Shape descriptors for mode-shape recognition and model updating [PDF]
, 2009 The most widely used method for comparing mode shapes from finite elements and experimental measurements is the Modal Assurance Criterion (MAC), which returns a single numerical value and carries no explicit information on shape features. New techniques,

Collective coordinates, shape transitions and shape coexistence: a microscopic approach [PDF]
, 1998 We investigate a description of shape-mixing and shape-transitions using collective coordinates. To that end we apply a theory of adiabatic large-amplitude motion to a simplified nuclear shell-model, where the approximate results can be contrasted with ...

Sport and the LGBTIQ+ Community: A South Australian Study
Frontiers in Psychology, 2021 This is a paper based on research with the LGBTIQ+ community in South Australia, the likes of which has not been conducted previously in the state. The paper, which utilized both quantitative (n = 148) and qualitative (n = 31) research methods identifies

Algebraic Shape Invariant Models [PDF]
, 1998 Motivated by the shape invariance condition in supersymmetric quantum mechanics, we develop an algebraic framework for shape invariant Hamiltonians with a general change of parameters. This approach involves nonlinear generalizations of Lie algebras. Our

Microstructures and Properties Evolution of Al-Cu-Mn Alloy with Addition of Vanadium
Metals, 2016 The effect of the vanadium addition on the microstructure, the precipitation behavior, and the mechanical properties of the Al-5.0Cu-0.4Mn alloy has been studied. The as-cast Al-5.0Cu-0.4Mn alloy was produced by squeeze casting and the heat treatment was

The Electronic Journal of Combinatorics, 1996 Given a list $1\times 1, 1\times a, 1\times b, \dots, 1\times c$ of rectangles, with $a,b,\dots,c$ non-negative, when can $1\times{t}$ be tiled by positive and negative copies of rectangles which are similar (uniform scaling) to those in the list? We prove that such a tiling exists iff $t$ is in the field $Q(a,b,\dots,c)$.

Shape Complexity in Turbulence [PDF]
, 1998 The shape complexity of irregular surfaces is quantified by a dimensionless area-volume measure. A joint distribution of shape complexity and size is found for level-set islands and lakes in two-dimensional slices of the scalar field of liquid-phase ...
