Denkers, J. (author), Brunner, Marvin (author), van Gool, Louis (author), Vinju, Jurgen J. (author), Zaidman, A.E. (author), Visser, Eelco (author)Flexible printing systems are highly complex systems that consist of printers, that print individual sheets of paper, and finishing equipment, that processes sheets after printing, for example, assembling a book. Integrating finishing equipment with printers involves the development of control software that configures the devices, taking...journal article 2023

Brunner, A.E. (author), Alderliesten, R.C. (author), Pascoe, J.A. (author)Quasi-static or cyclic loading of an artificial starter crack in unidirectionally fibre-reinforced composite test coupons yields fracture mechanics data—the toughness or strain-energy release rate (labelled G)—for characterising delamination initiation and propagation. Thus far, the reproducibility of these tests is typically between 10 and...journal article 2023

Gründemann, Gaby J. (author), van de Giesen, N.C. (author), Brunner, Lukas (author), van der Ent, R.J. (author)Future rainfall extremes are projected to increase with global warming according to theory and climate models, but common (annual) and rare (decennial or centennial) extremes could be affected differently. Here, using 25 models from the Coupled Model Intercomparison Project Phase 6 driven by a range of plausible scenarios of future greenhouse...journal article 2022

van der Sar, S.J. (author), Brunner, Stefan (author), Schaart, D.R. (author)We investigate X-ray photon-counting scintillation detectors with silicon photomultiplier (SiPM) readout. These circumvent some drawbacks of direct-conversion detectors. We measured observed count rate (OCR) versus X-ray tube current for single-pixel detectors consisting of LYSO:Ce and YAP:Ce scintillators coupled to ultrafast SiPMs. For a 30...journal article 2022

van der Sar, S.J. (author), Leibold, D. (author), Brunner, Stefan E. (author), Schaart, D.R. (author)We investigate fast silicon photomultiplier (SiPM)-based scintillation detectors for X-ray photon-counting applications, e.g., photon-counting computed tomography (CT). Such detectors may be an alternative to CdTe/CdZnTe (CZT) and Si detectors, which face challenges related to availability and cost-effective growth of detector-grade material,...conference paper 2022

Visscher, Rosa M.S. (author), Sansgiri, Sailee (author), Freslier, Marie (author), Harlaar, J. (author), Brunner, Reinald (author), Taylor, William R. (author), Singh, Navrag B. (author)Background: To analyse and interpret gait patterns in pathological paediatric populations, accurate determination of the timing of specific gait events (e.g. initial contract – IC, or toe-off – TO) is essential. As currently used clinical identification methods are generally subjective, time-consuming, or limited to steps with force platform...journal article 2021

van der Sar, S.J. (author), Brunner, Stefan E. (author), Schaart, D.R. (author)Purpose: The implementation of photon-counting detectors is widely expected to be the next breakthrough in X-ray computed tomography (CT) instrumentation. A small number of prototype scanners equipped with direct-conversion detectors based on room-temperature semiconductors, such as CdTe and CdZnTe (CZT), are currently installed at medical...journal article 2021

Cavalli, A. (author), Chundru, P. (author), Brunner, Thomas (author), Obernberger, Ingwald (author), Mirabelli, Ilaria (author), Makkus, Robert (author), Aravind, P.V. (author)High temperature biosyngas cleaning is more efficient when the end user operates at elevated temperature, as in biomass gasifier solid oxide fuel cell systems. However, there is not much experience with this technology and low temperature gas cleaning is usually adopted. This paper advances current knowledge by presenting the results from the...journal article 2021

(author), Kozeschnik, Ernst (author), Ecker, Werner (author)This work provides an analysis of X-ray micro computed tomography data of Sn-xBi solders with x = 20, 30, 35, 47, 58 wt.% Bi. The eutectic thickness, fraction of eutectic and primary phase are analyzed. Furthermore, the 3D data is evaluated by means of morphology parameters, such as, shape complexity, flatness, elongation and mean intercept...journal article 2021

Denkers, J. (author), Brunner, Marvin (author), van Gool, Louis (author), Visser, Eelco (author)Within the printing industry, much of the variety in printed applications comes from the variety in finishing. Finishing comprises the processing of sheets of paper after being printed, e.g. to form books. The configuration space of finishers, i.e. all possible configurations given the available features and hardware capabilities, are large....conference paper 2021

Abdul Madhar, S. (author), Brunner, Marc (author), Mor, A. R. (author), Mraz, Petr (author)The discharge over dielectric interfaces popularly known as surface discharge is a very common defect type that is associated with its respective discharge pattern under AC voltages. However, the same designs behave differently under DC voltages leading up to erratic PD behavior. To understand the process of surface discharge an equivalent...conference paper 2021

Brown, J.M.C. (author), Brunner, S. (author), Schaart, D.R. (author)Organ-specific, targeted field-of-view (FoV) positron emission tomography (PET)/magnetic resonance imaging (MRI) inserts are viable solutions for a number of imaging tasks where whole-body PET/MRI systems lack the necessary sensitivity and resolution. To meet the required PET detector performance of these systems, high count-rates and...journal article 2020

Brunner, A.E. (author)In the coming decade, a new generation of extremely large-scale ground-based astronomical telescopes will see first light. It is well known that increasing the size of the telescope aperture is only beneficial if the adaptive optics (AO) system, which compensates for turbulence-induced wavefront aberrations, scales accordingly. For the extreme...doctoral thesis 2018

(author)Typically, a time-of-flight (TOF) PET block detector is built using application-specific integrated circuits (ASICs), since they integrate a high number of channels at a reasonable power consumption and into a small area. However, ASICs’ flexibility is limited and prototyping times are long because a semiconductor fabrication process is required...journal article 2018

Alderliesten, R.C. (author), Brunner, A. J. (author), Pascoe, J.A. (author)Where for metallic materials fatigue fracture testing has contributed significantly to understanding macroscopic and microscopic fatigue failure, the understanding of fatigue fracture in fibre reinforced polymers (FRP) still seems limited. It appears that the research on fatigue in FRPs raises more questions, rather than providing a framework...journal article 2018

(author)To improve gait in children with spastic paresis due to cerebral palsy or hereditary spastic paresis, the semitendinosus muscle is frequently lengthened amongst other medial hamstring muscles by orthopaedic surgery. Side effects on gait due to weakening of the hamstring muscles and overcorrections have been reported. How these side effects...journal article 2018

Brunner, S. (author), Schaart, D.R. (author)Due to detector developments in the last decade, the time-of-flight (TOF) method is now commonly used to improve the quality of positron emission tomography (PET) images.

(author), Makkus, Robert (author), Megel, Stefan (author), Hauth, Martin (author), Zappa, William (author)Contemporary combined heat and power (CHP) systems are often based on fossil fuels, such as natural gas or heating oil. Thereby, small-scale cogeneration systems are intended to replace or complement traditional heating equipment in residential buildings. In addition to space heating or domestic hot water supply, electricity is generated for the...conference paper 2017
