Pseudonyms, Propaganda, and Prints: The Life and Political Caricatures of William Dent, 1782–931

Journal for Eighteenth-Century Studies, EarlyView.
Abstract ‘Dent was probably an amateur and nothing is known of his life’, state Bryant and Heneage. Despite contributing to caricature's ‘golden age’, William Dent remains overlooked compared to contemporaries like James Gillray. Dent's extensive portfolio (1782–93) and rumoured role as a Pittite propagandist have not secured his place in the canon of ...

Class number in non Galois quartic and non abelian Galois octic function fields over finite fields

, 2006
International audienceWe consider a totally imaginary extension of a real extension of a rational function field over a finite field of odd characteristic.

Basis Networks: Learning basis functions for free‐form triangulations

Computer Graphics Forum, EarlyView.
Abstract We present a framework for learning compactly supported basis functions that define tangent continuous surfaces based on coarse irregular triangle meshes. The basis functions are represented as MLPs. Smoothness of the basis functions is achieved by using the values of Loop basis functions as the parameterization of the surface.

Quartic Bezier curve based trajectory generation for autonomous vehicles with curvature and velocity constraints

, 2014
To generate local trajectory between initial states and target states for autonomous vehicles, a feasible trajectory generation algorithm based on quartic Bezier curve is proposed. The problem of trajectory generation is firstly separated into generating

Survey on differential estimators for 3d point clouds

Computer 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 ...

Revisiting RGEs for general gauge theories

Nuclear Physics B, 2019
We revisit the renormalisation group equations (RGE) for general renormalisable gauge theories at one- and two-loop accuracy. We identify and correct various mistakes in the literature for the β-functions of the dimensionful Lagrangian parameters (the ...

FUNDAMENTAL UNITS AND REGULATORS OF AN INFINITE FAMILY OF CYCLIC QUARTIC FUNCTION FIELDS

, 2018
We explicitly determine fundamental units and regulators of an infinite family of cyclic quartic function fields L-h of unit rank 3 with a parameter h in a polynomial ring F-q[t], where F-q is the finite field of order q with characteristic not equal to ...

TT4D: Tensor‐Train‐based 4D Time‐Dependent Volume Rendering

Computer Graphics Forum, EarlyView.
Abstract Visualizing large‐scale, time‐varying volumetric data using direct volume rendering remains a significant challenge in scientific visualization, particularly as data sizes and resolutions continue to increase. One promising direction for addressing this challenge is the use of tensor decompositions, which have proven to be a useful tool for ...

Analytic approximate charged black hole solutions in Einstein–quartic gravity

Frontiers in Astronomy and Space Sciences
In this work, we employ continued fraction expansions to derive analytical, approximate charged black hole solutions in Einstein–Maxwell–quartic gravity, a theory that introduces quartic curvature corrections to the Einstein–Hilbert action.

Parallel Vectors Extraction using Bézier Clipping

Computer Graphics Forum, EarlyView.
Abstract In this paper, we propose a novel local feature extraction algorithm for the parallel vectors (PV) operator. Our method is based on Bézier clipping, which is a bracketing‐based root finding method that is commonly‐used in computer‐aided geometric design.
