Lang, Matti (author)To offer engaging neurorehabilitation training to stroke patients, robotic exoskeletons have emerged as a beneficial tool to train motor tasks. However, in robotic therapy, the therapists are often limited in how they can interact with the patients. The training programs with exoskeletons are often standardized, not allowing the therapist to...master thesis 2024

Cheizoo, Bas (author)The speed and precision required in the precision motion industry is an ever-growing challenge. Linear control offers intuitive frequency-domain controller design methods that are based on a frequency response function (FRF) of the plant, which is obtained solely from measurement data. Unsurprisingly, linear controllers account for over 90% of...master thesis 2024

Maan, Gijsbert (author)Haptic bilateral teleoperation is a concept where operators can feel, interact with and manipulate objects in a remote environment. The latency, often introduced by a network over a long distance, on force feedback poses a problem when trying to interact with objects. Model mediated teleoperation tries to mitigate this latency, but introduces...master thesis 2024

Rietveld, Maurits (author)Train drivers are challenged to stay alert during train driving, for a big part due to the limited amount of tasks, and monotony of tasks. Driver condition monitoring (DCM) is a technology that involves measuring the driver’s alertness state in real-time, in which use of eye-based measurements is considered. Since DCM’s are upcoming in car and...master thesis 2024

Lee, Y. (author)E-learning has shifted the traditional learning paradigms in higher education, offering more flexible, ubiquitous, and personalized learning experiences. The previous years COVID-19 pandemic required a re-calibration of education to accommodate virtual learning environments from the traditional classroom-based education. Widespread learning...doctoral thesis 2024

Ravenberg, Jevon (author)In this work, we propose a method of processing patient input on discomfort level during robot shoulder physiotherapy into discomfort maps. These maps represent the patient's discomfort distribution throughout the range of motion of the shoulder, interpretable by both physiotherapists and robots. This method consists of three parts: the patient...master thesis 2024

Schoon, Daam (author)To gain more insight into the performance of state-of-the-art Static Output Feedback (SOF) controller synthesis methods for H∞-control, quantitative comparisons are made between Lyapunov methods and well-known established non-smooth optimization methods, i.e. Hinfstruct and HIFOO. Three methods were deemed to be the most promising to compete and...master thesis 2024

Atmaca, D. (author), Pontani, Mauro (author)This research describes a near-optimal feedback guidance, based on nonlinear orbit control, for low-thrust Earth orbit transfers. Lyapunov stability theory leads to proving that although several equilibria exist, only the desired operational conditions are associated with a stable equilibrium. This ensures quasi-global asymptotic convergence...journal article 2024

Gürsan, C. (author), de Gooyert, V. (author), de Bruijne, M.L.C. (author), Raaijmakers, J. (author)District heating systems are considered a feasible heating alternative to replace natural gas to mitigate emissions in cities. However, urban transitions are very complex because energy systems often operate in densely populated areas, which gives rise to all kinds of interdependencies in cities. These interdependencies can result in...journal article 2024

(author), van der Peet, Donald L. (author), Daams, Freek (author), Hardon, S.F. (author), Horeman, T. (author)Collision feedback about instrument and environment interaction is often lacking in robotic surgery training devices. The PoLaRS virtual reality simulator is a newly developed desk trainer that overcomes drawbacks of existing robot trainers for advanced laparoscopy. This study aimed to assess the effect of haptic and visual feedback during...journal article 2024

van Gils, R.H.J. (author), Kornelisse, R. F. (author), Dankelman, J. (author), Helder, O. K. (author)Background: Compliance with the recommended 30 s drying time of alcohol-based hand rub (ABHR) is often suboptimal. To increase hand hygiene compliance at a neonatal intensive care unit (NICU), we installed an Incubator Traffic Light (ITL) system which shows ‘green light’ to open incubator doors after the recommended drying time. Aim: To...journal article 2024

Garofano, V. (author), Hepworth, M. (author), Shahin, R. (author), Pang, Y. (author), Negenborn, R.R. (author)In this study, we investigated autonomous vessel obstacle avoidance using advanced techniques within the Guidance, Navigation, and Control (GNC) framework. We propose a Mixed Integer Linear Programming (MILP) based Guidance system for robust path planning avoiding static and dynamic obstacles. For Navigation, we suggest a multi-modal neural...journal article 2024

A linear matrix inequality approach to optimal reset control design for a class of nonlinear systemsShahbazzadeh, Majid (author), Sadati, S. Jalil (author), Hassan HosseinNia, S. (author)In this article, the problem of the optimal reset control design for Lipschitz nonlinear systems is addressed. The reset controller includes a base linear controller and a reset law that enforces resets to the controller states. The reset law design is strongly dependent on the appropriate design of the base controller. For this reason, in...journal article 2024
