Community engineering

As for radiography it seems that the lack of attention is due to a combination of trends and fashion, coupled to a general unawareness of this technique amongst the civil engineering community. 

The simplest case of fluid modeling is the technique known as computational fluid dynamics. These calculations model the fluid as a continuum that has various properties of viscosity, Reynolds number, and so on. The flow of that fluid is then modeled by using numerical techniques, such as a finite element calculation, to determine the properties of the system as predicted by the Navier-Stokes equation. These techniques are generally the realm of the engineering community and will not be discussed further here. 

Conventional filtration theory has been challenged a two-phase theory has been appHed to filtration and used to explain the deviations from paraboHc behavior in the initial stages of the filtration process (10). This new theory incorporates the medium as an integral part of the process and shows that the interaction of the cake particles with the medium controls filterabiHty. It defines a cake-septum permeabiHty which then appears in the slope of the conventional plots instead of the cake resistance. This theory, which merely represents a new way of interpreting test data rather than a new method of siting or scaling filters, is not yet accepted by the engineering community. 

The present book brings to the reader a state-of-the-art treatment of high-pressure shock compression of solids in a type of tutorial manner. It has been felt by the shock physics and engineering communities that there is a need for such a book to aid the education and training of undergraduate and graduate students of physics and engineering. We hope that the present book will partially fill that vacuum. We certainly welcome any comment or criticism on the content of this book, in the hope that these will be incorporated into later editions of the book. 

Designing for robustness has also been associated with the DFM guidelines (Russell and Taylor, 1995). Robust design has different meanings to different engineering communities. For example, the three descriptions below focus on three different but connected aspects of product design ... 

The Corrective Measures Study (CMS) elements as outlined in the EPA document entitled RCRA Corrective Action Plan - Interim Final (U.S.EPA, 1988) provides guidance to the regulatory community on the steps practiced by the engineering community in the conduct of a feasibility study. These steps include ...

Continual disappointment in his business affairs kept him in relative obscurity even as his developments were reshaping the industrial world. Today, even the engineering community rarely notes his successes as the inventor of the first self-propelled... 

Architects and builders desire factual data on products. However, their standards or codes in many cases only identify the composition of the end item, with no performance data. In most cases, the plastics were never subjected to engineering analysis but approved based on past performances. This situation is not new to the engineering community, where patience, time and/or money resolve the problem.

The impetus for this volume came from the symposium, and many of the presentations from that symposium are represented here as chapters or parts of chapters. To broaden the scope of this volume, other individuals were invited to contribute chapters relating to their own topic of interest. Our chief objective is to provide, for chemists, materials scien-tists/technologists, and the science and engineering community in general, an overview of this emerging new subdiscipline of chemistry. 

There are already many books published on the subjects of fluidization, solids handling, and processing. On first thought, I was skeptical about the wisdom and necessity of one more book on these subjects. On closer examination, however, I found that some industrially important subjects were either not covered in those books or were skimpily rendered. It would be a good service to the profession and the engineering community to assemble all these topics in one volume. In this book, I have invited recognized experts in their respective areas to provide a detailed treatment... 

All of the areas of research discussed in this chapter will require interdisciplinary collaborations among chemists, engineers, biologists, physicists, and materials scientists. This critical area of national need should be the catalyst for breaking down disciplinary barriers and promoting interaction among scientific and engineering communities.
