Predicting Software Reliability and Defects Using Bayesian Networks (Published)

This paper reviews the use of Bayesian networks (BNs) in predicting software reliability and software defects. The approach allows analysts to incorporate causal process factors as well as combine qualitative and quantitative measures, hence overcoming some of the well-known limitations of traditional software metrics methods. The approach has been used and reported on by organizations such as Motorola, Siemens, and Philips. However, one of the impediments to more widespread use of BNs for this type of application was that, traditionally, BN tools and algorithms suffered from an obvious ‘Achilles’ heel’ – they were not able to handle continuous nodes properly, if at all. This forced modelers to have to predefine discretization intervals in advance and resulted in inaccurate predictions where the range, for example, of defect counts was large. Fortunately, recent advances in BN algorithms now make it possible to perform inference in BNs with continuous nodes, without the need to pre-specify discretization levels. Using such ‘dynamic discretization’ algorithms results in significantly improved accuracy for reliability and defects prediction type models.

Computer Aided Design of Garri Frying Machine (Published)

This research is a compilation of a report on the development of a compact software for the design of an efficient and effective garri frying machine. The authors here made use of a simple and common computer ‘If’ statement. A total of fundamental forty-eight variables were interacted with. A clear and direct flow charge was presented for the running of the programme. The users interface was printed and displayed as presented in the write-up. The summary of the results were tabulated. The algorithms used were basically fundamental and could be reformed, redesigned, manipulated, multiplied and modified before the final manufacturing.

Design and Development of Software Package for the Evaluation of Water Vapour Concentration (Published)

A computer software package was designed and developed to evaluate water vapor concentration in the lower atmosphere using Visual basic programming. The package was developed for Garcia Muller model. The water vapor concentration absorbs long wave terrestrial’s radiation and insulating energy transfer through the atmosphere. The performance of the package was excellent when used to evaluate upper air data for Lagos station (Lat 60 32’ E, Longitude 30. 28’ E), Kano station (Lat 120 00N, long 80 31’E), Minana station (Lat 90 39’ N, Long 60, 32’ E) and Maiduguri station (Lat 110 53’ N, Long 130 16’ E). The size of the package is 1.08KB. The results obtained were compared with results gotten from other location and was found to be in agreement. This package will save researchers much time since it can evalvate as many data.

Analysing Qualitative Data Using Facial Expressions in an Educational Scenario (Published)

In communication, both verbal and non-verbal means ensure that a message is conveyed, and facial expressions are acknowledged as one of the most influential factors in non-verbal communication. Facial Analysis Coding System (FACS) is a tool to analyse data other than the spoken language to improve a researcher’s reading of an interviewee’s emotions, and proposes a methodology to support the annotation process of facial expressions in a piece of communication. This study investigates an applied framework for FACS in an educational scenario. The study combines both the computerised and manual entries in the applied method. The study addresses the challenges, findings and recommendations of this applied method.
