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,

Updating Internal Cognitive Models during Sleep [PDF]
The Journal of Neuroscience, 2019 It is well known that a night of good sleep reinforces various cognitive functions, including memory processing (for review, see [Lim and Dinges, 2010][1]). Specifically, the consolidation of newly acquired memories is thought to benefit from sleep ([Rasch and Born, 2013][2]), based on ...

Model updating of wind turbine blade cross sections with invertible neural networks
Wind Energy, 2022 Fabricated wind turbine blades have unavoidable deviations from their designs due to imperfections in the manufacturing processes. Model updating is a common approach to enhance model predictions and therefore improve the numerical blade design accuracy ...

Updating Experimental Models of Diabetic Cardiomyopathy [PDF]
Journal of Diabetes Research, 2015 Diabetic cardiomyopathy entails a serious cardiac dysfunction induced by alterations in structure and contractility of the myocardium. This pathology is initiated by changes in energy substrates and occurs in the absence of atherothrombosis, hypertension, or other cardiomyopathies.

Bayesian Learning for a Class of Priors with Prescribed Marginals [PDF]
, 2006 We present Bayesian updating of an imprecise probability measure, represented by a class of precise multidimensional probability measures. Choice and analysis of our class are motivated by expert interviews that we conducted with modelers in the context ...
