    • A theoretical model of the endothelial cell morphology due to different waveforms 

      Sáez, Pablo; Malvè, Mauro Upna; Martínez, Miguel Ángel (Elsevier, 2015)   Artículo / Artikulua  OpenAccess
      Endothelial cells are key units in the regulatory biological process of blood vessels. They represent an interface to transmit variations on the fluid dynamic changes. They are able to adapt its cytoskeleton, by means of ...
    • Thermoelectric generators for waste heat harvesting: a computational and experimental approach 

      Aranguren Garacochea, Patricia Upna; Araiz Vega, Miguel Upna; Astrain Ulibarrena, David Upna; Martínez Echeverri, Álvaro Upna (Elsevier, 2017)   Artículo / Artikulua  OpenAccess
      Waste heat generation has a widespread presence into daily applications, however, due to the low-temperature grade which presents, its exploitation with the most common technologies is complicated. Thermoelectricity ...
    • Thermoelectric power generation optimization by thermal design means 

      Aranguren Garacochea, Patricia Upna; Astrain Ulibarrena, David Upna (InTechOpen, 2016)   Capítulo de libro / Liburuen kapitulua  OpenAccess
      One of the biggest challenges of the twenty‐first century is to satisfy the demand for electrical energy in an environmentally speaking clean way. Thus, it is very important to search for new alternative energy sources ...
    • Thermoelectric self-cooling for power electronics: increasing the cooling power 

      Martínez Echeverri, Álvaro Upna; Astrain Ulibarrena, David Upna; Aranguren Garacochea, Patricia Upna (Elsevier, 2016)   Artículo / Artikulua  OpenAccess
      Thermoelectric self-cooling was firstly conceived to increase, without electricity consumption, the cooling power of passive cooling systems. This paper studies the combination of heat pipe exchangers and thermoelectric ...
    • Thermoelectric-driven autonomous sensors for a biomass power plant 

      Rodríguez García, Antonio Upna; Astrain Ulibarrena, David Upna; Martínez Echeverri, Álvaro Upna; Gubía Villabona, Eugenio Upna; Sorbet Presentación, Francisco Javier Upna (Springer USTMSIEEE, 2013)   Artículo / Artikulua  OpenAccess
      This work presents the design and development of a thermoelectric generator intended to harness waste heat in a biomass power plant, and generate electric power to operate sensors and the required electronics for wireless ...
    • Zero-power-consumption thermoelectric system to prevent overheating in solar collectors 

      Martínez Echeverri, Álvaro Upna; Astrain Ulibarrena, David Upna; Rodríguez García, Antonio Upna (Elsevier, 2014)   Artículo / Artikulua  OpenAccess
      Highly promoted by the European Union Climate and Energy Package for 2020, solar collectors stand out as the most promising alternative to meet water heating demands. One of the most limiting problems in these systems ...
