Power in wheelchair propulsion: Advancing the use of wearable sensors for wheelchair sports practicevan Dijk, M.P. (author)From the perspective of wheelchair sports practice, there is a growing need to provide feedback on power output. Power can be used to monitor athletes' fitness and fatigue levels, thereby preventing overtraining and potential injuries, to individualize and analyze training programs, and it is also an objective measure of effort or intensity....doctoral thesis 2024

Wilgenburg, Gert (author)The use of non-destructive tests for assessing the material status of concrete structures in the Netherlands remains relatively uncommon, despite the growing demand for the preservation of existing structures under the VenR policy of Rijkswaterstaat. Skepticism towards NDTs is reflected in the scarcity of documented case studies in publicly...master thesis 2024

Dijkman, Kirsten (author)The cycling industry is influenced by the approval of the tire pressure control system in competitive cycling. This system allows real-time adjustments to the tire-road interaction during races. The total rolling losses is the resistance resulting from tire-road interaction, incorporating resistance due to tire deformation and the dissipation of...master thesis 2024

Li, Qiang (author), Wang, Xinquan (author), Gavin, Kenneth (author), Jiang, Shengxiang (author), Diao, Hongguo (author), Wang, Kangyu (author)Extensive studies have been performed on the effectiveness of scour protection against scour erosion progression. But there is little research to date evaluating the effect of scour protection on vertical resistance behaviour of monopile foundations. This paper investigates the influence of scour protection on the vertical loading behaviour of...journal article 2024

van Dijk, M.P. (author), Hoozemans, Marco J.M. (author), Berger, M.A.M. (author), Veeger, H.E.J. (author)In wheelchair sports, there is an increasing need to monitor mechanical power in the field. When rolling resistance is known, inertial measurement units (IMUs) can be used to determine mechanical power. However, upper body (i.e., trunk) motion affects the mass distribution between the small front and large rear wheels, thus affecting rolling...journal article 2024

Wu, W. (author), Veljkovic, M. (author), Kolstein, M.H. (author), Maljaars, Johan (author), Pijpers, Richard (author)Fatigue cracks in the stiffener-to-deck plate connections of orthotropic bridge decks, initiating from the weld toe or root and propagating into the stiffener or weld throat, are experimentally and numerically studied. A statistical analysis of the structural stress is carried out using the experimental data. Automatic welded specimens show a...journal article 2024

(author), Abeel, T.E.P.M.F. (author), Camargo, Ilana L.B.C. (author)Enterococci are gut microbes of most land animals. Likely appearing first in the guts of arthropods as they moved onto land, they diversified over hundreds of millions of years adapting to evolving hosts and host diets. Over 60 enterococcal species are now known. Two species, Enterococcus faecalis and Enterococcus faecium, are common...journal article 2024

Romarís Villanueva, Javier (author), Kassapoglou, C. (author)Strain energy release rate calculations for various cases of delaminations emanating from matrix cracks are developed and used to predict the onset of delaminations and their growth size as a function of applied tension and shear loads in composite laminates. The method determines the matrix crack spacing, the delamination onset load, the...journal article 2024

Fatigue resistance analysis plays an important role in the design or assessment of OBDs. One possible fatigue failure is the crack initiating from the weld root of stiffener-to-deck plate connections at crossbeams. A full-scale experimental investigation...journal article 2024

van Dijk, M.P. (author), Hoozemans, Marco J.M. (author), Berger, M.A.M. (author), Veeger, H.E.J. (author)An important performance determinant in wheelchair sports is the power exchanged between the athlete-wheelchair combination and the environment, in short, mechanical power. Inertial measurement units (IMUs) might be used to estimate the exchanged mechanical power during wheelchair sports practice. However, to validly apply IMUs for mechanical...journal article 2024
