IMAGE-BASED MODELING TECHNIQUES FOR ARCHITECTURAL HERITAGE 3D DIGITALIZATION: LIMITS AND POTENTIALITIES
2013
Abstract. 3D reconstruction from images has undergone a revolution in the last few years. Computer vision techniques use photographs from data set collection to rapidly build detailed 3D models. The simultaneous applications of different algorithms (MVS), the different techniques of image matching, feature extracting and mesh optimization are inside an active field of research in computer vision. The results are promising: the obtained models are beginning to challenge the precision of laser-based reconstructions. Among all the possibilities we can mainly distinguish desktop and web-based packages. Those last ones offer the opportunity to exploit the power of cloud computing in order to car…
The Form is Not a Proper Part in Aristotle’s Metaphysics Z.17, 1041b11–33
2018
When Aristotle argues at the 'Metaphysics' Z.17, 1041b11–33 that a whole, which is not a heap, contains ‘something else’, i.e. the form, besides the elements, it is not clear whether or not the form is a proper part of the whole. I defend the claim that the form is not a proper part within the context of the relevant passage, since the whole is divided into elements, not into elements and the form. Different divisions determine different senses of ‘part’, and thus the form is not a part in the same sense as the elements are parts. I object to Koslicki’s (2006) interpretation, according to which the form is a proper part along the elements in a single sense of ‘part’, although she insists th…
A2Ba: Adaptive Background Modelling for Visual Aerial Surveillance Conditions
2015
International audience; Background modelling algorithms are widely used to define a part of an image that most time remains stationary in a video. In surveillance tasks, this model helps to recognize those outlier objects in an area under monitoring. Set up a background model on mobile platforms (UAVs, intelligent cars, etc.) is a challenging task due camera motion when images are acquired. In this paper, we propose A2Ba, a robust method to support instabilities caused by aerial images fusing different information about image motion. We used frame difference as first approximation, then age of pixels is estimated. This latter gives us an invariability level of a pixel over time. Gradient di…
Problemy współczesnej genologii medialnej
2020
The paper is an attempt at clarifying the object of research into media genology, distancing itself from literary studies genology. In the era of convergence of mass media, we can observe a progress in the blurring of the border between information and journalism, which consequently changes the contemporary communicative convention. As a result, information services are often degraded and the sense of implementing ‘traditional’ indicators of mass media genres is questioned. The change of communicative convention in contemporary mass media requires, above all, the use of cultural context for its analysis, as it determines the methods of creating messages and means of receiving them. It also …
Shoreline Extraction and Change Detection using 1:5000 Scale Orthophoto Maps: A Case Study of Latvia-Riga
2015
Coastal management requires rapid, up-to-date, and
 correct information. Thus, the determination of coastal movements and its
 directions has primary importance for coastal managers. For monitoring the
 change of shorelines, remote sensing data, very high resolution aerial images
 and orthophoto maps are utilized for detections of change on shorelines. It is
 possible to monitor coastal changes by extracting the coastline from orthophoto
 maps. Along the Baltic Sea and Riga Gulf, Latvian coastline length is 496 km.
 It is rich of coastal resources and natural biodiversity.  Around 120 km of coastline are affected by
 significant coastal chang…
La neologia: un nou camp a la cerca de la seva consolidació científica
2015
En aquest text s’ofereix una panoràmica àmplia de la neologia com a camp de coneixement i com a camp de treball. Així mateix s’exploren les relacions que la neologia manté amb altres matèries com la psicologia i la sociologia, i les seves connexions amb les tecnologies. Els neologismes són l’objecte central de la neologia com a camp de coneixement. L’article mostra la dificultat de delimitar clarament aquest objecte per tal com es tracta d’un objecte relatiu, a més de polièdric. La relativitat dels neologismes obliga a definir-los sobre la base d’establir un punt de referència a partir del qual una unitat és neològica en funció de la producció, de la recepció o de la circulació social. L’ar…
Device-Based Measures of Sedentary Time and Physical Activity Are Associated With Physical Fitness and Body Fat Content
2020
Introduction/Purpose: Physical activity and sedentary time may associate with physical fitness and body composition. Yet, there exists some observational studies that have investigated the associations of device-based measures of sedentary time and physical activity (PA) with cardiorespiratory fitness (CRF) and body composition but associations with muscular fitness (MF) are less studied.Methods: Objective sedentary time and physical activity was measured by a hip worn accelerometer from 415 young adult men (age: mean 26, standard deviation 7 years). Cardiorespiratory fitness (VO2max) (CRF) was determined using a graded cycle ergometer test until exhaustion. Maximal force of lower extremiti…
Valutare: perchè e come

After OM 172/20, the attention of researchers was focused on the new way of evaluating learning objectives in primary school. It is also necessary to evaluate the degree of overall development of the pupils in view of the certification of skills.
Situazioni didattiche per pensare e ripensare criticamente la conoscenza
2022
Un obiettivo fondamentale da considerare a scuola come all’università è l’esercizio della capacità critica. Le abilità di pensiero critico sono sempre più necessarie per insegnare ai giovani a comprendere, a pensare meglio usando strategie di controllo ed autoanalisi della conoscenza. Il pensiero critico è importante nei contesti sociali e interpersonali in cui devono essere assunte scelte adeguate, autonome e indipendenti. Leggere e scrivere sono strumenti che aiutano gli studenti a ripensare e chiarire, discernere e valutare, interpretare significati in rapido cambiamento. Dopo una breve rassegna di studi, sono approfonditi gli obiettivi e le azioni per potenziare il pensiero critico negl…
3–10-vuotiaiden lasten motoriset perustaidot
2016
Motoriset perustaidot ja niiden kehittyminen luovat perustan lapsen liikkumiselle ja kokonaisvaltaiselle fyysiselle aktiivisuudelle. Perustaidot tulisi oppia hallitsemaan ennen kouluikää. Lapsuuden aikaiset hyvät motoriset taidot ennustavat runsaampaa fyysistä aktiivisuutta myös myöhemmin nuoruusvuosina. Motorisilla taidoilla on lisäksi yhteyksiä lapsen kognitiivisiin taitoihin, terveystekijöihin sekä psykologista hyvinvointia kuvaaviin muuttujiin. Toistaiseksi Suomesta puuttuvat lasten motorisia taitoja mittaavat laajat kartoitukset, jonka vuoksi tämän tutkimuksen tarkoituksena oli kuvata, minkä- laiset ovat 3–10-vuotiaiden tyttöjen ja poikien motoriset perustaidot vuonna 2015. Tutkimuksee…
