Productivity Evaluation Of Self-Adaptive Software Model Driven Architecture, Basel Magableh Sep 2011

Productivity Evaluation Of Self-Adaptive Software Model Driven Architecture, Basel Magableh

Articles

Anticipating context changes using a model-based approach requires a formal procedure for analysing and modelling context-dependent functionality and stable description of the architecture which supports dynamic decision-making and architecture evolution. This article demonstrates the capabilities of the context-oriented component-based application-model-driven architecture (COCA-MDA) to support the development of self- adaptive applications; the authors describe a state-of-the-art case study and evaluate the development effort involved in adopting the COCA-MDA in constructing the application. An intensive analysis of the applica- tion requirements simplified the process of modelling the application’s behavioural model; therefore, instead of modelling several variation models, the developers modelled an extra-functionality …


Model-Driven Productivity Evaluation For Self-Adaptive Context-Oriented Software Development, Basel Magableh, Stephen Barrett Sep 2011

Model-Driven Productivity Evaluation For Self-Adaptive Context-Oriented Software Development, Basel Magableh, Stephen Barrett

Articles

Anticipating context changes using a model-based approach requires a formal procedure for analysing and mod- elling their context-dependent functionality, and a stable descrip- tion of the architecture which supports dynamic decision-making and architecture evolution. This article demonstrates the capabil- ities of the context-oriented component-based application-model- driven architecture (COCA-MDA) to support the development of self-adaptive applications; we describe a state-of-the-art case study and evaluate the development effort involved in adopting the COCA-MDA in constructing the application.

Self-Adaptive Application For Indoor Wayfinding For Individuals With Cognitive Impairments, Basel Magableh, Stephen Barrett Sep 2011

Self-Adaptive Application For Indoor Wayfinding For Individuals With Cognitive Impairments, Basel Magableh, Stephen Barrett

Articles

This article focuses on describing a Model Driven Archi- tecture (COCA-MDA) approach that facilitates the develop- ment of self-adaptive application for indoor wayfinding for individuals with cognitive impairments. COCA-MDA pro- vides the following benefits: 1) It enables the architecture to anticipate several behavioural variations based on the context and the specific needs of the individuals with cog- nitive impairments. 2) It enables the application to proac- tively anticipate or reactively address unforeseen changes through support by a dynamic-decision making and policy framework. The policy framework is based on a stable de- scription of software models and proprieties. 3) It can …


Application Of Stochastic Diffusion For Hiding High Fidelity Encrypted Images, Jonathan Blackledge, Abdulrahman Al-Rawi Jan 2011

Application Of Stochastic Diffusion For Hiding High Fidelity Encrypted Images, Jonathan Blackledge, Abdulrahman Al-Rawi

Articles

Cryptography coupled with information hiding has received increased attention in recent years and has become a major research theme because of the importance of protecting encrypted information in any Electronic Data Interchange system in a way that is both discrete and covert. One of the essential limitations in any cryptography system is that the encrypted data provides an indication on its importance which arouses suspicion and makes it vulnerable to attack. Information hiding of Steganography provides a potential solution to this issue by making the data imperceptible, the security of the hidden information being a threat only if its existence …


Detecting The Onset Of Dementia Using Context-Oriented Architecture, Basel Magableh, Nidal Albeiruti Jan 2011

Detecting The Onset Of Dementia Using Context-Oriented Architecture, Basel Magableh, Nidal Albeiruti

Articles

In the last few years, Aspect Oriented Software De- velopment (AOSD) and Context Oriented Software Development (COSD) have become interesting alternatives for the design and construction of self-adaptive software systems. An analysis of these technologies shows them all to employ the principle of the separation of concerns, Model Driven Architecture (MDA) and Component-based Software Development (CBSD) for building high quality of software systems. In general, the ultimate goal of these technologies is to be able to reduce development costs and effort, while improving the adaptability, and dependability of software systems. COSD, has emerged as a generic devel- opment paradigm towards …
