Study of the Different Factors That Influence Jet Pump Performance
(Scientific Research, 201306)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 ... 
Study on the Relationship between Aspects, Orientation,Type, and Unit Position toward to Indoor Air Quality in Flat
(Scientific Research, 201305)Thermal factor is one of the main factors of the green building concept. The purpose of this research is to test building performance through design aspect that influences thermal comfort, the design aspects include: ... 
Systematization of basic divergent integrals in perturbation theory and renormalization group functions
(Elsevier, 200902)We show that to n loop order the divergent content of a Feynman amplitude is spanned by a set of basic (logarithmically divergent) integrals I (i) log(λ2), i = 1, 2,...,n, λ being the renormalization group scale, which ... 
Two Simple Analog Multiplier Based Linear VCOs Using a Single Current Feedback OpAmp
(Scientific research, 201007)Two simple voltagecontrolledoscillators(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 ... 
Uniqueness of moving boundary for a heat conduction problem with nonlinear interface conditions
(Elsevier, 201001)In this paper, based on the maximum principle and the unique continuation theorem, we present a uniqueness result for a moving boundary of a heat problem in a multilayer medium with nonlinear interface conditions. 
Vehicle and Cargo Scanning for Contraband
(Elsevier, 2017)There is a need to inspect vehicles and their contents for Special Nuclear Material (SNM) and general contraband. The most widely used technology for scanning vehicles, ranging from vans and trucks to railcars, is gammaray ... 
WeisFogh Mechanism Mathematic Model of Wave Power Generation Device
(Scientific Research, 201412)A WeisFogh mechanism wave power generation system is designed, its physical model and mathematical model are discussed, and the component expressions of fluid dynamic expression are derived. Adopting numerical integral ...
