Abstract: Mobile radio systems have shown rapid growth and hence increase the awareness for more efficient use of spectrum. With the advancements of technology, the development of radio systems that is dynamic and efficient in terms of spectrum usage can be realized. Cognitive radio system is one of the advancement that enhanced the adaptive capabilities of the systems that make the usage of spectrum more efficient, versatile and flexible. It also able to adapt their operations based on its internal and external factors by sensing its environment. The cognitive radio systems may be a solution for the spectrum scarcity faced by developer to tackle the issue of signal propagation and bigger coverage for broadband internet access. This paper will addressed the cognitive radio technology for ubiquitous broadband wireless internet access.
Demand for Food Safety Attributes for Vegetables in Malaysia
Ahmad Hanis Izani Abdul Hadi
EnvironmentAsia , 2010,
Abstract: In a developing economy like Malaysia with rising per capita income, there have been changes in the consumer demand for food attributes such as safety, freshness, appearance and texture. This study investigated the demand for food safety attributes for vegetables. The results suggested that food safety attributes were ranked the highest for leafy and root vegetables, and ranked second behind freshness for fruit vegetables. Consumers were also willing to pay premium prices for the safety attributes. The findings would have positive implications for the agrifood industry if it responds effectively to translate into business opportunities to these changes.
Termite Incidence on an Araucaria Plantation Forest in Teluk Bahang, Penang

Insects , 2011, DOI: 10.3390/insects2040469
Abstract: A study was carried out to evaluate the incidence of termite attack on an Araucaria cunninghamii plantation at Teluk Bahang Forest Park (TBFP), Penang. The hilly plantation area was surveyed to determine the diversity of termite species present. Termite specimens were collected from standin? Araucaria trees, underground monitoring (aggregation) stations, fallen logs, forest litter and mounds (nests). Seven species of termites were identified from 6 genera; Coptotermes curvignathus, Schedorhinotermes medioobscurus, Schedorhinotermes malaccensis, Odontotermes sarawakensis Parrhinotermes aequalis, Macrotermes malaccensis and Hospitalitermes hospitalis. A total of 289 Araucaria trees were inspected for signs of termite attack. Termite infestation of trees was determined mainly by the presence of mud on the trunk, but particularly around their butts at ground line. The most dominant termite species discovered infesting the Araucaria trees was Coptotermes curvignathus; accountable for 74% of all infestations. Schedorhinotermes medioobscurus and Odontotermes sarawakensis were commonly found infesting dead trees and/or tree stumps. Approximately 21.5% of all Araucaria trees in the plantation forest at Teluk Bahang were infested by termites.

Vulnerability Analysis of Wide Area Measurement System in the Smart Grid  [PDF]
Mohd Rihan, Mukhtar Ahmad, M. Salim Beg
Smart Grid and Renewable Energy (SGRE) , 2013, DOI: 10.4236/sgre.2013.46A001

The smart grid will be a power grid more “aware” of its operating state and having the ability to self-heal. These features may be incorporated into the grid by implementing a phasor measurement units based wide area measurement system. Such a system will help in better real time monitoring and control of the grid. However, the wide area measurement system is subject to challenges with respect to its security. In this paper, a comprehensive analysis of security issues with a wide area measurement system is presented and the research efforts required to be taken are identified. Moreover, the effect of communication failure on a PMU installed system has been presented using integer linear programming.

ESL Teachers’ Experience in Teaching Pupils with Dyslexia in Mainstream Classrooms  [PDF]
Suhana Ahmad, Manisah Mohd Ali, Khazriyati Salehuddin
Creative Education (CE) , 2018, DOI: 10.4236/ce.2018.914158
Abstract: In Malaysia, pupils with dyslexia mostly learn English as a second language (ESL) in mainstream classrooms together with other children. It is known that language learning is the biggest struggle for pupils with dyslexia and learning ESL is even more challenging for them. This paper aims to explore three ESL primary school teachers’ experiences in teaching pupils with dyslexia, particularly the challenges they encounter as well as the strategies they use to assist them in the teaching and learning process. In-depth interviews were conducted with the teachers for the data collection. The findings show that those ESL teachers find it challenging to teach pupils with dyslexia and they are lacking effective teaching methods to apply in the classroom to support the students. Several recounts of teaching experiences show that ESL teachers need more support in terms of training and professional development to ensure literacy skills mastery among pupils with dyslexia.

Teachers’ Competencies in Teaching and Learning History  [PDF]
Mohd Fauzi Bin Ali, Abdul Razaq Ahmad, Ahmad Ali Seman
Open Journal of Social Sciences (JSS) , 2017, DOI: 10.4236/jss.2017.58018
Abstract: This article reviews the teachers’ competencies in teaching and learning History which focuses on contribution of teachers’ knowledge towards application in teaching and learning process namely pedagogy, patriotism, teaching aids, information communication and technology (ICT) and curriculum contents. This survey adapted questionnaire as the main instrument. Stratified random sampling technique was utilized to randomly select 850 teachers of secondary school from four different zones in Malaysia. The data was analyzed using SPSS version 22.0 involving multiple regression analysis. The results of the pilot study show that all constructs were examined at the reliability level of between 0.794 to 0.832. The analysis revealed that all application aspects showed a significance correlation with knowledge competence. Findings showed that the teacher’s knowledge about the application of History pedagogical competence gave the highest contribution as compared to the patriotism, the use of teaching aids and information and communication technology (ICT) as well as curriculum content. This study implies that a more systematic and holistic program should be formulated and implemented to ensure that the teachers will fully master the strategies, techniques and methods which are the key aspects of professionalism for History teacher.
Sewage Sludge as a Renewable Resource for Citric Acid Production: Optimization of Supplementary Nutrients
Nur Hanis Mohamad Hanapi,Md. Zahangir Alam,Mohd Ismail Abd Karim
Journal of Applied Sciences , 2011,
Abstract: The optimization of supplementary nutrients in the sewage sludge as a basal medium was carried out to determine the media components on the citric acid production. Two statistical designs were employed in the citric acid productions which are Plackett-Burman (PB) and Central Composite Design (CCD). For the media screening, the two-level PB design was applied. Under the experimental conditions, it was observed that total suspended solids of sewage sludge (TSS), sugar, cassava, methanol, potassium di-hydrogen phosphate and urea to be the major factors in maximizing citric acid production. A study of single factor was conducted to find the optimum ranges of parameters for citric acid production followed by the Central Composite Design (CCD) under the responses surface methodology. A polynomial model was created to correlate the relationship between two factors (sewage sludge TSS and sugar) and citric acid production. The optimum yield of citric acid, 29.12 g L-1 was produced with 0.8% TSS sewage sludge and 7% sugar in four days of fermentation. The determination of coefficient (R2) from the analysis was 0.9527, indicating that the model of this experiment is significant. This study shows an effective solution to the sludge management for further development through the production of citric acid.
