Selective Input Adaptation in Parametric Optimal Control Problems involving Terminal Constraints

Dominique Bonvin, Benoît Chachuat, Saurabh Anand Deshpande

This paper is concerned with input adaptation in dynamic processes in order to guarantee feasible and optimal operation despite the presence of uncertainty. For optimal control problems having terminal constraints, two sets of directions can be distinguish ...

Minimum distance between pattern transformation manifolds: Algorithm and Applications

Pascal Frossard, Effrosyni Kokiopoulou

Transformation invariance is an important property in pattern recognition, where different observations of the same object typically receive the same label. This paper focuses on a transformation invariant distance measure that represents the minimum dista ...

Geometry-aware analysis of high-dimensional visual information sets

Effrosyni Kokiopoulou

Over the past few decades we have been experiencing a data explosion; massive amounts of data are increasingly collected and multimedia databases, such as YouTube and Flickr, are rapidly expanding. At the same time rapid technological advancements in mobil ...

The role of perspective functions in convexity, polyconvexity, rank-one convexity and separate convexity

Bernard Dacorogna

Any finite, separately convex, positively homogeneous function on

\mathbb{R}^2

is convex. This was first established by the first author ["Direct methods in calculus of variations", Springer-Verlag (1989)]. Here we give a new and concise proof of this re ...

Measurement-based Run-to-run Optimization of a Batch Reaction-distillation system

Dominique Bonvin, Alejandro Gabriel Marchetti

Recently, measurement-based optimization schemes have been developed to deal with uncertainty and process variations. One of the methods therein, labeled NCO tracking, relies on appropriate parameterization of the input profiles and adjusts the correspondi ...

Time-critical multiresolution rendering of large complex models

Very large and geometrically complex scenes, exceeding millions of polygons and hundreds of objects, arise naturally in many areas of interactive computer graphics. Time-critical rendering of such scenes requires the ability to trade visual quality with sp ...

Fast and accurate modeling of waveguide grating couplers

Jan Sickmann Hesthaven

A boundary Variation method for the analysis of both infinite periodic and finite aperiodic waveguide grating couplers in two dimensions is introduced. Based on a previously introduced boundary variation method for the analysis of metallic and transmission ...

Real-time facial interaction

Daniel Thalmann

The human interface for computer graphics systems is evolving to involve a multimodal approach. It is now moving from keyboard operation to more natural modes of interaction using visual, audio and gestural means. This paper discusses real-time interaction ...

Referee assignment for volleyball championship: A competition between three local search heuristics

Thomas Liebling

We model the problem of assigning referees to matches of volleyball championships as a combinatorial optimization problem. To solve it, we adapt three local search heuristics and study their behavior as a funtion of their parameters. We show the limitation ...

Compressed Sensing and Adaptive Graph Total Variation for Tomographic Reconstructions

Pierre Vandergheynst, Nauman Shahid

Compressed Sensing (CS) and Total Variation (TV)- based iterative image reconstruction algorithms have received increased attention recently. This is due to the ability of such methods to reconstruct from limited and noisy data. Local TV methods fail to pr ...
