Memory and long-range correlations in chess games
(2014)In this paper we report the existence of long-range memory in the opening moves of a chronologically ordered set of chess games using an extensive chess database. We used two mapping rules to build discrete time series and ... -
Obstacles modelling reality: two exploratory studies on physics defined and undefined problems
(2014)One important skill to be developed in future physicists is modelling reality using physics. Problem-solving is the activity most used to teach, learn and assess physics skills at the university level. However, most of the ... -
Improving furosemide polymorphs properties through supramolecular complexes of beta-cyclodextrin
(2014)In this work, complexes of β-cyclodextrin and the two solid forms of furosemide were prepared and characterized for their potential pharmaceutical applications, with the interactions between the two compounds being studied ... -
Silver L1, L2 and L3 cross-sections for ionization and x-ray production by electron impact
(2014)The experimental determination of ionization cross-sections and total x-ray production cross-sections under electron impact is carried out for the three silver L-subshells. The very complex spectral structure involving ... -
Air core notch-coil magnet with variable geometry for fast-field-cycling NMR
(2015)In this manuscript we present details on the optimization, construction and performance of a wide-bore (71 mm) a-helical-cut notch-coil magnet with variable geometry for fast-field-cycling NMR. In addition to the usual ... -
Influence of β-cyclodextrin on the Properties of Norfloxacin Form A
(2014-12-16)Cyclodextrins are able to form host-guest complexes with hydrophobic molecules to result in the formation of inclusion complexes. The complex formation between norfloxacin form A and β-cyclodextrin was studied by exploring ... -
Spherical functions associated with the three dimensional sphere
(2014)In this paper, we determine all irreducible spherical functions of any K-type associated to the pair (G;K) = (SO(4); SO(3)). This is accomplished by associating to a vector valued function H = H(u) of a real variable ... -
Weighted estimates for integral operators on local BMO type spaces
(2015)We prove the weighted boundedness for a family of integral operators Tα on Lebesgue spaces and local BMO type spaces. To this end we show that Tα can be controlled by the Calder ́on operator and a local maximal operator. ... -
Pure type systems with explicit substitutions
(2015)We introduce a new formulation of pure type systems (PTSs) with explicit substitution and de Bruijn indices and formally prove some of its meta-theory. Using techniques based on Normalisation by Evaluation, we prove that ... -
Monte Carlo simulation of characteristic secondary fluorescence in electron probe microanalysis of homogeneous samples using the splitting technique
(2015)Electron probe microanalysis (EPMA) is based on the comparison of characteristic intensities induced by monoenergetic electrons. When the electron beam ionizes inner atomic shells and these ionizations cause the emission ... -
Information extraction with active learning : a case study in legal text
(2015)Active learning has been successfully applied to a number of NLP tasks. In this paper, we present a study on Information Extraction for natural language licenses that need to be translated to RDF. The final purpose of our ... -
Depth distribution of martensite in plasma nitrided AISI H13 steel and its correlation to hardness
(2015)The depth distributions of hardness, nitrogen, and crystallographic phases in the diffusion zone of plasma nitrided AISI H13 steel were determined by microindentation, electron microprobe, grazing incidence X-ray diffraction, ... -
Spherical functions : the spheres vs the projective spaces
(2014)In this paper we establish a close relationship between the spherical functions of the n-dimensional sphere Sn ≃ SO(n + 1)/SO(n) and the spherical functions of the n-dimensional real projective space P n(R) ≃ SO(n + ... -
Rare event simulation with fully automated Importance splitting
(2015)Probabilistic model checking is a powerful tool for analysing probabilistic systems but it can only be efficiently applied to Markov models. Monte Carlo simulation provides an alternative for the generality of stochastic ... -
Smart sampling for lightweight verification of Markov decision processes
(2015)Markov decision processes (MDP) are useful to model optimisation problems in concurrent systems. To verify MDPs with efficient Monte Carlo techniques requires that their nondeterminism be resolved by a scheduler. Recent ... -
Stopping power of palladium for protons in the energy range 0.300-3.100 MeV
(2013)The stopping power of palladium for protons has been measured using the transmission method with an overall uncertainty of around 5% over the energy range Ep=(0.300–3.100) MeV. These stopping power data are then compared ... -
A statistical study of heterogeneous nucleation of ice by molecular dynamics
(2015)We studied the stochastic nature of heterogeneous nucleation of supercooled liquid water by molecular dynamics simulations. The systems were composed of 768 molecules; M of them had their positions restricted forming a ... -
From a systems theory of sociology to modeling the onset and evolution of criminality
(2015)This paper proposes a systems theory approach to the modeling of onset and evolution of criminality in a territory. This approach aims at capturing the complexity features of social systems. Complexity is related to the ... -
A multivariate geostatistical approach for landscape classification from remotely sensed image data
(2015)This paper proposes a methodology to address the classification of images that have been acquired from remote sensors. One common problem in classification is the high dimensionality of multivariate characteristics. The ... -
First-principles studies of lithium storage in reduced graphite oxide
(2014-09)The present work performs a first-principles study of the lithiation of graphite oxides with low oxygencontent, which resemble reduced graphite oxide materials. The chemical nature of the Li structure formedis analysed, ...
