Characterisation of component pigments in a mixture
2011
This work is part of Raman spectra database constitution of pigments and materials of Cultural Heritage interest for polychrome artworks characterization. The colours of paintings are often obtained mixing pigments of palette artist’s. The attribution of a work of art to an author and the individuation of fakes are related to the identification of used pigments and also to the detection of mixture constituents. The main research objective is the extension of PH3DRA laboratory database with information useful to detect not only each single pigment but also quantitative data regarding its relative ratio in the examined mixture. The availability of spectra as revealed represents the primary li…
A Velocity Estimation Technique for a Monocular Camera Using mmWave FMCW Radars
2021
Perception in terms of object detection, classification, and dynamic estimation (position and velocity) are fundamental functionalities that autonomous agents (unmanned ground vehicles, unmanned aerial vehicles, or robots) have to navigate safely and autonomously. To date, various sensors have been used individually or in combination to achieve this goal. In this paper, we present a novel method for leveraging millimeter wave radar’s (mmW radar’s) ability to accurately measure position and velocity in order to improve and optimize velocity estimation using a monocular camera (using optical flow) and machine learning techniques. The proposed method eliminates ambiguity in optical flow veloci…
Advances in mobile financial services: a review of the literature and future research directions
2022
PurposeUsing the theory, construct, method, moderator (TCMM) format, this framework-based review critically analyses the mobile financial services (MFSs) field through a detailed synthesis and analysis of a sample of mainstream empirical research published in various scientific journals within the period 2009–2020.Design/methodology/approachThe authors followed a three-step structured approach suggested by Webster and Watson (2002) to search for the literature to synthesise the global perspectives on MFSs and their associated applications and systems. The literature research resulted in the identification of 115 most relevant articles.FindingsThe authors identified three major categories or…
Digitālo rīku efektivitāte personīgo finanšu pārvaldīšanā
2018
Bakalaura darbā “Digitālo rīku efektivitāte personīgo finanšu pārvaldīšanā” pētīta digitālo rīku izmantošanas efektivitāte personīgo finanšu pārvaldīšanā un studentu finanšpratības līmenis. Pētījuma mērķis ir noteikt, vai digitālie rīki var kalpot par efektīvu instrumentu, ar kuru palīdzību iespējams īstenot personīgo finanšu pārvaldīšanas procesu. Lai sasniegtu izvirzīto mērķi, bakalaura darbā izmantotas kvantitatīvas un kvalitatīvas pētniecības metodes – anketēšana, daļēji strukturētā intervija, dienasgrāmatas metode un kvalitatīvā kontentanalīze. Iegūtie dati analizēti un interpretēti, balstoties uz pragmatisma metateoriju un teorētisko modeli ELIS. Rezultāti parāda, ka digitālie rīki sn…
Edu-social Algorithm: educare con i social network a scuola. Un modello operativo per il Mobile Learning
2023
In questo lavoro si mostreranno i presupposti teorici e operativi per lo sviluppo di un Mobile Learning capace di coniugare didattica in presenza ed esperienze digitali, sfruttando Instagram come social media privilegiato per una proposta di un modello metodologico volto a strumentalizzare le funzioni multimediali e interattive interne all’applicazione. I risultati qualitativi del progetto di ricerca-azione Edu-social Algorithm mostrano una serie di contenuti mediaeducativi che evidenziano il potenziale pedagogico dentro il social media Instagram e la replicabilità del modello metodologico sviluppato.
Orientation Aids for Mobile Maps
2015
Using mobile maps to represent urban, work, or entertainment environments offers new possibilities to plan and carry out tasks. One potentially critical problem in mobile map usage is the misalignment between the user's frame of reference and the frame of reference of the map. In the experiment reported here, three different ‘orientation aids’ were tested in the context of restricted space, such as a large factory hall. The aim of the study was to find out how user interface design can help the user mentally align misaligned frames of reference for efficient mobile map use. The results of the experiment (N = 12) suggest using a ‘you are here’ marker and landmark highlighting, while canonica…
Digitālās paaudzes uzvedība tiešsaistē: mobilā sociālā tīkla „Instagram” lietotāju (21-26 gadu vecumā) analīze
2017
Maģistra darba mērķis ir izpētīt digitālās paaudzes uzvedību sociālajā tiklā „Instagram”, kā arī noteikt faktorus, kas ietekmē viņu attieksmi un uzvedību šajā sociālajā platformā, raksturot mobilo sociālo tīklu. Darbā ir aplūkoti digitālās paaudzes raksturojumi, cilvēku uzvedība tiešsaistē, sociālie tīkli, kā arī mobilā kultūra un vizuālā komunikācija, un „Instagram” vietne. Tika izmantotas kvalitatīvas un kvantitatīvas metodes: kontentanalīze, dienasgrāmatas, daļēji strukturētas intervijas un aptauja. Kā galveno secinājumu var minēt to, ka „Instagram” vietnē jaunieši jūtās brīvāk un radošāk. Labdabīgā atmosfēra, satura dažādība un draudzīgā auditorija ir svarīgākie aspekti, kas raksturo tī…

On the Fundamental Period of Infilled RC Buildings
2015
This paper investigates the fundamental period of vibration of RC buildings by means of finite element macro-modelling and modal eigenvalue analysis. As a base study, a number of 14-storey RC buildings have been considered \"according to code designed\" and \"according to code non-designed\". Several parameters have been studied including the number of spans; the span length in the direction of motion; the stiffness of the infills; the percentage openings of the infills and; the location of the soft storeys. The computed values of the fundamental period are compared against those obtained from seismic code and equations proposed by various researchers in the literature. From the analysis of…
Modelización de riesgos climáticos y sistemas de vigilancia y alerta en la Comunitat Valenciana
2013
El primer objetivo de esta Tesis está relacionado con el desarrollo e implementación de diferentes sistemas de vigilancia y alerta para el territorio de la Comunitat Valenciana: un sistema de predicción meteorológica en tiempo real basado en el modelo atmosférico de mesoescala Regional Atmospheric Modeling System (RAMS) y un sistema de previsión del Índice UV (UVI), basado en el modelo Santa Barbara DISORT Atmospheric Radiative Transfer (SBDART). Además, se propone una metodología que proporciona un entorno computacional adecuado para la administración y coordinación de los diferentes procesos implicados en ambos sistemas de vigilancia. La principal mejora de la predicción UVI es la utiliza…
