van de Ven, Daan (author), Hofland, Bas (author), van Kester, Dennis (author), Smith, Greg (author), Antonini, A. (author)When constructing land reclamations, often sand is placed on top of the coarse rock of the bund surrounding the reclamation. The use of a geometrically open filter between the interface of sand and rock could be cost effective. It is expected that even a geometrically open filter with sand on top of gravel might be stable due to the arching...conference paper 2023

Almajed, Hussain M. (author), Guerra, Omar J. (author), Smith, W.A. (author), Hodge, Bri Mathias (author), Somoza Tornos, A. (author)Defossilizing the chemical industry using air-to-chemical processes offers a promising solution to driving down the emission trajectory to net-zero by 2050. Syngas is a key intermediate in the chemical industry, which can be produced from electrolytic H2 and air-sourced CO2. To techno-economically assess possible emerging air-to-syngas routes,...journal article 2023

Li, Q. (author), Finn, Adrian J. (author), Doyle, Stephen J. (author), Smith, Robin (author), Kiss, A.A. (author)This paper explores the basis on which reliable screening of distillation sequences for energy-efficient separation of zeotropic multicomponent mixtures can be carried out. A case study for the separation of natural gas liquids is used to demonstrate the approach. To solve this generic problem, a screening algorithm has been developed using...journal article 2023

(author)Three dimensional modulation-enhanced single-molecule localization techniques, such as ModLoc, offer advancements in axial localization precision across the entire field of view and axial capture range, by applying phase shifting to the illumination pattern. However, this improvement is limited by the pitch of the illumination pattern that...journal article 2023

However, existing hydrometeorological definitions fail to encompass the full range of flash droughts, many of which have distinct local physical attributes. Consequently, these events often...journal article 2023

van Dijk, Raymond (author), Kalisvaart, D. (author), Cnossen, J.P. (author), Smith, C.S. (author)Single-molecule localization microscopy requires sparse activation of emitters to circumvent the diffraction limit. In densely labeled or thick samples, overlap of emitter images is inevitable. Single-molecule localization of these samples results in a biased parameter estimate with a wrong model of the number of emitters. On the other hand,...journal article 2023

Khosravi, M. (author), Smith, Roy S. (author)The notion of reproducing kernel Hilbert space (RKHS) has emerged in system identification during the past decade. In the resulting framework, the impulse response estimation problem is formulated as a regularized optimization defined on an infinite-dimensional RKHS consisting of stable impulse responses. The consequent estimation problem is...journal article 2023
