Application of deep learning image recognition for lithium battery State of Health assessment

Energy Conversion and Economics, EarlyView.
Abstract Accurately estimating the State of Health (SOH) of lithium‐ion batteries is essential for ensuring their reliable operation. The constant‐current charging voltage curves of batteries at different aging levels show significant deviations.

Calculation and experimental verification of equivalent distributed circuit model based on refined iron core modelling

High Voltage, EarlyView.
Abstract This research introduces an equivalent circuit model and a computational method to address complex mechanical motion issues through electromechanical analogies. The study initially refines core vibration characteristics using single‐ and multi‐degree‐of‐freedom models, subsequently establishing equivalent circuit models for these various ...

The Analysis of Contour Integrals

Abstract and Applied Analysis, 2008
For any 𝑛, the contour integral 𝑦=cosh𝑛+1𝑥∮𝐶(cosh(𝑧𝑠)/(sinh𝑧−sinh𝑥)𝑛+1𝑑𝑧,𝑠2=−𝜆, is associated with differential equation 𝑑2𝑦(𝑥)/𝑑𝑥2+(𝜆+𝑛(𝑛+1)/cosh2𝑥)𝑦(𝑥)=0. Explicit solutions for 𝑛=1 are obtained.

A (3+1)-dimensional generalized BKP-Boussinesq equation: Lie group approach

Results in Physics, 2019
A (3+1)-D generalized B-type KP-Boussinesq equation, which was recently formulated in the literature, is investigated here from Lie group standpoint. A solution is obtained by Lie symmetry reductions and direct integration in terms of incomplete elliptic

Uncovering Price Patterns in the Raw Milk Markets of Central and Southeast European Countries: Implications for Farm Economic Resilience

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT We employ state‐space models to analyse the trend, seasonal component and cycle of farmgate milk prices in Balkan countries, namely Greece, Bulgaria and Slovenia, and in Hungary. We split the time span in 2016 to assess whether the dairy policies undertaken until the abolition of the milk quota system have affected the price cycles.

Cascading Effects of Anthropogenic Excess Food for Predators on a Peri‐Urban Population of an Endangered Ungulate

Animal Conservation, EarlyView.
Cascading effects of anthropogenic excess food for predators on a peri‐urban population of an endangered ungulate (Gazella gazella). ABSTRACT A major side effect of urbanization is the increased availability of food for wildlife in peri‐urban areas.
