    Acampora, Alessandro (Date of defense: 2013-07-30)

    It is widely believed that many drawbacks in today's wireless communication paradigm might be relieved by enabling high carrier frequency transmission, and endowing both the network and the user equipment with some degree ...

    Nonlinear subgrid finite element models for low Mach number flows coupled with radiative heat transfer 

    Avila, Matías (Date of defense: 2012-11-16)

    The general description of a fluid flow involves the solution of the compressible Navier-Stokes equations, a very complex problem whose mathematical structure is not well understood. It is widely accepted that these equations ...

    Nonlocal Lagrangian Formalism 

    Heredia Pimienta, Carlos (Date of defense: 2023-03-31)

    [eng] This thesis aims to study nonlocal Lagrangians with a finite and an infinite number of degrees of freedom. We obtain an extension of Noether's theorem and Noether's identities for such Lagrangians. We then set up a ...

    Nonlocal resources for quantum information tasks 

    Curchod, Florian John (Date of defense: 2018-10-11)

    This thesis focusses on the essential features of Quantum Theory that are systems in an entangled state and Bell nonlocal correlations. Here, we take the angle of a resource theory and are interested in understanding better ...

    Nonlocality in multipartite correlation networks 

    Würflinger, Lars Erik (Date of defense: 2013-09-18)

    Despite the success of quantum mechanics in predicting the outcomes of experiments in many branches of physics, the foundations of the theory have remained subject of research and dispute. At the basis of this struggle ...

    Nonmesonic weak decay of Hypemuclei, The 

    Parreño Garcia, Assumpta (Date of defense: 1997-05-22)

    In single A hypernuclei, a A hyperon can occupy any orbital in the hypernucleus since it is free from the Pauli exclusion principle due to its additional quantum number strangeness. <br/><br/>Due to the Pauli blocking ...

    Nontypeable Haemophilus influenzae: colonization, infection and biofilm formation 

    Puig Pitarch, Carmen (Date of defense: 2015-06-17)

    Haemophilus influenzae is an opportunistic pathogen that forms part of the human nasopharyngeal microbiota. This microorganism is classified into encapsulated and nonencapsulated or nontypeable (NTHi) isolates, depending ...
