FLEXOR: A support tool for efficient and seamless experiment data processing to evaluate musculo-articular stiffness

Background and objectiveThe evaluation of musculo-articular stiffness (MAS) is an increasingly demanded procedure with applications in different fields, such as sports performance and lower limbs injury prevention. However, this task is non-automated, time-consuming and error-prone due to manual handling of data streams and files across several software applications. Despite the fact that process automation of validated procedures helps to prevent errors, there is still a lack of easy-to-use tools for analysis, management and visualization of MAS trials. MethodsIn the present work a tool called FLEXOR has been developed which applies mathematical methods and novel algorithms to automatically adjust curves of data streams for MAS analysis decreasing substantially time employed and errors. This tool permits to define different adjustment parameters, detect curve peaks and valleys, and display the results on the fly. FLEXOR has been implemented through a component-based software development (CBSD) process. All physiological fundamentals for the biomechanical measurement have been included in the tool developed. To describe the integration of all required components a 4 + 1 view model architecture has been used. The installation guide, the FLEXOR software and some data samples can be found on its GitHub repository (https://github.com/FlexorSoftware/flexor). ResultsA multiplatform software tool to simplify traditional complex and manual procedures for MAS analysis is obtained. The tool turns them into a simple all-in-one procedure, reducing processing times from hours to a few minutes. The methodology was tested on multiple datasets generated by previous tools in former procedures as well as on real-time trials in the laboratory, showing identical results. ConclusionThe results show that the developed tool can accomplish an unfilled essential task in the analysis, management and visualization of MAS measurement. The presented software tool empowers analysts to handle the different studies, investigate different parameters related to each experiment and even test with different output parameters in each experiment, enabling real-time trials and shared studies between different analysts.

Innovative methods to make the component-based software development process more effective to produce quality software

Component-Based Software Engineering (CBSE) is a new technology used by the developers to decrease the percentage of software crisis or a procedure use to design and construction of component-based systems with the help of reusable software components according to the customer requirements. Researchers propose a CBSE process and to make this process more efficient and good in terms of quality, cost, time and risk. This study applied some methods on the development of Component-Based Software (CBS), which would be very helpful to provide the more optimal software components through CBSE. So the developer can easily develop good quality software, through which any software development organisation can produce quality component-based software’s and to make it possible this study are discussing some methods, and quality model here. This paper presents a modified optimal process to select a subset of components for specific application domain or optimal components with some good software quality model and methods with modification to increase the software quality, which fulfil the requirements of the stakeholders.

Model Driven Engineering for Crop Monitoring Applications

Along with the boom of Mobile services and the thriving Model Driven Architecture (MDA), we must consider the growing significance and utility of modeling in the development of software and solutions. The main advantages of MDA are the ability to transform one PIM into several PSMs, one for each platform or technology in which the final system will be deployed, and the automatic code generation that implements the system for those platforms from the corresponding PSMs. Service-oriented architectures (SOA) are also touted as the key to business agility, especially when combined with a model-driven approach. Model-Driven Architecture (MDA) is a well-developed concept that fits well with SOA, but until now it has been a specialized technique that is beyond practical application scope of most enterprises. Model driven and Domain engineering is the foundation for emerging “product line” software development approaches and affects the maintainability, understandability, usability, and reusability characteristics of family of similar systems. However, the existing domain engineering methods do not elicit information necessary for the Component-based Software Development process, such as, selecting and configuring appropriate components. In this paper, we suggest a method that systematically defines, analyzes and designs a crop monitoring frameworks domain to enhance reusability effectively in Model Driven Engineering and Component-based Software Development. For this, we extract information objectively that can be reused in a crop monitoring domain from the requirement analysis phase. We sustain and refine crop monitoring information, and match them to artifacts of each phase in domain engineering. Through this method, reusable domain components and malleable domain architecture can be produced. In addition, we show the practical applicability and features of our approach via a new clouding and IOT technology.

AWARENESS OF EMBEDDING SECURITY FEATURES INTO COMPONENT-BASED SOFTWARE DEVELOPMENT MODEL: A SURVEY

Current applications and systems contain the software components as the basic elements and Component Based Software Development (CBSD) has been successful in building applications and systems. However, the security of CBSD for the software component is still lacking. This study highlights the results of a survey pertaining to the embedding of security features in the CBSD process. The main objective of this survey is to investigate the awareness of embedding security features in the CBSD process in the Malaysian context. For this purpose, experts from industry as well as from the academic community were interviewed. Moreover, an online survey was formulated and e-mailed to the experts and potential candidates. The results show that the embedding of security features in the software lifecycle is crucial because the incorporation of security activities in CBSD will minimize vulnerabilities in the software system, thus reducing system cost.

Embedding Dependability Attributes into Component-Based Software Development Using the Best Practice Method: A Guideline

Current organizational vulnerabilities mainly originate from Web applications. The security holes in Web applications have resulted in credit card theft, damaged financial resources and reputation of institutions, and compromised computers. Existing Web application systems encounter a high record of vulnerabilities that target dependability attributes. Mitigating software vulnerabilities and increasing software protection against bugs or vulnerabilities are critical to increase consumer confidence in software component products. Improved software engineering practices must also be adopted to mitigate the vulnerabilities in modern systems. Component-based software development (CBSD) is a software engineering approach. CBSD has been successfully applied in many domains. However, the CBSD capability to develop secure software applications is lacking to date. Therefore, this article proposes a guideline to overcome the lack of security trust in CBSD process. The proposed guideline embeds dependability attributes into CBSD by using the best practice method. The proposed guideline is significant for eliciting, analyzing, specifying, and composing the dependability attributes of CBSD.

