  1. Low temperature deposition and characterisation of high quality nanocrystalline diamond films for the fabrication of highly sensitive pressure sensing membranes

    Drijkoningen, Sien

  2. Conjugated polymer nanoparticles for photovoltaic and bio-imaging applications

    D'Olieslaeger, Lien
    Geconjugeerde polymeren zijn door hun buitengewone opto-elektronische eigenschappen uitermate interessant voor vele toepassingen. Ze zijn meestal vrij hydrofoob en daarom dienen organische solventen gebruikt te worden om ze te kunnen verwerken. Het gebruik van grote hoeveelheden van deze oplosmiddelen heeft echter een dramatische impact op het milieu en de menselijke gezondheid. Daarom bestuderen onderzoekers momenteel ‘groenere’ alternatieven voor de verwerking van geconjugeerde polymeren. Een veelbelovende aanpak hierbij is het gebruik van geconjugeerde polymere nanodeeltjes die aangemaakt worden als watergebaseerde dispersies. Een aantal onderzoeksgroepen hebben reeds gerapporteerd over de synthese van dergelijke nanodeeltjes. Toch is er over nanodeeltjes gemaakt van zogenaamde...

  13. Statistical evaluation methodology for surrogate endpoints in clinical studies

    Van der Elst, Wim
    In klinische studies is het niet altijd mogelijk om de meest relevante indicator van behandelingssucces te gebruiken. Zo bestaat bijvoorbeeld de mogelijkheid dat het klinische eindpunt pas lange tijd na de start van de studie kan worden gemeten (bvb. overlevingstijd in oncologie). Gebruik van dit klinisch eindpunt zou dan ook impliceren dat de nieuwe behandeling pas na een lange tijd kan worden geëvalueerd. Als zulke situatie zich voordoet kan het interessant zijn om het klinisch eindpunt te vervangen door een zgn. ‘surrogaat eindpunt’. Dit is een eindpunt dat sneller kan worden gemeten dan het klinisch eindpunt, en dat toelaat om...

  14. Physiological responses of sunflower Clearfield hybrids to the herbicide imazamox

    Balabanova-Ivanovska, Dobrinka Anastasova
    Because of the high importance of sunflower as an oilseed crop that is mainly used for human consumption, high yield and quality are very important, especially in the context of an increasing world population. Therefore appropriate and efficient cultivation of sunflower are very important for the agricultural sector. Harmful weed species appear to be the main problem for successful and sustainable cultivation of sunflower, causing considerable yield losses worldwide. Application of herbicides is the most common method for weed control in sunflower cultivation, but its biology and growth features require a continuous exploration for new and more effective tools to...

  15. Representations and Algorithms for Interactive Relighting

    Michiels, Nick
    Classic relighting applications are striving to unite the virtual world and the real world by applying computer graphics algorithms to pixel and image-based descriptions. This has allowed them to apply new virtual lighting conditions on real images as well as inserting virtual objects in real environments under credible lighting conditions. However, state-of-the-art representations for geometry, materials and lighting often limit the capabilities and quality of the simulation of light in relighting applications. Spherical harmonics allow for a fast simulation of light, but can only handle low-frequency lighting effects efficiently. In addition, other relighting applications rely on Haar wavelets; which are...

  16. The role of endophytes and copper nanoparticles in the success or failure of DDE phytoremediation using Cucurbita pepo

    Eevers, Nele
    2,2-bis(p-chlorophenyl)-1,1,1-trichloroethane (DDT) was produced and applied as a pesticide starting in 1939, and was used globally by 1943 (Turusov et al., 2002). In 1974, sufficient evidence was gathered demonstrating that DDT and its metabolites, 2,2-bis(p-chlorophenyl)-1,1-dichloro-ethylene (DDE) and 1,1- dichloro-2,2-bis(p-chlorophenyl)-ethane (DDD), were persistent in the environment and showed bioaccumulation in higher animal species causing for instance egg shell thinning and endocrine disruption as a consequence (Thomas et al., 2008). These findings lead to the ban of the production and use in Belgium. DDE toxicity and recalcitrance are therefore regarded as important environmental problems. The hydrophobic character of DDE causes a strong...

  17. End-User Control over Physical User-Interfaces: From Digital Fabrication to Real-Time Adaptability

    Ramakers, Raf
    Graphical user interfaces are at the core of the majority of computing devices, including WIMP (windows, icons, menus, pointer) interaction styles and touch interactions. The popularity of graphical user interfaces stems from their ability to adapt to a multitude of tasks, such as document editing, messaging, browsing, etc. New tools and technologies also enabled users without a technical background to author these kind of digital interfaces, for example, filters for quick photo editing, interactive profiles on social media, or easy-to-use content management systems. In contrast, physical interfaces are hard to author as they embody electronic input and output sensors directly...

  18. Nonequilibrium Dynamics in an Active Viscoelastic Bath: Particles and Polymers

    Vandebroek, Hans
    In this thesis we investigate the dynamics of various systems that reside in an active viscoelastic bath. What makes these baths particularly interesting is that they are both complex and not in equilibrium. The complexity of the baths is found in their viscoelastic nature that, other than in viscous baths, hinder persistent motion. This characteristic is achieved by memory effects that influence both the friction and the thermal agitation that the bath inflicts on the system. These effects often yield anomalous dynamics, which implies a deviation from normal diffusion. A solely viscoelastic bath obeys the fluctuation-dissipation relation. The system will,...

  19. Advanced relighting algorithms for post-production

    Put, Jeroen
    In this dissertation, a set of algorithms are provided for relighting in a movie post-production environment. Lighting is a crucial factor in how an object appears to an audience. It can be used to hide certain parts of objects or to explicitly reveal them. Often, lighting controls the mood in scenes or conveys subtle emotions. It can occur that a particular scene configuration is not to the liking of a film director at some point in the production phase. Perhaps he would like to add some lighting or remove a disturbing glare that bounces of a chair next to a metallic object....
