Train Performance Analysis Using Heterogeneous Statistical Models

open access: yesAtmosphere, 2021
This study investigated the effect of a harsh winter climate on the performance of high-speed passenger trains in northern Sweden. Novel approaches based on heterogeneous statistical models were introduced to analyse the train performance to take time ...

Statistical Models of Alkaline Batteries Discharge

open access: yesInternational Journal of Electrochemical Science, 2015
In this study, there was proved by experiments that the way, in which the activation-ohmic addend in Shepherd’s and Tremblay’s empiric equations and their generalizations describes activation-ohmic processes during a battery discharge by direct current ...

Parsimonious statistical learning models for low-flow estimation [PDF]

open access: yesHydrology and Earth System Sciences, 2022
Statistical learning methods offer a promising approach for low-flow regionalization. We examine seven statistical learning models (Lasso, linear, and nonlinear-model-based boosting, sparse partial least squares, principal component regression, random ...

Statistical physics of pairwise probability models

open access: yesFrontiers in Computational Neuroscience, 2009
Statistical models for describing the probability distribution over the states of biological systems are commonly used for dimensional reduction. Among these models, pairwise models are very attractive in part because they can be fit using a reasonable

Statistical transmutation in doped quantum dimer models [PDF]

open access: yes, 2012
We prove a "statistical transmutation" symmetry of doped quantum dimer models on the square, triangular and kagome lattices: the energy spectrum is invariant under a simultaneous change of statistics (i.e.

Relaxation in statistical many-agent economy models [PDF]

open access: yes, 2007
We review some statistical many-agent models of economic and social systems inspired by microscopic molecular models and discuss their stochastic interpretation.

Non-equilibrium Statistical Approach to Friction Models [PDF]

open access: yes, 2015
A geometric approach to the friction phenomena is presented. It is based on the holographic view which has recently been popular in the theoretical physics community. We see the system in one-dimension-higher space.

On statistical models on super trees

open access: yesJournal of High Energy Physics, 2018
We consider a particular example of interplay between statistical models related to CFT on one hand, and to the spectral properties of ODE, known as ODE/IS correspondence, on the other hand. We focus at the representation of wave functions of Schrödinger

Significant results: statistical or clinical? [PDF]

open access: yesKorean Journal of Anesthesiology, 2016
The null hypothesis significance test method is popular in biological and medical research. Many researchers have used this method for their research without exact knowledge, though it has both merits and shortcomings. Readers will know its shortcomings,
