Monitoring and Maintaining Laser Surface Texture Quality Based on Acoustic and Optical Process Emissions during Direct Laser Interference Patterning

open access: yesAdvanced Engineering Materials, EarlyView.
Acoustic emissions during direct laser interference patterning are shown to strongly correlate with surface texture depth. By implementing a closed‐loop control system utilizing acoustic feedback, consistent microstructures with uniform depth are achieved despite laser power fluctuations.

On θ-regular spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1994
In this paper we study θ-regularity and its relations to other topological properties. We show that the concepts of θ-regularity (Janković, 1985) and point paracompactness (Boyte, 1973) coincide.

Initial λ-compactness in linearly ordered spaces [PDF]

open access: yesarXiv, 2013
We show that a linearly ordered topological space is initially \lambda-compact if and only if it is \lambda-bounded, that is, every set of cardinality $\leq \lambda$ has compact closure. As a consequence, every product of initially \lambda-compact linearly ordered topological spaces is initially \lambda-compact.

ALD‐Assisted VO2 for Memristor Application

open access: yesAdvanced Engineering Materials, EarlyView.
This work demonstrates a strategy for depositing VOx using thermal atomic layer deposition (ALD) followed by thermal annealing to synthesize VO2. The thin film and core/shell wire memristors exhibit excellent switching performance and are highly sensitive to ambient temperature.

Performance Analysis of Large-Scale Digital Phased Array Mixed-ADC Receiver in Compact Space

open access: yes天地一体化信息网络
In order to evaluate the performance of large-scale digital phased array mixed-ADC receivers under the influence of mutual coupling effects in compact spaces, a performance analysis method was proposed.

Measures on the Product of Compact Spaces [PDF]

open access: yesMonatshefte f�r Mathematik, 2002
If K is an uncountable metrizable compact space, we prove a ‘factorization’ result for a wide variety of vector valued Borel measures μ defined on Kn. This result essentially says that for every such measure μ there exists a measure μ0 defined on K such that the measure μ of a product A1 ו • •×An of Borel sets of K equals the measure μ0 of the ...

An Examination of Aerosol Jet‐Printed Surface Roughness and its Impact on the Performance of High‐Frequency Electronics

open access: yesAdvanced Engineering Materials, EarlyView.
This study explores aerosol jet‐printed (AJP) surface roughness, its effects on the performance of microwave electronics, and its process contributors. First, an electromagnetic model is vetted for AJP's unique roughness signature. Simulations are built which show process‐induced roughness is as significant as conductor resistivity in driving microwave

Slice Theorem For Differential Spaces And Reduction By Stages

open access: yesDemonstratio Mathematica, 2014
We show that the space P/G of orbits of a proper action of a Lie group G on a locally compact differential space P is a locally compact differential space with quotient topology.
