Warpage minimisation on side arm using response surface methodology (RSM)
Catheter manufacturing process requires the use of mould called side arm through latex dipping process. Manufacturing process of a nylon PA66 - side arm via an injection moulding often leads to undesirable warpage. This ... -
Waste seashell as calcium oxide catalyst for bio-oil production from empty fruit bunch
Oil palm waste could be converted into bio-oil through pyrolytic process due to its renewable resource to ensure continuity and capacity for renewable-energy solution. It is a great challenge to convert empty fruit bunch ... -
Water absorption behaviour and its effect on the mechanical properties of hybrid interwoven cellulosic fibre composites
With aim to fulfill the public need that eager for ‘green product’, natural based fibres started to receive attention to substitute synthetic fibres as reinforcement in composites. Natural fibres is relatively cheap, easy ... -
Wave machine as teaching and learning kit
This study is aimed to develop a mechanical wave machine for educational purpose, particularly for school and matriculation students. The basic properties of waves such as wavelengths and amplitudes are directly observed ... -
Wavelet based image denoising using raspberry PI
There has been a huge demand for effective image restoration techniques since the increase in the production of the digital movies and images. No matter how good cameras are, an image improvement is always desirable to ... -
Wavelet image compression implemented using Raspberry PI
An image contains large size of digital data and it is necessary to reduce digital data volume by using image compression method in order to reduce storage size and reduce data transmission time. This project mainly ... -
Wearout reliability studies of bonding wires used in nano electronic device packaging
(Universiti Malaysia Perlis (UniMAP)Institute of Nano Electronic Engineering, 2014)Conventional bare Cu bonding wires, in general, are more susceptible to moisture corrosion compared to gold (Au) and Cu wires. There is very limited knowledge based reliability studies which have been carried out on 1st ... -
Web-Based Data Acquistion System using a 32 bit Single Board Computer and GNU/LINUX
(Universiti Malaysia PerlisSchool of Computer and Communication Engineering, 2009)Most of the previous research in Data Acquisition System (DAS) had used Personal Computers (PCs) as hardware platform which were bulky and not portable. In this research, a Portable Embedded Sensing System (PESS) has been ... -
Weighted linear goal programming approach for maximising profit in industry
Nowadays, in the competitive world of marketing and globalization optimizing the budgetary planning process is an essential criterion that is considered by industries in order to produce high quality products while ... -
Wifi-UHF transceiver design for 650-680 MHZ television white space (TVWS) spectrum application
Studies have sparked an interest to look further into the possibility of research to make beneficial of underutilized Television White Space (TVWS) frequency band of 470 MHz-770 MHz to substitute the 2.4 GHz Wi-Fi which ... -
Wind turbine constant voltage controller using modified SHEPWM technique
The major challenges in designing the controller for wind turbine are fluctuations of the wind speed and the harmonic contents of the output voltage. The fluctuations of the wind turbine speed results in inconsistency ... -
Wireless heart rhythm abnormality monitoring kit based on Raspberry PI
According to statistics, heart diseases kill about 29,360 people every year in Malaysia and about 600,000 people in America. Heart monitoring kits are only available for bedridden patients, and the traditional heart ... -
Wireless power transfer for low power device using magnetic resonant coil
The power is transferred wirelessly through a magnetic resonant coil as an antenna to transmit and receive the energy. This method no longer need complicated with the cable passing around us, with wireless electricity we ... -
Wireless Rogowski coil sensor based on partial discharge detection signal for on-line condition monitoring in the medium voltage power cables
Partial discharge (PD) measurement provide a valuable information for assessing the insulation health in high voltage (HV) power system. In this research, a novel wireless Rogowski coil (RC) sensor based on PD detection ... -
XML cleaning model for data quality improvement using conditional integrity constraints
Extensible Markup Language (XML) is emerging as the primary standard for representing and exchanging data, with more than 60% of the total, XML considered the most dominant document type over the web; nevertheless, their ...
