Near Eyes-Free Chauffeur Computer Interaction with Chording and Visual Text Mnemonics
(Journal of Universal Computer Science;16 (10), Journal article; Peer reviewed, 2010)Modern cars are equipped with advanced technology requiring cognitively complex operation that is reliant on the user’s visual attention. It is therefore hazardous for drivers to operate such devices while driving. In ... -
Net Auto-Solver: A formal approach for automatic resolution of OpenFlow anomalies
(Conference on Local Computer Networks; 2020 IEEE 45th Conference on Local Computer Networks (LCN), Journal article; Peer reviewed, 2021-01-15)Policy anomalies are frequent in nowadays’s computer networks due to their increasing configuration complexity. Resolving policy anomalies usually requires network administrator intervention, which is a time-intensive and ... -
.NET/C# instrumentation for search-based software testing
(Peer reviewed; Journal article, 2023)C# is one of the most widely used programming languages. However, to the best of our knowledge, there has been no work in the literature aimed at enabling search-based software testing techniques for applications running ... -
A neural network model and framework for an automatic evaluation of image descriptions based on NCAM image accessibility guidelines
(Chapter; Peer reviewed, 2021)Millions of people who are either blind or visually impaired have difficulty understanding the content in an image. To address the problem textual image descriptions or captions are provided separately or as alternative ... -
A neuro-inspired general framework for the evolution of stochastic dynamical systems: Cellular automata, random Boolean networks and echo state networks towards criticality
(Cognitive Neurodynamics;, Journal article; Peer reviewed, 2020-06-11)Although deep learning has recently increased in popularity, it suffers from various problems including high computational complexity, energy greedy computation, and lack of scalability, to mention a few. In this paper, ... -
A new decision making model based on Rank Centrality for GDM with fuzzy preference relations
