#### Kinematic and Dynamic Analysis of the Gait Cycle of Above-Knee Amputees

(Sharif University of Technology, 2006-07-01)

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, 2006-07-01)

By application of Cone Penetration Test (CPT) data for shallow foundation (footing) design, the problems of providing representative undisturbed samples and, rather, varphi-N coefficient relations will be eliminated. An ...

#### Simulation of Interdendritic Liquid Permeability for Low and High Solid Fractions During Solidification of Mushy Alloys

(Sharif University of Technology, 2006-07-01)

A numerical model has been developed for the determination of liquid flow permeability through columnar dendrite during growth and segregation in Al-Si alloys. Therefore, in the present work, two separate computational ...

#### Improved Ant Colony Optimization Algorithm for Reservoir Operation

(Sharif University of Technology, 2006-07-01)

In this paper, an improved Ant Colony Optimization (ACO) algorithm is proposed for reservoir operation. Through a collection of cooperative agents called ants, the near-optimum 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, 2006-07-01)

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 (pre-loading) procedure and under ...

#### Numerical Solution of Compressible Euler Equations for Gas Mixture Applications

(Sharif University of Technology, 2006-07-01)

A computer code, based on Euler Equations in generalized curvilinear coordinates, has been developed to resolve binary perfect gas mixture flows. The capability of modeling various mixture effects is built in the algorithm ...

#### Dynamics Modeling of

(Sharif University of Technology, 2006-07-01)

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 ...

#### Application of a Genetic Algorithm to Storm Sewer Network Optimization

(Sharif University of Technology, 2006-07-01)

In this paper, a genetic algorithm is developed for the optimal design of storm water networks. The nodal elevations of the sewer network are taken as the decision variables. A steady state simulation code is used to analyze ...

#### Effect of Unsteady Friction Models and Friction-Loss Integration on Transient Pipe Flow

(Sharif University of Technology, 2006-07-01)

When velocities in the piping systems change rapidly, spectacular accidents occur, due to transient-state pressures where the elastic properties of the pipe and liquid must be considered. This hydraulic transient is commonly ...

#### Prediction of a Soil-Water Characteristic Curve Using a Genetic-Based Neural Network

(Sharif University of Technology, 2006-07-01)

In this paper, a Genetic-Based Neural Network (GBNN) is employed to predict the soil-water characteristic curve of unsaturated soils. A three-layer network has been trained by genetic algorithm and its topology is determined ...
