Dutruel, Benjamin (author)The startup Rocket Factory Augsburg (RFA) is developing the RFA ONE orbital launch vehicle. A significant hurdle for its closed-loop guidance is the need to fully deplete the third stage for insertion during the first flight, which results in lengthy burn-arcs and complexity not managed properly by traditional guidance algorithms. Additionally,...master thesis 2023

Li, M. (author), Jiang, X. (author), Carroll, James (author), Negenborn, R.R. (author)The determination of maintenance strategies is subject to complexity and uncertainty arising from variable offshore wind farm states and inaccuracies in model parameters. The most common method in the existing studies is to adopt an open-loop approach to optimize a maintenance strategy. However, this approach lacks the ability to capture...journal article 2023

Buitenhuis, R. N. (author), Saikumar, N. (author), Hassan HosseinNia, S. (author)The ever-increasing industry desire for improved performance makes linear controller design run into fundamental limitations. Nonlinear control methods such as Reset Control (RC) are needed to overcome these. RC is a promising candidate since, unlike other nonlinear methods, it easily integrates into the industry-preferred PID design...journal article 2023

Kerssemakers, Daan (author)To accelerate the growth of offshore wind power, its Levelised Cost Of Energy (LCOE) must be reduced. A means of reducing the LCOE of offshore wind power is by mitigating the adverse wake effect by employing Wind Farm Control (WFC) for power maximization. A recent WFC technology is the helix approach, which uses Individual Pitch Control (IPC) to...master thesis 2022

Kragt, Wouter (author)To be able to cope with the demands of next generation radar applications, a bandwidth of 400MHz is required. The SAR assisted CT ∆Σ ADC provides an energy efficient ADC, but needs improvements to cope with the bandwidth enlargement. This thesis examines the front end components and thus initially focuses on resolving the issues in the front end...master thesis 2022

Kerssemakers, Tom (author)With over 75,000 attributed deaths in 2020, opioid overdose is now the leading cause of death amongst Americans under the age of 50. With record-breaking increases in fatalities for the past 10 years, fentanyl in particular has many experts worried about the future of the opioid epidemic. To reverse opioid overdose there exists a drug called...master thesis 2022

Liu, Di (author), Besselink, Bart (author), Baldi, S. (author), Yu, Wenwu (author), Trentelman, Harry L. (author)Despite the progress in the field of longitudinal formations of automated vehicles, only recently an interpretation of longitudinal platooning has been given in the framework of disturbance decoupling, i.e. the problem of making a controlled output independent of a disturbance. The appealing feature of this interpretation is that the...journal article 2022

(author)Tremor is thought to be an effect of oscillatory activity within the sensorimotor network. To date, the underlying pathological brain networks are not fully understood. Disentangling tremor activity from voluntary motor output and sensorimotor feedback systems is challenging. To better understand the intrinsic sensorimotor fingerprint...journal article 2022

Verzijl, Hubald (author)<i>Neuropathic pain</i> (NP) affects approximately seven to ten percent of the general population. Seventeen percent of NP patients scored their life as “worse than death”. A myriad of causes may underlie NP, such as stroke or spinal cord injury. Also, damage or disease of the <i>peripheral nervous system</i> (PNS) may result in NP. One of the...master thesis 2021

Li, Yongzhe (author), Li, Xinlei (author), Zhang, Guangjun (author), Horvath, I. (author), Han, Qinglin (author)The deposition process of wire and arc additive manufacturing (WAAM) is usually planned based on a bead geometry model (BGM), which represents the relationship between bead geometries (e.g. width, height) and required deposition parameters. However, the actual deposition situation may deviate from the one in which the BGM is built, such as...journal article 2021
