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…
Security in Modern Smart Cities: An Information Technology Perspective
2019
In a big and modern city, the security system is not a single-layered single module system. Instead, it consists of many layers with autonomous subsystems which are capable of interfacing reciprocally in an efficient and coordinated way horizontally and vertically. The design of such indigenous subsystems and ensuring tight interaction between them while taking into account high usability and resource utilization is not a simple task. In this regard, this article provides a comprehensive overview of the security systems in smart cities. We begin by introducing trends and key stakeholders in smart cities. Next, we provide examples of mass surveillance systems in developed countries like the …
Datos personales y Cloud Computing
2016
Póster presentado en el XV Workshop de Rebiun "Datos y Bibliotecas", celebrado en Castellón los días 29 y 30 de septiembre de 2016 Las bibliotecas Universitarias están recurriendo con más frecuencia a soluciones informáticas en la nube para seguir ofreciendo el mejor servicio a sus usuarios y, de paso, aprovecharse del ahorro en costes, escalabilidad y mejoras en la gestión de datos que ello supone. Estos servicios en la nube los suelen ofrecer grandes empresas internacionales que han construido complejas y robustas infraestructuras, muchas veces localizadas fuera del territorio de la UE, para ayudar a las bibliotecas a seleccionar, adquirir, procesar, conservar y difundir sus recursos. Per…
Multi-objective Optimization for Computation Offloading in Fog Computing
2018
Fog computing system is an emergent architecture for providing computing, storage, control, and networking capabilities for realizing Internet of Things. In the fog computing system, the mobile devices (MDs) can offload its data or computational expensive tasks to the fog node within its proximity, instead of distant cloud. Although offloading can reduce energy consumption at the MDs, it may also incur a larger execution delay including transmission time between the MDs and the fog/cloud servers, and waiting and execution time at the servers. Therefore, how to balance the energy consumption and delay performance is of research importance. Moreover, based on the energy consumption and delay,…
Pilvipalveluiden käyttö
2017
Tämä tutkielma perehtyy pilvipalveluihin, niiden käyttäjäryhmiin sekä syihin, miksi pilvipalveluita käytetään. Pilvipalvelut ovat internetin yli tarjottavia laitteita ja ohjelmistoja, joihin on samanaikainen pääsy eri puolilta maailmaa. Kaikilla on mahdollisuus hyödyntää pilvipalveluiden tuomia etuja niin teknisesti kuin taloudellisestikin. Mobiililaitteiden ja langattoman nettiyhteyden lisääntyvän suosion sekä koko ajan kasvavan datamäärän myötä myös pilvipalveluiden käyttö on laajentunut viime vuosina paljon. Pilvipalvelut tuovat paljon hyötyjä, jotka houkuttelevat lisää käyttäjiä. Toisaalta pilvipalveluiden varjopuolena on turvallisuus, joka mietityttää monia käyttäjiä. The usage of clou…
Efficacy of the cloud computing technology in the management of communications and business processes of the companies
2016
W artykule zbadano tendencje rozwoju i stosowania różnych klas systemów informatycznych w zarządzaniu w relacji do rodzajów procesów biznesowych. Zaprezentowano krótki przegląd aktualnego stanu wykorzystania technologii chmury obliczeniowej na świecie i na Ukrainie. Korzyści wynikające z zastosowania modelu "SaaS - Software as a Service" zostały wyjaśnione na przykładzie innowacji międzynarodowego projektu "Bitrix 24", w którym zrealizowane zostały główne cele systemów CRM w połączeniu z szerokimi możliwościami koordynacji procesów komunikacyjnych i biznesowych nowoczesnych firm. Projekt ten został przetłumaczony na większość języków europejskich i wykorzystuje narzędzia społecznego środowi…
Supporting Cyber Resilience with Semantic Wiki
2016
Cyber resilient organizations, their functions and computing infrastructures, should be tolerant towards rapid and unexpected changes in the environment. Information security is an organization-wide common mission; whose success strongly depends on efficient knowledge sharing. For this purpose, semantic wikis have proved their strength as a flexible collaboration and knowledge sharing platforms. However, there has not been notable academic research on how semantic wikis could be used as information security management platform in organizations for improved cyber resilience. In this paper, we propose to use semantic wiki as an agile information security management platform. More precisely, t…
