Bushwhacking Through Anaconda-Filled Jungles

Laboratory testing the Anaconda.

Laboratory measurements of the performance of the Anaconda are presented, a wave energy converter comprising a submerged water-filled distensible tube aligned with the incident waves. Experiments were carried out at a scale of around 1:25 with a 250 mm diameter and 7 m long tube, constructed of rubber and fabric, terminating in a linear power take-off of adjustable impedance. The paper presents...

Tarzan: Communicating and Moving in Wireless Jungles

Wireless networks allow portable/mobile devices (and the related applications) to communicate each other with radio or infrared signals. Computations on those networks are very sensible to many physical variables (e.g., energy consumption, distance, geographic topology, etc.). We propose Tarzan, a framework based on graph rewriting that easily allow one to express many quantitative aspects of w...

Modular and Mechanistic Analyses of Cellular Networks: Can We Navigate Through Molecular Jungles?

The deciphering of the genome has generated a list of the macromolecular parts of living cells. A challenge for systems biology is to understand how this " genetics parts " list gives raise to a space and time varying cellular behavior resulting from dynamic interactions within cellular signaling, metabolic, and gene networks. Advances in high-throughput genomics and proteomics analyses have en...

Jungles, bundles, and fixed parameter tractability

We give a fixed-parameter tractable (FPT) approximation algorithm computing the pathwidth of a tournament, and more generally, of a semi-complete digraph. Based on this result, we prove the following. • The Topological Containment problem is FPT on semi-complete digraphs. More precisely, given a semi-complete n-vertex digraph T and a digraph H, one can check in time f(|H|)n log n, where f is so...
