Crear y gestionar conocimiento en red: agentes y procesos implicados.

2013

El proposito de este articulo es delimitar las funciones y roles de los principales agentes y los procesos que intervienen en la creacion y gestion del conocimiento (CGC) en red desde una plataforma virtual. Recoge, al respecto, algunos de los resultados mas destacados que se derivan de la investigacion “Agentes y procesos en la gestion del conocimiento en red” (I+D+i). El proceso de investigacion seguido ha supuesto, fundamentalmente, la puesta en marcha de 5 redes de CGC desde una plataforma virtual (Moodle) sostenida en el debate como estrategia; tambien la realizacion de un trabajo de campo que considero un cuestionario de autodiagnostico para 15 directivos y especialistas en desarrollo…

Pseudo-haptic Controls for Mid-air Finger-based Menu Interaction

2019

Virtual Reality (VR) is more accessible than ever these days. While topics like performance, motion sickness and presence are well investigated, basic topics as VR User Interfaces (UIs) for menu control are lagging far behind. A major issue is the absence of haptic feedback and naturalness, especially when considering mid-air finger-based interaction in VR, when "grabbable" controllers are not available. In this work, we present and compare the following two visual approaches to mid-air finger-based menu control in VR environments: a planar UI similar to common 2D desktop UIs, and a pseudo-haptic UI based on physical metaphors. The results show that the pseudo-haptic UI performs better in t…

A VR-Enhanced Rollover Car Simulator and Edutainment Application for Increasing Seat Belt Use Awareness

2021

Most countries have active road safety policies that seek the objective of reducing deaths in traffic accidents. One of the main factors in this regard is the awareness of the safety measures, one of the most important being the correct usage of the seat belt, a device that is known to save thousands of lives every year. The presented work shows a VR-enhanced edutainment application designed to increase awareness on the use of seat belts. For this goal, a motorized rollover system was developed that, synchronized with a VR application (shown in a head-mounted display for each user inside a real car), rolls over this car with up to four passengers inside. This way, users feel the sensations …

Self-dressing in classical and quantum electrodynamics

2003

A short review is presented of the theory of dressed states in nonrelativistic QED, encompassing fully and partially dressed states in atomic physics. This leads to the concept of the reconstruction of the cloud of virtual photons and of self-dressing. Finally some recent results on the classical counterpart of self-dressing are discussed and a comparison is made with the QED case. Attention is drawn to open problems and future lines of research are briefly outlined.

Achieving Intelligent Traffic-aware Consolidation of Virtual Machines in a Data Center Using Learning Automata

2016

Cloud Computing (CC) is becoming increasingly pertinent and popular. A natural consequence of this is that many modern-day data centers experience very high internal traffic within the data centers themselves. The VMs with high mutual traffic often end up being far apart in the data center network, forcing them to communicate over unnecessarily long distances. The consequent traffic bottlenecks negatively affect both the performance of the application and the network in its entirety, posing nontrivial challenges for the administrators of these cloudbased data centers. The problem can, quite naturally, be compartmentalized into two phases which follow each other. First of all, the VMs are co…

Architettura altomedievale nel Santuario di San Michele: analisi stratigrafica degli elevati e studio ricostruttivo 3D

2012

Il Santuario di San Michele a Monte Sant’Angelo (FG) costituisce uno dei più importanti e antichi luoghi della cristianità occidentale. La sede del culto riservato all’Angelo è posta all’interno di una Caverna situata a metà del fianco settentrionale del rilievo montuoso sul cui pianoro si estende il centro abitato. Il contributo riguarda lo studio architettonico, dal rilievo alla lettura stratigrafica muraria fino alla ricostruzione virtuale, del monumento di età longobarda The Sanctuary of San Michele in Monte Sant’Angelo (FG) is one of the most important and ancient places of Western Christianity. The seat of the cult reserved for the Angel is placed inside a Cave located in the middle o…

I Telamoni del Tempio di Zeus ad Agrigento: rilievi, disegni e ricostruzioni

2013

Oggetto dello studio qui presentato è la ricostruzione di un intercolumnio del fronte esterno del Tempio di Zeus ad Agrigento, basata sul rilievo del Telamone oggi custodito presso il Museo Archeologico, sugli studi e i numerosi saggi di ricostruzione proposti dagli studiosi dal XVIII secolo fino alla metà dello scorso secolo e sulla analisi strutturale del Telamone ricostruito nel Museo. The drawings of the telamones, the giant statues placed the front of the Temple of Zeus in the archaeological area of Agrigento, have fascinated some of the most famous neoclassical architects in Europe. The virtual reconstruction of one intercolumnial of the Temple, based both on the range-based survey of…

A tool in support of oral implantology

2009

Il brevetto si riferisce ad un dispositivo che trova applicazione nella tecnica “flap-less” in chirurgia impiantare (inserimento di impianti senza esecuzione di lembo chirurgico), tecnica meno invasiva e traumatica per il paziente; esso consente di: - eseguire in modo diretto e preciso la rilevazione del profilo osseo esterno del sito impiantare - determinare l’angolazione ottimale dell’asse di foratura - guidare l’operazione di fresatura secondo l’asse prescelto Il dispositivo, grazie alla sua adattabilità e modularità è utilizzabile per eseguire siti implantari sia singoli che multipli ed è adattabile a tutte le variabili anatomiche che si possono presentare, è inoltre sterilizzabile e qu…

Viajes de cine. El relato del turismo en el cine hispánico

2017

Entre las estrategias desarrolladas por la industria turística para captar la atención del público viajero hacia destinos concretos una de las más rentables consiste en convertirlos en escenarios de las tramas fílmicas. Como envoltorio de los relatos cinematográficos, dichos escenarios quedan grabados en el imaginario colectivo, que los transforma en objetos de deseo susceptibles de ser visitados más tarde o más temprano. El análisis de esa exhibición cinematográfica de los espacios autóctonos es el objeto de los trabajos contenidos en el libro. Mediante el estudio de películas concretas, los autores abordan asimismo otros aspectos que muestran cómo el cine hispánico se hace eco de las tran…
