Teixidó, Helena (author), Broggi, G.C. (author), Caglar, Baris (author), Michaud, Véronique (author)We propose a methodology to monitor the progressive saturation of a non-translucent unidirectional carbon fabric stack through its thickness by means of X-ray radiography and extract the dynamic saturation curves using image analysis. Four constant flow rate injections with increasing flow speed were carried out. These were simulated by a...journal article 2023

Gholinejad, M. (author), Edwin, Bjørn (author), Elle, Ole Jakob (author), Dankelman, J. (author), Loeve, A.J. (author)Background: Surgical process model (SPM) analysis is a great means to predict the surgical steps in a procedure as well as to predict the potential impact of new technologies. Especially in complicated and high-volume treatments, such as parenchyma sparing laparoscopic liver resection (LLR), profound process knowledge is essential for...journal article 2023

(author), Lindeboom, R.E.F. (author), Weissbrodt, D.G. (author)Purple phototrophic bacteria (PPB) show an underexplored potential for resource recovery from wastewater. Raceway reactors offer a more affordable full-scale solution on wastewater and enable useful additional aerobic processes. Current mathematical models of PPB systems provide useful mechanistic insights, but do not represent the full...journal article 2023

Zumstein, Marco (author), Chen, Qian (author), Adey, Bryan T. (author), Hall, Daniel M. (author)How bridge refurbishment projects are performed requires a trade-off between the speed and cost of the project and the amount of traffic disturbances during the project. A possible way to help reach a better balance between these two extremes is the ASTRA Bridge developed in Switzerland. The ASTRA Bridge is a 236-meter long steel ramp system...journal article 2022

Helten, Katharina (author), Eckert, Claudia (author), Gericke, Kilian (author), Vermaas, P.E. (author)In order to ensure successful product development processes, manifold modelling approaches have been developed, which cover a wide range of aspects such as responsibilities, duration of activities and dependencies. Still, an industry standard does not exist. Users of process modelling approaches are driven by different targets depending on the...journal article 2021

Wang, Zhijie (author), Zhai, Qingqing (author), Chen, P. (author)The performance of units in the same batch can exhibit considerable heterogeneity due to the variation in the raw materials and fluctuation in the manufacturing process. For products suffering performance degradation in their use, such heterogeneity often results in an increase in the dispersion of the degradation paths of units in a...journal article 2021

(author)The effect of thermal contact resistance (TCR) correlated to the degree of intimate contact (DIC) between the incoming tape and the substrate on the temperature history during laser-assisted fiber placement (LAFP) was investigated. A novel experimental methodology was designed to understand the effect with a non-contact method which did not...journal article 2021

Yuksel, O. (author), Sandberg, Michael (author), Hattel, Jesper H. (author), Akkerman, Remko (author), Baran, Ismet (author)Pultruded fiber-reinforced polymer composites are susceptible to microstructural nonuni-formity such as variability in fiber volume fraction (V<sub>f</sub> ), which can have a profound effect on process-induced residual stress. Until now, this effect of non-uniform V<sub>f</sub> distribution has been hardly addressed in the process models. In...journal article 2021

Brown, P.D. (author), Von Daniels, C. (author), Bocken, N.M.P. (author), Balkenende, R. (author)Circular oriented innovation commonly requires collaboration. Yet, to date, circular research lacks empirical investigation into collaborative processes. Collaborative processes are, however, highly researched within strategic management literature, thus offering valuable insights. The purpose of this paper is to investigate, identify and...journal article 2021

Çelik, O. (author), Peeters, D.M.J. (author), Dransfeld, C.A. (author), Teuwen, Julie J.E. (author)Intimate contact development under LAFP-specific thermal and mechanical boundary conditions/interactions and the effect of process parameters are investigated. One-layer, unidirectional strips of CF/PEKK material were placed with different process parameters on a flat tool surface to create different intimate contact conditions. The concept...journal article 2020

Yang, Y. (author), van Keulen, A. (author), Ayas, C. (author)Selective laser melting (SLM) is a widely used additive manufacturing method for building metal parts in a layer-by-layer manner thereby imposing almost no limitations on the geometrical layout of the part. The SLM process has a crucial impact on the microstructure, strength, surface quality and even the shape of the part, all of which depend on...journal article 2020

Ranjan, R. (author), Ayas, C. (author), Langelaar, Matthijs (author), van Keulen, A. (author)The powder bed fusion (PBF) process is a type of Additive Manufacturing (AM) technique which enables fabrication of highly complex geometries with unprecedented design freedom. However, PBF still suffers from manufacturing constraints which, if overlooked, can cause various types of defects in the final part. One such constraint is the local...journal article 2020

Palardy, Genevieve (author), Shi, H. (author), Levy, Arthur (author), Le Corre, Steven (author), Villegas, I.F. (author)Ultrasonic welding of thermoplastic composite materials is a promising joining technique that is now moving towards up-scaling, i.e. the assembling of large industrial parts. Despite its growing technological maturation, the assumed physical mechanisms underlying ultrasonic heating (viscoelastic heating, friction) are still insufficiently...journal article 2018

Coal has been seen as a logical choice of fuel to drive the calcium looping process as coal is already the primary fuel used to produce cement. This study assesses the impact of using different fuels, namely coal,...journal article 2018
