Automatic Selection for Non-linear Models [PDF]
, 2012 Our strategy for automatic selection in potentially non-linear processes is: test for non-linearity in the unrestricted linear formulation; if that test rejects, specify a general model using polynomials, to be simplified to a minimal congruent representation; finally select by encompassing tests of specific non-linear forms against the selected model.

Non-local non-linear sigma models
Journal of High Energy Physics, 2019 We study non-local non-linear sigma models in arbitrary dimension, focusing on the scale invariant limit in which the scalar fields naturally have scaling dimension zero, so that the free propagator is logarithmic.

Linear and Non-Linear Models for Remotely-Sensed Hyperspectral Image Visualization
Remote Sensing, 2020 The visualization of hyperspectral images still constitutes an open question and may have an important impact on the consequent analysis tasks. The existing techniques fall mainly in the following categories: band selection, PCA-based approaches, linear ...

Non-linear Hamiltonian models for DNA
European Biophysics Journal, 2022 Nucleic acids' physical properties have been investigated by theoretical methods based both on fully atomistic representations and on coarse-grained models, e.g., the worm-like-chain, taken from polymer physics. In this review article, I discuss an intermediate (mesoscopic) approach and show how to build a three-dimensional Hamiltonian model which ...

Production Constraints Modelling: A Tactical Review Approach [PDF]
Journal of Optimization in Industrial Engineering, 2020 A constraint is a limitation or a restriction that poses a threat to the performance and efficiency of a system. This paper presented a tactical review approach to production constraints modeling.

Linear and non-linear optimization models for the selection of investment portfolio
Lietuvos Matematikos Rinkinys, 2021 This research suggests a maxmin model for the selection of investment portfolios. The risk evaluation coefficients are introduced. The components of portfolio are found by solving linear programming task in onemodel and non-linear programming task in the

Non-linear modelling of breast tissue
Mathematical Medicine and Biology, 2007 Previous approaches to modelling the large deformation of breast tissue, as occurs, e.g. in imaging using magnetic resonance imaging or mammography, include using linear elasticity and pseudo-non-linear elasticity, in which case the non-linear deformation is approximated by a series of small linear isotropic deformations, with the (constant) Young's ...

Non-linear duality invariant partially massless models?
Physics Letters B, 2016 We present manifestly duality invariant, non-linear, equations of motion for maximal depth, partially massless higher spins. These are based on a first order, Maxwell-like formulation of the known partially massless systems.

Non-Linear Macroeconomic Models of Growth with Memory
Mathematics, 2020 In this article, two well-known standard models with continuous time, which are proposed by two Nobel laureates in economics, Robert M. Solow and Robert E. Lucas, are generalized.