DEPENDABILITY ATTRIBUTES FOR INCREASED SECURITY IN COMPONENT-BASED SOFTWARE DEVELOPMENT

Existing software applications become increasingly distributed as their continuity and lifetimes are lengthened; consequently, the users’ dependence on these applications is increased. The security of these applications has become a primary concern in their design, construction and evolution. Thus, these applications give rise to major concerns on t he capability of the current development approach t o develop secure systems. Component-Based Software Development (CBSD) is a software engineering approach. CBSD has been successfully applied in many domains. However, the CBSD capability to develop secure software applications is lacking to date. This study is an extension of the previous study on the challenges of the security features in CBSD models. Therefore, this study proposes a solution to the lack of security in CBSD models by highlighting the attributes that must be embedded into the CBSD process. A thorough analysis of exist ing studies is conducted to investigate the related software security attributes. The outcome analysis is beneficial for industries, such as software development companies, as well as for academic inst itutions. The analysis also serves as a baseline reference for companies that develop component-based software.

A quality-driven framework for the selection of software components and their composition

In the component-based software development process, the main concern of the selection activity is not only to find the component that meets the functional requirements, but finding the best one, or the best combination of components that meet these requirements by minimising costs and time to market, and producing high quality software. In this paper, we present a three-phase framework to assist developers in the selection activity. The framework allows users to specify their functional requirements in natural language and to introduce the architectural specifications as well as the quality requirements of the expected components or their composition. The framework uses a faceted characterisation model which allows exploiting both the documentation provided with components, their architectural properties, and their quality characteristics. The selection is performed using information retrieval techniques to measure the functional capacity of components, and uses a suite of metrics to evaluate components and their compositions according to their architectural properties. Finally, their quality is assessed by exploiting the analytic hierarchy process AHP method for multi-criteria decision-making.

Component-Based Method for the Modeling and Control of Modular Production Systems

Control software systems for manufacturing plants reveal common system architectural elements. This suggests taking advantage of a development paradigm based on reusable components. Creating and upgrading a repository of reusable components suitable for many systems that share common characteristics present a challenge for engineers, especially if composition mechanisms must be founded on control theories of discrete event systems and if formal synthesis tools must be integrated into well-accepted component-based software development processes. This paper explores a component model and a pragmatic method for the development of control software systems. The method, along with the underlying component model, fills the gap between a hierarchical control theory and component-based software engineering. A detailed case study developed around a Festo didactic learning modular production system demonstrates the relevance of the proposed approach to industrial application.

Improvement of component selection process using Genetic Algorithm for Component-Based Software Development

Modern information systems are becoming more expensive to build and maintain. Software development management and software quality goals are necessary, but not sufficient for the needs of today's marketplace. Shorter cycle time, completed with fewer resources is also in demand. Therefore, organisations are turning to Component-Based Software Development (CBSD). Potentially, CBSD can be used to reduce software development time by bringing the system to markets as early as possible. CBSD process consists of four major processes: component qualification, component adaptation, component composition and component update. To realise the benefits which CBS brings it is imperative that the right software component is selected for a project, because selecting inappropriate component may results in increased time and cost of software development which CBSD aims at reducing. Component selection is a major challenge to CBS developers, due to the multiplicity of similar components on the market with varying capabilities. Although several approaches and criteria have been proposed for component selection, there is no well-defined procedure to select optimised components. In this article, an automated approach is proposed based on Genetic Algorithm that enables the selection of software components both considering functional and non-functional requirements to find the best combination of components.

An affiliated search system for an electronic commerce and software component architecture

This paper describes an Electronic Commerce Goods Search System (ECGSS) that has functions that increase the precision of search results through training of the search system and uses affiliated business transaction processes. The software component architecture for ECGSS also allows the effective deployment of the system on every local business site, in view of the evolving trend in information technology toward easier configuration and re-usability. A general information gathering system with the infrastructure to accept every Internet communication protocol and access control is described. In this affiliated business transaction model, we classify Internet sites into two groups: a cooperative sites group, and a non-cooperative sites group. While designing the components, we optimized their specifications with respect to the whole architecture analysis, dependencies, and interface types using a component-based software development process. Experiments on the effectiveness of the user training function for the search system and the response time for simple queries for each communication protocol are presented. Comparisons of commercial search solutions and architectural standards of several organizations are also given.

Software component composition based on ADL and Middleware

How to compose prefabricated components is a key issue in component-based reuse. Research on Software Architecture (SA) and Component-based Software Development (CBSD) provides two hopeful solutions from different perspectives. SA provides a top-down approach to realizing component-based reuse. However, it pays insufficient attention to the refinement and implementation of the architectural descriptions, and does not provide the necessary capability to automate the transformation or composition to form a final executable application. CBSD provides a bottom-up way by using existing middleware infrastructures. However, these technologies do not take into account the systematic methodology that can guide the CBSD process, especially the component composition at higher abstract levels. We argue that it is a natural solution to combine these two approaches.

Component mining: a process and its pattern language

An important issue in a component-based software development process is the supply source of mature, reliable, adaptable and maintainable components. We define as component mining the deliberate, organised and automated process of extracting reusable components from an existing rich software base and present a pattern language used for mining components from programs that are typically executed as non-interactive autonomous processes. We describe the patterns in terms of intent, motivation, applicability, structure, participants, consequences and implementation. Based on the pattern language, we describe the implementation of a set of COM components that encapsulate the Unix filters and an exemplar application that uses them.
