Orthogeodesic Point-Set Embedding of Trees

Radoslav Fulek, Fabrizio Frati

Let S be a set of N grid points in the plane, no two of which lie on the same horizontal or vertical line, and let G be a graph with n vertices (n

N° 2 Lighthouse Project 2e éd.

Dieter Dietz, Aline Dubach

The Lighthouse Project proposes a house. Named a House it had to address inhabitation: for whom was defined by each student. Additionally the Lighthouse had to include a public function. Light was considered as an attractor and conductor of flows in the ur ...

Liberalization and Competition in Postal Markets: Decentralized Infrastructure versus Cherry Picking

Martin Maegli

New entrants in postal markets usually set up delivery networks by concentrating on urban areas and large business customers. This implies that they operate their network highly centralized - at least in early phases of entrance. ...

A Topological Treatment of Early-Deciding Set-Agreement

Rachid Guerraoui, Bastian Pochon

The k-set-agreement problem consists for a set of n processes to agree on less than k among n possibly different Values, each initially known to only one process. The problem is at the heart of distributed computing and generalizes the celebrated consensus ...

Hierarchical diffusion algorithms for distributed estimation

Ali H. Sayed

We study the problem of distributed estimation, where a set of nodes are required to collectively estimate some parameter of interest from their measurements. Distributed implementations avoid the use of a fusion center and distribute the processing and co ...

Diffusion LMS algorithms with information exchange

Ali H. Sayed

We consider the problem of distributed estimation, where a set of nodes are required to collectively estimate some parameter of interest. We motivate and propose new versions of the diffusion LMS algorithm, including a version that outperforms previous sol ...

Amorphous hafnium silicates: structural, electronic and dielectric properties

Alfredo Pasquarello, Peter Broqvist

Models of amorphous (HfO2)x(SiO2)(1), for varying hafnium, content x are generated by ab initio molecular dynamics. The structural properties are analyzed in terms of pair distribution functions from which typical bond lengths and coordination numbers are ...

Multiscale modeling in advanced materials research: Challenges, novel methods, and emerging applications

William Curtin

The concept of multiscale modeling embodies the idea that a comprehensive description of a material will require an understanding over multiple time and length scales. A multiscale model requires that descriptions at all levels be consistent with each othe ...

Signal Reconstruction from Multiple Unregistered Sets of Samples using Groebner Bases

Martin Vetterli, Luciano Sbaiz, Patrick Vandewalle

We present a new method for signal reconstruction from multiple sets of samples with unknown offsets. We rewrite the reconstruction problem as a set of polynomial equations in the unknown signal parameters and the offsets between the sets of samples. Then, ...
