Degradation of phenol through solar-photocatalytic treatment by zinc oxide in aqueous solution
(Taylor and Francis Ltd., 2015-05-08)
Phenol-containing wastewater is only allowed in a very small amount either in sewage or industrial effluent due to the hazardous effect towards the environment. The objective of this study was to investigate the photocatalytic ...
Effects of synthesis Ni doped Tio2 on Photocatalytic degradation process
(AENSI Publisher (American-Eurasian Network for Scientific Information, 2014)
Titanium is opropoxide, Ethanol, Acetic acid and nickel chloride hexahydrate were used as reagents. The objectives of this study is to synthesize TiO2 and Ni doped TiO2 powders by using reflux sol-gel method and to compare ...
Bee algorithm integrated with system identification technique for modelling dynamic systems
(Asian Research Publishing Network (ARPN), 2016-04-20)
System identification has been widely used in modelling dynamic system whereby the input-output data from real system are undergo the model structure selection, parameter estimation and model validation procedure. However, ...
Three-phase 3D modelling of a laser cutting process using Smoothed Particle Hydrodynamics (SPH)
(Laser Institute of America, 2012)
Smoothed Particle Hydrodynamics (SPH) is used to develop a numerical model to simulate the three-phase laser cutting process for medical coronary stent manufacture. The open-source code SPHysics is used to model the ...
Determination performance of thermoacoustic heat engine simulation by delta EC software
(Trans Tech Publications Ltd, 2015-05)
Thermoacoustic Heat Engine probably the most efficient energy source for electronic devices for the next 10 year ahead that require small amount of electrical energy to operate. This study was to simulate the Thermoacoustic ...
Active vibration control of a flexible beam using system identification and controller tuning by evolutionary algorithm
(SAGE Publications Inc., 2015-07)
This paper presents a new approach of proportional-integral-derivative (PID) controller tuning via an evolutionary algorithm that optimally suppresses the vibration of a flexible beam system using a piezoelectric actuator. ...
Laser marking equipment process $0 cost productivity improvement
(Institute of Electrical and Electronics Engineers (IEEE), 2014)
Semiconductor manufacturing in an Assembly and Test Manufacturing (ATM) environment is becoming more challenging with continuous pressure of lowering overall operating cost and striving for perfect quality in the hope of ...
Corrosion resistance by sodium metavanadate for AZ91D magnesium alloy
(Trans Tech Publications, 2014-06)
An oxide film was prepared on AZ91D magnesium alloy by anodizing in solution containing sodium metavanadate (NaVO3). The corrosion resistance of the substrate was investigated at a fixed current density 10 mA/cm2 for 5 ...
Suspended growth kinetic analysis on biogas generation from newly isolated anaerobic bacterial communities for palm oil mill effluent at mesophilic temperature
(Royal Society of Chemistry, 2014)
The anaerobic degradation of palm oil mill effluent (POME) was carried out under mesophilic temperature in an anaerobic suspended growth closed bioreactor (ASGCB). Monod model was applied to describe the kinetic analysis ...
Artificial aeration to enhance the mineralization of mono azo (methyl orange)-containing wastewater using recirculated up-flow constructed wetland
(Gh. Asachi Technical University of Iasi, 2014)
The aim of this study is to evaluate the treatment performance of mono azo dye Methyl Orange (MO)-containing wastewater by recirculated up-flow constructed wetland (UFCW) with and without supplementary aeration. The ...
