    Automatic modeling of the linguistic values for database fuzzy querying

    Get PDF
    In order to evaluate vague queries, each linguistic term is considered according to its fuzzy model. Usually, the linguistic terms are defined as fuzzy sets, during a classical knowledge acquisition off-line process. But they can also be automatically extracted from the actual content of the database, by an online process. In at least two situations, automatically modeling the linguistic values would be very useful: first, to simplify the knowledge engineer’s task by extracting the definitions from the database content; and second, where mandatory, to dynamically define the linguistic values in complex criteria queries evaluation. Procedures to automatically extract the fuzzy model of the linguistic values from the existing data are presented in this paper

    Relative aggregation operator in database fuzzy querying

    Fuzzy selection criteria querying relational databases include vague terms; they usually refer linguistic values form the attribute linguistic domains, defined as fuzzy sets. Generally, when a vague query is processed, the definitions of vague terms must already exist in a knowledge base. But there are also cases when vague terms must be dynamically defined, when a particular operation is used to aggregate simple criteria in a complex selection. The paper presents a new aggregation operator and the corresponding algorithm to evaluate the fuzzy query

    Initiatives Towards an Education for Creativity

    AbstractWe have tried to approach the problem of fostering creativity in education from two distinct directions: First, in the project “iLab2 - Innovation Laboratories for the quality assurance of vocational education and training”, we acted on the learning environment. Then, in the project “Tecrino – teaching creativity in engineering”, we are working to create specially designed educational content for both teachers and students. This paper presents the philosophy and the preliminary results of these projects and suggests that a reformed school seems to be the only efficient social instrument for promoting creativity on a large scale

    'So Don't You Lock up Something / That You Wanted to See Fly'. What Story for Asylum Psychiatry?

    Get PDF
    In a rather long piece which an exhibition catalog has called „catholic propaganda”(Busch & Maisak, 2013, p. 342), Guido Görres reflected on madness and art, using Kaulbach’s iconic 1835 drawing of asylum inmates (Das Narrenhaus) as pretext. Görres wrote of “this hospital of the human spirit (…), this charnel ground of the living, who like specters roam, wearing on their foreheads the faded and almost illegible traces of their former names.”1(1836, p. 9). Overdramatic prose, but unlikely to strike one as unprecedented. If anything, it has long been customary to exhibit a mix of fascination and revulsion when discussing the institutions which in the past two centuries at the same time sheltered and shattered those deemed mentally ill

    Imperfect Data In Database Context. How Are They Stored In Extended Relational Databases

    Get PDF
    Building a more accurate reality model requires taking into account imperfect information present in our knowledge and language. This paper presents several aspects of data imperfection in the database context and the appropriate frameworks for their treatment. It’s concluding that null value, possibility distribution and probability theory are the best solutions to represent incomplete, imprecise and uncertain data. For each of these problems there are some relational model extension proposals, including data representation and relational algebra

    Urban green indicators: a tool to estimate the sustainability of our cities

    Full text link
    [EN] In Europe, more than 70% of the population lives in an urban area. All the challenges related to land use conflicts, demographic changes, climate resilience and human well-being are concentrated inside the cities, since the population is already living in urban areas, which are more and more compact and dependent on grey infrastructure. In this context, urban green infrastructure represents a sustainable solution to maintain the benefits and services provided by urban ecosystems and an efficient urban planning tool to face the urban challenges. The sustainability of our cities can be reached adopting an innovative vision using the concept of ecosystem services of the urban green infrastructure. Different initiatives to assess the benefits provided by green infrastructure have emerged in the last decade. However, very few take into account the whole range of services provided by urban green infrastructure. The present article provides a systematic search and synthesis of the most important literature to review indicators of urban green infrastructure. The main goal is to give an insight of how urban green infrastructure is measured in practice. Results show the set of ecosystem services that are being considered when assessing sustainability of green infrastructure and identify the most recurrent indicators at the different scales. This work is expected to contribute to the improvement of the evaluation of green infrastructure effectiveness for providing benefits for urban dwellers.This work was supported by the European Union’s Horizon 2020 research and innovation programme under the project Green Cities For Climate and Water Resilience, Sustainable Economic Growth, Healthy Citizens and Environments with reference 730283.Tudorie, CM.; Gielen, E.; Vallés-Planells, M.; Galiana, F.

