While new paradigms such as Open Innovation [1] and Web 2.0 [2] as well as Living Labs operating as a User Centred Open Innovation Ecosystem [3] promote a more proactive role of users in the R&D process, a number of existing methods for involving users are described in the literature, such as Lead User [4], User Driven Innovation [4], User Centred Design [5] and User Created Content [1] as well...

This paper present a thorough and homogeneous comparison of chunk and peer selection strategies suitable for mesh-based, live, P2P streaming applications. Strategies are studied in a context of push protocols, and it is shown that none of the schedulers analyzed, which are, to the best of our knowledge, the majority of those proposed in the literature, offer acceptable performances on a range o...

In the context of an increasing demand for data and computational services, the benefits of cloud computing are substantial. However, cloud computing capabilities (as currently provisioned) can prove limited when accessed through a single provider. Extending capabilities of clouds by using user owned and provisioned devices can address a number of challenges arising in the context of current cl...

The dynamics of peers, namely Churn, is an inherent property of peer-to-peer (P2P) systems and is critical to their design and evaluation. Although every excellent P2P protocol has some solution to this issue, studies on Churn are still seldom. This paper studies various factors related to Churn, and uses them to analyze and evaluate P2P protocols. Prior researches on Churn are all based on the...

The music industry has struggled during the past decade due to file sharing and movie business executives fear the same fate. This paper seeks to provide measurements of the effects of peer-to-peer file sharing on the movie industry. We use a long panel of data at the country level containing information on theatrical, video rental, and video retail movie commercial performances, as well as Int...

While cybercrime proliferates – becoming more complex and surreptitious on the Internet – the tools and techniques used in performing digital investigations are still largely lagging behind, effectively slowing down law enforcement agencies at large. Real-time remote acquisition of digital evidence over the Internet is still an elusive ideal in the combat against cybercrime. In this paper we br...
