Bakker, N.J. (author), Åhman, Hanna Nilsson (author), Aantjes, Kees (author), Barreau, Nicolas (author), Weeber, A.W. (author), Theelen, Mirjam (author)Partial shading of Cu(In,Ga)Se<sub>2</sub> modules can lead to the formation of reverse bias induced wormlike defects. These wormlike defects act as local shunts and permanently decrease module output. A good understanding of the formation and propagation mechanisms of these defects is needed in order to mitigate the negative effects, or to...journal article 2019

Salma, V. (author), Friedl, F. (author), Schmehl, R. (author)Airborne wind energy systems use tethered flying devices to harvest wind energy beyond the height range accessible to tower-based wind turbines. Current commercial prototypes have reached power ratings of up to several hundred kilowatts, and companies are aiming at long-term operation in relevant environments. As consequence, system...journal article 2019

Lefter, M. (author)Within the past half century, Integrated Circuits (ICs) experienced an aggressive, performance driven, technology feature size scaling. As the technology scaled into the deep nanometer range, physical and quantum mechanical effects that were previously irrelevant become influential, or even dominant, resulting in, e.g., not any longer negligible...doctoral thesis 2018

Christodoulou, Antria (author)In this thesis, an image-based method is proposed for solving the relative translation errors of 3D point clouds collected by Mobile Laser Scanning (MLS) techniques. The process of matching 3D point clouds is known as registration. Due to environment-depending limitations of the positioning component of MLS systems, when recording a certain...master thesis 2018

Technical feasibility of a Dutch radioactive waste repository in Boom Clay: Geomechanical validationLi, Y. (author), Vardon, P.J. (author), Hicks, M.A. (author), Hart, Jaap (author), Fokker, Peter A. (author)OPERA-PU-TUD321d<br/>Radioactive substances and ionizing radiation are used in medicine, industry, agriculture, re- search, education and electricity production. This generates radioactive waste. In the Netherlands, this waste is collected, treated and stored by COVRA (Centrale Organisatie Voor Radioactief Afval). After interim storage for a...report 2018

Narayanan, Prasobh (author), Verhagen, W.J.C. (author), Dhanisetty, V.S.V. (author)Airline Maintenance and Engineering (M&E) organizations face accidental damages on their fleet of aircraft as part of daily practice. As this type of damage is stochastic in nature, the approach towards repairing accidental damage is reactive in practice. However, it is possible to predict future long-term (strategic) demand for maintenance...conference paper 2018

Rogova, E.S. (author)Reliability of transport equipment plays a crucial role in providing safety for passengers. Safety systems of transport equipment perform safety functions with assigned safety integrity levels (SIL). If the reliability of a safety system is not sufficient, it has to be improved till the required level. This can be done by improving maintenance,...doctoral thesis 2017

Iannarelli, A. (author), Ghaffarian Niasar, M. (author)Film pre-stretching is a widely adopted solution to improve dielectric strength of the DEA systems. However, to date, long term reliability of this solution has not been investigated. In this work it is explored how the dielectric elastomer lifetime is affected by film pre-stretching. The dielectric loss of soft polydimethylsiloxane (PDMS) films...conference paper 2017

Li, Y. (author)Highway embankments, river dykes and sea dykes usually have a uniform cross-section and extend for a long distance in the third dimension. These long soil structures are generally characterised by spatially varying soil properties, i.e. soil heterogeneity. Slope stability failures of these structures may have significant economic and societal...doctoral thesis 2017
