Historia Mathematica, 1980 AbstractA discussion of the manner in which discoveries in non-Euclidean geometry, combined with the Weierstrassian attitude towards mathematics, led Wilhelm Killing, one of Weierstrass' students, to initiate a research program on foundations of geometry that led to his groundbreaking investigations on the structure of Lie algebras.

A Model for Sustainable Development in Territorial Production Systems
Sustainable Development, EarlyView.ABSTRACT The territorial production system demand innovation and adaptability to provide the majority of decisions, especially when splitting up available resources among productive sectors by the lens of sustainable development. The system's economic units evolve in dimensional profile, technical execution, and management of productive process to ...

Structural Concrete, EarlyView.Abstract This study examines the time‐dependent behavior of reinforced and prestressed concrete structures using integral‐ and rate‐type formulations, applying the concrete creep and steel relaxation models from the fib Model Code 2020. The stress–strain law for aging concrete is expressed by a second‐order differential equation, but a single rate‐type

IET Renewable Power Generation, EarlyView.Proposing a solution to the threat of ice accretion on wind turbine blades in extreme cold weather, this study introduces surrogate modelling using support vector regression for accurate prediction. The surrogate model, rigorously evaluated for reliability, demonstrates that real‐time pitch angle adjustments, informed by both the model and ...

Journal of Applied Crystallography, EarlyView.Novel linearization routines within the parameter space concept (PSC) provide an alternative approach to determine one‐dimensionally projected crystal structures from a few diffraction intensities of standard Bragg reflections, represented by piecewise analytic hyper‐surfaces, without the use of Fourier inversion.

Optimizing calibration designs with uncertainty in abilities
British Journal of Mathematical and Statistical Psychology, EarlyView.Abstract Before items can be implemented in a test, the item characteristics need to be calibrated through pretesting. To achieve high‐quality tests, it's crucial to maximize the precision of estimates obtained during item calibration. Higher precision can be attained if calibration items are allocated to examinees based on their individual abilities ...

VortexTransformer: End‐to‐End Objective Vortex Detection in 2D Unsteady Flow Using Transformers
Computer Graphics Forum, EarlyView.Abstract Vortex structures play a pivotal role in understanding complex fluid dynamics, yet defining them rigorously remains challenging. One hard criterion is that a vortex detector must be objective, i.e., it needs to be indifferent to reference frame transformations.

Inverse Simulation of Radiative Thermal Transport
Computer Graphics Forum, EarlyView.Abstract The early phase of urban planning and architectural design has a great impact on the thermal loads and characteristics of constructed buildings. It is, therefore, important to efficiently simulate thermal effects early on and rectify possible problems.

Multiphysics Simulation Methods in Computer Graphics
Computer Graphics Forum, EarlyView.Abstract Physics simulation is a cornerstone of many computer graphics applications, ranging from video games and virtual reality to visual effects and computational design. The number of techniques for physically‐based modeling and animation has thus skyrocketed over the past few decades, facilitating the simulation of a wide variety of materials and ...

Computer Graphics Forum, EarlyView.Abstract In the vast landscape of visualization research, Dimensionality Reduction (DR) and graph analysis are two popular subfields, often essential to most visual data analytics setups. DR aims to create representations to support neighborhood and similarity analysis on complex, large datasets.
