Year: 2005

description: A regeneração de cidades a partir de projectos de desporto, de cultura e turismo tem sido um instrumento estratégico utilizado ao nível internacional e nacional, por municípios e entidades privadas, para o relançamento e diferenciação das suas sociedades. O património cultural assume-se, cada vez mais, como elemento estratégico de gestão e planeamento das cidades. O turismo associou-se ao património cultural, oferecendo uma grande variedade de produtos culturais. No entanto, esta relação de associação entre turismo e património tem sido bastante questionada. A sustentabilidade do turismo com base nos recursos culturais e patrimoniais pressupõe a definição de estratégias e políticas integradas, em que o património cultural seja considerado um elo agregador do passado colectivo da comunidade. Os debates correntes na gestão do património cultural como recurso turístico, apontam para os seguintes problemas principais: risco de 'musificação-banalização', competição do espaço urbano, desertificação do centro histórico, terciarização, gentrificação, perda de autenticidade, sustentabilidade do turismo cultural e capacidade de carga. Para fazer face aos riscos criados por fluxos turísticos excessivos existem, na actualidade, múltiplos meios de acção susceptíveis de serem colocados em prática, de forma isolada ou complementar, e que se integram no que se designou por técnicas de gestão de visitantes. O trabalho de investigação de base foi aplicado aos estudos de caso de Faro e Silves, e caracteriza-se como uma abordagem pela oferta. Procurar-se-á apresentar de forma resumida os seus resultados, centrando-se a análise nas práticas de gestão do património cultural, com vista ao turismo destas cidades, bem como as preocupações emergentes (à data de 2001).

description: First-principles calculations reveal a large cooperative coupling of Jahn-Teller (JT) distortion to oxygen-octahedron rotations in perovskite LaMnO$_3$. The combination of the two distortions is responsible for stabilizing the strongly orthorhombic $A$-AFM insulating ($I$) $Pbnm$ ground state relative to a metallic ferromagnetic (FM-$M$) phase. However, epitaxial strain due to coherent matching to a crystalline substrate can change the relative stability of the two states. In particular, coherent matching to a square-lattice substrate favors the less orthorhombic FM-$M$ phase, with the $A$-AFM phase stabilized at higher values of tensile epitaxial strain due to its larger volume per formula unit, resulting in a coupled magnetic and metal-insulator transition at a critical strain close to 1%. At the phase boundary, colossal magneto-resistance is expected. Tensile epitaxial strain enhances the JT distortion and opens the band gap in the $A$-AFM-$I$ $c$-$Pbnm$ phase, offering the opportunity for band-gap engineering. Compressive epitaxial strain induces an orientational transition within the FM-$M$ phase from $c$-$Pbnm$ to $ab$-$Pbnm$ with a change in the direction of the magnetic easy axis relative to the substrate, yielding strain-controlled magnetization at the phase boundary. The strong couplings between the JT distortion, the oxygen-octahedron rotations and the magnetic and electronic properties, and associated functional behavior, motivate interest in other orthorhombic $Pbnm$ perovskites with large JT distortions, which should also exhibit a rich variety of coupled magnetic, structural and electronic phase transitions driven by epitaxial strain.

description: This work describes the implementation of a genetic algorithm-based strategy combined with first-principles computations for identifying the structure of the most stable boron 1D structures. We focus our attention on the structure of ultrathin 1D boron structures given the lack of previous experimental and theoretical work on this topic. Our methodology yields reasonable structural candidates for further optimizations at the DFT level with tighter convergence criteria. The simulations involved 1D structures with up to 8 atoms per unit cell. We have identified four main groups of structures: flat nanowires (monatomic-height stripes) with triangular or triangular and "square" motifs, stripes with larger holes, nanowires with an open tubular shape, and regular nanowires. The diameter-dependent structural changes are discussed.

We predict a strong hydrodynamics-induced generic violation of the Wiedeman-Franz law in bulk 2D GaAs systems for mobilities as modest as $10^6 \mathrm{cm}^2/Vs$ and densities $1$-$5\times10^{11} \mathrm{cm}^{-2}$ in the temperature range of $T=1$-$40K$.

