Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

open access: yesAdvanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

The Theoretical Substantiation of Cost Accounting in the Light of Conflicting Approaches [PDF]

open access: yes
Desde hace algunos años se viene sosteniendo en Alemania una discusión acerca de la fundamentación teórica de la contabilidad de costes, así como de la necesidad de mantener un sistema de costes independiente. El abanico de planteamientos posibles abarca

Theoretical calculation of the heat of formation of fulvene

open access: yes, 2008
The experimental value for the heat of formation of fulvene is 53.6 or 53.5 kcal mol(-1) depending on the source. However, no theoretical calculation seems to reproduce that value.

Experimental Evaluation of 100Cr6 Steel Microindented Surfaces Under Lubricated Nonconformal Point Contacts

open access: yesAdvanced Engineering Materials, EarlyView.
The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Numerical Analysis of Performance, Rotor Temperature Distributions, and Rotor Thermal Deformation of an R134a Screw Compressor

open access: yes, 2012
A numerical analysis is performed to systematically calculate the performance, rotor temperature distributions, and rotor thermal deformation of an R134a screw compressor. The analysis procedure includes three major steps.

Planar Solid‐State Nanopores Toward Scalable Nanofluidic Integration Based on CMOS Technology

open access: yesAdvanced Engineering Materials, EarlyView.
We present a scalable silicon‐based fabrication strategy for planar solid‐state nanopores to enable their integration with complex nanofluidic systems. Prototype devices demonstrate normal voltage‐current characteristics, good noise performance, and appreciable streaming currents. Our CMOS‐compatible fabrication process offers precise geometric control
