PURPOSE To experimentally validate a non-linear finite element analysis (FEA) modeling approach assessing in-vitro fracture risk at the proximal femur and to transfer the method to standard in-vivo multi-detector computed tomography (MDCT) data of the hip aiming to predict additional hip fracture risk in subjects with and without osteoporosis associated vertebral fractures using bone mineral de...

Functional Gene Networks (FGNet) is an R/Bioconductor package that generates gene networks derived from the results of functional enrichment analysis (FEA) and annotation clustering. The sets of genes enriched with specific biological terms (obtained from a FEA platform) are transformed into a network by establishing links between genes based on common functional annotations and common clusters...

In order to efficiently encrypt multimedia streams delivered in real-time environments, a Fast Encryption Algorithm for Multimedia (FEA-M) was proposed [8, 9]. Cryptanalyses of this technique [1, 3, 4, 5] have identified its weaknesses and an improved variant has been suggested in [5]. In this paper, we identify further weaknesses in the original FEA-M and also in the improved variant. Our solu...

A way to manage the information needed during the FE simulation model preparation is by means of attributes linked to the adopted models. This paper presents the design and implementation of an attribute management system that supports the representation of all the information and data related to the simulation domain definition, needed to qualify an engineering analysis. The main objective of ...

This paper describes a modular framework that facilitates the development of finite element analysis (FEA) programs. The framework allows users easy access to the FEA program and the analysis results by using a web-browser or other application programs, such as MATLAB. In addition, the framework enables new as well as legacy codes to be incorporated from disparate sites in a dynamic and distrib...

This special issue of The Anatomical Record presents a series of papers that apply the method of finite element analysis (FEA) to questions in vertebrate biomechanics. These papers are salient examples of the use of FEA to test hypotheses regarding structure-function relationships in complexly shaped biological objects such as skulls and in areas of the skeleton that are otherwise impervious to...

In order to improve the performance of a magnetically levitated (maglev) axial flow blood pump, three-dimensional (3-D) finite element analysis (FEA) was used to optimize the design of a hybrid magnetic bearing (HMB). Radial, axial, and current stiffness of multiple design variations of the HMB were calculated using a 3-D FEA package and verified by experimental results. As compared with the or...

This paper deals with characteristics of interior permanent magnet synchronous motor considering anisotropic characteristics of electrical steel sheets. Motor characteristics of back electro-motive force (EMF), d-q axis inductances, and core loss are calculated by FEA considering anisotropy of electrical steel sheets and compared to the results from experiment and general FEA; using single mate...

This paper shows the details of comparison of noise attenuation level by convergent and divergent cylindrical duct with space constraints by using Transmission loss parameter. Reactive muffler is noise reduction element on exhaust system. Two basic term is used for noise attenuation first is transmission loss (TL) and other is insertion loss (IL). The main aim of this paper is to use of TMM, FE...

Fracture of femur bones in car accident is common. In the present work, the fracture of femur bone was modeled as a failure under three-point bending. The CT scan data was converted into 3D solid modeling using Mimics software. The finite element analysis (FEA) was carried out using ANSYS software. The FEA results were in good agreement with the experiment results.
