A deliberative model for self-adaptation middleware using architectural dependency

A crucial prerequisite to externalized adaptation is an understanding of how components are interconnected, or more particularly how and why they depend on one another. Such dependencies can be used to provide an architectural model, which provides a reference point for externalized adaptation. In this paper, it is described how dependencies are used as a basis to systems' self-understanding and subsequent architectural reconfigurations. The approach is based on the combination of: instrumentation services, a dependency meta-model and a system controller. In particular, the latter uses self-healing repair rules (or conflict resolution strategies), based on extensible beliefs, desires and intention (EBDI) model, to reflect reconfiguration changes back to a target application under examination

Critical Analysis and Evaluation of the UAE Twelfth Grade Students’ Language Instructional Material Based on the Set Goals and Objectives

Textbook is in the heart of any language teaching and learning program as it relieves some pressure placed on teachers’ shoulders, provides students with a sense of progress and cohesion as well as providing education systems with the main structure by which they work and function. Therefore, great attention is paid to this critical area of research by syllabi developers and designers in addition to educationalists, scholars and researchers as a way to improve second language teaching and learning. One of main areas that concerns with the development of textbooks is to evaluate such textbooks to meet students’ needs in accordance with the intended goals and objectives. The current research focuses on evaluating the UAE twelfth grade students’ language textbook to check its compatibility, in terms of layout, topic and design, with the goals and objectives as set by the UAE educational process’s decision makers. Some recommendations for the effective use of the current instructional material as well as some suggestions for future research are provided

Evaluating the Significance of the UAE 12th Grade Language Instructional Material in Motivating Students to Achieve the Intended Goals Based on the Content-Based Approach

This paper evaluates the current UAE 12th grade language material in terms of its compatibility with the adopted approach and suitability for students’ educational and cognitive levels in order to ascertain whether the present material motivates students to learn or not. The results of the current studies show that the current material is well-designed using the content-based approach to enhance students’ learning of the four basic language skills, highlighting some benefits to sustain and some drawbacks to improve, along with some useful recommendations for future research. Keywords: content-based approach, theme-based model, CALP, BICS

Self-managed cells and their federation

Future e-Health systems will consist of low-power, on-body wireless sensors attached to mobile users that interact with a ubiquitous computing environment. This kind of system needs to be able to configure itself with little or no user input; more importantly, it is required to adapt autonomously to changes such as user movement, device failure, the addition or loss of services, and proximity to other such systems. This extended abstract describes the basic architecture of a Self-Managed Cell (SMC) to address these requirements, and discusses various forms of federation between/among SMCs. This structure is motivated by a typical e-Health scenario
