Vogels, Marlein (author)Purpose: In percutaneous renal ablation (PRA), reaching the target accurately is challenging due to target motion and limited real-time visualization of the target, requiring a suitable navigation strategy. In the context of this thesis research, skin markers are used in combination with an the Azurion C-arm system (Philips Healthcare, Best, The...master thesis 2023

Marinissen, Annemar (author)Patient motion during an MR scan is still a problem in the medical field. It results in artefacts and reduces image quality which can lead to wrong patient outcomes. A patient moves due to the long scanning times, discomfort, and restlessness. Motion correction techniques are developed to prevent or compensate for the movements. Prospective...master thesis 2023

van Kouwen, Niels C. (author), Ton, A.M. (author), Vos, S.E. (author), Vijverberg, Thomas (author), Reniers, A.J.H.M. (author), Aarninkhof, S.G.J. (author)Many sand spits are morphodynamically complex landforms, that are either analysed with complex and expensive computational models or at a conceptual level. Therefore, most case studies on spits in different environments are descriptive. A novel method based on the use of polar coordinates was devised to quantitatively analyse spit...journal article 2023

Peters, J.A. (author), Djanashvili, K. (author)In this review, the chemical mechanisms behind the interactions between boronic acids and N-acetylneuraminic acids, which have been widely utilized in biomedicine in recent decades, will be examined. It will also be highlighted that the affinity of boronic acids for N-acetylneuraminic acids is dependent on pH and is complementary to their...review 2023

(author), van Vugt, Marieke (author), Wijnen, Frank (author), Palaniyappan, Lena (author)This workshop summary on natural language processing (NLP) markers for psychosis and other psychiatric disorders presents some of the clinical and research issues that NLP markers might address and some of the activities needed to move in that direction. We propose that the optimal development of NLP markers would occur in the context of...journal article 2023

van Kouwen, Niels (author)Many sand spits are morphodynamically complex cases that are hard to quantify. Therefore, most case studies on sand spits in a specific type of environment, are descriptive or even non-existent. As is the case for spits in low-energy lake environments, like the two spits at the Marker Wadden islands. Because quantification is necessary for spits...master thesis 2022

Vledder, Amária (author)Delayed healing or non-union of bone fractures are still clinically and economically relevant problems. Bone healing includes pro- and anti-inflammatory phases, which proved crucial for successful healing. Being able to modulate these inflammatory responses could potentially promote bone fracture healing. Dendritic cells play important roles in...master thesis 2022

Maat, Alex (author)Augmented Reality (AR) tracking for mobile devices is not realiable in environments where large virtual content, such as an entire virtual building, is to be displayed to the user. This paper presents a study on how multiple on-site markers can be used to better align the virtual scene to the real-world environment to improve large-scale AR...bachelor thesis 2022

Lin, Giovanni (author)Augmented Reality has the potential to expand our interaction with our surrounding environment. A potential solution to improve this interactability is Visible Light Communication through blinking Light Emitting Diodes (LEDs). Data is encoded and then transmitted by blinking the LED, a smart-phone camera is then pointed at the LED to decode the...bachelor thesis 2022

Kools, Pieter (author)To design more efficient sailing boat sails and to analyze the efficiency of a sail trim on the water, it is very helpful to have the ability to obtain a digital copy of real-life sail configurations. As a step towards obtaining such digital copies, the Sailing Innovation Centre in collaboration with GeoDelta has created point cloud measurements...master thesis 2022

Gevers, Imke (author)Background: Radiostereometric analysis (RSA) is a technique to assess early migration, which has a predictive value for early failure of unicompartmental knee arthroplasty (UKA). To successfully analyze the RSA images it is important to have a sufficient amount of visiblemarkers with an acceptable three-dimensional distribution.<br/>Objective:...master thesis 2022

Thabit, Abdullah (author), Niessen, W.J. (author), Wolvius, Eppo B. (author), van Walsum, T. (author)Optical-based navigation systems are widely used in surgical interventions. However, despite their great utility and accuracy, they are expensive and require time and effort to setup for surgeries. Moreover, traditional navigation systems use 2D screens to display instrument positions causing the surgeons to look away from the operative field...conference paper 2022

Uchida, Thomas K. (author), Seth, A. (author)Estimating kinematics from optical motion capture with skin-mounted markers, referred to as an inverse kinematic (IK) calculation, is the most common experimental technique in human motion analysis. Kinematics are often used to diagnose movement disorders and plan treatment strategies. In many such applications, small differences in joint...journal article 2022

Rijlaarsdam, D.D.W. (author), Zwick, Martin (author), Kuiper, J.M. (author)Pose estimation in robotics is often achieved using images from known and purposefully applied markers or fiducials taken by a monocular camera. This low-cost system architecture can provide accurate and precise pose estimation measurements. However, to prevent the restriction of robotic movement and occlusions of features, the fiducial markers...journal article 2022

(author)OBJECTIVE: Folate receptor beta (FR-β) has been used as a clinical marker and target in multiple inflammatory diseases, including osteoarthritis (OA) and rheumatoid arthritis (RA). However, the conditions under which FR-β+ macrophages arise remain unclear and could be affected by corticosteroids. Therefore, we studied FR-β expression in vitro...journal article 2022

Wellen, Fleur (author)The Noordstrand of the Marker Wadden has been subject to much more erosion than expected. From our current understanding of this low-energy system we cannot explain what has been the cause of this. The goal of this thesis is to create a better understanding of the different processes responsible for the development of this non-equilibrium beach...master thesis 2021

Rijlaarsdam, David (author)To mitigate the growth of space debris, it is vital that Active Debris Removal (ADR) is performed in the near future. Since ADR will require robust relative navigation, future spacecraft should be marked with fiducial markers that are robustly extracted from an image taken by a chaser spacecraft. To prevent the restriction of robotic movement...master thesis 2021

Maciel, Luiz (author), Marroquim, Ricardo (author), Vieira, Marcelo (author), Ribeiro, Kevyn (author), Alho, Alexandre (author)We present a method to recover the 3D flying shape of a sail using passive markers. In the navigation and naval architecture domain, retrieving the sail shape may be of immense value to confirm or contest simulation results, and to aid the design of new optimal sails. Our acquisition setup is very simple and low-cost, as it is only necessary...journal article 2021
