All-optical soliton control in photonic lattices
(Universitat Politècnica de Catalunya, 2007-11-27)
Tesi
Accés obertLos solitones ópticos son paquetes de luz (haces y/o pulsos) que no se dispersan gracias al balance entre difracción/dispersión y no linealidad. Al propagarse e interactuar los unos con los otros muestran propiedades que ... -
All-regions tunable high harmonic enhancement by a periodic static electric field
(American Institute of Physics (AIP), 2010-02-19)
Article

All-silicon spherical-Mie-resonator photodiode with spectral response in the infrared region
(2014-03-10)
Article
Accés obertSilicon is the material of choice for visible light photodetection and solar cell fabrication. However, due to the intrinsic band gap properties of silicon, most infrared photons are energetically useless. Here, we show ... -

Article
Accés obert© 2017, The Author(s). Advanced LIGO detected a significant gravitational wave signal (GW170104) originating from the coalescence of two black holes during the second observation run on January 4th, 2017. An all-sky ... -
All-solid-state VUV frequency comb at 160 nm using high-harmonic generation in nonlinear femtosecond enhancement cavity
(2019-02-21)
Article
Accés obertWe realized a solid-state-based vacuum ultraviolet frequency comb by harmonics generation in an external enhancement cavity. Optical conversions were so far reported by only using gaseous media. We present a theory that ... -
All-terminal reliability evaluation through a Monte Carlo simulation based on an MPI implementation
(2012)
Text en actes de congrés
Accés obertAll-terminal reliability (ATR), defined as the probability that every node in a network can communicate with every other node, is an important problem in research areas such as mobile ad-hoc wireless networks, grid computing ... -

(Universitat Politècnica de Catalunya, 2023-01-26)
Treball Final de Grau
Accés obertMés ràpid del que ens agradaria, la trajectòria i comportament de la naturalesa està canviant. Sovint, cada cop són més evidents els accidents que involucren fenòmens climàtics. És imprescindible fer l’esforç d’entendre ... -
Allele-Sharing analysis and relationship inference
(Universitat Politècnica de Catalunya / Universitat de Barcelona / Universitat de Girona, 2014-06)
Projecte Final de Màster Oficial
Accés restringit per decisió de l'autorThis master's thesis presents some techniques in statistical genetics to study family relationships. Two individuals can share 0, 1 or 2 alleles for any genetic marker. The larger the number of shared alleles between a ... -
Allelochemicals and esters from leaves and inflorescences of Sambucus nigra L
(2019-04-01)
Article
Accés obertAllelochemical compounds were detected in leaves and inflorescences of Sambucus nigra L. by means of GC-EIMS. The identified compounds were characterized by their mass spectra and relative retention times as their ... -
Allen Bradley PLC programming in the ALBA Synchrotron consortium
(Universitat Politècnica de Catalunya, 2017-06)
Treball Final de Grau
Accés restringit per decisió de l'autorThe world of accelerators is constantly growing and more discoveries are produced by the several experiments performed there. One of the main points of the accelerators is the radio frequency, which is used to accelerate ... -
