The Unified Modelling Language (UML) is a language that helps to visualize, design and document models of software systems. It represents a collection of the best engineering practices that have proven successful in modelling large and complex systems. UML is widely used in designing large and reliable software systems required by banks and other corporate(More)
Sequential patterns mining is an important datamining technique used to identify frequently observed sequential occurrence of items across ordered transactions over time. It has been extensively studied in the literature, and there exists a diversity of algorithms. However, more complex structural patterns are often hidden behind sequences. This article(More)
We present a novel application of machine vision methods for the identification of chemical composition diagrams from two-dimensional digital raster images. The method is based on the use of Gabor wavelets and an energy function to derive feature vectors from digital images. These are used for training and classification purposes using a Kohonen network for(More)
This paper proposes a RSSI-aware (rETT) routing metric for WMN. The embedded RSSI information from the mesh nodes are extracted, processed, transformed and incorporated into the routing process. The performance of the rETT metric is then optimised and the results compared with the fundamental hop count metric and the link quality metric by Expected(More)
Biometric recognition refers to the automatic recognition of individuals based on their physiological and/or behavioral characteristics. It is used to confirm an individual's identity rather than using an identification card. Unique identifiers of humans include fingerprints, hand geometry, earlobe geometry and retina. Fingerprint verification is one(More)
A facial expression is one of the non-verbal information that plays an important role in understanding face-to-face communications. Therefore, facial expressions are the most important means of detecting emotions and behavioral analysis science. Although human being have ability recognize the face practically without any effort, but facial recognition(More)
Based on the technology acceptance model, this research proposes an extended model in the context of e-learning systems. In the proposed model, enjoyment and computer playfulness were added. A sample of 54 respondents participated in the study. The results suggest that perceived usefulness is the strongest determinant towards behavioural intention, while(More)
