description: We describe the astrometric reduction of images obtained with the FORS2/VLT camera in the framework of an astrometric planet search around 20 M/L-transition dwarfs. We present the correction of systematic errors, the achieved astrometric performance, and a new astrometric catalogue containing the faint reference stars in 20 fields located close to the Galactic plane. We detected three types of systematic errors in the FORS2 astrometry: the relative motion of the camera's two CCD chips, errors that are correlated in space, and an error contribution of yet unexplained origin. The relative CCD motion has probably a thermal origin and usually is 0.001-0.010 px (~0.1-1 mas), but sometimes amounts to 0.02-0.05 px (3-6 mas). This instability and space-correlated errors are detected and mitigated using reference stars. The third component of unknown origin has an amplitude of 0.03-0.14 mas and is independent of the observing conditions. We find that a consecutive sequence of 32 images of a well-exposed star over 40 min at 0.6" seeing results in a median r.m.s. of the epoch residuals of 0.126 mas. Overall, the epoch residuals are distributed according to a normal law with a chi2~1. We compiled a catalogue of 12000 stars with I-band magnitudes of 16-22 located in 20 fields, each covering ~2x2'. It contains I-band magnitudes, ICRF positions with 40-70 mas precision, and relative proper motions and absolute trigonometric parallaxes with a precision of 0.1 mas/yr and 0.1 mas at the bright end, respectively.

description: Notre travail propose de mettre en lumière les liens complémentaires existant entre le français langue seconde et l’orientation professionnelle dans les classes d’accueil de l’Ecole de la transition. Nous nous sommes interrogés sur les enjeux spécifiques de ces deux domaines et nous avons également tenté de clarifier les rôles respectifs des professionnels qui interviennent ensemble pendant les périodes de coaching. Notre démarche s’inscrit dans le cadre théorique de la didactique du français langue seconde. Les notions théoriques sur lesquelles nous nous sommes appuyées sont la perspective actionnelle et les genres de texte. Nous avons au préalable décrit en détail le cadre institutionnel très particulier des classes d’accueil de l’Ecole de la transition. Nous avons aussi cherché à définir le terme de coaching et à décrire le plus précisément possible le travail des conseillers en orientation en classe d’accueil. Pour notre recherche, nous nous sommes basés sur le Portfolio, sorte de « manuel de l’orientation professionnelle » distribué à tous les élèves de l’Ecole de la transition, pour effectuer un travail d’observation, par lequel nous avons cherché à identifier et analyser les difficultés des élèves allophones dans leur parcours d’orientation professionnelle. Nous avons choisi d’utiliser la typologie des objectifs communicationnels de la didactique des langues secondes pour répertorier et analyser les difficultés des élèves allophones : difficultés de type discursif, socio-culturel, lexical, morpho-sytaxique et phonétique. Pour chacun de ces types de difficulté, nous avons sélectionné des activités du Portfolio qui nous paraissaient les plus représentatives. Nous les avons analysées en nous demandant quels pourraient être les apports de la didactique du français langue seconde pour contourner les obstacles rencontrés par nos élèves. Nous avons ainsi pu faire une série de propositions d’alternatives et de remédiations. Ce travail nous a permis de mettre en lumière les bénéfices que le français langue seconde retire des situations concrètes qui jalonnent le parcours de l’orientation professionnelle et qui constituent une réelle source de motivation dans l’apprentissage de la langue.
title: 2D numerical simulation of vessels advancing in level ice and ice management operations
Creators: name: Hassanin, Ahmed
Publisher: name: Memorial University of Newfoundland
Year: 2023

description: This thesis provides a hybrid, numerical and semi-empirical model that predicts ship-ice interaction in level ice. In addition, the model is integrated into an existing software solution, allowing for the simulation of ice management operations and vessel control in sea ice environments. The software implementation numerically solves for contact surfaces between the ship and ice in the time domain and utilizes semi-empirical formulas to estimate the ice forces generated in the interaction. A new method that does not remove rubble ice from the simulation is proposed. The addition of broken ice floes and increased ice shape complexity is facilitated by applying polygon partitioning and simplification algorithms to allow for a an adjustable trade-off between accuracy and performance. The software solution is validated using the data from model-scale tests and-full scale trials. Finally, recommendations for future work to improve upon the proposed model are provided.

