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...

Implants trigger an inflammatory response, which is important for osseointegration. Here we studied neutrophil extracellular trap (NET) release of human neutrophils in response to sandblasted large-grit acid etched (SLA) implants using fluorescent, confocal laser scanning and scanning electron microscopy. Our studies demonstrate that human neutrophils rapidly adhered to SLA surfaces, which trig...

COSMA proposes a novel SLA management approach for composite services. It supports a composite service provider in managing SLAs with providers of atomic services, in managing SLAs with requesters of composite services, and aligning both SLA management activities with each other. On this basis, a composite service provider can control and optimize its composite SLA management activities during ...

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 ...
