El informe integrado: una propuesta de encaje para la información sobre capital humano
(CEIPA, 2014-01-20)
La manera de informar de las empresas presenta algunos problemas (Lizcano,
2011), tanto en relación con la cantidad y complejidad de normas, como con la calidad de
la información corporativa que divulga cada compañía. ...
Hydrogenation of sunflower oil over M/SiO2 and M/Al2O3 (M = Ni, Pd, Pt, Co, Cu) catalysts
(Springer, 2016-03-11)
This work is aimed at evaluating the performance of several catalysts in the partial hydrogenation of sunflower oil. The catalysts are composed of noble (Pd and Pt) and base metals (Ni, Co and Cu), supported on both silica ...
Brønsted Base Catalyzed One-Pot Synthesis od Stereodefined Six-Member Carbocycles Featuring Transient Trienolates and a Key Intramolecular 1,6-Addition
(Wiley-VCH, 2019-07-31)
Acatalyst-driven one-pot reaction sequence is
developed for the enantio- and diastereoselective synthesis of
tetrasubstituted cyclohexenes from simple unsaturated ketones
or thioesters.The method involves atertiary ...
RF Energy Absorption in Human Bodies Due to Wearable Antennas in the 2.4 GHz Frequency Band
(Wiley, 2019-11-19)
Human exposure to electromagnetic fields produced by two wearable antennas operating in the 2.4 GHz frequency band was assessed by computational tools. Both antennas were designed to be attached to the skin, but they were ...
Klimari buruzko negoziazioak, Kyotoko Protokoloa ordezkatuko duen akordio baterako: Kopenhageko porrotetik Parisko Akordiora
(UEU, 2017-11-30)
Kyotoko Protokoloa ordezkatuko duen akordio loteslea lortzeko negoziazioak
2007an hasi ziren. 2009ko Kopenhageko Konferentziaren porrotaren ondoren,
negoziazioak bertan behera geratu ziren, eta ez zen ia aurrerapenik ...
El papel de la Unión Europea en la consecución de un acuerdo sustitutivo del Protocolo de Kioto: de Bali a París
(Instituto de Estudios Europeos de la Universidad de Valladolid, 2016)
La lucha contra el cambio climático es un elemento fundamental de la política europea de medio ambiente pues posibilita la consecución de un desarrollo sostenible. Durante la última década la Unión Europea ha desarrollado ...
Europako Ingurumen Zuzenbidearen oinarrien eta printzipioen eboluzioa eta egungo egoera: Tratatuak, Ekintza Programak eta Estrategiak

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 ...
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 ...