description: We discuss the lambda phi**4 model in 2- and 3-dimensional non-commutative spaces. The mapping onto a Hermitian matrix model enables its non-perturbative investigation by Monte Carlo simulations. The numerical results reveal a phase where stripe patterns dominate. In d=3 we show that in this phase the dispersion relation is deformed in the IR regime, in agreement with the property of UV/IR mixing. This "striped phase" also occurs in d=2. For both dimensions we provide evidence that it persists in the simultaneous limit to the continuum and to infinite volume ("Double Scaling Limit"). This implies the spontaneous breaking of translation symmetry.

description: O sistema educativo se divide em sucessivas camadas, passando pela escola e a turma até chegar, no seu âmago, aos grupos de colegas. A dinâmica destes grupos, que pode opor-se ao processo educativo, com frequência é opaca para os educadores. Por isso, este trabalho resenhou pesquisas sobre grupos de alunos adolescentes e aproveitamento em 18 países. Os resultados, desde as investigações pioneiras, mostram que os adolescentes, nas sociedades industriais e pós-industriais, formam suas subculturas, em busca de autonomia e protagonismo, com frequência distanciando-se das culturas escolares. Conforme os respectivos valores dominantes, os grupos podem estimular ou não o aproveitamento, o que torna questão sensível o agrupamento dos estudantes por escola e turma. As constatações, neste sentido, sugerem maiores vantagens para a diversidade. A escola, com as suas feições burocráticas e industriais, necessita de profundas mudanças para fazer face a estas realidades, relacionadas com a violência e a indisciplina, o que precisa ser contemplado pela formação de educadores, para deixar de ser um ponto cego.

description: Las relaciones interpersonales que se dan en la escuela son de fundamental importancia para el desarrollo de los niños y adolescentes, sin embargo, cuando estas relaciones se institucionalizan a partir de las normas implícitas o explícitas, se pueden desencadenar situaciones que alteren la convivencia escolar. Partiendo de esa idea, se realizó un estudio exploratorio que tuvo como objetivo conocer las percepciones de las niñas y niños acerca de las situaciones en las interacciones maestro- alumno, que generan una convivencia escolar inadecuada. Se realizó una encuesta a 2711 estudiantes de primaria y secundaria de la ciudad de Querétaro (México). Los resultados muestran que para los encuestados los factores asociados a las relaciones interpersonales maestro-alumno y los factores asociados a la enseñanza como dar clases aburridas son significativos para que se presenten situaciones que alteran la convivencia escolar.

description: Extrasolar planet searches targeting very low-mass stars and brown dwarfs are hampered by intrinsic or instrumental limitations. Time series of astrometric measurements with precisions better than one milli-arcsecond can yield new evidence on the planet occurrence around these objects. We present first results of an astrometric search for planets around 20 nearby dwarf stars with spectral types M8-L2. Over a timespan of two years, we obtained I-band images of the target fields with the FORS2 camera at the Very Large Telescope. Using background stars as references, we monitored the targets' astrometric trajectories, which allowed us to measure parallax and proper motions, set limits on the presence of planets, and to discover the orbital motions of two binary systems. We determined trigonometric parallaxes with an average accuracy of 0.09 mas (~0.2 %) resulting in a reference sample for the study of ultracool dwarfs at the M/L transition, whose members are located at distances of 9.5-40 pc. This sample contains two newly discovered tight binaries (DE0630-18 and DE0823-49) and one previously known wide binary (DE1520-44). Only one target shows I-band variability >5 mmag r.m.s. We derived planet exclusion limits that set an upper limit of 9 % to the occurrence of giant planets with masses >5 MJup in intermediate-separation (0.01-0.8 AU) orbits around M8-L2 dwarfs. We demonstrated that astrometric observations with an accuracy of 120 micro-arcsec over two years are feasible from the ground and can be used for a planet search survey. The detection of two tight very low-mass binaries showed that our search strategy is efficient and may lead to the detection of planetary-mass companions through follow-up observations.

description: UNESCO Associated Schools (ASPnet) hold great potential for addressing issues of violence whether at the school or community level or beyond. This study of ASPnet schools in Brazil, Canada and Mozambique suggests that these schools’ focus on strengthening the mechanisms of democracy, inclusive citizenship, and conflict transformation that creates a particularly effective dialogic space for critically and collectively engaging with conflict. The study contextualizes the UNESCO ASPnet projects in relation to creating a culture of peace, provides current data collected through interviews with over 100 school teachers, administrators, parents and students. The investigation suggests that UNESCO ASPnet schools provide ways of overcoming violence and transforming conflict through attention to human rights, democracy, respect for diversity, and global perspectives on sustainability and world issues.

