To achieve a new method for predicting the result of disc replacement or to predict biomechanics of lumbar (or any other skeletal segment) by finite element model analysis, its necessary to follow an organized procedure including 3D bone model, meshing the proposed model, designing an artificial implant and simulation of loading condition. In this study we try to explain the whole procedure step by step from importing the CT image to analysis of lumbar section with designed implant. First it's explained how the 3D model can be made based on the CT image using MIMICS software and some details...

In this book a new design of insect bioinspired robot has been proposed. The main focus of this research is to analyze the stability of insect robot in different motion pattern through studying the center of gravity variations. The basic design has been done by CATIA software based on the biological model of Arthropods. A hydraulic three segmented model has been used for modeling each jointed legs and the three dimensions of ball and hinged joint has been used for increasing the degree of freedom for the robotic system. Various random gait patterns have been used for modeling an insect...
