Diversitat vegetal i factors que influeixen en solars no urbanitzats a Barcelona
(Universitat Politècnica de Catalunya, 2019-10-29)
Treball Final de Grau
Accés obertBarcelona city is dense with a shortage of green spaces and little presence of green in the built space in its urban environment. It has almost 7 m² of green urban area per capita, regardless of Collserola. Therefore, ... -
Diversity and bias through receptor–receptor interactions in GPCR heteroreceptor complexes. Focus on examples from dopamine D2 receptor heteromerization
(2014-05-13)
Article
Accés obertAllosteric receptor–receptor interactions in GPCR heteromers appeared to introduce an intermolecular allosteric mechanism contributing to the diversity and bias in the protomers. Examples of dopamine D2R heteromerization ... -
Diversity and genetic architecture of agro-morphological traits in a core collection of European traditional tomato
(2023-08-01)
Article
Accés obertEuropean traditional tomato varieties have been selected by farmers given their consistent performance and adaptation to local growing conditions. Here we developed a multipurpose core collection, comprising 226 accessions ... -
Diversity and hierarchy in supramolecular assemblies of triphenylalanine: from laminated helical ribbons to toroids
(2017-04-04)
Article
Accés obertMicrostructures from small phenylalanine-based peptides have attracted great attention lately because these compounds are considered to be a new class of tunable materials. In spite of the extensive studies on uncapped ... -
Diversity in mobile communications for blind detection of block-coded modulations
(Institute of Electrical and Electronics Engineers (IEEE), 1999)
Text en actes de congrés
Accés obertSpatial, temporal, and frequency diversity structures are analyzed to address the blind equalization problem in the presence of time-variant frequency selective channels. The aim of the paper is to present equalization ... -
Diversity mdir receiver for space-time dispersive channels
(European Commission, 2000)
Text en actes de congrés
Accés obertA particular property of the cellebrated MDIR receiver is introduced in this communication, namely, the fact that full exploitation of the diversity is obtained with multiple beamformers when the channel is spatially and ... -
Diversity ranking for video retrieval from a broadcaster archive
(2011)
Comunicació de congrés
Accés obertVideo retrieval through text queries is a very common practice in broadcaster archives. The query keywords are compared to the metadata labels that documentalists have previously associated to the video assets. This ... -
Diversity techniques for blind channel equalization in mobile communications
(Institute of Electrical and Electronics Engineers (IEEE), 1997)
Text en actes de congrés
Accés obertA blind algorithm for channel distortion compensation is presented which can be employed in spatial or temporal diversity receivers. The proposed technique can be used in frequency selective and frequency flat fading mobile ... -
Diversity techniques for blind equalization in mobile communications
(1997)
Text en actes de congrés
Accés obertThis paper deals with blind equalization of mobile channels, which are either frequency-selective or multiplicative. The proposed algorithm can be used for channel distortion compensation in diversity systems subject ... -
Diversity, ecology and evolution of marine diazotrophic microorganisms
(Universitat Politècnica de Catalunya, 2017-12-19)
Tesi
Accés obertBiological N2 fixation, the reduction of dinitrogen (N2) gas to biologically available nitrogen, is a fundamental process since it represents a source of new nitrogen for marine life in areas where this important element ... -
Diversity, flexibility and identity: mechanisms for recycling mature tourist destinations
(International Forum on Urbanism / Escola Técnica Superior d'Arquitectura de Barcelona, 2012-01)
Text en actes de congrés
Accés obertGlobalizing dynamic sources are making of tourist destinations, spaces each time more homogeneous, unable to respond to the tourist’s new motivation and to the specific characteristics of the territory and the local ... -
