Developing a component-based software requires verified and standardized software components. This paper presents a component quality management (CQM) process. The process was developed and applied to the government-sponsored trial projects that developed software components. The process is composed of four phases：quality specification, quality planning, quality control, and quality evaluation. With this process, we can establish quality goals and focus our efforts on the activities to achieve the goals. A component quality model is also suggested to transform the implicit quality requirements into the measurable quality goals and to be used for the basis when we evaluate the quality of software components against the quality goals.

The railroad geotechnical management system using ActiveX component is developed In this study. Component software is realized as a way that can offer good productivity and stability in software production through maximizing the reusability of software. Developed component software is very useful in saving to much time required for the development, increasing the re-usage rates, utilizing the component per function and substantially reducing the expenses for the tests and the error corrections. In addition, since it is easy to replace with other types of components that satisfy the needs of users, we can easily customize the applications.

Component adaptation is widely recognized as one of the main problems of the components, used in component based software engineering (CBSE). We developed methods to adjust the components classified by the keywords. Three main methods are discussed in this article those methods are combined with several domain component interfaces, high level simple notation for the adapter design patterns. The automated process for classifying high-level components are using adaptation is novel to software engineering domain. All Specifications and many technologies for re-using software, CBD and further developments have been emerged in recent years. The effects of these technologies on program quality or software costs must be analyzed. The risk concerns a single technology and must identify its combinations. In this paper, we are going to discuss the methods to adapt components of different technologies

Hybrid deployment under current cloud data centers is a combination of online and offline services, which improves the utilization of the cluster resources. However, the performance of the cluster is often affected by the online services in the hybrid deployment environment. To improve the response time of online service (e.g. search engine), an effective scheduling algorithm based on Storm is proposed. At the component level, the algorithm dispatches the component with more influence to the optimal performance node. Inside the component, a reasonable resource allocation strategy is used. By searching the compressed index first and then filtering the complete index, the execution speed of the component is improved with similar accuracy. Experiments show that our algorithm can guarantee search accuracy of 95.94%, while increasing the response speed by 68.03%.

Recently a lot of researches on the component-based software product lines and on applying generative programming into software product lines are being performed actively. This paper proposes an automatic component reconfiguration tool that could be applied in constructing the component-based software product lines. Our tool accepts the reuser's requirement via a feature model which is the main result of the domain engineering, and makes the feature configuration from this requirement. Then it generates the source code of the reconfigured component according to this feature configuration. To accomplish this process, the component family in our tool should have the architecture of GenVoca that is one of the most influential generative programming approaches. In addition, XSLT scripts provide the code templates for implementation elements which are the ingredients of the target component. Taking the ‘Bank Account' component family as our example, we showed that our component reconfiguration tool produced automatically the component source code that the reuser wants to create. The result of this paper would be applied extensively for creasing the productivity of building the software product lines.

Model-driven and component-oriented development is increasingly being used in the development of embedded systems. When combined, both paradigms provide several advantages, such as higher reuse rates, and improved system quality. Performing model-driven and component-oriented development should be accompanied by a component model and a method that prescribes how the component model is used. This article provides an overview on the MARMOT method, which consists of an abstract component model and a methodology for the development of embedded systems. The paper describes a feasibility study that demonstrates MARMOT's capability to alleviate system design, verification, implementation, and reuse. Results indicate that model-driven and component-based development following the MARMOT method outperforms Agile development for embedded systems, leads to maintainable systems, and higher than normal reuse rates.

Recently, above 50 percentages of software are being developed based on distributed application platforms. And recent technologies such as EJB(Enterprise Java Beans)[1]COM(Component Object Model)[2] CORBA(Common Object Request Broker Architecture)[3] have been advanced for distributed component-based software development . Therefore a systematic development process is necessary to develop component based applications using distributed application platforms. However, most of component-base software development processes do not define concrete flows between tasks and relationships among artifacts of each task Also, distribution issues are not considered explicitly in most of component-based software development In this paper, we present an approach to analyze and design software based on distributed components. In this approach, we propose systematic guidelines for developing a software based on Unified process and the relationships among artifacts which are produced, Also we explicitly consider the distribution issues such as performance, fault tolerance, security, distributed transaction of CORBA environments.

Software architecture is depend on software quality for in the design phase. Architecture interoperability have a effect in the software quality. As a result, the software quality will deteriorate. Therefore, we are need to check that configuration component for a flexible architecture and quality in the architecture. In this paper, we are suggest that configuration component of the architecture interaction.

In genome-wide association studies, pathway-based analysis has been widely performed to enhance interpretation of single-nucleotide polymorphism association results. We proposed a novel method of hierarchical structural component model (HisCoM) for pathway analysis of common variants (HisCoM for pathway analysis of common variants [HisCoM-PCA]) which was used to identify pathways associated with traits. HisCoM-PCA is based on principal component analysis (PCA) for dimensional reduction of single nucleotide polymorphisms in each gene, and the HisCoM for pathway analysis. In this study, we developed a HisCoM-PCA software for the hierarchical pathway analysis of common variants. HisCoM-PCA software has several features. Various principle component scores selection criteria in PCA step can be specified by users who want to summarize common variants at each gene-level by different threshold values. In addition, multiple public pathway databases and customized pathway information can be used to perform pathway analysis. We expect that HisCoM-PCA software will be useful for users to perform powerful pathway analysis.

It is common to measure multiple coverage metrics during software testing. Software reliability growth models and coverage growth functions have been applied to each coverage metric to evaluate software reliability; however, analysis results for the individual coverage metrics may conflict with each other. This paper proposes the virtual coverage metric of a normalized first principal component in order to avoid conflicting cases. The use of the virtual coverage metric causes a negligible loss of information.
