Ítem Diseño de un sistema de adsorción para la separación de CO2(Universidad EAFIT, 2022) Reinoso Rojas, Aminta Elena; Bermúdez Ríos, Carlos Arturo; Builes Toro, SantiagoÍtem Evaluación de un sistema de fotobiorreactores urbano para la captación de material particulado y CO2 mediante microalgas(Universidad EAFIT, 2022) Quintero Montoya, Sara; Jiménez Suárez, Ana Rosa; Sáez Vega, Alex Armando; Miranda Parra, Alejandra MaríaPublicación La configuración y reconfiguración de las fronteras entre entidades de conocimiento colectivo(Universidad EAFIT, 2024) Diez-Gaviria, Ana Cecilia; Vélez-Castiblando, JorgeÍtem New insights into Late Devonian vertebrates and associated fauna from the Cuche Formation (Floresta Massif, Colombia)(Taylor & Francis, 2019-01-01) Olive, Sebastien; Pradel, Alan; Martinez-Perez, Carlos; Janvier, Philippe; Lamsdell, James C.; Gueriau, Pierre; Rabet, Nicolas; Duranleau-Gagnon, Philippe; Cardenas-Rozo, Andres L.; Zapata Ramirez, Paula A.; Botella, Hector; Universidad EAFIT. Departamento de Ciencias; Biodiversidad, Evolución y ConservaciónNew vertebrate remains are reported from the Late Devonian (?Frasnian) Cuche Formation of northeastern Colombia, including a new taxon of antiarch placoderm (Colombialepis villarroeli, gen. et sp. nov., previously reported as Asterolepis) and a new taxon of arthrodiran placoderm (Colombiaspis rinconensis, gen. et sp. nov.). We also report evidence of a stegotrachelid actinopterygian, a diplacanthid acanthodian (cf. Florestacanthus morenoi), a second antiarch placoderm (Bothriolepis sp.), a putative megalichthyid, and a putative tristichopterid. The absence of typical Euramerican markers, e.g., Asterolepis and Strepsodus, in this assemblage suggests that faunal interchange between Euramerica and Gondwana was less pronounced during the Frasnian-Famennian than previously thought (i.e., the Great Devonian Interchange hypothesis). Three arthropod taxa, including two families of spinicaudatan branchiopods and the eurypterid Pterygotus cf. bolivianus, are found to be associated with the reported vertebrate fauna. Pterygotus cf. bolivianus represents the first eurypterid described from Colombia and the youngest known pterygotid eurypterid, highlighting that pterygotids, which were competitors for large predatory fishes, did not go extinct during the major vertebrate radiation in the Early and Middle Devonian.Ítem New insights into Late Devonian vertebrates and associated fauna from the Cuche Formation (Floresta Massif, Colombia)(Taylor & Francis, 2019-01-01) Olive, Sebastien; Pradel, Alan; Martinez-Perez, Carlos; Janvier, Philippe; Lamsdell, James C.; Gueriau, Pierre; Rabet, Nicolas; Duranleau-Gagnon, Philippe; Cardenas-Rozo, Andres L.; Zapata Ramirez, Paula A.; Botella, Hector; Universidad EAFIT.

Departamento de Ingeniería de Sistemas; I+D+I en Tecnologías de la Información y las ComunicacionesGraphical Processing Units (GPUs) have become more accessible peripheral devices with great computing capacity. Moreover, GPUs can be used not only to accelerate the graphics produced by a computer but also for general purpose computing. Many researchers use this technique on their personal workstations to accelerate the execution of their programs and have often encountered that the amount of memory available on GPU cards is typically smaller than the amount of memory available on the host computer. We are interested in exploring approaches to solve problems with this restriction. Our main contribution is to devise ways in which portions of the problem can be moved to the memory of the GPU to be solved using its multiprocessing capabilities. We implemented on a GPU the Jacobi iterative method to solve systems of linear equations and report the details from the results obtained, analyzing its performance and accuracy. Our code solves a system of linear equations large enough to exceed the card’s memory, but not the host memory. Significant speedups were observed, as the execution time taken to solve each system is faster than those obtained with Intel® MKL and Eigen, libraries designed to work on CPUs. © Springer Nature Switzerland AG 2018.Ítem Universidad, empresa y Estado : aliados en sintonía con la sociedad(Medellín : Universidad EAFIT, 2022-12-02) Restrepo Montoya, Claudia Patricia; Hoyos Lopera, Alberto; Universidad EAFIT; Compañía de Galletas Noel
