      Article
      Accés obert
      Multi-FPGA platforms, like Amazon AWS F1, can run in the cloud multikernel pipelined applications, like convolutional neural networks (CNNs), with excellent performance and lower energy consumption than CPUs or GPUs. We ...
    • Dynamics of solar radiation pressure-assisted maneuvers between lissajous orbits 

      Stefania, Soldini; Masdemont Soler, Josep; Gómez Muntané, Gerard (2019-04-01)
      Article
      Accés obert
      The analysis of the phase space geometry around the artificial L1,2 equilibrium points of the circular restricted three-body problem, including solar radiation pressure, is used to investigate “propellant-free” transfers ...
    • Fractal analysis of growing cities and its relationship with health centre 

      Leyton, Carolina; Redondo Apraiz, José Manuel; Tarquis Alfonso, Ana Maria; Gil Martín, Joan Carles; Tellez Alvarez, Jackson David (Moscow Institute of Physics and Technology (MIPT), 2017-06-06)
      Article
      Accés obert
      During recent years, many research group interested in the study of organizational networks from different fields, e.g. studies of behavior of cities growth following the fractal theory. Considering the fractal analysis ...
    • Non-linear set-membership identification approach based on the Bayesian framework 

      Fernández Canti, Rosa M.; Tornil Sin, Sebastián; Blesa Izquierdo, Joaquim; Puig Cayuela, Vicenç (2015-06-06)
      Article
      Accés obert
      This study deals with the problem of set-membership identification of non-linear-in-the-parameters models. To solve this problem, this study illustrates how the Bayesian approach can be used to determine the feasible ...
    • Nonlinear moving horizon estimator for online estimation of the density and viscosity of a mineral slurry 

      Diaz Castañeda, Jenny Lorena; Ocampo-Martínez, Carlos; Alvarez, Hernan (2017-12-13)
      Article
      Accés obert
      This paper proposes a moving horizon estimator for nonlinear systems with unknown inputs, which do not comply with the model structures proposed in the literature for the design of nonlinear observers. The estimator is ...
    • On the compatibility of classical multiplier estimates with variable reduction techniques when there are nonlinear inequality constraints 

      Mijangos, Eugenio; Nabona Francisco, Narcís (Institut d'Estadística de Catalunya, 1999)
      Article
      Accés obert
      The minimization of a nonlinear function subject to linear and nonlinear equality constraints and simple bounds can be performed through minimizing a partial augmented Lagrangian function subject only to linear constraints ...
    • Optimising the extraction rate of a non-durable non-renewable resource in a monopolistic market: a mathematical programming approach 

      Corominas Subias, Albert; Fossas Colet, Enric (Springer, 2015-09-17)
      Article
      Accés obert
      We assume a monopolistic market for a non-durable non-renewable resource such as crude oil, phosphates or fossil water. Stating the problem of obtaining optimal policies on extraction and pricing of the resource as a ...
