Labor-capital relations in the construction sector in Poland [PDF]

open access: yesUrbanism. Arhitectura. Constructii, 2015
The aim of this paper is to estimate the Cobb-Douglas production function and the CES (constant elasticity of substitution) function for the construction sector in Poland. The period since 2002 is analyzed.

A Lightweight Procedural Layer for Hybrid Experimental–Computational Workflows in Materials Science

open access: yesAdvanced Engineering Materials, EarlyView.
We unveil a prototype hybrid‐workflow framework that fuses automatedcomputation with hands‐on experiments. Built atop pyiron, a lightweight, parameterized layer translates procedure descriptions into executable manual steps, syncing instrument settings, human interventions, and data capture in real‐time today.

A property of the H-convergence for elasticity in perforated domains

open access: yesElectronic Journal of Differential Equations, 2006
In this article, we obtain the $H_{e}^{0}$-convergence as a limit caseof the $H_{e}$-convergence. More precisely, if$Omega_{varepsilon}$ is a perforated domain with (admissible)holes $T_{varepsilon}$ and $chi_{varepsilon}$ denote itscharacteristic ...

Optimization of the Production of Rubber Compounds Using Mathematical Models

open access: yesAdvanced Engineering Materials, EarlyView.
Rubber compounds were mixed in a batch internal mixer, and symbolic regression was used to derive mathematical models linking recipe and process parameters to ram path, torque, and mixing quality (incorporation, dispersion, distribution). Subsequent optimization with evolutionary algorithms identified operating conditions that reduce specific energy ...

Ontology‐Aligned Structuring and Reuse of Multimodal Materials Data and Workflows Toward Automatic Reproduction

open access: yesAdvanced Engineering Materials, EarlyView.
Reproduction of stacking fault energy calculations from literature with a semi‐automated large language model‐assisted extraction procedure: extraction of simulation protocol, atomistic structures, computational parameters, and reported results, ontology alignment, knowledge graph construction and, finally, recomputation forvalidation.

Three-level stochastic optimization framework for energy management in smart grids with integrated peer-to-peer trading

open access: yesEnergy Conversion and Management: X
The integration of peer-to-peer (P2P) energy trading into distribution networks introduces complex coordination challenges among the distribution system operator (DSO), P2P market platform, and prosumers.

Fully Consistent Finite-Strain Landau Theory for High-Pressure Phase Transitions

open access: yesPhysical Review X, 2014
Landau theory (LT) is an indispensable cornerstone in the thermodynamic description of phase transitions. As with structural transitions, most applications require one to consistently take into account the role of strain.

Efficient Computation of Dynamic Stability Data with a Linearized Frequency Domain Solver. [PDF]

open access: yes, 2010
Determination of aeroelastic stability boundaries for full aircraft configu- rations by solving the time-accurate unsteady Reynolds-averaged Navier-Stokes (RANS) equations is recognized as extremely computationally expensive or impractical.

Comparison of Triply Periodic Minimal Surface Energy Absorbers Under Uniaxial Compressive Loading

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates LCD 3D printed Triply Periodic Minimal Surface (TPMS) structures as mechanical energy absorbers. By comparing various base designs and layered combinations under uniaxial compression, it identifies that a Diamond‐Gyroid sandwich structure offers superior performance.
