Extensions of rich words [PDF]

, 2013
In [X. Droubay et al, Episturmian words and some constructions of de Luca and Rauzy, Theoret. Comput. Sci. 255 (2001)], it was proved that every word w has at most |w|+1 many distinct palindromic factors, including the empty word.

Sliding-windowed weighted recursive least-squares method for parameter estimation

Electronics Letters, 1989
Two popular windowing techniques in conjunction with recursive least- squares (RLS) are the exponential window (WRLS) and the sliding rectangular window (SRRLS) method. The authors propose a modified version of WRLS by employing the sliding window. In this method, namely SWRLS, two windowing techniques are adopted: one is the exponentially weighted ...

A Novel Variable Forgetting Factor Recursive Least Square Algorithm to Improve the Anti-Interference Ability of Battery Model Parameters Identification

IEEE Access, 2019
Recursive least square (RLS) algorithms are considered as a kind of accurate parameter identification method for lithium-ion batteries. However, traditional RLS algorithms usually employ a fixed forgetting factor, which does not have adequate robustness ...

The parameter identification of the autonomous underwater vehicle based on multi-innovation least squares identification algorithm

International Journal of Advanced Robotic Systems, 2020
An accurate model is important for the engineer to design a robust controller for the autonomous underwater vehicle. There are two factors that make the identification difficult to get accurate parameters of an AUV model in practice.

Vestibular Patient Journey: Insights From Vestibular Disorders Association (VeDA) Registry

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Vestibular symptoms impose a high burden of disability. Understanding real‐world diagnostic and treatment pathways can identify care gaps and guide interventions. We aimed to characterize symptom profiles, diagnostic trends, provider involvement, and treatment patterns in vestibular disorders.

Bioinspired Adaptive Leg‐Claw Enables Robust Perching and Grasping for UAVs

Advanced Science, EarlyView.
Inspired by owl limb morphology and bat roosting behavior, this study presents a bioinspired adaptive leg‐claw mechanism that enables UAVs to perform robust and versatile perching and grasping. The design integrates a four‐link tibial structure, tension‐driven deformable feet, and active control, enabling stable perching on various branches and ...

A novel online identification algorithm of lithium‐ion battery parameters and model order based on a fractional order model

IET Renewable Power Generation, 2021
A fractional order equivalent circuit model with variable order can better reflect the internal reaction mechanism of a lithium‐ion battery, however, it is not easy to simultaneously identify the parameters and order of the fractional order model online.