    SELF BROADENING COEFFICIENTS AND IMPROVED LINE INTENSITIES FOR THE v7 BAND OF C2H4 NEAR 10.5 µm, AND IMPACT ON ETHYLENE RETRIEVALS FROM JUNGFRAUJOCH SOLAR SPECTRA

    Full text link
    Relying on high-resolution Fourier transform infrared (FTIR) spectra, the present work involved extensive measurements of individual line intensities and self-broadening coefficients for the ν7 band of 12C2H4. The measured self-broadening coefficients exhibit a dependence on both J and Ka. Compared to the corresponding information available in the latest edition of the HITRAN spectroscopic database, the measured line intensities were found to be higher by about 10 % for high J lines in the P branch and lower by about 5 % for high J lines of the R branch, varying between these two limits roughly linearly with the line positions. The impact of the presently measured line intensities on retrievals of atmospheric ethylene in the 949.0–952.0cm 1 microwindow was evaluated using a subset of ground-based high-resolution FTIR solar spectra recorded at the Jungfraujoch station. The use of HITRAN 2012 with line intensities modified to match the present measurements led to a systematic reduction of the measured total columns of ethylene by -4.1 +/- 0.1 %

    Towards a Greener University: Perceptions of Landscape Services in Campus Open Space

    Full text link
    [EN] Universities are showing a growing interest in becoming green institutions and improving campus open space management. Well-designed urban landscapes guided by green criteria integrate eco-friendly infrastructure which may be effective in facing urban challenges in the context of climate change. Student preferences and uses of campus outdoor environment should draw the attention of campus landscape planners. This study aims to analyse how the university community perceives landscape services provided by the Spanish Universitat Politecnica de Valencia's campus open space. An online questionnaire was sent to the university community to check its opinions, level of satisfaction, and their demands related to the current situation of the outdoor areas. Campus open spaces with different urban green infrastructure have a high potential to provide cultural, provisioning, and regulation landscape services. Respondents perceive the main benefits provided by campus open spaces to be that they are a place to relax, meet friends, and pass through. Their needs related to the welfare of outdoor areas and their preferences differ according to age, occupation, and time spent at the campus. This paper intends to help the university to meet environmental guidelines and to help other universities in their endeavour to reach sustainability and ensure the university community's well-being.This research was funded by European Commission, European Union's Horizon 2020, Green Cities for Climate and Water Resilience, Sustainable Economic Growth, Healthy Citizens and Environments; grant number 730283.Tudorie, CA.; Vallés-Planells, M.; Gielen, E.; Arroyo-López, MR.; Galiana, F.

    [ES] Hoy en día, resulta imposible enseñar y educar como antaño a una nueva generación de estudiantes que vive conectada a la tecnología. Una visión moderna del aprendizaje requiere la adaptación de estrategias y métodos clásicos de enseñanza. Este estudio propone la introducción de una aplicación móvil lúdica como recurso tecnológico de apoyo al aprendizaje, que fomente la educación y la conciencia ambiental en los estudiantes del Campus de Vera de la Universitat Politècnica de València. La aplicación Grow Green es una herramienta innovadora, que tiene el potencial de conseguir objetivos educativos y de sostenibilidad, más allá del mero entretenimiento. Este proyecto de gamificación desea ayudar a los estudiantes a conocer elementos de la biodiversidad local mediante diferentes rutas de flora (árboles y arbustos) y fauna (aves) urbana, experimentar la movilidad sostenible, disfrutar de los beneficios suministrados por elementos de infraestructura verde y descubrir estrategias verdes para la resiliencia urbana. El compromiso ambiental es otro contexto prometedor para la gamificación, facilitando la participación de la comunidad universitaria en censos de aves. La implantación de la aplicación Grow Green fomentará la adquisición de competencias específicas y transversales, que proporcionan un valor añadido a los estudiantes y otorgan un mayor atractivo al currículo docente.[EN] Nowadays, it is impossible to teach and educate a new generation of students who lives connected to technology in the same way it was done before.

    Raman and infrared spectra of dimethyl ether 13C-isotopologue (CH3O13CH3) from a CCSD(T) potential energy surface

    So far, no experimental data of the infrared and Raman spectra of 13C isotopologue of dimethyl ether are available. With the aim of providing some clues of its low-lying vibrational bands and with the hope of contributing in a next spectral analysis, a number of vibrational transition frequencies below 300 cm−1 of the infrared spectrum and around 400 cm−1 of the Raman spectrum have been predicted and their assignments were proposed. Calculations were carried out through an ab initio three dimensional potential energy surface based on a previously reported one for the most abundant dimethyl ether isotopologue (M. Villa et al., J. Phys. Chem. A 115 (2011) 13573). The potential function was vibrationally corrected and computed with a highly correlated CCSD(T) method involving the COC bending angle and the two large amplitude CH3 internal rotation degrees of freedom. Also, the Hamiltonian parameters could represent a support for the spectral characterization of this species. Although the computed vibrational term values are expected to be very accurate, an empirical adjustment of the Hamiltonian has been performed with the purpose of anticipating some workable corrections to any possible divergence of the vibrational frequencies. Also, the symmetry breaking derived from the isotopic substitution of 13C in the dimethyl ether was taken into account when the symmetrization procedure was applied
