    • A Parallel Framework with Block Matrices of a Discrete Fourier Transform for Vector-Valued Discrete-Time Signals 

      Soto-Quiros, Pablo (Hindawi Publishing Corporation, 2015)
      This paper presents a parallel implementation of a kind of discrete Fourier transform (DFT): the vector-valued DFT. The vector-valued DFT is a novel tool to analyze the spectra of vector-valued discrete-time signals. This ...
    • A port-Hamiltonian system modelling approach and passivity-based nonlinear control design for photovoltaic energy harvesting 

      Phillips-Brenes, Hayden Anthony (Instituto Tecnológico de Costa Rica, 2023)
      En este trabajo se dise˜nan y evaluan nuevas leyes de control no lineal para el rastreo del punto de m´axima potencia y la regulaci´on de voltaje, mediante el control de los estados de conmutaci´on de una etapa de ...

    • A simple approach for the design of operational transconductance amplifiers for low power signal processing 

      Chacón-Rodríguez, Alfonso; Sondon, Santiago; Mandolesi, Pablo; Julián, Pedro (IEEE, 2010)
      A simple approach for the design, fabrication and characterization of a operational trasconductance amplifier intended for work in low power applications is reported in this work. DC Measured parameters agree with ...
    • A Texture and Curvature Bimodal Leaf Recognition Model for Costa Rican Plant Species Identification 

      Carranza, Jose (Instituto Tecnológico de Costa Rica, 2014)
      In the last decade, research in Computer Vision has developed algorithms to help botanists and non-experts classify plants based on images of their leaves. Nevertheless, very few efficient tools have resulted from that ...
    • A top-down design approach for an automated testing framework 

      Méndez-Porras, Abel; Nieto-Hidalgo, Mario; García-Chamizo, Juan-Manuel; Jenkins, Marcelo; Martínez-Porras, Alexander (Springer Verlag, 2015)
      Mobile applications have become popular work tools. Portability and ease of Internet connectivity are characteristics that favor this adoption. However, mobile applications sometimes incorrectly process events associated ...
