The modelling and designing of E-Supervised (E-SUV) for distance learning centre

E-services is a suite of web-based products brings profound changes in business models and value chains especially for Professional and Continuing Education Centre (PACE) environment due to its responsibility to manage all courses provided by every faculty to private colleges.PACE is currently running resourcefully but it is facing a few problems such as the difficulties of each faculty officer to get information about private colleges, and a lack of information management in private colleges itself.Therefore, the objective of this study is to propose a model of e-service application called E-Supervised (E-SUV) to provide the information related to twinning programmes between Universiti Utara Malaysia (UUM) and private colleges by enabling users to interact via portal by using the UML-based Web Engineering (UWE) approach.This methodology includes four modeling activities which are requirement analysis, conceptual model, navigation model and presentation model. This research results in a web-based environment consisting of major modules such as profiles, forums, and email service for users to utilize.In a nutshell, UWE approach is a viable option to facilitate e-services in education environment and thus could serve as a guideline model of future edistance learning centre.Rigorous tests to see how this model behaves under real-life practice would be a way forward to identifying its effectiveness

Taguchi and BEM Analyses on the Productivity Performance of an Oil Reservoir

The application of Taguchi Robust Design Technique (TRDT) coupled with the Boundary Element Menthod (BEM) in analyzing the productivity performance of an oil reservoir is presented in this paper. Several reservoir rock and reservoir fluid properties; i.e. permeability, thickness, porosity and viscosity, were choosen in this study. The BEM allows the overall simulation of reservoir performance to be made; whereas the used of TRDT allows us to rank the most influencing factor (property) that affects the productivity performance of the reservoir. Numerical values obtained from the BEM analysis will be used as input data for the TRDT statistical analysis. Result indicated that oil viscosity is the most important factor that affects the productivity performance of the oil reservoir followed by the thickness of the pay zone, the rock permeability and the rock porosity. Results of this study can be used by reservoir engineer in making the right choice of Enhance Oil Recovery techniques that is the most suitable for the reservoir

The modeling of E-Supervised (E-SUV) for distance learning centre

E-services is a suite of Web-based products that will allow any business or service running globally and efficiently. It brings profound changes in business models and value chains especially for Professional and Continuing Education Centre (PACE) environment due to its responsibility to manage all the courses provided by every faculty to private colleges.Even though PACE is running resourcefully but it is still facing a few problems such as the difficulties of each faculty officer to get information about private colleges, inability communication between PACE and private colleges directly and, a lack of information management in private colleges.Therefore, this study tries to propose a model of e-service application called E-Supervised (E-SUV) to provide the information related to twinning programs between Universiti Utara Malaysia (UUM) and private colleges.It enables users to interact via portal by using the UML-based Web Engineering (UWE) approach

Mechanical and thermal characterization of resin-infused cotton fabric/epoxy composites: influence of woven construction parameters and surface treatments.

This study explores the mechanical and thermal characterization of epoxy-based composites reinforced with chemically modified woven cotton fabrics using the resin infusion technique. The woven fabrics construction parameters were varied in terms of weft yarn counts (16, 20, and 24 Tex) and pick densities as defined by pick wheel teeth (PWT) (30, 36, and 41 T). The fabrics were surface treated with 6% concentration of sodium hydroxide (NaOH) using the alkali treatment method. The obtained results revealed that mechanical strength improved with decreasing weft yarn count and increasing PWT. Notably, chemically treated composites with the highest PWT exhibited superior strength compared to untreated counterparts, attributed to more compact microstructures, reduced fabric/fiber breakages, and enhanced interfacial bonding between the reinforced plain-woven cotton fabric and epoxy matrix. Thermogravimetric analysis (TGA) showed that all composites have higher thermal stability above 300°C, with untreated fabric composites exhibiting the highest resistance to degradation, whereas the treated composite quickly degraded at an onset temperature of 288.4°C due to the removal of the hemicellulose, decomposition of the cellulose, and lignin content. In conclusion, the study indicates that surface treatment and woven construction parameters such as weft yarn counts and pick wheel teeth, as well as the resin infusion technique, significantly influence the mechanical, microstructural, and thermal properties of resin-infused woven cotton reinforced composites for potential application in industrial and automotive sectors, offering lightweight, durable solutions for components such as construction and building panels, doors, and roof panels

A study on motorcyclist's riding discomfort in Malaysia

Studies on discomfort among motorcyclists are seldom seen in literature. The current study was carried out using 957 respondents representing 481 males and 476 females ranging from the age of 18 to 24 years. It attempts to find out the overall discomfort score, the discomfort symptom score and the statistically significant differences on discomfort score among the male and female motorcyclists. A questionnaire survey was used to evaluate those discomfort symptoms. The results indicate that a majority of the male and female motorcyclists experienced discomfort in their body parts during the riding process. The motorcyclists mainly experienced discomfort on their upper body parts (neck or head, shoulder, upper back, arms and hands, low back and buttocks). The female compared to the male motorcyclists have expressed higher discomfort level in their thighs. Meanwhile a majority of both male and female motorcyclists have indicated no discomfort in their lower body parts (knees, calf leg below knee and ankles and feet). Meanwhile, the statistical tests indicate that there is a total of four significant differences (p<0.05) between the male and female motorcyclists. The significant differences were on low back, buttocks, thighs and calf leg below knees. As a conclusion, the results suggest that the motorcyclists in Malaysia do suffer from the discomfort on certain body part during riding. Therefore, this study highlights that there is a lack of motorcycle’s ergonomics particularly in the context of interaction between the riders and motorcycle in Malaysia
