(Scientific Research, 2012-09)Different signal processing technique performances are compared to each other with regard to separating the mean and fluctuating velocity components of a simulated one-dimensional unsteady velocity signal comparable to ... -
Modeling Evaporating Droplets in Complex Unsteady Flows
(Scientific Research, 2012-06)In many applications, a moving fluid carries a suspension of droplets of a second phase which may change in size due to evaporation or condensation. Examples include liquid fuel drops in engines and raindrops or ice-crystals ... -
Mazumder Effect of Liquid and Gas Velocities on Magnitude and Location of Maximum Erosion in U-Bend
(Scientific Research, 2012-06)Solid particle erosion is a micromechanical process that is influenced by flow geometry, material of the impacting surface, impact angle, particle size and shape, particle velocity, flow condition and fluid properties. ... -
Study of the Different Factors That Influence Jet Pump Performance
(Scientific Research, 2013-06)The objective of this work is to study experimentally the characteristics of jet pump. Suction head, driving air pressure and the percentage of the distance between throat section and nozzle are recorded. The effect of ... -
Drilling Operation and Formation Damage
(Scientific Research, 2013-06)Transport of particle suspensions in oil reservoirs is an essential phenomenon in many oil industry processes. Solid and liquid particles dispersed in the drilling fluid (mud) are trapped by the rock (porous medium) and ... -
Pathogenicity of individual isolates of entomopathogenic fungi affects feeding preference of red imported fire ants Solenopsis invicta
(published online, 2014-01)Seven isolates of entomopathogenic fungi, Isaria fumosorosea (IFCF-H and IFCF-L), Beauveria bassiana s.l. (Bb02 and Bb04) and Metarhizium anisopliae s.l. (Ma01, SM076 and M09), were selected for their pathogenicity against ... -
Biological control of Aphis fabae and Bemisia tabaci by the native isolates of Beauveria bassiana in Kerman province
(published online, 2012-10)In this research, we isolated the pathogenic strain, KB512, of entomopathogenic fungi Beauveria bassiana from soil and insects, which produced aerial and submerged conidia and blastospores in the laboratory conditions. ... -
Approaches to Biological Control of Termites
(University of Hawaiʻi at Mānoa, 2003-01)Biological control refers to the application or manipulation of preda- tors, parasitoids, or pathogens in order to suppress and manage insect populations. The cryptic habits of subterranean termites limit their susceptibility ... -
Two Simple Analog Multiplier Based Linear VCOs Using a Single Current Feedback Op-Amp
(Scientific research, 2010-07)Two simple voltage-controlled-oscillators(VCO) with linear tuning laws employing only a single current feedback operational amplifier (CFOA) in conjunction with two analog multipliers(AM) have been highlighted. The ... -
The Design of an Intelligent Security Access Control System Based on Fingerprint Sensor FPC1011C
(Scientific Research, 2010-07)This paper deals with the design of an intelligent access control system based on the fingerprint sensor FPC-1011C. The design uses the S3C2410 and TMS320VC5510A as the system processor. A fingerprint acquisi-tion module ... -
