One fundamental problem in services computing is how to bridge the gap between business requirements and various heterogeneous IT services. This involves eliciting business requirements and building a solution accordingly by reusing availab.e services. While the business requirements are commonly elicited through use cases and scenarios, it is not straightforward to transform the use case model into a service model, and the existing manual approach is cumbersome and error-prone. In this paper, the environment ontology, which is used to model the problem space, is utilized to facilitate the model transformation process. The environment ontology provides a common understanding between business analysts and software engineers. The required software functionalities as well as the availab.e services’ capabilities are described using this ontology. By semi-automatically matching the required capability of each use case to the availab.e capabilities provides by services, a use case is realized by that set of services. At the end of this paper, a fictitious case study was used to illustrate how this approach works.

This paper proposed an embedded smart sensor which is consisted of a 6 DOF (Degree Of Free) IMU (Inertial Measurement Unit), a 3-axis magnetic compass, a monocular camera and a DSP processor which is high performance and power saved, and briefly discussed the design and construction of the system's hardware. By using this embedded smart sensor, we proposed a attitude determination method which is based on the quaternion and the epipolar geometry. The experimental results demonstrated the effectiveness of the methods.

This paper studied the calibration method for a type of embedded smart sensors which are integrated with inertial, magnetic and vision sensors. A set of calibration and modeling methods which are suitable for the low cost applications have been proposed. For the deterministic items and nondeterministic items, we used the method of modulus matching of the input vectors and the method of time series analysis to calibrate and modeling them respectively;for the relative rotation between the accelerometers' frame and the camera frame, we proposed a calibrating method which is based on the gravity vector and plumb line. The experimental and simulation results demonstrated the practicability and effectiveness of these methods.
