    • Acoustic emission analysis for the detection of appropriate cutting operations in honing processes 

      Buj Corral, Irene; Álvarez Flórez, Jesús Andrés; Domínguez Fernandez, Alejandro (2018-01-15)
      Article
      Open Access
      In the present paper, acoustic emission was studied in honing experiments obtained with different abrasive densities, 15, 30, 45 and 60. In addition, 2D and 3D roughness, material removal rate and tool wear were determined. ...

    • Built in dampers for stayed cables in bridges via SMA. The SMARTeR-ESF project: a mesoscopic and macroscopic experimental analysis with numerical simulations 

      Torra Ferré, Vicenç; Auguet Sangrá, Carlota E.; Isalgué Buxeda, Antonio; Carreras, Guillem; Terriault, Patrick; Lovey, Francisco Carlos (Elsevier, 2013-04)
      Article
      Open Access
      Shape Memory Alloys (SMAs) are good candidates for solid-state dampers appropriate for the oscillations of bridge stay cables because of their large recoverable strain, hysteresis and reasonable fatigue-life. This work ...
    • Cleaning and measuring tools using digital image processing methods 

      Torres Xirau, Iban (Universitat Politècnica de Catalunya / Fraunhofer-Institut für Produktionsanlagen und Konstruktionstechnik, 2013-07-31)
      Master thesis (pre-Bologna period)
      Open Access
      Covenantee:   Technische Universität Berlin
      [ANGLÈS] Many industrial machines use screws and other small tools to fix smaller components that compose the whole structure of the machine. To ensure that these tools withstand the pressures that can be subjected at, a ...
    • Deterministic analysis of the accuracy in FFT hardware architectures 

      Guinart Platero, David (Universitat Politècnica de Catalunya / Linköpings Universitet, 2012-06-07)
      Master thesis (pre-Bologna period)
      Open Access
      [ANGLÈS] This Master Thesis studies the different quantization effects in hardware architecture due to the use of finite word lenght. This master thesis gives a deterministic analysis with relation to the accuracy and ...
    • Deterministic thermal lanscape engineering at the microscale level by optical beam shaping with phase-only hologram 

      Lebon, Alexander (Universitat Politècnica de Catalunya, 2018-09-06)
      Master thesis
      Restricted access - author's decision
      An optical beam shaping system based on a phase-only spatial light modulator (SLM) was integrated into a holographic optical microscope developed to deliver heat locally and measure the resulting temperature in a label-free ...
    • Estudio de la previsión de las series de tráfico por medio de la transformada Wavelet 

      Gelabert Serra, Juan (Universitat Politècnica de Catalunya, 2016-10)
      Master thesis (pre-Bologna period)
      Open Access
      Nowadays, the amount of information that communications networks support due to its rise, makes necessary the distribution of different information flows, to avoid saturation and information lose. This project aims to ...
    • Generalized formulation of an encryption system based on a joint transform correlator and fractional Fourier transform 

      Vilardy Ortiz, Juan Manuel; Torres, Yezid; Millán Garcia-Varela, M. Sagrario; Pérez Cabré, Elisabet (Institute of Physics (IOP), 2014-12-01)
      Article
      Open Access
      We propose a generalization of the encryption system based on double random phase encoding (DRPE) and a joint transform correlator (JTC), from the Fourier domain to the fractional Fourier domain (FrFD) by using the fractional ...

    • Log-periodic optical antennas 

      Pavlov, Radostin Stefanov (Universitat Politècnica de Catalunya, 2011-09-07)
      Master thesis
      Open Access
      English: In recent years optical antennas have been attracting very strong interest due to the unique possibilities they offer for manipulating light on a sub-wavelength scale. Most published work deals with relatively ...
    • Non-linear spectral estimation 

      Lagunas Hernandez, Miguel A. (Institute of Electrical and Electronics Engineers (IEEE), 1987)
      Conference report
      Open Access
      This work describes the use of constraints in variational procedures for spectral analysis. It is reported how the designer in a variational approach for spectral estimation has to select a set of constraints. At the same ...
    • Rayleigh estimates: performing like SVD 

      Lagunas Hernandez, Miguel A.; Cabrera-Bean, Margarita (1988)
      Conference report
      Open Access
      This paper describes the structure of the so- called Rayleigh estimates and the features they share with indirect SVD like procedures. The problem of finding procedures of high resolution in spectral estimation is faced ...
