Statics and dynamics of weakly coupled antiferromagnetic spin-1/2 ladders in a magnetic field
2011
We investigate weakly coupled spin-1/2 ladders in a magnetic field. The work is motivated by recent experiments on the compound (C5H12N)2CuBr4 (BPCB). We use a combination of numerical and analytical methods, in particular the density matrix renormalization group (DMRG) technique, to explore the phase diagram and the excitation spectra of such a system. We give detailed results on the temperature dependence of the magnetization and the specific heat, and the magnetic field dependence of the nuclear magnetic resonance (NMR) relaxation rate of single ladders. For coupled ladders, treating the weak interladder coupling within a mean-field or quantum Monte Carlo approach, we compute the transit…
On modal mu-calculus over finite graphs with bounded strongly connected components.
2010
For every positive integer k we consider the class SCCk of all finite graphs whose strongly connected components have size at most k. We show that for every k, the Modal mu-Calculus fixpoint hierarchy on SCCk collapses to the level Delta2, but not to Comp(Sigma1,Pi1) (compositions of formulas of level Sigma1 and Pi1). This contrasts with the class of all graphs, where Delta2=Comp(Sigma1,Pi1).

La Llegenda del cor menjat al Decameró de Boccaccio: Estratègies de traducció al català
2013
Resum: El grau d’intervencio del traductor determina l’acostament del text al lector. Amb la comparacio de les quatre traduccions catalanes de La llegenda del cor menjat , el conte nove de la quarta jornada del Decamero de Giovanni Boccaccio, es pot comprovar que cada traductor utilitza estrategies diferents per mirar de resoldre un mateix problema de traduccio. A mes del bagatge cultural i la subjectivitat de cada un d’ells, cal tenir en compte un seguit de factors (temporals, historics, referencials, lingu?istics, socials, etc.) que determinen el resultat final. Paraules clau: llegenda; cor; menjat; Decamero ; Boccaccio; estrategia de traduccio Abstract: The extent to which translators in…
Editorial – Preface to the Special Issue on Numerical Techniques Meet with OR
2021
Abstract This special issue of the Foundations of Computing and Decision Sciences, titled ”Numerical Techniques Meet with OR”, is devoted to the numerical techniques and their applications in real-world phenomena. The special issue and its editorial present numerical algorithms as they meet with different research topics such as, e.g., from operational research, supply chain management, geometrical structures and Covid-19 effects on financial applications. Besides, the special issue covers instructional information about numerical techniques which are useful for OR research problems and real-world applications on such issues.
Two View Line-Based Motion and Structure Estimation for Planar Scenes
2012
We present an algorithm for reconstruction of piece-wise planar scenes from only two views and based on minimum line correspondences. We first recover camera rotation by matching vanishing points based on the methods already exist in the literature and then recover the camera translation by searching among a family of hypothesized planes passing through one line. Unlike algorithms based on line segments, the presented algorithm does not require an overlap between two line segments or more that one line correspon- dence across more than two views to recover the translation and achieves the goal by exploiting photometric constraints of the surface around the line. Experimental results on real…
The Peace Treaty of Fredrikshamn and its Aftermath in Sweden and Finland
2010
This article analyses the Peace Treaty of Fredrikshamn (Hamina in Finnish) and its consequences in Sweden and Finland. The Russians set strict preconditions for the commencement of peace negotiations with the Swedes in the summer of 1809. These conditions were realized almost <em>in toto</em> in the final peace treaty, which consisted of just twenty-one articles. In addition to regulations directly related to the ending of hostilities, the main provisions of the agreement entailed huge territorial losses for Sweden, strictly defining the regions it was to cede to Russia, the most important of which was Finland. Sweden was also enjoined to give up its alliance with Britain and to…

Evidence for thermal equilibration in multifragmentation reactions probed with bremsstrahlung photons
2001
The production of nuclear bremsstrahlung photons (E$_{\gamma}>$ 30 MeV) has been studied in inclusive and exclusive measurements in four heavy-ion reactions at 60{\it A} MeV. The measured photon spectra, angular distributions and multiplicities indicate that a significant part of the hard-photons are emitted in secondary nucleon-nucleon collisions from a thermally equilibrated system. The observation of the thermal component in multi-fragment $^{36}$Ar+$^{197}$Au reactions suggests that the breakup of the thermalized source produced in this system occurs on a rather long time-scale.
