This paper puts forward a way to design and realize a teaching quality evaluation system for part-time teachers. Through the evaluation of part-time teachers in the teaching process, the quantitative evaluation results of the teaching quality of the course can be gained on the basis of analytic hierarchy process to carry on the distribution of evaluation index weights, fuzzy comprehensive evaluation...
In this brief, we propose a new margin scalable discriminative least squares regression (MSDLSR) model for multicategory classification. The main motivation behind the MSDLSR is to explicitly control the margin of DLSR model. We first prove that the DLSR is a relaxation of the traditional $L_{2}$ -support vector machine. Based on this fact, we further provide a theorem on the margin of DLSR. With...
Field signature method (FSM) is used today by many of the world's major oil companies in a wide range of monitoring applications, with advantages of high degree of reliability and accuracy, non-intrusive, reflecting wall thickness visually. In this paper, the theory of FSM used in inner corrosion monitoring was analyzed and the expression of defects evaluation parameter (Fc) was deduced based on the...
Nowadays, a novel BitTorrent technology, Private Tracker, has received extensive attentions in academia. However, most researches work on measuring, analyzing and modeling of Private Trackers towards to Internet or networks. Few work aims at utilizing the PTs model to real life. In this paper, we abstract the idea of PTs model to a universal trade exchange mechanism creatively, and apply it to real-world...
An articulated phase insulator is a new type one, which can avoid the evident hard spots coming from device type neutral sections. Now, articulated phase insulators have been applied in most of high-speed lines in the world. The paper introduces the 7-span articulated phase insulator, mainly to analyse the causes of the over-voltages, calculates the over-voltage of the insulator, makes simulation...
The convergence of Particle Swarm Optimization (PSO) is an important and difficult problem. In this article, a new generalized PSO analysis model (γ-GPSO) is offered with discretization technique to second-order analog system of PSO; Order one or second stability areas of parameters is confirmed Using dynamic random analysis method; Stability region, the contour of the spectral radius, the mean, variance...
This paper proposes a new and practical model to achieve the electricity market equilibrium based on Linear Supply Function Equilibrium (LSFE) model. In the proposed model, the transmission constraint in addition to the generation constraint and the consumers bidding behavior are considered. The coevolutionary computational approach is proposed to solve the market equilibrium problem. Several cases...
A dynamic equivalent approach based on coherency is researched for dynamic simulation test in ±800 kV DC transmission project from Yunnan to Guangdong in China. To reduce the full system, the dynamic equivalent model of large-scale power system based on coherency is established, in which the identification of coherent generator groups, coherent buses reduction, aggregation coherent generator parameters...
We develop a microbenchmark-based performance model for NVIDIA GeForce 200-series GPUs. Our model identifies GPU program bottlenecks and quantitatively analyzes performance, and thus allows programmers and architects to predict the benefits of potential program optimizations and architectural improvements. In particular, we use a microbenchmark-based approach to develop a throughput model for three...
Cloud computing provides a new paradigm for easy access to larger scale computing resources over the Internet, thus offering an alternative solution to huge data processing and heavy computational work in power system. In this paper, InterPSS Cloud Edition, a cloud computing based platform for power system analysis, is set up by InterPSS development team using Google App Engine (GAE). At the current...
Establishing regional power market and optimizing the assets allocation in regional areas are key tasks in China's power industry reformation. South China power market (SCPM) is one of the pilot regional power markets in China and started simulative operation on Nov. 21st, 2005. As the economic development and tariff level in west-east provinces is much uneven, the simulative operation result of SCPM...
