The Material Basis of 18th‐Century Meissen Porcelain

open access: yesArchaeometry, EarlyView.
ABSTRACT In the summer of 1708, the quest for making hard‐paste porcelain from Saxonian clay and other mineral resources succeeded. This was achieved by applying as its essential ingredient newly discovered pure kaolin from Heidelsberg near Aue, western Saxon Ore Mountains.

Survey on differential estimators for 3d point clouds

open access: yesComputer Graphics Forum, EarlyView.
Abstract Recent advancements in 3D scanning technologies, including LiDAR and photogrammetry, have enabled the precise digital replication of real‐world objects. These methods are widely used in fields such as GIS, robotics, and cultural heritage. However, the point clouds generated by such scans are often noisy and unstructured, posing challenges for ...

A Simple Grid‐Maps Pipeline: Restructured, Accelerated and Upgraded

open access: yesComputer Graphics Forum, EarlyView.
Abstract Grid maps – spatially arranged small multiples – are a powerful tool to show complex geospatial data. Meulemans et al. (2020) introduced a pipeline for computing high‐quality grid maps that are shaped roughly according to their containing geographic outlines.

Investigating Crack Resistance Behavior of Polypropylene Using J integral, J‐R Curve and Fractographic Analysis

open access: yesFatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT In this study, the fracture response of polypropylene (PP) was assessed using J‐integral evaluation, J‐R curve construction, and fractography examination. J‐R and load–displacement curves were analyzed to determine critical loads and estimate J‐integral values based on standards established for polymer fracture testing, which led to the ...

Detecting Periodicity of a General Stationary Time Series via AR(2)‐Model Fitting

open access: yesJournal of Time Series Analysis, EarlyView.
ABSTRACT Estimating the periodicity of a stationary time series via fitting a second‐order stationary autoregressive (AR(2)) model has been initiated by the seminal paper of Yule (1927). We investigate properties of this procedure when applied to general stationary processes possessing a spectral density with a dominant peak at some unknown frequency ...
