Maus, Sönke (author), Bahafid, Sara (author), Hendriks, M.A.N. (author), Jacobsen, Stefan (author), Geiker, Mette Rica (author)Frost salt scaling of concrete is related to cyclic freezing and melting of a few millimeter thick deicer solution on the surface of the concrete. It is almost absent when pure water is freezing and reaches a maximum at a so-called pessimum concentration that for NaCl is around 3%. Different mechanisms have been suggested to explain this...journal article 2023

Bresser, D. (author), Rots, J.G. (author), Hendriks, M.A.N. (author), Pari, M. (author)Sequentially Linear Analysis (SLA), an event-by-event solution strategy in which a sequence of scaled linear analyses with decreasing secant stiffness is performed, representing local damage increments; is a robust alternative to nonlinear finite element analysis of quasi-brittle structures. Since it is based on a fixed smeared crack...journal article 2023

Xu, Jie (author), Hendriks, M.A.N. (author), Rots, J.G. (author), Tsouvalas, A. (author)Due to the accompanying severe consequences of explosions, the blast puts a great threat to public security. Nonlinear finite element analysis is a possible method for civil engineers to check the integrity of the structures under blast loading without underestimating the limit of the structures. However, different choices of element types...conference paper 2023

Ibrahim, M.S. (author), Poliotti, M. (author), Yang, Y. (author), Hendriks, M.A.N. (author)Typically precast girders are designed and utilized as simple supported members. Alternatively, the precast girders can be made continuous at the intermediate support using cast-in-place concrete topping. Once the girders are made continuous, time-dependent restraint moments will occur. The magnitude of the restraint moment is mainly affected by...conference paper 2023

Li, C. (author), Hendriks, R.C. (author)Estimating the parameters that describe the acoustic scene is very important for many microphone array applications. For example, consider the power spectral densities (PSDs) or relative acoustic transfer functions (RTFs) that are required when estimating a particular sound source using multi-microphone noise reduction. State-of-the-art...conference paper 2023

(author)The most important prognostic factor for the survival of advanced-stage epithelial ovarian cancer (EOC) is the completeness of cytoreductive surgery (CRS). Therefore, an intraoperative technique to detect microscopic tumors would be of great value.

(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

Riemens, E.H.J. (author), Martinez-Nuevo, Pablo (author), Martinez, Jorge (author), Møller, Martin Bo (author), Hendriks, R.C. (author)Loudspeakers are usually placed in an environment unknown to the loudspeaker designers. Having knowledge on the room acoustic properties, e.g., the location of acoustic reflectors, allows to better reproduce the sound field as intended. Current state-of-the-art methods for room boundary detection using microphone measurements typically focus on...conference paper 2022

Moghaddasi, Hanie (author), Hunyadi, Borbala (author), van der Veen, A.J. (author), de Groot, N.M.S. (author), Hendriks, R.C. (author)Atrial Fibrillation (AF) is the most sustained arrhythmia in the heart. On the surface electrocardiogram (ECG), AF is characterised by the irregular RR intervals and by fibrillatory waves or the absence of a P wave. Since AF is a progressive disease, timely and correct detection is crucial for AF treatment. Detailed insight into the areas of...conference paper 2022
