Change management or configuration management is becoming necessity for every facet of software system development. Traceability of objects i.e. artifacts or information units becomes core talent for authentic determination of the parametric information over the explicit instance of time. This paper presents the evolving and useful concept of traceability management wrapped in change management paradigm...
The coal mine detect and rescue robot is used for detecting the explosion environment of coal mine and rescuing miners who are trapped in the underground coal mine after gas explosion. Coal mine is a dangerous place in which many fatal factors menace miners' life, especially when blasts occurred. Rescue crews usually don't know the actual situation of the mine tunnel under such circumstances. Therefore...

The formulation and sustenance of an IT risk management framework is one of the critical and challenging tasks of modern corporate enterprise risk management. The existence of a risk assessment tool allows for effective...
Poisson-Nernst-Planck (hereinafter referred to as PNP) is applied to describe ion transport in clay microscale structure and obtain the macroscopic PNP multi-ions transport model in clay through volume averaging. Use numerical analysis to research microscale quantities such as ion background concentration and particle surface charge density as well as the influence of clay microscale structure on...
Here introduces a monitor system technically based on ARM7 embedded micro processor (HMS30C7202) and Micro C/OS-II embedded operating system. The paper provides the scheme of the principal, introduces the connection method of outside signals, tells about how to transplant the Micro C/OS-II to the operating system, and shows the programming emphases and some source code of the majority of the program.
Utilizing direct sequencing technique, a consensus nucleotide sequence of pig MyoG gene was got from 63 individuals in this experiment. At the same time, the MyoG gene sequences of 11 different species were collected from Genbank. The coding sequence and deduced amino acid sequences of these species were compared to study the genetic diversity and phylogeny of MyoG gene between pig and other species...
The ever increasing diversification of Web services and software applications poses a real challenge to developers and designers when creating software that has to cope with a myriad of interaction situations, as well as specific directives for ensuring an accessible interaction. Utilizing an advanced web services accessibility assessment tool, they can obtain a better understanding of the accessibility...
In a video game, it is common to embed a prerecorded video and play it at various times during the game for the purposes of narrative, tutorials, hints, or any other goal that the developer sees fit in the game. It is a challenging task to play the embedded video in a cross-platform video game at multiple locations of the screen simultaneously and on an arbitrary surface. This paper describes the...
Online payment is the key point and the basic conditions to the development of electronic commerce, which greatly promote the development of e-commerce, and brought prosperity to the e-commerce. As e-commerce is one of the fastest economic growth of China, the online payment and its security becomes particularly important. This paper analysis from three aspects: the current development status of e-commerce...
In this paper, based on the research of the existing heterogeneous database integration systems, according to the data exchange and sharing needs of enterprise heterogeneous databases, a framework for heterogeneous database integration system is proposed and designed, and the key technologies of the system implementation process are also described in detail. The system provides a heterogeneous data...
Facing changing environments and evolving business, service composition happens all time. However, services do not always interact properly because of mismatches between their interfaces. In this paper, we use labelled interface automata, an extension of interface automata, to illustrate mismatching interfaces and resolution approaches. We model service interfaces with labelled interface automata...
Through the research of current digital signal processing, this paper presents a design with FPGA to achieve FFT, gives the overall implementation framework, and focuses on the design and implementation of the FFT algorithm processing unit, thereby increasing the operation speed of the digital signal processor and reducing the computational complexity.
To follow the technology advancement and satisfy the needs on the RTI software in the “Cloud computing” age, a scheme of remodeling the traditional RTI software to be with “Platform as a Service (PaaS)” architecture was proposed. Software construction, sub-component functions and the method of interacting based on the remodeled RTI software on the WAN were studied. The focus was scheduling computing...
Compared with traditional component-based software, service-oriented software has the characteristics of loose coupling, delayed binding, etc. According to the characteristics of SOA, this paper analyzes the factors affecting software maintainability, presents an evaluation method of service-oriented software maintainability. We divide the maintainability of software for analyzability, changeability,...
Energy is one of the most important metric when we talk about Mobile ad-hoc networks. In order to increase the system's life-time, energy consumption has to be minimized. Here we will look at some energy saving algorithms. The initial analysis tells us that LECA conserves more energy that SPAN or any other algorithm. We present a Localized Energy Conservation Algorithm (LECA) [3] for routing in Mobile...
Through the analysis of the existing educational technology management status, combining with the existing project management knowledge systems and educational technology management knowledge, this paper proposes a management program based on educational technology and realizes it. This program is a common program to solve such problems and therefore has a high versatility and practical value.
Time synchronization is extremely important for wireless sensor networks. Since the sensors have very limited energy resources and it is very difficult to change batteries for the sensor nodes, energy efficiency is one of primary importance for a sensor network. To prolong the lifetime of a sensor network, we proposed a cluster based on demand time synchronization in wireless sensor networks(COD)...
Particle swarm optimization (PSO) is an optimization algorithm that has received much attention in recent years. PSO is a simple and computationally inexpensive algorithm inspired by social behavior of bird flocks and fish schools. However, PSO suffers from premature convergence, especially in high dimensional multimodal functions. To improve PSO performance on global optimization problems, this paper...
With the rapid development of the network technology and education technology, network education is developing quickly. The development of network education promotes the research and development of a variety of software and systems supporting network education. But most of the existing network education supporting systems lack of personalized learning environment and are less intelligent, which can...
There are many factors, such as temperature, humidity, concentration of oxygen and carbon dioxide, influencing freshness of garden stuff. An intelligent monitoring system was designed to ensure the quality of it. In order to balance the environmental deviation between different areas, the system used multi-channel sensors to cycled check environment. Without effecting control accuracy, the system...
