The chapter provides an overview of virtual music communities focusing on novel collaboration environments aiming to support networked and geographically dispersed music performance. A key objective of the work reported is to investigate online collaborative practices during virtual music performances in community settings. To this effect, the first part of the chapter is devoted to reviewing d...

The present paper addresses the dynamics of innovation, by extending the analysis beyond a static-economic perspective. It offers a dynamic-institutional mapping of relational capacities to dynamically innovate. Its main goal is to contribute to the abovementioned research theme by presenting a new methodology able to pinpoint different trends in the relational capacities of institutions when t...

This is a survey paper. In this paper various methods used for power estimation in wireless communications have been discussed. Wireless communications has become an inseparable part of our life. Power consumption is one of the major factors that decide the communication system quality. Accurate power estimation has an important role for power control and handoff decisions in mobile communicati...

Recently, underwater wireless sensor network is one of the popular research topics to scientist. There are many novel methodologies to reach the goal of the effectiveness network performance such as cluster-based structure, in-network data aggregation, etc. In this paper, we assume the network is clustered by a specific clustering scheme. Then, we suggest a new geographicaldata-aggregation meth...

Big Data aims at the efficient processing of massive amounts of data. Performance modeling is often used to optimize performance of systems under development. Based on experiences from modeling Big Data solutions, we describe some problems in applying performance modeling and discuss potential solution approaches.

The success of a learning environment can be measured in terms of improvement in learner performances as well as positive learner engagement in metacognitive traits. A large body of educational technology literature establishes a positive correlation between the application of learning technologies and learner performances. In addressing the other aspect of success, this chapter presents a stud...

A pilot study is presented comparing the performance of complex bowing patterns of three violinists. Analysis of the movements revealed a subtle coordination between string crossings and bow changes in repetitive bowing patterns across two and three strings. Clear differences between the performances of the three players were found that could be interpreted in terms of consistency and efficienc...

The education of the Turkish makam music practice is carried out by face-to-face sessions with the masters. Our aim in this work is to present a rhythm training software that helps users imitate recording of a master and receive visual feedback about their performances compared to the recording of the master. The system automatically detects onsets in the recordings and then performs comparison...

This paper aims to assess the French Front national’s performances in municipal office following its success in securing a majority in four city councils in the mid-1990s. First, a brief account of the local political opportunity structures that participated in the municipal success of the FN is provided. The paper then suggests a characterisation of two divergent models of policy and vote-seek...
