Comparison of 1D and 3D reservoir heat transport models and temperature effects on mass transport
RBRH, 2019 One and three-dimensional heat transport models are compared in a dendritic reservoir in Brazil. We estimate the periods of temperature stratification for both models using physical indices and temperature gradients.

One-, Two-dimensional Model of Personal Identity and Personal Being, as an Accumulator of “Zombies” Ontology (Regressive Tendency of Combining a Living Body and a Corpse Within a Semantic Field of the “Body” Concept in 19 European Languages and in All Hie [PDF]
, 2018 The aim of research is revealing the correlation of one-, two-dimensional models of personal identity and the ontology of a dead body without signs of consciousness (“zombies”). Research methods are hermeneutic and systemic structural.

SOC Oriented Electrochemical-Thermal Coupled Modeling for Lithium-Ion Battery
IEEE Access, 2019 This paper proposes an electrochemical-thermal coupling model for state of charge (SOC) estimation of lithium-ion batteries (LIBs). In this paper, to solve two numerical problems in the quasi two-dimensional model of LIBs, a simplified one-dimensional ...

Effect of the accuracy of riverbed measurements using adcp on the water surface level at discharge Q1% [PDF]
Acta Scientiarum Polonorum. Formatio Circumiectus, 2018 In order to verify the impact of riverbed measurement using the Acoustic Doppler Current Profiler (ADCP) based on the Doppler effect on the accuracy of the structure of water surface level simulated in the numerical model, two series of field ...

Two dimensional QCD is a one dimensional Kazakov-Migdal model [PDF]
, 1993 We calculate the partition functions of QCD in two dimensions on a cylinder and on a torus in the gauge $\partial_{0} A_{0} = 0$ by integrating explicitly over the non zero modes of the Fourier expansion in the periodic time variable. The result is a one

The Asymmetric One-Dimensional Constrained Ising Model [PDF]
, 2001 We study a reversible one-dimensional spin system with Bernoulli(p) stationary distribution, in which a site can flip only if the site to its left is in state +1. Such models have been used as simple exemplars of systems exhibiting slow relaxation.
