Studies in Liocranidae (Araneae): a new afrotropical genus featuring a synapomorphy for the Cybaeodinae [PDF]

open access: yes, 2013
Cteniogaster, a new genus of small ground spiders is described from Kenya and Tanzania. It encompasses seven new species, three of which are known from both sexes: C. toxarchus sp. nov., the type species, C. conviva sp. nov. and C. hexomma sp. nov. Three

Probabilistic Bi-Level Assessment and Adaptive Control Mechanism for Two-Tank Interacting System

open access: yesIEEE Access, 2023
Liquid level control is a fundamental aspect employed across various industries, where the precise regulation of liquid levels and flow rates is of utmost importance. The Proportional-integral-derivative (PID)controller is widely employed but in practice,

Algorithms for adaptive control of two-arm flexible manipulators under uncertainty [PDF]

open access: yes, 1988
A nonlinear extension of model reference adaptive control (MRAC) technique is used to guide a double arm nonlinearizable robot manipulator with flexible links, driven by actuators collocated with joints subject to uncertain payload and inertia.

Force control of moving object using adaptive control

open access: yesNihon Kikai Gakkai ronbunshu, 2014
A pneumatic servo seems to be effectively applied to many varieties of gripping or compressing works, because its high compressibility is useful to the force control.

A High Soluble‐Fibre Allele in Wheat Encodes a Defective Cell Wall Peroxidase Responsible for Dimerization of Ferulate Moieties on Arabinoxylan

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Increasing dietary fibre (DF) intake is an important target to improve health. An attractive strategy for this is to increase DF in wheat which is derived principally from the endosperm cell wall polysaccharide arabinoxylan (AX). The water‐extractable form of this (WE‐AX) accounts for most soluble dietary fibre (SDF), which is believed to ...

Design of Novel Exponential PDN Controller via Quadratic Interpolation Optimiser for Nonlinear and Unstable Ball and Beam System

open access: yesIET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.
This study presents a novel exponential proportional‐derivative controller with filter (exp‐PDN) for stabilising the nonlinear and underactuated ball and beam system. Unlike conventional PID‐based approaches, the proposed controller removes the integral term, resulting in faster transient responses and improved robustness.

Performance Enhancement of MRAC via Generalized Dynamic Inversion

open access: yesActuators
Model Reference Adaptive Control (MRAC) guarantees closed loop stability and desired steady state performance of dynamical systems without undue dependence upon their mathematical models. However, the applicability of MRAC may not be suitable for systems
