Cavallo, Gaia (author), Schouten, A.C. (author), Lataire, John (author)Human joint impedance is a fundamental property of the neuromuscular system and describes the mechanical behavior of a joint. The identification of the lower limbs' joints impedance during locomotion is a key element to improve the design and control of active prostheses, orthoses, and exoskeletons. Joint impedance changes during locomotion...conference paper 2020

Schouten, D.G.M. (author), Massink, Pim (author), Donker, Stella F. (author), Neerincx, M.A. (author)In this study, we attempt to specify the cognitive support behavior of a previously designed embodied conversational agent coach that provides learning support to low-literates. Three knowledge gaps are identified in the existing work: an incomplete specification of the behaviors that make up ‘support,’ an incomplete specification of how this...journal article 2020

Schouten, Nina (author)This graduation project explores how the concept of problem sustaining interaction (PSI) patterns in mental development in adolescence can be used for design. In contrast to the currently used Diagnostic and Statistical Manual of Mental Disorders (DSM), which describes psychiatric disorders from only a psychological perspective, the concept of...master thesis 2019

Solis Escalante, T. (author), van der Cruijsen, Joris (author), de Kam, Digna (author), van Kordelaar, J. (author), Weerdesteyn, Vivian (author), Schouten, A.C. (author)The contributions of the cerebral cortex to human balance control are clearly demonstrated by the profound impact of cortical lesions on the ability to maintain standing balance. The cerebral cortex is thought to regulate subcortical postural centers to maintain upright balance and posture under varying environmental conditions and task...journal article 2019

van Dijk, J.P.G. (author), Kawakami, E. (author), Schouten, R.N. (author), Veldhorst, M. (author), Vandersypen, L.M.K. (author), Babaie, M. (author), Charbon-Iwasaki-Charbon, E. (author), Sebastiano, F. (author)Quantum processors rely on classical electronic controllers to manipulate and read out the state of quantum bits (qubits). As the performance of the quantum processor improves, nonidealities in the classical controller can become the performance bottleneck for the whole quantum computer. To prevent such limitation, this paper presents a...journal article 2019

Schouten, T.D. (author), Keetels, G.H. (author), van Rhee, C. (author)In dredging applications, deep sea mining and land reclamation projects typically large amounts of sediments are transported through pipes in the form of hyper concentrated (40% sediment or more) sediment-water mixtures or slurry. These slurries can flow at three different regimes. 1: fully suspended (homogeneous and stratified) 2: partially...conference paper 2019

Schut, I.M. (author), Pasma, J.H. (author), De Veij Mestdagh, J.C. (author), van der Kooij, H. (author), Schouten, A.C. (author)To unravel the underlying mechanisms of human balance control, system identification techniques are applied in combination with dedicated perturbations, like support surface translations. However, it remains unclear what the optimal amplitude and number of repetitions of the perturbation signal are. In this study we investigated the effect of...journal article 2019

Cop, Christopher P. (author), Durandau, Guillaume (author), Esteban, Alejandro Moya (author), Van 'T Veld, Ronald C. (author), Schouten, A.C. (author), Sartori, Massimo (author)Joint stiffness estimation under dynamic conditions still remains a challenge. Current stiffness estimation methods often rely on the external perturbation of the joint. In this study, a novel 'perturbation-free' stiffness estimation method via electromyography (EMG)-driven musculoskeletal modeling was validated for the first time against...conference paper 2019

Esteban, Alejandro Moya (author), Van 'T Veld, Ronald C. (author), Cop, Christopher P. (author), Durandau, Guillaume (author), Sartori, Massimo (author), Schouten, A.C. (author)An important goal in the design of next-generation exoskeletons and limb prostheses is to replicate human limb dynamics. Joint impedance determines the dynamic relation between joint displacement and torque. Joint stiffness is the position-dependent component of joint impedance and is key in postural control and movement. However, the...conference paper 2019

(author)Effective treatment of movement disorders requires thorough understanding of human limb control. Joint dynamics can be assessed using robotic manipulators and system identification. Due to tendon compliance, joint angle and muscle length are not proportional. This study uses plane-wave ultrasound imaging to investigate the dynamic relation...conference paper 2019

(author)Current methods to track the progression and evaluate treatment of muscular dystrophies are scarce. The electromechanical delay (EMD), defined as the time lag from muscle electrical activity to motion onset, has been proposed as a biomarker, but provides only limited insight in the pathophysiol-ogy of muscle function. This work proposes and...conference paper 2019

Sreenivasa, Manish (author), Valero-Cuevas, Francisco J. (author), Tresch, Matthew (author), Nakamura, Yoshihiko (author), Schouten, A.C. (author), Sartori, Massimo (author)The motivation behind this research topic was to cut across conventional boundaries that separate movement neuroscience, biomechanics, and robotics. The aim was to underscore that brain and body collaborate to produce behavior in biological organisms. While this is a simple idea, compartmentalization in education and science has often...contribution to periodical 2019

(author), Heida, Tijtske (author)There is no objective gold standard to detect tremors. This concerns not only the choice of the algorithm and sensors, but methods are often designed to detect tremors in one specific group of patients during the performance of a specific task. Therefore, the aim of this study is twofold. First, an objective quantitative method to detect...journal article 2019

Schouten, Sophie (author)The FRISC is a high speed craft of the Netherlands Navy which came into use in 2012. Because these vessels sail with speeds up to 45 knots in inshore waters, a large amount of focus and accurate path following is needed for safe navigation, and due to large accelerations, there is a high level of physical strain. These two factors cause a high ...master thesis 2018
