The object of our investigation is a software architecture for adaptive Service Level Agreement (SLA) management in value chains for service individualization. We address the problem that current SLA management is not capable to represent the full complexity of SLAs existing in real-world service industries. The problem is investigated from a functional-analytical supply chain perspective. The ...

PREMISE OF THE STUDY Darwin first proposed that species with larger ecological breadth have greater phenotypic variation. We tested this hypothesis by comparing intraspecific variation in specific leaf area (SLA) to species' local elevational range and by assessing how external (abiotic) filters may influence observed differences in ecological breadth among species. Understanding the patterns o...

There are few computational models of second language acquisition (SLA). At the same time, many questions in the field of SLA remain unanswered. In particular, SLA patterns are difficult to study due to the large amount of variation between human learners. We present a computational model of second language construction learning that allows manipulating specific parameters such as age of onset ...

Commonly-used memory units enable a processor to load and store multiple registers in one instruction. We showed in 2003 how to extend gcc with a stack-location-allocation (SLA) phase that reduces memory traffic by rearranging the stack and replacing some load/store instructions with load/store-multiple instructions. While speeding up the target code, our technique leaves room for improvement b...

Monitoring of Service Level Agreements (SLAs) is required to determine if the Quality of Service (QoS) provided by a service provider satisfies the expectations of a service consumer. Although tools exist that can generate the software required to evaluate SLAs from the SLA specifications themselves, the code required to gather metric data is still predominantly coded by hand: a time consuming ...

In pig, very little information is available on the non classical class I (Ib) genes of the Major Histocompatibility Complex (MHC) i.e. SLA-6, -7 and -8. Our aim was to focus on the transcription pattern of the SLA-7 gene. RT-PCR experiments were carried out with SLA-7 specific primers targeting either the full coding sequence (CDS) from exon 1 to the 3 prime untranslated region (3UTR) or a par...

As the Internet is undergoing substantial changes, there are many demands for the quality of the communication. Differentiated Services was standardized to meet such requirements. Currently, it is assumed that Diffserv is used under static Service Level Agreement (SLA). Under static SLA, the agreement between the service provider and the service subscribers are made as a result of negotiation b...

Modelling and Simulation is increasingly becoming popular in the design process of dynamic network systems. In network management, simulation analysis helps to validate the network models as well as enhance network service operations. In this paper we present simulation as an important process in understanding and analysing SLA management and monitoring. In general, simulation studies are not c...

An increasing number of organisations decide to promote their core competence only. So, they outsource the required IT Services to an IT service provider and negotiate a Service Level Agreement (SLA) which is the contract between the provider and the organisation (customer). One of the major problems of SLA negotiation is the knowledge gap between provider and customer. The knowledge gap is the...
