- Measurement of energy requirements for size reduction of palm kernel and
groundnut shells for downstream bioenergy generation
Abstract: The study estimated the amount of energy required for grinding palm kernel shell and groundnut shell using laboratory hammer mill and also characterize their ground physical properties. The material type and hammer mill screen aperture significantly influenced the energy requirement for grinding the two materials. For a given screen aperture size, groundnut shell consumed more energy than pa...

- The spraying field characteristics and distribution of deposition of
droplets of electrostatic oiler
Abstract: Electrostatic oiler are made as the research object, the multiple field spray characteristics of air flow field, electric field and discrete fog field in the process of spraying were analyzed. The influence of electrostatic spray deposition characteristics has been studied by changing the electrostatic voltage and electrode gap. The experiment about electrostatic oil spray has been verified....

- Comparison of acoustic emission parameters for fiber breakage and
de-lamination failure mechanisms in carbon epoxy composites
Abstract: Acoustic emissions (AE) generated by a structure under stressed condition provide a passive method to understand the flaw growth phenomenon. In complex structures, such as composites, characterisation of AE signals generated by various failure mechanisms enhances such understanding. Sample level tests have been carried out on carbon epoxy unidirectional laminate in longitudinal direction of ...

- Catalytic wet peroxide oxidation of maleic acid: Characterization of
copper/micelle templated silica-3-aminopropyltrimethoxysilane and kinetics
Abstract: The study of catalysts enables the catalyst scientist to identify and understand the important steps such as active sites and stages in a catalysts lifetime. It is thus possible for scientists to design in more rational way, new and efficient catalysts. Therefore, the aim of this study was characterization of copper/micelle templated silica-3-aminopropyltrimethoxysilane (Cu/MTS-AMP) catalyst...

- Enhancement or suppression of dehumidification process by surface
Abstract: In many engineering applications, either the suppression or the enhancement of dehumidification is desired. If so, the dehydration in air-conditioned space can be solved, less condensation water pollution can be achieved, or the dehumidification process can be more efficient. In this study, the effects of various surface treatments were explored to enhance or suppress the condensation. It wa...

- Cement production optimization modeling: A case study BUA plant
Abstract: This paper deals with cement production optimization modeling using Particle Swarm Optimization (PSO) and the results was compared with Genetic Algorithm (GA) and Pattern Search (PS). This optimization modeling took into account mixtures of primary fuel (mineral coal, pet-coke and heavy oil) and its alternative fuel which is agricultural waste (rice husk, sugar waste and ground shell). The o...
