Wind is strong at the site of Jing River Bridge, the effect of wind load and other possible loadings on the stability of the structure is considered. Based on the actual construction stage, this paper mainly analyzed the nonlinear stability of No.6 and No.7 piers of the Jing River Bridge. Material nonlinearity and geometric nonlinearity are both included in the numerical investigation. The results...
To know deep foundation pit state and ensure its safety, multi monitoring points data are used to establish model in a quick and useful way. Considering grading excavation effect, time effect and synchronous multi-point displacement monitoring information, the frame of Radial basis function artificial neural network (RBF) multi-point monitoring model has been structured. The concise effect factors...
In this thesis, Firstly, some properties of self-orthogonal Latin square are studied. Secondly, the exists of v-self-orthogonal Latin squares of order v is proofed . and then several special constructions of v-self-orthogonal Latin squares of order v are provided. Especially , It have the specific DOP set. and recursive construction is used to generate the v-self-orthogonal Latin squares.
Core competence is the base to get competitive advantage for sustainable development. The elements to form core competence are put forward according to the implication and primary features of power supply enterprise in this paper. The index system and its evaluation model are built based on six composition elements such as economic benefit, marketing services, development capability, work safety,...
In view of fuzziness of university teaching quality evaluation, AHP-based multi-level fuzzy comprehensive evaluation model become the advantage model for university teaching quality assessment. It is of great importance to evaluate scientifically teachers' teaching quality in the classroom. The methods of AHP and Fuzzy comprehensive evaluation are applied to evaluation of classroom teaching quality...
User interfaces often behave unpredictably on erroneous input - rather than blocking errors and requiring the user to correct them. The consequences of this in the context of medical devices, which may give patients undetected overdoses, can be unfortunate. The solution should include better design, including the concept of safety locks, that block some forms of user error.
An algorithm for bending robots is presented in this paper. The algorithm makes use of the features of bending process to solve three problems: procedure generating, targets calculating and obstacle avoidance. It generates procedure with two state machines and a knowledge library, calculates targets with heuristic rules, and avoids obstacles in joint space. The algorithm has been applied to manufacture...
Based on appraisal methods of land capitalization rate and expert opinions of standard land price evaluation, this paper proposes for the first time an ANN model to evaluate land capitalization rate and it proves that these models have better abilities to simulate expert appraisal.
WSN (wireless sensor network) is of low cost, low power, small volume, high redundancy and multi-function, which make it more reliable and effective for targets locating and precision guidance than traditional ways. The structure for this particular use is designed in this paper, and the budget, energy, safety, anti-disturbance and transmission distance problems are analyzed. Simulation of a simplified...
Nowadays, the requirement and market of children product is accordingly enlarging in pursuit of humanized design. How to design the product which answers for the physical and mental development of children is becoming more and more important. This paper analyzes and sums up the characteristics of eating behavior of children during early childhood as well as their cognitive characteristics by a series...
Metro, as a most effective measure, play an important role to alleviate the traffic pressure, also is one of most important characteristics of the identity of city. According to the research result of European industrial association, from 2005 to 2015, globe metro market value increases 2.7% every year, especially focus on developing countries, facing this complexity, this paper tries through the...
TOC thinking process tools are unique in their ability to improve safety performance in enterprises where the heavy economic losses and casualties occur due to a variety of health and safety accidents. Safety management is a very complex system that includes human, machine management, and environmental factors. Therefore, it is challenging to improve safety performance. Thinking Process (TP) is a...
Before assessing the desirability of nuclear power we first need to narrow down the focus on its potential and its impediments. Within the technological possibilities of nuclear power production, I shall formulate two prima facie duties for safeguarding the interests of future generations: (1) to ensure that they have access to at least the same resources as we have and (2) to ensure that the burdens...
The evaluation of the road traffic safety management is affected by many factors, which are related to the management of road traffic safety. Combining with the fact of Chengdu city, this paper establishes the evaluation index system of road traffic safety management, Based on abundant investigations and interrelated information of document, it operates the single-item evaluation with the means of...
The security of maritime traffic is a significant part of intelligent maritime traffic. It can reduce to ship manipulation and collision avoidance by macroscopic. Eighty percents of marine accident induce by human factor from research data. So some researches about computer evaluation system inducted to ship manipulation and collision avoidance to reduce the accident of human caused. Evaluation system...
Coal gas drainage out of the mine excavation workspace is the urgent problem to be solved for safe production, a novel double mode fuzzy control strategy of gas drainage system for the coal local ventilator is proposed in the paper. One fuzzy control mode is used in normal aeration state. The other mode is adopted to expel the gas from the mine well, when the gas strength is abnormal. The switching...
Web applications can only be accessed through dedicated client systems called Web browsers. Most current Web browsers offer many tools or facilities for Web page revisiting, including the back and forward buttons, refresh, favorites, link menu and history lists etc. Users can press the back or forward buttons to negatively influence the behaviors of Web application navigation. Existing navigation...
The nature of flight risk assessment has always been a problem of uncertainty. In order to quantify the risk somehow is important. Based on the previous related studies of airlines flight safety assessment a new flight risk assessment index system was built in this paper. Bayesian belief networks model with diagnostic and predictive inference was proposed to evaluate flight accident probability on...
This paper is dedicated to come up with theoretical expressions of increasing demand for Knowledge discovery in databases (KDD) in management of digital sport facility in the context of which, China is on the verge of Beijing Olympic Games. And it presents a number of aspects for rethinking the concerns involving the process in order to realize the close relationship between information management...
To improve the effectiveness of the database system in the development of Dam Safety Monitoring System, combing with a development project whose database model is based on multi-dimensional model principles, elements of dimensional database model have been interpreted intensively such as factual tables, dimensional tables, star and snowflake modes and so on. Then modeling principles and process are...
