Wu, J. (author), Smit, J.J. (author), Mor, A. R. (author)In practice, High-voltage (HV) cables are occasionally exposed to impulse and superimposed transient conditions, which may initiate partial discharges (PD) temporarily. Whether such PDs persist under AC voltage after the transient conditions have vanished, is at focus in the research described in this paper. Since for cross-linked polyethylene ...journal article 2020

Vasquez Cardenas, D. (author), Meysman, F.J.R. (author), Boschker, H.T.S. (author)Dark carbon fixation (DCF) by chemoautotrophic microorganisms can sustain food webs in the seafloor by local production of organic matter independent of photosynthesis. The process has received considerable attention in deep sea systems, such as hydrothermal vents, but the regulation, depth distribution, and global importance of coastal...journal article 2020

(author), Boschker, H.T.S. (author), Meysman, F.J.R. (author)Multicellularity is a key evolutionary innovation, leading to coordinated activity and resource sharing among cells, which generally occurs via the physical exchange of chemical compounds. However, filamentous cable bacteria display a unique metabolism in which redox transformations in distant cells are coupled via long-distance electron...journal article 2020

Thiruvallur Eachambadi, Raghavendran (author), Bonné, Robin (author), Cornelissen, Rob (author), Hidalgo-Martinez, Silvia (author), Vangronsveld, Jaco (author), Meysman, F.J.R. (author), Valcke, Roland (author), Cleuren, Bart (author), Manca, Jean V. (author)Cable bacteria are an emerging class of electroactive organisms that sustain unprecedented long-range electron transport across centimeter-scale distances. The local pathways of the electrical currents in these filamentous microorganisms remain unresolved. Here, the electrical circuitry in a single cable bacterium is visualized with...journal article 2020

Geelhoed, Jeanine S. (author), Van de Velde, S.J.F. (author), Meysman, F.J.R. (author)Cable bacteria (Deltaproteobacteria, Desulfobulbaceae) are long filamentous sulfur-oxidizing bacteria that generate long-distance electric currents running through the bacterial filaments. This way, they couple the oxidation of sulfide in deeper sediment layers to the reduction of oxygen or nitrate near the sediment-water interface. Cable...journal article 2020

(author)Assimilating remote sensing observations into land surface models has become common practice to improve the accuracy of terrestrial water storage (TWS) estimates such as soil moisture and groundwater, for understanding the land surface interaction with the climate system, as well as assessing regional and global water resources. Such remote...journal article 2020

Tempel, P. (author), Alfeld, M.W.E.M. (author), van der Wijk, V. (author)Cultural heritage science envisages understanding of methods and techniques used by past painters and sculptors in creating their masterpieces of art. Existing devices for in situ and non-destructive, automated scanning are large and bulky and built around the assumption of a perfectly planar surface. We are developing a lightweight, portable...book chapter 2020

Mor, A. R. (author), Muñoz Muñoz, F.A. (author), Wu, J. (author), Castro Heredia, L.C. (author)This paper presents a new wavelet analysis approach in partial discharges cable joint measurements in noisy environments. The proposed technique uses the Cross Wavelet Transform (XWT) to separate PD signals from noise and external disturbances in partial discharges measurements in cable joints using two opposite polarity sensors. The partial...journal article 2019

Yu, Mengxin (author)Miniature ultrasound probes, such as intravascular ultrasound (IVUS) probes, are valuable diagnostic tools and provide image guidance during minimallyinvasive interventions. As more ultrasound transducer elements are built into such probes to improve image quality and frame rate, it becomes increasingly difficult to accommodate the cables needed...master thesis 2019

Song, Jay (author)For assistive exoskeletons, researchers have introduced soft exoskeletons (exosuits) because they tend to be lightweight, easily worn and mobile for daily use. However, most existing devices have not introduced closed-loop control methods that users can intuitively learn and use during activities of daily living. The goal of this pilot study is...master thesis 2019

Hoogeveen, Erik (author)Context: The shift to green energy offers a need for offshore wind farms. The transition from a relatively cheap energy production from carbohydrates, to a young offshore wind energy industry needs innovations to lower the cost. Increasing the efficiency of wind turbines and lowering the installation cost of a wind farm, will eventually make...master thesis 2019

Nagarkar, Rishabh Nitin (author)An ASIC is presented for intra-vascular ultrasound imaging. Despite being connected via a single coaxial cable, it is able to pass arbitrary high voltage bipolar signals to the transducers for acoustic imaging. The thesis talks about the need to reduce the cable count to one and reviews the existing work in literature. It builds up on an...master thesis 2019