description: In this work it is introduced the notion of regular Fredholm pair, i.e. a Fredholm pair whose operators are regular. The main properties of these objects are studied, and what is more, they are entirely classified. Furthermore, the index of a Fredholm pair turns out to be an extremely useful tool in the description of the aforementioned objects. Finally, regular Fredholm pairs are characterized in terms of regular Fredholm symmetrical pairs, exact chains of multiplication operators, and invertible Banach space operators.

description: L’enjeu de ce mémoire est de cerner l’effet d’un enseignement sur la problématique des stéréotypes sociaux et de la définition du concept de genre sur les élèves de classes de 9P et 10P, donc des élèves de 11 à 14 ans. L’objectif de ce travail porte sur une prise en compte de la diversité et de la complexité sociale dans laquelle des individus évoluent. Pour ce faire, l’étude s’articule autour d’une séquence d’enseignement : une introduction au genre de 45 minutes mêlant activités et réflexions. Grâce à des questionnaires soumis aux élèves, nous évaluons leurs connaissances et croyances sur les différences entre les sexes. Puis progressivement, se déroule une explication visant à leur faire comprendre que sexe biologique et identité de genre sont deux choses distinctes, l’une innée et l’autre acquise au cours de notre développement culturel et social. Finalement, une discussion sur les stéréotypes de genre permet de donner des exemples concrets des inégalités liées à notre système de classification des sexes. Ce mémoire permet de répondre à une interrogation récurrente : face à une telle déconstruction de leur système de valeur, les élèves pourraient-ils potentiellement être perturbés dans le développement de leur identité sexuée ? Cette étude répond aussi à des questions telles que, face à une introduction au concept de genre, quelles sont les réponses rencontrées ? Les élèves interrogés sont-ils dérangés, choqués par la distinction entre sexe biologique et genre en tant que construction sociale ? Mesurer l’impact de cet enseignement permet de légitimer des cours centrés sur le genre à l’école, et de définir si ce type d’« initiations au genre » est une méthode qui pourrait être envisagée afin de parler concrètement des stéréotypes en classe avec un cadre théorique précis.

description: We summarize what large surveys of the contemporary universe have taught us about the physics and phenomenology of the processes that link the formation and evolution of galaxies and their central supermassive black holes. We present a picture in which the population of AGN can be divided into two distinct populations. The Radiative-Mode AGN are associated with black holes that produce radiant energy powered by accretion at rates in excess of ~1% of the Eddington Limit. They are primarily associated with less massive black holes growing in high-density pseudo-bulges at a rate sufficient to produce the total mass budget in these black holes in ~10 Gyr. The circum-nuclear environment contains high density cold gas and associated star-formation. Major mergers are not the primary mechanism for transporting this gas inward; secular processes appear dominant. Stellar feedback will be generic in these objects and strong AGN feedback is seen only in the most powerful AGN. In Jet-Mode AGN the bulk of energetic output takes the form of collimated outflows (jets). These AGN are associated with the more massive black holes in more massive (classical) bulges and elliptical galaxies. Neither the accretion onto these black holes nor star-formation in their host bulge is significant today. These AGN are probably fueled by the accretion of slowly cooling hot gas that is limited by the feedback/heating provided by AGN radio sources. Surveys of the high-redshift universe are painting a similar picture. (Abridged).

description: This paper aims at empirically testing the dynamics of budget outcomes of Italian municipalities in the aftermath of floods, by accounting for heterogeneous levels of resilience and vulnerability to natural disasters. Our findings, based on a dynamic difference-in-difference after propensity score matching, point to substantial impacts in terms of increased capital expenditure and revenues from transfer, which also depend on the degree of resilience and vulnerability. Through our analysis we account for multiple aspects of risk so we can support policy decisions related to both ex-ante and ex-post disaster occurrence management.

