Identifying shape transformations from photographs of real objects. [PDF]

open access: yesPLoS ONE, 2018
An important task of human visual cognition is to make inferences about properties of objects. One such property is an object's causal history: what happened to the object in its past (e.g., "this paper has been folded").

Stress-Induced Phase Transformations in Shape-Memory Polycrystals [PDF]

open access: yes, 2008
Shape-memory alloys undergo a solid-to-solid phase transformation involving a change of crystal structure. We examine model problems in the scalar setting motivated by the situation when this transformation is induced by the application of stress in a ...

Vesicle Shapes and Shape Transformations: A Systematic Study [PDF]

open access: yes, 1991
In our contribution we report a systematic experimental and theoretical study on shape transformations. In order to avoid the above mentioned complications we have investigated vesicles which consist of electrically neutral lipids (that is phosphatidylcholine) in Millipore water.

Microfabrication Using Shape‐Transforming Soft Materials [PDF]

open access: yesAdvanced Functional Materials, 2020
AbstractThe fabrication of hollow and multicomponent micro‐objects with complex inner structures using state‐of‐the‐art subtractive, formative, and additive manufacturing technologies is challenging. Controlled shape transformation offers a very elegant solution to this challenge.

Method for arbitrary phase transformation by a slab based on transformation optics and the principle of equal optical path [PDF]

open access: yes, 2012
The optical path lengths travelled by rays across a wavefront essentially determine the resulting phase front irrespective of the shape of a medium according to the principle of equal optical path.

Shape descriptors for mode-shape recognition and model updating [PDF]

open access: yes, 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,

Momentum distribution of a freely expanding Lieb-Liniger gas [PDF]

open access: yes, 2009
We numerically study free expansion of a few Lieb-Liniger bosons, which are initially in the ground state of an infinitely deep hard-wall trap. Numerical calculation is carried out by employing a standard Fourier transform, as follows from the Fermi-Bose

Functional inversion for potentials in quantum mechanics [PDF]

open access: yes, 1999
Let E = F(v) be the ground-state eigenvalue of the Schroedinger Hamiltonian H = -Delta + vf(x), where the potential shape f(x) is symmetric and monotone increasing for x > 0, and the coupling parameter v is positive. If the 'kinetic potential' bar{f}(s)
