Statistical motivation for association schemes AGT in Bratislava team, scheduled meeting
Abstract:
Association schemes originally arose in statistics, but nowadays they are extensively used in algebra and combinatorics. In the talk, we will not deal with algebraical properties of association schemes; instead, we focus on their statistical motivation. Therefore, the basic theory of: estimation in linear regression, optimal designs, and in particular, block designs will be examined; ultimately arriving at the connection between association schemes and partially balanced incomplete block designs. We will try to formulate the statistical concepts and results so that they are understandable for non-statisticians. Those of you who are not able to attend in person or who are still uncertain about the safety of attending in person are welcome to attend via MS Teams. In either case, we hope to see as many of you as possible (either in person or virtually) at our Friday gatherings. ]]> [FMFI] Prednášky a semináre [FMFI] Kalendár Martin.Macaj@fmph.uniba.sk Tue, 01 Nov 2022 20:46:00 +0100 https://uniba.sk/ Thursday 3.11.2022 at 9:50, Lecture room M/213 Dávid Wilsch:
On McKay-Miller-Širáň graphs
Abstract:
The degree-diameter problem is to determine the largest number of vertices in a graph with a given degree and diameter. There is a restricted version of this problem which asks for the largest vertex transitive graph with prescribed parameters. McKay, Miller and Širáň used voltage graphs to construct a family of graphs of diameter 2, degree (3q-r)/2 and order 2*q^2, where q is a prime power congruent to r mod 4 and r is -1, 0 or 1. McKay-Miller-Širáň are vertex transitive for r=1 while for the other two values of r they are highly symmetric but not vertex transitive. Later Šiagiová found a simpler voltage graph construction for the vertex transitive McKay-Miller-Širáň graphs, using base graphs with just two vertices - dipoles. Also, Hafner described all three families geometrically by using incidence graphs of finite affine planes. We present the results of Šiagiová and Hafner and use them to show that all McKay-Miller-Širáň graphs can be constructed as lifts of dipoles.  More information]]> [FMFI] Prednášky a semináre [FMFI] Kalendár Martin.Skoviera@fmph.uniba.sk Tue, 01 Nov 2022 20:36:00 +0100 http://https://www.fmed.uniba.sk/fileadmin/lf/aktuality/2022/obrazky/publikacia/Rozvoj_LfUK_2022_ANG.pdf in the years 2015 – 2022 [LF] Titulka - široké novinky Sat, 29 Oct 2022 18:25:00 +0200 http://fileadmin/jlf/PR/oznamy/2022/10/rektorske_a_dekanske_volno_-_SVS_2022_AJ.pdf In connection with the All Saints´Day the Rector of CU prof.

Project duration: 2022-2024 The goal of the project is to develop and validate a method for the detection and analysis of the presence of H2O molecules and organic compounds in meteoroids by investigating the emission of the atomic Hα line and molecular band of the CN radical in spectra of meteors ablating in the Earth’s atmosphere and meteorites ablated in plasma wind tunnel facilities. In our preparatory study, we have shown that strong emission of Hα in meteors is characteristic for cometary bodies with higher contents of ices and organic compounds. Experiments on simulating meteorite ablation have for the first time revealed the variations of the CN emission, which is directly linked to the content of organic compounds in meteorites and also correlates with the measured Hα line intensity. In the project, the technique developed by investigating the simulated ablation of meteorites will be applied to a large dataset of meteor spectra observations caused by meteoroids from various dynamical sources in the Solar system. We will quantify the variations of Hα a CN and define the instrumental requirements and physical conditions of ablation for the improved detection of CN. Based on these data, a concept design of a new optical spectrograph for more efficient detection of Hα a CN in meteors will be developed.]]> [FMFI] Projekty Pavol.Matlovic@fmph.uniba.sk Thu, 27 Oct 2022 11:05:00 +0200 https://uniba.sk/ Bratislava, 26 October, 2022: The Times Higher Education World University Rankings has just...
