Formation Mechanisms for Entry and Exit Defects in Bobbin Friction Stir Welding
Metals, 2018 Bobbin friction stir welding (BFSW) is an innovative variant for the solid state welding process whereby a rotating symmetrical tool causes a fully penetrated bond.

A graphical approach to analogue behavioural modelling [PDF]
Proceedings of European Design and Test Conference EDAC-ETC-EUROASIC, 2002 In order to master the growing complexity of analogue electronic systems, modelling and simulation of analogue hardware at various levels is absolutely necessary. This paper presents an original modelling method based on the graphical description of analogue electronic functional blocks.

An analogue model of melt segregation and accumulation processes in the Earth’s crust [PDF]
Estonian Journal of Earth Sciences, 2007 An analogue experiment was carried out to model melt segregation from the solid rock matrix and its subsequent transport. Carbon dioxide gas and sand were used as analogue materials of crustal partial melt and host rock, respectively.

Geology and sandbox analogue modelling of the Karatau structural complex (Southern Urals)
BSGF - Earth Sciences BulletinThe Karatau structural complex (KSC) is one of the most complicated geological structures of the Southern Urals. Its complexity is confirmed by the diversity of points of view on the origin: (1) the complex arose due to vertical movements; (2) the ...

Stepwise magma migration and accumulation processes and their effect on extracted melt chemistry [PDF]
Estonian Journal of Earth Sciences, 2009 Numerical and analogue models suggest that melt production, its segregation from the solid matrix and subsequent transport and accumulation are highly dynamic and stepwise processes exhibiting scale invariant patterns in both time and length scales ...

Analogue Modelling of Inverted Oblique Rift Systems
Geologica Acta, 2005 The geometric evolution of brittle fault systems in inverted oblique and offset rift systems has been simulated using scaled sandbox analogue models. Dry fine-grained quartz sand was used to represent the brittle upper crust.

Catastrophizing and Risk-Taking
Computational Psychiatry, 2023 Background: Catastrophizing, when an individual overestimates the probability of a severe negative outcome, is related to various aspects of mental ill-health.

Non-linear behaviour of charge-pump phase-locked loops [PDF]
Advances in Radio Science, 2010 The analysis of the mixed analogue and digital structure of charge-pump phase-locked loops (CP-PLL) is a challenge in modelling and simulation. In most cases the system is designed and characterized using its continuous linear model or its discrete ...

ANALOGUE MODELS FOR FRW COSMOLOGIES [PDF]
International Journal of Modern Physics D, 2003 It is by now well known that various condensed matter systems may be used to mimic many of the kinematic aspects of general relativity, and in particular of curved-spacetime quantum field theory. In this essay we will take a look at what would be needed to mimic a cosmological spacetime — to be precise a spatially flat FRW cosmology — in one of these ...
