Linking Objects in Videos by Importance Sampling

Daniel Gatica-Perez

We present an approach to create hyper-links between video segments that contain objects of interest, based on video structuring, object definition, and stochastic object localization in the video structure. Localization is formulated in the Metric Mixture ...

Stochastic Analysis of Some Expedited Forwarding Networks

Jean-Yves Le Boudec, Milan Vojnovic

We consider stochastic guarantees for networks with aggregate scheduling, in particular, Expedited Forwarding (EF). Our approach is based on the assumption that a node can be abstracted by a service curve, and the input flows are regulated individually at ...

Supplemental Information for the New Definition of the EF PHB

Jean-Yves Le Boudec

This document is intended to supplement [6]. Its primary motivation is providing additional explanation to the revised EF definition and its properties. The document also provides additional implementation examples and gives some guidance for computation o ...

An integral characterization of Hajlasz-Sobolev space

Marc Troyanov

We prove that the pointwise inequality used by P. Hajlasz in his definition of Sobolev spaces on metric spaces is equivalent to an integral (Poincaré-type) inequality. ...

Photo-oxidant formation in the Milan metropolitan area

Hubert van den Bergh, Bertrand Calpini, Valentin Simeonov, Alain Clappier, Gilles Larchevêque

During the Limitation of Oxidant Prodn. (LOOP) campaign, different instruments were deployed, providing a complete data set. This will be used to evaluate the model and its ability to reproduce pollution events. Then, the complete data set will be used for ...

High Order Balanced MultiWavelets: Theory, Factorization and Design

Martin Vetterli, Jérôme Lebrun

This paper deals with multiwavelets and the different properties of approximation and smoothness that are associated with them. In particular, we focus on the important issue of the preservation of discrete time polynomial signals by multiwavelet based fil ...

Energy flow in light-coupling masks for lensless optical lithography

Olivier Martin

We illustrate the propagation of light in a new type of coupling mask for lensless optical lithography. Our investigation shows how the different elements comprising such masks contribute to the definition of an optical path that allows the exposure of fea ...

A Contribution to 3D Digital Lines

We propose in this paper a new approach to three-dimensional digital lines (3DDLs) based on the study of the integer lattice generated by the projection of Z3 onto an euclidean plane which reduces the problem to dimension 2. The many properties of this lat ...

Heterojunction Band Discontinuities - a Fundamental Problem in Solid-State Science

Giorgio Margaritondo

Heterojunction band lineups have been investigated for over 40 years, and still are one of the most difficult open problems in condensed matter research-with an immediate impact on heterojunction devices. Steady progress has been made at least in understan ...
