A method of analysis is developed for two dimensional flow on general surfaces of revolution in turbomachines with arbitrary blade shapes. The method of analysis is developed for steady, compressible, nonviscous, irrotational flow that is assumed uniform normal to the surfaces of revolution. Incompressible solutions on a mean surface of revolution between the hub and shroud are presented for four rates through each of two centrifugal impellers with the same hub-shroud contours but with different blade spacings. In addition, correlation equations are developed whereby the velocity components and the stream function distribution can be predicted for compressible or incompressible flow in straight-blade impellers only, with any tip speed, flow rate, area variation, blade spacing, and for any flow surface of revolution.

This book contains articles in several areas involving a dominant role of surfaces and interfaces. It is divided into four sections. The first section deals with theoretical and experimental aspects of the structure and morphology of clean surfaces and adsorbed layers on surfaces. The next section concerns growth on surfaces leading to semiconductor devices with quantum well, quantum wire and quantum dot structures; also deals with spin transport in 2DEG. Section 3 is on layered synthetic microstructures (LSMs). Analysis of interface roughness and layer composition of LSMs by X-ray techniques, fabrication of hard X-ray telescopes with LSMs, and diffusion across interfaces of LSMs are discussed here. The last section contains articles dealing with semiconductor surfaces exposed to ion beams and ion-irradiated semiconductor multilayers.

This exhibition of twenty-five painters celebrates the remarkable creative talents that have contributed much to Chicago's vital cultural life. Moreover, the exhibition introduces the works of younger Chicago artists who continue to reinforce the artistic excellence with which the city, its collectors, and its institutions are identified.

Human beings are surrounded by surfaces: from our skin to faces, to the walls and streets of our homes and cities, to the images, books, and screens of our cultures and civilizations, to the natural world and what we imagine beyond. In this thought-provoking and richly textured book, Joseph A. Amato traces the human relationship with surfaces from the deep history of human evolution, which unfolded across millennia, up to the contemporary world. Fusing his work on Dust and On Foot, he shows how, in the last two centuries, our understanding, creation, control, and manipulation of surfaces has become truly revolutionary--in both scale and volume. With the sweep of grand history matched to existential concerns for the present, he suggests that we have become the surfaces we have made, mastered, and now control, invent, design, and encapsulate our lives. This deeply informed and original narrative, which joins history and anthropology and suggests new routes for epistemology and aesthetics, argues that surfaces are far more than superficial façades of deep inner worlds.

ESPRIT Project 322, "CAD Interfaces", has been established to define the most important interfaces in CAD/CAM systems for data exchange, data base, finite element analysis, experimental analysis, and advanced modeling. The definitions of these interfaces are being elaborated in harmony with international standardization efforts in this field. One principal goal of the project is to develop techniques for the exchange of CAD information between CAD systems, and from the CAD domain to CAA (Computer Aided Analysis) and CAM (Computer Aided Manufacturing). This volume presents a proposal for a neutral file format for CAD data: curves, surfaces, and solids. The specification is based on a reference schema for CAD data bases and is defined informally with respect to its semantics and formally with respect to its syntax. This volume is a revised edition of "Specification of a CAD*I Neutral File for Solids" Version 3.2. The revision reflects the enhancements which result from the implementation of communication processors in eight different CAD systems and from the practical exchange of solid models between these systems. Due to the close interaction between the CAD*I project and the coming-up international standard STEP this specification also serves as an introduction to the geometry model that will
