Deul, M.L. (author), van Lieshout, P. (author), Werter, N.P.M. (author)An accurate fatigue life prediction is vital for the effectiveness and safety of a ship structure. The fatigue limit state is typically governing and con servatism is included to provide for a safe design. On the other side, minimizing conservatism is favourable, for reasons of cost, stability and payload (i.e. weight). The fatigue life...conference paper 2022

Cai, M. (author), van Buuren, S. (author), Vink, G. (author)In most medical research, the average treatment effect is used to evaluate a treatment's performance. However, precision medicine requires knowledge of individual treatment effects: What is the difference between a unit's measurement under treatment and control conditions? In most treatment effect studies, such answers are not possible because...article 2022

Rasheed, M.B. (author), R-Moreno, M.D. (author)To meet the carbon-free energy and water demand requirements by Europe, this work has proposed an interconnected and integrated-energy-water-hydrogen (IEWH) system. Typically these systems are generally uncoupled, however, they may be interconnected and can be operated to provide green energy and water with reduced carbon footprints. This work...conference paper 2022

(author)Active prosthetic and orthotic devices have the potential to increase quality of life for individuals with impaired mobility. However, more research into human-like control methods is needed to create seamless interaction between device and user. In forward simulations the reflex-based neuromuscular model (RNM) by Song and Geyer shows promising...article 2021

Pereira, A. (author), Oertel, C. (author), Fermoselle, L.I. (author), Mendelson, J. (author), Gustafson, J. (author)We previously introduced a responsive joint attention system that uses multimodal information from users engaged in a spatial reasoning task with a robot and communicates joint attention via the robot's gaze behavior [25]. An initial evaluation of our system with adults showed it to improve users' perceptions of the robot's social presence. To...conference paper 2020

Pijpers, R.J.M. (author), Verdenius, S.A. (author), Abspoel-Bukman, L.M. (author), Maljaars, J. (author)This experimental study considers load sequence effects in fatigue crack growth in coupon specimens and in element specimens. The coupon specimens were standard edge crack configurations cyclically loaded under four point bending on base metal and welds, whereas the element specimens were full-scale axially loaded tubular joints. Whereas load...article 2020

Leonetti, D. (author), Snijder, H.H. (author), Maljaars, J. (author)This present paper concerns the application of probabilistic fatigue life prediction models based on S–N curves aiming at the estimation of the safety level for a nonload carrying cruciform joint. The safety level is expressed in terms of the reliability index as a function of the number of applied cycles. Estimating the reliability of a...article 2020

Rodriguez, C.M. (author), Pavlovic, M. (author), Dragt, R.C. (author), Schipperen, J.H.A. (author)It is known that bond line thickness has an effect on the strength of adhesively bonded joints. However, most of the work done in this area focussed on bond lines up to 3 mm thick. In this paper the thickness effect is studied of bond lines up to 10 mm thick, which is a typical thickness for civil infrastructure and maritime applications. An...conference paper 2019

Maljaars, J. (author), Bonet, E. (author), Pijpers, P.J.M. (author)Steel orthotropic decks in bridges and ferries have shown to be prone to fatigue cracking. A typical fatigue crack observed in these structures initiates at the root of the weld between the deck plate and stringer and grows into the deck plate. Due to limited fatigue test data available and the deviating characteristics of this type of crack as...article 2018

(author)Objective: Aging is accompanied by a series of changes in mature tissues that influence their properties and functions. Collagen, as one of the main extracellular components of cartilage, becomes highly crosslinked during aging. In this study, the aim was to examine whether a correlation exists between collagen crosslinking induced by artificial...article 2018

(author), Everts, V. (author)Objective Aging can cause an increase in the stiffness of hyaline cartilage as a consequence of increased protein crosslinks. By induction of crosslinking, a reduction in the diffusion of solutions into the hyaline cartilage has been observed. However, there is a lack of knowledge about the effects of aging on the biophysical and biochemical...article 2018

(author)The load that is carried in military backpacks has drastically increased over the years. Besides energy expenditure, load carriage increases joint loading which has been associated with an increased risk on injuries, discomfort, and reduced task performance. To support soldiers during load carrying, exoskeletons have been proposed. The use of...conference paper 2018

Belfroid, S.P.C. (author), Nennie, E.D. (author), Lewis, M. (author)Piping structures are generally subjected to high dynamic loading due to multiphase fluid forces. In particular subsea structures are very vulnerable as large flexibility is required to cope for instance with thermal stresses. The forces due to multiphase flow are characterized by a broadband spectrum with high amplitudes. These forces differ...conference paper 2016

In general, the fixation in cement less-type acetabular cup uses press-fit and screw methods. These methods can be applied alone or together. Based on literature survey, the additional screw inside of cup is effective; however, it has little...conference paper 2016
