Reducing the environmental impact of the flotation of sphalerite : an alternative reagent scheme
(2009)
N-Hydrocinnamoyl-N-phenylhydroxylamine (HCNPHA) was found to float sphalerite without activation by copper sulphate. However, concomitant flotation of sulphidic gangue minerals, such as pyrite, significantly reduced the ...
Catalytic decomposition of ammonia and tar for hot gas cleanup in biomass gasification using activated carbon supported catalysts and natural limonite ores
(2009)
Biomass gasification produces a gas (or syngas) containing primarily CO2, H2, CO, CH4 and (C2+C3), as well as some contaminants such as tars, NH3, H2S and SO2. In order to achieve better efficiencies of the syngas applications, ...
The Correlations and the power characteristics of special classes of binary sequences for multicarrier communications
(2009)
In recent years, multicarrier communication has attracted considerable attention as a promising technology that enables transmission of high data rates. One of major drawbacks of multicarrier communications is the high ...
Location-independent packet scheduling for wireless EPON
(2009)
Ethernet Passive Optical Network (EPON) is the latest access technology, based on IEEE standards, utilizing an optical network architecture optimized for simple, economical delivery of voice, data, and video over native ...
Mobile ontology-based reasoning and feedback health monitoring system
(2009)
As medical technology has developed over the past few decades, the average human life-span has increased and as a side effect, chronic illness has become more prevalent. Many patients now require constant, everyday monitoring ...
Management, environmental and energy considerations for woodwaste
(2009)
Manufacturing operations that process raw wood, such as sawmills and pulp and paper mills, generate wood residue, such as woodwaste, sawdust, shavings, wood chips and off-cuts, also known as woodwaste. The decomposition ...
Catalytic gasification of biomass for the production of syngas with reduced tar formation
(2009)
With increased concerns over greenhouse gas emission and decreasing fossil fuel supplies, biomass is increasingly seen as an alternative option for energy and chemical production. There are several technologies available ...
Autonomous navigation algorithms for indoor mobile robots
(2009)
In many autonomous mobile robotic applications, the capability of finding a good path is of primary importance, especially for the places which are cluttered by random obstacles that may appear on the robot's path.
Effects of nutrients conditions and solids retention time (SRT) on performance and membrane fouling of aerobic membrane bioreactors (MBRs)
(2015-10-21)
This thesis investigated the effect of chemical oxygen demand (COD) to nitrogen ratio (COD:N) in feed on the biological performance of aerobic membrane bioreactor (MBR). Meanwhile, the effects of nutrients condition (COD:N ...
Utilization of coal biomass fly ash in the control and treatment of acid mine drainage
(2009)
This study investigated the feasibility of using coal/biomass fly ash (CBFA) blended with various percentages of mine tailings, bentonite, and glacial till soil to control and treat acid mine drainage (AMD). Applications ...
