A Technical Approach to the Energy Blockchain in Microgrids
2018
The present paper considers some technical issues related to the “energy blockchain” paradigm applied to microgrids. In particular, what appears from the study is that the superposition of energy transactions in a microgrid creates a variation of the power losses in all the branches of the microgrid. Traditional power losses allocation in distribution systems takes into account only generators while, in this paper, a real-time attribution of power losses to each transaction involving one generator and one load node is done by defining some suitable indices. Besides, the presence of P–V nodes increases the level of reactive flows and provides a more complex technical perspective. For this re…
An analysis of ego network communities and temporal a affinity for online social networks
2017
The wide diffusion of Online Social Networks (OSNs) presents several advantages, like the definition of simple tools for information sharing and spreading. However, OSNs present also some drawbacks, one of the most important one is the problem of privacy disclosures. Distributed Online Social Networks (DOSNs), which decentralize the control of the social network, have been recently proposed to overcome these issues. The decentralization of the control has issued several challenges, one of the main ones is guaranteeing data availability without relying on a central server. To define users’ data allocation strategies, the knowledge of the structure of the ego network and of the user’ temporal…
A Peer-to-Peer Market Algorithm for a Blockchain Platform
2020
In an era of technological revolution in which everything becomes smarter and connected, the blockchain can introduce a new model for energy transactions able to grant more simplicity, security and transparency for end-users. The blockchain technology is characterized by a distributed architecture without a trusted and centralized authority, and, therefore, it appears as the perfect solutions for managing exchanges between peers. In this paper, a market algorithm that can be easily transferred to a smart contract for maximizing the match between produced and consumed energy in a micro-grid is presented. The algorithm supports energy transactions between peers (both producers and consumers) …
Music piracy culture in the Internet
2011
The purpose of the research was to identify the motivations and opinions on copyright and online music piracy on the Internet through Peer-to-peer (P2P) Networks. The research was carried out as a Master's Thesis in the Digital Culture program at the University of Jyväskylä. Quantitative research methodology was utilized in the form of questionnaires, which were distributed for two weeks through the mailing list and personal invitations at the University of Jyväskylä. 48 responses from people of 22 nationalities were received. Analysis of the questionnaires revealed opinions that people conduct music file sharing on P2P networks because it is convenient, promotes musicians and is environmen…
Savstarpējo aizdevumu (peer-to-peer lending) platformu darbības regulējuma problemātika Latvijā.
2021
Finanšu tehnoloģiju straujā attīstība radījusi bezprecedenta situāciju, kurā ieguldījumi finanšu instrumentos pieejami ikvienam – nepieciešama vien pieeja internetam un nedaudz naudas. Līdzīgi lielai daļai Eiropas valstu Latvija uz jaunā koncepta finanšu pakalpojumiem nav spējusi reaģēt operatīvi - Latvijas jurisdikcijā pēdējo piecu gadu laikā reģistrēts liels skaits kolektīvās finansēšanas platformu, kas bez atbilstošas licences interesentiem sniedz ieguldījumu pakalpojumus. Analizējot spēkā esošos normatīvos aktus un pētot Latvijas savstarpējo aizdevumu platformu tirgu, autore raksturo neviennozīmīgos savstarpējo aizdevumu platformu darbības juridiskos aspektus, kā arī skaidro, salīdzina …
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…
