As a common software engineering practice, software dynamic defect models are used to estimate and predict the software testing process progress, effectiveness, and the number of future defects over the next weeks. Practitioners use these dynamic defect models to ensure that the delivery of software to customers is possible from the quality point of view and to predict the release date. Old literature...
This paper is concerned with the evaluation model of emergency capability evaluation for the ship at sea. The goal of our work is to find the human reasons leading to the poor ship emergency capability, and then improve the team cooperation ability in emergency to avoid the vessel accidents. In this paper, firstly, according to the special attitude of the ship on sailing, the emergency capability...
The computation of a peeling order in a randomly generated hypergraph is the most time-consuming step in a number of constructions, such as perfect hashing schemes, random r-SAT solvers, error-correcting codes, and approximate set encodings. While there exists a straightforward linear-time algorithm, its poor I/O performance makes it impractical for hypergraphs whose size exceeds the available internal...
In this paper, we study a modified Leslie-Gower predator-prey model with Holling II type functional response and harvesting terms. By means of the generalized continuation theorem, sufficient conditions for the existence of at least two positive periodic solutions of the model are established.
In the future information warfare, the new military revolution whose core is information technology will makes the main body of war multiform, the area of the battlefield multidimensional, the battle element more integrated, the battle action associated, the form and model of equipment support much different. The ammunition support is crucial to form the combat power of the army as an important part...
The issue of navy vessel's overall system and life-cycle effectiveness-cost analysis is presented. The life-cycle's composition of navy vessel and the procedures of effectiveness-cost analysis are explored, and the difficulties of overall effectiveness-cost analysis aimed at whole life cycle are analyzed. On this basis, the simplification rules of effectiveness and cost are proposed respectively....
Modified Cambridge model has widely applications in analysis of soft soil, and the parameters are always obtained with some extra soil mechanics experimental. Here we summarizes some methods to estimate the parameters of modified Cambridge model without extra experiment. With these methods we could estimate every parameter of modified Cambridge model just through the general geotechnical investigation...
The most challenging problem in the heterogeneous wireless networks is ensuring seamless network selection. For that reason, a large variety of algorithms based on multi attribute decision making (MADM) have been proposed to deal with this issue. The analytic hierarchy process (AHP) and the technique for order preference by similarity to an ideal solution (TOPSIS) represent two MADM methods which...
In this paper, the voltage stability in power systems with economic dispatch (ED) problem is investigated. Also because of increasing the number of wind generators in power systems, they are considered in this investigation. For this purpose, with ED equations and equality and inequality conditions, a voltage stability index is considered. This index is considered as an inequality condition by optimization...
With regard to the frequent food supply chain risk incidents situation, This paper divides the hierarchical structure of food supply chain risk factors with F-AHP, and buildes a food supply chain risk factor identification system and risk fuzzy comprehensive evaluation model on the basis of definition of food supply chain. Meanwhile, by taking the food supply chain of one diary producer for example,...
By using the method of factor analysis and regression analysis, the national physical data of 2000 and 2005 were disposed by SPSS13.0 software (the national physical data of 2010 is unknown now) and the physical monitoring model of the adult in Shijiazhuang was established by taking the physical data of male from 20 to 25 years old as an example. The national physical condition of adults in Shijiazhuang...
Taking 22 Chinese Taibei men volleyball players as the subjects, we have tested 16 physical quality indexes related to the players' leaping abilities. A “0–1 program” is used to filter the tested figures according to such indexes and the selected ones will be examined by multiple regression analysis to establish the regression model. It has been tested that this model is of statistical significance...
In order to reveal internal marketing effect in China's Star hotels, structural equation model (SEM) is used in this paper. By employee satisfaction index system, customer satisfaction index system, data collection and model validation, SEM can effectively reveal the effect of internal marketing of the hotel industry. For illustration, 276 samples were selected from seven provinces and cities, in...
In the process of New-countryside construction, green community is a developing mode that can harmonize economic factory and ecological factory. New-countryside green community's design was influenced by many factories, such as humanistic image, ecological image, economic conditions, etc. Structural equation model (SEM) is known as covariance structure analysis or linear structure modeling. It can...
Since the establishment of a managed floating exchange rate regime, the fluctuations and the movements of RMB exchange rate are increasingly becoming a major concern of scholars and politicions. In this article, the sources of pressure on the RMB exchange market are quantitatively analyzed based on the Girton-Roper model and its extensions. The results show that the growth rate of domestic credit,...
The coal industry as the basis for the national economy sectors, the financing of its debt maturity structure of listed companies on the development of China's coal is significant. In this paper, our object of study of coal listed companies, the use of multiple regression analysis,to research the coal company's debt maturity structure listed the factors affecting, obtained through empirical testing...
This paper analyzes the influence factor of service quality in quality certification corporations, and bring up the hypothesis relationship between auditor's service quality and center's service quality in the service process of quality certification, taking a certification center as an sample to unfold the empirical study, and establishes its outside quality structure equation conceptive model, through...
Aiming at the problem being too complex for the present evaluation methods on water resources carrying capacity, a new method, improved set pair analysis model was used to solve the complicated non-linear relation between the evaluation factors and water quality grade. The model was applied to evaluate water resources carrying capacity of 12 farms in Sanjiang Plain and the results of the assessment...
The relationship between environmental performance and economic performance is the core problem of environment management. The relation is also very important in environmental management accounting (EMA). The paper designed questionnaire which is based on Wager's (2003) sustainability performance relate to business competitiveness. We use SPSS software to analyse, we demonstrate that the effects of...
Based on the results of the fact — finding visit, this paper established a comprehensive directed weighted evolving network model that integrated fitness-based preferential attachment, node deletion, link establishment and link deletion, and performed analytical deductions. Then the in-strength distribution index is taken as the main object of study, this paper validated the model respectively when...
