In this paper we study the power line fault probability considering various meteorological factors. The calculation of the real-time fault probability of transmission lines is an important part of on-line risk assessment and real-time reliability calculation of power system. First, we study the fuzzy member function of various factors. Uncertainty theory is adopted to determine the weight coefficient...
This paper shows that a comprehensive multivariable approach of autopilot design that mixes sliding mode and PID leads to robustly satisfactory results for underwater mobile robot. The 6-DOF linear equations of motion can be divided into three subsystems for speed control, steering, and diving. The sliding mode algorithm is designed for steering control and PID is used for diving and speed control...
To efficiently preserve tiny details and sharpness information of synthetic aperture radar (SAR) images while clearly remove the speckles, a despeckling method is proposed in this letter. Firstly, the SAR image is creatively separated to two parts: the texture region and flat region by using the decomposition with non-subsampled contourlet transform (NSCT) and mask estimation iteration algorithm....
A method using autonomous surface vehicle (ASV) is presented in order to track autonomous surface vehicle (AUV). This method uses tracking control based on chasing activity. The heading and speed of ASV is automatically adjusted according to position and speed of underwater robot. And the safe domain of ASV which is not allowed to get out of is built to avoid danger. Sample points are updated dynamically...
The application of LabView multithreading technology has realized the high-speed data collection based on CAN (Controller Area Network) Bus and the real-time online monitor for battery system based on Excel applying dynamic link library, operational control and many other technologies. Meanwhile, it provides the function of the historical data records, which offers important reference for the operation...
Shenzhen is a quickly growing city of immigrants. The diversity of its inhabitants' cultural backgrounds formed a diversity of social and cultural atmosphere, and culture circle of immigrant appeared in ShenZhen. It's the characteristic culture of ShenZhen, and worthy of protection in urban renewal. Based on analyzing the spatial characteristics of different immigrant cultural circle in Shenzhen,...
This paper researches on the non-English postgraduates English learning in universities of science and engineering in Hebei province through questionnaire surveys and experts' evaluation. Then with an assessment system of postgraduates English teaching based on AHP it establishes, the paper evaluates 5 universities in Hebei province and proposes the corresponding suggestions.
The thesis attempt to propose an 'Urban Waterfront Greenway System' (UWGS), in order to create a healthy, abundant and efficient life circle in urban waterfront. It aims at how to make full use of the urban waterfront, which acts as the interest origin, to guide the healthy life style at first. States the concept of 'interest gravitation', points out it is the power and emphasizing its importance...
The urban design of Internet era calls for a new lifecycle mode of health and sustainability urgently, which is able to satisfy the demands of efficient life, and at the same time access to experience the real human nature, in order to integrate the fast and low rhythm of life, and finally finds the realization approach of new life, care life, health life, beauty life, and enjoy life. From the perspective...
Most traditional methods to deal with the floods in the waterfront area are planting trees, building dams, leading and dredging canals. And all these methods have played an important role in ensuring the urban safety. In this paper, we concentrate on the urban waterfront area design and introduce the concept of greenway based on the three traditional approaches. We develop a new framework in the flood...
Google Earth is a very popular virtual globe program, famous with providing abundant resources of remote sense images all over the world, which has been widely used in many industries. Therefore, the application of high resolution satellite image and the changing of Web to development tool of geographic information services are the directions of urban planning and design services in China. The thesis...
This paper is researching on how to guide people to develop low-carbon trip habits to achieve traffic mitigation in the field of energy conservation through urban design. Global warming caused by carbon emissions makes human survival and health be threatened, and low-carbon urban design is imperative. Carbon emissions in the area of Traffic growth year-on-year, and it is difficult to control because...
In view of the complexity and synthesis characteristic of urban design, we propose an effective method - "Basket-Cabinet Methodology", which exists in the public information management domain to deal with the complicated problems. Base on the concept of this method, we construct its space model, and point out that it has intuitional, scientific, multiplex, and flexible features to be suitable...
This paper introduces an application research on taxi calling and dispatching system (TCDS in short), which is a prototype of LBS application based on GPS mobile phone. The paper gives the basic design, modules division, GIS display algorithm design, test results and feature analysis of TCDS prototype. Finally, the paper points out the further improvement direction of TCDS, and prompts its usage in...
