Designing a complex system such as a control, automation or electronic system most engineering activities involve graphical representations for the different design and modelling stages. Starting the design cycle the structure and function of the system has to be specified. For ease of imagination and decision the difficult interrelations between system components and subfunctions are frequently depicted by graphical schematics and diagrams. In this paper we introduce the idea and basic functions of a general purpose Computer Aided Schematics (CAS) system that may assist efficiently all schematics-based processes ranging from interactive to completely automatic drawing including the interfaces to further data processing. We discuss the benefits of the CAS approach as rapid generation and updating of correct and consistent graphics and its impact on the whole design and documentation cycle. Furthermore, some of the intricate, mainly graph theoretical optimization problems inherent in the computer generated layout of schematic drawings are addressed. Finally, we outline the possible application of CAS techniques to different engineering disciplines, where graphical programming and documentation of programmable controllers (PC's) is believed to be a profitable domain. First encouraging experience in the automatic documentation of complex control programs is reported.

the purpose of this paper is the working out of several suitable approximate models of a experimental solar energy system which are successively compared on the resultant approximation. Distributed and lumped parameter mathematical models from the third to the fifth order have been developed. Initially a distributed nonlinear 5th order model, derived from basic physical balance equations, is analysed. this model-building is assumed as the standard, from which both reduced and approximate models are obtained. Various kinds of lumped models are, successively, considered on the basis of theoretical and experimental hypoteses. the various models are tested by simulation comparing their outputs with experimental data.

A survey is presented of what is commonly referred to as modern controltheory involving modelling in state space and optimal control of deterministic and stochastic systems, state- and parameter estimation and adaptive control. Some of the advantages and disadvantages of modern controltheory as compared to conventional controltheory are discussed. Examples of the successful use of modern controltheory to the control of important physical processes are presented and evaluated.

the papers referred to here are grouped in the proceedings of the conference under the heading: Single Neural Units and CNS (Central Nervous System) Complexes. the first (commentary) paper states that a review of the papers submitted to this symposium confirms the impression gained from a reading of the literature of the sixties that the major lines of theoretical development in neurophysiology were established in the first half of the cybernetic period. Foremost among these were (1) the development of the Hodgkin-Huxley equations predicting the ionic fluxes underlying nerve excitation;(2) the application of linear systems analysis in the study of neurological controlsystems;(3) the introduction of data processing and modeling techniques in the study of the brain slow wave and unit potentials;(4) the transfer of communications and information theoretic techniques to the study of signal detection and processing by the brain;(5) the recognition of certain quantal and random processes as fundamental to neuronal systems;(6) the extension of automata and computer theory to the conceptual formulation of certain brain functions;and (7) the elaboration of the first theoretical ideas of structure and function in sensory neuronal networks. Following is a list of titles and authors: theoretical Neurophysiology;An Overview from the Underworld. By George P. Moore. Effects of Metabolic Inhibitors on and a Nonlinear Oscillator Model of Pacemaker Neurons. By M. Kim. Identification of Neural Pulse Modulators. By Michael J. Korenberg. modelling Depression of Monosynaptic Reflex Discharge. By Marcello Crivellini, Mario Decandia, Luigi Divieti, and Michele Maini.
