A comparison of high-order time integrators for thermal convection in rotating spherical shells
(2010-10-01)
Article
Accés obertA numerical study of several time integration methods for solving the threedimensional Boussinesq thermal convection equations in rotating spherical shells is presented. Implicit and semi-implicit time integration ... -
A technique to composite a modified Newton's method for solving nonlinear equations
(2011-05-02)
Report de recerca
Accés obertA zero-finding technique for solving nonlinear equations more efficiently than they usually are with traditional iterative methods in which the order of convergence is improved is presented. The key idea in deriving this ... -
Aligning modeled and observed behavior: A compromise between computation complexity and quality
(Springer, 2017)
Text en actes de congrés
Accés obertCertifying that a process model is aligned with the real process executions is perhaps the most desired feature a process model may have: aligned process models are crucial for organizations, since strategic decisions can ... -
Constructing frozen Jacobian iterative methods for solving systems of nonlinear equations, associated with ODEs and PDEs using the homotopy
(2016-03-01)
Article
Accés obertA homotopy method is presented for the construction of frozen Jacobian iterative methods. The frozen Jacobian iterative methods are attractive because the inversion of the Jacobian is performed in terms of LUfactorization ... -
Convergence and stability assessment of Newton-Kantorovich reconstrutin algorithms for microwve tomography
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1998-08-31)
Article
Accés obertFor newly developed iterative Newton-Kantorovitch reconstruction techniques, the quality of the final image depends on both experimental and model noise. Experimental noise is inherent to any experimental acquisition scheme, ... -
Fast analysis and optimization of sparsely distributed partial modification problems
(Institute of Electrical and Electronics Engineers (IEEE), 2022-08)
Article
Accés obertThis article addresses the efficient numerical analysis of sparsely distributed small modifications in a large structure, that is, the sparsely distributed partial modification problem (SDPMP). A hierarchical matrix ... -
Iterative Learning Control for homing guidance design of missiles
(Elsevier, 2017-02-16)
Article
Accés obertThis paper presents an Iterative Learning Control design applied to homing guidance of missiles against maneuvering targets. According to numerical experiments, although an increase of the control energies is appreciated ... -
Nonlinear actuation model for lateral electrostatically-actuated DC-contact RF MEMS series switches.
(JOHN WILEY & SONS INC, 2007-06-01)
Article
Accés obertIn this work, a nonlinear model to predict actuation characteristics in lateral electrostatically-actuated DC-contact MEMS switches is proposed. In this case a parallel-plate approximation cannot be applied. The model ... -
On computational order of convergence of some multi-precision solvers of nonlinear systems of equations
(2011-05-02)
Report de recerca
Accés obertIn this paper the local order of convergence used in iterative methods to solve nonlinear systems of equations is revisited, where shorter alternative analytic proofs of the order based on developments of multilineal ... -
Optimized query forgery for private information retrieval
(2010-09)
Article
Accés obertWe present a mathematical formulation for the optimization of query forgery for private information retrieval, in the sense that the privacy risk is minimized for a given traffic and processing overhead. The privacy ... -
The Koch monopole: a small fractal antenna
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2000-11)
Article
Accés obertFractal objects have some unique geometrical properties. One of them is the possibility to enclose in a finite area an infinitely long curve. The resulting curve is highly convoluted being nowhere differentiable. One such ... -
Un esquema paralelo para el cálculo del pseudoespectro de matrices de gran magnitud
(Universitat Politècnica de Catalunya. CIMNE, 2015-01-01)
Article
Accés obertEl pseudoespectro es una gran herramienta para el estudio de sistemas dinámicos asociados a matrices no normales. En las últimas décadas su estudio y aplicación se ha intensificado, por lo que realizar su cálculo de forma ...
