Efficiency of the Needle Probe Test for Evaluation of Thermal Conductivity of Composite Materials: Two-Scale Analysis

open access: yesStudia Geotechnica et Mechanica, 2014
The needle probe test, as a thermal conductivity measurement method, has become very popular in recent years. In the present study, the efficiency of this methodology, for the case of composite materials, is investigated based on the numerical ...

Detection of polarized quasi-periodic microstructure emission in millisecond pulsars [PDF]

open access: yes, 2016
Microstructure emission, involving short time scale, often quasi-periodic, intensity fluctuations in subpulse emission, is well known in normal period pulsars. In this letter, we present the first detections of quasi-periodic microstructure emission from

Fabrication of periodic microstructures for improving light-extraction efficiencies of light-emitting ZnO/Si devices

open access: yesResults in Physics, 2017
This article presents the first demonstration of integrating a simple one-dimensional (1-D) periodic microstructure and a light-emitting zinc oxide (ZnO) thin film on a silicon (Si) substrate using a simple process with two-beam interference lithography ...

An interface-oriented data-driven scheme applying into eutectic patterns evolution

open access: yesMaterials & Design, 2022
Solid-liquid interface dynamics plays a crucial role in microstructure evolution during solidification. However, it is difficult to extract sufficient spatial information to describe the variation in the irregular and non-periodic solid-liquid interface ...

A modular framework to obtain representative microstructural cells of additively manufactured parts

open access: yesJournal of Materials Research and Technology, 2022
The repeating nature of additive manufacturing (AM) translates into quasi-periodic repeating hierarchical microstructures, which vary depending on the working principle of the AM technology.

Observational Evidence for Persistent Microstructure Periodicities [PDF]

open access: yesInternational Astronomical Union Colloquium, 1992
AbstractBy using Cross Spectral Density processing between high time resolution radio intensity observations of pulsars made simultaneously at two different receiver frequencies, several high frequency periodicities that are persistent over many pulses were discovered. A possible interpretation in terms of neutron star vibration models is discussed.

Strayfield calculation for micromagnetic simulations using true periodic boundary conditions

open access: yesScientific Reports, 2021
We present methods for calculating the strayfield in finite element and finite difference micromagnetic simulations using true periodic boundary conditions. In contrast to pseudo periodic boundary conditions, which are widely used in micromagnetic codes,
