This book is the second of two volumes that present the main results which emerged from the project CIP - "C"omputer-Aided, "I"ntuition-Guided "P"rogramming - at the Technical University of Munich. Its central theme is program development by transformation, a methodology which is becoming more and more important. Whereas Volume I contains the description and formal specification of a wide spectrum language CIP-L particularly tailored to the needs of transformational programming, Volume II serves a double purpose: First, it describes a system, called CIP-S, that is to assist a programmer in the method of transformational programming. Second, it gives a non-toy example for this very method, since it contains a formal specification of the system core and transformational developments for the more interesting system routines. Based on a formal calculus of program transformations, the informal requirements for the system are stated. Then the system core is formally specified using the algebraic data types and the pre-algorithmic logical constructs of the wide spectrum language CIP-L. It is demonstrated how executable, procedural level programs can be developed from this specification according to formal rules. The extensive collection of these rules is also contained in the book; it can be used as the basis for further developments using this method. Since the system has been designed in such a way that it is parameterized with the concrete programming language to be transformed, the book also contains a guide how to actualize this parameter; the proceeding is exemplified with a small subset of CIP-L.

herrschen. Bedeutsam ist auch die Abgrenzung der dritten Ebene, der Ebene der verselb- standigten Variablen und Zeiger. Der vergleichsweise geringe Umfang von Kap. 7 bedeutet einerseits, dass die Beschreibung sich auf Grundsatzliches beschrankt, dem sich viele aus der Literatur der Systemprogrammierung bekannte Einzelheiten unterordnen, beispiels- weise aus D. E. Knuth's, The Art of Computer Programming' oder G. Seegmullers, Ein- fuhrung in die Systemprogrammierung', andererseits aber auch, dass die Vervollstandi- gung der theoretischen Grundlagen noch aussteht. Zu den einzelnen Abschnitten dieses Buches gibt es einen Hintergrund unterschiedlich weit entwickelter mathematischer Theorien. Wichtige Grundbegriffe sind verbandstheore- tischer Natur. Die fundamentalen Arbeiten von D. Scott haben das eindrucksvoll bewie- sen. Bei den Rechenstrukturen des 3. Kapitels steht die moderne Theorie der universellen Algebra im Hintergrund, insbesondere Arbeiten von Birkhoff und Tarski sind hier von Be- deutung. Da wir kein mathematisches Lehrbuch vorlegen, mussen wir uns meistens mit Andeutungen und Hinweisen begnugen. Das Buch hat sich aus Vorlesungen und begleitenden UEbungen entwickelt, die in den letz- ten Jahren an der Technischen Universitat Munchen gehalten wurden. Es entstand in enger Wechselwirkung mit dem Projekt CIP ("Computer-aided Intuition-guided Programming") und dem Teilprojekt "Breitbandsprache und Programmtransformation" im Sonderfor- schungsbereich 49, Programmiertechnik, an der Technischen Universitat Munchen. Bei dem Versuch, fur ein einigermassen abgerundetes, geschlossenes Lehrgebaude der Programmie- rung die Fundamente zu legen, musste vieles fragmentarisch bleiben. In manchen Punkten war es notwendig, Positionen zu beziehen, die auf den ersten Blick unkonventionell erschei- nen moegen, um Erstarrungen zu loesen und einseitige Doktrinen zu korrigieren.

This text is a complete resource for all the imaging technologies, not just plain film radiography. It provides introductory material on pharmacological nomenclature, drug classifications, pharmacokinetics, and drugs used in imaging. It also offers comprehensive coverage of diagnostic contrast agents, along with drug administration procedures, emergency responses to drug reactions, and legal and ethical aspects of medication administration. Objectives and Key Terms open each chapter. Learning exercises include true/false, fill-in-the-blank, multiple-choice, and short-answer questions at the end of each chapter, with answers at the end of the book. Did You Know? boxes offer interesting tidbits of historical or current pharmacology information, connecting the book's drug content to everyday situations. Clinical Alert icons point out possible adverse reactions and toxic effects. Discussion of pharmacodynamics and drug classifications focuses on radiopaque contrast media used in imaging procedures, using clearly written text and useful tables. Pharmacokinetics coverage describes how drugs are absorbed, metabolized, distributed, and eliminated. Complete coverage of emergency procedures in response to adverse reactions to contrast media includes crash cart procedures and drugs used to treat cardiac and/or respiratory arrest and how to administer them appropriately. Updates on all contrast agents. New information on the use of contrast agents in ultrasound. New Drug Classifications chapter. New chapter on drug-related emergencies includes case studies. Evolve Resources for instructors include a 220-question test bank and an electronic image collection.
