Heat Transfer Enhancement Of Heat Exchangers

The information and accuracy obtained by whatever imaging methodology is a complex result of a multidisciplinary effort of several sciences such as Physics, Engineering, Electronics, Chemistry, Medicine, etc .. Development has occurred through work performed in different environments such as basic and applied research laboratories, industries and clinical centers, with the aim of achieving an efficient transfer of know-how and technology for the improvement of both investigation possibilities and health care.

Electromagnetic Modelling and Measurements for Analysis and Synthesis Problems In this volume is presented the proceedings of a NATO Advanced Study Institute (ASI) on the theme of Electromagnetic Modelling and Measurements for Analysis and Synthesis Problems. It has been my good fortune to act as co-director of two of Jozef's previous ASIs, and so I am well acquainted with the JKS format for ASIs. A further dificulty has arisen through the untimely death of Jozef's former deputy and colleague at GEC Research, Ed Pacello, who assisted Jozef with the organisation of the precursor of this ASI.

Persons in many disciplines are studying various aspects of Greek and Roman marble usage. Yet, quarry sources changed in time as preferences for different marbles were influenced by local traditions, the pos­ sibilities of transport, esthetic tastes, and economics. Classical Marble: Geochemistry, Technology, Trade Beginning in the Bronze Age sculptu­ re began in marble and throughout classical times the most im­ portant statues, reliefs, monuments and inscriptions were made of it. Geologists and geochemists are working on methods to determine the provenance of marble; ar­ chaeologists are noting changing patterns of import and use in excavation~ and discovering how improving quarrying techniques and prelimihary dressing of the extracted material influenced the final shape of artifacts; ancient historians are now under­ standing quarry organization and bureaucracies that controlled marble production and trade; art historians are seeing how phy­ sical characteristics of the stone affected the techniques and style of sculpture; architects and engineers are interested in quarry technologies and usage in building construction.

This yielded a number of professional meetings, where day-to-day research activities are presented.

This fact was first reported in the pioneering work of Prof. Hegner on the solid-state polymerization of disub­ stituted diacetylenes in the late 1960s.

.This book provides invaluable information for such purposes. Heat transfer enhancement in single-phase and two-phase flow heat exchangers in important in such industrial applications as power generating plant, process and chemical industry, heating, ventilation, air conditioning and refrigeration systems, and the cooling of electronic equipment. Energy savings are of primary importance in the design of such systems, leading to more efficient, environmentally friendly devices.

The Scientific Affai rs Divi sion of the North Atl antic Treaty Organization sup­ ported the conference as part of their program of Advanced Research Workshops, and the Science and Technology to Aid the Handicapped Program of the National Science Foundation provided additional major financial support. Our goal was to engage these groups in discussion with one another about prospects for the future of electronic spatial sensing, in the light of emerging technologies and the increasing sophistica­ tion of behavioral research related to this field. During September 10-14, 1984, we held a Research Workshop at the Lake Arrowhead Conference Center, California, bringing togeth­ er leaders in the field of electronic spatial sensors for the blind from the psychology, engineering, and rehabilitation areas.

Electronic Spatial Sensing for the Blind. Broader overvi ews are provi ded in the paper by Brabyn, and in our Historical Overview, Final Commentary and the Introductions to each section. The Center for Social and Behavioral Sciences Research of the University of California, Riverside provided financial as well as major logistical support.
