How We Use Wikipedia: Studying Readers' Behavior with Navigation Traces

In the information age, the Web and the growing global connectivity drastically simplified our access to information. Learning and fact-checking from online resources is nowadays part of our daily routine. Studying the dynamic associated with online conten ...

On design strategies for binary dielectric metasurfaces based on the Fourier modal method

Kévin Müller

Binary dielectric metasurfaces are arrays of sub-wavelength structures that act as a thin layer of artificial material. They are generally lossless and relatively simple to fabricate since only a single structuring step is required. By carefully designing ...

Embryonic lateral inhibition as optical modes: An analytical framework for mesoscopic pattern formation

Andrew Charles Oates, Jose Negrete Jr

Cellular checkerboard patterns are observed at many stages of embryonic development. We study an analytically tractable model for lateral inhibition and show that the steady states are analogous to optical phonons at the Gamma point, which have the wave nu ...

Rapid Deployment of Curved Surfaces via Programmable Auxetics

Mark Pauly, Mina Konakovic Lukovic, Francis Julian Panetta

Deployable structures are physical mechanisms that can easily transition between two or more geometric configurations; such structures enable industrial, scientific, and consumer applications at a wide variety of scales. This paper develops novel deployabl ...

Collision-Free Pattern Formation

Rachid Guerraoui, Alexandre David Olivier Maurer

Shoals of small fishes can change their collective shape and form a specific pattern. They do so efficiently (in parallel) and without collision. In this paper, we study the analog problem of distributed pattern formation. A set of processes needs to move ...

Ferroelectric charged domain walls in an applied electric field

Nava Setter, Alexander Tagantsev, Maxim Gureev, Pavel Mokry

The interaction of electric field with charged domain walls in ferroelectrics is theoretically addressed. Ageneral expression for the force acting per unit area of a charged domain wall carrying free charge is derived. It is shown that, in proper ferroelec ...

Origami - Folded Plate Structures

Hans Ulrich Buri

This research investigates new methods of designing folded plate structures that can be built with cross-laminated timber panels. Folded plate structures are attractive to both architects and engineers for their structural, spatial, and plastic qualities. ...

Reverse transfer of nanostencil patterns using intermediate sacrificial layer and lift-off process

Jürgen Brugger, Marc Antonius Friedrich van den Boogaart, Oscar Vazquez Mena

We propose a new process by which patterns produced by nanostencil lithography can be reversed, so that the final pattern on the substrate has the same contrast (filled or empty) as that of the stencil. In this process, the stencil pattern is first formed ...

Protocol objects and patterns for structuring reliable distributed systems

Benoît Garbinato

This thesis is at the crossing of object-orientation and reliable distributed systems, and contributes to integrate those two research fields. Existing distributed programming environments can be characterised according to whether they rely on object conce ...
