Erosion is a common problem occurring on construction sites. It is a leading cause of water quality dilemmas in our water bodies. Our soils will become vulnerable to erosion as when construction activity removes or disturbs vegetative cover, high rainfall intensity and the failure of the sediment basins to function effectively on site. Vegetative covers shield soil surface from the impact of rain,...
Nanocrystalline materials have gained importance to be developed due to their significantly enhanced properties compared to the polycrystalline materials. Electrodeposition has a special role in synthesizing the nanocrystalline materials. In current review, the superiority of electrodeposition technique in producing various nanocyrstalline materials that exhibit improved characteristics compared to...
The novel contribution of this paper is the application of natural fiber (Silk) as a braided sleeve for the PAM. A simple artificial muscle with internal core of silicon rubber netted by hand woven natural fiber (Silk) was fabricated. A suitable experiment was conducted to collect the displacement data which were produced by Silicon Pneumatic Artificial Muscle (SPAM) with various compressed air pressures...
This study deals with noise removal methods on radiographic image which acquired using μ-focused digital radiography machine. The purposes of the study are to enhance the quality of radiographic image using noise removal methods and analyze the image quality using error measurement metrics. Median, gaussian, average and circular averaging filters are the noise removal methods applied on original radiographic...
Currently, the distance related to time and location between distributed software development teams is considered contributing to the chaotic environment of Global Software Development (GSD). Furthermore, when it involves using Agile method where communication is crucial between developers and customers. This paper aim to discussed the issues that have occurred related to the communication in Agile...
Recurrent neural network (RNN) is an efficient tool not only for modeling production control process but also for modeling services. In this paper the combination model of RNN, regression and stepwise regression analysis (SRA) were employed in order to predict the variables of process control chart. Therefore, one maintenance process in workshop of Esfahan Oil Refining Co. (EORC) was taken for illustration...
Effective task scheduling is an important matter for the performance of Grid computing. At the same time, researchers are encountering issues and challenges when dealing with Grid Task Scheduling (GTS) because of various factors or constraints that influence GTS. This is due to the fact that there is an assortment of characteristics and types of scheduling in Grids. This paper reviews the GTS problems...
This paper present the Gilbert mixer which is a transistorized circuit used as an analog multiplier and frequency mixer. The advantage of this circuit is the output current is an accurate multiplication of the (differential) base currents of both inputs As a mixer, its balanced operation, cancels out many unwanted mixing products, resulting in a "cleaner" output. Effort has been taken to...
Are trust and satisfaction important in consumers' electronic commerce acceptance procedure? What are the antecedents of trust and satisfaction in this context? How do trust and satisfaction affect the Internet consumer's purchasing decision? To answer these questions, we develop a theoretical framework describing the trust-satisfaction based decision-making process a consumer uses when making a purchase...
The Central Bank of Malaysia has approved the application of BBA in all financial institutions. Nevertheless, despite it being deemed to be a Shari'ah compliant instrument, the validity of the contract in its essence or even in its execution has been repeatedly challenged in a number of cases in Malaysia. This paper discusses on the importance of understanding the significance of the BBA in the eyes...
A hybrid genetic algorithm is proposed to solve a coordinated production and transportation problem. The problem considered is a mixed integer linear programming problem, which coordinates the production planning of finished products and intermediate products in a process industry, also consists of transportation between the facilities that produces intermediates and finished products. The results...
Halal supply chains include stages from procurement and preparation of genuine halal ingredients to the manufacturing and delivery of final products to customers. Hence, this study investigates the critical point of processed food that attribute to “halal compliance” throughout the halal supply chain. The halal compliance critical control point (HCCCP) analysis was conducted through observations and...
Overloaded vehicles may cause excessive wearing and damages to pavements, roads and bridges. They also threaten the road safety and contribute to several fatal accidents, thus the governments around the world have implemented axle load limitations. This paper investigates the overloading level at the southern part of North-South Expressway in Malaysia. The data were gathered from three survey stations...
Sewage treatment plant (STP) operators are exposed to variety of hazard during wastewater processing. The aim of this study is to identify and manage these hazards, particularly in a local STP in Malaysia, through Occupational Health and Safety Management System (OSHMS). Initially, reported hazards data were collected via review of literatures, questionnaire distribution and interview with experts...
Nowadays, there are many design that has been produced by bus manufacture. The design however not focusing on the aesthetic only, but it must fulfill all the criteria needed like the material and aerodynamically efficient design. The statistic from Road Safety Department of Malaysia shows that the buses that were involved in accident were increasing from 2005 until 2007. There are many factors of...
This work presents a Fault Detection and Diagnosis (FDD) system that uses a combination of discrete wavelet transform and auto-associative neural network. The neural network is trained by Levenberg-Marquardt (LM) algorithm. As a case study, it considers a 5.2MW Siemens Taurus 60S industrial gas turbine. The work is unique in the sense that it addresses the signals in the gas path, generator coils,...
Due to the evolution of electronics and measurement processes, today there are many systems and methods that can be used for measuring airflow, such as the method of differential pressure across of a pneumotachograph or measurements using various anemometers. This research proposes the design and development of a system for measuring respiratory flow using data fusion of information from the Transit...
Freight movement by truck is the common mode in freight distribution due to its flexibility and cheap prices. However, the importance of freight movement by trucks is often not fully understood. This paper thus seeks examines the factors threatening freight movement by trucks that influence the delivery effectiveness. The prescription in this paper is based on the syntheses of critical analyses of...
Palm oil industry contributes significantly to Malaysian economy. However, there seem to be very few studies conducted on improving the palm oil production process. Specifically, there is seemed to be lacked of studies on the application of simulation modelling in improvement activities conducted on palm oil mills. This study addressed this gap by demonstrating the application of simulation modelling...
