How to empower Grünwald–Letnikov fractional difference equations with available initial condition?

open access: yesNonlinear Analysis, 2022
In this paper, the initial condition independence property of Grünwald–Letnikov fractional difference is revealed for the first time. For example, the solution x(k) of equation aG∇kαx(k) = f(x(k)),  k > a + 1, cannot be calculated with initial condition

Comparative Analysis among DSP and FPGA-based Control Capabilities in PWM Power Converters [PDF]

open access: yes, 2004
PWM power converters are close to be mature for standard diffusion. New FPGA technologies could now realise at best the digital control key-points: flexible performance and time to market.

Dynamical equilibration of topological properties [PDF]

open access: yesPhysical Review B, 2018
We study the dynamical process of equilibration of topological properties in quantum many-body systems undergoing a parameter quench between two topologically inequivalent Hamiltonians. This scenario is motivated by recent experiments on ultracold atomic gases, where a trivial initial state is prepared before the Hamiltonian is ramped into a ...

Improvement of Dynamic Performance and Detectivity in Near-Infrared Colloidal Quantum Dot Photodetectors by Incorporating Conjugated Polymers

open access: yesMolecules, 2022
Colloidal quantum dots (CQDs) have a unique advantage in realizing near-infrared (NIR) photodetection since their optical properties are readily tuned by the particle size, but CQD-based photodetectors (QPDs) presently show a high dark current density ...

Dynamic mechanical properties of oral mucosa: comparison with polymeric soft denture liners. [PDF]

open access: yes, 2011
The purpose of this work was to characterize the viscoelastic behaviour of oral mucosa and compare it with the dynamic mechanical properties of different soft liners. For this purpose, a sample of pig oral mucosa and six commercialized soft liner samples

Dynamic Properties and Vibration Control of Additively Manufactured Carbon and Glass Fiber Reinforced Polymer Composites Using MFC: A Numerical Study with Experimental Validation

open access: yesJournal of Manufacturing and Materials Processing
With the growing need for lightweight, durable, and high-performance structures, additively manufactured (AM) polymer composite structures have captured significant attention in the engineering community. These structures offer considerable advantages in

Static and dynamic properties of shell-shaped condensates [PDF]

open access: yes, 2018
Static, dynamic, and topological properties of hollow systems differ from those that are fully filled as a result of the presence of a boundary associated with an inner surface. Hollow Bose-Einstein condensates (BECs) naturally occur in various ultracold

MODELLING AND TESTING OF DYNAMIC PROPERTIES OF C0-45 TURBOCHARGERS [PDF]

open access: yesScientific Journal of Silesian University of Technology. Series Transport, 2017
The paper presents modelling process and results of the bench tests of the C0-45, which is a turbocharger for heavy-duty diesel engines. For turbochargers like this, it is necessary to measure the level of vibration.

Dynamic properties of screw-bolts connections of sowing machine

open access: yesPrzegląd Naukowy Inżynieria i Kształtowanie Środowiska, 2019
A vehicle is a complicated system under the influence of vibration caused by an inequality of the road surface, variable speed, unbalance of the rotating elements. The main factors influencing the relaxation of threaded connections (TC) are the amplitude,
