Gupta, M. (author), Gürcan, Emma (author), Thompson, Andrew F. (author)Ocean heat exchanges at the marginal ice zone (MIZ) play an important role in melting sea ice. Mixed-layer eddies transport heat and ice floes across the MIZ, facilitating the pack's access to warm waters. This study explores these frontal dynamics using disk-shaped floes coupled to an upper-ocean model simulating the sea ice edge. Numerical...journal article 2024

Thompson, Jake A. (author), Gonzalez Cabaleiro, R. (author), Vilà-Nadal, Laia (author)Polyoxometalates have attracted significant interest owing to their structural diversity, redox stability, and functionality at the nanoscale. In this work, density functional theory calculations have been employed to systematically study the accuracy of various exchange-correlation functionals in reproducing experimental redox potentials,...journal article 2023

(author), Dobrovitski, V.V. (author), Thompson, Jeff D. (author)Individually addressed Er3+ ions in solid-state hosts are promising resources for quantum repeaters, because of their direct emission in the telecom band and their compatibility with silicon photonic devices. While the Er3+ electron spin provides a spin-photon interface, ancilla nuclear spins could enable multiqubit registers with longer...journal article 2023

(author)Point clouds contain high detail and high accuracy geometry representation of the scanned Earth surface parts. To manage the huge amount of data, the point clouds are traditionally organized on location and map-scale; e.g. in an octree structure, where top-levels of the tree contain few points suitable for small scale overviews and lower...journal article 2022

(author)As an extension to 2D polygonal queries, the nD-polytope queries on point clouds also play a crucial rolein nD GIS applications such as the perspective view selection. This report rst denes the nD-polytopemathematically, and then develops an ecient nD-polytope querying solution by extending an index-organized table (IOT) approach. The solution...report 2021

Liu, H. (author), Thompson, R.J. (author), van Oosterom, P.J.M. (author), Meijers, B.M. (author)Efficient spatial queries are frequently needed to extract useful information from massive nD point clouds. Most previous studies focus on developing solutions for orthogonal window queries, while rarely considering the polytope query. The latter query, which includes the widely adopted polygonal query in 2D, also plays a critical role in...journal article 2021

Gonzalez Cabaleiro, R. (author), Thompson, Jake A. (author), Vilà-Nadal, Laia (author)Fast and reliable industrial production of ammonia (NH<sub>3</sub>) is fundamentally sustaining modern society. Since the early 20<sup>th</sup> Century, NH<sub>3</sub> has been synthesized via the Haber–Bosch process, running at conditions of around 350–500°C and 100–200 times atmospheric pressure (15–20 MPa). Industrial ammonia production is...journal article 2021

Flood risk mapping projects carried out for these purposes generate a huge amount of modelling results. Previously, data submitted are highly condensed products such as typical flood inundation maps and tables for loss analysis. Original...journal article 2021

The majority of users of the Cadastre will use 2D software, and should be provided an “instant in time” plan view of the boundaries (with any 3D parcels ...conference paper 2019
