This research sets out to help computational modellers, to select the most cost effective Cloud service provider. This is when they opt to use Cloud computing in preference to using the in-house High Performance Computing (HPC) facilities. A novel Quality-aware computational Cloud Selection (QAComPS) service is proposed and evaluated. This selects the best (cheapest) Cloud provider‟s service. A...

Flow-Aware Networking (FAN) architecture is evaluated in this dissertation with regard to its service differentiation and quality of service (QoS) assurance capabilities. The network neutrality debate is presented first, and it is shown that the potential resolutions will have a strong impact on QoS architectures. It is also shown that FAN, as well as all the proposed mechanisms, is perfectly s...

background: the quality of care from the perspective of people with type 2 diabetes using a new model (cqmh) including three dimensions of quality in health care (technical, service and customer quality) was assessed. methods: a cross-sectional survey with a sample of 577 people with type 2 diabetes was conducted. measures were self-reported adherence to national guidelines for technical qualit...

behaviour orthogonality We claim that our contract and policy concepts support the reasoning about extra-functional behaviour to be orthogonal to functional types. In our architecture we introduce policies and their corresponding software components (activators) as an extra level of indirection; i.e. we do not apply policy implementation components directly but rather via a policy component. Th...

the purpose of this research is measuring and comparing service quality and ranking its dimensions in melli bank branches of esfahan city. for attaining this purpose systr-sq scale is used. this scale is special for measuring bank service quality. questionnaire drive from this scale is contained four dimensions and 21 question. dimensions are service system quality, behavioral system quality, s...

Purpose – Context correctness and fault handling are very important to the quality of service in context-aware applications. However, they are often ignored by researchers and application developers. This paper aims to present a model for context-aware applications. Design/methodology/approach – This paper proposes a transaction model for context-aware applications, in order to provide a unifor...
