Title: Enabling Digital Curation in the Context of Digital Repositories: Risk Assessment, Management and Mitigation
Today, a large fraction of Internet trafﬁc is originated by Content Delivery Networks (CDNs). To cope with increasing demand for content, CDNs have deployed massively distributed infrastructures. These deployments pose challenges for CDNs as they have to dynamically map end-users to appropriate servers without being fully aware of the network conditions within an Internet Service Provider (ISP) or the end-user location. On the other hand, ISPs struggle to cope with rapid traffic shifts caused by the dynamic server selection policies of the CDNs.
In his seminal paper, Myerson  provides a revenue-optimal auction for a seller who is looking to sell a single item to multiple bidders. Unfortunately, Myerson's auction generalizes to a limited range of domains, called "single-parameter", where each bidder's preference over the auction’s outcomes is specified by a single parameter. Indeed, extending this auction to "multi-parameter domains", such as selling multiple heterogeneous items to bidders, has been one of the most central problems in Mathematical Economics. We solve this problem.
We review the history of requirements analysis in Software Engineering, from early box-and-arrow notations, to goal-oriented models of stakeholder needs. We then present some of our recent work on designing agent-oriented software and adaptive systems by exploiting rich models of actors, their goals and social inter-dependencies. Throughout the discussion, we focus on the concepts used to model requirements, the analysis techniques that come with these concepts, and the design spaces the designer explores and she searches for solutions to a given requirements problem.
