Abstract: The widget applications have been very widly used on PC platform and hand-held devices. Widget applications will be widely used on the IPTV platform. This paper describes a widget system of IPTV on the ST-9150 hardware platform which is designed by STM icroelectronics (ST) company. This widget system consists of three parts: widget engine, widget manager and widget applications. The widget engine is come from the Google widget engine which is ported to ST-9150; widget manager is designed using the Qt framework technology; through the Google Desktop IDE, three widget applications are implemented, which is suitable for the IPTV platform. As the conclusion, it provides a IPTV widget system, which can be a good fit for the IPTV platform, and can well organize the widget applications.

Abstract: A model of Electrical Capacitance Tomography (ECT) electrodes array was established by ANSYS Parameter Design Language (APDL). A analysis platform of ECT is developed through the macro feature of APDL for the function of interaction. Based on this fast and approximate calculation of capacitance, optimal design will be put forward more conveniently.

Abstract: Deficiencies are existed for currently formulae of mobility calculation for single loop mechanism. It doesn't reflect the constraint imposed to output components by link group. By analyzing the kinematic parameters of link groups, this paper proposes a new method to calculate the mobility of link group, which is the difference of the sum of the degree of freedoms (DOFs) of all the kinematic pairs and the rank of the kinematic parameters of link groups. Also the DOF can be obtained by the total DOFs of link groups and the rank of kinematic parameters of basis point of the output link. It can be concluded that the new method can not only express the move state of the output link, but the constraint imposed to output components by link group also be reflected. The research results can provide a reference for the structural analysis of the single loop.

Abstract: The importance of customer service in customized design support is introduced. The basic requirements of customized design support are analyzed, including the difficulties and information flow. A model of information flow among customized design, manufacturing and service is built. The layers and support techniques for customized design support are discussed. The customized design support model is set up and the customized design support procedure is presented. A network-based architecture of customized design support system is proposed and the functions are discussed.

Abstract: In this paper, a 3D composite seam image has been firstly preprocessed and then the centerline and key-points have been extracted. After that, a method has been proposed which is based on the optical deviation detection-lateral and vertical deviation detection of the seam. Seam simulation is immediately carried out with MATLAB. It turns out that the deviation error is less than 0.004 mm, and that stitching simulation route are basically the same as the actual seam. It also demonstrates that this method is practical and effective.

Abstract: In this paper, a 3D crane system coordinate system is established for a bridge crane in which the rope length is always changing. The position of the grab in the coordinate system is selected as control objectives, while the cable-car displacements and length of the rope are selected as control variables. Lagrange equations are used for the dynamic analysis. A simulation is conducted in MATLAB environment to analyses the angular motion of the rope caused by its length change and the linear motion of the cable-car.

Abstract: The characteristic of product’s life-cycle customer environment requirements is analyzed. A customer clustering methode for green design is proposed. Conjoint analysis method is used to obtain individual customer’s environment requirements and system-clustering method is used to cluster customers in accordance with their environment requirements preference. Green product customer clustering is realized. Thus, successive development of green product can be supported. Green design oriented customer clustering of soybean milk maker is illustrated to exemplify the method.

Abstract: On the base of appraising synthetically of measuring and testing technique and the monitoring system of thickness, the article analyzed the demand of thickness deviation. It also determined the control core of single chip, and studied on the on-line monitoring system of the wood-based Panel thickness, which is measured by laser sensor and differential transformer sensor and based on the technique of wireless sensors in order to develop monitoring precision and automation standard of blank thickness in wood-based panel industry.

Abstract: In this paper, the spatial structure of heavy metals were quantitatively described to soil in Zhejiang Pinghu City based on statistical methods, and the main factors of the spatial structure of heavy metals were discussed in the study region. The results showed that the soil experimental variogram model fitted better in the study area in the 7 heavy metals of As, Cr, Cd, Cu, Ni, Pb, and Zn. Principal component analysis reflected the elements Pb, Zn, Cu, As, Cr and Ni distribution in a same component; and elemental Hg and Cd each a separate component.

Abstract: Aero2k and SAGE model havebeen developed in the contemporary society when emissions attract extensive attention, especially on aviation emissions. In this paper, origin and functions of SAGE model are introduced simply, while its calculation model is analyzed in detail. Based on SAGE model, process analysis of calculating aviation emissions has been made and Calculation procedure has been designed, then software about calculation of aviation emissions has been developed according to the procedure. There is no much deviation between true values and results based on the software, which is a good proof of feasibility of the software.
