Realizability of planar point embeddings from angle measurements
Majed El Helou, Adam James Scholefield, Frederike Dümbgen
Localization of a set of nodes is an important and a thoroughly researched problem in robotics and sensor networks. This paper is concerned with the theory of localization from inner-angle measurements. We focus on the challenging case where no anchor loca ...
2020Are Photonic Nanojets Achromatic?
Toralf Scharf, Myun Sik Kim, Michail Symeonidis
In this work we study the evolution of the photonic nanojet (PNJ) phenomenon as the ratio of the sphere's diameter over the illumination wavelength changes, for microspheres with diameters from 2 mu m to 100 mu m. We measure the focal point position by usi ...
SPIE-INT SOC OPTICAL ENGINEERING2019Effects of Pore and Cage Topology on the Thermodynamics of n-Alkane Adsorption at Bronsted Protons in Zeolites at High Temperature
Monte Carlo simulations are used to systematically investigate the effects of structural topology on the thermodynamics of n-alkanes adsorbed at Bronsted protons in zeolites having one-dimensional channel systems. In zeolites without cages, the enthalpy an ...
American Chemical Society2017Tailoring self-assembly and optoelectronic properties of organic semiconductors via macromolecular engineering
Conjugated polymers and small molecules are a promising class of semiconducting materials for application in macroelectronic and energy conversion devices. The development of high performance devices employing this class of semicrystalline materials ultima ...
EPFL2016Diameter Graphs in R-4
A diameter graph in is a graph whose set of vertices is a finite subset of and whose set of edges is formed by pairs of vertices that are at diameter apart. This paper is devoted to the study of different extremal properties of diameter graphs in and on a ...
Springer2014Obstacle-induced spiral vortex breakdown
Mohamed Farhat, François Gallaire, Matthieu Dreyer, Simon Pasche
An experimental investigation on vortex breakdown dynamics is performed. An adverse pressure gradient is created along the axis of a wing-tip vortex by introducing a sphere downstream of an elliptical hydrofoil. The instrumentation involves high-speed visu ...
Springer2014Finite Element Method on Riemann Surfaces and Applications to the Laplacian Spectrum
The objective of this PhD thesis is the approximate computation of the solutions of the Spectral Problem associated with the Laplace operator on a compact Riemann surface without boundaries. A Riemann surface can be seen as a gluing of portions of the Hype ...
EPFL2012New Results in the Theory of Linear and Integer Programming
The polynomial Hirsch conjecture states that the vertex-edge diameter of a d-dimensional polyhedron with n facets is bounded by a polynomial in d and n. For the special case where the polyhedron is defined as the set of points satisfying a system Ax ≤ b of ...
EPFL2012Quantitative Prediction Of Flow Patterns In Liquid-Liquid Flow In Micro-Capillaries
Lioubov Kiwi, Madhvanand Namadeo Kashid
Flow patterns in microstructured reactors (or microchannels) play an important role in dictating the mass transfer rates. In the present work, experiments were carried out to investigate the two phase (liquids) flow patterns in microchannels with different ...
