Überprüfung der Radarkameraausrichtung durch kontrastives Lernen für 3D-Objekte Erkennung
Kürzlich, 3D object detection algorithms based on radar and camera fusion have shown excellent performance, setting the stage for their application in autonomous driving perception tasks. Existing methods have focused on dealing with feature misalignment caused by the domain gap between radar...
Schnelles adaptives neuronales Online-MPC über Meta-Learning
Datengesteuerte modellprädiktive Steuerung (MPC) has demonstrated significant potential for improving robot control performance in the presence of model uncertainties. Jedoch, existing approaches often require extensive offline data collection and computationally intensive training, limiting their ability to adapt online. To address these...
DAS AUGE: Ein subjektives, absichtsbasiertes Framework mit geringer Latenz für mehrere Vorhersage der gemeinsamen Flugbahn der Verkehrsteilnehmer
Trajectory prediction is a fundamental technology for advanced autonomous driving systems and represents one of the most challenging problems in the field of cognitive intelligence. Accurately predicting the future trajectories of each traffic participant is a prerequisite for building high safety and...
PINN-MdEP: Kontinuierliche neuronale Darstellungen für den Pfad mit minimaler Energie Entdeckung in molekularen Systemen
Characterizing conformational transitions in physical systems remains a fundamental challenge in the computational sciences. Traditional sampling methods like molecular dynamics (MD) or MCMC often struggle with the high-dimensional nature of molecular systems and the high energy barriers of transitions between stable states....
Vollständig skalierbare MPC-Algorithmen für das euklidische k-Center
The $k$-center problem is a fundamental optimization problem with numerous applications in machine learning, data analysis, data mining, and communication networks. The $k$-center problem has been extensively studied in the classical sequential setting for several decades, and more recently there have been...
Schnelle und modulare Ganzkörper-Lagrange-Dynamik von Beinrobotern mit Morphologie verändern
Schnelle und modulare Modellierung mehrbeiniger Roboter (MLRs) is essential for resilient control, particularly under significant morphological changes caused by mechanical damage. Konventionelle Modelle mit fester Struktur, often developed with simplifying assumptions for nominal gaits, lack the flexibility to adapt to such scenarios. Zu...
Untersuchung der Verwendung einer selbstzündenden Sprühflamme in einem verwirbelten heißen Coflow Flamelet-generiertes Modell
Swirl-stabilized auto-igniting spray flames are essential for designing efficient and clean combustion systems. The present study performs large eddy simulations (DER) der verdünnten selbstzündenden Methanolflamme in einem verunreinigten, hot coflow of varying swirl intensities. The six-dimensional Flamelet Generated Manifold (FGM)...
Messung der Temperaturabhängigkeit des Brechungsindex von CdZnTe
We have been developing a CdZnTe immersion grating for a compact high-dispersion mid-infrared spectrometer (Wellenlängenbereich 10–18 $\mu$m, spectral resolution $R = \lambda/\Delta \lambda > 25,000$, operating temperature $T < 20$ K). Using an immersion grating, the spectrometer size can be reduced...
Untersuchung der Massenbandtopologie anhand des Zeitgrenzeneffekts in der Synthese Dimension
Eine einfallende Welle an einer zeitlichen Grenzfläche, created by an abrupt change in system parameters, erzeugt zeitgebrochene und zeitreflektierte Wellen. We find topological characteristics associated with the temporal interface that separates distinct spatial topologies and report a novel bulk-boundary correspondence for the...
Ein explizites und effizientes $O(n^2)$-Zeitalgorithmus zum Sortieren von Summenmengen
We present the first explicit comparison-based algorithm that sorts the sumset $X + Y = \{x_i + y_j,\ \Insgesamt 0 \das Ich, J < n\}$, where $X$ and $Y$ are sorted arrays of real numbers, in optimal $O(n^2)$ time and comparisons. While...
