Compared with hardware, software reliability is more dependent on design quality. For this reason, the quality of software design is very important to software reliability. Nowadays, carrying out software reliability design criteria is one of the primary means to improve software reliability, and it could also help to summarize experience and lessons learned. After the essence and method of software reliability design being cleared, some implied design ideas for reliability design criteria are elaborated. As the same time the criteria examples are given. Finally, the method on how to apply software reliability design criteria is advanced. The goal of this research is to provide a reference to software reliability design.

In this paper, we present a novel Customized Management (CM) model based on given goals. First, the knowledge base is established to store the standardized scenario data involved with business goals with the help of business experts. Then based on such knowledge base, a customized management model could be created by means of Case-Based Reasoning (CBR) technique so as to satisfy the specific management requirements. We present the definition of CM, describe its creating process, and discuss the experiment result.

To study dynamic performances of wind turbine generator system (WTGS), and to determine the control structures in laboratory. The dynamic torque generated by wind turbine (WT) must be simulated. In there paper, a dynamic wind turbine emulator (WTE) is designed, which consider wind shear and tower shadow effect, and a dynamic torque compensation scheme is also developed to compensate the different inertia between a lab scale motor and a actual rotor blade and shaft. The dynamic torque is taken as reference to control an inductance motor which is driven by an inverter to simulate the wind turbine. The simulation results show this simulation system is feasible and efficient. The wind turbine simulator close to actual ones and can be used as a substitute for actual wind turbine in experiment.

A matchmaking algorithm is presented which uses semantic vector space model to determine the match between agricultural materials seekers and advertisers. A matchmaking model is proposed based on OWL. Finally an architecture based on ASP.NET and the system functional modules is designed and implemented. For farmers, the Agricultural Materials Exchange Platform (AMEP) is simple and easy-to-use.

The control of acceleration and deceleration of stepper motor is one of the most key technologies of CNC system development. Acceleration is discontinuous in linear acceleration and deceleration, which caused impact in NC machining. The exponential algorithm has a strong tracking capability but weak stability at higher speed. The questions could be overcome by conventional S-curve acceleration and deceleration implementation method, but the algorithm is too complex. So a new method was proposed to implement S-curve acceleration and deceleration. This paper presents five-stage model of S curve acceleration and deceleration algorithm to satisfy the actual roller polishing machine needs. The algorithm consists of five kinematic stages: increasing acceleration stage, decreasing acceleration stage, constant-speed stage, increasing deceleration stage and decreasing deceleration stage. At the starting point and the ending point, the velocity is zero and the jerk is absolutely the maximum value J. Analysis shows that: the acceleration curve of the algorithm is a continuous curve, and there is a first-order continuous relationship between time and speed, a smooth velocity and acceleration can be obtained, which is to avoid the impact when the CNC system accelerates and decelerates or reverses. The application on roller polishing machine shows that : compared with the traditional S-curve, the algorithm can make sure the acceleration is continuous, the speed changes smoothly, the flexibility is improved and the algorithm is easy to implement.

To accurately characterize and effectively control the two-echelon inventory system of a telecom operator, this paper establishes a model consisting of a distribution center with multiple warehouses, with an objective function for the optimization of average total inventory and delivery costs. And the model determines two-echelon distribution system's regular stock replenishment policy, safety stock policy and transshipment policy to improve the operational efficiency of the overall supply chain. A numerical example is provided at the end of the paper to illustrate the applicability of the proposed model and methodology.

Based on the Production Function Model, the paper analyzes the interrelation of transportation infrastructure investment and economic growth in different provinces from 1994 to 2009. And in the conditions of constant returns to scale and increasing returns to scale, the paper also calculates the output coefficients of provincial transportation infrastructure investment respectively. The result is that the promotion effect of transportation infrastructure investment to economic growth is greater in developed region, and transportation infrastructure, on which investing should focus on the long term development of economy, is the necessary condition to the promotion of economic growth rather than the sufficient condition.

It is of great importance to put forward an optimal decision scheme as to the emergency control of water bloom in lake and reservoir, so as to prevent water bloom in time and protect the water environment effectively. Based on in-depth analysis on the emergency control decision model and control method of the water bloom, a fuzzy Bayes decision model on the basis of the comprehensive restrictions of minimal risks and costs has been put forward specifically. The fuzzy membership function was adopted to perform fuzzy regional control to the prior probability, and introduced the influence of comprehensive conditions of minimal risks and costs to the result of decisions by weight adjustment, and this method has been successfully applied in the water bloom emergency control of lake and reservoir as the preferable decision scheme in Beijing. At the same time, we have developed an auxiliary decision system of water bloom emergency control information in lake and reservoir, providing valid evidence for environmental protection departments to perform water bloom prevention in lake and reservoir.
