Chaos in the BMN matrix model [PDF]

open access: yes, 2015
We study classical chaotic motions in the Berenstein-Maldacena-Nastase (BMN) matrix model. For this purpose, it is convenient to focus upon a reduced system composed of two-coupled anharmonic oscillators by supposing an ansatz. We examine three ans\"atze:

Clinical Practice Guideline for Evaluation and Management of Peripheral Nervous System Manifestations in Sjögren's Disease

open access: yesArthritis Care &Research, EarlyView.
Objective Sjögren's disease is an autoimmune disorder that can impact multiple organ systems, including the peripheral nervous system (PNS). PNS manifestations, which can exist concurrently, include mononeuropathies, polyneuropathies, and autonomic nervous system neuropathies.

Martelli Chaotic Properties of a Generalized Form of Zadeh’s Extension Principle

open access: yesJournal of Applied Mathematics, 2014
Let X denote a compact metric space and let f : X→X be a continuous map. It is known that a discrete dynamical system (X,f) naturally induces its fuzzified counterpart, that is, a discrete dynamical system on the space of fuzzy compact subsets of X.

Tensor models and 3-ary algebras

open access: yes, 2011
Tensor models are the generalization of matrix models, and are studied as models of quantum gravity in general dimensions. In this paper, I discuss the algebraic structure in the fuzzy space interpretation of the tensor models which have a tensor with ...

Current Tracking Adaptive Control of Brushless DC Motors

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
In this paper, the current tracking for Brushless Direct Current motors is approached considering uncertainty in the parameters of the motor's model. An adaptive control scheme to compensate electrical parameters uncertainty is proposed without requiring any knowledge of the mechanical parameters.

Linear/Nonlinear Active Disturbance Rejection Switching Control for Near-Space Morphing Vehicles Based on Type-2 Fuzzy Logic System

open access: yesApplied Sciences, 2023
This paper is concerned with the problems of robust switching control for near-space morphing vehicles (NMVs) with a large range of parameter uncertainty and external disturbance.

Selective and Precise Editing of Digital Polymers Through Parallel or Series Toehold‐Mediated Strand Displacement

open access: yesAdvanced Functional Materials, EarlyView.
A sequence‐encoded supramolecular construct containing two accessible toeholds is developed herein for enabling multiple editing operations. By introducing specific input strands, it is possible to selectively erase or rewrite digital content through parallel or series toehold‐mediated strand displacement (PTMSD or STMSD).

RANDOMLY GENERATED FUZZY DISCRETE DYNAMICAL SYSTEMS [PDF]

open access: yesFiabilitate şi Durabilitate
This paper aims to introduce the concept of a fuzzy discrete dynamical system as a fuzzy subgroupoid of X×Z×X, with Z representing the group of integer numbers.

Hybrid fuzzy sliding mode control for motorised space tether spin-up when coupled with axial and torsional oscillation [PDF]

open access: yes, 2010
A specialised hybrid controller is applied to the control of a motorised space tether spin-up space coupled with an axial and a torsional oscillation phenomenon.
