From Nanoindentation to Microhardness to Tensile Strength: Correlation Coefficients Estimates as a Function of Microstructure in Eutectic SnBi Alloy

open access: yesEngineering Reports, Volume 7, Issue 4, April 2025.
Our manuscript focuses on the correlation between nanohardness, microhardness, and macroscopic tensile strength—an area of increasing industrial demand, especially considering advent to miniaturization of all electronic components and non‐destructive testing. The material selected for this study stems from the microelectronic industry's pursuit of lead‐

THE GOODNESS OF SIMULTANEOUS FITS IN ISIS

open access: yesActa Polytechnica, 2016
In a previous work, we introduced a tool for analyzing multiple datasets simultaneously, which has been implemented into ISIS. This tool was used to fit many spectra of X-ray binaries.

Mixing of CNO-cycled matter in pulsationally and magnetically active massive stars [PDF]

open access: yes, 2010
We report on the abundances of helium, carbon, nitrogen and oxygen in a larger sample of Galactic massive stars of ~7-20 M_sun near the main sequence, composed of apparently normal objects, pulsators of beta-Cephei- and SPB-type, and magnetic stars.

Microstructure and mechanical properties of Al-1050 during incremental ECAP [PDF]

open access: yes, 2017
Incremental ECAP is a new method of ECAP process were the severe shear deformation is incrementally applied on the sample resulting in grain refining and new texture developing. The fundamental objective of the present work is an observation of effect of

Investigation of Mechanical and Corrosion Behavior of ECAP Processed AA7075 Through ML, ANNW, RSM, and SA Methodologies

open access: yesEngineering Reports, Volume 7, Issue 4, April 2025.
The impact of ECAP processing parameters on mechanical properties and corrosion behavior of AA7075 were discussed using experimental, ML, and RS methodologies. It was found that ECAP resulted in notable improvement in both mechanical and corrosion behavior for AA7075, which can be attributed to the significant grain refinement after processing ...

Simulating radio emission from air showers with CoREAS [PDF]

open access: yes, 2013
CoREAS is a Monte Carlo code for the simulation of radio emission from extensive air showers. It implements the endpoint formalism for the calculation of electromagnetic radiation directly in CORSIKA. As such, it is parameter-free, makes no assumptions on the emission mechanism for the radio signals, and takes into account the complete complexity of ...

Trapped charge dynamics in InAs nanowires

open access: yes, 2012
We study random telegraph noise in the conductance of InAs nanowire field-effect transistors due to single electron trapping in defects. The electron capture and emission times are measured as functions of temperature and gate voltage for individual ...

n-Opposition theory to structure debates [PDF]

open access: yesarXiv, 2009
2007 was the first international congress on the ?square of oppositions?. A first attempt to structure debate using n-opposition theory was presented along with the results of a first experiment on the web. Our proposal for this paper is to define relations between arguments through a structure of opposition (square of oppositions is one structure of ...

Assessment of competitiveness of power generating companies through a riskbased approach: a case study of developing economies [PDF]

open access: yes, 2016
The global financial crisis has shown that power companies are highly exposed to market risks. Market volatility creates competitive tension in the industry because the lack of the necessary methodological tools does not allow power companies to timely ...

Strain Rate Contribution due to Dynamic Recovery of Ultrafine-Grained Cu–Zr as Evidenced by Load Reductions during Quasi-Stationary Deformation at 0.5 Tm

open access: yesMetals, 2019
During quasi-stationary tensile deformation of ultrafine-grained Cu-0.2 mass%Zr at 673 K and a deformation rate of about 10−4 s−1 load changes were performed.
