Analogue modelling of thyristors
Proceedings of the Institution of Electrical Engineers, 1973The paper is an applications report of an electronic model of an s.c.r.for use in predicting the conducting state of a thyristor. The model is entirely logical in operation, relies purely on voltage signals from the thyristor and does not depend on any current measurements in the main power system. This property allows the model to be used in thyristor

Behavioral analogues of anxiety animal models
Neuropharmacology, 1983In the absence of fully characterized biological indexes, anxiety is at present measured as unpleasant effects reported verbally by patients. Because of the subjective nature of the syndrome, animal analogues have been difficult to design, but quests for new anxiolytics and a deeper understanding of the neurobiology of anxiety have fostered the ...

Analogue models of motion perception
Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1980Abstract An object moving in discrete spatial jumps is difficult to distinguish from a continuously moving object, provided the time between jumps is not too great. The extent of this perceived continuity may be measured by probing the perceived spatial location at times between the target jumps, by either a vernier alignment or a ...

Computing and modelling: Analog vs. Analogue
Studies in History and Philosophy of Science Part A, 2020We examine the interrelationships between analog computational modelling and analogue (physical) modelling. To this end, we attempt a regimentation of the informal distinction between analog and digital, which turns on the consideration of computing in a broader context.

Model Syntheses of Thiazolidine Nucleoside Analogues
Nucleosides and Nucleotides, 1996Abstract The syntheses of racemic thiazolidinyl thymine and cytosine derivatives 6a and 6b, and 10a and 10b, prototypes of a novel family of heterosubstituted nucleosides, have been achieved from rhodanine (3) or thiazolidine (7) by a short sequence of steps.

Hierarchical analogue design and behavioural modelling
Proceedings 1999 IEEE International Conference on Microelectronic Systems Education (MSE'99) 'Systems Education in the 21st Century' (Cat. No.99-63794), 2003This paper describes a new project oriented course which has been set-up recently at the University of Bordeaux, France, in co-operation with the institute of Microelectronics Bordeaux IXL. This course, held within the curriculum of the microelectronics engineer education, introduces the concept of hierarchical design of analogue circuits and analogue ...

Analogue models of transpressive systems
Journal of Structural Geology, 2001This paper presents three series of analogue models of transpressional deformation in a brittle/ductile system: (1) simple transpression, (2) transpression combined with erosion of uplifted areas of the hanging wall above the deformation front, and (3) transpression combined with erosion of the hanging wall and sedimentation at the foot of uplifted ...

Analogue resolution in a model of the Schaffer collaterals
1997We have analytically and numerically solved the mutual information expression for a quantitative model of the Schaffer collateral projections from the CA3 to the CA1 pyramidal cells within the hippocampus. Here we discuss in particular results from the model on the effect of analogue coding levels in the Schaffer collaterals, and the fact that this ...

Analogue models of laccolith formation
Journal of Structural Geology, 1995Abstract This paper describes dynamically scaled analogue models of laccolithic intrusions. Experiments consisted of the injection of a Newtonian fluid (low-viscosity silicone putty) into a sandpack, with or without an interbedded ductile layer of silicone putty acting as a potential decollement level.

Model analogues in the study of cephalic circulation
Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2000Simple laboratory models are useful to demonstrate cardiovascular principles involving the effects of gravity on the distribution of blood flow to the heads of animals, especially tall ones like the giraffe. They show that negative pressures cannot occur in collapsible vessels of the head, unless they are protected from collapse by external structures ...
