Objective quality assessment plays a very important role in the video applications, as they promise the means to evaluate the performance of acquisition, display, coding and communication systems. Objective video quality assessment still has a long way to go before it reaches the level of success. In this paper, we propose novel quality metrics for video sequences. These metrics are capable of capturing...
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...
We present a novel method, which reads the database at regular intervals as in dynamic itemsets counting technique and creates a tree called dynamic itemset Tree containing items which may be frequent, potentially frequent and infrequent. This algorithm requires less time to discover all maximal frequent itemsets since it involves a method for reducing the size of the database. This method prunes...
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...
Firewall played an important role as a tool that protects the network of the enterprise. On optimizing firewall policy, firewalls can filter packets effectively and improve the performance of firewalls. Otherwise, if a firewall policy is not written properly, firewall will easily become a fatal point of network attacks. In this paper, we first propose a statistical model that statistic packets which...
By communicating and information exchange, agents can fulfill goals of multi-agent systems. Different communication languages and protocols have been proposed for agents. These languages are designed to transfer high level data and donpsilat have appropriate efficiency to send sensing. hearing and visual information in real environments. In this paper a model to exchange such kind of data in an efficient...
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...
Human-computer interaction (HCI) in embedded system is an issue concerned by many people. From the engineering point of view, by analyzing the scenario of embedded system, we propose the use of multi-list for HCI in embedded system. We have set up the model and implemented the system. Our engineering practice shows the effectiveness of this scheme.
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...
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...
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...
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...
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...
This paper presents the implementation of a tightly coupled hardware architectural enhancement to the Altera FPGA-based Nios II embedded processor. The goal is to accelerate Advanced Encryption Standard (AES) operations in 128, 192 and 256-bits, for application in a high-performance embedded system implementing symmetric key cryptography. The concept is to augment the embedded processor with a new...
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...
Due to the rapid increase of population and the necessity of providing adequate drinkable water supplies, which meet hygiene conditions, modern techniques are applied for water treatment. In particular, this study introduces a flexible model for describing, calculating and estimating the volume of water in distribution tanks through all phases of treatment processes. The model considers a typical...
Sustainable development is widely practiced by many engineers, academicians and policy makers for making the industries environmental friendly, to obtain sustainability in any industry there are many methods. Resources utilized in an industry should be identified properly in various processes and its utilization is to be optimized to increase the environmental performance of the industry. Ecomapping...
