Cloud computing has become a popular paradigm for implementing scalable computing infrastructures provided on-demand on a case-by-case basis. Selfmanageable Cloud infrastructures are required in order to comply with users’ requirements defined by Service Level Agreements (SLAs) and to minimize user interactions with the computing environment. Thus, adequate SLA monitoring strategies and timely ...

To the Editor: Antibodies to a cytosolic soluble liver antigen (SLA), originally detected by an inhibition ELISA using cytosolic liver fractions and proposed as marker of a third type of autoimmune hepatitis (AIH) negative for other autoantibodies, have been also reported in anti-nuclear and/or -smooth muscle antibody type 1 AIH, liver kidney microsomaltype 2 AIH, and autoimmune sclerosing chol...

Due to the large variety in computing resources, Cloud markets often suffer from a low probability of finding matches between consumers’ bids and providers’ asks, resulting in low market liquidity. The approach of service level agreement (SLA) templates (i.e., templates for electronic contracts) is a mean to reduce this variety as it channels the demand and supply. However, until now, the SLA t...

The increased reliance of companies on IT outsourcing has turned management attention to a set of skills of managing relationships with service providers. While practitioners proclaimed that a key to managing outsourcing relationships was with SLA, there existed very little understanding of how effectiveness and impact of SLA on IT outsourcing arrangements was measured. Using a conceptual frame...

Customers of cloud services choose the VMs profiles (SLAs) offered by the provider, and pay according to how long these VMs are utilized. Many works deal with how to decrease the cost of VM requests scheduling, but consider solely the charging models in the SLA. However, other characteristics in the SLA must be taken into account when choosing a VM to execute users’ applications (e.g. processin...

PURPOSE The possibility of immediate or early loading has become popular in implant dentistry. A prerequisite for the immediate or early loading of an implant prosthesis is the achievement of initial stability in the implant. Moreover, in response to clinicians' interest in verifying clinical stability to determine the optimal time point for functional loading, a non-invasive method to assess i...

Spaceborne Interferometric SAR (InSAR) technology used in the Shuttle Radar Topography Mission (SRTM) and spaceborne lidar such as Shuttle Laser Altimeter-02 (SLA-02) are two promising technologies for providing global scale digital elevation models (DEMs). Each type of these systems has limitations that affect the accuracy or extent of coverage. These systems are complementary in developing DE...

In this paper we study hard real time (HRT) communication over a differentiated service network. Differentiated Services was proposed by IETF as a scalable QoS architecture [1]. Diffserv service providers can provide delay and bandwidth guaranteed service (as per service level agreement (SLA)) by implementing diffserv services with a fair packet scheduling algorithm like WFQ. But this QoS is pr...

Implementing and offering other than best effort services in large scale IP networks, such as Internet, has been and still is one of the biggest challenges for network operators, (internet) service providers (I)SPs and vendors on route towards multiservice IP networks and internet. Service Level Agreements (SLAs) play an important role from providers ́ and the customers ́ business point of view w...

Factors that contribute to interspeci®c variation in photosynthetic nitrogen-use eciency (PNUE, the ratio of CO2 assimilation rate to leaf organic nitrogen content) were investigated, comparing ten dicotyledonous species that di€er inherently in speci®c leaf area (SLA, leaf area:leaf dry mass). Plants were grown hydroponically in controlled environment cabinets at two irradiances (200 and 1000...
