Helmholtz decomposition theorem and Blumenthal's extension by regularization [PDF]

open access: yesCondensed Matter Physics, 2017
Helmholtz decomposition theorem for vector fields is usually presented with too strong restrictions on the fields and only for time independent fields.

Phase Mask Pinholes as Spatial Filters for Laser Interference Lithography

open access: yesAdvanced Photonics Research, 2023
Laser resonators have outputs with Gaussian spatial beam profiles. In laser interference lithography (LIL), using such Gaussian‐shaped beams leads to an inhomogeneous exposure of the substrate. As a result, dimensions of lithography‐defined features vary

An American Investor in the Theatre Industry of Budapest

open access: yesHistorical Studies on Central Europe, 2022
In the interwar period, an American theatre and film entrepreneur had a determinant impact on the private theatre sector of Budapest. Ben Blumenthal (1883–1967) ran the Vígszínház (Comedy Theatre) in 1920–1926 and owned its building in 1920–1949.

Interpretable failure risk assessment for continuous production processes based on association rule mining

open access: yesAdvances in Industrial and Manufacturing Engineering, 2022
Continuous production processes are often highly complex and involve machine failures as well as unscheduled process downtimes. Failures result in the production of waste and in high opportunity costs, but their causes are not always apparent to machine ...

Kinematic draping simulation optimization of a composite B-pillar geometry using particle swarm optimization

open access: yesHeliyon, 2022
The present work presents an algorithmic approach to determine the optimal starting point for any complex geometry draping processes. The time-efficient Kinematic Draping Simulation (KDS) is used to assess the drapability of a geometry depending on many ...

4D Textiles Made by Additive Manufacturing on Pre-Stressed Textiles—An Overview

open access: yesActuators, 2021
Four-dimensional textiles are textiles that can change shape or function over time by the influence of a stimulus, mainly force and heat. In this review, the focus is on 4D textiles made by additive manufacturing which is built on the concept of 4D ...

Scottish Common Sense and Nineteenth-Century American Law: A Critical Appraisal [PDF]

open access: yes, 2008
One overriding concern I have with Susanna Blumenthal\u27s insightful and stimulating article, The Mind of a Moral Agent: Scottish Common Sense and the Problem of Responsibility in Nineteenth-Century American Law, is whether there is anything ...

Dark Matter Contraction and the Stellar Content of Massive Early-type Galaxies: Disfavoring "Light" Initial Mass Functions [PDF]

open access: yes, 2010
We use stellar dynamics, strong lensing, stellar population synthesis models, and weak lensing shear measurements to constrain the dark matter (DM) profile and stellar mass in a sample of 53 massive early-type galaxies.

Analysis of Fibre Cross-Coupling Mechanisms in Fibre-Optical Force Sensors

open access: yesSensors, 2021
The force-enhanced light coupling between two optical fibres is investigated for the application in a pressure or force sensor, which can be arranged into arrays and integrated into textile surfaces.
