An event-triggered distributed primal-dual algorithm for Network Utility maximization
Abstract— Many problems associated with networked systems can be formulated as network utility maximization (NUM) problems. NUM problems maximize a global separable measure of ne...

The Cost of Concurrent, Low-Contention Read-Modify-Write
In this work, we embark on a study of the possibility (or impossibility), and the corresponding costs, of devising concurrent, low-contention implementations of atomic Read-Modify...

Indexing Spatio-Temporal Trajectories with Chebyshev Polynomials
In this paper, we attempt to approximate and index a ddimensional (d 1) spatio-temporal trajectory with a low order continuous polynomial. There are many possible ways to choose ...