description: The present article reports a method for the average grain size evaluation of superconducting nano-particles through their magnetic properties. The use of SQUID magnetometry to determine the average MgB2 particle size was investigated and the results compared with those achieved through other techniques. In particular the data obtained from zero field cooled magnetization measurement as function of the temperature were compared with the results obtained by scanning electron microscopy and Brunauer-Emmett-Teller techniques. The particle magnetization was measured by a commercial SQUID magnetometer in magnetic field (1 mT) and temperatures ranging from 5 to 50 K dispersing the powders in a grease medium. The grain size is obtained by fitting the data taking into account the Ginzburg-Landau temperature dependence of the London penetration depth. Variations on typical modeling parameters were explored in order to gain a better picture of the average grain size and the effectiveness of various measurement techniques. We find that it is possible to use the magnetization measurements to determine the average grain size even if the SEM image analysis allows extracting more information about the grain size distribution. Furthermore a Matlab routine has been developed in order to get automatic analysis of SEM images.

description: There have been a number of attempts to derive the set of quantum non-local correlations from reasonable physical principles. Here we introduce $\tilde{Q}$, a set of multipartite supra-quantum correlations that has appeared under different names in fields as diverse as graph theory, quantum gravity and quantum information science. We argue that $\tilde{Q}$ may correspond to the set of correlations of a reasonable physical theory, in which case the research program to reconstruct quantum theory from device-independent principles is met with strong obstacles. In support of this conjecture, we prove that $\tilde{Q}$ is closed under classical operations and satisfies the physical principles of Non-Trivial Communication Complexity, No Advantage for Nonlocal Computation, Macroscopic Locality and Local Orthogonality. We also review numerical evidence that almost quantum correlations satisfy Information Causality.

description: No âmbito do projeto “Sexualidade e género no discurso dos media: implicações socioeducacionais e desenvolvimento de uma alternativa na formação de professores/as” realizado no Centro de Investigação Didática e Tecnologia na Formação de Formadores da Universidade de Aveiro, foram analisados pela equipa de investigação e por outras investigadoras envolvidas em projetos de mestrado e de doutoramento, anúncios publicitários, videojogos, séries televisivas, desenhos animados, revistas, jornais e videoclips. Para cada um dos media objeto de estudo desenharam-se e implementaram-se dispositivos metodológicos de questionamento dos conteúdos de sexualidade e género presentes no currículo cultural. Elaboraram-se guiões didáticos, utilizados  e validados numa oficina de formação de professores/as. Os resultados obtidos permitem constatar que os media analisados veiculam representações de sexualidade e género; que naturalizam estereótipos e formas de dominação; que as crianças e jovens aderem a uma educação que integre questões de sexualidade e media no currículo escolar; e que os/as professores/as, quando sensibilizados para a temática, sentem que a sua abordagem educativa se torna premente.
Esta comunicação ao divulgar os resultados do referido projeto, pretende ainda sinalizar uma outra problemática, no quadro de uma educação em sexualidade  que privilegie a saúde e o respeito pelos direitos humanos – a hipersexualização do espaço público – enquanto fenómeno social e mediático que afeta sobretudo crianças e jovens do sexo feminino.

description: Using the framework of stochastic thermodynamics, we present an experimental study of a doublet of magnetic colloidal particles which is manipulated by a time-dependent magnetic field. Due to hydrodynamic interactions, each bead experiences a state-dependent friction, which we characterize using a hydrodynamic model. In this work, we compare two estimates of the dissipation in this system: the first one is energy based since it relies on the measured interaction potential, while the second one is information based since it uses only the information content of the trajectories. While the latter only offers a lower bound of the former, we find it to be simple to implement and of general applicability to more complex systems.

description: O homem sempre acalentou o sonho de decifrar o segredo da eternidade. Imaginou a existência de seres superiores imunes às leis da morte. Chamou-lhes deuses e heróis. Através dos mitos, tentou explicar os fenómenos naturais. As religiões sistematizaram essas histórias e reuniram-nas nos livros sagrados, arautos divinos de terras prometidas em paraísos celestiais de difícil e incerto acesso.

As utopias literárias idearam paraísos terrestres situados em futuros possíveis à luz dos conhecimentos científicos disponíveis. A. Huxley e M. Houellebecq abordam o tema da imortalidade no Brave New World (1932) e em La possibilité d’une île (2005). Como epopeias dramáticas que são, oferecem-nos uma dupla miragem de eterna juventude no admirável mundo novo e de eterno retorno na possibilidade duma ilha.

