Service participants can obtain different service values through participating in multiple service solutions with the same function but different performances and these solutions are usually represented as the pre-designed service models. Whether or to what degree the service values can be implemented under the support of the pre-designed service models is as a critical criterion for evaluating...

One of the promises of the service-oriented architecture (SOA) is that complex services can be composed using individual services. Individual services can be selected and integrated either statically or dynamically based on the service functionalities and performance constraints. For many distributed applications, the runtime performance (e.g. end-to-end delay, cost, reliability and availabilit...

Monitoring distributed applications executed on a computational Grid is challenging since they are executed on several heterogeneous nodes belonging to different administrative domains. An application monitoring service should provide users and administrators with useful and dependable data on the applications executed on the Grid. We present in this paper a grid application monitoring service ...

Simplicity of usage, flexibility of data access, ease of maintenance, time and energy efficiency, and pay as you go policy have increased the usage of cloud computing over traditional computing. Cloud computing should be able to meet the performance expectations of different class of customers. On the contrary, inefficient scheduling algorithms decrease the quality of service experienced by use...

Introduction The Second Urban Primary Health Care Project (UPHCP-II) in Bangladesh started in 2005 with a mandate to extend every component of health services to at least 30% of the poor in catchment areas. Poor were identified through household survey and were provided with free service entitlement cards by the service delivery partners. UPHCP-II started service delivery in partnership with co...

The performances of high-speed network communications frequently rests with the distribution of data-stream. In this paper, a dynamic data-stream balancing architecture based on link information is introduced and discussed firstly. Then an algorithm for simultaneously obtaining the passing nodes and links of a path between any two source-destination nodes rapidly, as well as a dynamic data-stre...

Cloud computing is an emerging concept of information technology that in many countries has an influence on many companies. The research was conducted to evaluate cloud computing adoption in Saudi Arabia; Benefits and hindrances for small and medium-sized enterprises (SMEs). The qualitative research approach is performed by interviews with the management of a variety of SMEs active in the infor...

This report is a survey about service curves used in envelope-based models for worstcase performance evaluation, like Network Calculus or Real-Time Calculus. In a first part, we compare different models and their notions of service curves by establishing a hierarchy and similarities between different types of service curves and in a second part, we compare the behaviours of simple and strict se...

Sociolinguistic research has increasingly turned to examining the use of both the grammar and speech events of black speech by non-Blacks. This phenomenon called language crossing is defined as “the use of language varieties associated with social or ethnic groups that the speaker does not normally ‘belong’ to” (Rampton 1995:14). Although the literature has focused on phonological features, the...
