Wesselius, F.J. (author), van Schie, M.S. (author), de Groot, N.M.S. (author), Hendriks, R.C. (author)Aims: Automated detection of atrial fibrillation (AF) in continuous rhythm registrations is essential in order to prevent complications and optimize treatment of AF. Many algorithms have been developed to detect AF in surface electrocardiograms (ECGs) during the past few years. The aim of this systematic review is to gain more insight into...review 2021

Azizian Amiri, S. (author), van Berckel, Pieter (author), Dankelman, J. (author), Hendriks, B.H.W. (author)Distinguishing the diseased breast tissue from the healthy tissue is a sorely challenging task for the surgeons during breast conserving surgery (BCS) as both tissues own relatively similar visual and haptic characteristics. It has been shown that diffused reflectance spectroscopy (DRS) has the potential to be used as a real-time tumor margin...conference paper 2021

(author)Establishing adequate resection margins during colorectal cancer surgery is challenging. Currently, in up to 30% of the cases the tumor is not completely removed, which emphasizes the lack of a real-time tissue discrimination tool that can assess resection margins up to multiple millimeters in depth. Therefore, we propose to combine spectral...conference paper 2021

(author), De With, Peter H.N. (author)Neurosurgical training is performed on human cadavers and simulation models, such as VR platforms, which have several drawbacks. Head phantoms could solve most of the issues related to these trainings. The aim of this study was to design a realistic and CT-compatible head phantom, with a specific focus on endo-nasal skull-base surgery and...conference paper 2021

Pari, M. (author), van de Graaf, Anne (author), Hendriks, M.A.N. (author), Rots, J.G. (author)In the finite element modelling of masonry structures, the micro-modelling technique of differentiating the continuum into a linear elastic bulk, and interfaces representing non-linear joints is common. However, this approach of simulating cracking-crushing-shearing failure possibilities in interfaces, typical of damage in masonry, also poses...journal article 2021

Sun, M. (author), de Groot, N.M.S. (author), Hendriks, R.C. (author)Impaired electrical conduction has been shown to play an important role in the development of heart rhythm disorders. Being able to determine the conductivity is important to localize the arrhythmogenic substrate that causes abnormalities in atrial tissue. In this work, we present an algorithm to estimate the conductivity from epicardial...journal article 2021

Geiker, M. R. (author), Hendriks, M.A.N. (author), Elsener, B. (author)In Europe, design for the durability of new reinforced concrete structures is currently based on a prescriptive approach. The design, execution (construction) and planned maintenance of a concrete structure have to lead to the intended level of safety and serviceability throughout its entire service life. This requires numeric models based on...journal article 2021

Kolling, B. (author), Abdi, Bahareh (author), Groot, N.M.S. de (author), Hendriks, R.C. (author)Atrial electrograms are often used to gain understanding on the development of atrial fibrillation (AF). Using such electrograms, cardiologists can reconstruct how the depolarization wave-front propagates across the atrium. Knowing the exact moment at which the depolarization wavefront in the tissue reaches each electrode is an important aspect...conference paper 2020

Kotti, Sofia Eirini (author), Heusdens, R. (author), Hendriks, R.C. (author)The use of wireless acoustic sensor networks (WASNs) has received increased attention over the last decade. The advantages of WASNs over stand-alone multi-microphone devices are that the microphone array is not anymore limited by the dimensions of a single device, and that microphones can be placed at arbitrary locations. One of the...conference paper 2020

Hendriks, Céline (author)In 2017 the island Sint Maarten was hit by hurricane Irma. Approximately ninety-one per cent of the build environment was damaged. This made the existing housing shortage, caused by a growing population, even more significant. Now, three years later, the residential area of Philipsburg is mostly deserted. With the departure of its residents, the...master thesis 2020

Sun, M. (author), Isufi, E. (author), de Groot, N.M.S. (author), Hendriks, R.C. (author)Atrial fibrillation is a clinical arrhythmia with multifactorial mechanisms still unresolved. Time-frequency analysis of epicardial electrograms has been investigated to study atrial fibrillation. However, deeper understanding can be achieved by incorporating the spatial dimension. Unfortunately, the physical models describing the spatial...journal article 2020
