Twin particles and their love-hate relationship: An experimental study on shape-dependent particle pair interactions in confined Stokes flow

This thesis describes a study into pairwise particle interactions within a Hele-Shaw geometry, using stop-flow lithography. By exposing a photoreactive mixture to a strong UV-pulse, a hydrogel is formed. The shape of this hydrogel is controlled by masking part of the light beam. This process takes place while the Hele-Shaw channel is placed on...

Analysing jet breakup: An experimental study on Rayleigh-Plateau instability and subsequent droplet formation

This report aimed to investigate jet-breakup through nozzles and its dependencies on viscosity, flowrate and nozzle diameter. By measuring the transition point from dripping to jetting as a function of nozzle diameter and viscosity, it was found that increasing nozzle diameters require increasing flowrates to reach jetting mode, while increasing...

A Resiliency-First Approach to Distributed DAG Computations

A framework is introduced for computations with transformations on immutable data. Inspiration is taken from Apache Spark, however the model of computation is generalized from an emphasis on narrow and wide dependencies, to an arbitrary set of transformations that form a directed acyclic graph (DAG). A distributed scheduling algorithm is...

An Extensible Toolkit For Real-Time High-Performance Wideband Spectrum Sensing

This document describes the design process of a software toolkit to perform high-performance wideband spectrum sensing. A prominent application of this is Cognitive Radio, a technique that aims to make more efficient use of the available radio spectrum. An extensive theoretical analysis will be performed. Various non-uniform sampling techniques...

Beschrijving en vergelijking van drie berekeningsmethodes, te weten de methodes van Jacobaeus, mej. Jung en Bininda/Wendt, voor het spreekwegnetwerk van een telefooncentrale volgens het schalmsysteem

De drie berekeningsmethodes worden beschreven en vergeleken met name zijn essentiële verschillen tussen deze methodes vermeld. Eveneens zijn omstandigheden aangewezen waarbij tussen de drie berekeningsmethodes duidelijke verschillen optreden in theoretische juistheid en eenvoud en snelheid van uitvoering van de berekeningen.
