abstract background: there are several evaluation models that can be used to evaluate the effect of in‑service training; one of them is the kirkpatrick model. the aim of the present study is to assess the in-service training of cardiopulmonary resuscitation (cpr) for nurses based on the kirkpatrick’s model. materials and methods: this study is a cross‑sectional study based on the kirkpatrick’s ...

Extended service-oriented architecture –based web services for open environments sets numerous requirements. Issues such as composition and management of services become important, yet neither web services nor the current commercial platforms contain the required capabilities, let alone are mature enough for production use. This paper focuses in particular to service-level management, providing...

The ongoing trend towards a global services economy creates considerable market opportunities and challenges for providers of Software-as-aService (SaaS). For meeting customer expectations, an on-demand business model and a service-oriented infrastructure capable of composing services into service networks are the primary approach. Ensuring quality of service and providing detailed guarantees v...

Quantitative analysis of quality-of-service metrics is an important tool in early evaluation of service provision. This analysis depends on being able to estimate the average duration of critical activities used by the service but at the earliest stages of service planning it may be impossible to obtain accurate estimates of the expected duration of these activities. We analyse the time-depende...

Evaluating the reliability of loosely coupled Software as a Service through the paradigm of a cluster-based and non-cluster-based web server is considered to be an important attribute for the service delivery and execution. We proposed a novel method for measuring the reliability of Software as a Service execution through load testing. The fault count of the model against the stresses of users ...

My thesis is that practical language support can be provided for Service-Level Agreements (SLAs) for Application-Service Provision (ASP), which is better than that provided by pre-existing languages in that: it provides greater assistance in expressing conditions that mitigate the risks inherent in ASP; and disputes related to agreements expressed in this manner may be more easily resolved in s...

We add specifications of location-aware measurements to performance models in a compositional fashion, promoting precision in performance measurement design. Using immediate actions to send control signals between measurement components we are able to obtain more accurate measurements from our stochastic models without disturbing their structure. A software tool processes both the model and the...
