An analytical model for elasto-plastic buckling of columns [PDF]

open access: yes, 2013
The theory of buckling strength of compression members in the plastic range has been extensively studied, and numerical methods already exist which deal with such behaviour.

Analytical ground state for the three-band Hubbard model

open access: yes, 1999
For the calculation of charge excitations as those observed in, e.g., photo-emission spectroscopy or in electron-energy loss spectroscopy, a correct description of ground-state charge properties is essential.

A Simple Analytical Model for Gaps in Protoplanetary Disks

open access: yes, 2015
An analytical model is presented for calculating the surface density as a function of radius $\Sigma(r)$ in protoplanetary disks in which a planet has opened a gap. This model is also applicable to circumbinary disks with extreme binary mass ratios.

Optimum Analytical Model for the Drift Region of Silicon Carbide Uni-polar Power Device

open access: yesKongzhi Yu Xinxi Jishu, 2015
Currently,doping concentration uniformity of epi-wafers is poor and thickness of epi-layer is sensitive to cost and defect density. An optimum analytical model for the drift region of uni-polar silicon carbide (SiC) power device and an optimum control ...

Analytical modelling of laminated composites

open access: yesComposites Science and Technology, 1993
This paper presents a unique approach to the analysis of thick laminated composites by presenting two simple finite element methods. The first uses the predictor corrector technique to extend the simple Mindlin-type element to achieve greater accuracy, and the second develops a new least squares element which can approximate a C(1) continuous element ...

Analytical Model for the Structural Behavior of Pipelines During Lowering-In

open access: yesApplied Sciences, 2019
Since pipelines experience the largest deformation during lowering-in, structural analysis for this construction sequence should be performed to ensure structural safety.

An Analytical Model for the Triaxial Collapse of Cosmological Perturbations

open access: yes, 1994
We present an analytical model for the non-spherical collapse of overdense regions out of a Gaussian random field of initial cosmological perturbations.

Analytical Image Models and Their Applications [PDF]

open access: yes, 2002
In this paper, we study a family of analytical probability models for images within the spectral representation framework. First the input image is decomposed using a bank of filters, and probability models are imposed on the filter outputs (or spectral components).

Modeling of Zinc Dynamics in the Synaptic Cleft: Implications for Cadherin Mediated Adhesion and Synaptic Plasticity

open access: yesFrontiers in Molecular Neuroscience, 2018
While the numerous influences of synaptically released zinc on synaptic efficiency during long-term potentiation have been discussed by many authors already, we focused on the possible effect of zinc on cadherins and therefore its contribution to ...

Analytical model for laser-assisted recombination of hydrogenic atoms

open access: yes, 2011
We introduce a new method that allows one to obtain an analytical cross section for the laser-assisted electron-ion collision in a closed form. As an example we perform a calculation for the hydrogen laser-assisted recombination.
