  • Ordering dynamics of the multi-state voter model 

    Starnini, Michele; Baronchelli, Andrea; Pastor Satorras, Romualdo (Institute of Physics (IOP), 2012-10-30)
    Article
    Accés obert
    The voter model is a paradigm of ordering dynamics. At each time step, a random node is selected and copies the state of one of its neighbors. Traditionally, this state has been considered as a binary variable. Here, we ...

  • Relevance of backtracking paths in recurrent-state epidemic spreading on networks 

    Castellano, Claudio; Pastor Satorras, Romualdo (American Institute of Physics (AIP), 2018-11-27)
    Article
    Accés obert
    The understanding of epidemics on networks has greatly benefited from the recent application of message-passing approaches, which allow us to derive exact results for irreversible spreading (i.e., diseases with permanent ...

  • Study for the numerical resolution of the Navier-Stokes equations using the Fractional Step Method 

    Feliubadaló Rubio, Anna (Universitat Politècnica de Catalunya, 2018-06-10)
    Treball Final de Grau
    Accés obert
    This work is denominated Study for the numerical resolution of the Navier-Stokes equations using the Fractional Step Method. It is divided into 7 Chapters and 1 Annex. Chapter 1 presents the objectives, scope, requirements ...

  • Study of the development of automatic control systems for autonomous exploration robots 

    Balado Ordax, Ramiro; Balado (Universitat Politècnica de Catalunya, 2018-06)
    Treball Final de Grau
    Accés obert
    This thesis explores the necessities of autonomous exploration rovers within the context of a high latency communications link and proposes a program architecture made up of different modules which takes these necessities ...

  • Tuning the Kinetic Stability of the Amorphous Phase of the Chloramphenicol Antibiotic 

    Valenti, Sofia; Romanini, Michela; Franco García, María Lourdes; Puiggalí Bellalta, Jordi; Tamarit Mur, José Luis; Macovez, Roberto (2018-10-23)
    Article
    Accés restringit per política de l'editorial
    We employ broadband dielectric spectroscopy to study the relaxation dynamics and crystallization kinetics of a broad-spectrum antibiotic, chloramphenicol, in its supercooled liquid form. Two dynamic processes are observed: ...

  • Immunization strategies for epidemic processes in time-varying contact networks 

    Starnini, Michele; Machens, Anna; Cattuto, Ciro; Barrat, Alain; Pastor Satorras, Romualdo (2013)
    Article
    Accés obert
    preading processes represent a very efficient tool to investigate the structural properties of networks and the relative importance of their constituents, and have been widely used to this aim in static networks. Here we ...

  • Mean-field analysis of the q-voter model on networks 

    Moretti, Paolo; Liu, Suyu; Castellano, Claudio; Pastor Satorras, Romualdo (2013-04-01)
    Article
    Accés obert
    We present a detailed investigation of the behavior of the nonlinear q-voter model for opinion dynamics. At the mean-field level we derive analytically, for any value of the number q of agents involved in the elementary ...

  • Full-Scale Wind Turbine Vibration Signature Analysis 

    Escaler Puigoriol, Francesc Xavier; Mebarki, Toufik (2018-12-07)
    Article
    Accés obert
    A sample of healthy wind turbines from the same wind farm with identical sizes and designs was investigated to determine the average vibrational signatures of the drive train components during normal operation. The units ...

  • Tuning the thermal properties and morphology of isodimorphic poly[(butylene succinate)-ran-(e-caprolactone)] copolyesters by changing composition, molecular weight, and thermal history 

    Safari, Maryam; Martínez de Ilarduya Sáez de Asteasu, Domingo Antxon; Múgica, Agurtzane; Zubitur, Manuela; Muñoz Guerra, Sebastián; Müller, Alejandro Jesús (American Chemical Society (ACS), 2018-12-11)
    Article
    Accés restringit per política de l'editorial
    High molecular weight poly[(butylene succinate)- ran-(e-caprolactone)] copolyesters (PBS-ran-PCL) were synthesized in a wide composition range and compared with significantly lower molecular weight samples synthesized ...

  • Project management : gestión integrada de proyectos 

    Serer Figueroa, Marcos Antonio (Iniciativa Digital Politècnica. Oficina de Publicacions Acadèmiques Digitals de la UPC, 2018-11)
    Llibre
    Accés restringit a la comunitat UPC
    La presente obra constata que la disciplina de project management no se mantiene estática en el tiempo, sino que se va adaptando y mejorando con la implicación de nuevas tecnologías y nuevos procedimientos cada vez más ...

  • Numerical study on the influence of acoustic natural frequencies on the dynamic behaviour of submerged and confined disk-like structures 

    Bossio, Matias; Valentín Ruiz, David; Presas Batlló, Alexandre; Ramos Martín, David; Egusquiza Estévez, Eduard; Valero Ferrando, Ma. del Carmen; Egusquiza Montagut, Mònica (2017-08)
    Article
    Accés restringit per política de l'editorial
    The dynamic response of disks has been deeply studied in the last years given that their dynamic characteristics present similarities with more complex disk-like structures used in real engineering applications, such as ...
