ANZJPH © 2011 Public Health Association of Australia was the causative organism in seven causes, Aeromonas hydrophilia in six and Methicillin-resistant Staphylococcus aureus (MRSA) in one. Cyclone Yasi was the worst storm to hit Far North Queensland in recorded history. Recent weather patterns suggest an increasing freq...

The original cotton particulates analyzer used stationary screens to separate aerodynamically the coarse and fine dust fractions from small samples of cotton. By replacing stationary with rotary screens that were continuously cleaned, larger supplies of respirable dust were obtained without interruption. A ginned and a waste cotton were used to test two methods of separation: a rotating 38-micr...

This paper presents the design procedure and implementation results of a proposed software defined radio (SDR) using Altera Cyclone II family board. The implementation uses Matlab/Simulink, Embedded Matlab blocks, and Cyclone II development and educational board. The design has first implemented in Matlab/Simulink environment. It is then converted to VHDL level using Simulink HDL coder. The des...

Co-firing ramie residue with coal was carried out in a thermogravimetric analyzer and a cyclone furnace to evaluate the effects of coal fraction (0 to 30 wt. %) on combustion performance. Thermogravimetric analysis (TGA) results showed that devolatilisation was the predominant process when the coal percentage in the blend was below 30 wt. %. For pure biomass firing in the cyclone furnace, an op...

Multiobjective optimization of a set of N identical reverse-flow cyclone separators in parallel was carried out by using the nondominated sorting genetic algorithm (NSGA). Two objective functions were used: the maximization of the overall collection efficiency and the minimization of the pressure drop. Nondominated Pareto optimal solutions were obtained for an industrial problem in which 165 m3...

The initiation of a deep and severe impact Mediterranean cyclone in the lee of Atlas Mountains is investigated by a series of numerical experiments using the MM5 forecast model. Roles of orography, surface sensible heat flux and an upper-level potential vorticity anomaly are identified using factor separation method. Results of model simulations show that orography blocking is responsible for g...

The high-speed swirling flow field in the cyclone oil-gas separator will cause the breakup of oil droplets, thus reducing the separation efficiency. In this paper, the performance of an oil-gas cyclone separator was investigated through both numerical simulations and experiments with considering the breakup of oil droplets in oil-gas cyclone separators. The gas flow field was simulated using th...

Large amount of archived unannotated satellite data is publicly available. The automated retrieval of satellite data from these public domains based on ad-hoc user request is extremely useful to scientists for analysis and as evidence to support scientific hypotheses on weather phenomenon. One efficient approach for such data/information retrieval is to use the publicly available information ab...

The sensitivity of tropical cyclone intensity to ventilation of cooler, drier air into the inner core is examined using an axisymmetric tropical cyclone model with parameterized ventilation. Sufficiently strong ventilation induces cooling of the upper-level warm core, a shift in the secondary circulation radially outward, and a decrease in the simulated intensity. Increasing the strength of the...
