A simulation package for the transport of high energy muons has been developed. It has been conceived to replace the muon propagation software modules implemented in the detector simulation program GEANT3. Here we discuss the results achieved with our package and we check the agreement with numerical calculations up to 108 GeV .

for designing tillage implements it would be better to estimate soil forces exerted to the implements. many researches showed that numerical method of discrete element method (dem) is the cheapest and fastest technique for modeling granular material such as soil and especially sandy soil. in this study, paraplow and bentleg tines performance was compared with conventional tine using experimenta...

The paper deals with the distributed solution of simulation based nonlinear constrained optimization problems in engineering on a network of workstations. This type of non-linear optimization and control problems in engineering can be generally characterized as non{convex and non-smooth. Additionally, the involved simulation introduces certain numerical "noise\ to the solution process. These ch...

Dense Medium Cyclone is a high capacity device that is widely used in coal preparation. It is simple in design but the swirling turbulent flow, the presence of medium and coal with different density and size fraction and the presence of the air-core make the flow pattern in DMCs complex. In this article the flow pattern simulation of DMC is performed with computational fluid dynamics and Fluent...

Injection Molding is a crucial segment of the plastics industry mainly due to its ability and flexibility to manufacture intricate components at high production rates and also with easy process flow. Injection molding has laid its hands over right from small parts to big machine parts. Plastic side release buckles, commonly employed in standard bags, suitcases and pouches, and are manufactured ...

a linear low density polyethylene (lldpe) production process, including two- fuidized bed reactors in series (fbrs) and other process equipment, was completely simulated by aspen polymer plus software. fluidized bed reactors were considered as continuous stirred tank reactors (cstr consisted of polymer and gas phases). poly-srk and nrtl-rk equations of state were used to describe polymer and no...

The kinematics recursive equation was built by using the modified D-H method after the structure of rehabilitation lower extremity exoskeleton was analyzed. The numerical algorithm of inverse kinematics was given too. Then the three-dimensional simulation model of the exoskeleton robot was built using MATLAB software, based on the model, 3D Reappearance of a complete gait was achieved. Finally,...
