While the study of psychology has offered little in the way of explaining the creative process, Koestler examines the idea that we are at our most creative when rational thought is suspended--for example, in dreams and trancelike states. All who read The Act of Creation will find it a compelling and illuminating book.

Stereolithography is a solid freeform technique (SFF) that was introduced in the late 1980s Although many other techniques have been developed since then, stereolithography remains one of the most powerful and versatile of all SFF techniques It has the highest fabrication accuracy and an increasing number of materials that can be processed is becoming available In this paper we discuss the characteristic features of the stereolithography technique and compare it to other SFF techniques The biomedical applications of stereolithography are reviewed, as well as the biodegradable resin materials that have been developed for use with stereolithography Finally, an overview of the application of stereolithography in preparing porous structures for tissue engineering is given

A review on stereolithography and its applications in biomedical engineering

A first aspect of the invention relates to an epoxy resin coating used in reflection photoelasticity, which is "black" in the infra-red part of the spectrum; another aspect to the use of an epoxy resin as a coating on at least one surface of a body to be subjected to cyclic loading and examined by thermoelasticity, and another aspect to a method of making thermoelastic measurements of a body when subjected to cyclic loading and hence measurements of stresses or strains, comprising, as an initial step, coating the surface(s) of the body to be measured with an epoxy resin whereby the surface(s) so coated represents a black body

Coating for thermoelasticity

Both physical and virtual prototyping are core elements of the design and engineering process. In this paper, we present an industrial case-study in conjunction with a collaborative agile design engineering process and “methodology.” Four groups of heterogeneous Post-doc and Ph.D. students from various domains were assembled and instructed to fulfill a multi-disciplinary design task based on a real-world industry use-case. We present findings, evaluation, and results of this study.

Virtual and mixed prototyping techniques and technologies for consumer product design within a blended learning design environment

A complete definition of stresses requires an evaluation of the magnitude and directions of the components of stress related to a co-ordinate system. The combination of thermoelasticity and photoelasticity offers the potential to achieve this objective since photoelasticity provides the direction of principal stresses and difference in magnitude, whilst thermoelasticity yields the sum of the magnitude. Recent experiments have shown that simultaneous measurements can be made. The demands of simultaneous measurement for a full-field of view imply that all the photoelastic information must be captured quickly. A hybrid technique based on spectral contents analysis and phase stepping has been developed. The methodology and instrumentation for combining the automated photoelasticity with thermoelasticity has been developed In conclusion, it is shown that the complete state of stress over an area of the surface of the component can be evaluated without any prior knowledge of the stress state.

Automated Photoelasticity Applied With Thermoelasticity to Real Components

The development of extremely high performance aerospace power transmissions will be a very interesting technological challenge for the next future. In gear design for high power transmission, desirable characteristics, such as low noise emissions, low vibrations, minimum size, minimum maintenance cost, but most of all minimum weight can be obtained through the development of innovative layouts. However, most of the rules based on experimental data, by which common gearns are calculated and verified, are not applicable to transmissions whcih can be defined unconventional in terms of geometry and/or operation conditions (high power, high rotating speed, low weight). In these cases, numerical simulations can be performed bu using FEM codes. The objective of this work is to describe how interated CAD/FEM tools can be employed to develop procedures for the static performance analysis of unconventional gears. In the paper, potential characteristics, limits and capabilities of simulating real system behaviours are discussed.
