We perform event-driven molecular dynamics simulations of a system composed by uniaxial hard ellipsoids for different values of the aspect ratio and packing fraction. We compare the molecular orientational-dependent structure factors previously calculated within the Percus-Yevick approximation with the numerical results. The agreement between theoretical and numerical results is rather satisfac...

Experimental approaches in concrete technology are time-consuming, laborious and thus expensive. Developments in computer facilities render possible nowadays realistically simulating the particulate structure and microstructure of cementitious materials. For that purpose, discrete element methods (DEM) are required because of more correctly simulating particle dispersion. Dynamic DEMs like Delf...

Relative frequencies of mechanically stable (MS) packings of frictionless bidisperse disks are studied numerically in small systems. The packings are created by successively compressing or decompressing a system of soft purely repulsive disks, followed by energy minimization, until only infinitesimal particle overlaps remain. For systems of up to 14 particles, most of the MS packings were gener...

The research about membrane-shape related processes is a new fascinating field. Recently an increasing number of lipid-binding domains that sculpt or sense the shape of the membrane have been identified. Most of the studies about membrane-shape have been focus on the generation of the curvature and less attention has been put on the mechanism of curvature sensing. Thus, this fascinating subject...

injection molding is one of the most common processes which are used for manufacturing different plastic parts. this method includes 3 continuous steps: filling of the mold, cooling and driving the part out. a wide range of plastic and non-plastic materials can be used as raw material in this process. one of the most important advantages of this way of production is that it is very economic. in...

Objectives: The packing of goods in any industry is a tedious work. The proposed system evaluates the optimal packing and prediction of 3D bin packing maximize the maximize profit. Methods/Statistical Analysis: The Adaptive Genetic Algorithm (AGA) is used to solve the 3D single bin packing problem by getting the user input data such as number of bins, its size, shape, weight, and constraints if...

Brass Ferrules have been used as packing in a laboratory- scale glass distillation column approaching pilot plant size because of their availability in all sizes and low cost. The available size range is such that these ferrules could also be used in industry and the results of this study could be scaled up. The performance of the new packing has been compared with the performance of glass ...

This work presents a method (CDOM) for optimizing multiple system level assembly characteristics of complex mechanical assemblies by placement of their components. It addresses any component shape (including non-convex, hollow, sharp edges) connected together by functional constraints. This method finds multiple solutions to the Engineering Configuration Design Problem (ECDP) and proposes a sim...
