Sui, Congbiao (author), de Vos, P. (author), Hopman, J.J. (author), Visser, K. (author), Stapersma, D. (author), Ding, Yu (author)Current EEDI (Energy Efficiency Design Index) regulations striving to reduce the installed engine power on new ships for a low EEDI may lead to underpowered ships having insufficient power when operating in adverse sea conditions. In this paper, the operational safety of a low-powered ocean-going cargo ship operating in adverse sea conditions...journal article 2022

Nagayoshi, K. (author), de Wit, M. (author), Taralli, E. (author), Visser, S. (author), Ridder, M. L. (author), Gottardi, L. (author), Akamatsu, H. (author), Vaccaro, D. (author), Gao, J.R. (author)We report measured T<sub>c</sub> of superconducting Ti/Au bilayer strips with a width W varying from 5 to 50 µm. The strips were fabricated based on a Ti/Au bilayer that consists of a 41-nm-thick Ti layer to which a 280-nm-thick Au layer was added. We find that the T<sub>c</sub> drops as W decreases and the declining trend almost perfectly...journal article 2022

van der Rest, C.R. (author), Poulsen, C.B. (author), Rouvoet, A.J. (author), Visser, Eelco (author), Mosses, P.D. (author)Specifying and mechanically verifying type safe programming languages requires significant effort. This effort can in theory be reduced by defining and reusing pre-verified, modular components. In practice, however, existing approaches to modular mechanical verification require many times as much specification code as plain, monolithic...journal article 2022

(author)Fluctuating electricity prices offer potential economic savings for the consumption of electricity by flexible assets such as Electric Vehicles (EVs). This study proposes an operational bidding framework that minimizes the charging costs of an EV fleet by submitting an optimized bid to the day-ahead electricity market. The framework consists...journal article 2022

Sui, Congbiao (author), de Vos, P. (author), Stapersma, D. (author), Visser, K. (author), Hopman, J.J. (author), Ding, Yu (author)Analysis of ship propulsion system performance is often performed using detailed hydrodynamic models to assess load changes, which are subsequently compared to static engine limits, or by detailed engine models that are rarely integrated with sufficiently detailed propulsion models for load change estimation. To investigate the dynamic engine...journal article 2022

Doijode, P.S. (author), Hickel, S. (author), van Terwisga, T.J.C. (author), Visser, K. (author)We propose and analyse an optimization method that uses a machine learning approach to solve multi-objective, constrained propeller optimization problems. The method uses an online learning strategy where explainable supervised classifiers learn the location of the Pareto front and advise search strategies. The classifiers are trained with...journal article 2022

(author), Visser, Jacob J. (author), Klein, Stefan (author)Treatment planning of gastrointestinal stromal tumors (GISTs) includes distinguishing GISTs from other intra-abdominal tumors and GISTs’ molecular analysis. The aim of this study was to evaluate radiomics for distinguishing GISTs from other intra-abdominal tumors, and in GISTs, predict the c-KIT, PDGFRA, BRAF mutational status, and mitotic...journal article 2022

(author)Cold Atom technology has undergone rapid development in recent years and has been demonstrated in space in the form of cold atom scientific experiments and technology demonstrators, but has so far not been used as the fundamental sensor technology in a science mission. The European Space Agency therefore funded a 7-month project to define the...journal article 2022

Vasilikis, N. (author), Geertsma, R.D. (author), Visser, K. (author)Ship designers hardly ever receive feedback from the actual operation of their designs apart from sea acceptance trials. Similarly, crews operating the vessels do not receive a clear picture of the energy performance and environmental footprint of different options. This paper proposes a methodology based on operational data from continuous...journal article 2022

Carzana, L. (author), Visser, P.N.A.M. (author), Heiligers, M.J. (author)Solar sailing is a spacecraft propulsion method relying solely on solar radiation pressure to provide thrust and is therefore propellantless by nature. Although it represents a practical and promising propulsion system particularly suited for heliocentric flight regimes, the majority of sailcraft missions flown to date have remained Earth...journal article 2022

Meinke, K. (author), Stam, D.M. (author), Visser, P.M. (author)Context. In the near future, dedicated telescopes will observe Earth-like exoplanets in reflected parent starlight, allowing their physical characterization. Because of the huge distances, every exoplanet will remain an unresolved, single pixel, but temporal variations in the pixel’s spectral flux contain information about the planet’s surface...journal article 2022

Fayolle-Chambe, M.S. (author), Dirkx, D. (author), Lainey, V. (author), Gurvits, L. (author), Visser, P.N.A.M. (author)When reconstructing natural satellites' ephemerides from space missions' tracking data, the dynamics of the spacecraft and natural bodies are often solved for separately, in a decoupled manner. Alternatively, the ephemeris generation and spacecraft orbit determination can be performed concurrently. This method directly maps the available data...journal article 2022
