Sommario/riassunto

Congestion Control in Data Transmission Networks details the modeling and control of data traffic in communication networks. It shows how various networking phenomena can be represented in a consistent mathematical framework suitable for rigorous formal analysis. The monograph differentiates between fluid-flow continuous-time traffic models, discrete-time processes with constant sampling rates, and sampled-data systems with variable discretization periods. The authors address a number of difficult real-life problems, such as: • optimal control of flows with disparate, time-varying delay; • the existence of source and channel nonlinearities; • the balancing of



quality of service and fairness requirements; and • the incorporation of variable rate allocation policies. Appropriate control mechanisms which can handle congestion and guarantee high throughput in various traffic scenarios (with different networking phenomena being considered) are proposed. Systematic design procedures using sound control-theoretic foundations are adopted. Since robustness issues are of major concern in providing efficient data-flow regulation in today’s networks, sliding-mode control is selected as the principal technique to be applied in creating the control solutions. The controller derivation is given extensive analytical treatment and is supported with numerous realistic simulations. A comparison with existing solutions is also provided. The concepts applied are discussed in a number of illustrative examples, and supported by many figures, tables, and graphs walking the reader through the ideas and introducing their relevance in real networks.

Sommario/riassunto

This book is an attempt to analyse psychic language and its diverse modes of expression, both within psychic structure and in the interpersonal realm. It begins by looking at two basic forms of delay in the development of psychic language: concrete language, which is based on flattening, and pseudo-language, which is rooted in concealment. The next chapter focuses on the split between voice and meaning which marks psychotic syntax, and the latter's double function in defending the self against an unconscious death wish. The subject of the third chapter is the chameleon language of perversion, and the relationship between the perverse structure and the primal scene. This chapter is followed by one that suggests understanding autistic syntax as an inverse use of the psychic musical 'organ point'. The fifth chapter discusses the absent function of the inner witness in traumatic language. The sixth chapter discusses psychosomatic language through the distinction between metaphorical, metonymical and psychotic bodily expressions.
