Spin Model for Inverse Melting and Inverse Glass Transition [PDF]
Physical Review Letters, 2004 A spin model that displays inverse melting and inverse glass transition is presented and analyzed. Strong degeneracy of the interacting states of an individual spin leads to entropic preference of the "ferromagnetic" phase, while lower energy associated with the non-interacting states yields a "paramagnetic" phase as temperature decreases.

An Inverse Model for Estimating Elasticity of the Arterial Wall using Immersed Boundary Method [PDF]
, 2007 Atherosclerosis generally occurs near the branching in the arteries where there tends to be flow irregularities. A build up of fatty deposits (plaque) occurs in the blood vessel in such regions making it to lose its elasticity.

Inverse modeling of European CH4 emissions: sensitivity to the observational network
, 2009 Inverse modeling is widely employed to provide “top-down” emission estimates using atmospheric measurements. Here, we analyze the dependence of derived CH4 emissions on the sampling frequency and density of the observational surface network, using the ...

An inverse model problem in kinetic theory [PDF]
, 1994 The paper deals with an inverse model problem in linear kinetic theory: the identification of a density profile of a scattering medium in a slab geometry from measurement of the reflected portion of a particle flux entering the medium.

Inverse procedural modeling of facade layouts [PDF]
ACM Transactions on Graphics, 2014 In this paper, we address the following research problem: How can we generate a meaningful split grammar that explains a given facade layout? To evaluate if a grammar is meaningful, we propose a cost function based on the description length and minimize this cost using an approximate dynamic programming framework.

ReactionsOne of the challenges in Fischer–Tropsch synthesis (FTS) is the high reduction temperatures, which cause sintering and the formation of silicates. These lead to pore blockages and the coverage of active metals, particularly in conventional catalyst ...

Trajectory Control of Flexible Manipulators Using Forward and Inverse Models with Neural Networks
VibrationThis study explores trajectory control in flexible manipulators using neural-network-based forward and inverse modeling. Unlike traditional approaches that enhance precision by increasing structural rigidity—often at the cost of added weight and energy ...

3D inverse dynamic modeling of strands [PDF]
ACM SIGGRAPH 2011 Posters, 2011 In this poster, we propose a new method to automatically and consistently convert 3D splines into dynamic rods at rest under gravity, bridging the gap between the modeling of 3D strands (such as hair, plants) and their physics-based animation.
