. Beta-tricalcium phosphate (P-TCP) has been widely used for biomedical application due to its excellent mechanical strength, good tissue compatibility and outstanding chemical stability. There are several methods to fabricate porous scaffolds including solvent casting, phase separation, rapid prototyping and electrospinning methods. In the present...

Gravity die casting is the technique which enables fabrication of open-cell A356 aluminium foam as a suitable absorber material with good quality performance. A356 aluminium alloy was used with varies amount of sodium chloride (NaCI) particles as a space holder to fabricate the aluminium foam using gravity die casting. Microstructural analysis, por...

Agriculture sensors play an important role in modern agriculture. The use of sensors in various agriculture sectors minimizes the environmental impact on crops, helps in increasing yield and saving cost of operation. Among all agriculture industries in Malaysia, the mushroom industry is a comparatively new and small. As most of the mushroom farms i...

The prediction of compressive stress-induced failures is of concern when designing and constructing facilities in rock for deep underground excavation. The purpose of this study is to model compressive stress-induced failure and fallouts with appropriate material models and strength parameters for deep hard rock tunnel excavation. Three method of n...

The knowing of geological profile ahead of tunnel face is significant to minimize the risk in tunnel excavation work and cost control in preventative measure. Due to mountainous area, site investigation with vertical boring is not recommended to obtain the geological profile for Pahang-Selangor Raw Water Transfer project. Hence, tunnel seismic pred...

The demand of surface area increases rapidly in the urban areas due to the increase in populations. This leads to the shortage of surface area for development in the future. Underground development is one of the solutions to solve the problems, such as the tunnel constructed underground, to provide new spaces for the development without claiming va...

Multiagent system appear in various areas such as cooperative control of unman ned aerial vehicles. autonomous underwater vehiclos, consensus problem of communication networks, formaticn control of mobile robols. Distributed design paradigm is preferred over the centralised approach because the former provides convenient in design, impelementatio...

In this study, novel asymmetric membranes with pre-selective layer consist of electrospun poly(vinyl alcohol) (PVA) nanofibres and electrospun PVA nanofibres integrated with two different types of hydrophilic fillers i.e. micron-si .ed copper benzene-1,3,5-tricarboxylate (Cu­ BTC) and nano-sized carboxyl multi-walled carbon nunotube (COOH-M...

Plant phenotyping studies represent a challenge in agriculture application. The studies normally employ CMOS optical and image sensor. One of the most difficult challenges in designing the CMOS sensor is the need to achieve good sensitivity while achieving low noise and low power simultaneously for the sensor. At low power, the CMOS amplifier in th...

Considerable efforts have been made for the fabrication of up r hydrophobic coating for self-cleaning applications. However,a facile, eco-friendly and cost effective co

In this study, cordierite was prepared by glass-route method using Si02, A1203 and MgO as raw materials. Cordierite powder produced was then used to fabricate 3-D porous cordierite using gel casting method using different amount of GRF (2.5, 4.0 and 6.0g) and dried egg white (DEW) (1.5, 2.5 and 4.0g) as binder to observed their effect on the streng...

The stress-induced failure, such as spalling and rock burst are considered as engineering disasters in deep underground excavations in hard rock. A practical predictive technique or a model to evaluate these stress-induced failures and a spalling strength is a concern in the design of support systems and excavations in underground tunnels. In the p...

This research aims to investigate the presence of four non-linear characteristics (i.e., hysteresis, saturation, creep and vibration) when a piezoelectric patch material is acted as actuator for the AVC of a beam. The parameters such as frequencies and voltages are taken into account for the piezoelectric patch material characterization and the vib...
