Composite cloud services based on the methodologies of Software as a Service and Service-Oriented Architecture are transforming how people develop and use software. Cloud service providers are confronting the service selection problem when composing composite cloud services. This paper deals with an important type of service selection problem, minimizing the total cost of providing a composite ...

The telecom market is evolving towards services. The arrival of next generation networks with a new generation of service and market deregulation have led to the emergence of many new service providers for whom Service Level Agreement (SLA) management is a key differentiator. Service provider differentiation will depend largely on the reliability of their SLA management and monitoring, and the ...

The possible influence of the pig major histocompatibility complex on reproductive traits is reviewed. Among the parameters investigated, significant associations were observed between SLA and genital tract development in males. Several SLA haplotypes affected either positively or negatively the development of testes, the epididymes and the Cowper's glands, whereas the influence of these haplot...

Scattered look-ahead (SLA) pipelining is a new IIR filter structure that can achieve very high throughput, regardless of multiplier latency. However, the numerical properties of SLA have been largely unexplored. In this paper we analyze the finite word-length (FWL) performance of SLA filters under fixed-point arithmetic. To support this analysis, two new state variable descriptions (SVD) are in...

A systematic nomenclature for the genes and alleles of the swine major histocompatibility complex (MHC) is essential to the development and communication of research in swine immunology. The Swine Leukocyte Antigen (SLA) Nomenclature Committee of the International Society for Animal Genetics (ISAG) has reviewed all of the DNA-sequence information for MHC class II genes, available in GenBank/EMB...

Prognostic evaluation is important for the management of patients with autoimmune hepatitis (AIH). Although some autoantibodies have been associated with disease activity and outcomes, the implication of antibodies to soluble liver antigen (anti-SLA) remains controversial. To conduct a meta-analysis of observational studies which addressed differences in clinical characteristics by anti-SLA sta...

In recent years, extensive research has been conducted in the area of Service Level Agreement (SLA) for utility computing systems. An SLA is a formal contract used to guarantee that consumers‟ service quality expectation can be achieved. In utility computing systems, the level of customer satisfaction is crucial, making SLAs significantly important in these environments. Fundamental aspect is t...

Swine leukocyte antigen (SLA) class I molecules play a crucial role in generating specific cellular immune responses against viruses and other intracellular pathogens. They mainly bind and present antigens of intracellular origin to circulating MHC I-restricted cytotoxic T lymphocytes (CTLs). Binding of an appropriate epitope to an SLA class I molecule is the single most selective event in anti...

Automating SLA monitoring involves minimizing human involvement in the over-all monitoring process. SLA monitoring is difficult to automate as it would need precise and unambiguous specification and a customizable engine that collects the right measurement, models the data and evaluates the SLA at certain times or when certain events happen. Also most of the SLA neglect client side measurement ...

The need for Service Level Agreements (SLAs) to supervise the consumption of services is increasing in business applications and Cloud scenarios due to the penalties that can apply for violation of SLA terms. Such a need for SLAs boosts the importance and complexity of SLA lifecycle supporting systems (SLA-driven solutions). In our work we propose to improve the current support to develop SLA-d...
