A new approach to gross error detection for GPS networks
(2019-05-29)
Article
Open AccessWe present a new matrix-based approach to detect and correct gross errors in GPS geodetic control networks. The study is carried out by introducing a new matrix, whose entries are powers of a (real or complex) variable, ... -
A posteriori error estimation for standard finite element analysis
(1998-09)
Article
Open AccessA new residual type estimator based on projections of the error on subspaces of locally-supported functions is presented. The estimator is defined by a standard element-by-element refinement. First, an approximation of the ... -

Calibration techniques of interferometric microwave receivers
(Universitat Politècnica de Catalunya, 2017-10-18)
Bachelor thesis
Restricted access - author's decisionAn interferometer for orbital determination receives a satellite signal at different spatial points using antennas that form a baseline. Those received signals have a different phase which is related to the distance between ... -
Computing the expected Markov reward rates with stationarity detection and relative error control
(Kluwer Academic Publishers, 2016-03-11)
Article
Open AccessBy combining in a novel way the randomization method with the stationary detection technique, we develop two new algorithms for the computation of the expected reward rates of finite, irreducible Markov reward models, with ... -

Enhanced equal frequency partition method for the identification of a water demand system
(Sarjoughian,H.S.; Cellier, F.E.; Marefat, M.M.; Rozenblit, J.W. (eds.) Institute of Electrical and Electronics Engineers, 2000)
Conference report
Open AccessThis paper deals with unsupervised partitioning. A first goal of this paper is to present an enhancement to the Equal Frequency Partition (EFP) method that allows to reduce, to some extent, the main drawback of this classical ... -
Equilibrated patch recovery error estimates: simple and accurate upper bounds of the error
(Wiley and Sons, 2007-03)
Article
Open AccessThis paper introduces a new recovery-type error estimator ensuring local equilibrium and yielding a guaranteed upper bound of the error. The upper bound property requires the recovered solution to be both statically ... -
Error analysis in two-terminal impedance measurements with residual correction
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2005-10-31)
Article
Open AccessResidual impedance correction in impedance analyzers when using an asymmetrical test fixture needs three reference measurements, usually open circuit, short circuit, and load (meaning an impedance close to the impedance ... -
Error analysis of programmable metasurfaces for beam steering
(2020-03-01)
Article
Open AccessRecent years have seen the emergence of programmable metasurfaces, where the user can modify the electromagnetic (EM) response of the device via software. Adding reconfigurability to the already powerful EM capabilities ... -
k-NN algorithm appled todata association and data fusion in multi-sensor multi-target OFDM radar scenarios
(Universitat Politècnica de Catalunya, 2020-06)
Bachelor thesis
24 months embargoIn the recent years, numerous Machine Learning investigations have been centered around the topic of point-target positioning and tracking, which rises the interest for algorithms such as k-NN to be implemented for said ... -
MASkIt: soft error rate estimation for combinatorial circuits
(Institute of Electrical and Electronics Engineers (IEEE), 2016)
Conference report
Restricted access - publisher's policyIntegrated circuits are getting increasingly vulnerable to soft errors; as a consequence, soft error rate (SER) estimation has become an important and very challenging goal. In this work, a novel approach for SER estimation ... -

Covenantee: Chalmers tekniska högskolaOne of the major challenges for energy companies is to adapt their process plants to the continuous improvements of available technologies, so as to make their old plants as competitive and cost-efficient as the new ones. ... -
Recovering lower bounds of the error by postprocessing implicit residual a posteriori error estimates
(2003-03)
Article
Open AccessClassical residual type error estimators approximate the error flux around the elements and yield upper bounds of the exact (or reference) error. Lower bounds of the error are also needed in goal oriented adaptivity and ... -
Subdomain-based flux-free a posteriori error estimators
