The group focuses on the artificial space objects characterization applying astronomical methods of photometry and spectroscopy. Our work is conducted using space debris research focused 0.7-m AGO70 telescope located at the Astronomical and Geophysical Observatory in Modra-Piesok (AGO) equipped with scientific CCD camera, photometric filters and spectrographs. The open position is related to attitude states estimation of high-risk upper stages and investigation of their rotation states changes over time. Work will also involve planning, coordination and in limited manner also data acquisition and reduction of objects of interest utilizing the 0.7-m AGO70 telescope and subcontracted Slovak robotic telescope network. Tasks: Task 1 – Identification of the most critical upper rocket stages in low Earth orbit and other orbital regimes in the context of potential active debris removal (ADR) missions and to improve the accuracy of predicting the atmospheric re-entry of these bodies into Earth’s atmosphere. Task 2 – Data collection and reduction, and computation of the rotational states of the most critical upper stages in low Earth orbit and other orbital regions using available methods (e.g. Vananti et al., 2023, Hrobár et al., 2026), considering the presence of rotation-axis precession movement. Task 3 – Investigation of time variations in the rotational states of rocket stages to assess their future attitude states. Task 4 – Publication(s) of the results in international peer-reviewed journal(s).

Doktorandské kolokvium KAI - Thakar Mayur Pramod (25.5.2026)

Prednášajúci: Thakar Mayur Pramod Názov: Literature Review and Research Directions in Trustworthy AI for Medical Imaging Termín: 25.5.2026, 13:10 hod., I/9
Abstrakt:
Artificial intelligence has become increasingly important in medical imaging applications such as image segmentation, classification, localization, and computer-assisted diagnosis. Although recent deep learning approaches have achieved high performance across multiple medical imaging tasks, several challenges still limit their reliability and broader clinical adoption. Current research highlights important issues related to explainability, robustness, annotation quality, model generalization, and trustworthiness in AI-assisted medical systems. This presentation summarizes the initial literature review conducted in the area of trustworthy AI for medical imaging. The review focused on understanding common deep learning workflows used in medical image analysis, including preprocessing, region of interest localization, segmentation, classification, and evaluation methodologies. Particular attention was given to explainable AI approaches, segmentation architectures such as U-Net and nnU-Net, transformer-based models, and hybrid deep learning frameworks applied in CT and CBCT imaging studies. The reviewed literature indicates that while many existing models report high quantitative performance using metrics such as Dice score, IoU, and classification accuracy, several open research problems remain insufficiently addressed. These include limited dataset availability, annotation inconsistency, lack of robustness across different imaging conditions, and limited validation of explainability methods for real clinical use. Based on these observations, the presentation outlines possible future research directions related to trustworthy and explainable AI systems in medical imaging, with a particular interest in model reliability, preprocessing workflows, segmentation robustness, and interpretable deep learning methods for clinical applications.

Seminár z teórie grafov - Matúš Matok (21.5.2026)

Prednášajúci: Matúš Matok Názov prednášky: Lonely edges in cubic graphs Termín: 21.5.2026, 9:50 hod., M 213 Abstrakt:
The notion of a perfect matching, i.e., a 1-regular spanning subgraph—a set of disjoint edges covering all vertices of a given graph—is a well studied subject in graph theory. Already in 1891, Petersen proved that each edge of a bridgeless cubic graph can be covered by a perfect matching. We say that an edge e is matching double covered if there exist two distinct perfect matchings containing e. Otherwise, e is said to be lonely. If all edges of a graph are matching double covered, so is the graph. A graph G is Klee if it is the complete graph on 4 vertices or it is obtained from another Klee graph by the operation of replacing a vertex with a triangle. This operation is denoted as G ↑ v for some vertex v ∈ V(G) of G. All Klee graphs are therefore 3-connected and planar. The classes of Klee graphs with more than three lonely edges have been characterized by Goedgebeur [1] et al. Wedefineanauxiliary structure called a decomposition tree which is a well-defined object with respect to a lonely edge e ∈ E(G) of a graph G. With the help of decomposition trees, we can argue about loneliness of e in G ↑ v for all vertices of G, giving us both positive and negative certificates of this status. This allows us to characterize all graphs with one or two lonely edges, hence completing the characterization of cubic graphs with lonely edges. References:
