Binomial heaps are data structures implemented as a collection of binomial trees, (A binomial tree of order K can be constructed from two trees of order (K-1)). They can implement several methods: Min, Insert, Union, ExtractMin, DecreaseKey and Delete. Fib ...
In this paper, we propose a novel approach for solving the reliable broadcast problem in a probabilistic model, i.e., where links lose messages and where processes crash and recover probabilistically. Our approach consists in first defining the optimality ...
We present the first fully dynamic algorithm for maintaining a minimum spanning forest in time o(sqrt(n)) per operation. To be precise, the algorithm uses O(n1/3 log n) amortized time per update operation. The algorithm is fairly simple and deterministic. ...
The distinct element method was originally designed to handle spherical particles. Here, this method is generalized to a wider range of particle shapes called spherosimplices. A contact detection method is given as well which uses weighted Delaunay triangu ...
Multi-hop hybrid networks can help providing both high bandwidth and broad coverage for wireless data networks. We focus on CSMA/CA-based networks and take IEEE 802.11 as a concrete example. We show that the three fundamental operations of synchronization, ...
We present in this paper a new complete method for distributed constraint optimization. This is a utility-propagation method, inspired by the sum-product algorithm. The original algorithm requires fixed message sizes, linear memory, and is time-linear in t ...
Self-stabilizing systems can automatically recover from arbitrary state perturbations in finite time. They are therefore well-suited for dynamic, failure prone environments. Spanning-tree construction in distributed systems is a fundamental task which form ...

The bi-directional plate bending behavior of a pultruded GFRP bridge deck system with orthotropic material and system properties was investigated by means of two full- scale experiments and numerical modeling. Furthermore, the maximum span of the deck betw ...
We are interested in finding a jointly optimal scheduling, routing and power control that achieves max-min fair rate allocation in a multi-hop wireless network. This is a highly complex non-convex optimization problem and it has been previously solved only ...
