Curvature reflects the size of bending degree of curve. In this paper, we put forward a new relational degree model based on curvature of the two series. The new model satisfies the parallel property and uniform property. It is consistent with the actual situation by comparison to the existing relational models. At the end, we give a case in order to validate the new model.
In order to provide a quantitative tool in how governments supervise food corporations, this paper constructs game model between governments and food corporations when there is prosecution existing in the food supply chain. We can reach the pure strategy Nash equilibrium solution and the mixed strategy Nash equilibrium solution in different circumstances, and then contrast the differences of game...
As has been widely reported in the news lately, healthcare errors are a major cause of death and suffering. In the University of Massachusetts Medical Safety Project, we are exploring the use of process modeling and analysis technologies to help reduce medical errors and improve efficiency. Specifically, we are modeling healthcare processes using a process definition language and then analyzing these...
Based on the perspective of demand motive of foreign exchange reserve, this paper constructed the measurement model of moderate scale of foreign exchange reserve based on multi-level demand and selected the actual data of China for measurement. Results have shown that the moderate interval of China's foreign exchange reserve was between 900 billion, and its excess scale was about...
According to the situation that creating fault tree manually is inefficient, error-prone, existing software of visual fault tree modeling is not perfect, not easy to transplant, research visual modeling and analysis of the fault tree. First, this paper discusses the visual building method combines dynamic contribution with stratified achievements, fault event editing functions, separation of fault...
Quick and highly efficient warning is critical in any emergency evacuation. From the issuing of warning until action taken by people in response, the entire course is a very complex process which is restrained by social, economic, population and other factors. To study the diffusion characteristics of warning in the social network environment as well as the relevant influencing factors, under the...
According to the characteristics of construction project, the risk evaluation of complicated construction project is converted into the evaluation of four indexes including duration risk, cost risk, quality risk and safety risk. Establishing the fuzzy and grey correlation analysis model with the combination of the fuzzy theory and the grey correlation theory, fuzzing the judgment of specialists on...
In order to realize the full rang of information security, a variety of network equipment, safe equipment have been applied to deal with all aspects of information security and protection by many enterprise. These devices, systems produce a lot of security event log in the network security protection, and these event log data format are different, and different safety equipment may generate the same...
Owing to its advantages of rapidity, convenience, and cost-effectiveness, on-line shopping is becoming one of the favorite shopping method for university students. And because of consumption characteristics, the web consumption behavior of university students as a special group of consumers has special manifestations and particular determinants. Based on a survey of university students' on-line shopping...
Nuclear power around the world has shifted to expand the lifetime of nuclear power plant as long as possible on the condition of safety and reliability instead of constructing new ones. In order to achieve the goal of life extension, the nuclear power plant all attach great importance to the life cycle management of critical equipment. LEA is a core of the life cycle management of critical equipment...
This research takes the safety inventory and the uncertainty of supply and demand in inventory distribution network into consideration, establish the reliability model and supply-demand distribution model, and demonstrates the feasibility and practicability of the model which is used to solve problems of reliability of supply-demand distribution in spare parts inventory distribution network.
Quantification of Margins and Uncertainties (QMU) is a methodology for assessing the confidence in the performance of complex systems, and has been applied to general engineering areas. In this paper, the concept and process of QMU is introduced at first, and then an implementation framework of QMU is proposed for structural analysis considering uncertainty. The framework is a synthesis of several...
Conventional methods for safety analysis have problems in terms of correctness and efficiency. Using formal methods and fault injection techniques can improve consistency and correctness for safety process throughout the system's safety lifecycle. Yet existed methods for fault injection and safety analysis mainly think about single faults injection for system, seldom do with fault injection for multiple...
Vehicular Ad Hoc Networks (VANETs) and their diverse applications experience growing interest in both academic and industry. Different types of traffic packets delivered through vehicle-to-vehicle and vehicle-to-infrastructure communications are intended to improve passenger safety and comfort. In this paper, we propose a multiple priority supported Medium Access Control (MAC) protocol for VANETs...
The main components of the inventory control system are analyzed. The dynamic inventory control model of vulnerable articles is built by focusing on the characteristics of the vulnerable articles, introducing the lost time and loss factor of articles to calculate the inventory loss cost and on the condition of considering the bulk price discount and safety inventory, etc. The model has been verified...
This paper presents a novel approach, based on static analysis, to detect format string vulnerabilities in C programs. Format string vulnerability is viewed as a finite state safety property. The analysis is expressed as a system of constraint describing how the safety state at one program point is related to the state at adjacent program points. Our analysis is inter-procedurally flow sensitive and...
GIS Crime Analysis System is designed for the purpose of crime analysis, crime investigation and crime tracking with technical support and decision support for the police staff. Since the system's data is sensitive and secret, it's very important to ensure the safety of information and authentication of the user's identification. This paper presents architecture of GIS Crime Analysis System based...
Waste dumping is one of the main pollution causing land deterioration and resource depletion. To help manage the environmental protection resource, this study proposed the risk assessment integrating remote sensing and geographic information system (GIS) to predict and map potential waste dumping area. Factors relative to waste dumping were generated with spatial analysis, which quantifies the spatial...
This article has a research on four representative student residence's design project from four aspects through AHP method looking forward to revealing future dormitory planning, designing and building.
In this paper, the existing products' status about mechanical life-saving parachute device or unlock device is analiszed, and the key problems in specific design of multistate program control parachute is shown and illustrated. The prototype is development, which is formed mainly by PC104 as control core, 3-dimensional electrom compass as sensors and ball lock mechanism as release machine. Princinple...
