Density Decompositions of Networks

  • Borradaile G.
  • Migler T.
  • Wilfong G.

We introduce a new topological descriptor of a network called the density decomposition which is a partition of the nodes of a network into regions of uniform density. The decomposition we define is unique in the sense that a given network has exactly one density decomposition. The number of nodes ...

Small Transactions with Sustainable Incentives

  • Pianese F.
  • Sarkar S.
  • Signorini M.

The design of a successful distributed system for enabling payments and small transactions among Internet users has long been a major challenge in applied computer science. Bitcoin, the first cryptocurrency having reached world-wide popularity, suffers from sustainability problems such as inefficient energy expenditure for its network operation and from perverse ...

Person Recognition Beyond The Visible Spectrum: Combining Body Shape and Texture from mmW images

  • Fierrez J.
  • Gonzalez E.
  • Gonzalez-Sosa E.
  • Patel V.
  • Vera-Rodriguez R.

Biometrics have been tradittionally based on images acquired in the visible spectrum. In this paper, we will go first into details regarding the regions beyond the visible spectrum that have been already explored in the literature for biometrics to overcome some of the limitations found in the visible region. Later, ...

Model-free resource management of cloud-based applications using reinforcement learning

The digital system of the future will face the growing challenge of controlling the system behavior in complex dynamically evolving environments. In this paper, we examine the applicability of a new management paradigm based on Reinforcement Learning approach, where no preliminary specification of the system model is required. In contrast, ...

A big switch abstraction to support service function chaining in cloud infrastructure

The concept of Service Function Chaining and Network Functions Virtualisation provides a great degree of flexibility for the rapid deployment of new services in service providers' environments.
