Seminar
Monday 27 Nov
Jean-Noël Monette, (Tacton Systems AB): CP for Product Configuration at Tacton
Location: ITC 1311, Time: 10:15

Abstract: Tacton is a world leader in product configuration, where a configuration engine is used to configure a complex product (e.g., a truck) in order to meet the users requirements (e.g., the truck should be used mostly on highways) and respect the established rules (e.g., compatibility between wheels and suspensions). A configuration engine helps the user by guiding him through the potentially huge space of feasible configurations (e.g, by presenting a default solution, by marking which values can be selected, or by resolving potential conflicts). To do so, the Tacton configuration engine maps configuration problems to constraint satisfaction problems (CSP) and uses an off-the-shelf constraint programming solver.

In this presentation, I will first present Tacton, what product configuration is, and how we help businesses be more effective. I will then describe and contrast existing approaches to product configuration, before focusing on Tacton's constraint-based solution.

Vi2 Seminar
Monday 27 Nov
Axel Ringh: Optimal Mass Transport as a Distance Measure between Images
Location: ITC 4307, Time: 14:15

Abstract: The optimal mass transport problem is a geometric framework for how to transport masses in an optimal way. Historically it has had large impact in economic theory and operations research, and recently it has also gained significant interest in application areas such as signal processing, image processing, and machine learning.

The optimal mass transport problem can be formulated as a linear programming problem, however when computing the distance between two images the size of this linear program becomes prohibitively large. A recently development to address this builds on using an entropic barrier term and solving the resulting optimization problem using so called Sinkhorn iterations. This allows for an approximate solution of large optimal mass transport problems. In this work we show how these results can be used and extended in order to use optimal mass transport for solving inverse problems in, e.g., computerized tomography.

Brahe Lecture
14 December
Björn Engquist, PhD (Univ. of Texas-Austin): Multiscale Modeling
Location: ITC 2446, Time: 15:15

You are all welcome to a the following lecture, as arranged by the Brahe educational foundation and sponsored by the Boston consulting group:

Speaker: Björn Engquist, PhD (Univ. of Texas-Austin)
Topic: Multiscale Modeling

This lecture will be introductory in approach and requires only some familiarity with basic numerical methods. In multiscale processes different phenomena interact on different scales in time and space. Computer simulations of such processes are challenging since the smallest scales must be accurately represented over domains that cover the largest scales. This results in a very large number of unknowns and prohibitingly long computing times. We will briefly discuss analytical techniques and then focus on numerical multiscale methods, which have been developed to overcome this difficulty. We will illustrate these technologies by the examples of turbulent flow and the coupling between molecular and continuum models. We will also discuss some connections between multiscale modeling, information theory and data compression.

Date & Venue:
14 December 2017 kl 15.15. at Uppsala University
ITC Campus, building 2, floor 4, room 2446.
Followed by reception in building 4, floor 3, room 4308
