I will explain how one can study orderability questions using the machinery of Rabinowitz Floer homology. We establish a link between orderable and hypertight contact manifolds, and show that the Weinstein Conjecture holds (i.e. there exists a closed Reeb orbit) whenever there exists a positive (not necessarily contractible) loop of contactomorphisms.http://www.math.ethz.ch/screen/info?guid=6111Tue, 18 Nov 2014 09:21:38 +0100Ya'acov Ritov - There are many trees in the forest<h2 color="grey">Colloquium: From Robust to High-dimensional Statistics: 50 Years of Statistics at ETH Zurich</h2><h1>There are many trees in the forest</h1><br /><font color="grey">Speaker:</font> Ya'acov Ritov, The Hebrew University of Jerusalem<br /><font color="grey">Location:</font> HG F 30 (ETH Zentrum)<br /><font color="grey">Start Date/Time:</font> 24 November 2014 @ 16:00http://www.math.ethz.ch/screen/info?guid=6296Tue, 18 Nov 2014 10:12:20 +0100Nikolas Geroliminis - A hierarchical control approach for large-scale traffic networks<h2 color="grey">Optimization and Applications Seminar</h2><h1>A hierarchical control approach for large-scale traffic networks</h1><br /><font color="grey">Speaker:</font> Prof. Dr. Nikolas Geroliminis, EPF Lausanne<br /><font color="grey">Location:</font> HG G 19.2 (ETH Zentrum)<br /><font color="grey">Start Date/Time:</font> 24 November 2014 @ 16:30<br /><br /><strong>Abstract:</strong><br />As cities around the world grow rapidly and more people through different modes compete for limited urban road infrastructure to travel, it is important to this space can be manage this space to improve accessibility for travelers. This research targets to operate traffic in future cities in a holistic way that was not possible until now. It tackles the problem of modeling and optimization in large-scale congested traffic networks with an aggregated realistic representation of traffic dynamics and route choice and multiple modes of transport. Mobility advances through the integration of big data, the understanding of multimodal patterns, the coordination and optimization of urban efficiency and sustainability for the travel of people and goods. This is challenging because cities are highly complex systems. This seminar will describe methodologies to model and understand the collective behavior for different types of urban systems. It will highlight under what physical properties the aggregated laws will provide reasonable description of congestion for single- and multi-modal systems. Ultimately, the goal is to develop optimization tools and investigate what type of real-time active traffic management schemes (congestion pricing, vehicle restriction, large scale traffic signal control) can improve mobility measures in a city for cities of different structures. We build a hierarchical feedback control network of multiple levels. The validation of the modeling methodologies and the traffic management schemes are conducted in various and complex city structures scenarios using data from field experiments and micro-simulations.http://www.math.ethz.ch/screen/info?guid=4436Tue, 18 Nov 2014 09:22:04 +0100
