Lagrangian Relaxation for the Time-dependent Combined Network Design and Routing Problem

  • Bernard Fortz
  • Gorgone E.
  • Papadimitriou D.

In communication networks, the routing decision process (distributed and online) remains decoupled from the network design process, i.e., resource installation and allocation planning process (centralized and offline). To reconcile both processes, we ambition to design a distributed optimization technique aware of distributed nature of the routing process by decomposing the ...

Low-Level Frame-Buffer Scraping for GPUs in the Cloud

  • Carroll M.
  • Hadzic I.
  • Woithe H.

We describe and evaluate a software-only implementation of a novel mechanism for accessing and streaming GPU-rendered content from the cloud to low-end user devices. The unique properties of our implementation enable the trivial cloud-deployment of graphics-intensive applications, even ones that were not originally intended to run in the cloud. We ...

A Metric to Describe Access Point Significance in Location Estimation

  • Claussen H.
  • Dashti M.

Indoor localization is a key enabling technology for numerous location based services (LBS). A promising indoor localization technique is location fingerprinting (LF), having the major advantage of exploiting already existing radio infrastructures. LF estimates users location accurately providing reliable Rf fingerprints, that are unique and stable over time. We propose ...

A Steiner tree-based verification approach for handling topology changes in self-organizing networks

  • Ali-Tolppa J.
  • Carle G.
  • Sanneck H.
  • Tsvetkov T.

In today's Self-Organizing Networks (SONs) we differentiate between closed-loop functions, which have a predefined absolute goal, and such that form an action plan that achieves a high expected utility. Both function types perform changes to Configuration Management (CM) parameters, but only the second type may re-adapt the action plan in ...

Non-linear modeling for low and high power microwave transistors

  • Rafael-Valdivia G.

Video streaming services have continuously gained popularity over the last decades, accounting for about 70% of all consumer Internet traffic in 2016. All of these video streaming sessions have strict delivery deadlines in order to avoid playout interruptions, detrimentally impacting the Quality of Experience (QoE). However, the vast majority of ...

Electron pairing in the vast majority of superconductors follows the Bardeen-Cooper- Schrieffer theory of superconductivity, which describes the condensation of electrons into pairs with antiparallel spins in a singlet state with an s-wave symmetry. Unconventional superconductivity was predicted in single-layer graphene (SLG), with the electrons pairing with a p-wave or ...

On the Development of a Metric for Quality of Information Content over Anonymised Data-Sets
