IGBT induction hardening and its application in Singapore
(The Institution of Engineers, Malaysia, 2010-06)
Induction hardening has come a long way. Whilst the vacuum tube power supply is still commonly used in industries, IGBT power supply is fast gaining industrial acceptance. In terms of power efficiency, the IGBT technology ...
Pengesanan kerosakan dalam rangkaian FTTH dengan keupayaan pemprosesan GUI perisian MATLAB
(The Institution of Engineers, Malaysia, 2010-06)
Kajian ini menekankan pembangunan antaramuka pengguna bergrafik (GUI) untuk Sistem Pengesanan Kerosakan Terpusat (CFDS) dengan menggunakan perisian MATLAB untuk meningkatkan keberkesanan, kelengkapan dan keboleharapan ...
Keutuhan permukaan AISI H13 keluli terkeras dalam proses pemesinan nyahcas elektrik (EDM)
(The Institution of Engineers, Malaysia, 2010-06)
Pemesinan nyahcas elektrik (EDM) ialah proses terma senyap yang menghasilkan beribu-ribu nyahcas elektrik dalam satu saat bagi menghakis keluar isipadu tertentu sesuatu logam. Proses ini digunakan secara meluas dalam situasi ...
Effect of interphase forces on two-phase liquid: Liquid flow in horizontal pipe
(The Institution of Engineers, Malaysia, 2010-06)
A two-fluid model (Eulerian-Elurian model) is used to simulate dispersed two-phase immiscible liquids (oil-water) in a horizontal pipe. Effect of interphase forces (drag, lift and turbulent dispersion) is discussed. In the ...
ARIMA models for bus travel time prediction
(The Institution of Engineers, Malaysia, 2010-06)
In this paper, the time series model, Autoregressive Integrated Moving Average (ARIMA) is used to predict bus travel time. ARIMA model is simpler used for predicting bus travel time based on travel time series data (historic ...
A concept development and proposed design procedure for rocking precast hollow core wall in warehouse
(The Institution of Engineers, Malaysia, 2010-06)
Precast hollow core unit is commonly used in the construction of flooring system in precast reinforced concrete building in Malaysia. One of the technical challenges is to design and use precast hollow core unit without ...
Optimisation of hydrolysis conditions for ethanol production from sorghum starch
(The Institution of Engineers, Malaysia, 2010-09)
The conversion of starch to sugar can be achieved by hydrolysis process. The two-step enzymatic hydrolysis of sweet sorghum was performed by commercially available α-amylase and glucoamylase. An optimisation study was ...
Production of non shredded empty fruit bunch semi-compost
(The Institution of Engineers, Malaysia, 2010-12)
Composting of the empty fruit bunch (EFB) with the palm oil mill effluent (POME) could simultaneously treat the solid and liquid waste from palm oil mill. With the aim to reduce the composting yard area, production of ...
Inherent occupational health concept for chemical processes: A new perspective
(The Institution of Engineers, Malaysia, 2010-09)
The concept of inherent safety was known since the last few decades. The idea was quickly spread from the origin UK to the USA and later, to the other parts of the world. The idea was then extended to environment and ...
Nitrate-nitrogen concentration variationin groundwater flow in a paddy field
(The Institution of Engineers, Malaysia, 2010-12)
This study was carried out to evaluate the influence of groundwater on nitrate-nitrogen concentration in a paddy field. Fertiliser if applied excessively can cause leaching into the soil and will penetrate deep into the ...
