Geometry‐Aware Alignment and Comparison of Hierarchical Morse Complexes with Applications

open access: yesComputer Graphics Forum, EarlyView.
Abstract Scalar fields derived from 3D X‐ray CT scans of samples undergoing ex situ processes, such as thermal aging, chemical etching, or mechanical stress, pose unique challenges for characterizing similarities and differences across acquisitions. Typically, a sample A (source) is imaged, removed, and subjected to experimental conditions that alter ...

Individualized Pathfinding in Rugged Open Terrains Using Semantic Navigation Meshes

open access: yesComputer Graphics Forum, EarlyView.
We introduce semantic navigation meshes for complex outdoor terrains, partitioning space into regions with coherent semantic properties like slope or vegetation density. The resulting graphs enable efficient pathfinding with agent‐specific, parameterized cost functions without precomputation, accelerating search while maintaining path quality close to ...

A solution of the geodetic boundary value problem to order e3

open access: yes, 1973
A solution is obtained for the geodetic boundary value problem which defines height anomalies to + or - 5 cm, if the earth were rigid. The solution takes into account the existence of the earth's topography, together with its ellipsoidal shape and ...

FaceIt: Real‐Time On‐Device Identity‐Preserving Portrait Animation

open access: yesComputer Graphics Forum, EarlyView.
A real‐time, on‐device algorithm for animating a single portrait image using detailed facial expressions and motions from a driving video achieving visual quality that can outperform even techniques with significantly higher computational overhead. Abstract Recently, significant progress has been made in generating expressive and temporally coherent ...

On the Linearized Boundary Value Problems of Physical Geodesy

open access: yes, 1991
Three versions of the Geodetic Boundary Value Problem (GBVP) have to be distinguished, namely the fixed problem involving the assumption of a completely known boundary surface, and the vectorial and scalar formulations of the free GBVP where either the ...

The depth and breadth of capitalism at the Cape

open access: yesThe Economic History Review, EarlyView.
Abstract Limited liability company legislation was introduced to the Cape Colony in 1861. An amendment in 1892 led to wider adoption, expanding and diversifying the capital market. Using novel data from the Cape Joint Stock Archive between 1892 and 1902, this paper examines who invested, where capital flowed, and how these patterns shaped firm outcomes

Leaky Sewers Hydraulically Disconnect from Groundwater: A Proof‐of‐Concept

open access: yesGroundwater, EarlyView.
In this study, we newly demonstrate that leaky pipes can become hydraulically disconnected from the underlying groundwater—a phenomenon analogous to river–groundwater interactions. Through numerical modeling, we show that, as the groundwater table declines, the leakage flux from the pipe (in absolute terms) initially increases until a critical depth ...

A Non‐Parametric Framework for Correlation Functions on Product Metric Spaces

open access: yesInternational Statistical Review, EarlyView.
Summary We propose a non‐parametric framework for analysing data defined over products of metric spaces, a versatile class encountered in various fields. This framework accommodates non‐stationarity and seasonality and is applicable to both local and global domains, such as the Earth's surface, as well as domains evolving over linear time or time ...
