The Internet and associated technology are fast changing the conceptualization and determinants of value to the customer. Marketers would, thus, have to explore what constitutes value for the consumer and determine newer ways to create and deliver such value to the customer. We extend quality-value-loyalty chain and add to this chain trust factor in internet environment. Given certain key behavioral...
The reliability problem and the thermal management problem of active embedded component into organic substrate becomes a bottleneck restricting development. On the one hand, these paper overviews the thermal management features of the technology, the modeling of the thermal management and the application of thermal methods. It does the cooling and the thermal stress simulation analysis for typical...
This paper presents a configuration of 3D-chip stacks with internal channel cooling that include high thermal conductivity layers, channels for heat transport by pneumatic fluid flow, regulation of fluid velocity by channel obstructions bumps, enhanced thermal conductivity across the channel by metal spacers, wiring re-distribution layers (RDL) and electrical continuity across the cooling channels...
In this paper several heat dissipation mechanisms are studied in an effort to improve heat dissipation of a high-power packaged chip in its environment. Specifically we examine a cavity-down structure consisting of a copper plate in thermal contact with the back side of the chip. In order to evaluate the thermal performance of the cavity-down approach, three structures are compared via simulation...
The coefficient of thermal expansion (CTE) of metal (e.g., copper, tungsten and solder) filled in through silicon via (TSV) is a few times higher than that of silicon. Thus, when the metal filled TSV is subjected to temperature loadings, there is a very large local thermal expansion mismatch between the metal and the silicon/dielectric (e.g., Si02), which will create very large stresses at the interfaces...
A novel application of the time reversal technique for multi-source reflector antenna design is proposed in this paper. The focus of a shaped reflector and the time sequence of its feeds can be determined by time reversal method, exploiting its spatial-temporal focusing property. Then a designed three-source parabolic antenna was simulated by the FDTD. The radiation properties show that the designed...
Based on experiment and value conversion methods, the ecosystem service values of straw and Agarics Bosporus waste recycling in a rice-wheat rotation farmland ecosystem was discussed in this paper. The total ecosystem service values of the recycling treatments were both higher than that of conventional cropping, especially the value of fungus waste recycling significantly increased by 46.33%. The...
The centralized monitoring and command system of cable network which is based on the urban power distribution network achieves centralized display the comprehensive information of cables, combining with the cable distribution information, the data of production management, the scheduling data of SCADA (Supervisory Control and Data Acquisition) system, the monitored cable information, the monitored...
According to the System Theory and the requirement in the oil depot area, combined with the application integration of OA, HSE, GIS system, the article describes The Security emergency command system in oil depot. It may realize the HSE management information, the visualization and integration conformity of the storehouse district security hardware, therefore, it is very important to improve the emergency...
This paper describes the impact of lightning on grid line, based on corridor radius algorithm, realize the grid lines surrounding lightning location analysis methods, including lightning occurs time, latitude and longitude, electricity, etc. Through comprehensive analysis of the lightning information and grid lines transmission information, fault information to judge whether lightning cause grid line...
The centralized monitoring and analysis system of transmission lines in mined-out area is based on the indicators of state variables which reflect the health state of the transmission lines in mined-out area. This system uses this pattern which combines transmission tower body with overhead lines, and makes use of the equipment management model and technical measures to manager. It conducts the real-time...
This paper presents a nonlinear adaptive observer to estimate the annular pressure profile throughout the well bore continuously while drilling. A simple mechanistic model is presented that captures the dominant phenomena of the drilling system and forms the basis for model-based observer and control design. A new nonlinear adaptive observer is developed for state estimation and parameter estimation...
Latrine improvement project is an important part of new socialist countryside construction projects. A survey on situation of current rural latrine in Beijing was made, and the problems in the latrine improvement project were analyzed, and then put forward the advices and the solutions of the improvement. Then make a detailed introduction about the types of latrine improvement project to pick up which...
Sewage treatment technology updates day by day, while, it is not easy to apply them to the Beijing rural sewage management, which can be reflected by the idle and inefficient operation of large numbers of sewage treatment facilities. Some appropriate sewage treatment technology for the rural sewage treatment was summarized, and their applications were comprehensively compared to each other, which...
To overcome the shortage of single-thread in communication efficiency, a new model called multithread serial communication which of Windows CE was built. First structured a serial class function, then created the threads and solved the problems that threads could not be synchronized. After being implemented the project of injection manipulator hand-held devices, executive equipments had been accelerated,...
Status of Beijing rural sewage treatment was analyzed comprehensively, that is, analyze Beijing rural water pollution, water pollution reasons, the main characteristics of wastewater and summary of sewage treatment, aiming at providing reference for maintenance, renovation, operation and construction of Beijing rural sewage treatment facilities mentioned.
