Task-Driven Adaptive Statistical Compressive Sensing of Gaussian Mixture Models [PDF]
, 2012 A framework for adaptive and non-adaptive statistical compressive sensing is developed, where a statistical model replaces the standard sparsity model of classical compressive sensing.

Eulerian-Lagrangian Analysis of Multiphase Flow in Urea Prilling Process with Phase Changing
Chemical Engineering Transactions, 2013 The objective of this work is the mathematical formulation of a prilling tower taking into account the solidification of the urea droplets, calculated by a shrinking unsolidified core model. The multiphase gas- liquid flow was modelled using the Eulerian-

An Ising-type formulation of the six-vertex model
Nuclear Physics B, 2023 We show that the celebrated six-vertex model of statistical mechanics (along with its multistate generalizations) can be reformulated as an Ising-type model with only a two-spin interaction.

Coupling Nonlinear Sigma-Matter to Yang-Mills Fields: Symmetry Breaking Patterns [PDF]
, 2008 We extend the traditional formulation of Gauge Field Theory by incorporating the (non-Abelian) gauge group parameters (traditionally simple spectators) as new dynamical (nonlinear-sigma-model-type) fields.

Medical Image Denoising by Improved Kuan Filter
Advances in Electrical and Electronic Engineering, 2012 This paper focuses on the issue of speckle noise and its suppression. Firstly, the multiplicative speckle noise model and its mathematical formulation are introduced. Then, certain de-noising methods are described together with possible improvements.

Outline of a Generalization and a Reinterpretation of Quantum Mechanics Recovering Objectivity
, 2015 The ESR model has been recently proposed in several papers to offer a possible solution of the problems raising from the nonobjectivity of physical properties in quantum mechanics (QM) (mainly the objectification problem of the quantum theory of ...

Finite element surface registration incorporating curvature, volume preservation, and statistical model information [PDF]
, 2013 We present a novel method for nonrigid registration of 3D surfaces and images. The method can be used to register surfaces by means of their distance images, or to register medical images directly.
