Groundbreaking Ceremony Held for New ECE Building by TOM MOONE
NEWS FOR ECE ILLINOIS ALUMNI AND FRIENDS WINTER 2011 Also in this issue: New Assured Cloud Computing Center to be established at Illinois Groundbreaking Solar Decathlon: Helping students and the world ceremony held Alumnus Michael McCorquodale is the first ECE Engineer for new ECE building in Residence Department of Electrical and Computer Engineering Breaking ground on the future Dear alumni and friends, I have good news! The dream of a new building for our department, after many years of planning and anticipation, is now becoming a reality. Last month’s groundbreaking of the new ECE building marks the beginning of a new era for our department, a department of global influence and impact, thanks to the excellence of its faculty and alumni. And it is this global impact that makes this groundbreaking special not only for our department, our college, our campus, and our university, but also for the state of Illinois, our nation, and the world. Our faculty and our alumni have been among the pioneers of the major technological innovations that are the bedrock of today’s computing and communication technologies. The marvel of the computing technology and the communications infrastructure we enjoy today, and its catalytic role in improving living standards around the globe, would not have been possible without John Bardeen’s invention of the transistor or Jack Kilby’s brilliant idea of the integrated circuit. These Nobel Prize-winning innovations by two giants of the ECE ILLINOIS community have been followed by many more groundbreaking advances by ECE faculty and alumni, advances that inspire and drive our quest for a sustainable future for all. -

Convergence-2020.Pdf
A universal architecture to anonymize any application or protocol and turn it into an independent decentralized p2p network inside browsers and servers, with browsers acting as servers CONVERGENCE 1. Description This proposal is a complete redesign of our initial Convergence proposal from 2015 (http://www.peersm.com/Convergence.pdf ) which was intended as a research study for an EU call By “Convergence” in this proposal we don’t refer to a specific network or node but to methods using the Convergence principles 1.1 Background and rationale The initial Convergence proposal was written based on the observation that we must invent one network/system per need if we want to evade big data centralization and protect privacy/anonymity: to browse, to chat, to email, to exchange files, to do social networking or cooperative work, to do crypto currency, to protect the users from their connected objects, to handle peer identities. So it did envision the support of any type of applications and protocols on top of a secure anonymization system, inside browsers and servers The first part is very exactly what IPFS did, including the crypto currency concept in our proposal to sustain the network (Filecoin) But IPFS is not at all designed for privacy, the IPFS team knows that they will have to address the issue but it’s not even part of their roadmap And IPFS adoption is not for all protocols, many other networks will not use it and lack privacy too That’s why we are proposing the Convergence concepts, which are still very up to date, with a major novelty: -

Comparison of Data Transfer Performance of Bittorrent Transmission Protocols
Cumhuriyet Science Journal CSJ e-ISSN: 2587-246X Cumhuriyet Sci. J., Vol.40-3(2019) 762-767 ISSN: 2587-2680 Comparison of Data Transfer Performance of BitTorrent Transmission Protocols Halil ARSLAN 1,* , Özkan CANAY 2 1 Cumhuriyet University, Engineering Faculty, Dept. of Computer Engineering, Sivas, TURKEY 2 Sakarya University, Adapazarı Vocational School, Dept. of Computer Technologies, Sakarya, TURKEY Received: 19.09.2018; Accepted: 04.09.2019 http://dx.doi.org/10.17776/csj.461655 Abstract. BitTorrent, one of the distributed file sharing protocols, is regarded as one of the first examples of decentralized Internet philosophy and is among the important research areas in this context. TCP was initially used as the transport layer protocol in BitTorrent, and the transition to the uTP protocol was made because of the problems of latency and excessive bandwidth consumption. Later, with WebTorrent, which is a BitTorrent protocol adapted to the web, WebRTC was proposed as a transport layer protocol. Thus, BitTorrent protocol is enabled to work directly through Internet browsers without using any plugin. In this study, the data exchange sizes in the torrent shares of these three transmission protocols have been compared and the advantages and disadvantages of these protocols were demonstrated in this context. Keywords: BitTorrent, WebTorrent, TCP, uTP, WebRTC. BitTorrent İletim Protokollerinin Veri Aktarım Başarımlarının Karşılaştırılması Özet. Dağıtık dosya paylaşım protokollerinden BitTorrent, merkezi olmayan internet felsefesinin ilk örneklerinden olarak kabul edilmekte ve bu bağlamda önemli araştırma alanları arasında yer almaktadır. BitTorrent’te iletim katmanı protokolü olarak başlangıçta TCP kullanılmış, gecikme ve bant genişliğinin aşırı tüketilmesi problemlerinden dolayı uTP protokolüne geçiş yapılmıştır. -

David Miguel dos Santos Dias Examination Committee Chairperson: Prof. Dr. Ricardo Jorge Fernandes Chaves Supervisor: Prof. Dr. Lu´ıs Manuel Antunes Veiga Member of the Committee: Prof. Dr. Joao˜ Nuno de Oliveira e Silva October 2019 Acknowledgments The completion of my master thesis remains as one of the toughest projects I have yet executed. Having caught me in the roughest phase of my life, my initial investment to the project was hindered. It required a tremendous amount of perseverance and determination to complete while working a full-time job. I would have given up if it was not for the support of the people close to me and for this, I have to thank you all. To my beloved girlfriend, Joana Canhoto, you are my biggest motivation in life. You challenge me to do better everyday. Hadn’t I met you, I’m sure I would not have finished the thesis. I have to thank you for the countless hours of FaceTime, supporting me until we would both fell asleep. A special thank you to my teacher and supervisor, Professor Lu´ıs Veiga, who has shown to have incredible patience, giving me the time to finish my thesis. His availability for feedback, genuine interest and excitement for the project made this all possible. I want to massively thank my family for the support and for allowing me to go to college even when the circumstances were not the best and we struggled so much. -
Whitepaper: Public Whitepaper Release to Consider Feedback and Improve Proposal Design
WeYouMe is a peer-to-peer decentralized social media protocol. WeYouMe enables users to own their own data, to create posts to connect with their audience, message their friends, and earn digital currency rewards for sharing valuable content. The protocol leverages a participatory approach to community driven content moderation, a Delegated Proof of Stake and Proof of Work hybrid consensus mechanism, and enables a multi-application approach to create a neutral public square. The WeYouMe Mobile Application and Web Applications are the flagship social platforms of the WeYouMe network. They pack a suite of fun and creative new content types, and digital currency features. Users can share any type of content with their friends, peers, and the world by making posts to the WeYouMe blockchain. It will be free to use, open source, borderless, neutral, and censorship resistant. The network will reward users for posting content, voting on content, and contributing resources. The WeYouMe team will launch the WeYouMe Mainnet blockchain, and will create an ecosystem of cross platform compatible and open source applications that operate on the protocol. It will offer a comprehensive digital currency wallet and trading platform, with a decentralized and open marketplace of digital assets, services, and products. It will also integrate a native advertising network, and account memberships to deliver on-chain verifiable cash flows to buyback assets as protocol revenue. Contents: 1.
