—Multimedia requirements of the 1990’s drove wired and optical network architects to reconsider the inefficiencies of packet switching and consider long proven methods such as...
Vertical partition is an important technique in database design used to enhance performance in database systems. Vertical fragmentation is a combinatorial optimization problem that...
The optimal sizing of a small autonomous hybrid power system can be a very challenging task, due to the large number of design settings and the uncertainty in key parameters. This ...

Wireless networks are currently experiencing more overload situations than their wireline counterparts because of explosive mobile traffic growth, unpredictable traffic behavior, s...
Abstract. We study two-stage, finite-scenario stochastic versions of several combinatorial optimization problems, and provide nearly tight approximation algorithms for them. Our pr...
