      Article
      Accés obert
      To estimate the probability distributions of power fades, we consider two basic types of disturbance in electromagnetic wave propagation through atmospheric turbulence: wave-front intensity fluctuations and wave-front ...

      Treball Final de Grau
      Accés obert
      This work has the objective to simulate the variation of the compressive resistance strength of concrete along the height of a structural member. The concrete compressive strength is calculated with a formula, which has ...
    • Exploiting polarimetric TerraSAR-X data for sea clutter characterization 

      Makhoul Varona, Eduardo; López Martínez, Carlos; Broquetas Ibars, Antoni (Institute of Electrical and Electronics Engineers (IEEE), 2016-01-01)
      Article
      Accés obert
      This paper presents a detailed characterization of sea/ocean clutter returns at X-band, imaged by TerraSAR-X (TSX) mission from the radiometric, statistical, and polarimetric standpoints. Different TSX data takes, covering ...
    • Global sizing optimisation using dual-level response surface method based on mixed-resolution central composite design for permanent magnet synchronous generators 

      Asef, Pedram; Bargalló Perpiñá, Ramón; Barzegaran, M.R. (2018-05-01)
      Article
      Accés obert
      This study presents a global sizing design optimisation of a permanent magnet synchronous generator (PMSG) using the three-dimensional finite-element analysis (3D FEA). To build an optimal parametric model structure, the ...
    • Micromechanics in additively manufactured metals using electron beam-based powder bed fusion 

      Barberá Flichi, Francesc (Universitat Politècnica de Catalunya, 2023-06-28)
      Treball Final de Grau
      Accés obert
      Els metalls obtinguts mitjançant fusió de llits de pols (PBF, Powder Bed Fusion), concretament per la tècnica de fusió per feix d'electrons (EB, Electron Beam), poden tenir propietats diferents, ja siguin físiques o ...
    • Peptide delta-turn: Literature survey and recent progress 

      Toniolo, Claudio; Crisma, Marco; Moretto, Alessandro; Peggion, Cristina; Formaggio, Fernando; Alemán Llansó, Carlos; Cativiela, Carlos; Ramakrishnan, Chandrasekharan; Balaram, Padmanabhan (2015-09-28)
      Article
      Accés obert
      Among the various types of a-peptide folding motifs, delta-turn, which requires a central cis-amide disposition, has been one of the least extensively investigated. In particular, this main-chain reversal topology has been ...
    • Statistical properties of silence gap in public mobile telephony channels with application to data transmission 

      Barceló Arroyo, Francisco (IEEE, 2001-06)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      This paper examines the probability distribution of the channel idle time in mobile public telephony systems: personal communication systems (PCS) and private mobile radio (PMR). Results are used to predict the time available ...
    • Statistical study of personal computer cluster harmonic currents from experimental measurements
