A huge amount of data is everyday produced, even in many critical business sectors, in a distributed, collaborative way withthe support of spreadsheet applications. the manual fusion of such data often yields errors: copy-paste operations, loss of alignment and coherency due to multiple spreadsheet copies or broken cross-spreadsheet links. these problems are partially addressed by two of the principal software platforms for collaboration: Microsoft SharePoint and Google Docs. After describing features and tools of the two platforms specifically designed for spreadsheet collaboration, pointing out differences and limitations, we propose SpreadComp, a spreadsheet composition platform based on three new collaboration patterns which span users and data interaction from the simplest flat scenario to more structured and hierarchical ones. We discuss the positioning of our collaboration patterns with respect to the analyzed existing approaches and we present the SpreadComp architecture and its prototype implementation.

this paper describes an Information-Centric Dataflow system that is based on name-based access to computation results, NDN PSync dataset synchronization for enabling consuming compute functions to learn about updates and for coordinating the set of compute functions in a distributed Dataflow pipeline. We describe how relevant Dataflow concepts can be mapped to ICN and how data-sharing, data availability and scalability can be improved compared to stateof-the-art systems. We also provide a specification of an applicationindependent namespace design and report on our experience with a first prototype implementation.

the amount of data collected in various IT systems has grown exponentially in the recent years. So the challenge rises how we can process those huge datasets withthe fulfillment of strict time criteria and of effective resource consumption, usually posed by the service consumers. this problem is not yet resolved withthe appearance of edge computing as widearea networking and all its well-known issues come into play and affect the performance of the applications scheduled in a hybrid edge-cloud infrastructure. In this paper, we present the steps we made towards network-aware big data task scheduling over such distributed systems. We propose different resource orchestration algorithms for two potential challenges we identify related to network resources of a geographically distributed topology: decreasing end-to-end latency and effectively allocating network bandwidth. the heuristic algorithms we propose provide better big data application performance compared to the default methods. We implement our solutions in our simulation environment and show the improved quality of big data applications.

In this paper, we extended the conventional space-time block-codes single-carrier frequency-domain equalization (STBC SC-FDE) to distributed STBC SC-FDE for practical implementation of cooperative networks. We proposed a SC-FDE transmission scheme over frequency-selective fading channels for distributed STBC cooperative network with amplify-and-forward relaying. We showed that the order-two spatial diversity gain achieved by this distributed STBC SC-FDE scheme. Linear receiver processing collects full spatial diversity, while the overall receiver complexity remains comparable to that of conventional without-relay-assisted transmissions over frequency-selective channels. Simulation results were also provided to validate the distributed STBC SC-FDE scheme.

Cloud computing has becoming the hotspot in the area of information technology. However, when indulging into its convenience and strong ability of the data processing, we also find that the great challenges also appear in terms of data security and privacy information protection. In this paper, on the one hand, the summary on the current security and privacy information challenges have been surveyed. Second, the current security measurements are summarized as well.

the significant resource requirements of distributed realtime multimedia applications often push today's system platforms to their limits. As a consequence, efficient, economic and adaptive management of resources is a major issue in distributed multimedia systems. this paper outlines a model-based time service encompassing three different aspects of time that are fundamental for sophisticated strategies within cross layer failure semantics, flow control, and synchronization.
