In recent years, the trend in large-scale equipment of grinding classification process becomes increasingly common in metallurgical plant. This trend raised the new requirement of much higher efficiency and performance precision in large-scale griding process. Taking into account the peculiarity of strong disturbances and wide operation range in most of domestic concentration plant, several practical...
Data path connection elements usually consume a significant amount of both power and area on a VLSI chip. In this paper, we focus on the port assignment problem for multiplexer (MUX) and interconnection optimization in High-Level Synthesis. Given a binding solution of operations and variables, the port assignment problem connects the registers to the operator ports through MUXes, to minimize the interconnections...
In this paper, we address the problem of scheduling operations into control steps with dual threshold voltage (dual-Vth) technique under timing and resource constraints. Recently, some scheduling methods are proposed based on the mobility overlap removal, and it is a hard problem to remove the mobility overlap optimally. There might be no feasible solution with an improper mobility overlap removal...
In order to cultivate talents and raise the design ability for power converters at engineering education on campus, the design methodology of a flyback dc/dc converter is introduced step by step in this paper. First of all, the fundamental of switching power converters is analyzed and described in this paper. Later, the power converter is modeled and simulated. The open and closed loop controls of...
In order to resolve the problem that ant colony algorithm solves large-scale WTA (weapon-target assignment) problem will consume a large amount of time, a parallel ant colony algorithm is proposed. Making full use of OpenMP parallel optimization technology, coarse-grained parallel strategy, and the advantage of multi-core in PC, take the cyclic iteration and cyclic assignment, which is the main time-consuming...
The feasibility of using constructed mangrove wetlands to treat saline municipal wastewater was evaluated in this study. Constructed wetland, acting as an ecological engineering alternative, is capable of reducing NH4+-N, TN, TP and COD from saline wastewater. During the 10 months' operating period, the constructed wetland was operated with salinity increasing from 10 to 50 parts per thousands (ppt)...
Zhejiang private enterprises which are in the process of transforming and upgrading of staff need to pay more attention to the increasing work pressure on their staff and ensure that they would be committed to their work. In this paper, the mechanism of role stress impacting on job involvement is analyzed. The theoretical framework is developed to deduce the relationship among role stress, job involvement...
China's ancient capitals formed unique urban space form system in the long historical development, the most representative among which, was metropolis space constrained strongly by orthodox etiquette thoughts. As the capital of thirteen dynasties, Luoyang is the most representative in metropolis space, as its evolution process reflects all the features from early to mid stage of China's ancient capital...
A disturbance observer enhanced model predictive control approach is addressed in this paper for the typical industrial process control systems. The proposed method is applied to a practical level tank system subject to severe disturbances. Both simulation and experimental results show that the proposed method significantly improves the disturbance attenuation property of the model predictive control...
The human capital level is an important factor that affects national innovation capacity. The formation and accumulation of human capital are mainly from higher education. Selecting the number of patents to represent national innovation capacity, and the number of college students to represent human capital, using Johansen co-integration test and Granger causality test, we have a correlation analysis...
With the development of high rate data transmission technology via distribution line communication, the electric power, data, voice and video can be transferred in the same electric power distribution network, and the technology will be put in operation widely in the future. However the traditional technology of power line communication is not adaptable to the complex and harsh environment of distribution...
