(author), Dos Santos Martins, L. (author), Dirkse, B. (author), Borregaard, J. (author), Wehner, S.D.C. (author), Hanson, R. (author)We report on the realization of a multi-node quantum network. Using the network, we have demonstrated three protocols; generation of a entangled state shared by all nodes, entanglement swapping and quantum teleportation between non-neighboring nodes.conference paper 2023

Dekker, Bo (author), Schouten, A.C. (author), Scharenborg, O.E. (author)Silent speech interfaces could enable people who lost the ability to use their voice or gestures to communicate with the external world, e.g., through decoding the person’s brain signals when imagining speech. Only a few and small databases exist that allow for the development and training of brain computer interfaces (BCIs) that can decode...conference paper 2023

Geelen, J.E. (author), Branco, Mariana P. (author), Ramsey, Nick F. (author), van der Helm, F.C.T. (author), Mugge, W. (author), Schouten, A.C. (author)Motion capture systems are extensively used to track human movement to study healthy and pathological movements, allowing for objective diagnosis and effective therapy of conditions that affect our motor system. Current motion capture systems typically require marker placements which is cumbersome and can lead to contrived movements.Here, we...conference paper 2021

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, 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

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

Schouten, T.J.E. (author), Hoogreef, M.F.M. (author), Vos, Roelof (author)Four regional turboprop aircraft of different configuration are assessed on their key performance indicators by using an automated conceptual design method. The configurations include two wing-mounted propeller installations (high-wing and low-wing) as well as a fuselagemounted configuration and a tail-mounted configuration. The effect of the...conference paper 2019

Gursel Ozmen, Nurhan (author), van der Helm, F.C.T. (author), Schouten, A.C. (author)The modeling of the dynamic behavior of the human arm is an important issue in robotics, biomedical and medical fields. In this study, it was aimed to construct an inverse dynamics model for the sequential motion of the arm subjected to external force fluctuations using a two degree of freedom manipulator. In experiments with healthy...conference paper 2018

Van'T Veld, Ronald C. (author), Schouten, A.C. (author), van der Kooij, H. (author), Van Asseldonk, Edwin H.F. (author)Biofeedback of online system identification estimates of intrinsic and reflexive joint impedance can be used by able-bodied subjects to voluntarily modulate their reflexive impedance independent of the intrinsic contribution. Similar to EMG-based paradigms, this could potentially be used to reduce muscle hyperreflexia in people with...conference paper 2018

Rahmati, Zahra (author), Behzadipour, Saeed (author), Schouten, A.C. (author), Taghizadeh, Ghorban (author)Studies have shown that balance and mobility in people with Parkinson's disease (PD) can improve through rehabilitation interventions. However, until now no quantitative method investigated how these patients improve their balance control. In this study, a single inverted pendulum model with PID controller was used to describe the improvement...conference paper 2018

van de Ruit, M.L. (author), Lataire, John (author), van der Helm, F.C.T. (author), Mugge, W. (author), Schouten, A.C. (author)During movement, our central nervous system (CNS) takes into account the dynamics of our environment to optimally adapt our joint dynamics. In this study we explored the adaptation of shoulder joint dynamics when a participant interacted with a time-varying virtual environment created by a haptic manipulator. Participants performed a position...conference paper 2018

Schouten, A.C. (author), Mugge, W. (author)The central nervous system controls body functions and initiates actions through an integrated system of multiple feedback loops. System identification can be a valuable tool to assess the system dynamics. The challenge is to assess the functioning of an intact feedback system in vivo, where cause and effect are intermingled. In this paper we...conference paper 2018

Mugge, W. (author), van Hilten, Jacobus J. (author), van der Helm, F.C.T. (author), Schouten, A.C. (author)This paper focuses on the pathophysiology of fixed dystonia (i.e., sustained muscle contractions resulting in abnormal postures) in Complex Regional Pain Syndrome from an engineering point of view. Although the mechanisms are still elusive, the evidence implicating involvement of aberrant muscle force feedback is compelling. A neuromuscular...conference paper 2018
