Multi-Start Methods
(Springer, 2018-08-27)
[EN]Multi-start procedures were originally conceived as a way to exploit a local or neighborhood search procedure, by simply applying it from multiple random initial solutions. Modern multi-start methods usually incorporate ...
A Tunable Generator of Instances of Permutation-Based Combinatorial Optimization Problems
(2016-04)
[EN]In this paper, we propose a tunable generator of instances of permutation-based Combinatorial Optimization Problems. Our approach is based on a probabilistic model for permutations, called the Generalized Mallows model. ...
An Evaluation of Methods for Estimating the Number of Local Optima in Combinatorial Optimization Problems
(MIT Press, 2013-11-01)
[EN] The solution of many combinatorial optimization problems is carried out by metaheuristics, which generally make use of local search algorithms. These algorithms use some kind of neighborhood structure over the search ...
Methodology for determining the threshold distance for estimating the main EM exposure contribution in WLAN
(Elsevier, 2021-05-25)
The location of radiation sources in wireless networks is a key factor to characterize their contribution to electromagnetic exposure levels in order to deploy future networks that account for minimizing electromagnetic ...
Characterizing in-band full-duplex in broadcast communications: From field trials to a loopback channel model
(Elsevier, 2024-04-27)
In-band full duplex (IBFD) communications are a potential solution to spectrum scarcity. IBFD communications offer greater spectral efficiency than traditional half-duplex communications by transmitting and receiving on ...
Wearable Slot Antenna at 2.45 GHz for Off-Body Radiation: Analysis of Efficiency,Frequency Shift, and Body Absorption
(Wiley, 2017-09-12)
The interaction of body-worn antennas with the human body causes a significant decrease in antenna efficiency and a shift in resonant frequency. A resonant slot in a small conductive box placed on the body has been shown ...
A molecular perspective on the emergence of long-range polar order from an isotropic fluid
(Elsevier, 2024-06-06)
The ferroelectric nematic phase (NF) has quickly become the most studied system in liquid crystal research. In this work, we investigate the origin of such polar structure by studying a compound for which the NF phase ...
Euskal eskoletan bigarren hezkuntzako ikasleen komunikazio hizkuntza-antsietate eta komunikatzeko-borondate prozesuetan generoa aztertzen
(2024-03-07)
Eskuarteko doktore tesiaren xede nagusi da euskal testuinguru eleanitz konplexuan Komunikazio Hizkuntza-antsietatearen (KHA) eta Komunikazio-borondatearen (KB) arteko harremana aztertzea eta faktore hauek generoarekin duten ...
Dielectric spectroscopy of a ferroelectric nematic liquid crystal and the effect of the sample thickness
(Elsevier, 2023-10)
The recently discovered ferroelectric nematic liquid crystals have been reported to exhibit very large dielectric permittivity values. Here, we report a systematic investigation of the dielectric behavior of a prototypical ...
On the toughening and crystallization behaviour of aliphatic biopolyesters
(2024-03-08)
In this doctoral thesis, two biopolyesters, polylactide (PLA) and poly(¿-caprolactone) (PCL) were studied with the aim of improving their properties and broadening their applications. The studied polymeric samples and ...
