    • Análisis de la evolución de las propiedades: ductilidad, tenacidad y flexibilidad de los betunes durante su envejecimiento 

      García Gil, Lívia; Pérez Jiménez, Félix Edmundo; Miró Recasens, José Rodrigo (2018)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      En el estudio del envejecimiento de los betunes a penas se ha tenido en cuenta su propiedad más característica: su poder aglomerante. Los ligantes bituminosos aglomeran los áridos mediante unas uniones dúctiles y tenaces. ...

    • Effect of Filler on the Aging Potential of Asphalt Mixtures 

      Miró Recasens, José Rodrigo; Martínez Reguero, Adriana Haydée; Pérez Jiménez, Félix Edmundo; Bianchetto, Hugo Daniel (Transportation Research Board of the National Academies, 2005-09)
      Article
      Accés obert
      In this work, the effect that filler has on the aging of bitumen was analyzed but with the filler being incorporated by volume, not by weight. The Universal de Caracterización de Ligantes method was used as the process of ...

    • Effects of strain aging in NiTi SMA wires for dampers 

      Auguet Sangrá, Carlota E.; Isalgué Buxeda, Antonio; Torra, Vicenç; Carreras, Guillem; Lovey, Francisco Carlos (Universidad del Pais Vasco, 2014)
      Text en actes de congrés
      Accés obert
      SMA NiTi wires experience evolution under constrained aging. A strain and temperature aging sequence is designed and experimented, to ascertain the functionality of the dampers exposed to weathering

    • Experimental monitoring of the gain in RF Power Amplifiers using Temperature Measurements 

      Gisbert Beguer, Xavier (Universitat Politècnica de Catalunya, 2022-05-24)
      Projecte Final de Màster Oficial
      Accés obert
      The Aging effect is intrinsic to transistors in integrated circuits and occurs sooner with newer, smaller manufacturing node technologies. With prolonged usage within the nominal power and biasing operating point, some ...

    • Impedance characterization of an LCO-NMC/graphite cell: ohmic conduction, SEI transport and charge-transfer phenomenon 

      Ovejas Benedicto, Victòria Júlia; Cuadras Tomàs, Àngel (Multidisciplinary Digital Publishing Institute (MDPI), 2018-09-10)
      Article
      Accés obert
      Currently, Li-ion cells are the preferred candidates as energy sources for existing portable applications and for those being developed. Thus, a proper characterization of Li-ion cells is required to optimize their use and ...

    • Irreversible entropy model for damage diagnosis in resistors 

      Cuadras Tomàs, Àngel; Crisóstomo, Javier; Ovejas Benedicto, Victòria Júlia; Quílez Figuerola, Marcos (American Institute of Physics (AIP), 2015-10-28)
      Article
      Accés obert
      We propose a method to characterize electrical resistor damage based on entropy measurements. Irreversible entropy and the rate at which it is generated are more convenient parameters than resistance for describing damage ...

    • Material aging for game environments 

      Antón Domínguez, Victor (Universitat Politècnica de Catalunya, 2019-06)
      Projecte Final de Màster Oficial
      Accés obert
      We propose a software and work-flow to create 3D model imperfections and aging effects while adding very little overhead to the rendering time of the models. Specifically, we implement a tool that adds all these effects ...

    • Mechanical relaxation of metallic glasses: an overview of experimental data and theoretical models 

      Liu, Chaoren; Pineda Soler, Eloi; Crespo Artiaga, Daniel (2015-06)
      Article
      Accés obert
      Relaxation phenomena in glasses are a subject of utmost interest, as they are deeply connected with their structure and dynamics. From a theoretical point of view, mechanical relaxation allows one to get insight into the ...

    • Obtaining the fatigue laws of bituminous mixtures from a strain sweep test: effect of temperature and aging 

      López Montero, Teresa; Miró Recasens, José Rodrigo; Botella Nieto, Ramón; Pérez Jiménez, Félix Edmundo (2017-07)
      Article
      Accés obert
      Fatigue is associated with the deterioration caused by applying repeated loads, and is affected by temperature or aging. Generally, time sweep tests are used to simulate fatigue, in order to obtain the fatigue laws. However, ...

    • Principal component analysis of the effects of environmental enrichment and (-)-epigallocatechin-3-gallate on age-associated learning deficits in a mouse model of Down Syndrome 

      Catuara, Silvina; Espinosa Carrasco, Jose; Erb, Ionas; Langohr, Klaus; Notredame, Cedric; Gonzalez, Juan R.; Dierssen, Mara (2015-12-11)
      Article
      Accés obert
      Down syndrome (DS) individuals present increased risk for Alzheimer's disease (AD) neuropathology and AD-type dementia. Here, we investigated the use of green tea extracts containing (-)-epigallocatechin-3-gallate (EGCG), ...

    • Size and aging effects on antimicrobial efficiency of silver nanoparticles coated on polyamide fabrics activated by atmospheric DBD plasma 

      Zille, Andrea; Macedo Fernandes, Margarida Maria; Francesko, Antonio; Tzanov, Tzanko; Fernandes Sousa, Marta; Oliveira, Fernando R.; Almeida Torres, Luís; Amorim Lago, Teresa; Carneiro, Noémia; Esteves, Maria Fernanda; Souto, António Pedro (2015-06-09)
      Article
      Accés obert
      This work studies the surface characteristics, antimicrobial activity, and aging effect of plasma-pretreated polyamide 6,6 (PA66) fabrics coated with silver nanoparticles (AgNPs), aiming to identify the optimum size of ...
