Bone resorption around hip stems, in particular periprosthetic bone loss, is a common observation post-operatively. A number of factors influence the amount of bone loss over time and the mechanical environment following total hip replacement (THR) is important. Conventional long stem prostheses have been shown to transfer loads distally, resulting in bone loss of the proximal femur. More ...

As embalagens de produtos alimentícios são hoje em dia predominantemente feitas com cartão tipo LPB (Liquid Packaging Board) e usualmente estocadas de forma empilhada, tanto nas prateleiras como nos depósitos dos supermercados. O LPB é um compósito multicamadas de construção complexa, envolvendo, tipicamente, papel produzido com fibras virgens, polietileno e alumínio. O alimento líquido ...

The Automotive industry has now become a technology of “Drive by Wire”. This technology is used to replace the conventional mechanical system by electromechanical system which is able to perform the same tasks faster, more reliably and accurately. The problems with the traditional braking systems are unreliable at high speeds, long respond time, more brake pad wear, high temperature ...

Developers of numerical models who address the title problem face several hurdles, such as: (1), the need to formulate boundary conditions applicable in an unbounded region; (2), The need to specify conditions suitable to ensure a unique solution in a doubly connected region; and (3), The need to allow the interior boundary to have a sharp edge, such as a cusp. The aim of the work reported ...

The Swedish Nuclear Fuel and Waste Management Co (SKB) is responsible for final disposal of spent fuel and radioactive waste. SKB operates SFR, an underground waste repository in crystalline rock. The evolution of groundwater flow within the repository needs to be estimated considering different options for the design of the engineered barriers. The goal is to predict the effects of flow and ...

The paper demonstrates that for some models a 2D geometry in Cartesian coordinates can be used to obtain a 3D solution with changes in z-direction. A heat exchanger serves as an example of a practical application. The required flow rate in a straight cooling pipe penetrating perpendicularly into a warm wall is calculated to keep the wall temperature below a given limit. Cold water pumped into the ...

In order to predict, improve and meet a certain set of performance requirements related to the indoor climate of buildings and the associated energy demand, building energy simulation (BES) tools are indispensable. Due to the rapid development of FEM software and the Multiphysics approaches, it should possible to build and simulate full 3D models of buildings regarding the energy demand. The ...

The U.S. Naval Academy has used COMSOL as a research tool for many years. Academic usage of COMSOL for student use has only begun in the last five years. Student involvement comes in four types, course-wide usage, focused course related work, student projects and semester-long research projects. A summary of how COMSOL has been successfully used at USNA will be given, showing examples of ...

This work concerns the development of a new direct parameter identification procedure for a class of nonlinear reaction- diffusion equations. We assume to know the model equations with the exception of a set of constant parameters, such as diffusivity or reaction term parameters. Using the Finite Element Method we are able to transform the original partial differential equation into a set of ...
