Placement and routing run-times continue to dominate the automated FPGA design flow. As the size of FPGA architectures continue to grow exponentially, it remains critical to develop parallel tools for FPGA design where the amount of exposed concurrent work scales with the size of the designs to be synthesized. In this paper, we propose a novel algorithm for parallel placement, based on simulated annealing,...
Re-supplying loads on outage through cross-connect from adjacent feeders in a distribution system may cause voltage drop and hence require load shedding. However, the surplus PV generated in some of the LV feeders can prevent load shedding, and improve reliability. In order to measure these effects, this paper proposes the application of Direct Load Flow method[1] in reliability evaluation of distribution...
The aim of this paper was to separate the EEG recordings into cerebral and noncerebral waves and compare a statistical properties of chosen components using the coefficient of excess kurtosis. Noncerebral waves, particularly the ocular artifacts, should be properly identified, because some of them imitate the cerebral potentials. The eye opening and closure, blinks or eye flutter are similar to the...
This paper proposes model predictive control (MPC)-based cruise control method. A two-wheeled vehicle is a nonlinear system with nonholonomic constraints. Therefore, a large number of computations is required for optimization-based control. Most conventional studies have assumed that the leader vehicle runs along a predefined trajectory.
Knowledge on extent of changes in magnitude and oscillations of voltage on the power network buses due to load changes on the weak buses, facilitate appropriate identification of wind source interface points in a power network and design of controllers provided with the wind power generation and delivery facilities. This paper addresses the influence of the basic network parameter based descriptors...
RFID (Radio Frequency IDentification) has been used in many applications now; therefore the volume of RFID data is enormous. How to clean and store data is becoming the research focus. For data cleaning, many methods have been proposed, and we first simply introduce these methods and models with some comments. We propose a structure of RFID database which has two levels: raw level and cleaned level,...
There is more to choosing a book than simply keyword searching. Browsing is a fundamental part of the information seeking process, and one that information seekers profess to value, though it has attracted little study. This dearth of research is undoubtedly in part because browsing is nebulous and difficult to quantify. In this paper we use a large circulation dataset from an academic library consortium...
Improving the grid efficiency level is a major way to achieve economic operation and sustainable development of the power grids. Previous studies on power industry energy conservation are much concentrated on supply side or large power grid, while energy conservation study on distribution side is still in its infancy. Studies have shown that the loss of distribution grid accounts for 3/4 of the total...
A new fuzzy clustering algorithm (PPC) based on project pursuit model is presented in the paper. The main defect of the traditional clustering algorithm is to reduce dimension, while PPC don't need reduce dimension. Firstly, the text vector is normalized; Secondly, the project index function is constructed; Thirdly, the project function is optimized; Finally, the clustering result is acquired according...
Based on the research of traditional assessment structure and informatization, we propose a novel five-unit assessment structure. It includes data state unit, index system unit, assessment system unit, results feedback unit, management services unit. This paper describes the content of five-unit assessment structure. Compared to traditional assessment structure, the five-unit assessment structure...
The new generation of R&D personnel has unique personality characteristics and work values, which brings challenge for the human resource management in enterprises. Based on the literature analysis and in-depth interviews, this paper puts forward a five-dimension model of work values for the new generation of R&D personnel and makes an empirical test through the questionnaire survey and statistical...
With the constant development of economy in our country, food production enterprise credit consciousness and quality level had the very big enhancement, but the phenomenon of lack of credit is still outstanding. Food production and the establishment of the enterprise credit evaluation system is a system engineering, can fundamentally to ensure food safety in our country. This article from the perspective...
Problem of intranet security is almost birth with network interconnection, especially when the demand for network interconnection is booming throughout the world. The traditional technology can't guarantee the access terminals to its safe and reliable. In view of this, this paper introduces the trustworthiness evaluation technology in trusted computing. The collection and management model is established...
At present, the academic circles lack research of employee performance management for tourism planning companies, according to the concrete investigation of nine tourism planning companies in Beijing city, employee performance management as the research object, improving the management level as the target, combine with the basic theory and method of performance management, and on the specific situation...
For managing carbon emission, micro-generation with different capabilities are being actively explored for grid integration. Such small scale generation connected to low and medium voltage conventional network that are not designed to accommodate distributed generation pose various issues like voltage rise during off peak hours. The aim of this paper is to evaluate different inverter control strategies...
Accurately obtaining readers' satisfaction is great significant to improve the service level of library, on the basis of the United States Libqual+TM evaluation system, we design the readers' satisfaction survey of one university library in Yunnan. then we divide the research data into two parts, one part used for exploratory factor analysis, extract the factor of the library readers' satisfaction...
Building contractors have many risks to face. we took the multi-level comprehensive evaluating method of gray relational analysis and effectively resolved the problem of index weight in system, the comprehensive relational degree from this study gave a basis to evaluate building contractors' risks scientifically.
A learning style index is a model that can help learners to identify their learning preferences and hence adopt suitable learning materials that can enhance their learning process. On the other hand, teachers also can gain by knowing their students' learning preferences. It helps them to prepare a suitable teaching styles and materials that can fit with their students' preferences. This paper is concerned...
