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...

The aim of this paper is to introduce and present the main drivers and basic concepts for SLA management. We discuss the business requirements according to two points of view: the Customer and the Service Provider, and we go into more detail on the technical requirements for both the SLA contract itself and the SLA Management system. Finally, we give an overview of SLA management open issues in...

background: leishmaniasis is a worldwide disease prevalent in tropical and sub tropical coun­tries. many attempts have been made and different strategies have been approached to develop a potent vaccine against leishmania . dna immunisation is a method, which is shown to be effec­tive in leishmania vaccination. leishmania soluble antigen (sla) has also recently been used leishmania vaccination....

A Service Level Agreement (SLA) is an electronic contract between the consumer and the provider of a service. It governs their business relationship by clarifying expectations and obligations of participating entities, with regard to the service and its quality. SLAs are already the prime paradigm for the description of cloud computing services. Once an SLA is established, the provider has to e...

The highly polymorphic swine major histocompatibility complex (MHC), termed swine leukocyte antigen (SLA), is associated with different levels of immunologic responses to infectious diseases, vaccines, and transplantation. Pig breeds with known SLA haplotypes are important genetic resources for biomedical research. Canadian Yorkshire and Landrace pigs represent the current specific pathogen-fre...

Service Level Agreements (SLAs) are currently one of the major research topics in Grid Computing. SLA negotiation protocols define a business relationship between consumer and provider and are thus a necessary part of any commercial Grid application. In the Grid environment, an SLA negotiation protocol for a workflow becomes complicated because of its structure which includes many dependent sub...

For decades now, questions about the role of corrective feedback in second language acquisition (SLA) have been hotly debated, spawning a great deal of theoretical and empirical research. Although the facilitative role of corrective feedback in SLA has received some empirical support, the claims regarding its impact on SLA have yet to be fully or decisively substantiated. In order to move this ...

This paper illustrates the advantages of laboratory research into SLA by describing two studies of acquisition of second language syntax. The first addresses the question of whether human morphological abilities can be understood in terms of associative processes or whether it is necessary to postulate rule-based symbol processing systems underlying these skills. We demonstrate that acquisition...
