    • A Hybrid VLC-RF Portable Phasor Measurement Unit for Deep Tunnels 
      Soto, Ismael; Nilson Rodrigues, Rafael; Massuyama, Gabriel; Seguel, Fabián; Palacios Játiva, Pablo; Azurdia Meza, César; Krommenacker, Nicolás (MDPI, 2020)
      In this manuscript we propose a hybrid Visible Light Communication and Radio Frequency (VLC-RF) scheme for the implementation of a portable Phaser Measurement Unit (PMU) for deep underground tunnels. Through computer ...
    • A VLC Channel Model for Underground Mining Environments With Scattering and Shadowing 
      Palacios Jativa, Pablo; Azurdia Meza, César; Sánchez, Iván; Seguel, Fabián; Zabala Blanco, David; Firoozabadi, Ali Dehghan; Gutiérrez, Carlos A.; Soto, Ismael (IEEE-Inst Electrical Electronics Engineers, 2020)
      Underground mining is an industry that preserves the miners' safety and efficiency in their work using wireless communication systems as a tool. In addition to communication links characterized by radio frequency signals, ...
    • Interference mitigation for visible light communications in underground mines using angle diversity receivers 
      Palacios Játiva, Pablo Geovanny; Román Canizares, Milton; Azurdia Meza, César; Zabala Blanco, David; Dehghan Firoozabad, Ali; Seguel, Fabián; Montejo Sánchez, Samuel; Soto, Ismael (MDPI, 2020)
      This paper proposes two solutions based on angle diversity receivers (ADRs) to mitigate inter-cell interference (ICI) in underground mining visible light communication (VLC) systems, one of them is a novel approach. A ...
    • Predicting bubble size and bubble rate data in water and in froth flotation-like slurry from computational ... 
      Montes Atenas, Gonzalo; Seguel, Fabián; Valencia Musalem, Álvaro; Masood Bhatti, Sohail; Salman Khan, Muhammad; Soto Gómez, Ismael; Becerra Yoma, Néstor (Pergamon-Elsevier, 2016)
      Accurate characterization of two phase bubbly flows is crucial in many industrial processes such as fluidized reactors, ore froth flotation, etc. The bubble size determines the rate at which components present in the gas ...
