A Nash-Hormander iteration and boundary elements for the Molodensky problem

open access: yes, 2013
We investigate the numerical approximation of the nonlinear Molodensky problem, which reconstructs the surface of the earth from the gravitational potential and the gravity vector.

Navigating the Flames: Comparative Analysis of Cremation Practices in the Roman and Early Medieval Periods at Gbely‐Kojatín (SK) and Přítluky (CZ)

open access: yesArchaeometry, EarlyView.
ABSTRACT Cremation became the dominant funerary practice in the Middle Danube Region during the Roman Period (RP) (1st–4th century) and reappeared in the Early Medieval Ages (EMA) (6th/7th–8th century). This study aims to reconstruct differences in cremation conditions from the Gbely‐Kojatín site (Slovakia, RP and EMA) and the Přítluky site (Czech ...

SDFs from Unoriented Point Clouds using Neural Variational Heat Distances

open access: yesComputer Graphics Forum, EarlyView.
We propose a novel variational approach for computing neural Signed Distance Fields (SDF) from unoriented point clouds. We first compute a small time step of heat flow (middle) and then use its gradient directions to solve for a neural SDF (right). Abstract We propose a novel variational approach for computing neural Signed Distance Fields (SDF) from ...

Establishing a Multibeam Sonar Evaluation Test Bed near Sidney, British Columbia [PDF]

open access: yes, 2012
The Canadian Hydrographic Service (CHS), Naval Oceanographic Office (NAVOCEANO) and the Ocean Mapping Group of the University of New Brunswick (OMG) collaborated on establishing a multibeam sonar test bed in the vicinity of the Institute of Ocean ...

Mesh Processing Non‐Meshes via Neural Displacement Fields

open access: yesComputer Graphics Forum, EarlyView.
Abstract Mesh processing pipelines are mature, but adapting them to newer non‐mesh surface representations—which enable fast rendering with compact file size—requires costly meshing or transmitting bulky meshes, negating their core benefits for streaming applications.

A Decentralized Processing Schema for Efficient and Robust Real-time Multi-GNSS Satellite Clock Estimation [PDF]

open access: yes, 2019
Real-time multi-GNSS precise point positioning (PPP) requires the support of high-rate satellite clock corrections. Due to the large number of ambiguity parameters, it is difficult to update clocks at high frequency in real-time for a large reference ...

Distribution models of polysphinctine parasitoid wasps (Hymenoptera: Ichneumonidae) reveal sampling bias and flag potentially overlooked host interactions

open access: yesInsect Conservation and Diversity, EarlyView.
We quantified the geographical overlap between parasitoid wasps and their known host spiders. We could assess which parasitoid species have more limited information about their interactions and are subject to geographical survey bias. We generated sampling bias maps to assist other researchers in identifying where the main sampling gaps are.

Establishment and validation of a hair fall atlas for Chinese men based on trichoscopy

open access: yesInternational Journal of Cosmetic Science, EarlyView.
A new hair fall atlas with 7 scales is established and validated and ready to publish as a new methodology. We observed good consistency between the dermatologists' grading (PCC >0.8), and a strong correlation shown between clinical scores and hair fall attributes based on image analysis (|p| > 0.8).

Applications of satellite and marine geodesy to operations in the ocean environment [PDF]

open access: yes
The requirements for marine and satellite geodesy technology are assessed with emphasis on the development of marine geodesy. Various programs and missions for identification of the satellite geodesy technology applicable to marine geodesy are analyzed ...
