The argumentation services platform with integrated components (Aspic) project aims to provide advanced argumentation-based computational capabilities. Argumentation is a potentially important paradigm for developing commercial and public services that are flexible and easily understood by human users.
In the real life, the leg and its skeleton are exposed at the most diverse stresses. It is known that the human bone is one of the most important natural composite materials. The paper presents a method of study and the steps to obtain the virtual bones of the human body, method applied to tibia bone. For that purpose was used a CAD parametric software(More)
INTRODUCTION Osteoporosis is a common affection characterized by a reduction of bone mass that affects mostly women after menopause. It currently leads to fractures, especially of the spine and hip thus enhancing the costs of medical care. There are many factors that contribute to its development, leading to various strategy lines to deal with it. AIM The(More)
Aseptic osteonecrosis causes various clinical manifestations, depending on its location, but has in common a histopathological and radiological substrate. Aseptic osteonecrosis of the femoral head is a condition whose pathogenesis remains unclear despite many theories developed so far, and the discovery of numerous risk factors. The objective of this study(More)
In this paper, we present a three-dimensional mathematical model for a normal hip joint. The three-dimensional finite element model has been constructed based on Computer Tomograph scans of the bones. The obtained 3D model is studied using the finite element method, taking into consideration the real structure of the bone and the mechanical characteristics(More)
The paper presents a method of study and the steps to obtain the virtual tibial component of the human knee joint prosthesis. For that purpose CAD parametric software was used which allows the construction of a high definition model. The obtained 3D model was studied using the finite element method and the stress and displacements distribution was obtained(More)
UNLABELLED The avascular necrosis of the femoral head is an illness induced by the cutoff of blood flow to the femoral head and it affects mostly young adults between the ages of 30 and 50 years, raising therapeutic and diagnostic issues. Many risk factors are incriminated in the development of avascular necrosis of the femoral head like: trauma, chronic(More)
One-dimensional nonlinear lattices with harmonic long range interaction potentials (LRIP) of inverse power type are studied. For the nearest neighbour nonlinear interaction we shall consider the anharmonic potential of the Fermi-Pasta-Ulam problem and the φ+φ as well. The continuum limit is obtained following the method used by Ishimori [1], and several(More)
