Vervoorn, R.R.E. (author), Dekker, H.R.E. (author)Rijkswaterstaat has recently stated that the use of GeoRM is obligatory for projects with major geotechnical risks. Underground construction of freeway's in high-profile areas, such as the business district Zuidas in Amsterdam or railway links in densely populated areas, always introduce major geotechnical risks. It is not uncommon for these...conference paper 2015

Taneja, P. (author), Dekker, Milan (author), van Dorsser, Cornelis (author), Vellinga, T. (author)In the present turbulent environment highlighted by energy transition, disruptive technology, and climate change impacts, adaptability and robustness are essential in long-term planning of infrastructures. This also applies to inland ports, which play an important role in the Dutch transport system. Inland ports have three major functions, i.e.,...conference paper 2019

de Haas, K. (author), Berkhout, B (author), Dekker, H.R.E. (author), Broere, W. (author)Determining the scope of (structural) renovation of aging tunnels is a complicated task and modular renovation is becoming increasingly necessary. The COB Tunnel Programme aims at developing the knowledge necessary to renovate these tunnels in a modular fashion, to reduce hindrance as much as possible. Part of this program is the development of...conference paper 2022

Jansen, A.J. (author), Dekker, M.C. (author), van der Steen, Diederik (author)Providing athletes with real-time feedback on their performance is becoming common in many sports, also in speed skating. This research-by-design project aims at finding a tool that allows the speed skater to get real-time feedback on his performance. Speed skaters often mention a so-called “good feeling” when skating behind a better skater. It...conference paper 2018

Kluba, M.M. (author), Arslan, A. (author), Stoute, R. (author), Muganda, James (author), Dekker, R. (author)This paper presents a new method for the CMOS compatible fabrication of microchannels integrated into a silicon substrate. In a single-step DRIE process (Deep Reactive Ion Etching) a network of microchannels with High Aspect Ratio (HAR) up to 10, can be etched in a silicon substrate through a mesh mask. In the same single etching step,...conference paper 2017

Joshi, S. (author), Bagani, R. (author), Beckers, Lucas (author), Dekker, R. (author)This paper reports the use of rubber—Polybutadiene as an intermediate adhesive layer for improving the adhesion between polyimide (PI) and silicone polydimethylsiloxane (PDMS) which is required for a reliable fabrication of flexible/stretchable body patches for various applications. The adhesive bond initiated by the butyl rubber (BR), apart...conference paper 2017

(author), van den Akker, Marjan (author)Railway systems occasionally get into a state of out-of-control, meaning that there is barely any train is running, even though the required resources (infrastructure, rolling stock and crew) are available. These situations can either be caused by large disruptions or unexpected propagation and accumulation of delays. Because of the large number...conference paper 2018

(author)A semi-emperical model is developed, able to capture the aeropropulsive performance characteristics of Over-The-Wing propellers at incidence. The model is based on an hypothesis on the interactions of the propeller- and wing-induced flow fields. Effects of these interactions on the both the thrust and lift are written in a form in which the...conference paper 2023

Bakhshaee Babaroud, N. (author), Dekker, R. (author), Serdijn, W.A. (author), Giagka, Vasiliki (author)Parylene-C has been used as a substrate and encapsulation material for many implantable medical devices. However, to ensure the flexibility required in some applications, minimize tissue reaction, and protect parylene from degradation in vivo an additional outmost layer of polydimethylsiloxane (PDMS) is desired. In such a scenario, the adhesion...conference paper 2020

Saccher, M. (author), Kawasaki, S. (author), Dekker, R. (author)Recently, focused ultrasound has been proposed to power deeply implanted medical devices. Almost exclusively, lead zirconate titanate (PZT) transducers are used to convert acoustic energy into electrical energy. Unfortunately, these lead containing devices cannot be hermetically encapsulated since that would block the ultrasound. We propose the...conference paper 2021

Only a few and small databases exist that allow for the development and training of brain computer interfaces (BCIs) that can decode...conference paper 2023
