The Research of Performance Comparison of Displacement and Mixing Ventilation System in Catering Kitchen
(Scientific Research, 201307)A commercial kitchen is a complicated environment where multiple components of a ventilation system including hood exhaust, conditioned air supply, and makeup air systems work together but not always in unison. And the ... 
A Simplified Nonlinear Generalized Maxwell Model for Predicting the Time Dependent Behavior of Viscoelastic Materials
(201106)In this paper, a simple nonlinear Maxwell model consisting of a nonlinear spring connected in series with a nonlinear dashpot obeying a powerlaw with constant material parameters, for representing successfully ... 
Simplifying differential equations concerning degenerate Bernoulli and Euler numbers
(Elsevier, 201804)In the paper, the authors signiﬁcantly and meaningfully simplify two families of nonlinear ordinary differential equations in terms of the Stirling numbers of the ﬁrst and second kinds. 
Simulation of Average Turbulent Pipe Flow: A ThreeEquation Model
(Scientific Research, 201403)The aim of this study is to evaluate a threeequation turbulence model applied to pipe flow. Uncertainty is approximated by comparing with published direct numerical simulation results for fullydeveloped average pipe flow. ... 
Some New Results on Prime Graphs
(Scientific Research, 201207)We investigate prime labeling for some graphs resulted by identifying any two vertices of some graphs. We also introduce the concept of strongly prime graph and prove that the graphs Cn, Pn, and K1,n are strongly prime ... 
Stochastic differential equations in a Banach space driven by the cylindrical Wiener process
(Elsevier, 201704)Generalized stochastic integral from predictable operatorvalued random process with respect to a cylindrical Wiener process in an arbitrary Banach space is defined. The question of existence of the stochastic integral in ... 
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 ...
