The paper is organised as follows. In Section 2 we give an overview of the Event-B formalism. In Section 3 we present our generic model of a resilient SoS derived by refinement in Event-B. In Section 4 we exemplify the proposed approach by a case study - a satellite flight formation. Einally, in Section 5 we present some concluding remarks and discuss the future work. 

Two synthetic bridged nitrogen heterocycles are also prepared on a commercial scale. The pentazocine synthesis consists of a reductive alkylation of a pyridinium ring, a remarkable and puzzling addition to the most hindered position, hydrogenation of an enamine, and acid-catalyzed substitution of a phenol derivative. The synthesis is an application of the reactivity rules discussed in the alkaloid section. The same applies for clidinium bromide. 

We close these introductory remarks with a few comments on the methods which are actually used to study these models. They will for the most part be mentioned only very briefly. In the rest of this chapter, we shall focus mainly on computer simulations. Even those will not be explained in detail, for the simple reason that the models are too different and the simulation methods too many. Rather, we refer the reader to the available textbooks on simulation methods, e.g.. Ref. 32-35, and discuss only a few technical aspects here. In the case of atomistically realistic models, simulations are indeed the only possible way to approach these systems. Idealized microscopic models have usually been explored extensively by mean field methods. Even those can become quite involved for complex models, especially for chain models. One particularly popular and successful method to deal with chain molecules has been the self-consistent field theory. In a nutshell, it treats chains as random walks in a position-dependent chemical potential, which depends in turn on the conformational distributions of the chains in... 

Despite these critical remarks, this discussion may be summarized by saying that the participation of the nitrosoamine (3.7), of its conjugate O-acid (3.8), of the (Z)-or (i -diazohydroxide (3.9), and of their conjugate acids (3.10) in the system of Scheme 3-36 remains more or less conjectural, but at least the nitrosoamine (3.7) does appear to be reasonable well documented as an intermediate on the pathway to the diazonium ion. 

There have been many reviews and discussions of the crystal chemistry of the Laves phases (among the more recent see Berry Raynor, 1953 Laves, 1956 Elliott Rostoker, 1958 Bardos, Gupta Beck, 1961 Dwight, 1961 Nevitt, 1963) but none of these explicitly discuss what we find to be their most remarkable features ...

The author is very grateful to Drs. J. W. McFarland (Reckon, USA), H. Van de Waterbeemd (AstraZeneca, UK) and K.-J. Schaper (Borstel Research Center, Germany) for collaboration and very useful discussions, and Professor Dr. R. Mannhold for valuable editorial remarks and advice. 

It is difficult to define unequivocally the quality of fabric handle or softness/firmness differences, since this involves many factors. It is often linked with lubrication, especially as similar products are often used for softening and lubrication. Whilst experienced assessors can be quite remarkable in the extent to which they can grade and assess softeners simply by means of a highly developed tactile sense, more objective methods are clearly desirable for scientific investigations. Since many factors combine in producing an overall sense of softness, it is not surprising that objective determination of softness involves more than one parameter of measurement. The details of assessment are outside the scope of this chapter, but descriptions and discussions are available elsewhere [478-481]. Suffice it to say here that the Kawabata system has acquired considerable importance in quantifying various aspects of fabric handle. 

From this discussion, it is evident that the reactions are initially similar nevertheless, the different rings do exercise different degrees of influence on the reactivity of the contiguous hydroxyl group. This makes possible the elimination of water and the formation of rings in different ways. The influence of catalytic agents is in some cases very remarkable, and can be so strong that even in very dilute solutions complete dehydration may occur. 

Abstract After some historical remarks we discuss different criteria of dynamical stability of stars and the properties of the critical states where the loss of dynamical stability leads to a collapse with formation of a neutron star or a black hole. At the end some observational and theoretical problems related to quark stars are discussed. 

As a result of these analyses, several relations between structure types have been shown and discussed. Emphasis has been given to the fact that apparently, in all the structure types considered, Nature prefers one of the most symmetrical AET. Remarkably these AETs are often found equally in single-environment and polyenvironment groups, meaning that even in complex structures, symmetrical... 

Preparation methods of phosphides and polyphosphides have been systematically described and discussed by von Schnering and Honle (1988). The following techniques and remarks, which are also of general interest, may be quoted. 

In this chapter, we provide a general overview of the field of chemometrics. Some historical remarks and relevant literature to this subject make the strong connection to statistics visible. First practical examples (Section 1.5) show typical problems related to chemometrics, and the methods applied will be discussed in detail in subsequent chapters. Basic information on univariate statistics (Section 1.6) might be helpful to understand the concept of randomness that is fundamental in statistics. This section is also useful for making first steps in R. 

An introduction to the non-covalent forces operating in stable ionic and molecular aggregates will be presented in Section 2. A brief description of the experimental methodologies employed in the production, detection, and characterization of clusters will be given in Section 3. The available experimental evidence on the structure of chiral clusters and their intrinsic stability, reactivity, and evolution dynamics will be presented and discussed in Sections 4 (molecular clusters) and 5 (ionic clusters). In the same sections, the experimental data will be interpreted in the light of the available theoretical evidence. Finally, some concluding remarks will be expressed in Section 6.

Move 1 (Interpret or Explain Results) is often integrated into the poster Results section, thereby becoming a combined Results and Discussion (R D) section. An example of a combined R D section is shown in hgure 9.1. In such posters, interpretative remarks (Discussion) are included right along with the graphics (Results). In this way, space is conserved, and viewers can read and interpret the data simultaneously (usually easier than looking back and forth between the two sections). For instructional purposes, however, we have placed move 1 in the Discussion section, and we use a stand-alone Discussion section in the three hypothetical posters presented below. We follow this approach, in part, to maintain a clear distinction between results (just the facts) and discussion (interpretation of the facts). 

Consider the key results of your work. How can you use text to highlight, explain, and interpret these results Decide if you want a combined Results and Discussion section, with explanatory remarks included along with the graphics, ora stand-alone Discussion section. 

This chapter starts with a brief summary of the old and novel experimental investigations on KDP-type ferroelectrics that are most relevant for the discussion of the present topic. A brief history of theoretical models for KDP, development of the SDPC and MSDPC models, and appUed munerical methods are described in Sect. 3. The most important results of the MSDPC model are presented and discussed in Sect. 4, whereas comments about the model and concluding remarks are given in Sect. 5.
