Logic Programming is the name given to a distinctive style of programming, very different from that of conventional programming languages such as C++ and Java. Fans of Logic Programming would say that 'different' means clearer, simpler and generally better! Although there are other Logic Programming languages, by far the most widely used is Prolog. The name stands for Programming in Logic. This book teaches the techniques of Logic Programming through the Prolog language. Prolog is based on research by computer scientists in Europe in the 1960s and 1970s, notably at the Universities of Marseilles, London and Edinburgh. The first implementation was at the University of Marseilles in the early 1970s. Further development at the University of Edinburgh led to a de facto standard version, now known as Edinburgh Prolog. Prolog has been widely used for developing complex applications, especially in the field of Artificial Intelligence. Although it is a general-purpose language, its main strengths are for symbolic rather than for numerical computation.

Another book on Quantum Optics? or Quantum Information? Well, not exactly. A more descriptive title might be: “A guided tour through basic quantum mechanics, quantum optics and quantum information”. Even better, a few words on its origin and our motivation for undertaking the task might be useful to the potential reader in deciding whether to turn the pages beyond this preface.

This is a tutorial paper on the tool Uppaal. Its goal is to be a short introduction on the flavor of timed automata implemented in the tool, to present its interface, and to explain how to use the tool. The contribution of the paper is to provide reference examples and modeling patterns.

指针逻辑的出发点是：所有不同的访问路径都代表不同的对象，除非能证明它们代表同一个对象。因此指针逻辑需要收集有效指针相等信息，以便知道哪些不同访问路径代表同一个对象。这是指针逻辑不用引入新连接词的原因。 这比较符合习惯：在通常的逻辑中，不相同的名字总代表不同的对象，没有别名的概念。Hoare逻辑就是基于不同名字代表不同对象。

This book is on model checking, a prominent formal verification technique for assessing functional properties of information and communication systems. Model checking requires a model of the system under consideration and a desired property and systematically checks whether or not the given model satisfies this property. Typical properties that can be checked are deadlock freedom, invariants, and request-response properties. Model checking is an automated technique to check the absence of errors (i.e., property violations) and alternatively can be considered as an intelligent and effective debugging technique. It is a general approach and is applied in areas like hardware verification and software engineering. Due to unremitting improvements of underlying algorithms and data structures together with hardware technology improvements, model-checking techniques that two decades ago only worked for simple examples are nowadays applicable to more realistic designs. It is fair to say that in the last two decades model checking has developed as a mature and heavily used verification and debugging technique.

This volume comprises the final versions of the technical papers presented at the
UML 2004 conference held in Lisbon (Portugal), October 11–15, 2004.
UML 2004 was the seventh conference in a series of annual
UML conferences. The series started in 1998 and was located at Mulhouse (France); the following years saw the conference move to Fort Collins (USA) in 1999, York (UK) in 2000, Toronto (Canada) in 2001, Dresden (Germany) in 2002, San Francisco (USA) in 2003, and now Lisbon (Portugal) in 2004. During this time, the
UML conference became one of the leading conferences in the area of object-oriented modeling. While in the first years the focus of the conference was on the scientific investigation of the Unified Modeling Language (UML), which had just been adopted by the Object Management Group (OMG) at the time, the focus has changed in recent years to innovations in techniques such as metamodeling, model transformations, model validation and verification, aspect orientation, and beyond. Many recent research activities have been especially stimulated by the Model Driven Architecture (MDA) initiative, started in 2000 by the OMG. The goal of MDA is the definition of a framework to enable the development of software purely based on models. In order to reflect the changes of recent years, the conference series
UML will be continued, from 2005 onwards, under the name MODELS (MOdel Driven Engineering, Languages and Systems). The call
