The natural resources management area is substantial to the development of the all countries, because the resources are more scarce and the number of people bigger. For these reasons, they are more difficult to manage. In this way, find good techniques to learn how to treat with these resources in a sustainable way is an important activity of sciences. Specifically in computer science, several works...
Software evolution is an important activity in software life cycle. The Web application is very different from traditional software in design and composition. It needs maintained more frequently. So the automatic evolution support is a critical part in Web engineering. This paper uses Markov chain to model Web userspsila browser behavior by statistic analysis of Web log. And transition probability...
In the last few years, several Web-based conference management systems have been developed and used by many international conferences. However, almost all of them were built on stand-alone Web servers. Their fault tolerance, scalability and ability of responding to dispersed users are limited. Aimed at addressing these problems, this paper presents a novel approach for Web-based conference management...
Services are offered by service providers, which procure service implementations and maintenance, and supply service descriptions. For Web services to become practical, an infrastructure needs to be supported that allows users and applications to discover, deploy, compose and synthesize services automatically. The essence of the Web service is the process on marching between the userspsila request...
Regularization plays a vital role in ill-posed problems. A properly chosen regularization can direct the solution toward a better quality outcome. An emerging powerful regularization is one that leans on image examples. In this paper, we propose a novel scheme for face hallucination. We target specially the quality of highly zoomed outputs. Our work bases on the pyramid framework and assigns several...
In this paper, we proposed a method to transform the workflow processes into CCS, and the workflow process is described in activity network charts. For the first, we used CCS to describe the six basic logical relations of the workflow model, and then based on the basic expressions, we illustrate how to transform the whole workflow model to CCS process expressions.We provide the exact formalization...
In this paper, we propose an efficient method for resolving the optimal discriminant vectors of generalized discriminant analysis (GDA) and point out the drawback of high computational complexity in the traditional class-incremental GDA [W. Zheng, "Class-Incremental Generalized Discriminant Analysis", Neural Computation 18, 979-1006 (2006)]. Because there is no need to compute the mean of...
Keyword extraction has been a very traditional topic in Natural Language Processing. However, most methods have been too complicated and slow to be applied in real applications, for example in web-based system. This paper proposes an approach which will complete some preparing works focusing on exploring the linguistic characteristics of a specific domain. This part can be completed once and for all...
The university course timetabling problem is a combinatorial optimization problem concerning the scheduling of a number of subjects into a finite number of timeslots in order to satisfy a set of specified constraints. The timetable problem can be very hard to solve, especially when attempting to find a near-optimal solutions, with a large number of instances. This paper presents a combination of particle...
We propose a general survivability quantification framework which is applicable to a wide range of information system architectures and applications. We show how this framework can be used to derive survivability measures based on different definitions and extend it to other measures not covered by current definitions which can provide helpful information for better understanding of system steady...
In the paper, we introduce a music knowledge question answering system based on ontology knowledge base. Users can propose a question about music knowledge in natural language, the system automatically extract relative knowledge to form answer based on FAQ (frequently asked questions) and ontology knowledge base, and return the answer to users in natural language. The important modules in the question...
This paper analyzes the suburb tourism trend based on system dynamics method. It applies SD (system dynamics) method in system analysis, which starts with problempsilas structure and discarding trivialities. An empirical study is made to find the trend of suburb tourism due to new holiday policy. The finding of this paper is very useful for local authorities who want to facilitate the development...
According to the actual situation in the integrated statistical work of coal enterprise in our country now, we determined using the exploitation method of combining SAD and object oriented by analyzing the system's function characteristic, has established the composite structure model which C/S and B/S unify. The system has realized many essential functions such as the technical specification dynamic...
Computer-assisted assessment of summary writings is a challenging area which has recently attracted much interest from the research community. This is mainly due to the advances in other areas such as information extraction and natural language processing which have made automatic summary assessment possible. Different techniques such as Latent Semantic Analysis, n-gram co-occurrence and BLEU have...
Similarity-based search has been a hot research topic for a long history, which is widely used in many applications. The large scale restricted floating sensor (RFS) network is an important model in offshore data collection . This paper constructs a new fuzzy similarity measures based on distance. This work provides a theoretical guidance for constructing a fuzzy query processing strategy for our...
This paper is intended to present theoretical and implementation details of various important features that are generally associated with an Asterisk based Voice Exchange i.e. conferencing, paging and voice mailing. Besides this we will be concentrating on the web based approach for the configuration of the hard phones that will be used at the clients end. Our approach follows the client server model...
Non-dedicated computer clusters promise more efficient resource utilization than conventional dedicated clusters. Existing non-dedicated clustering solutions either expect trust among participating users, or they do not take into account a possibility of running multiple independent clusters on a same set of computers.In this paper, we argue how an ability to run multiple independent clusters without...
Multiprocessor task scheduling problem has become increasingly interesting, for both theoretical study and practical applications. Theoretical study of the problem has made significant progress recently. However, it seems not to imply practical algorithms for the problem yet. In this paper, the offline version of the Multiprocessor scheduling problem on m-processor system is discussed for the case...
Support Vector Machine has the convenient superiority in the classification. Recently it has been extended to the domain of regression problems. However, due to the increasing index, excess input data and complicated system structure, it is difficult to achieve good accuracy in results. This paper adopts combination method of rough set and support vector machine so as to establish rough set attribute...
Quantum-behaved Particle Swarm Optimization (QPSO) is a new particle swarm optimization (PSO) algorithm. Compared with standard PSO (SPSO), it guarantees that particles converge in global optimum point in probability and this algorithm has better performance and stability. This paper introduces an improved Adaptive QPSO algorithm, puts the parallelisms crude of AQPSO and high speed of computer together,...
