    Designing an ISO 31000 implementation program

    No full text
    The objective of this thesis is to create an blueprint of an ISO 31000 implementation program, different from the ones already on the market. The program must be unique while still respecting the ISO 31000 guidelines. I am an entrepreneur who aims to use the blueprint to develop an commercially interesting program which I can build, manage and/or sell. The theoretical framework is based on ISO 31000 risk management guidelines, ISO 31010 risk management techniques and the Finnish EK framework. I further extended the knowledge base by researching online learning tools and techniques. My aim is to create an new and unique blueprint, which meant starting the design process from zero. The double diamond design process was chosen for this development project. It is split up into four phases, being discovery phase, define phase, develop phase and deliver phase. The last phase has not been applied since that would require an working prototype. The methods used in the various phases are mega trends, an persona empathy map, business model canvas, solution based thinking and the ABC learning design. This development project has shown that there are ways around the traditional ISO 31000 teaching approach. By having users choose between predetermined scopes, I was able to narrow down the information needed to bring the ISO 31000 risk management process, combined with ISO 31010 risk management tools, to an good end. This while still following the recommended structure of ISO 31000, being scope, risk identification, risk analysis, risk evaluation, risk treatment and iteration. Reporting and communication is taken care of trough the use of an template. The template however needs to be developed further. The result is an program existing out of seven modules, being introduction, scope, risk identification, risk analysis, risk evaluation, risk treatment and iteration. Each module has been assigned with one or more learning types, and uses an variation of teaching tools so that the user can choose their preferred learning method. Users who don’t have enough with the information given, or that need better tailored advice can purchase tutoring by the hour for an one on one discussions and advice. The blueprint is ready, the template that should accompany the program needs to be developed further

    Plasma polymerization of fluorine alloyed amorphous carbon coatings

    No full text
    This article reports on the deposition conditions and characterization of plasma polymerized fluorocarbon coatings grown by an inductively coupled radio frequency plasma source, using CH4 and CF4as precursor gases. SiH4, H2, or Ar were further added to the plasma to investigate their influence on the coating properties. The coatings were characterized by x-ray photoelectron spectroscopy to determine the surface and bulk composition and combined with Fourier-transform infrared spectroscopy to reveal the structure of the coatings. The mechanical properties (hardness and Young's modulus) were measured by nano-indentation. The surface energy was obtained by contact angle measurements with two different liquids. By varying the deposition conditions, it was possible to adjust separately the polar and dispersive part of the surface energy. With the appropriate feed gases and process parameters, we were able to deposit coatings with surface energies as low as 14 mN/m. A low polar component of the surface energy corresponds to a high fluorine, CF3and CF2content at the surface of the coatings. The maximum contact angle achieved was 113°. By adding H2 to the plasma, it is possible to minimize the polar component and maximize the dispersive component of the surface energy to obtain a relatively hard (3 GPa) coating with a hydrophobic nature [contact angle (H2O) = 90°]. © 1999 American Vacuum Society.status: publishe

    Physical and tribological properties of a-Si1-xCx : H coatings prepared by r.f. plama-assisted chemical vapour deposition

    a-Si1-xCx : H films deposited by r.f. plasma-assisted chemical vapour deposition were studied as a function of their composition. The friction and wear properties were investigated with the help of a conventional ball-on-disc apparatus. These results are correlated with chemical (Si/C atomic ratio) and structural (Raman and infrared spectroscopy) properties. The friction coefficient in a humid ambient atmosphere changes markedly with the carbon fraction and reaches a value as low as 0.05 for coatings with 70 to 90 at.% C. The carbon-rich films consist of diamond-like carbon with silicon

    Plasma diagnostics of rf discharges used for the deposition of hydrogenated amorphous carbon coatings

    No full text
    The deposition process of amorphous hydrogenated carbon has been studied using optical emission spectroscopy and self-bias measurements. For a given rf power, a transition between two distinct discharge regimes is observed when increasing the pressure. This transition is attributed to different mechanisms by which electrons gain energy in the sheaths and the plasma (α−γ\alpha{-}\gamma discharge transition). Ionic species are shown to play an important role in the formation of hard carbon layers
