Service-Oriented Computing (SOC) is a new computing paradigm that utilizes services as the basic constructs to support the development of rapid, low-cost and easy composition of distributed applications even in heterogeneous environments. The visionary promise of Service-Oriented Computing is a world of cooperating services where application components are(More)
Service oriented computing (SOC) is an emerging cross-disciplinary paradigm for distributed computing that is changing the way software applications are designed, architected, delivered, and consumed. Services are autonomous, platform-independent computational elements that can be described, published , discovered, orchestrated, and programmed using(More)
This study was designed to investigate the influence of posture on salivary cortisol concentrations in healthy volunteers. In a balanced cross-over design 24 subjects were exposed at 1 week intervals to different body positions (sitting [S], lying [L] upright [U]) for 20 min in each condition. Before, during and after the experimental treatment measures of(More)
Peer-oriented computing is an attempt to weave interconnected machines into the fabric of the Internet. Service-oriented computing (exemplified by web-services), on the other hand, is an attempt to provide a loosely coupled paradigm for distributed processing. In this paper we present an event-notification based architecture and formal framework towards(More)
Xenomelia is the oppressive feeling that one or more limbs of one's body do not belong to one's self. We present the results of a thorough examination of the characteristics of the disorder in 15 males with a strong desire for amputation of one or both legs. The feeling of estrangement had been present since early childhood and was limited to a precisely(More)
7 Abstract The international standard IEC 61131-3, which supports Brad Cox' concept of " Software-ICs " 9 for industrial control programming, is increasingly being used in safety-related application domains. They include safety-instrumented functions, such as burner management, emergency shut-11 down and gas leak detection, but also complex automation(More)
The software architect is concerned with both functional and non-functional design. An important task in functional design is the adaptation of a component's provided interface for use by other components. In non-functional analysis the focus is rather on the prediction and reasoning about reliability and performance properties. We present a method for(More)
Computing with services has attracted much attention as a promising approach for developing distributed applications. The approach is often advertised as being superior to distributed component-based software engineering (CBSE), because it provides a higher potential to bridge heterogeneous IT application and infrastructure landscapes. It facilitates(More)
