Geldof, Freija (author), Dashtbozorg, Behdad (author), Hendriks, B.H.W. (author), Sterenborg, Henricus J.C.M. (author), Ruers, Theo J.M. (author)During oncological surgery, it can be challenging to identify the tumor and establish adequate resection margins. This study proposes a new two-layer approach in which diffuse reflectance spectroscopy (DRS) is used to predict the top layer thickness and classify the layers in two-layered phantom and animal tissue. Using wavelet-based and peak...journal article 2022

Saidmurodov, Saidkomil S. (author), Jacobsen, Stefan (author), Hendriks, M.A.N. (author), Shamsutdinova, Guzel (author)The process of ice melting during abrasive interactions with concrete is essential in a variety of contact phenomena. In this paper, we refer to abrasive tests for different samples of concrete with roughness in the range of 9–35 μm. The experimental conditions were: 1 MPa ice pressure, ambient temperature −10 °C, average sliding velocity 0–0.16...journal article 2022

(author), De With, Peter H.N. (author)Background: Neurosurgical procedures are complex and require years of training and experience. Traditional training on human cadavers is expensive, requires facilities and planning, and raises ethical concerns. Therefore, the use of anthropomorphic phantoms could be an excellent substitute. The aim of the study was to design and develop a...journal article 2022

de Putter, Arjen (author), Hendriks, M.A.N. (author), Rots, J.G. (author), Yang, Y. (author), Engen, Morten (author), van den Bos, Ab A. (author)Nineteen 2D nonlinear finite element analysis (NLFEA) solution strategies were benchmarked against a wide variety of 101 experiments on reinforced concrete beams failing in bending, flexural shear, or shear compression. The relatively high number of solution strategies was motivated by the conviction that choices for the constitutive models,...journal article 2022

Moghaddasi, Hanie (author), Hendriks, R.C. (author), van der Veen, A.J. (author), de Groot, N.M.S. (author), Hunyadi, Borbala (author)Atrial fibrillation (AF) is the most sustained arrhythmia in the heart and also the most common complication developed after cardiac surgery. Due to its progressive nature, timely detection of AF is important. Currently, physicians use a surface electrocardiogram (ECG) for AF diagnosis. However, when the patient develops AF, its various...journal article 2022

Zhang, F. (author), Yang, Y. (author), Fennis, Sonja A.A.M. (author), Hendriks, M.A.N. (author)Acoustic emission (AE) signal parameters can be used to classify the source type in concrete structures. However, signal parameters are influenced by the wave propagation from the source to the receiver, leading to wrong source classification results, especially for monitoring large concrete structures. This paper experimentally evaluates the...journal article 2022

Aydin, B.B. (author), Binici, Baris (author), Hendriks, M.A.N. (author), Tuncay, Kagan (author)Significant infill wall damage in reinforced concrete frame buildings was observed in the past earthquakes. A vast number of numerical approaches have been proposed to estimate the non-linear behavior of infilled frames at different scales. Mesoscale lattice models were successfully used in the past to simulate the behavior of reinforced...journal article 2022

Zhang, F. (author), Yang, Y. (author), Naaktgeboren, N.M. (author), Hendriks, M.A.N. (author)This paper proposes a new damage identification method, namely, the probability density field of acoustic emission (AE) events. This new method provides a different perspective to deal with the uncertainties in the source localization process. We treat the source location as a random variable, and estimate its probability density field based...journal article 2022

(author)Surgical excision is the golden standard for treatment of intestinal tumors. In this surgical procedure, inadequate perfusion of the anastomosis can lead to postoperative complications, such as anastomotic leakages. Imaging photoplethysmography (iPPG) can potentially provide objective and real-time feedback of the perfusion status of tissues....journal article 2022

Wesselius, F.J. (author), van Schie, M.S. (author), de Groot, N.M.S. (author), Hendriks, R.C. (author)Background: An increasing number of wearables are capable of measuring electrocardiograms (ECGs), which may help in early detection of atrial fibrillation (AF). Therefore, many studies focus on automated detection of AF in ECGs. A major obstacle is the required amount of manually labelled data. This study aimed to provide an efficient and...journal article 2022

Kongshaug, Simen Sørgaard (author), Hendriks, M.A.N. (author), Kanstad, Terje (author), Markeset, Gro (author)Alkali–silica reaction (ASR) in concrete causes expansion and degradation of the material, which might give adverse structural consequences. From the structural engineer point view, the greatest concern is if ASR leads to loss of structural integrity. Two natural questions arise when assessing existing concrete structures affected by ASR: (1)...journal article 2022

Jadwiga Osmolska, Magdalena (author), Kanstad, Terje (author), Hendriks, M.A.N. (author), Markeset, Gro (author)Corrosion and shear cracking are frequently observed near supports of pretensioned bridge girders in coastal climates, so non-linear finite element analysis was used to study the effect of corrosion on shear performance in a real case study. Varying degrees of corrosion and various locations (top strands, bottom strands, vertical stirrups and...journal article 2022

(author), Frostell, Arvid (author), Edström, Erik (author), Persson, Oscar (author), Elmi-Terander, Adrian (author)Glial tumors grow diffusely in the brain. Survival is correlated to the extent of tumor removal, but tumor borders are often invisible. Resection beyond the borders as defined by conventional methods may further improve prognosis. In this proof-of-concept study, we evaluate diffuse reflectance spectroscopy (DRS) for discrimination between...journal article 2022

(author)The amount of suspended fines in the southern North Sea strongly depends on their exchange with the sandy seabed. This exchange is governed by resuspension of fines during storms, followed by burial in the week thereafter. Despite its importance for fine sediment dynamics, the burial of fines into a sandy seabed is currently not well...journal article 2022

Roosen, M.A. (author), Yang, Y. (author), van der Veen, C. (author), Schaafsma, Dick G. (author), Hendriks, M.A.N. (author)When the shear resistance of prestressed beams with stirrups is determined with the current Eurocode, no distinction is made between regions with and without flexural cracks. This while it may be expected that a region without flexural cracks will have a higher shear resistance. This is due to the lower longitudinal strains and the narrow...journal article 2022
