info  HGS MathComp Romberg Inauguration Lecture: Locating the Middle - The Art and Science of Mathematical StatisticsProf. Donald RichardsJan. 15, 2014, 17:15ECTS-Points: 0
Abstract, registration & information:
The Roman poet Ovid (43 BC – AD 17/18) wrote eloquently that in life, \"Medio tutissimus ibis\": \"You will go safest in the middle.\" But where is the middle to be found, and how do we know when we have found it? These questions are difficult to answer if only because the search for the middle requires that we hold in check our basic human impulses.

In this inaugural lecture, I will elucidate the importance of searching for the middle in several contexts. I will provide examples of ways of proceeding cautiously through life, instances from the process of scientific discovery, and illustrations from research in mathematical statistics.

In the case of mathematical statistics, I will demonstrate connections between the search for the middle and many problems in the integral calculus that I have studied for the past 35 years.

Abstract, registration & information:
I will present quantitative results for the stochastic
homogenization of linear elliptic equations with random coefficients in a discrete setting. Classical qualitative homogenization theory states that on large length scales the random coefficients can be replaced by homogenized coefficients that are deterministic and constant in space.
The homogenized coefficients are characterized by a formula that involves the solution to the so called \"corrector problem\". In contrast to periodic homogenization, in the stochastic setting the corrector problem is a highly degenerate elliptic equation on a probability space.
In this talk I will explain how to obtain various optimal estimates on the corrector, on approximations of the homogenized coefficients and on the homogenization error based on quantification of ergodicity. The talk is based on joint work with A. Gloria (Université Libre de Bruxelles) and F. Otto (MPI Leipzig).

Abstract, registration & information:
Abstract:
This is a slightly unusual talk but we think the audience will enjoy the following three related presentations. The first speaker, Florian Jug, will start by showing some biological data in order to make the point that BioImaging is essential for gaining insights into underlying biological processes. It will be apparent that segmentation, matching, and tracking are of central importance for most questions to be answered. The second part of our talk, held by Dagmar Kainmüller, gives one concrete and detailed example of a recently developed matching procedure we call \"Active Graph Matching\". This method combines the well-established Active Shape Models and graph matching, more precisely with wide baseline matching via dual decomposition. We successfully applied Active Graph Matching for the task of simultaneous segmentation and annotation of nuclei in C. elegans larvae. In the last part of our presentation, Carsten Rother will briefly introduce the Computer Vision Lab Dresden. He will also present some initial results on projects which run in his group, which are mainly about correspondence problems in RGBD images and on detection and pose estimation of chairs and other objects (joint work with Oxford University)

info  Delay Differential Equations in Population Biology and Epidemiology (abstract attached)Dr. Maria Vittoria BarbarossaJan 28, 2014 14:15ECTS-Points: 0
Abstract, registration & information:
In contrast to Ordinary Differential Equations (ODEs), Delay Differential Equations (DDEs) allow for the inclusion of past actions into mathematical models, thus making the model closer to the real-world phenomenon. Most of the results on DDEs have been developed only in the last fifty years (Kuang, 1993), however there is not yet such a comprehensive theory, as for ODEs. In particular, big challenges are given by equations with state-dependent delay. For this kind of problems, indeed, there is nowadays no unified theory, but rather results worked out on the basis of particular classes of equations (Hartung et al., 2006). Applications of DDEs with state-dependent delay is a very modern topic in mathematics and might offer the chance for significant steps forward.
In this talk we will present several applications of delay differential equations with constant and state- dependent delay in the fields of population dynamics and mathematical epidemiology:
• In the context of population dynamics, DDEs with constant delay can be obtained, e.g., from the balance laws of age-structured population dynamics, assuming that birth rates and death rates, as functions of age, are piece-wise constant. The delay arises naturally from biology as the age-at- maturity of individuals. We shall see applications of this modeling approach in population dynamics of isolated populations (Barbarossa et al., 2013), interplay of predators and prey (Mohr et al., 2013), tumor modeling (Barbarossa et al., 2012), as well as for the control of mosquitoes by mean of sterile insect technique.
• In epidemiology a delay can represent for example the duration in time of incubation or time a host stays infected. However, delay equations can be also used to investigate the phenomenon of waning immunity. When the body gets infected by a virus, indeed, the immune system develops a certain resistance against it. As a matter of fact disease-induced immunity tends to wane and, long time after recovery, an individual might become again susceptible to the virus. Exposure to the pathogen boosts the immune system, thus prolonging the time in which the individual is immune (Heffernan et al., 2009). We shall model the feedback mechanism which makes possible for certain individuals to have lifelong immunity, being regularly exposed to the infection.

Abstract, registration & information:
We simulate slightly viscous turbulent low Mach number 3d bluff body flow (including streamlined bodies) by computational solution of the incompressible Navier-Stokes equations with a slip boundary condition modeling observed small skin friction, by using a residual stabilized adaptive finite element method, referred to as Direct Fem-Simulation since no turbulence model beyond automatic residual stabilization is used. We find by duality based a posteriori estimation that mean value quantities such as drag and lift are computable to accuracies comparable to experiments. As a key example, we show that the turbulent flow around a complete airplane is computable and inspecting solutions leads to a new theory of flight essentially different from the accepted theory by Kutta-Zhukovsky-Prandtl developed 100 years ago. We find that turbulent bluff body flow in general can be described as potential flow modified by rotational slip separation as a flow which is resolvable computationally using millions of mesh points, except in a far-field wake of little influence on lift and drag, and also is understandable through a mathematical stability analysis.