The inclusion size is much smaller than the array period while the wavelength is fixed. We derive and rigorously justify the dispersion relation for general frequencies and show that there are exceptional frequencies for which the solution is a cluster of waves propagating in different directions with different frequencies so that the dispersion relation cannot be defined uniquely. Examples are provided for the spherical inclusions.

description: Many physical systems are described by partial differential equations (PDEs). Determinism then requires the Cauchy problem to be well-posed. Even when the Cauchy problem is well-posed for generic Cauchy data, there may exist characteristic Cauchy data. Characteristics of PDEs play an important role both in Mathematics and in Physics. I will review the theory of characteristics and bicharacteristics of PDEs, with a special emphasis on intrinsic aspects, i.e., those aspects which are invariant under general changes of coordinates. After a basically analytic introduction, I will pass to a modern, geometric point of view, presenting characteristics within the jet space approach to PDEs. In particular, I will discuss the relationship between characteristics and singularities of solutions and observe that: "wave-fronts are characteristic surfaces and propagate along bicharacteristics". This remark may be understood as a mathematical formulation of the wave/particle duality in optics and/or quantum mechanics. The content of the paper reflects the three hour minicourse that I gave at the XXII International Fall Workshop on Geometry and Physics, September 2-5, 2013, Evora, Portugal.

description: Geometrically frustrated clusters of Ising spins of different shapes on a triangular lattice are studied by exact enumeration and Monte Carlo simulation. The focus is laid on the ground-state energy and residual entropy behaviors as functions of the cluster shape and size, as well as the spin value. Depending on the cluster shape, the residual entropy density on approach to the thermodynamic limit can either vanish or remain finite and the dependence can be decreasing, increasing or non-monotonic. Nevertheless, the relative entropies normalized by the respective thermodynamic limit values turn out to be little sensitive to the spin value. Some interesting finite-temperature properties of the clusters are also discussed and attention is drawn to their magnetocaloric properties.

description: In this paper, we propose two strategies for decreasing the error of arbitrary single-mode Gaussian transformations implemented using one-way quantum computation on a four-node linear cluster state. We show that it is possible to minimize the error of the arbitrary single-mode Gaussian transformation by a proper choice of the weight coefficients of the cluster state. We modify the computation scheme by adding a non-Gaussian state obtained using a cubic phase gate as one of the nodes of the cluster. This further decreases the computation error. We evaluate the efficiencies of the proposed optimization schemes comparing the probabilities of the error correction of the quantum computations with and without optimizations. We have shown that for some transformations, the error probability can be reduced by up to 900 times.

description: Generating axion dark matter through the kinetic misalignment mechanism implies the generation of large asymmetries for Standard Model fermions in the early universe. Even if these asymmetries are washed out at later times, they can trigger a chiral plasma instability in the early universe. Similarly, a direct coupling of the axion with the hypercharge gauge field can trigger a tachyonic instability. These instabilities produce helical magnetic fields, which are preserved until the electroweak phase transition. At the electroweak phase transition, these become a source of baryon asymmetry, which can be much more efficient than the original axiogenesis proposal. We discuss constraints on axion dark matter production from the overproduction of the baryon asymmetry as well as a minimal, albeit fine-tuned setup, where both the correct dark matter abundance and baryon asymmetry can be achieved. For a given axion decay constant, this leads to a sharp prediction for the mass of the radial direction of the Peccei Quinn field, which is a soft mass scale in supersymmetric theories.

description: Large sparse circuits of spiking neurons exhibit a balanced state of highly irregular activity under a wide range of conditions. It occurs likewise in sparsely connected random networks that receive excitatory external inputs and recurrent inhibition as well as in networks with mixed recurrent inhibition and excitation. Here we analytically investigate this irregular dynamics in finite networks keeping track of all individual spike times and the identities of individual neurons. For delayed, purely inhibitory interactions we show that the irregular dynamics is not chaotic but in fact stable. Moreover, we demonstrate that after long transients the dynamics converges towards periodic orbits and that every generic periodic orbit of these dynamical systems is stable. We investigate the collective irregular dynamics upon increasing the time scale of synaptic responses and upon iteratively replacing inhibitory by excitatory interactions. Whereas for small and moderate time scales as well as for few excitatory interactions, the dynamics stays stable, there is a smooth transition to chaos if the synaptic response becomes sufficiently slow (even in purely inhibitory networks) or the number of excitatory interactions becomes too large. These results indicate that chaotic and stable dynamics are equally capable of generating the irregular neuronal activity. More generally, chaos apparently is not essential for generating high irregularity of balanced activity, and we suggest that a mechanism different from chaos and stochasticity significantly contributes to irregular activity in cortical circuits.

