We present a fuzzy logic based methodology of decision making on bandwidth allocation in a substrate network with DaVinci architecture, according to which the physical substrate network is divided into virtual networks. This methodology describes a fuzzy modification of the adaptive bandwidth allocation mechanism introduced in order to optimize decision making under uncertain network conditions by...
Global development has shifted through three phases: the industrial age, the information age and now, it is in the age of rapid technology. In this 21st Century context, Asian nations need to innovate, and the key to doing so lies in nurturing their young learners through the shift to an Innovation-based model of learning. Introduced and explained through its two components, a mode of autonomy and...
A Context-Aware Usage CONtrol (CA-UCON) model is an extension of the traditional UCON model which enables adaptation to environmental changes in the aim of preserving continuity of usage in a pervasive computing system. When the authorisations and obligations requirements are met by the subject and the object, and the conditions requirements fail due to changes in the environment or the system context,...
In recent years research on the integration of BPM and social software has tried to overcome the limitations of the traditional BPM approaches. The potential of Social BPM (SBPM) and social software towards the enhancement and advancement of the traditional BPM lifecycle have been argued. This paper aims to address gaps in social BPM research by working towards a goal-driven SBPM meta-model that seamlessly...
This paper reports on the development of a model to improve the understanding of the extent of Enterprise Resource Planning (ERP) system usage in universities. Previous research revealed that university ERP systems are not fully utilized by end-users, resulting in low usage and institutional inefficiencies. This leads to stakeholders particularly students and government pressurizing universities to...
Use Case diagrams are widely used to model system behaviour and also to represent user's interaction with the system. Context Aware Systems (CASs) are dynamic in nature and their response is based on varying parameters such as time and location. Due to this dynamic nature, such systems cannot be represented by the existing form of use case diagrams. In this paper the authors present a set of enhancements...
This paper presents a tool and a framework to develop accessible and adaptable digital TV interfaces for disabled and elderly users. The development methodology involves disabled and elderly users early in the design process and optimizes interfaces using a simulation system. The simulator complements existing user centred design processes and helps designers to understand, visualize and measure effect...
