Modern GPGPUs implement on-chip shared cache to better exploit the data reuse of various general purpose applications. Given the massive amount of concurrent threads in a GPGPU, striking the balance between Data Locality and Load Balance has become a critical design concern. To achieve the best performance, the trade-off between these two factors needs to be performed concurrently. This paper proposes...
An FPGA based generic parallel neighborhood search which exploits parallelism at both search and move levels is proposed. A neighborhood partitioning technique is employed to significantly increase parallelism at move level with minimum hardware resource increment. The proposed approach is applied to a tabu search and evaluated using the quadratic assignment problem. Experimental results show that...
The internal flow field in impeller of a torque converter will have great effect on the working characteristics of the torque converter. The numerical model of internal flow field in impeller of the torque converter was established by using the hexahedron grids based on the turbulent model k~e and SIMPLE algorithm. To solve the interaction between the various stages with different speeds, the mixing...
This paper presents the progressive failure simulation of truss structures using the Finite Particle Method (FPM). Three major difficulties in structural collapse simulation, namely the description of dynamic behaviors of structures, geometric and material nonlinearity and fracture, are considered in collapse process. Different from the traditional finite element method generated from continuum mechanics...
Financial distress prediction has drown a lot of research interests in previous literature, and many studies have shown that artificial intelligence techniques achieve better performance than traditional statistical ones. In this paper, we use Least Squares Support Vector Machine (LSSVM) to carry through empirical study for financial distress prediction of China listed companies. The independent variables...
Underway replenishment is an essential component of long-term military naval survival. The idea of the replenishment project evaluation is to integrate different assessment methods. In view of underway replenishment behavior characteristics, this paper proposes the concept of the underway replenishment project , analyzes the replenishment project goals and the principle of project evaluation, and...
Maintenance management often focuses on the minimization of the repair cost and the part replacement cost. In this paper a production cost based maintenance scheme is proposed to minimize the production loss due to unscheduled equipment downtime events. Two maintenance plans, standby redundancy and vendor repair, are discussed and their impacts on the downtime cost are analyzed. The idea is to reduce...
This paper presents a practical design method for the critical-conduction mode power factor correction (CRM PFC) converter by using an interactive mathematical computation and documentation software, the MathCAD. Many design factors affect the performance of a switching converter from the point view of efficiency optimization or dynamic response. The design of a CRM PFC converter is an involved process...
Plate-fin heat exchanger has been widely used in chemical, mechanical and electronic engineering etc. The optimal design of PFHE is an important method to improve the performance of PFHE. According to the engineering requirements, the minimum weight, higher heat efficiency and reasonable pressure loss are set as optimal objectives of PFHE, which is termed as multi-objective optimal problem. To implement...
Since the censored and imprecise information are ubiquitous in the real world, under this fuzzy environment, the supplier selection based on the lifetime for the exponential model is proposed in this paper. The fuzzy estimates ^tp L% of lifetime capability indices tp L of suppliers are obtained according to the approach taken by Buckley [3][4] and the Zadeh's [14] extension principle in fuzzy sets...
This paper presents an energy conservation scheme, maximum unavailability interval (MUI), to improve the energy efficiency for the Power Saving Class of Type II in IEEE 802.16e. By applying the Chinese remainder theorem, the proposed MUI is guaranteed to find the maximum Unavailability Interval, during which the transceiver can be powered down. The proposed MUI only dynamically adjusts one parameter...