description: An investigation of the critical behavior of strongly interacting QCD matter has been performed by analyzing fluctuation observables on event-by-event (ebe) basis measured in high-energy collision experiments. The fluctuation analysis is performed using nuclear interactions at different target sizes and at different colliding beam energies as a function of varying width of pseudorapidity interval. For the sake of comparison, event-by-event multiplicity fluctuations in hadronic and heavy-ion collisions (p-H, p-A and A-B) are studied within the framework of the Lund Monte Carlo based FRITIOF model. Charged particle multiplicity and the variance of the multiplicity distribution are estimated for the interactions involving different target sizes and beam momenta i.e., p-H, p-CNO, p-AgBr at 200A GeV/c and $^{16}$O-AgBr collisions at 14.6, 60 and 200A GeV/c. Further, multiplicity fluctuations are quantified in terms of intensive quantity, the scaled variances $ω$ and the strongly intensive quantity $Σ_{FB}$ derived from the charged particle multiplicity and the width of the multiplicity distribution. Strongly intensive quantity $Σ_{FB}$ is a quantity of great significance to extract information about short and long-range multiplicity correlations. Furthermore, the collision centrality and centrality bin width dependent behavior of the multiplicity fluctuation have been examined in the framework of Lund Monte Carlo based FRITIOF model. Results based on the fluctuation analysis carried out in the present study are interpreted in terms of dynamics of collision process and the possibility of related QCD phase transition.

description: In this paper we study and extend the mechanistic mean field theory of growth of cellular populations proposed by Mombach et al in (Mombach J. C. M. et al., Europhysics Letter, 59 (2002) 923) (MLBI model), and we demonstrate that the original model and our generalizations lead to inferences of biological interest. In the first part of this paper, we show that the model in study is widely general since it admits, as particular cases, the main phenomenological models of cellular growth. In the second part of this work, we generalize the \emph{MLBI} model to a wider family of models by allowing the cells to have a generic unspecified biologically plausible interaction. Then, we derive a relationship between this generic microscopic interaction function and the growth rate of the corresponding macroscopic model. Finally, we propose to use this relationship in order to help the investigation of the biological plausibility of phenomenological models of cancer growth.

description: We compare high-order methods including spectral difference (SD), flux reconstruction (FR), the entropy-stable discontinuous Galerkin spectral element method (ES-DGSEM), modal discontinuous Galerkin methods, and WENO to select the best candidate to simulate strong shock waves characteristic of hypersonic flows. We consider several benchmarks, including the Leblanc and modified shock-density wave interaction problems that require robust stabilization and positivity-preserving properties for a successful flow realization. We also perform simulations of the three-species Sod problem with simplified chemistry with the chemical reaction source terms introduced in the Euler equations. The ES-DGSEM scheme exhibits the highest stability, negligible numerical oscillations, and requires the least computational effort in resolving reactive flow regimes with strong shock waves. Therefore, we extend the ES-DGSEM to hypersonic Euler equations by deriving a new set of two-point entropy conservative fluxes for a five-species gas model. Stabilization for capturing strong shock waves occurs by blending high-order entropy conservative fluxes with low-order finite volume fluxes constructed using the HLLC Riemann solver. The hypersonic Euler solver is verified using the non-equilibrium chemistry Sod problem. To this end, we adopt the Mutation++ library to compute the reaction source terms, thermodynamic properties, and transport coefficients. We also investigate the effect of real chemistry versus ideal chemistry, and the results demonstrate that the ideal chemistry assumption fails at high temperatures, hence real chemistry must be employed for accurate predictions. Finally, we consider a viscous hypersonic flow problem to verify the transport coefficients and reaction source terms determined by the Mutation++ library.

description: We investigate the sub-Planck-scale structures associated with the SU(1,1) group by establishing that the Planck scale on the hyperbolic plane can be considered as the inverse of the Bargmann index $k$. Our discussion involves SU(1,1) versions of Wigner functions, and the quantum-interference effect is easily visualized through plots of these Wigner functions. Specifically, the superpositions of four Perelomov SU(1,1) coherent states (compass state) yield nearly isotropic sub-Planck structures in phase space scaling as $\frac1{k}$ compared with $\frac1{\sqrt{k}}$ scaling for individual SU(1,1) coherent states and anisotropic quadratically improved scaling for superpositions of two SU(1,1) coherent states (cat state). We show that displacement sensitivity exhibits the same quadratic improvement to scaling.

