DESCRIPTION:Research: Nice detectors for ugly lattices\, Francisco Monteir
 o\n\nThis talk shows that it is useful to approximate a given random latti
 ce by one with a structure that allows a trellis representation and thus t
 rellis decoding. The problem of finding a quasi-orthogonal sublattice in a
  lattice is central for the solution to the problem. That problem is known
  in theoretical computer science as the _Quasi-Orthogonal Subset problem_ 
 (QOS) but had never been thoroughly researched as it was thought a theoret
 ical question lacking applications to real problems. The solution of this 
 problem was investigated as it is the key to design efficient trellis-base
 d receivers for MIMO communication systems.\n\nResearch:  Bringing The Nex
 t Billion Online: Computing Research For Developing Regions\, Ripduman Soh
 an\n\nThis talk introduces the idea of technological research for developi
 ng regions in three parts. I begin by outlining the case for this research
  and highlight the (interesting and different) challenges associated with 
 carrying out technical research in developing countries. I then provide so
 me (varied) examples of such work highlighting its impact. I conclude by o
 utlining some immediate areas of interest that overlap with the DTG ’s a
 reas of expertise.
