A system has dynamic adaptability if it can adapt itself to dynamically changing runtime environments. As open-ended distributed systems and mobile computing systems have spread widely, the need for software with dynamic adaptability increases. We propose a model of software with dynamic adaptability and the object-oriented re-ective language LEAD++ based on the model. The basic idea is that we...

Objective measurement of non-functional requirements (NFRs) in any software is one of the most difficult activities. This is because the inherent nature of the NFRs makes their common understanding difficult. The problem is compounded by the fact that the requirements for any software are usually vague about the NFRs that the software should satisfy and how to evaluate the NFRs in the final sof...

The value of a system usually diminishes over its lifetime, but some systems depreciate more slowly than others. Diminished value is due partly to the increasing needs and wants of the system’s stakeholders and partly to its decreasing capabilities relative to emerging alternatives. Thus, systems are replaced or upgraded at substantial cost and disruption. If a system is designed to be changed ...

When executing scientific applications, resources that may be used can vary from multi-core processors to grids. Therefore, abstracting the programming model enables portability on various resource infrastructures. Furthermore, software component technology appears to be a very promising approach to deal with the growing complexity of scientific applications. Hence, we proposed a model to impro...

To achieve the adaptability required in ALS, adaptive learning system (ALS) takes advantage of granular and reusable content. The main goal of this paper is to examine the learning object granularity issue which is directly related with Learning Object (LO) reusability and the adaptability process required in ALS. For that purpose, we present the learning objects approach and the related techno...

OBJECTIVE Fostering career adaptability may improve vocational outcomes for adolescents. This study examined the responses of adolescents on the Adolescent Role Assessment (ARA) to explore its usefulness as a measure of career adaptability. METHOD The ARA was administered to 101 adolescents 12 to 17 years of age. Descriptive statistics, reliability analysis, and factor analysis were generated...

Adaptable networking means that the provided networkbased services are capable of handling dynamic changes in both time and position related to resources, users and changed service requirements. This paper is discussing several aspects of adaptability. Adaptability implies flexibility, and comprises features related to various aspects of the functionality of a network-based service system such ...

CI architectures are characterized by personnel, resources and tasks and the set of relationships linking them. This is the PCANSS formalism. A set of units – simulated and real – are represented in this way and a series of design metrics measured. Performance and adaptability measures are also captured. The data is then analyzed to examine whether there is a tradeoff between performance and ad...
