Previsión de la demanda de una cadena de hornos de Barcelona utilizando modelos ARIMA

Pons Hardwick, Oscar-Lewis

2025Repository: UPCommons — Universitat Politècnica de Catalunya

Este trabajo presenta el desarrollo de una primera versión de un sistema de previsión de la demanda para una cadena de hornos de Barcelona, combinando el uso de modelos estadísticos ARIMAX y SARIMAX con una aplicación web desarrollada en Streamlit. El proyecto surge de la…

Fairness on ramp metering. Extending ALINEA for equitable access and congestion reduction

Zhan, Yangle

2025Repository: UPCommons — Universitat Politècnica de Catalunya

Ramp metering systems effectively reduce freeway congestion but often face public op- position due to inequitable delay distribution among users. This study addresses this challenge by introducing EqALINEA, a fairness-enhanced extension of the ALINEA algo- rithm designed to…

Clique factors in pseudorandom graphs

Morris, Patrick Wyndham

2025Repository: UPCommons — Universitat Politècnica de Catalunya

An n-vertex graph is said to to be (p,ß)-bijumbled if for any vertex sets A,B¿V(G), we have e(A,B)=p|A||B|±ß |A||B| ¿ . We prove that for any r¿N =3 ¿ and c>0 there exists an e>0 such that any n-vertex (p,ß)-bijumbled graph with n¿rN, p>0, d(G)=cpn and ß=ep r-1 n contains a K r…

Competing elastic and viscous gradients determine directional cell migration

Sáez Viñas, Pablo · Shirke, Pallavi Uday · Seth, Jyoti R. + 2 authors

2025Repository: UPCommons — Universitat Politècnica de Catalunya

Cell migration regulates central life processes including embryonic development, tissue regeneration, and tumor invasion. To establish the direction of migration, cells follow exogenous cues. Durotaxis, the directed cell migration towards elastic stiffness gradients, is the…

Evaluating the effectiveness of large language models in converting clinical data to FHIR format

Delaunay, Julien · Girbes, Daniel · Cusidó Roura, Jordi

2025Publisher: Multidisciplinary Digital Publishing InstituteRepository: UPCommons — Universitat Politècnica de Catalunya

The conversion of unstructured clinical data into structured formats, such as Fast Healthcare Interoperability Resources (FHIR), is a critical challenge in healthcare informatics. This study explores the potential of large language models (LLMs) to automate this conversion…
