    Planas Lisbona, Mireia; Sallés Rius, Anna; Sebastián Esandi, Naila (Universitat Politècnica de Catalunya, 2021-06-04)
    Coursework
    Open Access
    The aim of this project is to design an asymmetric encoder and develop an algorithm able to estimate the angular speed and direction of rotation using a single set of slits and detectors. This proposed algorithm will be ...

  • Frequency chirp reduction in Mach-Zehnder modulators 

    Calero, Héctor; Guerrero, Quim (Universitat Politècnica de Catalunya, 2021-06-04)
    Coursework
    Open Access
    We present our study of the Mach-Zehnder modulator (MZM) and the transmission of pure tone radiofrequency signals through an optical ber link. Our results show that the detected signal at the receiver vanishes at a speci ...

  • Terminal Control Of A 2-Link Robot Manipulator 

    De Castro, Josep Maria; Domínguez Pla, Paula; Palau, Nil (Universitat Politècnica de Catalunya, 2021-06-04)
    Coursework
    Open Access
    This paper describes a comparative evaluation of different controllers for a position regulation 2-link robot manipulator. The equation of motion for two link robot is a nonlinear di erential equation. The controllers, namely ...

  • Boundary conditions and Rankine-Hugoniot condition in computational acoustics 

    Florit, Enric; Gómez, Roger (Universitat Politècnica de Catalunya, 2021-06-04)
    Coursework
    Open Access
    In this work we derive a procedure that permits the implementation of suitable boundary condi- tions in the nite volume method for problems in acoustics. Afterwards, we validate the procedure through numerical experiments ...
