Book excerpt: 0.1 Gaps in Optimizing A comparison of the levels of development of Operations Research, Simulation Technique and Optimal Control Theory appears to gain increasing interest. Operations Research Sciences achieved very high mathematical standards and solved a great amount of important optimization problems, mainly at the level of management of private corporation and civil or military government tasks, however, these achievements are seldom incorporated in the mathematical curriculum of modern universities. Nevertheless, Operations Research seems to have failed in solving long range or strategical problems as they arise in any broader social, economical or political context (MUller-Merbach, 1976). Also for the weakest task, namely that of improving theory building, system simulation works as an optimization tool. Simulation models of large complex systems, like socio economical or political ones, failed until now to fit large empirical data bases. This was, in fact, one of the few serious objections against the form in which Forrester solved some problems modelling and simulating urban and world de velopments (Forrester, 1969; Forrester, 1971; IEEE-SCC October 197o; IEEE-SMC April 1972; Mass, 1974; Schroeder, 1975).

Available in PDF, EPUB and Kindle. Book excerpt: This book is a presentation of my recent research work into the theory and applications of mathematical relations between finite sets. The consequent results and concepts are expressed in 'conjunction' with the idea of a union of simplicial complexes and the algorithms and overall methodology have become known as Q-Analysis. The mathematical ideas are essentially comhinatorial and are developed in Section-A of the book, whilst Section-R contains an application to a community study (that of the IJniversity of Rssex). All of the work has been published elsewhere, in the usual form of papers, and a comprehensive introduction to the whole approach will be found in my earlier book, Mathematical Structure in Human Affairs (Heinemann, London 1974). Much of the research work referred to in this present hook would not have been possible without the co-operation of my research team, of whom I would particularly like to thank J.II. Johnson, and its puhlication owes a lot to the secretarial help provided by ~Iary Low. R.H. Atkin IJniversity of Rssex U.K.

Available in PDF, EPUB and Kindle. Book excerpt: 1.1 Statement of the Problem This work describes a new and effective computer algorithm for detecting the contours of ribs in ehest radiographs. The problem, which is common to both the research areas of Machine Vision and Biomedical Computing, is to extract graphical information, such as that represented in Figure 1-lb, from a picture such as Figure 1-la. Figure 1-la shows a typical posterior-anterior (PA) ehest radiograph while Figure 1-lb shows a drawing of the ventral aspect of the thorax. lt is hoped that this researchwill contribute significantly toward developing an automated system for interpreting ehest radio graphs. 1.2 Why Have We Carried Out This Research? Since about one-third of the 650,000,000 medical radiographs (X-ray photographs) taken annually in the United States areehest radiographs, there is a growing awareness of the need for a computer aided system to help diagnose these radiographs. The detection of rib contours is, of course, a necessary element in such a system. In addition to being able to accommodate the need for a mass screening program, an automated systemalso has the ability to detect anomalies at earlier stages. Ziskin et al (1971) state that reliable 2 {a) Original Chest Radiograph Figure 1-1.

We are grateful to Hayward Alker, Jr. and William H. Riker of the MSSB for their help and encouragement. The graph shown on the cover is a cognitive map representation of the output from our computer simulation of foreign pOlicy decision-making. We would like to thank Robert Axelrod and Gary Raffel of the University of Michigan for generating the graph. PART I INTRODUCTION 1 CHAPTER 1 THOUGHT AND ACTION IN FOREIGN POLICY G. MATTHEW BONHAM The American University MICHAEL J. SHAPIRO University of Hawaii Introduction The papers assembled here constitute, and to some extent represent, widely disparate views of foreign policy thinking and decision-making. As is the case with almost any collective enterprise, it is possible to suggest some noteworthy resemblances among the contributions to this volume and to indicate grounds for distinguishing them from other "approaches.
Download or read book Computer recognition of human faces written by KANADE and published by Birkhäuser. This book was released on 2013-12-01 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Picture processing by computer has found its application in various fields. Character recognition has shown the most practical success. Furthermore, the techniques span much more sophisticated applications such as interpretation of biomedical images and X-ray films, measurement of images in nuclear physics, processing of a large volume of pictorial data sent from the satellites, etc. The particular problem attacked in this thesis is computer analysis and identification of human faces. Pictures of human faces are successfully analyzed by a computer program which extracts face feature points, such as nose, mouth, eyes, and so on. The program was tested with more than 800 photographs The research has been done with main emphasis on the method of how to incorporate the picture structures into the picture anlysis program. The success of the program is due to the employment of a flexible picture analysis scheme with feedbacks, which will be described in the next chapter. An experiment on face identification of 20 people was also conducted. I-1. Picture Analysis and Recognition- New Aspects When shown the pictures of the human face of Fig. 1-1, we can immediately tell the positions of the nose, mouth and eyes; and more- over, we can say that both pictures surely portray the same person. Picture analysis and recognition by computer concerns itself with this type of two-dimensional image processing. In this thesis, I selected human-face pictures as objects of processing.

