Using method of object-oriented design, integrated multithreading technology,...

With the development of network technology, computer networks are becoming increasingly popular in people's daily life. Computer brings us not only convenience but also potential problems caused by computer viruses. Most viruses are Win32 PE viruses. This paper firstly analyzes the Win32 PE file structure,...

Different from previous tree modeling approaches, our method is based on the idea of making tree reconstruction as quick as possible and simplifying the representation of final results while keeping the tree model visually acceptable. Each tree is represented by Billboard model. We first get the shape...

This paper presents a four-layer framework for distributed software test automation, which is composed of test component layer, test component management layer, test scheduling layer and test domain layer. According to the target of testing, the problem space of software test divide into several feature...

Multipath Transmission Control Protocol (MPTCP) can provide multipath communication end to end. It improve the utilization of network resources and network transmission reliability. In this paper, the receive buffer blocking problem[1],which is the basic problem in the MPTCP,is presented.A data scheduling...

Texture mapping is an important part of the realistic graphics rendering process. In this paper we parallelize the algorithm for traditional texture mapping to improve the running speed of the program. The experimental results show that, the speed-up of the program can reach to 1.92 in average.

Investment in securities is in an uncertain environment, any gains obtained are accompanied by certain risks. The essence of portfolio optimization is the optimal allocation of the limited assets in securities with different risk and return characteristics. In this paper, the portfolio decision-making...

In this paper, an ADaptive Immune Algorithm (ADIA) based on the artificial immune system (AIS) is proposed for the dependent task scheduling on Network on Chip (NoC). We increase the diversity of population of AIS in two ways, and improve the output result of scheduling. On one hand, new calculation...

PHM (Prognostic and Health Management) which is proposed by American army in JSF plan has gone through the fault diagnosis, fault prognostic and system integration three phases, and develops fast in both electronic and mechanical field. In this paper, the technical superiority of PHM is analyzed, and...

As the development of human genomic project, the life science research has entered the post-genome era. The study of the function of the encoded proteins is one of the hotspots in life-science research and protein subcellular localization is an important basis for functional study of the protein. The...

It is a tough task to discover semantics implied by low-level image data. In view of this situation, single concept clustering (SCC), a new algorithm for semantic partitioning of data set according to a single concept is presented. First, data is preprocessed and an uniform interface obtained for the...

Data dependencies theory is the basic tool for analyzing and designing of relational database. How to Judge whether two sets of functional dependencies are equivalent This is a basic and important problem solved by using Armstrong’s axioms in data dependencies theory. In this paper we shall point out...

Let p be a primes with p1(mod 6). In this paper,we calculate the linear complexity of the connection polynomial of a balanced binary Hall's sextic sequence. It shows that the sequence has large linear complexity and balanced properties.

In 2011, Wang et al. presented a efficient anonymous authentication scheme with high level security. In this article, we point out that their scheme suffers to server spoofing attack and fails to preserve user’s privacy, besides the process of their proposal is incorrect. Therefore, an improved scheme...

The paper introduces a new method of feature selection through the function model of game fusion. We use the traditional three steps of accomplishing feature selection by the fusion model: Firstly, fusion model can preprocess the input information, classify the information into conflict data, redundant...

With the rapid development of colleges and universities in China, earth-shaking changes have taken place in both the quality and quantity of their national assets and the original asset management modalities have been lagging behind the pace of development. Therefore, how to effectively safeguard the...

As an important part of the next generation network, Internet of things is affecting every aspect of our lives. Now an accepted the conclusion is that M2M technology is the specific form of concrete implementation of Internet of things in current conditions. In order to realize the machine to machine...

A method of generating infrared multispectral simulation images by 3D scene is presented. The infrared images at any observation angle of the scene and a data cube of simulation images of specific waveband could be generated by the method. Some experiments have been done in waveband 3~5 m to generate...

In order to achieve the best destruction effect, the signal processing circuit of six quadrant laser detector will do the target identification and target discrimination according to the echo signal of each quadrant when the missile meets the target. In this way will make sure that the missile explodes...

For the selection a safe area during landing on asteroid, this article proposes an algorithm of selecting safe landing area based on binaryzation combined with morphology. First, it provides a new binary algorithm for highlighting the shadow area and the lighting area. Second, in order to dilate the...

One key factor of successful software project is to control software development cycle, reduce labor cost, improve software quality. Agile software development method was widely used in practice, the efficiency of software development was also increased in fact. However, for the bad control on development...
