Gossip, or epidemic, protocols have emerged as a highly scalable and resilient approach to implement several application level services such as reliable multicast, data aggregation, publish-subscribe, among others. All these protocols organize nodes in an unstructured random overlay network. In many cases, it is interesting to bias the random overlay such that it better matches the underlying n...

Spiral overlays, for use with powder diffraction patterns and diffraction spacing profiles, can be at once forgiving of uncertainties in camera constant calibration and (once these are dealt with) sensitive to very small differences in lattice parameter. By facilitating comparison of different lattices in a common physical metric (namely a diffraction experiment of fixed camera constant and sca...

1 Overview Multiple related displays and windows are common in monitoring and business environments where the user is trying to integrate different data views into a coherent information picture. Our particular application is the design of efficient visualizations for the management and operation of high-performance buildings, and our users are the planners and building operators responsible fo...

In the repercussions of latest worldwide financial crisis that have occurred due to corona virus reasons (COVID-19); unprecedented stressful economic conditions prevailed, coupled with significant recessionary waves reasoned imposed strict lock downs adversely affected most sectors across globe. Based on such adverse conditions, and as banks were used calculate their Expected Credit Losses (ECL...

A Telco-CDN can be regarded as an intra-domain overlay network with tight resources and critical deployment constraints. This paper addresses two problems in this context: (1) the construction of the overlays used to deliver the video channels from the entrypoints of the Telco-CDN to the appropriate edge servers; and (2) the allocation of the required resources to these overlays. Our ultimate g...