Available in PDF, EPUB and Kindle. Book excerpt: Technological progress is a major factor chaping economic growth. Today's standard of living is a direct result of scientific advances and technical change in the past. Since uncontrolled technological progress has become amenace to our well being and may actually threat our survival, it is necessary to learn to manage technological progress and direct innovative activities in such a manner that both private wants and social needs playa dominant role in determining the rate and direction of technical change. This requires a better understanding of the processes of technical change, of their impact on and interrelationships with economic and social developments and of the means and measures by which both individuals and governments can influence and direct technological progress. To this end, the Ninistry for Research and Technology of the Federal Republ ic of Germany and the National Science Foundation of the Uni ted States of America invited a group of scholars, corporate managers and civil servants to a one week seminar on "Technolo gical Innovation". The seminar took place in April, 1976, in Bonn, Federal Republ ic of Germany. Most papers presented at this meeting were specifically prepared for the seminar. With this volume, they are made available to a larger audience to further stimulate discussion not only among scholars interested in innovation research and technology policy questions but also among managers, union officials, civil ser vants and others directly or indirectly concerned with and affected by technical change.

Available in PDF, EPUB and Kindle. Book excerpt: The role of the computer in the practice of organic chemistry has been firmly established over the past decade. Its uses as a large scale information storage and retrieval device in chemistry have been too numerous to mention. More recently, the applicability of computers to the problem of discovering valid and reasonable synthesis routes for organic molecules has been demonstrated. This has been both as an adjunct to the 1 chemist in the on-line interactive mode ,2,3 and also as a wholly computer-directed system seeking to simulate the intelligent prob- 4 lem-solving activity of the human organic synthetic chemist. ,5 In all of these computer applications to organic chemistry, it has been necessary to devise some computer-compatible repres- tation of an organic molecule that is both canonical and c- venient for table look-ups. This is in order that entities that have been constructed at different times under different circumstances can be identified and classified, with identical molecules being recognized as such even if their connection matrices list the elements of the molecule in different orders.

Book excerpt: Transformations: Mathematical Approaches to Culture Change focuses on the application of contemporary mathematical techniques to the study of culture change and formulates problems in archaeology, anthropology, and historiography in such a way that they are susceptible to treatment of a mathematical kind. Mathematical models, extending from the almost purely quantitative methods of physics to the purely verbal conceptual explanations, are described. Emphasis is placed on catastrophe theoretic models that exemplify the use of soft mathematics in situations in which the use of hard quantitative models is not possible. Comprised of 21 chapters, this book begins with an overview of the role of mathematics in theoretical archaeology, followed by a discussion on two general categories of mathematical methods that seem to be suitable for modeling cultural transformations: methods of dynamical systems theory and methods that give greater emphasis on discrete entities and the structural relations or patterns among them. Subsequent chapters deal with the use of mathematics in history; morphogenesis in biological and social systems; simulation of the growth of hierarchies; and logistic trends in Southwest population growth. A reconstruction of political units in the Valley of Mexico during the Toltec period is also presented. This monograph will be of interest to archaeologists, anthropologists, historians, biologists, sociologists, and mathematicians.
