Automatic Calibration of Ultra Wide Band Tracking Systems Using A Mobile Robot: A Person Localization Case-study

Alcherio Martinoli, Zeynab Talebpour, Alessio Canepa

Ultra Wide Band (UWB) is an emerging technology in the field of indoor localization, mainly due to its high performances in indoor scenarios and relatively easy deployment. However, in complex indoor environments, its positioning accuracy may drastically d ...

Maxwell’s equations as a special case of deformation of a solid lattice in Euler’s coordinates

It is shown that the set of equations known as “Maxwell’s equations” perfectly describe two very different systems: (1) the usual electromagnetic phenomena in vacuum or in the matter and (2) the deformation of isotropic solid lattices, containing topologic ...

Teaching Analytics: Towards Automatic Extraction of Orchestration Graphs Using Wearable Sensors

Pierre Dillenbourg, Maria Jesus Rodriguez Triana, Kshitij Sharma, Luis Pablo Prieto Santos

"Teaching analytics" is the application of learning analytics techniques to understand teaching and learning processes, and eventually enable supportive interventions. However, in the case of (often, half-improvised) teaching in face-to-face classrooms, su ...

A New Converse Bound for Coded Caching

Michael Christoph Gastpar, Sung Hoon Lim, Chien-Yi Wang

An information-theoretic lower bound is developed for the caching system studied by Maddah-Ali and Niesen. By comparing the proposed lower bound with the decentralized coded caching scheme of Maddah-Ali and Niesen, the optimal memory--rate tradeoff is char ...

MATHICSE Technical Report : Structure-preserving low multilinear rank approximation of antisymmetric tensors

Daniel Kressner

This paper is concerned with low multilinear rank approximations to antisymmetric tensors, that is, multivariate arrays for which the entries change sign when permuting pairs of indices. We show which ranks can be attained by an antisymmetric tensor and di ...

Central Subalgebras Of The Centralizer Of A Nilpotent Element

Donna Testerman

Let G be a connected, semisimple algebraic group over a field k whose characteristic is very good for G. In a canonical manner, one associates to a nilpotent element X is an element of Lie(G) a parabolic subgroup P - in characteristic zero, P may be descri ...

Time-varying FRI Theory for Sound Source Localization

Ivan Dokmanic, Juri Ranieri, Helena Peic Tukuljac

In this report we present results of a Semester project in the Winter semester of 2015. The project focuses on exploration of FRI theory for 1D case and its generalization. This theory is further applied to sound source localization with extension to signa ...
