The optimal throughput order of wireless ad hoc networks and how to achieve it
In this paper, we study the contribution of network coding (NC) in improving the multicast capacity of random wireless ad hoc networks when nodes are endowed with multi-packet transmission (MPT)…
-
A general framework for the capacity analysis of wireless ad hoc networks
In this paper, we introduce a general framework for computing the throughput capacity of wireless ad-hoc networks under all kinds of information dissemination modalities.

Looking through the keyhole: snippet sharing in close collaborations
We demonstrate Keyholes, content annotations where authors or readers enter meta-data within a document to indicate what gets shared, with whom, and why.

Towards a model of understanding social search
Our main contribution is that we have integrated models from previous work in sensemaking and information seeking behavior to present a canonical social model of user activities before, during, and…

Laser Desorption Studies Using Laser-Induced Fluorescence of Large Aromatic Molecules
Pulsed laser desorption of non-volatile organic dye molecules paraterphenyl and tetra-t-butyl-p-quinquephenyl (QUI) was studied using gas phase ultraviolet laser induced fluorescence...

Planning and Learning Algorithms for Routing in Disruption-Tolerant Networks
We give an overview of algorithms that we have been developing in the DARPA disruption-tolerant networking program, which aims at improving communication in networks with intermittent and episodic connectivity.

Hydrogen Collisions in Planetary Atmospheres, Ionospheres, and Magnetospheres
Here we present a critical evaluation of the current state of understanding of the chemical reaction rates and collision cross sections for several important hydrogen collision processes in planetary atmospheres, ionospheres,…
