On the Burst Erasure Capability of Spatially Coupled LDPC Ensembles

  • Aref V.
  • Rengaswamy N.
  • Schmalen L.

Spatially-Coupled LDPC (SC-LDPC) ensembles achieve the capacity of binary memoryless channels, asymptotically, under belief-propagation decoding. In this work, we are interested in the finite-length performance of these ensembles on binary channels with memory. We study the average performance of random regular SC-LDPC ensembles on the single block erasure channel and ...

The Future of Communications

  • Hofmann M.
  • Lee A.
  • Olofsson B.

The essence of communication is the imparting or exchanging of information. We can broadly define three primary types of communication personal, media, and control type communication, each of which results in the exchange of information between people or systems. Personal communication can be regarded as the exchange of information or ...

Advertising Competitions in Social Networks

  • Masucci A.
  • Silva Allende A.

In the present work we study the advertising competition of several marketing campaigns who need to decide how many resources to allocate to potential customers to advertise their products through direct marketing while taking into account that competing marketing campaigns are trying to do the same. Potential customers express a ...

Next-Generation Forward Error Correction: Can we Close the Gap to the Shannon Limit?

  • Aref V.
  • Roesener D.
  • Schmalen L.
  • Suikat D.

We report the current status of forward error correction schemes and show how close we can operate to some theoretical limits taking into account the size of the codes. We show that spatially coupled LDPC codes are good candidates for bridging the gap to capacity and compare some practical codes ...

IoT - Impact on Mobile Networks

  • Dhingra V.

IoT is poised to revolutionize industries and ways we live and work. These things will digitally connect to other devices and the network via multiple technologies. MNOs are making significant investments in M2M communications for providing connectivity as well as value added services to IoT application providers and enterprises. However, ...

The Future of Information

  • White C.

We sit on the cusp of a revolution in information driven by the intersection of a massive increase in the sources of data and the ability to augment our intelligence and use critical thinking to turn this data into knowledge. Information can be defined as the communication or reception of ...

An Approach for Call Logs Anonymization Using Machine Learning

  • Denoyer Ludovic
  • Gallinari Patrick
  • Maag M.

Today it is difficult and in most of the cases it is impossible for a data owner to release call logs in a completely safe environment without any risk of individuals re-identification. However, call logs analysis is very important for research purposes or for marketing applications. Moreover, since the arrival ...

A dimensional comparison between embedded 3D-printed and silicon microchannels

  • Jeffers N.
  • O'Connor J.
  • Punch J.
  • Stafford J.

The subject of this paper is the dimensional characterization of embedded mi- crochannel arrays created using contemporary 3D-printing fabrication techniques. Conven- tional microchannel arrays, fabricated using deep reactive ion etching techniques (DRIE) and wet-etching (KOH), are used as a benchmark for comparison. Rectangular and trapezoidal cross-sectional shapes were investigated. The ...

NNET: a Socket API and protocol stack for Process-to-Content Network Communication

  • Gallo M.
  • Lin Gu
  • Perino D.
  • Varvello M.

Inter-Process Communication (IPC) refers to the set of methods which enable data exchange among processes. When two processes are remote, or run on machines connected via a network, IPC is realized through the socket interface and the networking protocol stack implemented at end-hosts. Today, most computer networks rely on the ...

Investigation of Vapour Chamber Performance with a Concentrated Heat Source

  • Kempers R.
  • Ravache E.
  • Robinson A.
  • Siedel S.

This work aims to characterize the performance of a commercially available solid heat sink (SHS) and a vapour chamber heat sink (VCHS) with a small localized heat source. The heat sinks were tested under forced convection conditions in a dedicated wind tunnel. Heat transfer and temperature measurements facilitated the estimation ...
