Hyers–Ulam–Rassias stability of fractional delay differential equations with Caputo derivative
Mathematical Methods in the Applied Sciences, Volume 47, Issue 18, Page 13499-13509, December 2024.This paper is devoted to the study of Hyers–Ulam–Rassias (HUR) stability of a nonlinear Caputo fractional delay differential equation (CFrDDE) with multiple variable time delays. We obtain two new theorems with regard to HUR stability of the CFrDDE on bounded and unbounded intervals. The method of the proofs is based on the fixed point approach.

Discrete-time adaptive control of robot manipulators [PDF]
A discrete-time model reference adaptive control scheme is developed for trajectory tracking of robot manipulators. Hyperstability theory is utilized to derive the adaptation laws for the controller gain matrices.

IET Electric Power Applications, Volume 18, Issue 12, Page 1730-1739, December 2024.When using model reference adaptive systems‐based parameter identification methods for sliding mode observer‐based sensorless control of permanent magnet synchronous motor, it is usually need to assumed that the rotor position estimation error is zero, but this error cannot be ignored in reality.

Synergies between price and life history enhance extinction risk in open‐access fisheries
Fish and Fisheries, Volume 25, Issue 6, Page 972-984, November 2024.Abstract There have been few documented extinctions of fished species, but many bioeconomic models predict that open‐access incentives make extinction possible. Open‐access multi‐species fisheries can cause species' extinction if other, faster‐growing species maintain profits at fatal effort levels.

On hyperstability of Cauchy functional equation in (2, γ )-Banach spaces
, 2020 In this paper, we generalize the recent hyperstability results obtained by Brzd ↪ ek and concerning the Cauchy functional equation f(x1 + x2) = f(x1) + f(x2). The obtained results are in (2,γ)-Banach spaces.

An assessment of potential interventions to reduce the totoaba illegal trade market
Conservation Biology, Volume 38, Issue 5, October 2024.Abstract The illegal trade in totoaba (Totoaba macdonaldi) is causing adverse social, ecological, and economic impacts. This illegal activity is accelerating the overexploitation of totoaba and pushing the critically endangered vaquita (Phocoena sinus) closer to extinction.

Catch uncertainty and recreational fishing attraction: Propositions and future research directions
Fish and Fisheries, Volume 25, Issue 5, Page 761-780, September 2024.Abstract Why do people fish for recreation? Social science literature suggests that both catch (e.g., number or sizes of fish) and non‐catch dimensions (e.g., nature experience, temporary escape) play a role. After reviewing the literature from environmental psychology, neuroscience, anthropology, recreational fisher motivation research as well as ...

A survey of adaptive control technology in robotics [PDF]
Previous work on the adaptive control of robotic systems is reviewed. Although the field is relatively new and does not yet represent a mature discipline, considerable attention has been given to the design of sophisticated robot controllers.
