La città che comunica
2005
Corporate image is a crucial aspect of public utility communications. Strictly speaking, it involves the image (or identity) of a company insofar as the English word, corporation, corresponds to “company” in Italian. However, in general, its semantic meaning can be used for different agencies, political parties, town councils or cultural assets. Since this issue of the magazine focuses entirely on public utility communications, we can further discuss the meaning of corporate image by considering the Irish town of Cork – the 2005 European Capital of the Culture – as an agency that promotes its cultural identity by using a series of communication strategies.
Conformation constraints for efficient viscoelastic fluid simulation
2017
The simulation of high viscoelasticity poses important computational challenges. One is the difficulty to robustly measure strain and its derivatives in a medium without permanent structure. Another is the high stiffness of the governing differential equations. Solutions that tackle these challenges exist, but they are computationally slow. We propose a constraint-based model of viscoelasticity that enables efficient simulation of highly viscous and viscoelastic phenomena. Our model reformulates, in a constraint-based fashion, a constitutive model of viscoelasticity for polymeric fluids, which defines simple governing equations for a conformation tensor. The model can represent a diverse pa…
Aperiodic Diffract: Study of diffraction gratings
2014
In this work we introduce a virtual laboratory, APERIODIC DIFFRACT, developed in Matlab GUI (Graphical User Interface) as an informatics tool for teaching the diffractive properties of aperiodic gratings. This GUI allows the student to generate aperiodic sequences by iterating and lets to study the spectra for different iterating orders.<br /><br />
Pharmacological distribution diagrams: a tool for de novo drug design.
1996
Abstract Discriminant analysis applied to SAR studies using topological descriptors allows us to plot frequency distribution diagrams: a function of the number of drugs within an interval of values of discriminant function vs. these values. We make use of these representations, pharmacological distribution diagrams (PDDs), in structurally heterogeneous groups where generally they adopt skewed Gaussian shapes or present several maxima. The maxima afford intervals of discrimianant function in which exists a good expectancy to find new active drugs. A set of β-blockers with contrasted activity has been selected to test the ability of PDDs as a visualizing technique, for the identification of n…
Programming languages for data-Intensive HPC applications: A systematic mapping study
2020
This work is a result of activities from COST Action 10406 High -Performance Modelling and Simulation for Big Data Applications (cHiPSet), funded by the European Cooperation in Science and Technology. FCT, Portugal for grants: NOVA LINCS Research Laboratory Ref. UID/ CEC/ 04516/ 2019); INESC-ID Ref. UID/CEC/50021/2019; BioISI Ref. UID/MULTI/04046/2103; LASIGE Research Unit Ref. UID/CEC/00408/ 2019. A major challenge in modelling and simulation is the need to combine expertise in both software technologies and a given scientific domain. When High-Performance Computing (HPC) is required to solve a scientific problem, software development becomes a problematic issue. Considering the complexity…
Cue combination in a combined feature contrast detection and figure identification task
2006
AbstractTarget figures defined by feature contrast in spatial frequency, orientation or both cues had to be detected in Gabor random fields and their shape had to be identified in a dual task paradigm. Performance improved with increasing feature contrast and was strongly correlated among both tasks. Subjects performed significantly better with combined cues than with single cues. The improvement due to cue summation was stronger than predicted by the assumption of independent feature specific mechanisms, and increased with the performance level achieved with single cues until it was limited by ceiling effects. Further, cue summation was also strongly correlated among tasks: when there was …
Assessing forest landscape structure using geographic windows.
2001
Landscape structure, interpreted as indicator of functional processes, has become a main attribute of multiresource forest inventories, enhancing its value with respect to society needs. This approach implies effective use of earth observation techniques and geographic information systems to obtain a global view of the inventoried landscapes and to understand the ecological functions of large spatially-heterogeneous landscape mosaics. Landscape structure often reveal extremely complex patterns that can only be very roughly characterized by methods of Euclidean geometry. Conversely, fractals can be applied to adequately describe many of the irregular, fragmented patterns found in nature. In …
Diseño gráfico para formar al profesorado de primaria
2021
Educar en diseño es probablemente la base para una predisposición social hacia la creatividad y la innovación. Presentamos los resultados de una investigación desarrollada en la práctica universitaria, formulada metodológicamente como estudio de caso. Incorporamos la práctica del diseño gráfico al currículum formativo de Maestro/a en Educación Primaria. Si queremos que la ciudadanía aprecie el diseño, conviene preparar al profesorado. Para lograr este acercamiento al diseño gráfico planteamos un taller en el que cada participante elabora su propio exlibris. Los resultados positivos nos animan a continuar con este tipo de iniciativas que aglutinan diseño, patrimonio, identidad e inclusión. E…
Basic variables in reflection-impulsivity: A training programme to increase reflectivity
1993
We found that reflective children in our study had better academic qualifications than impulsive ones. We worked with a sample of 201 Spanish children in their last year of Primary School. We elaborated and applied an intervention programme to increase reflectivity. The results were excellent and showed consistency and stability, which is very unusual in the context of R-I research. There was no significant difference between boys and girls’ performance on MFF20. The children were 12, 13 and 14 year olds and we found a reflection increase at 13 but not at 14. Contrary to the opinion of Salkind and Nelson on this point concerning MFFT, we believe that MFF20 is adequate for these ages. The Sp…
