And you claim to have discovered this. .. from observations on sick people? This paper argues that new light may be shed on mathematical reasoning in its non-pathological forms by careful observation of its patholo-gies. The first section explores the application to mathematics of recent work on fallacy theory, specifically the concept of an 'argumentation scheme': a characteristic pattern unde...

We propose a soluble model to incorporate the nonlinear effects in the transition probabilities of the multiphonon Giant Dipole Resonances based on the SU(1,1) algebra. Analytical expressions for the multi-phonon transition probabilities are derived. Enhancement of the Double Giant Resonance exci-tation probabilities in relativistic ion collisions scales as (2k + 1)(2k) −1 for the degree of non...

It is well known that an increase in glycogen content is one of the metabolic changes which estrogen induces in rat uterus, the target organ of the hormone . Although glycogen in the uterus has been considered to be an energy and nutritional source for the implan tation and growth of fertilized ovum, the mechanism of glycogen synthesis in the uterus and the biological significance of the elevat...

This paper describes the development of a practical manipulator system. The manipulator requirements dictated by space exploration, the functional elements which meet those require­ ments, and the problems encountered in imple­ menting those requirements are discussed. The paper focuses primarily on the implemen­ tation of the functional elements and the real world problems encountered by the m...

Because of its wide applicability many e cient implementations of the Fast Fourier Transform have been developed We propose that an e cient implemen tation can be produced automatically and reliably by partial evaluation Partial evaluation of an unoptimized implementation produces a speedup of over times The automatically generated result of partial evaluation has performance com parable to or ...

We address the problem of causal interpre­ tation of the graphical structure of Bayesian belief networks (BBNs). We review the con­ cept of causality explicated in the domain of structural equations models and show that it is applicable to BBNs. In this view, which we call mechanism-based, causality is defined within models and causal asymmetries arise ·, when mechanisms are placed in the conte...

First we explain the interplay between robust loss functions non linear lters and Bayes smoothers for edge preserving image recon struction Then we prove the surprising fact that maximum posterior smoothers are nonlinear lters A generalized Potts prior for segmen tation and piecewise smoothing of noisy signals and images is adopted For one dimensional signals an exact solution for the maximum p...

This paper discusses and contrasts different approaches to the construction of dynamic model> containing unobservables. It is argued that some analysis is easy IO cam out wing Dynamic Factor Analysis (DFA). a frequency domain technique, while other analysis is easier to carry clut in the context of a Dynamic Multiple Indicator-Multiple Cause Model (DYMIMIC), a time domain technique. An example ...

In this paper we show that a phenomenon in animal learning theory (the outcome devaluation eeect) for which there is dispute over whether explicit representations and symbolic reasoning is required for its performance , does not require such things. This is done using a reactive motivational model, previously inspired from ethological thought, to which some simple reinforcement learning rules a...
