    The problem of detecting permanent faults in sequential circuits by random testing is analyzed utilizing a continuous parameter Markov model. Given a sequential circuit with certain stuck faults specified, the original state table and its error version can be readily derived from an analysis of the circuit under fault-free and faulty conditions, respectively. By simulation of these two tables on a... View full abstract»

    A novel technique for predicate-formation is given. It is useful for generation of LISP programs from the I/O examples. The top-level elements of I/O lists can be atoms or lists of arbitrary structure, and can be put into two groups, on which different actions are taking place. The predicate generated yields true for elements of one group, while false for other elements. The technique is mainly us... View full abstract»

    Experimental investigations by psychologists have revealed significant deviations of actual human decision behavior from classical rational theories of judgment and decision-making. Weakening the assumptions of the latter has led to the development of such new theories such as prospect theory or rank-dependent subjective expected utility theory. Recent work in this area is reviewed with an emphasi... View full abstract»

    The self-organizing model of feature-detecting cells of S. Amari and A. Takeuchi (Biol. Cybern., vol.29, p.127-36, 1978) is expanded by adding an inhibitory cell with a nonlinear characteristic. The generalized model can form the feature-detecting cells of each pattern, even if the patterns have an inclusion. It is shown that, by varying only a learning parameter in the model, various classificati... View full abstract»

    Previous research has demonstrated that judgements of intent were significantly related to attitudinal, normative, and (global) affective components of decision making. The research failed, however, to demonstrate the distinctiveness of the three components by obtaining convergent and discriminant validity measures. This limitation is addressed. Multiple methods were used to measure each of the th... View full abstract»
