Internet technology is vital in education as it is an enabler tool used by students for information exchange, communication and creation of knowledge. However, issues related to Internet use behaviour (IUB) and effects on students' performance are still being debated due to inconsistent results. Thus, the main aim of this paper is to propose a specific IUB classification model to discover comprehensive...
The most conspicuous element of Gorham’s disease is its radiographic features, wherein massive disappearance of the mandible is observed. We report a case of an adolescent boy with massive osteolysis of the mandible in whom the diagnosis of Gorham’s disease was made. A 14-year-old boy was referred to the Department of Oral and Maxillofacial Surgery, Universiti Kebangsaan Malaysia Medical Centre, Kuala...
This paper presents the performance effect of hollow pyramidal microwave absorber that had been applied with slotted array principle. The Sierpinski triangle was used as the slotted on the hollow pyramidal microwave absorber. This paper includes the theories, simulation and measurement result. The simulation using CST Microwave Studio Suite used to predict the Sierpinski triangle design of microwave...
SILVACO TCAD simulator which is consisting of a process simulator, ATHENA and device simulator, ATLAS were used to simulate and analyze the electrical characterization of 45nm NMOS with strained silicon on insulator (sSOI). In this paper, the process parameters with halo implantation and sSOI were used. The effective simulation was performed by using ATHENA process simulator to modify theoretical...
An anechoic chamber is considered good when there is no signal reflection inside the chamber and also when there is no incoming signal from outside the chamber. The key element inside an anechoic chamber is the absorbing material. The evaluations of mini anechoic chamber fitted with coated absorbers were carried out by analyzing the absorption performance. The study includes the comparison of measurement...
Cervical cancer been known to be the cause of many deaths each year. Screening tests, such as the Pap smear test used for the detection of the precancerous stage are able to avoid the occurrence of cervical cancer. However, the Pap smear test does have some disappointing disadvantages such as the fact that it has less effective slide preparation and also that it is laden with human error. Therefore,...
In this feasibility study, four approaches in implementing speech recognition system for speech modeling are proposed. These approaches are based on data — speaker dependability of speech recognition system. Desired information or features in Mel Frequency Cepstral Coefficient (MFCC) are extracted from the speech samples. For pattern matching, Support Vector Machine (SVM) classifier is used to perform...
Radio Frequency (RF) radiation effects are strictly relying on few critical factors, ie frequency, period of exposure and distance. Certain frequency ranges are absorbed in body tissue more than the other frequency range. The second factor is the duration of exposure. Where, over the period of time, the body will absorb more RF frequencies which hence will worsened the human tissue. The third factor...
The popularity of data warehouses for data analysis has grown tremendously. Data warehouse systems have emerged as the core of management information systems. Data warehouse is part of a larger infrastructure that includes legacy data sources, external data sources, data acquisition software, a repository, analytical tools, and user interface. The difficulties of data warehouse implementations have...
