Wani, F.M. (author), Shipurkar, U. (author), Dong, J. (author), Polinder, H. (author)This paper compares active and passive cooling systems in tidal turbine power electronic converters. The comparison is based on the lifetime of the IGBT (insulated gate bipolar transistor) power modules, calculated from the accumulated fatigue due to thermal cycling. The lifetime analysis accounts for the influence of site conditions, namely...journal article 2021

Peyghami, S. (author), Blaabjerg, Frede (author), Palensky, P. (author)This article aims to incorporate the reliability model of power electronic converters into power system reliability analysis. The converter reliability has widely been explored in device- and converter-levels according to physics of failure analysis. However, optimal decision-making for design, planning, operation, and maintenance of power...journal article 2021

Sattari, R. (author), van Zeijl, H.W. (author), Zhang, Kouchi (author)This paper focuses on the design and fabrication of a new programmable thermal test chip as a flexible and cost-effective solution for simplification of characterization/prototyping of new packages. The cell-based design format makes the chip fit into any modular array configuration. One unit cell is as small as 4x4 mm2, including 6 individually...conference paper 2021

Akgün, O.C. (author), Nanbakhsh, K. (author), Giagka, Vasiliki (author), Serdijn, W.A. (author)For mm-sized implants incorporating silicon integrated circuits, ensuring lifetime operation of the chip within the corrosive environment of the body still remains a critical challenge. For the chip's packaging, various polymeric and thin ceramic coatings have been reported, demonstrating high biocompatibility and barrier properties. Yet, for...journal article 2020

van den Boomen, M. (author)Ageing infrastructures and shortage of financing induce the need for optimising public infrastructure replacements. From an economic perspective, classical net present value comparison is traditionally the method of choice to decide on investments and replacements. The current research observes that typical infrastructure related features make...doctoral thesis 2020

Girard, Patrick (author), Cheng, Yuanqing (author), Virazel, Arnaud (author), Zhao, Weisheng (author), Bishnoi, R.K. (author), Tahoori, Mehdi B. (author)Memories occupy most of the silicon area in nowadays' system-on-chips and contribute to a significant part of system power consumption. Though widely used, nonvolatile Flash memories still suffer from several drawbacks. Magnetic random access memories (MRAMs) have the potential to mitigate most of the Flash shortcomings. Moreover, it is...review 2020

van der Krogt, M.G. (author), Klerk, W.J. (author), Kanning, W. (author), Schweckendiek, T. (author), Kok, M. (author)Spatial variability and limited measurements often result in low reliability estimates of geotechnical failure modes of dikes (i.e., earthen flood defences). Required dike reinforcements are usually not executed within a few years after inception, which enables efforts to improve reliability estimates by reducing uncertainty. Often decision...journal article 2020

Peyghami, S. (author), Palensky, P. (author), Blaabjerg, Frede (author)Renewable energy resources are becoming the dominating element in power systems. Along with de-carbonization, they transform power systems into a more distributed, autonomous, bottom-up style one. We speak of Smart Grid and Microgrid when distributed energy resources take over. While being a means to improve technical and financial efficiency,...journal article 2020

Roubos, A.A. (author), Schweckendiek, T. (author), Brinkgreve, R.B.J. (author), Steenbergen, R. D. J. M. (author), Jonkman, Sebastiaan N. (author)While reliability methods have already been widely adopted in civil engineering, the efficiency and robustness of finite element-based reliability assessments of quay walls are still fairly low. In this paper, the reliability indices of structural and geotechnical failure modes of two real-life quay walls are determined by coupling...journal article 2020

Shekhar, A. (author), Soeiro, Thiago B. (author), Ramirez Elizondo, L.M. (author), Bauer, P. (author)Hybrid ac-dc distribution systems with multiple parallel operating ac and dc links are being developed to maximize system capacity during (n-1) contingencies. This paper shows that offline reconfigurability between such ac and dc links post-fault clearance allows an additional design flexibility of reducing the required substation converter...journal article 2020

Kucharski, R.M. (author), Fielbaum, Andres (author), Alonso-Mora, J. (author), Cats, O. (author)Sharing rides in on-demand systems allow passengers to reduce their fares and service providers to increase revenue, though at the cost of adding uncertainty to the system. Notably, the uncertainty of ride-pooling systems stems not only from travel times but also from unique features of sharing, such as the dependency on other passengers'...journal article 2020

Peyghami, S. (author), Palensky, P. (author), Fotuhi-Firuzabad, Mahmoud (author), Blaabjerg, Frede (author)Power electronic converters will serve as the fundamental components of modern power systems. However, they may suffer from poorer reliability if not properly designed, consequently affecting the overall performance of power systems. Accordingly, the converter reliability should be taken into account in design and planning of Power Electronic...journal article 2020

Pol, J.C. (author), van Beek, Vera (author), Kanning, W. (author), Jonkman, Sebastiaan N. (author)Backward erosion piping is an important failure mode of dikes and dams. The time required for the backward erosion process to result in dike failure is expected to be an important factor in the safety of dikes. This holds especially in coastal and estuarine areas which are dominated by storm surge, and pipes may not fully develop during a storm....conference paper 2019
