Reducing the use of Fossil Carbon and Fuels to Defossilize the Electric Steelmaking Route: Evaluation of the Effects of Alternative C‐Bearing Materials and Hydrogen in the Electric Arc Furnace

open access: yessteel research international, EarlyView.
The experiments and simulations demonstrate that, in general, alternative carbon sources can decrease fossil CO2 without adversely impacting EAF process and product. High plastics and tires ratios cause unsafe conditions and poor slag foaming. Hydrogen in EAF burners decreases CO2 but increases water vapor, which can raise the hydrogen content in ...

Explainable artificial intelligence (XAI)‐powered design framework for lightweight strain‐hardening ultra‐high‐performance composites (SH‐UHPC)

open access: yesStructural Concrete, EarlyView.
Abstract Lightweight strain‐hardening ultra‐high‐performance concrete composite (SH‐UHPC) is an outstanding alternative for engineering applications and infrastructure thanks to its outstanding strength, toughness, ductility, and low density. The integration of artificial intelligence (AI)‐based modeling strategies into engineering problems can ...

La inexcusable tasca de confeccionar mapes

open access: yesTreballs de la Societat Catalana de Geografia, 1991
Amb Salvador Llobet m'uní una bona amistat i una preocupació naturalística comú. L'oportunitat que se m'ofereix de retre homenatge a la seva memòria en aquestes pàgines, que molt agraeixo, em porta a recordar algunes preocupacions comunes. L'ecologia té molts problemes paral·lels i comparteix arrels amb certes maneres d'entendre la geografia física i ...

A Dynamic Correlation‐Information‐Fusion‐Based Spatiotemporal Network for Traffic Flow Forecasting

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Traffic Flow Forecasting (TFF) is a foundational task in the development of Intelligent Transport Systems (ITSs). The primary challenge is to undertake a comprehensive exploration of the intrinsic dynamic spatiotemporal correlations of the road network, unveiling the long‐term evolutionary traffic trends.

Enumeració de mapes planaris

open access: yes, 2020
Al llarg d'aquest treball s'estudiarà l'enumeració dels mapes planaris arrelats i mapes planaris arrelats bipartits amb n arestes a partir del mètode simbòlic i mètode quadràtic introduït per Tutte. A més, aquests dos resultats serviran per construir bijeccions per comptar el nombre de quadrangulacions arrelades amb n cares, mapes planaris arrelats ...

A Novel Converter Transformer DAM‐LSTNet Vibration Generation Model for Data Imbalance Identification

open access: yesHigh Voltage, EarlyView.
ABSTRACT Converter transformer vibration failures, primarily because of winding and core vibrations, severely impact the safe operation of high voltage direct current (HVDC) systems. These vibrations are influenced by voltage and current, and are transmitted through transformer oil and structural components to the tank. Current numerical models fail to

Explainable spatial machine learning for hedonic real estate modeling

open access: yesReal Estate Economics, EarlyView.
Abstract Accurately modeling rents and prices is a key challenge in real estate analysis. Traditional linear models may fail to capture complex non‐linear relationships, and spatial dependencies are often ignored in existing machine‐learning approaches.