description: Spin-orbit interactions lead to small energy gaps between the outer-most $p_{1/2}$ and $p_{3/2}$ shells of noble gas atoms. Strong-field pulses tunnel-ionize an electron out of either shell resulting in spin-orbit-driven hole motion. These hole dynamics affect the HHG yield. However, the spectral shape as well as the angular distribution of the HHG emission is not influenced by spin-orbit coupling. We demonstrate the spin-orbit effect on atomic krypton by solving the multi-electron Schrödinger equation with the time-dependent configuration-interaction singles (TDCIS) approach. We also provide pulse parameters where this effect can be identified in experiments through an enhancement in the HHG yield as the wavelength of the strong-field pulse increases.

description: We report on the determination of micromagnetic parameters of epilayers of the ferromagnetic semiconductor (Ga,Mn)As, which has easy axis in the sample plane, and (Ga,Mn)(As,P) which has easy axis perpendicular to the sample plane. We use an optical analog of ferromagnetic resonance where the laser-pulse-induced precession of magnetization is measured directly in the time domain. By the analysis of a single set of pump-and-probe magneto-optical data we determined the magnetic anisotropy fields, the spin stiffness and the Gilbert damping constant in these two materials. We show that incorporation of 10% of phosphorus in (Ga,Mn)As with 6% of manganese leads not only to the expected sign change of the perpendicular to plane anisotropy field but also to an increase of the Gilbert damping and to a reduction of the spin stiffness. The observed changes in the micromagnetic parameters upon incorporating P in (Ga,Mn)As are consistent with the reduced hole density, conductivity, and Curie temperature of the (Ga,Mn)(As,P) material. We report that the magnetization precession damping is stronger for the n = 1 spin wave resonance mode than for the n = 0 uniform magnetization precession mode.

description: A investigação mais recente no campo da neurofisiologia recorrendo à ressonância magnética pôs em causa as nossas conceções do visual. A pesquisa foi levada a cabo por Shinji Nishimoto e Jack Gallant, da Universidade da Califórnia em Berkeley, que recorreram à imagiologia por ressonância magnética funcional (fMRI) e a modelos computacionais não só para mapear as áreas específicas do cérebro que respondem aos estímulos visuais, mas também, ao inverterem o processo, para reconstruir as imagens geradas no cérebro. Este avanço científico e tecnológico levanta importantes questões acerca do modo como nos relacionamos com a imagem (por exemplo, numa perspetiva fenomenológica), assim como acerca do papel da imaginação nas sociedades contemporâneas (do ângulo dos estudos culturais). Este artigo visa discutir o impacte que estas formas de interface entre a tecnologia e o corpo humano podem ter no contexto da cultura visual do século XXI. Será que esta objetivação da nossa capacidade de gerar imagens destruirá as nossas crenças na inefabilidade do processo criativo? Será que oferece a oportunidade de explorar outros domínios de expressão artística e de desenvolvimento cultural nas sociedades contemporâneas, onde as gerações mais novas estão tão marcadas pela hiper-realidade e pelo digital?

Ciência, público e compreensão pública da ciência

description: O conhecimento científico é, porventura, o elemento caraterístico das sociedades atuais mais distintivo destas relativamente a épocas passadas. No entanto, o défice de compreensão de temas científicos pelo público em geral é enorme e muitos, senão a maioria, não sabe situar questões sócio-científicas e interpretar argumentos a favor ou contra. Posições filosóficas, sociológicas e éticas levam a que se questione os limites entre o que é tecnicamente possível e aquilo que é eticamente admissível. É neste contexto que se considera ciência e cidadania como domínios da intervenção humana profundamente interligados, sobre os quais se ocupam muitas organizações internacionais reclamando para a educação formal propósitos de organização de currículos, programas e estratégias que consolidem tal interligação.

Se a ciência está na sociedade e é para a sociedade como transpor esta perspetiva para a ciência escolar? Ciência para a cidadania será uma orientação para disciplinas optativas ou deverá ser uma perspetiva de ciência para todos? Como conciliar no ensino formal a educação científica do público em geral e a de futuros cientistas? Defendendo-se que a ciência faz parte da cultura importa analisar referenciais de organização do ensino das ciências numa perspetiva humanista que permitam a todos alcançar saberes, competências e atitudes que os habilitem a enfrentar questões presentes na discussão pública e que condicionam decisões políticas nas sociedades democráticas.

