In order to modelling and managing software process resources, this paper first divides software process resources into four categories. Based on the classification, a formal software process resources model (SPRM) is proposed. The model support modelling resources into the four different categories, describing the nature of the resources by define first-order predicate formulates, restricting resources...
Recently there has been rapid development of large-span and shallow-buried highway tunnel construction and considerable risk appear, the urgent issues are that how to identify effectively risk factors which in the process of tunnel construction. With the review of disadvantages of risk recognition methods, the risk hierarchical structure for construction of the tunnel was established using the Analytic...
Based on the elastic foundation beam method, m values for deep excavation were back-analyzed by using a constrained no-linear optimization method in MATLAB. The horizontal displacement of diaphragm wall during excavating was used in back-analysis procedure. The case studies in Suzhou subway showed that the presented method is simple and feasible. The m values obtained can reflect the actual situation...
Adopting Hardening-Soil finite element model based on unloading ,the improvement of grouting strengthening rear soil on deformation of the pit is studied. The results show that the reinforce influence on lateral deformation increases with the increasing of the excavating depth, the final lateral deformation reduces 13.6% than without reinforce, the displacement of pile top reduces 40.66%, but the...
Widely using of the CAN bus makes testing on it be a regular method to guarantee its performance. Current methods of testing CAN bus mainly identifies its data frame acquired from the link layer interface chip. Method of physical layer testing makes transmission performance test of CAN bus network and fault location to be possible.
The number of listed companies in the ceramic industry in China stock market is very small, but represents the development situation of the whole industry. Evaluation on the performance efficiency of the listed companies is very important. Traditional AHP and DEA evaluation methods face problems of subjectivity or lack of human factors. A combination method which integrates advantages of the two models...
Research of synthetic aperture radar (SAR) for Moving target detection and imaging has huge value of military and civilian, a great many of countries are seeking to study motion detection and imaging technology, and to seek efficient and practical method and new system. especially to study the ground of moving target detection and imaging (SAR / GMTI) technology, With the development of airborne SAR...
Software process play an important role in improving the quality of software products. Formal software process model is conducive to the accurate description of software processes. A software process meta-model is a formal tool used to define software process models. In this paper, a software process meta-model SPMM is designed. Firstly, five important properties in software processes are discussed...
VRGIS is a production of combining Geographic Information System with virtual reality technology, and it is also a research hotspot in this two areas. However, the real-time features for Virtual Reality Geographic Information System have been seriously hindered in the development of practical application and popularization. If we simply add fog particles into the 3D Geographic Information System scene...
In the Group agreement, the cluster heads' distribution is irregular and the data path is not the best, so it is necessary to design a better routing protocol. Based on the method of “distance becoming zero”, a grid clustering routing protocol is designed, and the simulation comparison is completed between Group agreement and the improved grid clustering routing protocol.
With development of internet and database technology, web mining has got more and more attentions from information science domain. This paper proposes a document clustering technique based on term clustering and association rules. In this technique, extract words from document collection firstly, then construct term clustering according to AMI(Average Mutual Information) between terms, document VSM(Vector...
During recent years, electronic business industry has been developed rapidly. Some companies in the industry have been listed on the security market overseas or in the domestic. They have achieved excellent performance in the stock market, and given great value returns to the shareholders. Chinese economy is experiencing an important period of transforming industrial and economic structures. More...
In the filed of software process modeling, there are a lot of software process meta-models and software process modeling languages to define software process models. The main difference between them is that software process meta-models define an abstract syntax of software process models, while software process modeling languages focus on a concrete syntax. However, they do not take into account a...
Since B-to-B commercial websites play a decisive role in electronic business and trade, the evaluation and selection of them are very important. There have existed many methods for evaluation on commercial websites nowadays. But there are very few patterns of evaluation that are widely recognized and accepted so far. To tolerate subjective and objective factors that might influence evaluation results,...
Electronic paper book (EPB) is a brand new concept and product different from traditional electronic readers. In the recent two years, from technology to product, EPB has been developed rapidly, creating a prosperous market. EPB means a great milestone-like revolution for both the information content industry and high tech manufacturing industry. EPB undoubtedly has many strengths Compared with traditional...
Focusing on the problem of image details losing while denoising image using Median filter method, the article proposes a salt and pepper noise filtering algorithm basing on grey system theory. The algorithm employs the idea of sorting out current pixel firstly and then filtering, where all the pixels are classified into two groups, according to the noise characteristics, one is suspicious noise and...
With the acceleration of urbanization in our country, small town construction is facing various kinds of difficulties and problems, and the importance of developing the circular economy of small towns is increasingly significant. Although the construction of demonstrative small towns in Tianjin has been in the front ranks in the country, the speed and scale of the development of circular economy are...
The issue of the top management motivation has been a hot topic in the fields of business administration and company governance in recent years. Under the intense competition of the market, the motivation of the top managers has become extremely important to maintain the durable competence and the long-term development of the company. At present, state-owned enterprises are facing an uncommon developing...
In the Component-Based Software Development process, component is the basic unit of software reuse, the component evolution is to be composed of a series of complicated change activity. In this paper, we give a fine-grained component from the angle of interface, and give out a series of formal description. Further more, the detailed discussion and analysis of component behavior relativity are presented,...
Compared with traditional Fast Fourier Transform (FFT), modulation FFT preserves its characteristics of low complexity when used to estimate the frequencies of real-valued signals. But there are spectral leakage and picket-fence effect, frequency resolution is still difficult to achieve high accuracy. Multiple Signal Classification (MUSIC) algorithm can achieve high frequency estimation accuracy,...
