An Adaptive Learning Ontological Framework Based on Learning Styles and Teaching Strategies
Nafea, Shaimaa; Siewe, Francois; He, Ying (Conference)Ontology are increasingly being used in a variety of applications, and particularly in adaptive e-learning. They have the potential to enable developers to create adaptive course content for specified domains. E-learning ... -
Advances in CAD simulation of textile yarns
Grishanov, S. A.; Siewe, Francois; Cassidy, T. (Article)A project aimed at the 3D simulation of textile yarns from technical specifications was begun in 1993 and attracted support from both industry and research councils to enable the formation of a multi-national team of ... -
Agent-based Negotiation Approach for Feature Interactions in Smart Home Systems using Calculus of the Context-aware Ambient
Alfakeeh, Ahmed S.; Al-Bayatti, Ali H.; Siewe, Francois; Baker, Thar (Article)Smart Home Systems (SHSs) provide several services which are tailored to different residents’ preferences. As a result, SHSs are highly exposed to undesirable interactions, known as feature interactions (FIs). FIs might ... -
Analysing Petri Nets in a Calculus of Context-aware Ambients
Siewe, Francois; Germanos, Vasileios; Zeng, W. (Conference)This paper proposes an approach to analysing and verifying Petri nets using a Calculus of Context-aware Ambients (CCA). We propose an algorithm that transforms a Petri net into a CCA process. This demonstrates that any ... -
Analysing Use Case Diagrams in a Calculus of Context-aware Ambients
Use case diagrams are an excellent tool for capturing and analyzing the functional requirements of a system under development. Context-aware use case diagrams are an extension of use case diagrams to cater for both the ... -
An application of queuing theory to modelling of melange yarns. Part I: A queuing model of melange yarn structure.
Siewe, Francois; Grishanov, S. A.; Cassidy, T.; Banyard, Geoffrey (Article)A queuing model of staple fiber yarn is presented that enables the modeling and a better understanding of fiber migration in a yarn. The model provides a fine yarn structure where the migrational behavior of fibers is ... -
An application of queuing theory to modelling of melange yarns. Part II: A method of estimating the fibre migration probabilities and a yarn structure simulation algorithm.
Grishanov, Sergei; Siewe, Francois; Cassidy, T. (Article)A queuing model of staple yarn structure was presented in Part I of this work, where the migration behaviours of fibres were simulated by the movement of customers in a Markovian network of queuing systems. Part II of the ... -
Building CPU stubs to optimize CPU bound systems: An application of dynamic performance stubs.
Trapp, Peter; Meyer, Markus; Facchi, Christian; Janicke, Helge; Siewe, Francois (Article)Dynamic performance stubs provide a framework for the simulation of the performance behavior of software modules and functions. Hence, they can be used as an exten- sion to software performance engineering methodologies. ... -
Building semantic relationships incrementally in dataspace.
Kuicheu, Nathalie Cindy; Wang, N.; Fanzou, N. T. G.; Xu, De; Siewe, Francois (Conference)Recently, the notion of Dataspace has been introduced as a virtual space where many data sources are managed regardless of their structures and locations; this, with the aim to return best efforts answers to user's queries. ... -
CA-UCON: A Context-Aware Usage Control Model
Al-Mutairi, A.; Siewe, Francois (Conference)Usage CONtrol (UCON) model is the latest major enhance- ment of the traditional access control models which enables mutability of subject and object attributes, and continuity of control on usage of resources. In UCON, ... -
The Calculus of context-aware ambients.
Siewe, Francois; Zedan, Hussein; Cau, A. (Antonio) (Article)We present the Calculus of Context-aware Ambients (CCA in short) for the modelling and verification of mobile systems that are context-aware. This process calculus is built upon the calculus of mobile ambients and introduces ... -
A case study of image retrieval on lung cancer chest x-ray pictures.
Gile Narcisse Fanzou, T.; Ning, W.; Cindy, N.; Siewe, Francois; Xudong, L.; De, X. (Conference)This paper presents a case study of an image retrieval system based on a notion of similarity between images in a multimedia database and where a user request can be an image file or a keyword. The CBIR (Content Based Image ... -
CCA: a calculus of context-aware ambients.
Siewe, Francois; Cau, A. (Antonio); Zedan, Hussein (Conference)We present a process calculus, CCA, for the modelling and verification of mobile systems that are context-aware. This process calculus is built upon the calculus of mobile ambients and introduces new constructs to enable ... -
A Comparison Study between RCCAR and Conventional Prediction Techniques for Resolving Context Conflicts in Pervasive Context-Aware Systems
In Pervasive computing environment, context-aware systems face many challenges to keep high quality performance. One-challenge faces context-aware systems is conflicted values come from different sensors because of different ...
