The assessment of photovoltaic technologies using multiple perspectives such as social, technological, economic, environmental, and political (STEEP) have become increasingly important in the last several years. Each perspective is composed of multiple criteria with the social and political perspectives gaining more significance. A hierarchical decision model using expert judgment quantification was...
The electric power industry plays an important role in the economic development of China. It is not only an important fundamental energy industry in economic development, but also one of the important sectors promoting the economic growth and social progress of China. The economic value of this industry is reflected by the electric power industry as well as upstream and downstream industry chain closely...
Net metering is a widespread mechanism which enables consumers to reduce their electricity bills by utilizing self produced electricity from renewable energy resources, it also allows the power producers to sell the excess energy produced to utilities or grid. Photovoltaic system is used widely in net-metering for residential implementation. This study is a feasibility check for implementing net metering...
The electric power delivery system was designated by the U.S. National Academy of Engineering as the leading engineering development of the 20th century. This engineering marvel is being further updated with new technologies to realize a smarter electric grid. The smart electric grid will be more controllable and interactive compared with the existing electric grid. With growing complexity, there...
In this paper, we extend the Baum and Katz theorem in the condition of independent, and obtain the specific forms of expression of Baum and Katz theorem in the case of exchangeable random variables.
The trust problem has been a hot issue in the current grid research. In order to solve the security problems which grid's dynamics and uncertainty bring, a new trust model is proposed to deal with the trust relationship between entities. Different methods are adopted to deal with trust relationships inside the domain and between domains in the model. In the calculation of the trust, not only the free...
Before matching the video frames in Scale-Invariant Feature Transform (SIFT) algorithm, the key-points must be extracted firstly. If the size and characteristic of input images are changed, gray threshold of key-points must be reinstalled, to avoid extremely computation cost or failure in registration. In this paper, a self-adaptive SIFT key-points extraction algorithm for video images is developed...
This dissertation was based on the structured programming approaching to system development, using technology based on C #, ASP.NET, VS2005 and SQL Server 2000 database software, to build the plants information management system for hundreds of existing plants in HengShui University campus. The system design not only included add, delete, modify, query, statistics and other basic functions but also...
By canonical transformation, multisymplectic systems and multisymplectic conservation laws for nonlinear Good Boussinesq equation with periodic boundary conditions are obtained. Using sine collocation method in spatial direction and Euler centered scheme in time direction to the multisymplectic systems, a multisymplectic sine collocation scheme is constructed. At the same time, we have also obtained...
This paper studies the a posteriori error estimate of residual type of the Q1rot element for the Steklov eigenvalue problem and gives the a posteriori error indicator and the Matlab program of computing the a posteriori error estimate Indicator η2. Numerical results indicate that the a posteriori error estimate indicator is efficient.
This thesis introducing XML technology and SOAP technology, present an agent communication framework based on XML and SOAP technique, and analyze the principle, architecture, function and benefit of it. At the end, based on KQML communication primitive languages.
This paper has mainly introduced the solar power engineering of Yellow River Conservancy Technical Institute. For this solar power system, its economic feasibility and functions in teaching and scientific research were analyzed, and its affect in energy conservation and environment protection were elaborated. Those analysis results show that it has multiple functions and good social and economic benefit,...
This paper introduces the new notions of b-I-open sets in the ideal topological spaces, and uses them to define b-I-continuous mappings and b-I-compact (b-I-paracompact) spaces. And also have some characterizations and several properties of them.
In many practical problems, it is sometimes necessary to evaluate the derivative of function whose values are given approximately. In this paper, we consider the problem of estimating the derivative of a function observed with error. We present a proper regularization strategy and explain how to choose regularization parameter. In the end some numerical examples will further illustrate that this method...
Bifurcation of limit cycles for three perturbed integrable non-Hamiltonian systems is investigated by using both qualitative analysis and numerical exploration. The investigation is based on detection functions which are particularly effective for the perturbed integrable non-Hamiltonian systems. The study reveals that each of the three systems has 4 limit cycles. By using method of numerical simulation,...
This paper introduces the new notion of weakly-α-I-open set in the ideal topological space. And the following important result is obtained: weakly-α-I-open sets constitute a topology of the ideal topological space X.
As our world's competitive global economy continues to development, Chinese software industry, though enjoying an impressive growth. Therefore, it is an important issue for decision makers to evaluate each of the local software industry development and put in the corresponding development policy. This paper, based on aggregative rank, analyses the local software industry operating income and get the...
It is important to reason about the possibility of certain events as well as the knowledge of agents in many of application areas for reasoning about knowledge. This paper proposes the concept of belief degree of an agent i with respect to a fact. Moreover, based on the belief degree of agent i, the similarity degree between agent i's graded knowledge and a pseudo metric on the set of agent i's graded...
In this paper, we apply the soft set theory intruduced by Molodtsov in 1999 to the theory of MV-algebras. For this, the notion of soft MV-algebras and soft MV-subalgebras are introduced and some related properties are derived.
Taking water-solubility preservative(ACQ-B) as the agentia, and the liquid medicine concentration (LMC), the forcing time, the liquid medicine temperature(LMT) and the pressure as the test factors, the permo-treatment was processed to the circle bamboo, and the technical conditions of the treatment were compared. The results showed that each factor and the levels in the same factor had all larger...
