Pioneering work into Very Large Scale Integration VLSI and the theory of computation reveals a new revolution. Quantum physics is essential to the understanding of deuces with two stable states and to how theoretically, classical Turing computation is physically possible. Furthermore, completely novel quantummechanical computational devices utilizing dimensional confinement can be made similar mechanisms may well exist in natural biological systems and brains. Shows that this new quantummechanical perspective yields the basis for a model of conscious machinery, with correspondingly well defined processes specifying the nature of perception, cognition and information, for which as yet computer science has no agreed definitions.

Mathematical models have been constructed to aid in the understanding of the pharmacokinetics of different drugs. Gives a mathematical analysis of the courses over time of absorption, distribution and elimination of a drug in a sixcompartment linear mammillary model. A mammillary model is a compartmental model in which a central compartment the udder of a cow is related to all other compartments, but there are no relations between the latter. This linear mammillary model can be used to study the kinetics of protein metabolism in the organism. An optimization method ALIENOR is used which reduces the unknown parameters involved to a single variable. Thus, the problem requires the global minimum of a function of a single variable. The results obtained with the method described are compared with those obtained with the generalized leastsquares method.

Describes a method of construction and representation of scientific knowledge, as a hierarchical information structure, using the propositional form of semantinet formulism. The method can be used for developing knowledgebased systems and, in particular, ComputerAssisted Learning CAL programs. The method is theoretically based on issues taken from both psychology and computer sciences, and particularly the cognitive aspects of memory organization and the conversation and comprehension processes. Scientific knowledge is regarded as being made up of three types of information definitions, methods and procedures. Each type consists of information represented by separate and meaningful properties, together with their relationships and the processes that may occur in using this information during comprehension and conversation.

Analyses the possibility of allowing nonlinear synaptic processing in Artificial Neural Networks ANN both theoretically and practically. The simple computer simulations described strongly suggest that this is a viable alternative, and preferable to ANN with just linear synapses, because of the savings in hardware fewer components are needed and software reduction in training time when dealing with similar problems. Derives some considerations regarding a possible relationship between the parallel processor proposed and living nerve cells.

In the construction of Beer's Predictive Model for control of operations in complex probabilistic systems a major exercise is the adjustment of resources to meet current productivity values so as to stabilize overall system output. There arise, however, certain theoretical problems in this adjustment exercise and this communication examines some of them.
