Perbandingan jumlah kandungan elektron di atas variasi longitud khatulistiwa dan latitud menggunakan model IRI, NeQuick dan data IONEX
(The Institution of Engineers, Malaysia, 2010-06)
Pengetahuan mengenai jumlah kandungan elektron (total electron content, TEC) di sesebuah kawasan terutamanya di kawasan khatulistiwa adalah penting bagi pembangunan sistem komunikasi menggunakan lapisan ionosfera. Kajian ...
Physical and thermochemical characterisation of Malaysian biomass ashes
(The Institution of Engineers, Malaysia, 2010-09)
The agriculture sector in Malaysia has been growing rapidly over the years and this leads to large amount of agricultural waste. However, sustainable development and increasing fuel demand necessity had identified biomass ...
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 ...

(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 ...
