Coordination in a multi-cell multi-antenna multi-user W-CDMA system: a beamforming approach
2008
The problem of designing joint power control and optimal beamforming (JPCOB) algorithms for the downlink of a coordinated multi-cell WCDMA system is considered throughout this paper. In this case, the JPCOB design is formulated as the problem of minimizing the total transmitted power in the coordinated multi-cell system, subject to a certain quality of service requirement for each user. In this paper, the performance of two JPCOB algorithms based on different beamforming approaches is compared over the coordinated multi-cell system. The first one, obtains local beamformers by means of the well-known virtual uplink-downlink duality. In contrast, the second algorithm implements multi-base bea…
Can google trends and wikipedia help traditional surveillance? A pilot study on measles
2019
Introduction: Cases of measles in some European countries are increasing. The aim of this study is to find the correlation between Google Trends and Wikipedia searches and the real number of cases notified. Materials and Methods: The data on Internet searches have been obtained from Google Trends and Wikipedia. The reported cases of measles were selected from January 2013 until December 2018 for Google Trends and July 2015 until December 2018 from for Wikipedia. We have selected data from four European Countries: Italy, France, Germany and Romania. The data extracted from Wikipedia and Google Trends have been moved over time (Lag), one month in the future and one month in the past. Cross-co…
Tiedonkeruun hallinta esineiden internetissä
2016
Digitalisaatio tuo tullessaan suuria muutoksia käsitykseemme koneiden ja ihmisten vuorovaikutuksesta. Tämä vuorovaikutus syntyy erilaisten tietolähteiden tuottaman tiedon kautta. Tässä tutkielmassa tarkastellaan millaista tietoa tuotetaan ja miten suuria määriä numeerista tietoa tulisi tuottaa, jotta se olisi myöhäisemmässä vaiheessa käyttökelpoista. Digitalization brings major changes in the understanding about interactions between machines and humans. This interaction is created through knowledge of various sources of information produced. This thesis examines what information is produced and how large amounts of numerical data should produce in order to be useful at a later stage.
Towards Service-oriented 5G: Virtualizing the Networks for Everything-as-a-Service
2018
It is widely acknowledged that the forthcoming 5G architecture will be highly heterogeneous and deployed with a high degree of density. These changes over the current 4G bring many challenges on how to achieve an efficient operation from the network management perspective. In this article, we introduce a revolutionary vision of the future 5G wireless networks, in which the network is no longer limited by hardware or even software. Specifically, by the idea of virtualizing the wireless networks, which has recently gained increasing attention, we introduce the Everything-as-a-Service (XaaS) taxonomy to light the way towards designing the service-oriented wireless networks. The concepts, chall…
Benefits and Threats to Using Social Media for Presenting and Implementing Evidence.
2018
As a potential high-yield tool for disseminating information that can reach many people, social media is transforming how clinicians, the public, and policy makers are educated and find new knowledge associated with research-related information. Social media is available to all who access the internet, reducing selected barriers to acquiring original source documents such as journal articles or books and potentially improving implementation-the process of formulating a conclusion and moving on that decision. The use of social media for evidence dissemination/implementation of research has both benefits and threats. It is the aim of this Viewpoint to provide a balanced view of each. J Orthop…
Co-creation for Digitalization: A Study of Co-creation in Norwegian Business Clusters
2020
Part 2: Fourth Industrial Revolution; International audience; There is a growing emphasis on digitalization in research and business practice. The rapid progress in digital technologies compel firms to innovate and transform their businesses. One way to improve the capacity to innovate and transform is to cooperate with others. However, there is a general lack of research on how co-creation among businesses can facilitate digitalization. This qualitative study explores how co-creation among businesses can stimulate and facilitate digitalization.We have investigated co-creation activities involving companies in business clusters. This paper reports from a study of three business clusters in …
Comunicazione multidimensionale nella società glocale,
2004
In questo contributo ho innanzitutto esposto la teoria multidimensionale della comunicazione nelle sue linee essenziali; ho poi indicato i principi metodologici basilari che derivano da essa e che consentono di definire una tecnica di analisi applicabile a questo tipo di interfacce della comunicazione telematica tra agenti sociali. Ho pure cercato di dare risposta a tre questioni metodologiche – quale oggettività dei risultati, quale loro comparabilità e quale flessibilità della teoria multidimensionale stessa –, che sono emerse nello studio empirico dei siti internet di istituzioni pubbliche e di imprese (due degli ipertesto raccolti nel cd-rom allegato al volume, cioè "Regioni on line" e …
ImageRover: A Content-Based Image Browser for the World Wide Web
1997
ImageRover is a search-by-image-content navigation tool for the World Wide Web (WWW). To gather images expediently, the image collection subsystem utilizes a distributed fleet of WWW robots running on different computers. The image robots gather information about the images they find, computing the appropriate image decompositions and indices, and store this extracted information in vector form for searches based on image content. At search time, users can iteratively guide the search through the selection of relevant examples. Search performance is made efficient through the use of an approximate, optimized k-d tree algorithm. The system employs a novel relevance feedback algorithm that se…

Examination of robust D-stability of TCP-DCR protocol
2012
This paper presents non-linear mathematical model of a computer network with a part of wireless network. The article contains an analysis of the stability of the network based on TCP-DCR, which is a modification of the traditional TCP. Block diagram of the network model was converted to a form in order to investigate the D-stability using the method of the space of uncertain parameters. Robust D-stability is calculated for constant delays values.
