Nuclear ftedicine is not and has not been a purely imaging discipline. It is function analysis that has always been the focal pOint. This fact has become particularly obvious in the last few years through the employment of nev short-lived radionuclides, new technical procedures and data processing. The disadvantage of function analysis in Inclear ftedicine through the use of radioactively labeled compounds is that more and more complicated and expensive equipment his to be used. A further characteristic is that these machines are stationary, and that the patients cannot be examined under physiological conditions. For technical reasons the x-camera is developing in the direction of mea suring...

Der Studien- und Forschungsführer Informatik, der in Zusammenarbeit mit der Gesellschaft für Informatik herausgegeben wird, liegt jetzt in der zweiten neubearbeiteten Auflage vor. Er gibt zunächst eine Einführung in das Fachgebiet Informatik und in die Gestaltung des Informatikstudiums an den deutschen Universitäten und Fachhochschulen. Sowohl die detaillierte Übersicht über die Studienpläne an den einzelnen Hochschulen als auch die Hinweise auf Informatik-Forschungsprojekte an Universitäten und Fachhochschulen wurden aktualisiert und erweitert. Auch Forschungsprojekte an außer-universitären Forschungszentren werden beschrieben. Neu aufgenommen wurden die Studienmöglichkeiten fü...
For the ?rst time four workshops have been held in conjunction with the 8th Object-Oriented Information Systems conference, OOIS 2002, to encourage - teraction between researchers and practitioners. Workshop topics are, of course, inline with the conference’s scienti?c scope and provide a forum for groups of researchers and practitioners to meet together more closely and to exchange opinions and advanced ideas, and to share preliminary results on focused issues in an atmosphere that fosters interaction and problem solving. The conference hosted four one-day workshops. The four selected workshops were fully in the spirit of a workshop session hosted by a main conference. Indeed, OOIS deals ...

Almost all technical systems currently either interface with or are themselves largely software systems. Software systems must not harm their environment, but are also often vulnerable to security attacks with potentially serious economic, political, and physical consequences, so a better understanding of security and safety and improving the quality of complex software systems are crucial challenges for the functioning of society. This book presents lectures from the 2018 Marktoberdorf summer school Engineering Secure and Dependable Software Systems, an Advanced Study Institute of the NATO Science for Peace and Security Programme. The lectures give an overview of the state of the art in the...
This book provides a comprehensive and accessible introduction to knowledge graphs, which have recently garnered notable attention from both industry and academia. Knowledge graphs are founded on the principle of applying a graph-based abstraction to data, and are now broadly deployed in scenarios that require integrating and extracting value from multiple, diverse sources of data at large scale. The book defines knowledge graphs and provides a high-level overview of how they are used. It presents and contrasts popular graph models that are commonly used to represent data as graphs, and the languages by which they can be queried before describing how the resulting data graph can be enhanced ...
