Three-Dimensional Vertex Model in Statistical Mechanics, from Baxter-Bazhanov Model [PDF]

open access: yes, 1995
We find that the Boltzmann weight of the three-dimensional Baxter-Bazhanov model is dependent on four spin variables which are the linear combinations of the spins on the corner sites of the cube and the Wu-Kadanoff duality between the cube and vertex ...

Detection of Changes in Oil Well Power Consumption Profile on the Basis of Dynamic Time Warping Algorithm

open access: yesProceedings of the International Conference on Applied Innovations in IT, 2018
At present oil companies are forced to continually decrease electric power inputs. However, energy efficiency of oil well equipment decreases in time. Well re-equipment enables to stop energy efficiency loss but it requires large additional inputs.

Statistical model optimized random forest regression model for concrete dam deformation monitoring

open access: yes, 2018
The unique structures and foundations of a dam make its safety monitoring a complex task. As the most intuitive effect of dams, deformation contains important information on dam evolution.

Statistical physics of the Schelling model of segregation

open access: yes, 2007
We investigate the static and dynamic properties of a celebrated model of social segregation, providing a complete explanation of the mechanisms leading to segregation both in one- and two-dimensional systems.

On Timing Model Extraction and Hierarchical Statistical Timing Analysis [PDF]

open access: yes, 2013
In this paper, we investigate the challenges to apply Statistical Static Timing Analysis (SSTA) in hierarchical design flow, where modules supplied by IP vendors are used to hide design details for IP protection and to reduce the complexity of design and

A statistical model of deformation during the construction of a concrete face rockfill dam

open access: yes, 2018
Monitoring data collected during dam construction are important in complete series of monitoring data. These data play a significant role in dam safety monitoring and the analysis of structural conditions.

BCS Model in Tsallis' Statistical Framework

open access: yes, 2001
We show that there is an effect of nonextensivity acting upon the BCS model for superconductors in the ground state that motivates its study in the Tsallis' statistical framework. We show that the weak-coupling limit superconductors are well described by

Generating atmospheric forcing perturbations for an ocean data assimilation ensemble

open access: yesTellus: Series A, Dynamic Meteorology and Oceanography, 2019
Running ensemble of reanalyses or forecasts has proved successful at improving their performances, despite the cost. Generating ensemble simulations requires generating perturbations within the models, and for the assimilated observations and subsidiary ...
