Leveraging Users' Likes in a Video Streaming P2P Platform
2014
This paper investigates how a p2p television platform can take advantage of the presence of frequent channel viewers to grant them a more satisfying service than to less regular spectators. The idea we explore is to learn beforehand about the users' interests, in order to cluster them in groups that display different behaviors; then, the neighborhood creation strategy and video chunk scheduling algorithm of the overlay is altered, with the aim of serving frequent spectators in a privileged manner, providing them with a faster access to the selected channel without overly penalizing less habitual customers. An analytical model is developed, to capture the difference in startup delay that the…
Odontogenic calcificant cystic tumor : a report of two clinical cases
2007
Odontogenic Calcificant Cystic Tumor (OCCT) is an infrequent injury. It arises from odontogenic epithelial rests present in the maxilla, jaw or gum. Gorlin and col. described the OCCT for first time as an own pathological entity in 1962. Clinically, the OCCT represents 1% of the odontogenic injuries. It is possible to be found from the first decade to the eighth decade. It affects in same proportion the maxilla and the jaw, being the most common in the dented zones, with greater incidence in the first molar area. Two case reports of OCCT in two different ages, both in female individuals, one at 5 years old and the other at 35 years old are presented. Enucleation of the tumor was the treatme…
Regular solutions for nonlinear elliptic equations, with convective terms, in Orlicz spaces
2022
We establish some existence and regularity results to the Dirichlet problem, for a class of quasilinear elliptic equations involving a partial differential operator, depending on the gradient of the solution. Our results are formulated in the Orlicz-Sobolev spaces and under general growth conditions on the convection term. The sub- and supersolutions method is a key tool in the proof of the existence results.
The Supranational Dimension in Max Weber’s Vision of Politics
2019
Max Weber analyzed politics from the perspective of Chancen for actors, and he never separated world politics from domestic politics. The “Westphalian balance” between great European powers shaped Weber’s views on international polity. However, he also regarded Western individualism, human rights, and parliamentary democracy as necessary qualities to possess in order to be recognized as a great power. This vision provided the basis for his wartime critique of the expansionist tendencies in German foreign policy and for his demand for the parliamentarization of German politics. After the end of World War I, Weber used Woodrow Wilson’s idea of the League of Nations as the basis for a proposal…
Crescere/Svilupparsi. Teorie e rappresentazioni fra mondo antico e scienze della vita contemporanee
2020
Il volume raccoglie i contributi scientifici di diversi autori, la maggior parte dei quali avevano presentato le loro relazioni già nell'ambito del Convegno di studi intitolato "Memoria scientiae 2019. Crescere/Svilupparsi" (Palermo, 21-23 febbraio 2019) sulle teorie e rappresentazioni della crescita umana e degli altri organismi viventi nel mondo antico (in particolare greco e romano) e nelle moderne scienze della vita. The volume collects the scientific contributions of various authors, most of whom had presented their reports already in the context of the study conference entitled "Memoria scientiae 2019. Grow / Develop" (Palermo, February 21-23, 2019) on theories and representations of …
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…
Teaching Knowledge Management by Combining Wikis and Screen Capture Videos
2011
PurposeThis paper aims to report on the design and creation of a knowledge management course aimed at facilitating student creation and use of social interactive learning tools for enhanced learning.Design/methodology/approachThe era of social media and web 2.0 has enabled a bottom‐up collaborative approach and new ways to publish work on the web, promoted by tools such as YouTube video service. In this spirit a knowledge management course was designed aiming to facilitate university students to compose videos on different difficult concepts in the theory part of the course by searching for explanations on the web and by creating a Windows Media Player video focusing on the self‐defined pro…
Dependency on un-captured GDP as a source of resilience beyond economic value in countries with advanced ICT infrastructure: Similarities and dispari…
2015
Abstract The majority of countries with advanced information and communication technology (ICT) infrastructure have been experiencing extended stagnation due to an “embedded” trap in ICT advancement. However, certain countries have been able to sustain a high level of ICT- driven global competitiveness. This suggests that in these contexts there is resilience beyond economic value. Finland and Singapore can be considered countries of resilience with respect to ICT-driven global competitiveness because of their continued GDP growth despite the recession. While both countries share significant similarities including institutional strength in ICT, they demonstrate noteworthy disparities in the…
A two-step, user-centered approach to personalized tourist recommendations
2017
Geo-localized, mobile applications can simplify a tourist visit, making the relevant Point of Interests more easily and promptly discernible to users. At the same time, such solutions must avoid creating unfitting or rigid user profiles that impoverish the users' options instead of refining them. Currently, user profiles in recommender systems rely on dimensions whose relevance to the user is more often presumed than empirically defined. To avoid this drawback, we build our recommendation system in a two-step process, where profile parameters are evaluated preliminarily and separately from the recommendations themselves. We describe this two-step evaluation process including an initial surv…
Convolutional neural networks in skin cancer detection using spatial and spectral domain
2019
Skin cancers are world wide deathly health problem, where significant life and cost savings could be achieved if detection of cancer can be done in early phase. Hypespectral imaging is prominent tool for non-invasive screening. In this study we compare how use of both spectral and spatial domain increase classification performance of convolutional neural networks. We compare five different neural network architectures for real patient data. Our models gain same or slightly better positive predictive value as clinicians. Towards more general and reliable model more data is needed and collection of training data should be systematic. peerReviewed
