Discrete-Time Biomedical Signal Encryption [PDF]
Memoirs of the Scientific Sections of the Romanian Academy, 2017 Chaotic modulation is a strong method of improving communication security. Analog and discrete chaotic systems are presented in actual literature. Due to the expansion of digital communication, discrete-time systems become more efficient and closer to ...

Nonlinear waves in Newton's cradle and the discrete p-Schroedinger equation
, 2010 We study nonlinear waves in Newton's cradle, a classical mechanical system consisting of a chain of beads attached to linear pendula and interacting nonlinearly via Hertz's contact forces.

Modules Over an Incomplete Discrete Valuation Ring [PDF]
Proceedings of the American Mathematical Society, 1968 Throughout this note R will denote a discrete valuation ring with unique prime ideal (p) ==Rp. Q will denote the quotient field of R and R* will denote the completion of R. For basic definitions related to R-modules see [1], [2], or [5]. By rank, we shall mean torsion-free rank. If M is an R-module and xEM, UM(x) will denote the Ulm sequence (ao, al, *

IEEE transactions on power electronics, 2018 For dc–dc converters with pulsating output current, such as boost and buck–boost converters, the use of leading-edge or trailing-edge pulse width modulation (PWM) can result in distinctly different behavior. This phenomenon is not readily captured by the

Advanced Functional Materials, EarlyView.Cephalopod‐inspired photonic microparticles with dynamic structural coloration are fabricated via confined self‐assembly of linear block copolymers into ellipsoids containing stacked lamellae. Embedded superparamagnetic nanoparticles enable rapid magnetic alignment, restoring vivid, angle‐dependent color.

Discrete Wavelet Multi-Tone Transmission for Digital Subscriber Line
Journal of Engineering and Sustainable Development, 2005 Multi-Carrier Modulation (MCM) is an attractive technique for copper wire access technology in high-performance communication networks (e.g. Asymmetric and Very-high-rate Digital Subscriber Line). In digital implementations of MCM, subcarrier generation

Capacity Outer Bound and Degrees of Freedom of Wiener Phase Noise Channels with Oversampling
, 2017 The discrete-time Wiener phase noise channel with an integrate-and-dump multi-sample receiver is studied. A novel outer bound on the capacity with an average input power constraint is derived as a function of the oversampling factor. This outer bound

Advanced Functional Materials, EarlyView.Bioprosthetic aortic valves have revolutionized the treatment of aortic stenosis, but their durability is limited by structural valve deterioration (SVD). This review focuses on the pericardial tissue at the heart of these valves, examining how its mechanical properties and calcification drive fatigue and failure.
