Walker, K.L.W. (author), Della Santina, C. (author), Giorgio-Serchi, Francesco (author)Inspired by the octopus and other animals living in water, soft robots should naturally lend themselves to underwater operations, as supported by encouraging validations in deep water scenarios. This work deals with equipping soft arms with the intelligence necessary to move precisely in wave-dominated environments, such as shallow waters...conference paper 2024

(author), Laauwen, Wouter (author)Gal/Xgal U/LDB Spectroscopic/ Stratospheric THz Observatory (GUSTO) is a NASA Explorers Mission of Opportunity that will make large scale maps of the Milky Way and Large Magellanic Cloud in three important interstellar lines: [CII], [OI], and [NII] at 158, 63, and 205 μm, respectively. During its ~75 day stratospheric (~36 km) flight, GUSTO’s 0...conference paper 2022

Walker, J.M. (author), Coraddu, A. (author), Oneto, Luca (author), Kilbourn, Stuart (author)The number of installed Floating Offshore Wind Turbines (FOWTs) has doubled since 2017, quadrupling the total installed capacity, and is expected to increase significantly over the next decade. Consequently, there is a growing consideration towards the main challenges for FOWT projects: monitoring the system's integrity, extending the...conference paper 2021

(author), Paveliev, Dmitry (author), Hu, Qing (author), Kao, Wilt (author), Vax, Vladimir (author), Walker, Chris K. (author)We report on a 4.7 THz heterodyne receiver designed for high resolution spectroscopy of the astronomically important neutral oxygen (OI) line at 4.745 THz. The receiver is based around a hot electron bolometer (HEB) mixer and quantum cascade laser (QCL) local oscillator. This receiver has been developed to fly on the Stratospheric Terahertz...conference paper 2017

Haasnoot, M. (author), Kwakkel, J.H. (author), Walker, W.E. (author)Water management in river deltas is increasingly being challenged by pressures from population growth, sea level rise, increasing variability in river runoffs, and potential climate change. Adaptation to such changes is not only determined by what is known or anticipated at present, but also by what will be experienced and learned as the future...conference paper 2012

(w.e.walker@tudelft.nl) (author)Recently, flexibility has received much attention from port researchers, designers, and managers. That is because the stability of the competitive environment of the past has been replaced by increasing uncertainty. The current economic crisis and the recent trends in ports and shipping sectors are causing port planners to rethink their approach...conference paper 2010

Taneja, P. (author), Walker, W.E. (author), Ligteringen, H. (author), Van Schuylenburg, M. (author), Van der Plas, R. (author)The evolving function of a port, and the many logistical, technological and economic uncertainties under which it must operate, make the planning and design of these complex socio-technical infrastructures very challenging. A Master Plan of a port is the instrument by which the port’s (expansion) strategy in the market place is defined....conference paper 2009

Frantzeskaki, N. (author), De Haan, A. (author), Kolfschoten, G.L. (author), Walker, W. (author)Modelling is of substantial use in policy analysis. Since policy analysis tries to facilitate decision making of complex multi-actor problems under uncertain circumstances, it needs to rationalize and simplify reality. This is the major challenge of doing policy analysis and especially modelling. The model as an abstract representation of the...conference paper 2008
