Online Estimation of Internal Short Circuit Resistance for Large-Format Lithium-Ion Batteries Combining a Reconstruction Method of Model-Predicted Voltage

open access: yesWorld Electric Vehicle Journal, 2022
The resistance of the internal short-circuit (ISC) has a potential evolution trend accompanied by an increasing safety risk. Thus, an accurate online resistance estimation for the ISC is crucial for evaluating its safety risk and taking staged handling ...

Spherical distribution vectors [PDF]

open access: yes, 2002
In this paper we consider a locally compact second countable unimodular group $G$ and a closed unimodular subgroup $H$. Let $\rho$ be a finite dimensional unitary representation of $H$ with closed image.

Subjective Distributions [PDF]

open access: yesTheory and Decision, 2004
A decision maker has to choose one of several random variables, with uncertainty known distributions. As a Bayesian she behaves as if she knew the distributions. In his paper we suggest an axiomatic derivation of these (subjective) distributions, which is much more economical than the derivations by de Finetti or Savage.

Castor Oil Derived Insulating Fluid Catalyzed with SnCl2/Zeolite Y [PDF]

open access: yesE3S Web of Conferences
This study investigates the synthesis of ester oil from castor oil via a two-step esterification process using SnCl2/Zeolite Y as a catalyst. Catalyst characterization through SEM-EDX and XRD confirmed the retention of Zeolite Y's porous structure and ...

A Novel Sequence-to-Sequence Prediction Model for Lithium-Ion Battery Capacity Degradation Based on Improved Particle Swarm Optimization

open access: yesBatteries, 2023
The state of health (SOH) evaluation and remaining useful life (RUL) prediction for lithium-ion batteries (LIBs) are crucial for health management. This paper proposes a novel sequence-to-sequence (Seq2Seq) prediction method for LIB capacity degradation ...

A Network Reconfiguration Method Considering Data Uncertainties in Smart Distribution Networks

open access: yesEnergies, 2017
This work presents a method for distribution network reconfiguration with the simultaneous consideration of distributed generation (DG) allocation. The uncertainties of load fluctuation before the network reconfiguration are also considered.

Balance diagnostics for comparing the distribution of baseline covariates between treatment groups in propensity-score matched samples

open access: yesStatistics in Medicine, 2009
The propensity score is a subject's probability of treatment, conditional on observed baseline covariates. Conditional on the true propensity score, treated and untreated subjects have similar distributions of observed baseline covariates.

A study on stabilization of operation time for hydraulic operating circuit breaker (Development of hydraulic stabilization system holding constant high pressure)

open access: yesNihon Kikai Gakkai ronbunshu, 2015
A hydraulic operation stabilizing system was developed for a hydraulic operating mechanism of a gas circuit breaker (GCB). Air bubbles and cavities, created in hydraulic fluid by the movement of the operating mechanism, have an effect on the movement of ...
