An aircraft combination wheelchair seat suitable for aircraft aisles
(2020-05-30)
Article
Accés obertAir travel is very restricted for individuals with mobility limitations and there is a need for the design of improved accommodation for individuals in wheelchairs on an aircraft. The aim of this paper is to present an ... -
An algebraic approach to lifts of digraphs
(2019-09)
Article
Accés obertWe study the relationship between two key concepts in the theory of (di)graphs: the quotient digraph, and the lift Ga of a base (voltage) digraph. These techniques contract or expand a given digraph in order to study its ... -
An algebraic fractal approach to Collatz Conjecture
(Universitat Politècnica de Catalunya, 2019-05)
Treball Final de Grau
Accés obertThe Collatz conjecture is one of the most easy-to-state unsolved problems in Mathematics today. It states that after a finite number of iterations of the Collatz function, defined by C(n) = n/2 if n is even, and by C(n) = ... -
An algebraic framework for Diffie-Hellman assumptions
(2017-01)
Article
Accés obertWe put forward a new algebraic framework to generalize and analyze Di e-Hellman like Decisional Assumptions which allows us to argue about security and applications by considering only algebraic properties. Our D`;k-MDDH ... -

An Algebraic framework for the definition of compositional semantics of normal logic programs
(1997-11)
Report de recerca
Accés obertThe aim of our work is the definition of compositional semantics for modular units over the class of normal logic programs. In this sense, we propose a declarative semantics for normal logic programs in terms of model ... -
An algebraic model for the storage of data in parallel memories
(Springer, 1989)
Capítol de llibre
Accés obertThe use of SIMD computers requires efficient schemes of storage of data in order to have conflict-free acces in parallel computation. In this paper we restate the problem of finding such chemes in an algebraic context. ... -
An algebraic parameter estimation approach to the adaptive observer-controller based regulation of the boost converter
(Institute of Electrical and Electronics Engineers, 2007-06)
Text en actes de congrés
Accés obertIn this article, a new approach is proposed for the problem of output voltage reference trajectory tracking in a boost converter with unknown, piecewise constant, load resistance values, under the restriction of noisy ... -
An algebraic view of the relation between largest common subtrees and smallest common supertrees
(2004-12)
Report de recerca
Accés obertThe relationship between two important problems in tree pattern matching, the largest common subtree and the smallest common supertree of two trees, is established by means of simple constructions, which allow one to obtain ... -
An algorithm for a bi-objective parallel machine problem with eligibility, release dates and delivery times of the jobs
(2016-01-01)
Article
Accés obertThe scheduling of parallel machines is a well-known problem in many companies. Nevertheless, not always all the jobs can be manufactured in any machine and the eligibility appears. Based on a real-life problem, we present ... -
An algorithm for a biobjective parallel machine problem with eligibility and release and delivery times
(2012)
Text en actes de congrés
Accés restringit per política de l'editorialThe scheduling of parallel machines is a well-known problem in many companies. Nevertheless, not always all the jobs can be manufactured in any machine and the eligibility appears. Based on a real-life situation, we present ... -
An algorithm for beat-to-beat heart rate detection from the BCG based on the continuous spline wavelet transform
(2016-05-01)
Article
Accés obertThis work describes an algorithm intended to detect the beat-to-beat heart rate from the ballistocardiogram (BCG) obtained from seated subjects. The algorithm is based on the continuous wavelet transform with splines, which ... -

An Algorithm for k-Anonymous Microaggregation and Clustering Inspired by the Design of Distortion-Optimized Quantizers
(Elsevier Science Ltd., 2011)
Article
Accés restringit per política de l'editorialWe present a multidisciplinary solution to the problems of anonymous microaggregation and clustering, illustrated with two applications, namely privacy protection in databases, and private retrieval of location-based ... -
An algorithm for mesh refinement and un-refinement in fast transient dynamics
(2013-08)
Article
Accés obertA procedure to locally refine and un-refine an unstructured computational grid of four-node quadrilaterals (in 2D) or of eight-node hexahedra (in 3D) is presented. The chosen refinement strategy generates only elements of ... -
An algorithm for simulation of concrete cable-stayed bridges built on temporary supports and considering time dependent effects
(2014-11)
Article
Accés restringit per política de l'editorialThe time-dependent phenomena effects might play an important role in the structural behavior of a cable-stayed bridge during construction and in service. In fact, because of these effects the target state of stresses ... -
An algorithm for the microaggregation problem using column generation
(2022-08-01)
Article
Accés obertThe field of statistical disclosure control aims to reduce the risk of re-identifying an individual from disseminated data, a major concern among national statistical agencies. Operations Research (OR) techniques have been ... -
