A basic research that descriptive in nature was conducted at a Routine Maintenance Company in East Coast of Peninsula Malaysia regards to inventory management discipline that focused on one high drawing item, which is fluorescent lamp PLL 36 watt. The aims for the study are to determine the EOQ, total annual inventory cost, number of orders and expected time between orders. It was found that the EOQ...
Nowadays, construction waste issues have become a major concerned in most countries to both practitioners and researchers towards a sustainable development. In Malaysia, awareness on the documentation of construction waste generated from construction activities is still lacking although such record may offer a better waste management system. Meanwhile, various models in quantifying the construction...
Langkawi is a resort island in the northwestern part of Malaysia where the island's economy is reliant on agro-based activities and tourism for sustainable development. With the Digital Era, it is important that the indigenous islanders adjust their income generating ways by using information and communication technology (ICT) for better capacity building. This is in line with the government's four...
Management research has indicated that others' cognitive perceptions of an actor's central network position (CP) are more strongly associated with individual power than actual network position. Revisiting a classical dataset, this paper does similar findings. It is suspected, however, that CP may not merely be associated with power, but it rather measures the concept itself. Using external criterion...
Synonymous codon usage is a ubiquitous phenomenon in the genes of organisms. It is a phenomenon that is closely associated with gene expression level, understanding of which may have practical applicability in biomedicine sector. In this study, the synonymous codon usage in Nlrp1 gene was investigated. Because Nlrp1 gene encodes for NLRP1 inflammasome, which is an important cytosolic pathogen sensor...
In bioremediation, oil degrading microorganisms are applied to remediate contaminated soil. Air is an essential factor for activation of degrading microorganisms. Adding some bulky wastes or by-products which enhance the air circulation in the system is one of the economical approaches for aeration. In this study, co-composting of oil sludge contaminated soil from a local refinery plant was studied...
The aim of this study is to review on mechanism of ultrasonic irradiation in enzymatic esterification reaction, the effect on enzyme activity and stability and also rate of reaction in ultrasonic assisted enzymatic reaction. Conventional enzymatic esterification system using immobilized enzyme generally have a limitation in internal mass transfer that might plausible to reduce rate of ester formation...
The non-destructive technique (NDT) such as for determined the velocity is an easy technique to apply and they are increasingly being used in geotechnical engineering. Most researchers studied the relations between rock properties and velocity and found that the velocity is closely related with rock properties. Wave velocity can be measured directly or indirectly in the laboratory. In this study,...
Thin film of Polyaniline (PANi) was electrochemically deposited at constant potential of +0.75 V for 60 s. The surface morphology of the prepared thin film was imaged using Field Emission Scanning Electron Microscopy (FESEM). The electrochemical measurements such as electrochemical behavior and electrochemical stability were measured using Cyclic Voltammetry (CV) technique. The result showed that...
The inferior properties of the recycled concrete aggregate (RCA), as compared with the natural aggregate, are caused by the presence of the porous residual mortar with numerous micro-cracks, which is attached to the original aggregates. The inferior qualities of RCA have limited its use in structural concrete production. Thus, this study investigated the feasibility of combining two different methods...
Whilst a normal inverter converts the DC voltage into AC voltage, an off grid inverter occupies input from either solar panel or wind turbine. This paper is about the design and simulation of a bi-input inverter using PV and Wind power system. The overall design will result in a regulated AC output load for AC grid connected system. This paper also discusses on two circuits which is charge controller...
In this paper, new method of Colpitts oscillator designing through combination of Genetic Algorithm and Artificial Neural Network (ANN) has been suggested. The Thevenin's resistors for the common base Colpitts oscillator are optimized through application of GA and ANN. The developed common base Colpitts oscillator has shortest transient time response and stable Direct Curent (DC) stability in the...
Portable document format (PDF) is an electronic file format which is used for representing two-dimensional documents independent of software, hardware, and predominant formats for creating, storing and delivering electronic documents. The PDF/X family of standards was and is continuing to be, developed by ISO/TC130, Graphic technology. The goal is to provide an efficient vehicle for the exchange of...
Burst allocation is one of the important parameter that affects the performance of the Mobile WiMAX systems. The burst allocation algorithm is responsible about calculating the appropriate dimensions and location of each user's data to construct the bursts within the downlink subframe in term of the number of slots per user. Resource wastage in the form of unused and unallocated slots is a common...
Increase of awareness among people has increased the demand for green products. Other synthetic materials such as plastic and fibreglass has been reduced because of the environmental concern. Reinforcement with other green materials such as lignocellulosic materials has been done to reduce the dependency on synthetic material. Kenaf (Hibiscus cannabinus L.) fibres have the biggest potential to be...
Peer-to-peer systems become a promising alternative for traditional server-client system to providing video streaming; the topology is the one of most important part of these systems. The proposed topology presented in this study is an adaptable topology affected by two factors: video bitrate and upload bandwidth for each single peer in the network. The connection between peers will be changed based...
The Private Financial Initiative (PFI) program has been implemented by many developed countries throughout the world as an innovative way for the governments to improve future public service delivery and infrastructure procurement. However, the idea is just about to germinate in Malaysia and its success is still vague. The major phase that needs to be given main attention in this agenda is value for...
Animated pedagogical agent (APA) is a vital instructional tool in kindergartens. However, most kindergarteners are still conventionally taught basic second language words by flashcards especially by those in rural areas. Hence, this research explored the use of APA on teaching rural kindergarteners second language basic words. The software was built and tested on 40 kindergarteners of a kindergarten...
In order to meet the increasing demand and stringent design requirements for coverage expansion, throughput and capacity enhancement relay Node (RNs) has been considered as a promising solution to LTE-A Point-to-Multi-Point (PMP) networks. In this paper two scenarios are proposed, at the first scenario this work introduced the performance analysis of two-way Multiuser system of half duplex to AF (Amplify...
This research analyzes the relationship between standards implementation, which is believed to be able to give contributions in value creation process, and organization performance. Mixed method approach was used to deeply investigate field fact through two ways. The first is the quantitative approach using appropriateness testing of EQA Model and organization performance measurement in three case...
