ABSTXACT This paper describes the study of the possibility of x-ray stress measurement in which stresses are obtained by analyzing the whole of one diffraction ring detected with a two-dimensional x-ray detector called an imaging plate (IP). The theory of the stress determination proposed by Taira et al (1978) was shown and advanced to make measurable all plane stress components. The experiment...

Two canonical representations for regularization of unit sphere functions encountered in the context of high angular resolution diffusion imaging (HARDI) are discussed. One of these is based on spherical harmonic decomposition, and its one-parameter extension via Tikhonov regularization. This case is well-established, and is mainly reviewed for the sake of completeness. The second one is new, a...

Imperfections in the spotlight: fluorescence microscopy was used to detect defects in metal-organic frameworks formed during synthesis. In contrast to currently available techniques, confocal fluorescence microscopy offers the advantage of three-dimensional imaging at the single-crystal level combined with the sensitivity required to study the start of defect formation.

3D printing is a form of rapid prototyping technology, which has led to innovative new applications in biomedicine. It facilitates the production of highly accurate three dimensional objects from substrate materials. The inherent accuracy and other properties of 3D printing have allowed it to have exciting applications in anatomy education and surgery, with the specialty of neurosurgery having ...

This paper presents a model of a virtual laboratory for an introductory computer science course. The proposed model aims at solving a number of problems involved in the educational procedure of such a course. The model architecture consists of seven modules, each one corresponds to a specific topic of the course. Every module provides several different services in order to assist students to as...

Empirical studies concerning face recognition suggest that faces may be stored in memory by a few canonical representations. In cortical area V1 exist double-opponent colour blobs, also simple, complex and end-stopped cells which provide input for a multiscale line/edge representation, keypoints for dynamic routing and saliency maps for Focus-of-Attention. All these combined allow us to segrega...
