      Obesity is a public health problem worldwide, and especially in women in reproductive age where more than one in three have obesity. Maternal obesity is associated with an increased maternal, placental, and newborn oxidative ...
    • Ochoa Delorenzi, Sergio; Santos, Rodrigo (Elsevier, 2015)
      When a natural disaster hits an urban area, the first 72 h after are the most critical. After that period the probability of finding survivors falls dramatically, therefore the search and rescue activities in that area must ...

    • Fernández Curotto, Juan Pablo (Universidad de Chile, 2008)
      El presente trabajo de título tiene como finalidad estudiar los problemas que genera la humedad del suelo en viviendas de albañilería y hormigón armado que se construyen en la provincia de Santiago. La humedad proveniente ...
    • Morales Cuevas, Juan Antonio (Universidad de Chile, 2019)
      En este trabajo se analiza la asociación y distribución del As y Fe en la fase sólida de humedales construidos de flujo subsuperficial horizontal a escala de laboratorio, en cuatro ubicaciones dentro de cada uno, variando ...
    • Araneda Gallardo, Ignacio Andrés (Universidad de Chile, 2016)
      En el presente Trabajo de Título se construyeron cuatro columnas de humedales construidos a escala de laboratorio, las que se operaron con agua gris sintética y finalmente se realizaron análisis de las muestras de afluentes ...
    • Vargas Pérez, Melissa Paz (Universidad de Chile, 2018)
      El arsénico (As) es un metaloide altamente tóxico y que en ambientes naturales suele encontrarse junto con el hierro (Fe), un metal esencial para la salud humana y que no genera efectos nocivos en concentraciones menores ...
    • Orellana Gutiérrez, Diego Ariel Andrés (Universidad de Chile, 2019)
      En la ingeniería de software resulta clave entender la estructura del código de un proyecto para poder implementar de forma efectiva las funcionalidades requeridas por el cliente. Sin embargo, es común en la industria que ...
    • Carro, Lorena; Razmilic, Valeria; Nouioui, Imen; Richardson, Lee; Pan, Che; Golinska, Patrycja; Asenjo, Juan; Bull, Alan; Klenk, Hans; Goodfellow, Michael (Springer Netherlands, 2018)
      Innovative procedures were used to selectively isolate small numbers of Micromonospora strains from extreme hyper-arid and high altitude Atacama Desert soils. Micromonosporae were recognised on isolation plates by their ...
    • Cortés, Cristián E.; Núñez, Alfredo; Sáez Hueichapán, Doris (JOHN WILEY & SONS, 2008-03)
      This paper presents a hybrid adaptive predictive control approach to incorporate future information regarding unknown demand and expected traffic conditions, in the context of a dynamic pickup and delivery problem with ...
    • Arroyuelo, Diego; Oyarzún, Mauricio; González, Senén; Sepúlveda, Víctor (Elsevier Ltd, 2018)
      Text search engines are a fundamental tool nowadays. Their efficiency relies on a popular and simple data structure: inverted indexes. They store an inverted list per term of the vocabulary. The inverted list of a given ...
    • Causa, Javier; Karer, Gorazd; Núñez, Alfredo; Sáez Hueichapán, Doris; Škerjanc, Igor; Zupančič, Borut (PERGAMON-ELSEVIER SCIENCE LTD, 2008-12-22)
      In this paper we describe the design of hybrid fuzzy predictive control based on a genetic algorithm (GA). We also present a simulation test of the proposed algorithm and a comparison with two hybrid predictive control ...
    • Trye, D; Calude, AS; Bravo-Marquez, F; Keegan, TT (Frontiers Media S.A., 2020)
    • Donoso Merlet, Felipe Octavio (Universidad de Chile, 2021)
      Esta tesis presenta 2 estrategias de control para asegurar el balance de las celdas de un conversor modular multinivel hibrido, que opera en sobremodulación. Se desarrolla y presenta un control desacoplado para regular ...
    • Sáez Hueichapán, Doris; Cortés, Cristián E.; Milla Nanjarí, Freddy; Núñez, Alfredo; Tirachini Hernández, Alejandro; Riquelme, Marcela (Taylor & Francis, 2012)
      In this article, a hybrid predictive control (HPC) strategy is formulated for the real-time optimisation of a public transport system operation run using buses. For this problem, the hybrid predictive controller corresponds ...
    • Motelet, Olivier; Baloian Tataryan, Nelson; Pino Urtubia, José (2007-05-03)
      Generating LOM for learning material is a complex and tedious task to be manually completed. Therefore, the current trend is to automate this process. However, there are several important issues restricting this approach. ...
    • Blanchet, Adrien; Carrillo, José Antonio; Kinderlehrer, David; Kowalczyk, Michal; Laurençot, Philippe; Lisini, Stefano (EDP Sciences, 2015)
      We construct weak global in time solutions to the classical Keller-Segel system describing cell movement by chemotaxis in two dimensions when the total mass is below the established critical value. Our construction takes ...
    • Núñez, Alfredo; De Schutter, Bart; Sáez Hueichapán, Doris; Škrjanc, Igor (Elsevier, 2014)
      In this paper a class of hybrid-fuzzy models is presented, where binary membership functions are used tocapture the hybrid behavior. We describe a hybrid-fuzzy identification methodology for non-linear hybridsystems with ...
