Price Discrimination with Robust Beliefs

Thomas Alois Weber, Jun Han

This paper considers the problem of second-degree price discrimination when the type distribution is unknown or imperfectly specified by means of an ambiguity set. As robustness measure we use a performance index, equivalent to relative regret, which quant ...

Three-dimensional electrodes for dielectrophoretic applications

Kevin Keim

This thesis reports the use of metal-coated three-dimensional SU-8 electrodes for dielectrophoretic bio sensing and particle manipulation applications. Placing free standing three-dimensional electrodes in microfluidic channels, electric fields can be appl ...

A Fast, Reliable and Wide-voltage-range In-memory Computing Architecture

David Atienza Alonso, Marina Zapater Sancho, Alexandre Sébastien Julien Levisse, William Andrew Simon

In-Memory Computing (IMC) solutions, and particularly bitline computing in SRAM, appear promising as they mitigate one of the most energy consuming aspects in computation: data movement. In this work we propose a fast (2.4Ghz for bitwise operations and 2.4 ...

Gravity-Insensitive Flexure Pivot Oscillators

Simon Nessim Henein, Ilan Vardi, Etienne Frédéric Gabriel Thalmann, Mohammad Hussein Kahrobaiyan, Lennart Rubbert

Classical mechanical watch plain bearing pivots have frictional losses limiting the quality factor of the hairspring-balance wheel oscillator. Replacement by flexure pivots leads to a drastic reduction in friction and an order of magnitude increase in qual ...

Acoustic emission source detection and wave generation on a working plate using piezoelectric actuators

Xinchang Liu

In modern automated assembly lines, part feeders play an important role to separate and sort parts. Agility and flexibility are required to achieve a good yield for different types of parts. The common working principle is to vibrate a working plate driven ...

Streaming Robust Submodular Maximization: A Partitioned Thresholding Approach

Volkan Cevher, Slobodan Mitrovic, Ilija Bogunovic, Jakub Tarnawski, Ashkan Norouzi Fard

We study the classical problem of maximizing a monotone submodular function subject to a cardinality constraint k, with two additional twists: (i) elements arrive in a streaming fashion and (ii) m items from the algorithm’s memory might be removed after th ...

Everything You Always Wanted to Know about Multicore Graph Processing but Were Afraid to Ask

Willy Zwaenepoel, Baptiste Joseph Eustache Lepers, Jasmina Malicevic

Graph processing systems are used in a wide variety of fields, ranging from biology to social networks, and a large number of such systems have been described in the recent literature. We perform a systematic comparison of various techniques proposed to sp ...

Size-dependent sorting of C. elegans nematodes through an adjustable microfluidic filter structure

Martinus Adela Maria Gijs, Thomas Lehnert, Matteo Cornaglia, Li Dong

We introduce a new and simple microfluidic sorting device based on adjustable filter structures that can be easily tuned by external pressure for a specific size-dependent C. elegans worm sorting experiment. A single device can be used for selecting and so ...

Versatile size-dependent sorting of C-elegans nematodes and embryos using a tunable microfluidic filter structure

Martinus Adela Maria Gijs, Thomas Lehnert, Matteo Cornaglia, Li Dong

The roundworm Caenorhabditis elegans (C. elegans) is a powerful model organism for addressing fundamental biological questions related to human disease and aging. Its life cycle consists of an embryo stage, four larval stages that can be clearly distinguis ...

Stability Analysis of a Partitioned Fluid-Structure Thermal Coupling Algorithm

Pénélope Leyland, Ojas Joshi

Numerical multiphysics coupling is gaining more and more importance in engineering. Partitioned algorithms are among the most efficient methods to solve the coupled problem. However, they present some drawbacks, with the stability of the algorithm itself b ...

Partitioned Algorithms for Fluid-Structure Interaction Problems in Haemodynamics

Fabio Nobile, Christian Vergara

We consider the fluid-structure interaction problem arising in haemodynamic applications. The finite elasticity equations for the vessel are written in Lagrangian form, while the Navier-Stokes equations for the blood in Arbitrary Lagrangian Eulerian form. ...

Reconstruction of Large-Scale Phylogenies : Advances in Algorithms and Statistical Methods

Vaibhav Rajan

The evolutionary relationships between organisms or phylogenies are fundamental to biology. They are invaluable as guiding tools to mine, organize and exploit the enormous amounts of biological data in the post-genomic era. The advent of high-throughput se ...

Automated Detection and Delineation of Tree Structures in Noisy Micrographs

Germán González Serrano

Despite more than a century of research, we still lack a concise description of the different types of neurons in the brain. This is a result of their large variance in morphology and the time consuming reconstruction process. In this thesis we design nove ...

A Divide-and-Conquer Approach for Solving Interval Algebra Networks

Jingshi Li

Deciding consistency of constraint networks is a fundamental problem in qualitative spatial and temporal reasoning. In this paper we introduce a divide-and-conquer method that recursively partitions a given problem into smaller sub-problems in deciding con ...

When manufacturing capability exceeds control capability: The paradox of high precision products, or is it possible to assemble functional products out of components we are unable to measure?

Jacques Jacot, Fabien Bourgeois, Sandra Koelemeijer Chollet

Sorting and mating is a very common practice in high precision manufacturing, as well in the watch industry, biomedical or automotive industry. This strategy helps to increase the assembly yield, but is costly and time-consuming. The question is, when is i ...
