  • Weak components of the directed configuration model 

    Coulson, Matthew John; Perarnau Llobet, Guillem (Springer, 2021)
    Conference report
    Restricted access - publisher's policy
    We study the threshold for the existence of a linear order weakly connected component in the directed configuration model, confirming analytic but non-rigorous results recently obtained by Kryven [8]. We also establish ...
  • Shorter lattice-based zero-knowledge proofs for the correctness of a shuffle 

    Herranz Sotoca, Javier; Martínez Pinilla, Ramiro; Sánchez Torrón, Manuel (Springer, 2021)
    Conference report

    In an electronic voting procedure, mixing networks are used to ensure anonymity of the casted votes. Each node of the network re-encrypts the input list of ciphertexts and randomly permutes it in a process named shuffle, ...
  • Subdivided linear and curved meshes preserving features of a linear mesh model 

    Jiménez Ramos, Albert; Gargallo Peiró, Abel; Roca Navarro, Francisco Javier (Sandia National Laboratories, 2019)
    Conference report
    Open Access
    To provide straight-edged and curved piece-wise polynomial meshes that target a unique smooth geometry while preserving the sharp features and smooth regions of the model, we propose a new fast curving method based on ...
  • Regularisation in ejection-collision orbits of the RTBP 

    Ollé Torner, Mercè; Rodríguez del Río, Óscar; Soler Villanueva, Jaume (2018)
    Conference report
    Open Access
    Numerical explorations confirm well-known analytical results on the ex-istence of ejection-collision orbits in the restricted three-body problem for veryrestrictive values of the Jacobi constantC. For different values ...
  • Local bisection for conformal refinement of unstructured 4D simplicial meshes 

    Belda Ferrín, Guillem; Gargallo Peiró, Abel; Roca Navarro, Francisco Javier (Springer, 2018)
    Conference report
    Open Access
    We present a conformal bisection procedure for local refinement of 4D unstructured simplicial meshes with bounded minimum shape quality. Specifically, we propose a recursive refine to conformity procedure in two stages, ...
  • Defining a stretching and alignment aware quality measure for linear and curved 2D meshes 

    Aparicio Estrems, Guillermo; Gargallo Peiró, Abel; Roca Navarro, Francisco Javier (Springer, 2018)
    Conference report
    Open Access
    We define a regularized shape distortion (quality) measure for curved high-order 2D elements on a Riemannian plane. To this end, we measure the deviation of a given 2D element, straight-sided or curved, from the stretching ...
  • Lattice-Based proof of a shuffle 

    Costa, Nuria; Martínez Pinilla, Ramiro; Morillo Bosch, M. Paz (2019)
    Conference report
    Open Access
    In this paper we present the first fully post-quantum proof of a shuffle for RLWE encryption schemes. Shuffles are commonly used to construct mixing networks (mix-nets), a key element to ensure anonymity in many applications ...
  • Transportation noise (in particular railway noise) and blood pressure in REGICOR compared to SAPALDIA 

    Foraster, María; Basagaña Flores, Xavier; Aguilera, Inmaculada; Agis Cherta, David; Bouso, Laura; Phuleria, Harish; Dratva, Julia; Probst-Hensch, Nicole; Schindler, Christian; Künzli, Nino; Elosua, Roberto; Rivera, Marcela; Deltell, Alexandre (2012)

  • Cross-sectional association between road traffic noise and hypertension in a population-based sample in Girona, Spain (REGICOR-AIR project) 

    Foraster, María; Basagaña Flores, Xavier; Aguilera, Inmaculada; Rivera, Marcela; Agis Cherta, David; Bouso, Laura; Deltell, Alexandre; Dratva, Julia; Juvinyà, Dolors; Sunyer, Jordi; Elosua, Roberto; Künzli, Nino (International Institute of Acoustics and Vibration, 2011)

  • Disentangling the effects of traffic-related noise and air pollution on blood pressure: indoor noise levels and protections 

    Foraster, María; Basagaña Flores, Xavier; Aguilera, Inmaculada; Rivera, Marcela; Agis Cherta, David; Bouso, Laura; Deltell, Alexandre; Elosua, Roberto; Künzli, Nino (2013)
    Conference report
    Open Access
    Outdoor road traffic noise levels are associated with hypertension (HT). Studies on blood pressure (BP) are inconsistent and the true indoor traffic noise exposure may differ due to protections against noise. We analysed ...
  • RLWE-Based Zero-Knowledge Proofs for Linear and Multiplicative Relations 

    Martínez Pinilla, Ramiro; Morillo Bosch, M. Paz (Springer International Publishing, 2019)
    Conference report
    Restricted access - publisher's policy
    We present efficient Zero-Knowledge Proofs of Knowledge (ZKPoK) for linear and multiplicative relations among secret messages hidden as Ring Learning With Errors (RLWE) samples. Messages are polynomials in $\mathbb{Z}_q[ ...
