Present work introduces the sustainable useful storage capacity as the minimum storage capacity able to satisfy the water demand for drinkable, industrial and irrigational purposes and necessary in order to overcome water deficit situations which, at least in Central Southern Italy, occur in the summer, when agricultural demand is really high. Sediment volumes to be removed from the reservoir bottom will be calculated as the difference between the current and the sustainable useful storage capacities of the reservoir in study. The calculation methodology of the useful sustainable storage capacity, based on the reservoir water balance between inflows at the reservoir and water demand, has been applied to the Camastra reservoir (Basilicata, Southern Italy), for which numerous reliable data including more than 40 years of inflows and water supplied volumes and data relative to 7 bathymetric surveys are available. Result analysis shows that this methodology, at least in the study case, enables sediment quantities to be removed more sustainably from a technical, economical and environmental point of view.

With the adjustment of urban industrial structure,a large number of ruins have emerged in cities,and the waste materials left by these ruins not only occupy urban space resources,but also seriously damage the ecological environment.How to identify the value of waste materials through landscape thinking and how to rationally reuse these waste materials through landscape methods is the focus of this paper.

The shortage of water resources is severe in Beijing. The shortage of eco-environmental water and the sewage discharge over the environmental capacity are main bottlenecks that restrict the improvement of water environment. The reuse of wastewater could not only reduce the discharge of pollutants,but it could also increase the consumption of eco-environmental water. Therefore the reuse of wastewater is an important approach to improve the water environmental quality. Combined with the formulation process of Regulations of Beijing on Prevention and Control of Water Pollution,the current situations of prevention and control of water pollution in Beijing,the discharge of pollutant,water environmental quality,the population and economic development and water resources and so on were analyzed. And the bottlenecks that restricted the improvement of water environmental quality were found. And the necessity of solving the control of water pollution by reusing the wastewater and ensuring the consumption of eco-environmental water was analyzed from the perspective of the control of water pollution. And some legislative countermeasures were put forward,which provided new ideas for solving the problem of the prevention and control of water pollution and improving the water environmental quality. It was of important reference values for local governments（ especially water-deficient regions） to make relative polices or plans of water pollution control and water environmental protection.

La méthode de la Balance Harmonique est une méthode très effective pour le traitement des problèmes non-linéaires dans la théorie classique du contr(?)le. Une idée fondamentale de la méthode consiste du jugement de l’existence d’une solution périodique d’une équation originale à la base de l’existence d’une solution lériodique d’une équation approximative. Cette méthode de l’ingénieur était auparavant dépourvue d’une démonstration rigoureuse. A. I. Mees et des autres auteurs ont fourni

A continuing challenge for software designers is to develop efficient and cost-effective software implementations. Many see software reuse as a potential solution;however, the cost of reuse tends to outweigh the potential benefits. The costs of software reuse include establishing and maintaining a library of reusable components, searching for applicable components to be reused in a design, as well as adapting components toward a proper implementation. In this context, a new method is suggested here for component classification and retrieval which consists of K-nearest Neighbor (KNN) algorithm and Vector space Model Approach. We found that this new approach gives a higher accuracy and precision in component selection and retrieval process compared to the existing formal approaches.

The number of software supported systems in vehicles is constantly growing.All carmakers have more or less problems to handle the high number of software functions.Because,traditionally,each function is implemented by a separate control unit,also the number of control units has reached a tremendous level.The key points to master this situation are reusing und integration of functions.The AUTOSAR standard supports both approaches by defining standardized interfaces for software components.This chapter describes the approach to develop software components along the well-known V-Model.All process phases,from the analysis phase to the test phase of the function oriented development process are shown.Furthermore,all tools supporting the different phases are demonstrated.

WiMAX Network Frequency Planning

作者： Nguyen Trong Hieu（阮仲孝）昆明理工大学

学位级别：硕士

The IEEE 802.16 standard, commonly known as WiMAX, is the latest technology that has promised to offer broadband wireless access over long distance. Since 2001 WiMAX has evolved from 802.16 to 802.16d for fixed wireless access, and to the new IEEE 802.16e standard with mobility support. In this paper, we provide an overview of the state-of-the-art mobile WiMAX technology and its development. Next, we focus our discussion on deployment scenarios and performance analysis of mobile WiMAX in Vietnam, a developing country with fast growth in Telecommunications.In practice, mobile WiMAX network planning (IEEE Std 802.16e) is described by using GENEX U-net. The system level simulations scenarios (channel models, frequency reuse planning, system loading, etc) will be introduced. Evaluated performance of mobile WiMAX system through fully planning by various parameters of multi-cellular deployment will be presented and discussed.
