Subthreshold Jitter in VR Can Induce Visual Discomfort
Visual-vestibular conflicts (VVCs) are a primary contributor to visually induced motion sickness (VIMS) in head-mounted displays (HMDs). Jedoch, virtual reality (VR) comfort studies often rely on exposing seated or standing users to experiences with high intensity visual motion (such as roller coasters)....
Wanderwellenlösungen der Burgers-Huxley-Gleichungen
We study the traveling wave solutions of the Burgers-Huxley equation from a geometric point of view via the qualitative theory of ordinary differential equations. By using the Poincar\’e compactification we study the global phase portraits of a family of polynomial ordinary differential...
Erweiterung der simulierten Datenerfassung verrauschter Quanten im Auftrag von Größe unter Verwendung von Pre-Trajectory Sampling mit Batch-Ausführung
Die klassische Simulation von Quantensystemen ist eine Herausforderung, as even noiseless $n$-qubit quantum states scale as $2^n$. The complexity of noisy quantum systems is even greater, requiring $2^n \times 2^n$-dimensional density matrices. Verschiedene Näherungen reduzieren den Overhead der Dichtematrix, including quantum trajectory-based methods, which instead...
SLiM-Fitnessstudio: Verstärkungslernen für die Populationsgenetik
Wir stellen SLiM-Gym vor, a Python package for integrating reinforcement learning (RL) mit Populationsgenetischen Simulationen in der Vorwärtszeit. Wright-Fisher evolutionary dynamics offer a tractable framework for modeling populations across discrete generations, yet applying RL to these systems requires a compatible training environment. SLiM-Gym connects...
Enumerative Kombinatorik von unbeschrifteten und beschrifteten zeitkonsistenten abgefressene Bäume
In der mathematischen Phylogenetik, the time-consistent galled trees provide a simple class of rooted binary network structures that can be used to represent a variety of different biological phenomena. We study the enumerative combinatorics of unlabeled and labeled time-consistent galled trees. We present...
Leistung des MORA-Geräts zum Testen der Zeitumkehrinvarianz im nuklearen Beta-Zerfall
The MORA experimental setup is designed to measure the triple-correlation D parameter in nuclear beta decay. The D coefficient is sensitive to possible violations of time-reversal invariance. The experimental configuration consists of a transparent Paul trap surrounded by a detection setup with...
Sichtgesteuertes orthopädisches Hand-Exoskelett
This paper presents the design and implementation of an AI vision-controlled orthotic hand exoskeleton to enhance rehabilitation and assistive functionality for individuals with hand mobility impairments. The system leverages a Google Coral Dev Board Micro with an Edge TPU to enable real-time...
Eigenzerlegungsparametrisierung von Strafmatrizen für Enhanced Kontrolldesign: Luft- und Raumfahrtanwendungen
Modern control algorithms require tuning of square weight/penalty matrices appearing in quadratic functions/costs to improve performance and/or stability output. Aufgrund der Einfachheit bei der Verstärkungsabstimmung und der Durchsetzung positiver Definitheit, diagonal penalty matrices are used extensively in control methods such as linear quadratic regulator (LQR),...
Analyse von Streifen in kreuzenden Fußgängerströmen mithilfe zeitlicher Matrizen und ein geometrisches Modell
Understanding pattern formation in crossing pedestrian flows is essential for analyzing and managing high-density crowd dynamics in urban environments. This study presents two complementary methodological approaches to detect and characterize stripe formations, an emergent structure observed when two pedestrian groups cross at...
Terahertz-Feldeffekt in einem zweidimensionalen Halbleiter MoS2
Zweidimensional geschichtet (2D) Materialien, with their atomic-scale thickness and tunable electronic, optisch, und mechanische Eigenschaften, open many promising pathways to significantly advance modern electronics. The field effect caused by a strong electric field, typischerweise auf MV/cm-Niveau, applied perpendicular to the material...
