Simulation of Interdendritic Liquid Permeability for Low and High Solid Fractions During Solidification of Mushy Alloys
(Sharif University of Technology, 20060701)A numerical model has been developed for the determination of liquid flow permeability through columnar dendrite during growth and segregation in AlSi alloys. Therefore, in the present work, two separate computational ...

Prediction of a SoilWater Characteristic Curve Using a GeneticBased Neural Network
(Sharif University of Technology, 20060701)In this paper, a GeneticBased Neural Network (GBNN) is employed to predict the soilwater characteristic curve of unsaturated soils. A threelayer network has been trained by genetic algorithm and its topology is determined ...

Improved Ant Colony Optimization Algorithm for Reservoir Operation
(Sharif University of Technology, 20060701)In this paper, an improved Ant Colony Optimization (ACO) algorithm is proposed for reservoir operation. Through a collection of cooperative agents called ants, the nearoptimum solution to the reservoir operation can be ...

Stress Variation in the Flange of a Gasketed Flanged Pipe Joint During Bolt up and Operating Conditions
(Sharif University of Technology, 20060701)This paper presents results of an experimental study of the behavior of the stress variation at the flange and attached pipe section of a gasketed flanged pipe joint during both the bolt up (preloading) procedure and under ...

Dynamics Modeling of
(Sharif University of Technology, 20060701)This paper presents an effective approach for kinematic and dynamic modeling of high mobility Wheeled Mobile Robots (WMR). As an example of these robots, the method has been applied to the CEDRA rescue robot, which is a ...

Comparing Shape and Image Reconstruction in Electrical Capacitance Tomography
(Sharif University of Technology, 20060701)Electrical Capacitance Tomography (ECT) is an imaging technique that maps the electrical permittivity contrast of the object. This paper studies an image and a shape reconstruction method for ECT. For image reconstruction, ...

Effect of Unsteady Friction Models and FrictionLoss Integration on Transient Pipe Flow
(Sharif University of Technology, 20060701)When velocities in the piping systems change rapidly, spectacular accidents occur, due to transientstate pressures where the elastic properties of the pipe and liquid must be considered. This hydraulic transient is commonly ...

Effects of Turbulent Models and Baffle Position on the Hydrodynamics of Settling Tanks
(Sharif University of Technology, 20060701)In this paper, the numerical results of hydrodynamic modeling of primary settling tanks are presented. The flow field is assumed to be incompressible and nonbuoyant. The effects of two different types of turbulence model, ...

Kinematic and Dynamic Analysis of the Gait Cycle of AboveKnee Amputees
(Sharif University of Technology, 20060701)The change of gait pattern and muscular activity following amputation is thought to be responsible for the higher incidence of joint degenerative disorders observed in amputees. Considering the lack of consistent data in ...

Analytical Model for the Ultimate Bearing Capacity of Foundations from Cone Resistance
(Sharif University of Technology, 20060701)By application of Cone Penetration Test (CPT) data for shallow foundation (footing) design, the problems of providing representative undisturbed samples and, rather, varphiN coefficient relations will be eliminated. An ...

Numerical Solution of Compressible Euler Equations for Gas Mixture Applications