description: We show that the simultaneous modulation of the propagation constant and of the gain/loss coefficient along the multimode fibers results in unidirectional coupling among the modes, which, depending on the modulation parameters, leads to the enhancement or reduction of the excitation of higher order transverse modes. In the latter case, effective mode-cleaning is predicted, in ideal case resulting in single-mode spatially coherent output. The effect is semi-analytically predicted on a simplified Gaussian beam approximation and numerically proven by solving the wave propagation equation introducing the modulated potential.
Quaternary palaeochannel morphology as a function of palaeohydrology, SE Australia

description: The Murray-Darling Basin (MDB) of south-eastern Australia plays host to a vast array of river channels both modern and relict, comprising multiple distributive fluvial systems (DFS). On such systems in the MDB, morphologic and sedimentologic contrasts between contemporary channels and their respective palaeochannels have been utilized as evidence for hydrologic and climatic change throughout the late Quaternary, with prior studies suggesting palaeochannel evolution under a vastly larger discharge regime. This study mapped the bankfull width and meander wavelength of the modern and remnant Murrumbidgee and Macquarie rivers to determine the downstream evolution of (palaeo)channel morphology. Successive downstream channel measurements permitted a regression analysis which gave the approximate bankfull channel size at the apex of the DFS, alongside the rate of channel change with distance downstream. A transfer function was applied to estimate bankfull discharge from the head of the DFS, moving downstream in reaches. Downstream channel trends suggest the surveyed palaeochannels to be of similar planform to their modern rivers – single channel, laterally unconfined and of variable sinuosity – but operating on much larger scales. Comparison between the modern and surveyed palaeochannels suggests palaeochannels were formed under larger and highly variable bankfull discharges that dissipate with distance downstream and show agreement with a temperature-driven model that increased seasonal snowmelt and enhanced runoff efficiency during the last 20 ka to 80 ka.

description: As location-based techniques and applications become ubiquitous in emerging wireless networks, the verification of location information will become of growing importance. This has led in recent years to an explosion of activity related to location verification techniques in wireless networks, with a specific focus on Intelligent Transport Systems (ITS) being evident. Such focus is largely due to the mission-critical nature of vehicle location verification within the ITS scenario. In this work we review recent research in wireless location verification related to the vehicular network scenario. We particularly focus on location verification systems that rely on formal mathematical classification frameworks, showing how many systems are either partially or fully encompassed by such frameworks.
eTourism strategic and tactical impacts of information communication technologies for tourism
Creators: name: Buhalis, Dimitrios
Publisher: name: Journal of Tourism & Development
Year: 2004

description: ICTs stimulate radical changes in the operation, distribution and structure of the tourism industry. The proliferation of technology throughout the tourism distribution channels essentially means that both consumers and professionals use the newly available tools in order to retrieve information, identify suitable products and perform reservations. ICTs will increasingly determine the ability of principles to distribute their product efficiently and to communicate interactively with their clientele. ICTs can introduce great benefits to the efficiency, differentiation, cost reduction and response time of tourism organisations. Should tourism principals neglect the significance of ICTs in their distribution function, they will effectively jeopardise their competitiveness and become marginalised.

Year: 2004

description: Tourism has an important role in the former socialist East European Countries, with ideologists believing that travel and tourism have a positive feedback by diminishing the monotony and routine of employment. Romania has long been as important tourist destination, but interest in rural tourism has only developed strongly in recent years in the context of economic restructuring and land restitution. This paper examines the perceptions the potential Portuguese visitors might have about Romanis, as a rural tourist destination. A set of a preliminary findings based on the OPTOUR Project are presented.

description: We present efficient methods for Brillouin zone integration with a non-zero but possibly very small broadening factor $η$, focusing on cases in which downfolded Hamiltonians can be evaluated efficiently using Wannier interpolation. We describe robust, high-order accurate algorithms automating convergence to a user-specified error tolerance $\varepsilon$, emphasizing an efficient computational scaling with respect to $η$. After analyzing the standard equispaced integration method, applicable in the case of large broadening, we describe a simple iterated adaptive integration algorithm effective in the small $η$ regime. Its computational cost scales as $\mathcal{O}(\log^3(η^{-1}))$ as $η\to 0^+$ in three dimensions, as opposed to $\mathcal{O}(η^{-3})$ for equispaced integration. We argue that, by contrast, tree-based adaptive integration methods scale only as $\mathcal{O}(\log(η^{-1})/η^{2})$ for typical Brillouin zone integrals. In addition to its favorable scaling, the iterated adaptive algorithm is straightforward to implement, particularly for integration on the irreducible Brillouin zone, for which it avoids the tetrahedral meshes required for tree-based schemes. We illustrate the algorithms by calculating the spectral function of SrVO$_3$ with broadening on the meV scale.

