Method for retrieving data from Ultra Wideband radio transmission signals

Jean-Yves Le Boudec, Ruben Merz, Manuel Flury

The present invention concerns a receiver and a method for retrieving data from Ultra wideband radio transmission signals received by a receiver and transmitted in packets containing at least a preamble known to the receiver and a payload containing data u ...

Towards in-flight quality assessment of airborne laser scanning

Jan Skaloud, Phillip Tomé

One of the main problems of today's ALS is the lack of reliable data quality assessment within or shortly after the airborne survey campaign. The paper presents an in- flight quality monitoring tool that allows assessing the quality of the recorded data "o ...

LSH At Large - Distributed KNN Search in High Dimensions

Karl Aberer, Sebastian Michel, Parisa Haghani

We consider K-Nearest Neighbor search for high dimensional data in large-scale structured Peer-to-Peer networks. We present an efficient mapping scheme based on p-stable Locality Sensitive Hashing to assign hash buckets to peers in a Chord-style overlay ne ...

Sensor Metadata Management and its Application in Collaborative Environmental Research

Karl Aberer, Michael Lehning, Sebastian Michel

This paper considers metadata generation and tracking in a collaborative environment where users publish raw sensor data in the form of virtual sensors and post-process data by means of filtering, modeling, or query processing techniques. In the metadata s ...

Compressive Sensing For Sensor Calibration

Volkan Cevher

We consider a calibration problem, where we determine an unknown sensor location using the known track of a calibration target and a known reference sensor location. We cast the calibration problem as a sparse approximation problem where the unknown sensor ...

An UrbanSim Model of Brussels in a Short Timeline

Michel Bierlaire

UrbanSim is an increasingly popular integrated transportation land-use model. A particularly attractive feature of UrbanSim is its disaggregate frame of analysis. This characteristic means it requires much land-use and socio-economic data at a fine scale. ...

From Bioinformatic Web Portals to Semantically Integrated Data Grid Networks

Karl Aberer, Philippe Cudré-Mauroux, Adriana Budura

We propose a semi-automated method for redeploying bioinformatic databases indexed in a Web portal as a decentralized, semantically integrated and service-oriented Data Grid. We generate peer-to-peer schema mappings leveraging on cross-referenced instances ...

Powder diffraction studies on proteins: An overview of data collection approaches

Philip Pattison

Following the seminal work of Von Dreele, high quality powder X-ray diffraction studies on proteins are being established as a valuable complementary technique to single-crystal measurements. Several studies using a variety of experiments approaches have b ...
