The Papyrus Digital Library: Discovering History in the News

Abstract. Digital archives comprise a valuable asset for effective information retrieval. In many cases, however, the special vocabulary of the archive restricts its access only to experts in the domain of the material it contains and, as a result, researchers of other disciplines or the general public cannot take full advantage of the wealth of information it offers. To this end, the Papyrus research project has worked towards a solution which makes cross-discipline search possible in digital libraries. The developed prototype showcases this approach demonstrating how we can discover history in news archives. In this demo we focus on demonstrating two of the end user tools available in the prototype, the cross-discipline search and the Papyrus browser

RDOF: deployment optimization for function as a service

Function as a service (FaaS) simplifies the runtime resource management of cloud applications and enables finegrained scaling and billing at the function level, thus becoming the most widespread serverless paradigm today. Cost-effective use of FaaS entails appropriately deploying individual functions. We propose in this paper RDOF1 , a model-driven approach to deployment optimization for FaaS. RDOF predicts the performance of a FaaS-based application by instantiating a layered queueing network and finds the optimal configuration of each function such that the total operating cost is minimized under the specified performance requirements. We have validated RDOF on Amazon Web Services (AWS) and implemented it in an online tool that operates on TOSCA metamodels

A Priority Dropping Mechanism for the Multicast Delivery of Layered Video in a DiffServ Environment

Abstract:- In this paper a network-based, open loop mechanism for the multicast delivery of layered video streams is specified and experimentally evaluated for a DiffServ environment. Network oriented mechanisms for delivering layered multicast video offer simplicity and efficiency. Before the emergence of the Differentiated Services (DiffServ) framework a solid and feasible set of network mechanisms supporting such functionalities did not exist. The central idea is that once the application flow provides indications of how to scale in cases of losses, it is task of the network to manage packet drops according to their importance. The application defines priority layers within the video stream through packet marking, while the DiffServ is exploited to provide layer aware packet dropping together with a complete QoS provisioning framework. In this sense, each video stream is delivered in a single multicast group, without the need for extensive group management functions. During congestion at multicast tree nodes, packets corresponding to a lower priority layer are dropped first, thus protecting the most precious entities of the stream. In this context, congestion is handled at the node it occurs as soon as it occurs. Experiments with a DiffServ aware MPEG-4 streaming platform, were conducted over a laboratory platform validating the mechanism’s applicability. Experimental results are exposed.