description: We determined the frequency dependent effective permittivity of a large ternary network of randomly positioned resistors, capacitors, and diodes. A linear circuit analysis of such systems is shown to match the experimental dielectric response of single-walled carbon nanotube (SWCNT) filled polymers. This modeling method is able to reproduce the two most important features of SWCNT filled composites, i.e. the low frequency dispersion and dipolar relaxation. As a result of the modeling important physical conclusion proved by the experimental data was done: the low frequency behavior of SWCNT-filled polymer composites is mostly caused by the fraction of semiconducting SWCNTs.

description: We study the influence of non-local damping on magnon properties of Fe, Co, Ni and Fe$_{1-x}$Co$_{x}$ ($x=30\%,50\%$) alloys. The Gilbert damping parameter is typically considered as a local scalar both in experiment and in theoretical modelling. However, recent works have revealed that Gilbert damping is a non-local quantity that allows for energy dissipation between atomic sites. With the Gilbert damping parameters calculated from a state-of-the-art real-space electronic structure method, magnon lifetimes are evaluated from spin dynamics and linear response, where a good agreement is found between these two methods. It is found that non-local damping affects the magnon lifetimes in different ways depending on the system. Specifically, we find that in Fe, Co, and Ni the non-local damping decreases the magnon lifetimes, while in $\rm Fe_{70}Co_{30}$ and Fe$_{50}$Co$_{50}$ an opposite, non-local damping effect is observed, and our data show that it is much stronger in the former.
A interação entre o sector bancário e o turismo - os serviços e os turistas portugueses

Year: 2004

description: O turismo é um sector em crescimento, extremamente complexo e multifacetado, que interage com uma série de outro setores. A evolução dos produtos bancários, nomeadamente ao nível dos cartões d crédito, contribui enormemente para facilitar as viagens, quer em termos de segurança, quer em termos de comodidade e facilidade de pagamento, o que reforça a ideia de que a interacção entre o sector bancário e o turismo se faz sentir, essencialmente, ao nível das formas de pagamento disponibilizadas pelo primeiro. Os turistas portugueses continuam a usar, pincipalmente, o dinheiro independentemente da natureza das despesas, o que se prende com os seus hábitos de férias.

description: Defect dynamics in a thin active nematic layer is studied by asymptotic matching of solutions in the defect core and the far field. The analysis is facilitated by the correspondence between the 2D nematic and complex scalar field models. Self-propulsion and topological interactions are identified as the primary drivers of the defect motion, surpassing the influence of both passive backflow and active flow induced by other defects.
Avaliação do potencial de desenvolvimento turístico ao nível local - uma proposta de metodologia aplicada ao concelho de Ílhavo

Year: 2004

description: A elaboração de qualquer estratégia ou linha orientadora para o sector do turismo deverá passar pelo conhecimento da base de recursos que sustenta, ou que poderá sustentar, o desenvolvimento do turismo de um determinado local. A par do conhecimento dos recursos turísticos, há que se ter em conta também a procura, actual e potencial, por esses mesmos recursos. A interacção entre a oferta, elemento estático, e a procura, elemento dinâmico do sistema do turismo, faz surgir um terceiro elemento que deverá ser sempre ponderado quando se elabora uma estratégia de desenvolvimento: os impactes do turismo. O presente artigo, tendo por objectivo apresentar a metodologia seguida na avaliação do potencial de desenvolvimento do turismo a nível local, tenta evidenciar os três elementos que constituem o sistema do turismo.

description: Recent progress in network topology modeling [1], [2] has shown that it is possible to create smaller-scale replicas of large complex networks, like the Internet, while simultaneously preserving several important topological properties. However, the constructed replicas do not include notions of capacities and latencies, and the fundamental question of whether smaller networks can reproduce the performance of larger networks remains unanswered. We address this question in this letter, and show that it is possible to predict the performance of larger networks from smaller replicas, as long as the right link capacities and propagation delays are assigned to the replica's links. Our procedure is inspired by techniques introduced in [2] and combines a time-downscaling argument from [3]. We show that significant computational savings can be achieved when simulating smaller-scale replicas with TCP and UDP traffic, with simulation times being reduced by up to two orders of magnitude.