description: Motivado pela recente controvérsia levantada pela realização de exames de acesso à profissão docente, imposta pelo Ministério da Educação de Portugal, o autor decidiu reflectir sobre alguns dos «lugares comuns», escutados com frequência em debates sobre a «escola», o «ensino» e os «professores», tentando fornecer algumas defesas contra a arma de arremesso que os mesmos constituem, quando utilizados por aqueles que, ou não reflectiram sobre o assunto, ou estão providos de má-fé, actuando de acordo com as conveniências de ocasião.

description: This research aims to know the teaching behaviors of primary teachers and their students, as well as to know the dominant behavioral categories in teachers’ dealings with students during physical education and sports lessons, according to the Flanders system for measuring classroom interaction.The study was based on the hypothesis that the teaching level of primary education teachers during the physical education and physical education session differs from the percentages set by Flanders.The study sample consisted of eight teachers from some primary schools in the state of Khenchela, selected purposefully due to the facilities provided by their administrations and the significant cooperation of the teachers working. The researcher employed adescriptive-analytical approach in the study and used both the mean and percentage as statistical methods.These methods allowed the researcher to assess the feasibility of using Flanders System for measuringteaching behaviours in physical education classes

description: The treatment of radiation transport in global circulation models (GCMs) is crucial to correctly describe Earth and exoplanet atmospheric dynamics processes. The two-stream approximation and correlated-k method are currently state-of-the-art approximations applied in both Earth and hot Jupiter GCM radiation schemes to facilitate rapid calculation of fluxes and heating rates. Their accuracy have been tested extensively for Earth-like conditions, but verification of the methods' applicability to hot Jupiter-like conditions is lacking in the literature. We are adapting the UK Met Office GCM, the Unified Model (UM), for the study of hot Jupiters, and present in this work the adaptation of the Edwards-Slingo radiation scheme based on the two-stream approximation and the correlated-k method. We discuss the calculation of absorption coefficients from high temperature line lists and highlight the large uncertainty in the pressure-broadened line widths. We compare fluxes and heating rates obtained with our adapted scheme to more accurate discrete ordinate (DO) line-by-line (LbL) calculations ignoring scattering effects. We find that, in most cases, errors stay below 10 % for both heating rates and fluxes using ~ 10 k-coefficients in each band and a diffusivity factor D = 1.66. The two-stream approximation and the correlated-k method both contribute non-negligibly to the total error. We also find that using band-averaged absorption coefficients, which have previously been used in radiative-hydrodynamical simulations of a hot Jupiter, may yield errors of ~ 100 %, and should thus be used with caution.

description: O artigo fundamenta-se em investigadores (Almeida, 2011; Galvão & Reis, 2008; Hilário & Reis, 2009; Reis, 1999, 2007, 2013) que argumentam que a discussão de temas controversos é relevante na educação em Ciências dos cidadãos, devido ao seu potencial para a construção de uma imagem mais real e humana da atividade científica. Assim, a abordagem de temas controversos poderá contribuir para a aprendizagem das Ciências (do seu conteúdo, processos e natureza) bem como para o desenvolvimento cognitivo, social, político, moral e ético dos alunos. Por outro lado, o livro didático é um instrumento ainda muito mais presente do que se desejaria no cotidiano do professor da escola básica brasileira, constituindo-se em importante material de aprendizagem e fonte de conhecimentos para os estudantes, sendo muitas vezes, a única fonte de informações disponível. Diante disso, a investigação teve como objetivo verificar a abordagem que os temas controversos apresentam em livros didáticos brasileiros utilizados durante os estágios supervisionados em curso de Ciências Biológicas. A investigação se caracteriza como qualitativa do tipo análise documental e teve como amostra os livros didáticos de Ciências e de Biologia utilizados nos últimos cinco anos (2008-2012). Os resultados indicam que há uma crescente melhoria na forma como os temas controversos são abordados nos livros didáticos mais atuais. Contudo, o estudo sobre essa abordagem tem-se revelado essencial em processos de intervenção capazes de apoiar os professores no planejamento e na implementação de atividades de discussão desses temas para a consecução dos objetivos do currículo de Ciências e de Biologia.

description: Game extension is an entertaining activity that offers an opportunity to test new design approaches by non-programmers. The real challenge is to enable this activity by means of a suitable infrastructure. We propose a knowledge-driven approach with natural game-player concepts. These concepts, found in game ontologies, include game abstractions and rules for game moves. The approach has been implemented and tested for board games. These include tic-tac-toe as a simplest example, enabling extensions of tic-tac- toe, say to a four-by-four board and Sudoku, a single player game of a very different nature.
