Geometric shape of invariant manifolds for a class of stochastic partial differential equations
, 2010 Invariant manifolds play an important role in the study of the qualitative dynamical behaviors for nonlinear stochastic partial differential equations. However, the geometric shape of these manifolds is largely unclear.

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,

Jensen-type geometric shapes [PDF]
Annales Universitatis Paedagogicae Cracoviensis. Studia Mathematica, 2020 Abstract We present both necessary and sufficient conditions for a convex closed shape such that for every convex function the average integral over the shape does not exceed the average integral over its boundary. It is proved that this inequality holds for n-dimensional parallelotopes, n-dimensional balls, and convex ...

The statistical shape of geometric reasoning [PDF]
Scientific Reports, 2018 Abstract Geometric reasoning has an inherent dissonance: its abstract axioms and propositions refer to perfect, idealized entities, whereas its use in the physical world relies on dynamic perception of objects. How do abstract Euclidean concepts, dynamics, and statistics come together to support our intuitive geometric reasoning? Here,
