Laser Powder Bed Fusion of Copper–Tungsten Composites for Heat Sink Applications in High‐Power Electronics

open access: yesAdvanced Engineering Materials, EarlyView.
This article demonstrates the successful qualification of a copper–tungsten composite for laser powder bed fusion. The resulting components exhibited high density, high thermal conductivity, and reduced thermal expansion. Heat sinks with complex geometries were successfully manufactured, clearly showcasing the material's potential for additive ...

Language Development as a Change of the Parameter Pattern of the Language System

open access: yesПсихолінгвістика, 2018
The article advances linguistic synergetics as a novel research methodology by focusing on applicability of synergetic principles to language development studies. Synergetics is a name for the science of complexity that deals with principles of emergence,

Joint Detection of Structural Change and Nonstationarity in Autoregressions [PDF]

open access: yes
In this paper we develop a test of the joint null hypothesis of parameter stability and a unit root within an ADF style autoregressive specification whose entire parameter structure is potentially subject to a structural break at an unknown time period ...

Duplex Stainless Steel Laser‐Surface Textured: Stability in Brine Solution

open access: yesAdvanced Engineering Materials, EarlyView.
Controlled laser‐surface treatment (LST) of duplex DSS2205 steel is performed to increase its stability in brine solution under cyclic electrochemical assays. The superior protection with respect to flat and smooth panels is attributed to the presence of FeCr2O4 as the main protective oxide layer in the LST surface, after corrosion tests. The stability

A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions

open access: yesAdvanced Engineering Materials, EarlyView.
This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...

On large-sample estimation and testing via quadratic inference functions for correlated data [PDF]

open access: yes, 2005
Hansen (1982) proposed a class of "generalized method of moments" (GMMs) for estimating a vector of regression parameters from a set of score functions.

Multimodal Mechanical Testing of Additively Manufactured Ti6Al4V Lattice Structures: Compression, Bending, and Fatigue

open access: yesAdvanced Engineering Materials, EarlyView.
In this experimental study, the mechanical properties of additively manufactured Ti‐6Al‐4V lattice structures of different geometries are characterized using compression, four point bending and fatigue testing. While TPMS designs show superior fatigue resistance, SplitP and Honeycomb lattice structures combine high stiffness and strength. The resulting

The Interpretation of Null Subjects in a Radical Pro-drop Language: Topic Chains and Discourse-semantic Requirements in Chinese

open access: yesStudies in Chinese Linguistics, 2019
Based on original data collected through an online experiment, evidence is provided in this paper that the interpretation of null subjects in a radical pro-drop language like Chinese relies on the topic criterion proposed for consistent and partial pro ...
