Immense increase in digital images demands an effective image retrieval system. In text based image retrieval systems, textual keywords are used for indexing. The query keywords are matched with the keywords associated with images to perform image retrieval task. Users usually demand higher proportion of the query keywords in the retrieved images than the other undesired keywords. Existing image retrieval systems retrieve images that do not contain the query keywords either in equal or higher pr...

Abstract With the ever increasing cases of cyber data breaches, the manual process of sifting through tons of security logs to investigate cyber-attacks is error-prone and time-consuming. Signature-based deep search solutions only give accurate results if the threat artifacts are precisely provided. With the burgeoning variety of sophisticated cyber threats having common attack patterns and utilizing the same attack tools, a timely investigation is nearly impossible. There is a need to automate ...

ABSTRACTDuring early childhood, children start developing their cognitive, social, emotional, and behavioural skills, laying the foundation for life-long learning. Cognitive skills are usually taught in traditional classrooms through the use of textbooks and worksheets. The learning content in these textbooks and worksheets is static pre-authored content that is repeatedly used for teaching and learning. This repetition jeopardises the child's learning of individualised and cognitive skills. Pre...

Gene Regulatory Networks (GRNs) are reconstructed from the microarray gene expression data through diversified computational approaches. This process ensues in symmetric and diagonal interaction of gene pairs that cannot be modelled as direct activation, inhibition, and self-regulatory interactions. The values of gene co-expressions could help in identifying co-regulations among them. The proposed approach aims at computing the differences in variances of co-expressed genes rather than computing...

One form of educational inequality is the disparity that exists between urban and rural settings. Equal distribution of quality education is a challenge for developing countries due to the unavailability of resources. Various approaches to equal distribution are distance learning, telecast learning and e‐learning; however, these approaches cannot achieve the desired objectives due to their limitations. This research aimed to investigate the interesting question of whether mobile technology can b...
