Dry metal forming of high alloy steel using laser generated aluminum bronze tools
MATEC Web of Conferences, 2015 Regarding the optimization of forming technology in economic and environmental aspects, avoiding lubricants is an approach to realize the vision of a new green technology. The resulting direct contact between the tool and the sheet in non-lubricated deep

StereoSet: Measuring stereotypical bias in pretrained language models [PDF]
Annual Meeting of the Association for Computational Linguistics, 2020 A stereotype is an over-generalized belief about a particular group of people, e.g., Asians are good at math or African Americans are athletic. Such beliefs (biases) are known to hurt target groups.

Journal of Epidemiology & Community Health, 2004 The concept of bias is the lack of internal validity or incorrect assessment of the association between an exposure and an effect in the target population in which the statistic estimated has an expectation that does not equal the true value. Biases can be classified by the research stage in which they occur or by the direction of change in a estimate.

Bioinform., 2003 MOTIVATION When running experiments that involve multiple high density oligonucleotide arrays, it is important to remove sources of variation between arrays of non-biological origin. Normalization is a process for reducing this variation. It is common to

The Bias in researching cognitive bias [PDF]
Advances in Health Sciences Education, 2014 The two problems are mathematically and formally equivalent. As Daniel Kahneman, the Nobel prize winning psychologist explains in his book, Thinking Fast and Slow (2012), if the probability of being a bank teller/having a pneumothorax is p(A), and the probability of being a feminist/having a ruptured spleen is p(B), then the probability of having both ...

The home bias and the local bias: A survey [PDF]
Management Review Quarterly, 2020 AbstractThe home bias like the disposition effect is a well-researched economic phenomenon in investor behaviour which has been examined in finance journal articles for decades. While there is little doubt about the existence of the bias, its magnitude varies across countries and investor groups.

Surface accuracy achieved by upsetting of preforms generated by laser rod end melting
MATEC Web of Conferences, 2015 Cold forming generally allows the reproduction of parts with a high production rate and low waste of material. For this reason, many small parts for example of the body of a smartphone undergo at least one forming operation during their fabrication, e.g.
