Quality-of-service (QoS) in Web services encompasses various non-functional issues such as performance, dependability and security, etc. As more and more Web services become available, QoS capability is becoming a decisive factor to distinguishing services. the management of QoS metrics directly impacts the success of services participating in workflow-based applications. therefore, when services are created or managed using workflows or Web processes, the underlying workflow engine must be able to estimate, monitor, and controlthe QoS rendered to customers. In this paper, we present an approach to give QoS of service composition based on a decomposing algorism and the numerical analysis of stochastic well-formed workflow (SWWF) models of web service composition.
In this paper we present the design and implementation of a telematic network to provide real-time location based services for tactical units which interconnects soldiers, weapons systems, fire control units, sensors,...

A newly proposed drive mechanism for robot's joints based on a principle of twisted strings was developed and is used to power the joints of a five fingered robotic hand. the proposed mechanism is named Twist Drive because it generates a pulling force by twisting two flexible strings on each other. Properties of the mechanism are presented in the paper and application to a five fingered robotic hand is demonstrated. Low-cost, lightweight, and muscle-like operation are the main characteristics of the proposed drive and is therefore beneficial in production of a light-weight, human size robotic hand that can be used in robotics as well as in prosthetics. A prototype of five fingered robotic hand is presented, and its mechanical and control systems are explained.

the OSEK/VDX standard provided by European automobile industry and adopted by ISO organization is the international criterion of automotive embedded software development platform. the vehicle software based on the OSEK/VDX standard has good replantation and expandability to satisfy the exploitation requirements of control system, automobile meter, automobile communication and navigation, automobile security and entertainment equipment, automobile servicing and diagnoses. In this paper, first, we replant the u C/OS-II kernel to the chip named MC9S12DP256B;then, according to the OSEK/VDX standard, we modify the kernel and test it. Testing code shows the operating system running well.
