Shear strength of 160 MPa steel fibre reinforced reactive powder concrete bridge girders without stirrups
(The Institution of Engineers, Malaysia, 2006-06)The development of ultra-high-strength-high-performance concrete known as the reactive powder concrete (RPC) was originated in the mid 1990’s by the French and now commercialised under the trade name of DUCTAL by ... -
Ann based prediction of blast furnace parameters
(The Institution of Engineers, Malaysia, 2007-03)The paper presents a method to predict blast furnace parameters based on artificial neural network (ANN). The prediction is important as the parameters cause the degradation of the production process. The productivity as ... -
Drill wear monitoring by vibration signature analysis
(The Institution of Engineers, Malaysia, 2007-03)The useful life of a cutting tool and its operating conditions largely controls the economics of the machining operations. Hence, it is imperative that the condition of the cutting tool, particularly some indication as ... -
Investigation of simple cubical space trusses as impact energy absorbers
(The Institution of Engineers, Malaysia, 2007-06)Experimental work on the possible use of cubical space trusses as energy absorbers is described. To this end the crushing behavior of single cubical space trusses welded from mild steel bars was studied experimentally. ... -
Fuzzy logic approach for mobile robot in intelligent space
(The Institution of Engineers, Malaysia, 2008-12)This paper introduces the fuzzy logic approach for mobile robot in intelligent space. There are three major algorithms involved. They are object classification, object tracking and obstacle avoidance. The inputs are ... -
Dual frequency broadband reflectarray element design
(The Institution of Engineers, Malaysia, 2007-06)The bandwidth limitation of a reflectarray is a consequence of the non-linear and high Q variation in the reflection phase which occurs when the element size is changed to produce the required progressive phase distribution ... -
Seismic behaviour of thin/slender concrete walls with monolithic emulation base connections tested on shaking table
(The Institution of Engineers, Malaysia, 2008-06)Two geometrically identical slender precast concrete walls with monolithic emulation base connections were constructed and tested under biaxial loading using two clover displacement control patterns on shaking table. ... -
A practical tool for small and medium enterprise quality performance improvement
(The Institution of Engineers, Malaysia, 2007-09)Quality performance in manufacturing may be assessed in several different ways. The aim of this paper is to present a practical tool that can be used by manufacturing companies, especially Small and Medium-sized Enterprises ... -
Using a fatigue data editing approach for analysing cycle sequence effects in variable amplitude road loadings
(The Institution of Engineers, Malaysia, 2006-06)This paper presents the analysis of cycle sequence effects using variable amplitude (VA) fatigue loadings extracted from a wavelet-based fatigue data editing algorithm, known as Wavelet Bump Extraction (WBE). This algorithm ... -
Rheological properties of SS316l MIM feedstock prepared with different particle sizes and powder loadings
(The Institution of Engineers, Malaysia, 2009-06)Rheological study has been performed experimentally to evaluate the influence of different particle sizes and powder loadings to the rheological properties of SS316L MIM feedstock. The effects of different particle size, ... -
Design and analysis of multi-cavity traditional and h-branching runners for plastic injection mold
(The Institution of Engineers, Malaysia, 2009-06)This paper describes the design and analysis of plastic injection mold balancing runner. The runners were designed based on Ellis Model, a viscosity model of flow network consisting of elements and nodes. 4-coefficients ... -
Applications of GIS and remote sensing in the hydrological study of the Upper Bernam River Basin, Malaysia
(The Institution of Engineers, Malaysia, 2008-03)Rising concern over the degradation of the environment, such as erosion and sediment loads, warrants the integration of the complex and dispersed geographical data sets. This paper describes the use of Geographic Information ... -
Dynamic overturning capacity of rocking precast thin wall structures
(The Institution of Engineers, Malaysia, 2007-09)Most of the damages in precast wall panels occur within the plastic hinge zone (PHZ) which located at one-third bottom height of the wall. Fixed-base monolithic walls panels are commonly used in the construction of low, ... -
Pulsating circular air jet impingement heat transfer
(The Institution of Engineers, Malaysia, 2006-09)The purpose of this study is to determine the effect of pulsating frequencies on the local and average heat transfer characteristics of a heated circular air jet. Pulsation of the air jet was produced by a rotating cylinder ... -
