Innovative straight formulation for plate in bending
2017
In this paper it has been introduced an innovative formulation for evaluating the deflection function of a simply supported plate loaded by uniformly distributed edge moments. Framed into Line Element-less Method, this formulation allows the evaluation of solution in terms of deflection, through few lines of algorithm implemented by Mathematica software without resorting to any discretization neither in the domain nor in the boundary. Interesting savings in terms of time and computational costs are achieved. Results obtained by the proposed method are well contrasted by ones obtained by classical methods and Finite Element Method.
Steiner systems and configurations of points
2020
AbstractThe aim of this paper is to make a connection between design theory and algebraic geometry/commutative algebra. In particular, given any Steiner SystemS(t, n, v) we associate two ideals, in a suitable polynomial ring, defining a Steiner configuration of points and its Complement. We focus on the latter, studying its homological invariants, such as Hilbert Function and Betti numbers. We also study symbolic and regular powers associated to the ideal defining a Complement of a Steiner configuration of points, finding its Waldschmidt constant, regularity, bounds on its resurgence and asymptotic resurgence. We also compute the parameters of linear codes associated to any Steiner configur…
Fault detection for discrete-time Markov jump linear systems with partially known transition probabilities
2010
In this article, the fault detection (FD) problem for a class of discrete-time Markov jump linear system (MJLS) with partially known transition probabilities is investigated. The proposed systems are more general, which relax the traditional assumption in Markov jump systems that all the transition probabilities must be completely known. A residual generator is constructed and the corresponding FD is formulated as an H ∞ filtering problem by which the error between residual and fault are minimised in the H ∞ sense. The linear matrix inequality-based sufficient conditions for the existence of FD filter are derived. A numerical example on a multiplier–accelerator model economic system is give…
EDUCATIONAL IMPLICATIONS OF CONTACT BETWEEN CULTURES
2010
Monográfico con el título: 'Perspectiva educativa y cultural de 'juego de rol'. Resumen basado en el de la publicación La presencia de alumnado extranjero constituye un hecho evidente en los centros escolares en España y se debe tener en cuenta al planificar cualquier intervención educativa. Ante esta situación, hay que replantearse la estructuración y organización escolar de cara a dar respuestas adecuadas a la diversidad cultural y lingüística. A partir de una investigación llevada a cabo sobre la educación bilingüe en California, se plantean algunas reflexiones que conviene tener en consideración a la hora de trabajar en contextos escolares de diversidad cultural y lingüística. Recurrien…
'Tell Us Only What You Know': Evidentiality in the Discourse of Participants in Spanish Trials
2019
El objetivo de esta propuesta es explorar el uso de la evidencialidad en los juicios españoles y su relación con las convenciones del género y los roles de los participantes en estos eventos discursivos. Para ello, basamos nuestro estudio en un análisis cuantitativo-cualitativo de un corpus transcrito de ensayos orales en español. La evidencialidad es una categoría semántico-funcional que incluye dispositivos lingüísticos que marcan la fuente de información detrás de las declaraciones del hablante. El marcado explícito de la fuente no es obligatorio en español; sin embargo, en géneros específicos (legal, parlamentario y académico), se convierte en una poderosa herramienta argumentativa para…
Cognitive factors in the evaluation of synthetic speech
1998
Abstract This paper illustrates the importance of various cognitive factors involved in perceiving and comprehending synthetic speech. It includes findings drawn from the relative psychological and psycholinguistic literature together with experimental results obtained at the Fondazione Ugo Bordoni laboratory. Overall, it is shown that listening to and comprehending synthetic voices is more difficult than with a natural voice. However, and more importantly, this difficulty can and does decrease with the subjects' exposure to said synthetic voices. Furthermore, greater workload demands are associated with synthetic speech and subjects listening to synthetic passages are required to pay more …
CSCL – a tool to motivate foreign language learners: The Finnish application
2003
This article discusses the applications of the theory of Computer Supported Collaborative Learning (CSCL) to teaching and learning a foreign language, in this case, one of the ‘Less Commonly Taught Languages’, Finnish. The ‘Virtually Finnish’ project was based on the idea of creating a larger, virtual Finnish learning community among the second-year Finnish language students in five US universities during the fall semester, 2001. CSCL was chosen as a base, as its principal goal is to aid the learners in sharing and distributing their knowledge to the whole learning community. In addition to discussing the set up and the content of the project, the students’ feedback about their language lea…
MODULAR KNOWLEDGE REPRESENTATION IN ADVISOR AGENTS FOR SITUATION AWARENESS
2011
A modular knowledge representation framework for conversational agents is presented. The approach has been realized to suit the situation awareness paradigm. The modularity of the framework makes possible the composition of specific modules that deal with particular features, simplifying both the chatbot design process and its smartness. As a proof of concepts we have developed a modular, situation awareness oriented, KB for a conversational agent, which plays the role of an advisor aimed at helping a user to be in charge of a virtual town, inspired to the SimCity series game. The agent makes an extensive use of semantic computing techniques and is able to perceive, comprehend and project c…
Developing creativity through ICT and Music Teachers’ Training: a biographical experience
2021
O texto faz parte de uma investigação qualitativa biográfico-narrativa que temos em curso, e que se processa mediante a obtenção de testemunhos de professores e investigadores que formam professores com o auxílio das TIC de modo a promover as competências de criatividade, colaboração, cooperação e comunicação, entendidas como essenciais para o desenvolvimento de uma educação integral, promotora da sustentabilidade curricular e da cidadania participativa. Neste artigo, damos conta da experiência de uma professora e investigadora, Cristina Arriaga Sanz, que se dedica à formação de professores no âmbito da Educação Musical no ensino superior espanhol, de que salientaremos a relação estreita co…
Abstract Syntax as Interlingua: Scaling Up the Grammatical Framework from Controlled Languages to Robust Pipelines
2020
Abstract syntax is an interlingual representation used in compilers. Grammatical Framework (GF) applies the abstract syntax idea to natural languages. The development of GF started in 1998, first as a tool for controlled language implementations, where it has gained an established position in both academic and commercial projects. GF provides grammar resources for over 40 languages, enabling accurate generation and translation, as well as grammar engineering tools and components for mobile and Web applications. On the research side, the focus in the last ten years has been on scaling up GF to wide-coverage language processing. The concept of abstract syntax offers a unified view on many oth…
