Productivity‐Driven Optimization of Laser Powder Bed Fusion Parameters for IN718 Superalloy: Process Control, Microstructure, and Mechanical Properties

open access: yesAdvanced Engineering Materials, EarlyView.
This study demonstrates how optimizing laser power, scanning speed, and hatching distance in laser powder bed fusion can boost the productivity of Inconel 718 manufacturing by up to 29% while maintaining mechanical integrity. The work delivers a validated process window and cost–time analysis, offering industry‐ready guidelines for efficient additive ...

La périurbanisation renforce-t-elle la ségrégation résidentielle urbaine en France ?

open access: yesEspace populations sociétés, 2009
This paper aims at assessing the effects of urban sprawl (urban spread or periurbanization) on socio-spatial inequalities within French cities. The recent literature linking urban spread and segregation highlights that the former may be an important ...

Field Report from Collaborative Research Center 1625: Heterogeneous Research Data Management Using Ontology Representations

open access: yesAdvanced Engineering Materials, EarlyView.
A unified research data management framework for heterogeneous materials data is presented. The system integrates multimodal datasets using ontologies and knowledge graphs, enabling interoperability and FAIR (findable, accessible, interoperable, reusable) data principles. By linking data across scales and workflows, it supports reproducible, Artifitial

GENDER SEGREGATION: FROM BIRTH TO OCCUPATION [PDF]

open access: yes
This paper offers a framework to study the gender segregation induced, not only by occupational choices among the employed population, but also by human capital characteristics and labor market participation decisions in the population consisting of non ...

Social segregation in secondary schools: how does England compare with other countries? [PDF]

open access: yes, 2006
We provide new evidence about the degree of social segregation in England's secondary schools, employing a cross-national perspective. Analysis is based on data for 27 rich industrialised countries from the 2000 and 2003 rounds of the Programme of ...

Creating Ti–Fe α/β Alloys by Diffusion‐Driven Solid‐State Processing

open access: yesAdvanced Engineering Materials, EarlyView.
This study proposes making alloys containing fast diffusing elements that are difficult to produce by ingot metallurgy, by diffusion‐driven solid‐state HIP processing of elemental powders and low‐temperature homogenisation. Here, novel Fe‐Ti α–β alloys are formed having fine α–β lamellae, a small β prior grain size without significant intermetallics ...

Measuring social segregation between London’s secondary schools, 2003 – 2008/9 [PDF]

open access: yes
Segregation is a spatial outcome of spatial processes that therefore needs to be measured spatially. This is the axiom from which local indices of segregation are developed and applied to the local markets within which schools compete.

A Simplified Laminar Flow Model for the Pultrusion of Glass Fiber/Polyethylene Terephthalate Commingled Yarns

open access: yesAdvanced Engineering Materials, EarlyView.
A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,
