Abstract- Software quality is a complex issue in any applications. The purpose of an education web-based application in higher learning institution is to provide online facilities or services to academicians. The study attempts to identify quality attributes of web-based integrated Student Assessment Application (iCGPA) among academicians. Online survey questionnaires were distributed among academicians from Malaysian public institutions for pilot study. Rasch Measurement Model is used to identify the items needed for a web-based iCGPA system. Rasch Unidimensional Measurement Model software known as WiNSTEPS is used to assess and analyse respondent responses. The items were analysed for person-item map and misfit data. Each analysis is discussed in depth based on item and person. Results shows that the quality items proposed is agreed based on the responses retrieved. Finally, inputs from pilot study will be used to improve actual study.

Keywords- Software Quality Model, Quality Model, Web-based Quality Model, Rasch Measurement Model, Rasch Analysis, Software and Educational Application

Abstract- An increase in energy consumption of home appliances is a growing problem in distribution system. The Demand Response (DR) strategy for reducing the energy usage is the key for any energy management system (EMS). In order to minimize the electricity consumption in domestic sector, the smart energy controller (SEC) with Internet of Things (IoT) is essential. In this paper, the smart energy controller is proposed for residential air conditioner (RAC) to save the electricity and electricity’ cost using new algorithm based on DR. Hardware prototype of SEC and software is designed to demonstrate the proposed the energy management system (EMS) for control the thermostat of RAC. The proposed DR algorithm is applied under three strategies in which the first strategy considers operation at one day of week from 12 pm to 12 am and the second strategy considers controlling of thermostat by sensing inside room temperature during 12 pm to 12 am of the day and third strategy considers operation of RAC by real time price (RTP) with several cases. The Experimental results of the proposed SEC are compared with each other strategy of EMS. The third strategy provides better results in terms of energy consumption and electricity cost.

Abstract- The study was conducted with an objective of assessing the level of DAs’ work motivation and factors which have possible relation to, and effects upon it. The statistical population for this study was comprised of 120 DAs engaged in delivery of extension services. Given the diminutive population size, a decision was made to administer the survey to the entire population. The research was conducted based on both primary and secondary data. Primary data were collected through discussions, interview and a questionnaire survey where as secondary data were also gathered from office manuals and files to provide additional information. In accordance with the research objectives, and data characteristic, the study used descriptive and inferential statistics to analysis data. The study found that more than half (53%) of the DAs had a low level of work motivation, 26% of them had a medium level of motivation and 20% had a high level of motivation to work. The result also showed that out of the 15 factors included in analysis, 10 of them were found statistically significant and related to work motivation of DAs at different levels. The factors such as work itself, quality of supervision, recognition, promotion, and perception about salary, were positively and significantly related with job motivation at less than 1% level. While work place distance and unrealistic work load were negatively correlated at less than 1% level. Work condition and feeling of being involved also showed a positive and significant relationship with the dependent variable at less than 5% level. Therefore, it was recommended that both the higher policy makers and the management of office of agricultural and natural resources in the study area should focus on the extracted significant factors for better development agents’ motivation strategy. Nonetheless as work motivation influences by different factors and subject to change overtime, administrators should periodically assess the factors of motivation and plan accordingly.

Abstract- Thestudyofdifferenceequationshasavasthistory especially in relation to Sturm-Lioville equations and their discrete counterparts, Jacobi matrices, which have been analyzed usingsimilarandrelatedmethods.Howevermuchisneededtobe done in terms of spectral theory in the discrete setting. Therefore, in this study, we approximate the eigenvalues and establish the dichotomy condition of a Fourth Order Difference equation with Unbounded Coefficients on a Hilbert Space.
