We consider some dependability management systems(IEC300, NASA AHB5300.1 and DIN VDE 0801) with reference on IEC300. Part I of IEC300(IEC300-1) covers the essential features of a comprehensive dependability programme for the planning, organization, direction, and control of resources to produce products which will be reliable and maintainable. We consider the contents of IEC300-1； scope, normative references, definitions, management responsibilities, product or project independent programme elements and project specific programme elements.

One of the most important challenges facing companies in the age of internet business is the proper alignment customers needs with internet business system that allaws them to react rapidly and continuously. This paper proposes a methodo1ogy to align analyzing customer's requirements with implementing Internet business system The methodology consists of five Phases. It covers from customer analysis to Internet business system implementation, and each of the five phases has its own activities and outputs. A real- world case is proposed to illustrate the application of the methodology.

In this paper, we survey the parallel machines scheduling problem with GoS eligibility constraints so as to minimize the makespan. Our survey covers off-line, online and semi-online scheduling problems. In the case of online scheduling, we only focus on online scheduling one by one. Hence we give an introduction to the problem and present important results of the problem.

Motion segmentation is a fundamental technique for analysing image sequences of real scenes. A process of identifying moving objects from data is a typical task in many computer vision applications. In this paper, we propose motion segmentation that generally consists from background subtraction and foreground pixel segmentation. The Approximated Median Filter (AMF) was chosen to perform background modeling. Motion segmentation in this paper covers RGB video data.

Space truss structures may be fabricated in any of several common grid configurations. With different configurations, the truss performance varies considerably affecting both its competitiveness and suitability for specific applications. The work presented in this paper is an assessment of the most commonly adopted truss configurations and their effect on truss characteristics such as the stiffness/weight value, member stress distribution, number of joints and members, degree of redundancy and cost. The study is parametric and covers wide variations of truss aspect ratios, boundary conditions and span/depth ratios. The results of this study could be of significant value to the design of space truss structures.

Observing that a realcompactification Y of a space X is Wallman if and only if for any non-empty zero-set Z in Y, $Z{\cap}Y{\neq}{\emptyset}$, we will show that for any pseudo-Lindel$\ddot{o}$f space X, the minimal quasi-F $QF({\upsilon}X)$ of ${\upsilon}X$ is Wallman and that if X is weakly Lindel$\ddot{o}$, then $QF({\upsilon}X)={\upsilon}QF(X)$.
