Effect of Current on Segregation and Inclusions Characteristics of Dual Alloy Ingot Processed by Electroslag Remelting

open access: yesHigh Temperature Materials and Processes, 2019
Three dual alloy ingots were processed by electroslag remelting with 1500 A, 1800 A and 2100 A. The compositions and inclusions of ingots were analyzed by means of various analytical techniques.

Auditory Stream Segregation Can Be Modeled by Neural Competition in Cochlear Implant Listeners

open access: yesFrontiers in Computational Neuroscience, 2019
Auditory stream segregation is a perceptual process by which the human auditory system groups sounds from different sources into perceptually meaningful elements (e.g., a voice or a melody). The perceptual segregation of sounds is important, for example,

Recent trends in occupational segregation by gender: a look across the Atlantic [PDF]

open access: yes, 2002
In this paper, we analyse the recent patterns of occupational segregation by gender in the EU countries vis-á-vis the US. Given the lack of long time-series data on homogeneous LFS data about occupations and educational attainments for male and female ...

Investigating the Effects of Build Height on Mechanical Behavior of Large‐Scale Laser Wire Directed Energy Deposited Nickel Titanium Alloy

open access: yesAdvanced Engineering Materials, EarlyView.
Laser wire directed energy deposition process was leveraged to fabricate large scale NiTi alloy wall. Evaluation of build‐height‐dependent tribo‐mechanical properties revealed significant differences in location specific sample characteristics. The middle region achieved optimal performance (superior wear resistance, balanced strength‐ductility ...

Demonstrating How to Best Examine Group-based Segregation: A Statistical and Conceptual Multilevel Approach

open access: yesMethoden, Daten, Analysen, 2018
Segregation between ethnic or sociodemographic groups represents a longstanding key independent and dependent variable for the social sciences. However, researchers have only recently begun to take advantage of inferential rather than descriptive ...

Kinematic Segregation of Flowing Grains in Sandpiles

open access: yes, 1998
We study the segregation of granular mixtures in two-dimensional silos using a set of coupled equations for surface flows of grains. We study the thick flow regime, where the grains are segregated in the rolling phase.

Interactions between Molten High‐Silicon Electrical Steels and Carbon‐Bonded MgO Refractories Based on Recyclates

open access: yesAdvanced Engineering Materials, EarlyView.
This study examines how several molten high‐silicon electrical steels interact with both conventional and recycled MgO–C refractories. For this, various immersion experiments are conducted. In addition to infiltration, a number of mechanisms are identified and explained that control the corrosion of the refractory material.

Bordering the area of spatial relevance for schools: a stochastic network approach using the example of Hamburg, Germany

open access: yesBelgeo, 2017
Most approaches to spatial definitions of schooling markets are based on assumptions which may cause incorrect estimates. This paper presents stochastic network analysis as an alternative approach.

Enhanced Oxidation and Thermal Shock Resistance of N‐type Mg2Si0.89(Sn0.1,Sb0.01) Thermoelectric Material via Cr0.9Si0.1 Coating

open access: yesAdvanced Engineering Materials, EarlyView.
Cr0.9Si0.1 protective coatings are developed to enhance the thermal‐shock and oxidation resistance of Mg2Si0.89(Sn0.1,Sb0.01) thermoelectric (TE) materials. The coating forms a dense and adherent barrier that suppresses oxygen diffusion and mitigates mechanical degradation during cyclic oxidation, demonstrating its potential to improve the long‐term ...

“The Tenth Talented” v. “The Hundredth Talented”: W. E .B. Du Bois’s Two Versions on the Leadership of the African American Community in the 20th Century

open access: yesAmerican, British and Canadian Studies Journal, 2012
Comparing two essays written by Du Bois at a great interval of time, “The Tenth Talented” (1903) and “The Hundredth Talented” or the “Guiding Hundredth” (1948), the author of this article intends to deal with Du Bois’s endeavor to cohere culturally and ...
