Visualizations for Decision Support in Scenario-based Multiobjective Optimization
2021
Reproducibility artifacts for: Babooshka Shavazipour, Manuel López-Ibáñez, and Kaisa Miettinen. Visualizations for Decision Support in Scenario-based Multiobjective Optimization. Information Sciences, 2021. doi:10.1016/j.ins.2021.07.025. Abstract: We address challenges of decision problems when managers need to optimize several conflicting objectives simultaneously under uncertainty. We propose visualization tools to support the solution of such scenario-based multiobjective optimization problems. Suitable graphical visualizations are necessary to support managers in understanding, evaluating, and comparing the performances of management decisions according to all objec…
Sistemi integrati per la visualizzazione immersiva
2015
Il disegno dell’architettura ha, tra i suoi obiettivi disciplinari, quello di “far vedere” lo spazio, sia nelle sue declinazioni temporali, sia in quelle descrittive di forme, luce, colori e materiali, caratteri connotativi che cerca di riprodurre grazie a metodi di proiezione codificati e tecniche di rappresentazione in continuo mutamento. Tra le tecniche di rappresentazione informatica la visualizzazione immersiva consente di ruotare lo sguardo, in tempo reale, all’interno di uno spazio, cercando di superare i limiti della rappresentazione piana, simulando la visione sferica dello spazio. La tecnica può essere utilizzata sia per vedere la realtà esistente, tramite immagini fotografiche, s…
Masked priming effects are modulated by expertise in the script.
2010
In a recent study using a masked priming same–different matching task, García-Orza, Perea, and Muñoz (2010) found a transposition priming effect for letter strings, digit strings, and symbol strings, but not for strings of pseudoletters (i.e., [Formula: see text] produced similar response times to the control pair [Formula: see text]). They argued that the mechanism responsible for position coding in masked priming is not operative with those “objects” whose identity cannot be attained rapidly. To assess this hypothesis, Experiment 1 examined masked priming effects in Arabic for native speakers of Arabic, whereas participants in Experiments 2 and 3 were lower intermediate learners of Arabi…
Are transposition effects specific to letters?
2010
Recent research has consistently shown that pseudowords created by transposing two letters are perceptually similar to their corresponding base words (e.g., jugde–judge). In the framework of the overlap model (Gomez, Ratcliff, & Perea, 2008), this effect is due to a noisy process in the localization of the “objects” (e.g., letters, kana syllables). In the present study, we examine whether this effect is specific to letter strings or whether it also occurs with other “objects” (namely, digits, symbols, and pseudoletters). To that end, we conducted a series of five masked priming experiments using the same–different task. Results showed robust effects of transposition for all objects, ex…
La promoción de la imagen política en Instagram: un estudio del perfil personal de Santiago Abascal (Vox) en 2018
2020
Due to Instagram’s growing popularity in Spain, politicians have also begun to turn to this social network increasingly more. Accordingly, this paper analyses the visual and textual discourse of 259 posts published throughout 2018 on the personal Instagram profile of Santiago Abascal, the leader of the party Vox. Insofar as he is the Spanish politician with the highest number of followers on Instagram, the aim here is to analyse how he uses this social network in order to identify possible strategies that justify his growing number of followers. In the analysis, special attention was paid to aspects that might have contributed to the (self)presentation of Abascal and the promotion of his pa…
Definition of a Workflow for Web Browsing of 3D Models in Archaeology
2016
The Cultural Heritage (CH) is a fundamental element of promotion of territories and of tourism development. Publishing 3D models of archaeological sites and their three-dimensional reconstruction on the Web is one of the best ways to spread their knowledge. However, many recent scientific researches in this field have highlighted the limitations and difficulties related to the networking of interactive 3D models. The main difficulties are related to the complexity and the size of models, which influence the access speed, and the cost of software and hardware needed for the publication on the WEB. In light of this background, this article describes the further advances of research activities…
Characterization of the human visual system threshold performance by a weighting function in the Gabor domain
1997
Abstract As evidenced by many physiological and psychophysical reports, the receptive fields of the first-stage set of mechanisms of the visual process fit to two-dimensional (2D) compactly supported harmonic functions. The application of this set of band-pass filter functions to the input signal implies that the visual system carries out some kind of conjoint space/spatial frequency transform. Assuming that a conjoint transform is carried out, we present in this paper a new characterization of the visual system performance by means of a weighting function in the conjoint domain. We have called this weighting function (in the particular case of the Gabor transform) the Gabor stimuli Sensiti…
N-Daļiņu Simulācija
2015
Elvja Egles kvalifikācijas darbā „N-Daļiņu Simulācija” tika izstrādāta simulācijas programma, kura attēlo lādētu daļiņu kustības savā starpā. Tika izmantota OpenGL bibliotēka, lai varētu izveidot daļiņu attēlojumu 3-D simulācijā. OpenGL piedāvāja vairākus veidus, kā daļiņas tiek uzzīmētas un kā tās tiek apgaismotas. Fizikas moduļi, sadursmes un animācija tika implementēta kopā ar OpenGL bibliotēku, lai lādēto daļiņu simulācija būtu pietiekami saprotama fizikas skolniekiem, kuri mācās par Kulona likumu. Visa programma tika izstrādāta caur Microsoft Visual Studio uz Windows vides.
A Framework for Opening Data and Creating Advanced Services in the Health and Social Fields
2016
Open data is publicly available data that can be universally and readily accessed, used, and redistributed. Open data holds particular potential in the health and social sectors but, presently, health and social data are often published in a ‘closed’ format.There are different tools that allow to ‘open’ data, clean, structure and process them in order to elaborate them and build advanced services but, unfortunately, there is no single tool that can be used to perform all different tasks. We believe that the availability of Open Data in the health and social fields should be greatly increased and a way for creating new health and social services should be provided. In this paper, we present …
