This book explains the best practices of the UNCTAD & WTO for trade analysis to the R users community. It shows how to replicate the UNCTAD & WTO's Stata codes in the Practical Guide to Trade Policy Analysis by using R. Applications and exercises are chosen from the Practical Guide to Trade...

Für den Objects-first-Ansatz in der Lehre der objektorientierten Programmierung - ohne den Ballast von Klassen - fehlt es bisher an geeigneten Programmiersprachen. Die DOSL (Direct Object Specification Language) erweitert deshalb bisher Smalltalk um die Möglichkeit, Objekte direkt, d.h. ohne...

Techniques such as cellular automata and agent-based modelling have long been used to capture and simulate the temporal dynamics of spatial information. Tools commonly employed to implement spatial simulation models include code libraries and pre-compiled models; the former require advanced...

Model-based engineering is a well-established approach to cope with the complexity of today's embedded systems. Furthermore, model-based engineering can address industry needs for highly automated development solutions to foster correctness of safety-critical systems. In contrast, there is a...

An enterprise model comprises various abstractions of an enterprise that represent both information systems and the surrounding action systems. These different models are integrated in order to avoid redundant work and to contribute to a tight and consistent integration of action systems and...

Die stetig wachsende Komplexität von Hard- und Softwaresystemen sowie der steigende Funktionsumfang bei stets kürzer werdenden Produktzyklen führen zunehmend zum Einsatz von modellbasierten Technologien in der Entwicklung und bei den Tests. Bei der Entwicklung und beim Test solcher komplexer...
