    • A parallel tool for numerical approximation of 3D electromagnetic surveys in geophysics 

      Castillo Reyes, Octavio; de la Puente Álvarez, Josep; Modesto Galende, David; Puzyrev, Vladimir; Cela Espín, José M. (Instituto Politécnico Nacional (México), 2016)
      Article
      Open Access
      This paper presents an edge-based parallel code for the data computation that arises when applying one of the most popular electromagnetic methods in geophysics, namely, the controlled-source electromagnetic method (CSEM). ...
    • Analysis of the key features of the seismic actions due to the three main earthquakes of May 11, 2011 in Lorca, Spain 

      Aguilar Meléndez, Armando; de la Puente Álvarez, Josep; Monterrubio Velasco, Marisol; Rodriguez Lozoya, Héctor Enrique; Rojas, Otilio; Calderón Ramón, Celia M.; Castillo Reyes, Octavio; García Elías, Alejandro; Campos Ríos, Amelia (2019)
      Article
      Open Access
      The seismic records are in general valuable information, especially in cases where damage in buildings has occurred. The main purpose of the present document is to describe the principal results of the analysis of features ...
    • Detection, counting, and classification of visual ganglia columns of drosophila pupae 

      Arriaga Varela, Enrique Javier; Moya Sánchez, Eduardo Ulises; Aguilar Meléndez, Armando; Castillo Reyes, Octavio; Vázquez Santacruz, Eduardo; Salazar Colores, Sebastián; Cortés García, Claudio Ulises (2019)
      Article
      Open Access
      Many neurobiologists use the fruit fly (Drosophila) as a model to study neuron interaction and neuron organization and then extrapolate this knowledge to the nature of human neurological disorders. Recently, the fluorescence ...
    • Edge-elements formulation of 3D CSEM in geophysics : a parallel approach 

      Castillo Reyes, Octavio (Universitat Politècnica de Catalunya, 2017-10-23)
      Doctoral thesis
      Open Access
      Electromagnetic methods (EM) are an invaluable research tool in geophysics whose relevance has increased rapidly in recent years due to its wide industrial adoption. In particular, the forward modelling of three-dimensional ...

    • Land CSEM simulations and experimental test using metallic casing in a geothermal exploration context: Vallès Basin (NE Spain) case study 

      Castillo Reyes, Octavio; Queralt Capdevila, Pilar; Marcuello Pascual, Alex; Ledo Fernandez, Juanjo (Institute of Electrical and Electronics Engineers, 2021)
      Article
      Open Access
      Controlled-source electromagnetic (CSEM) measurements are complementary data for magnetotelluric (MT) characterization although its methodology on land is not sufficiently developed and tested as in marine environments. ...
    • Parallel 3-D marine controlled-source electromagnetic modelling using high-order tetrahedral Nédélec elements 

      Castillo Reyes, Octavio; de la Puente Álvarez, Josep; García-Castillo, Luis Emilio; Cela Espín, José M. (Oxford University Press, 2019-10)
      Article
      Open Access
      We present a parallel and high-order Nédélec finite element solution for the marine controlled-source electromagnetic (CSEM) forward problem in 3-D media with isotropic conductivity. Our parallel Python code is implemented ...
    • PETGEM: A parallel code for 3D CSEM forward modeling using edge finite elements 

      Castillo Reyes, Octavio; de la Puente Álvarez, Josep; Cela Espín, José M. (2018-10)
      Article
      Open Access
      We present the capabilities and results of the Parallel Edge-based Tool for Geophysical Electromagnetic modeling (PETGEM), as well as the physical and numerical foundations upon which it has been developed. PETGEM is an ...
    • Towards an open-source landscape for 3-D CSEM modelling 

      Werthmüller, Dieter; Rochlitz, Raphael; Castillo Reyes, Octavio; Heagy, Lindsey (2021-10)
      Article
      Open Access
      Large-scale modelling of 3-D controlled-source electromagnetic (CSEM) surveys used to be feasible only for large companies and research consortia. This has changed over the last few years, and today there exists a selection ...
