Processing of light curves of satellites and space debris for the purpose of their identification Abstract:
With the increase in space traffic in recent years, precise monitoring of space debris is necessary. Observations in the form of light curves provide us with information about an object’s physical properties including shape, size, surface materials and rotation. Publicly available databases contain a huge amount of gathered light curves that can be used to train machine learning models. Pieces of space debris can fall down to the Earth in a process called reentry, therefore 3D reconstruction of this event can bring more understanding of the physical processes. ]]> [FMFI] Prednášky a semináre [FMFI] Kalendár Damas.Gruska@fmph.uniba.sk Tue, 05 Mar 2024 20:08:00 +0100 https://uniba.sk/ Thursday 7.3.2024 at 9:50 hod., Lecture room C Jozef Rajník:
Cyclic Connectivity and Cages - Considering Connections Abstract:
In this talk, we shall discuss connections between these two research topics, which have been widely studied but mostly separately. The cyclic edge-connectivity of a graph G is the smallest cardinality of an edge-cut that separates two cycles in G. It proved to be an important invariant of mostly cubic graphs and it emerges in various proofs and the study of smallest counter-examples. On the other hand, a (k,g)-cage is a smallest k-regular graph with girth g. We will show how cages and similar structures emerge in decomposing two cubic graphs with cyclic edge-connectivity k into two smaller cyclically k-connected cubic graphs. Moreover, we propose a conjecture that all (k, g)-cages are cyclically (k-2)g-edge connected, which is the larges possible value of cyclic connectivity. We prove this conjecture for (k,g)-cages with order at most roughly twice the Moore bound. This implies that the conjecture holds for some small pairs of (k,g) for which the order of a cage is not known including the famous hypothetical Moore graph of degree 57 and girth 5. This is a joint work with Robert Lukoťka and Edita Máčajová.  More information]]> [FMFI] Prednášky a semináre [FMFI] Kalendár Martin.Skoviera@fmph.uniba.sk Mon, 04 Mar 2024 21:15:00 +0100 https://uniba.sk/ Bratislava, 29 February, 2024: A team of scientists from the Faculty of Natural Sciences at... magazine's website. ]]> [RUK] Titulka - široké novinky [RUK] Spravodajský portál [RUK] Tlačové správy pr@uniba.sk Mon, 04 Mar 2024 09:18:00 +0100 https://uniba.sk/ Comenius University Bratislava has long maintained contacts with experts on security and mental...

Anomaly detection from TLE data
Abstract:
The burgeoning number of objects in Low Earth Orbit (LEO) poses a critical challenge for satellite operators, demanding robust collision avoidance measures. Although extensive databases track these objects, identifying anomalies within this data is crucial. This research investigates the application of machine learning methods to automatically detect anomalies in satellite data, potentially enhancing space situational awareness and safeguarding future space operations. ]]> [FMFI] Prednášky a semináre [FMFI] Kalendár Damas.Gruska@fmph.uniba.sk Thu, 29 Feb 2024 12:27:00 +0100 https://uniba.sk/ Students can already evaluate lessons during the winter semester 2023/2024.

Exhaustive generation of edge-girth-regular graphs
Abstract:
An edge-girth-regular(v,k,g,lambda) graph is a k-regular graph of order v and girth g such that each edge is contained in precisely lambda girth cycles. These graphs generalize several well known classes of graphs such as edge-regular graphs, edge-transitive graphs and arc-transitive graphs. In this seminar, we discuss an algorithm to exhaustively generate all edge-girth-regular graphs of a fixed order and improve several bounds on the minimum order of these graphs for certain tuples (k,g,lambda). In this seminar, we will also discuss implementation aspects that are not described in the paper.

The Petersen graph is the only snark fully covered by short cycles
Abstract:
We prove that the Petersen graph is the only snark (i.e., non-3-edge-colourable connected cubic graph) in which every edge lies in a cycle of length at most five. This talk is based on a joint work with František Kardoš and Robert Lukoťka.  More information]]> [FMFI] Prednášky a semináre [FMFI] Kalendár Martin.Skoviera@fmph.uniba.sk Mon, 26 Feb 2024 19:18:00 +0100 https://uniba.sk/ Thursday 29.2.2024 at 14:00, Lecture room M 223 Philippe Souplet  (Université Sorbonne Paris Nord):
