    (2015-01-01) Developing an image recognition system
    R. Deluster
    The research to robotic fish at the Rijksuniversiteit Groningen has been put on the back burner since 2011. The group of Discrete Technology & Production Automation likes to breathe new life into the development of the robotic fish starting with this Integration Project. The people that will get involved exist mainly out of students Industrial Engineering & Management and PhD candidates. The robotic fish swim in a pool that is situated in the DTPA-lab of the Nijenborgh 4 at the Zernike campus. T....................
    (2015-01-01) The maximum number of ordinary double points on a surface
    Broek, A.W. van den
    In this thesis the maximum number of ordinary double points on an algebraic surface in complex three-space is investigated. For lower degree surfaces a proof of this maximum number can be given; for higher degree surfaces various examples of surfaces with many ordinary double points are discussed.
    (2015-01-01) A computational fluid dynamics analysis on air bearing designs
    Tan, I.W.
    This report treats the results of a research project on simulating the air flow in aerostatic thrust air bearings with the Open Source Computational Fluid Dynamics (CFD) software package OpenFOAM. The type of air bearing considered in this research is a simple type circular bearing with eight orifices that are equally distributed over a concentric circle. In this report we first present some background information on air bearings, treat the fluid dynamics that is involved and consider the previo....................

    (2015-01-01) Dealing with the cochlear implant related artefact in electroencephalographic research
    Sismono, F.M.
    The cochlear implant (CI) related artefact remains a problem researchers are faced with nowadays when analysing the electroencephalographic (EEG) data of subjects implanted with a CI. The CI related artefact can change when different stimuli are used in an experiment, and can even vary a great deal across participants in the same experiment due to different settings on their devices. This makes it very difficult for EEG researchers to reliably identify and remove the artefact from their data, pr....................
    (2015-01-01) Investigation of the effects of Denial-of-Service in wireless control networks
    Zondervan, B
    Nowadays technology is inseparable from our lives. Daily we are dependent on computers, airplanes, power plants and other technological inventions. Due the exponentially grow of technology the last decennia the possibilities in the IT world are getting endless. Companies are getting more and more dependent on their IT infrastructure. Therefore causing also more risks that can lead to failure. One of the most common risks in control networks are Denial of Service. The aim for this project is to i....................
    (2015-01-01) Understanding the dynamics of wind-driven ocean circulation
    Ledoux, R.M.
    This thesis describes several simple models of ocean flows, such as the Stommel model and the Munk model. Some physical and mathematical background is given on the concepts and equations of fluid dynamics, of which the Navier-Stokes equations are of biggest importance. These equations will be adapted to describe flows in a rotating spherical coordinate system that is applicable to large-scale flows on planet Earth and other planets. In order to make the models of interest analytically solvable,....................

    (2015-01-01) De Rolstoeltas
    Hols, E.W.J.
    Vandaag de dag kunnen rolstoelpatiënten met niet aangeboren hersenletsel (NAH) in het revalidatiecentrum Beatrixoord niet bij hun eigendommen die achterop hun rolstoel hangen. Het probleem dat ontstaat uit het feit dat rolstoelpatiënten niet bij hun eigendommen kunnen is dat ze hier geen regie meer over hebben. Het streven naar psychisch herstel speelt hierbij vooral een rol. Wanneer een rolstoelgebruiker controle heeft over zijn of haar eigendommen dan zal dit een gunstig effect hebben op de ....................

    (2015-01-01) Effects of Feedback on Human Performance in Negotiation with a Metacognitive ACT-R Agent
    Renkema, T.R.S.
    In this study, an experiment was conducted in which human subjects played a mixed-motive negotiation game, called Game of Nines, against a metacognitive ACT-R agent. In this game, two players had to divide up 9 points between them. The goal for both players was to get as many points as possible in order to get a higher score. The aim of this study was to examine whether participants' performance on Game of Nines could be enhanced as a result of receiving feedback. This feedback consisted of the ....................
    (2015-01-01) Identity-based encryption using supersingular curves with the Weil pairing
    Mak, R.W.
    In this paper we examine identity based encryption using the Weil pairing for supersingular elliptic curves over finite fields F_p with p suitable, large, primes. We examine a specific algorithm suggested in the textbook by Lawrence C. Washington (2008) and describe why and how it works. We show an implementation of this algorithm in Magma. Finally, we show that it is possible to perform this algorithm for different elliptic curves and offer examples of such curves.

    (2015-01-01) Commercialization of mesoporous USY zeolite
    Zant, L.M.
    Zeolites are catalysts which are mainly used for FCC (fluid catalytic cracking) in an oil refinery. Conventional Ultra Stable Y (USY) zeolite is used in almost all the FCC systems due to its good stability, octane-producing cracking results and better selectivity on coke. This zeolite has a high silica/aluminum rate with high surface areas, being a consequence of ordered micropores of molecular dimensions that enable shape-selective catalytic transformations. The drawback in most industrial reac....................
    (2015-01-01) PageRank algorithm, structure, dependency, improvements and beyond.
    Langbroek, D.A.
    I present an explanation about the PageRank algorithm πT = πTG. Background of G = αH +(αa+(1−α)e)1 net and construction of the matrix H and G while dealing with danglingnodes. I cover the sensitivity of πT to changes in the algorithm and structure of the web. I look at a method to improve upon the PageRank algorithm by changing vT, and implementing a back button for dangling nodes. Moreover I cover the adaptive power method to decrease the number of computations needed per iteration and ....................
