Stress Analysis of the Human Ligamentous Lumber Spine-From Computer-Assisted Tomography to Finite Element Analysis

Detailed investigation on biomechanics of a complex structure such as the human lumbar spine requires the use of advanced computer-based technique for both the geometrical reconstruction and the stress analysis. In the present study, the computer-assisted tomography (CAT) and finite element method (FEM) are merged to perform detailed three dimensional nonlinear analysis of the human ligamentous...

Groups assembled from free and direct products

Let A be the collection of groups which can be assembled from infinite cyclic groups using the binary operations free and direct product. These groups can be described in several ways by graphs. The group (Z ∗Z)×(Z ∗Z) has been shown by [1] to have a rich subgroup structure. In this article we examine subgroups of A–groups. DefineA to be the smallest class of groups which contains the infinite ...

The Micro-Rato contest: a popular approach to improve self-study in electronics and computer science

Robotic competitions for students have been around for more than two decades. Although the benefits of these competitions can be exploited at various levels of education, recent examples have been following a trend towards higher complexity. In order to bring the pedagogical advantages of robotics competitions down to a level where they can be exploited by undergraduate and high school students...

Self-Assembled Nanodielectrics (SANDs) for Unconventional Electronics

The field of unconventional electronics represents a new opportunity for the semiconductor and electronics industries.1 This broad field encompasses both “printed organic/inorganic” and “transparent” electronics. The first technology aims at the fabrication of extremely cheap electronic devices such rf-id tags, ‘smart’ cards, flexible electronic paper, and backplane circuitry for active matrix ...
