Application of vertex and mass constraints in track-based alignment

Olivier Schneider, Christophe Salzmann, Matthew Needham, Maurizio Martinelli, Frédéric Guillaume Dupertuis, Vincent Fave, Géraldine Conti, Louis Nicolas, Gerhard Raven

The software alignment of planar tracking detectors using samples of charged particle trajectories may lead to global detector distortions that affect vertex and momentum resolution. We present an alignment procedure that constrains such distortions by mak ...

Semantic Trajectories Modeling and Analysis

Stefano Spaccapietra, Christine Parent, Zhixian Yan, Maria Luisa Damiani, José Antonio Fernandes de Macedo

Focus on movement data has increased as a consequence of the larger availability of such data due to current GPS, GSM, RFID, and sensors techniques. In parallel, interest in movement has shifted from raw movement data analysis to more application-oriented ...

Method and apparatus for multiple object tracking with k-shortest paths

Pascal Fua, François Fleuret, Jérôme Berclaz

Trajectories of objects are estimated by determining the optimal solution(s) of a tracking model on the basis of an occupancy probability distribution. The occupancy probability distribution is the probability of presence of objects over a set of discrete ...

Analytical model for ultra-thin body junctionless symmetric double gate MOSFETs in subthreshold regime

Jean-Michel Sallese, Farzan Jazaeri, Adil Koukab, Lucian Barbut

In this paper, we propose an approximate solution to solve the two dimensional potential distribution in ultra-thin body junctionless double gate MOSFET (JL DG MOSFET) operating in the subthreshold regime. Basically, we solved the 2D-Poisson equation along ...

Real-Time Optimization for Kites

Dominique Bonvin, Grégory François, Sean Costello

Over the past decade, a large number of academics and start-ups have devoted them- selves to developing kites, or airplanes on tethers, as a renewable energy source. Determining the trajectories the kite should follow is a modeling and optimization challen ...

The Entropy of Conditional Markov Trajectories

Patrick Thiran, Matthias Grossglauser, Mohamed Kafsi

To quantify the randomness of Markov trajectories with fixed initial and final states, Ekroot and Cover proposed a closed-form expression for the entropy of trajectories of an irreducible finite state Markov chain. Numerous applications, including the stud ...

Electron beam apparatus

Jean Berney

A method suitable for preparing a specimen for inspection, the method comprising the steps of: irradiating a photocathode so that the photocathode emits electrons from a surface of the photocathode, wherein the emitted electrons each follow a trajectory, a ...

Within-Crowd Immersive Evaluation of Collision Avoidance Behaviors

Daniel Thalmann, Ronan Boulic, Junghyun Ahn, Nan Wang

In this paper, we first present our crowd simulation method, Trajectory Variant Shift (TVS) based on real pedestrian trajectories re-use. We detail how to re-use and shift these trajectories to avoid collisions while retaining the liveliness of captured da ...

FORWARD BROWNIAN MOTION

We consider processes which have the distribution of standard Brownian motion (in the forward direction of time) starting from random points on the trajectory which accumulate at -∞ 1. We show that these processes do not have to have the distribution of st ...

How good Gestalt determines low level vision

Michael Herzog

In classical models of vision, low level visual tasks are explained by low level neural mechanisms. For example, in crowding, perception of a target is impeded by nearby elements because, as it is argued, responses of neurons coding for nearby elements are ...
