Influence of the Wire Feeding on the Wetting Process during Laser Brazing of Aluminum Alloys with Aluminum-Based Braze Material

open access: yesJournal of Manufacturing and Materials Processing, 2019
The wetting behavior in laser brazing can be designated as inconstant, caused largely by external process discontinuities such as the wire feeding. To reveal periodic melt pool propagation effects that occur during laser brazing of aluminum and for a ...

The Role of Response Bias in Perceptual Learning [PDF]

open access: yes, 2015
Sensory judgments improve with practice. Such perceptual learning is often thought to reflect an increase in perceptual sensitivity. However, it may also represent a decrease in response bias, with unpracticed observers acting in part on a priori hunches

Giant exchange bias in a single-phase magnet with two magnetic sublattices

open access: yes, 2013
Exchange bias phenomenon is generally ascribed to the exchange coupling at the interfaces between ferromagnetic and antiferromagnetic layers. Here, we propose a bulk form of exchange bias in a single-phase magnet where the coupling between two magnetic ...

Bias deconstructed: Unravelling the scale dependence of halo bias using real space measurements [PDF]

open access: yes, 2013
We explore the scale dependence of halo bias using real space cross-correlation measurements in N-body simulations and in Pinocchio, an algorithm based on Lagrangian Perturbation Theory. Recent work has shown how to interpret such real space measurements

Bias in the use of evidence for policy: 'technical bias' and 'issue bias' [PDF]

open access: yes, 2016
Advocates of evidence-based policymaking (EBP) often argue that policy decisions are improved when they are informed by rigorous and accurate scientific evidence. However, some critical authors argue that public policies cannot be decided on technical evidence alone.

OPTIMIZING THE USE OF TRAFFIC LIGHTS ON THE EXAMPLE OF MOSCOW

open access: yesСтатистика и экономика, 2016
Presence of traffic on the road makes an imbalance in traffic. In a modern city suchas Moscow, not do without them, but the need for their use is not always justifi ed, as there moments during the day, when their presence is not appropriate and just goesto ...

ANALISIS TERHADAP HUBUNGAN ANTARA KONVERGENSI INTERNATIONAL FINANCIAL REPORTING STANDAR (IFRS), MANAJEMEN LABA DAN KUALITAS AUDIT (Studi Empiris pada Industri Properti dan Real Estat yang Terdaftar di Bursa Efek Indonesia Tahun 2007 dan 2013) [PDF]

open access: yes, 2015
This study aimed to examine the relationship between the convergence of IFRS , earnings management and audit quality. Based on the research of Van Tendeloo and Vanstraelen (2005), proposed that audit quality may be associated between the convergence of ...

To Bias or Not to Bias: Detecting bias in News with bias-detector

open access: yes
Media bias detection is a critical task in ensuring fair and balanced information dissemination, yet it remains challenging due to the subjectivity of bias and the scarcity of high-quality annotated data. In this work, we perform sentence-level bias classification by fine-tuning a RoBERTa-based model on the expert-annotated BABE dataset.

Selection Bias, Confounding, or Information Bias? [PDF]

open access: yesHypertension, 2007
To the Editor, As a public health advocate against tobacco use, I find the recent article by Jatoi et al1 interesting and quite informative. As an epidemiologist, I also have a few concerns surrounding the methodologic issues of such study findings. One of the most essential components of a comprehensive tobacco control program is to disseminate the ...

Dynamic Process Behavior in Laser Chemical Micro Machining of Metals

open access: yesJournal of Manufacturing and Materials Processing, 2018
Laser chemical machining (LCM) is a non-conventional processing method that enables a smooth and precise micro structuring of metallic surfaces. However, a high-quality removal is limited to a laser power window of some 100 mW.
