Enginyeria gràfica bombí de porta

, 2022
Diseny gràfic d'un bombí de seguretat de gruix estàndard amb clau tipus dent de serra per a qualsevol porta. Els bombins de les portes són mecanismes que treballen amb força mecànica provocada per l’usuari, persona que es disposa a obrir una porta, de manera que al introduir la clau dins d'un rotor que es troba fixat dins d’una carcassa a mesura, fa ...

Machine learning in solid mechanics: Application to acoustic metamaterial design

International Journal for Numerical Methods in Engineering, Volume 125, Issue 14, 30 July 2024.
Abstract Machine learning (ML) and Deep learning (DL) are increasingly pivotal in the design of advanced metamaterials, seamlessly integrated with material or topology optimization. Their intrinsic capability to predict and interconnect material properties across vast design spaces, often computationally prohibitive for conventional methods, has led to

Reliability Assessment of Optical Physical Unclonable Functions Based on the Spatial Distribution of Catastrophic Failure Sites in MIM Structures

IEEE Access
Catastrophic failure sites, also referred to as breakdown spots, in Metal-Insulator-Semiconductor (MIS) and Metal-Insulator-Metal (MIM) structures are the consequence of the formation of conducting paths across the thin oxide film that separates the ...

Influencia de la temperatura en las propiedades a tracción de un acero inoxidable superdúplex

Revista de Metalurgia, 2001
Un acero inoxidable superduplex tipo EN 1.4410 se ensayó a tracción en el rango de temperaturas de 275 a 475 °C. La evolución, en función de la temperatura, de los valores de límite elástico y resistencia máxima indica la existencia de un fenómeno de ...

High-momentum dynamic structure function of liquid 3He-4He mixtures: a microscopic approach [PDF]

, 2000
The high-momentum dynamic structure function of liquid 3He-4He mixtures has been studied introducing final state effects. Corrections to the impulse approximation have been included using a generalized Gersch-Rodriguez theory that properly takes into ...

Enhanced Selective Contact Behavior in a‐Si:H/oxide Transparent Photovoltaic Devices via Dipole Layer Integration

Solar RRL, Volume 8, Issue 14, July 2024.
Herein, ultrathin a‐Si:H/oxide transparent photovoltaic devices are presented with notable improvement in efficiency given by a strong increase in open‐circuit voltage (Voc) thanks to the addition of dipolar interfacial layers at the electron‐transport layer based on poly(amidoamine) and polyethyleneimine.
