quality of service (qos) is an important issue in the design and management of web service composition. qos in web services consists of various non-functional factors, such as execution cost, execution time, availability, successful execution rate, and security. in recent years, the number of available web services has proliferated, and then offered the same services increasingly. the same web ...

service oriented enterprises (soes) are subject to constant change and variation. in this paper, the changes are considered from an economic perspective based on service culture notion. once a change is implemented, the costs of some member services may increase, whereas the costs of some other services may reduce. we construct a game theoretic model trying to capture the possible conflicting i...

AIM To investigate the impact of an interdisciplinary low vision service on the vision related quality of life of service users. METHODS 71 patients were interviewed 2 weeks before their appointment with the service and again 6 months later to assess any changes in their vision related quality of life. The majority of these patients had age related macular degeneration. RESULTS After contac...

Strength reduction in structures like an aircraft could be resulted as cyclic loads over a period of time and is an important factor for structural life prediction. Service loads are emphasized at the regions of stress concentration, mostly at the connection of components. The initial flaw prompting the service life was expected by using the Equivalent Initial Flaw Size (EIFS) which has been re...

An original method for service life assessment of building products is proposed. In addition to a rigorous analysis and system modelling, "Evidence Theory" is adapted and used. Allowing the taking into account of uncertainty and ignorance, this tool has proved efficient in our service life assessment procedure. After a short presentation of the context, the concept of "fusion" is sketched; the ...

BACKGROUND Quality of life refers to a person's experienced standard of health, comfort and happiness and is typically measured using subjective self-report scales. Despite increasing scientific interest in the value of dogs to human health and the growing demand for trained service dogs, to date no research has reported how service dogs may affect client perceptions of quality of life. METHO...

the crankshaft is one of the most critically loaded components as it experiences cyclic loads in the form of bending and torsion during its service life. its failure will cause serious damage to the engine so it’s important at the time of design to verify fatigue strength. more challenges in crankshaft design due to increasing vehicle payloads, lower weight requirement, higher efficiency and lo...

The increasing importance of service systems in the global economy prompts researchers to focus on quality to measure the critical interaction between human behavior, IT and society. Building on service-dominant logic and sociomaterialism, this study develops and validates a quality model and measures its overall impact on individual (value, satisfaction), organizational (i.e., continuance inte...
