Possibilities of Additive Technologies for the Manufacturing of Tooling from Corrosion-Resistant Steels in Order to Protect Parts Surfaces from Thermochemical Treatment

open access: yesMetals, 2021
The structure and physical–mechanical properties of products made from powders of corrosion-resistant steel 12X18H10T by the laser-beam powder bed fusion (LB-PBF) and subsequent ion-plasma nitriding in the work were investigated.

Chance-Constrained Efficiency Analysis [PDF]

open access: yes, 1990
Data envelopment analysis (DEA) is extended to the case of stochastic inputs and outputs through the use of chance-constrained programming. The chance-constrained envelope envelops a given set of observations "most of the time." We show that the chance ...

Evaluating the impact of input variables on thermal load estimation in office spaces using validated models

open access: yesAnales de Edificación
The design and optimisation of energy efficiency measures in buildings are often based on simulation models, which must be validated with experimental measurements to ensure a reliable representation of the building’s actual behaviour.

Photoinhibiting via simultaneous photoabsorption and free-radical reaction for high-fidelity light-based bioprinting

open access: yesNature Communications, 2023
Light-based 3D bioprinting is now employed widely to fabricate geometrically complex constructs for various biomedical applications. However, the inherent light scattering defect creates significant challenges in patterning dilute hydrogels to form high ...

Cooperative production and efficiency [PDF]

open access: yes, 2007
We characterize the sharing rule for which a contribution mechanism achieves efficiency in a cooperative production setting when agents are heterogeneous. The sharing rule bears no resemblance to those considered by the previous literature.
