Design of an infrared tomography system for detection of bubbles
(Penerbit UTM Press, Universiti Teknologi Malaysia., 2011-08)
In this study, an optical process tomography with 2 orthogonal projections is being designed to be implemented at a vertical column modelled. The tomography system will be designed from the development of transducer pairs ...
Hardware developments of an ultrasonic tomography measurement system
(International Frequency Sensors Association (IFSA), 2011-01)
This research provides new technique in ultrasonic tomography by using ultrasonic transceivers instead of using separate transmitter-receiver pair. The numbers of sensors or transducers used to acquire data plays an important ...
Functionalised zinc oxide nanotube arrays as electrochemical sensors for the selective determination of glucose
(The Institution of Engineering and Technology, 2011-08)
In the present study, highly oriented single-crystal zinc oxide nanotube (ZnO-NT) arrays were prepared by a trimming of ZnO nanorods along the c-axis on the gold-coated glass substrate having a diameter of 100-200nm and a ...
Investigating the possibility of utilization of kaolin and the potential of metakaolin to produce green cement for construction purposes-A review
(INSInet Publication, 2011-09)
Geopolymers are inorganic alkali aluminosilicate gels, formed from reaction of mineral clays or aluminosilicate-bearing industrial wastes, and treated with alkali silicate solution at 40-80°C. Geopolymers have been studied ...
Fabrication and mechanical properties of composite palm ash mixed with phenolic resins
(International Network for Scientific Information Publication (INSI), 2011-11)
Brake pad is one of the important engineering components in automobile and it is fabricated by combination of various materials. Asbestos is one of the components in brake pad that is harmful to the human. In this ...
Comparative study on thermal, compressive, and wear properties of palm slag brake pad composite with other fillers
(Trans Tech Publications, 2011)
The attractive performance-to-cost ratio associated with the incorporation of waste material in composite formulations used to produce brake pads has stimulated the idea of exploring the possible incorporation of additional ...
Electrical characterization and equivalent circuit analysis of (Bi1.5Zn0.5)(Nb0.5Ti1.5)O7 Pyrochlore, a relaxor ceramic
(The American Institute of Physics (AIP), 2011)
The ac impedance of (Bi1.5Zn0.5)(Nb0.5Ti1.5)O7, a relaxor ceramic with the pyrochlore structure,
has been measured over the temperature range 10–1073K and analyzed using a combination of
traditional, fixed-frequency ...
Potential application of kaolin without calcine as greener concrete: A review
(INSInet Publications, 2011-07)
Kaolin is a white raw material that has an essential constituent which makes it ideal for industrial applications such as green concrete. Based on a historical review, it appears that green polymeric composites created by ...
Optimization of machine tools by using the maximum productivity rate
(INSInet Publication, 2011)
Calculation of the productivity rate and optimization of the operating modes for automatic
machine tools today is complex, and in many cases, an unresolved problem. Most equations for
calculating the optimal machining ...
Effect of ethanol concentration in water coagulation bath on pore geometry of PVDF membrane for Membrane Gas Absorption application in CO 2 removal
(Elsevier B.V., 2011-03)
In this study, polyvinylidenefluoride (PVDF) flat sheet membranes were fabricated by immersing into various concentrations of ethanol in water (M-1:0%, M-2:25%, M-3:50% and M-4:75% respectively) as the coagulation bath via ...
