Microscale Mapping of Fiber Strain and Damage in Composite Wrinkled Laminates Using Computed Tomography Assisted Wide‐Angle X‐Ray Scattering

open access: yesAdvanced Science, EarlyView.
This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...

Phase Diagrams and Piezoelectric Properties of Wurtzite Al1−x−yScxGdyN Heterostructural Alloys

open access: yesAdvanced Science, EarlyView.
This study demonstrates ferroelectricity and piezoelectric properties improvement of quaternary wurtzite Al1−x−yScxGdyN${\rm Al}_{1-x-y}{\rm Sc}_x{\rm Gd}_y{\rm N}$ films, guided by density functional theory calculations. Wurtzite Al1−x−yScxGdyN${\rm Al}_{1-x-y}{\rm Sc}_x{\rm Gd}_y{\rm N}$ films have a high optical bandgap, enhanced piezoelectric ...

High-order allpass cascade-connected phase-system design utilizing fractional polynomial errors

open access: yesJournal of Information and Telecommunication
This paper proposes a nonlinear optimization method for designing a high-order recursive allpass digital phase system that comprises several cascade-connected second-order (SO) allpass sections. This method first splits a given phase design specification

A Fully Polynomial (3/2 + ∈)-Approximation for Scheduling Monotone Moldable Jobs

open access: yes, 2016
A moldable job is a job that can be executed on an arbitrary number of processors, and whose processing time depends on the number of processors allotted to it. We consider the problem of scheduling monotone moldable jobs to minimize the makespan.

Enhancing Maturation of Human Neuromuscular Organoids via Electrical Stimulation

open access: yesAdvanced Science, EarlyView.
A framework for on‐demand and non‐invasive exposure of human neuromuscular organoids (NMOs) to electrical stimuli is established to promote their maturation. The robustness and effectiveness of different stimulation regimes are evaluated via thorough characterization of organoid tissue structure and contraction capacity. Chronic electrical stimulation,

Tak Zwanej Aproksymacji Jednokrotnie Optymalnej i Niektórych Jej Zastosowaniach w Mechanice

open access: yesEngineering Transactions, 1963
The Tchebyshev approximation called also the best or optimum approximation shows, in addition to the principal advantage of minimizing the approximation error in a certain interval, a few draw-backs from the practical viewpoint.
