Multiscale Analysis of Anisotropy of Reynolds Stresses, Subgrid Stresses and Dissipation in Statistically Planar Turbulent Premixed Flames

Applied Sciences, 2022
The characterisation of small-scale turbulence has been an active area of research for decades and this includes, particularly, the analysis of small-scale isotropy, as postulated by Kolmogorov.

Entropic Approach to Multiscale Clustering Analysis [PDF]

Entropy, 2012
Recently, a novel method has been introduced to estimate the statistical significance of clustering in the direction distribution of objects. The method involves a multiscale procedure, based on the Kullback–Leibler divergence and the Gumbel statistics of extreme values, providing high discrimination power, even in presence of strong background ...

The spectrum of the force-based quasicontinuum operator for a homogeneous periodic chain [PDF]

, 2012
We show under general conditions that the linearized force-based quasicontinuum (QCF) operator has a real, positive spectrum. The spectrum is identical to that of the quasinonlocal quasicontinuum (QNL) operator in the case of second-neighbor interactions.

Multi-Scale Dynamic Analysis of the Russian–Ukrainian Conflict from the Perspective of Night-Time Lights

Applied Sciences, 2022
Under the influence of various forces, the conflict between Russia and Ukraine is violent and changeable. The obtaining of battlefield data by conventional means is difficult but necessary in order to ensure security, reliability, and comprehensiveness ...

Bayesian texture classification and retrieval based on multiscale feature vector [PDF]

, 2011
This paper proposes a supervised multiscale Bayesian texture classifier. The classifier exploits the dual-tree complex wavelet transform (DT-CWT) to obtain complex-valued multiscale representations of training texture samples for each texture class. The

Probabilistic multiscale analysis of inelastic localized failure in solid mechanics

Computer Assisted Methods in Engineering and Science, 2017
In this work, we discuss the role of probability in providing the most appropriate multiscale based uncertainty quantification for the inelastic nonlinear response of heterogeneous materials undergoing localized failure.

Pore resolved simulations of joule heating in fibrous media using an embedded boundary method

Results in Engineering
Joule heating has been regarded as an energy-efficient and sustainable method for heating various materials and gases at large scales. The modeling of Joule heating at pore-resolved scales for such systems, however, has been challenging due to ...
