Sturm, G.S.J. (author), van der Wurff, A. (author), Linnenbank, S. (author), Bonnet, J. (author), Koppert, A. (author)Thermal pathogen suppression in glasshouse horticulture by treatment with steam generated through combustion of fossil fuel will become progressively less desirable. Radio wave treatment could be an alternative. It has several advantages, the most notable is that it generates heat where it is needed in soil, so that it avoids heat losses and...journal article 2023

Hunziker, J. (author), Slob, E.C. (author), Irving, J. (author)Modeling ground penetrating radar (GPR) reflection data on glaciers with methods that require the discretization of the full subsurface domain is extremely computationally expensive because of the combination of a large domain size and the comparatively short wavelength of the signal. To address this issue, we build on and extend a previously...journal article 2023

Peng, Shaoyuan (author), Liu, Y. (author), Li, Renge (author), Wei, Ying (author), Chan, Pak Wai (author), Li, Sunwei (author)Simulating a typhoon’s wind field via mesoscale models is important in terms of providing not only the guidelines for urban planning and onshore/offshore constructions, but also the provision of insight into the dynamics and thermodynamics of tropical cyclone systems. Therefore, the errors that are contained in simulation results were...journal article 2022
