Title: Modelling of Processes Governing Selective Laser Melting

Abstract: The processing parameters of Selective Laser Melting (SLM) technique have a significant impact on the functional properties of the materials. It is known that time efficient fabrication of high-quality parts with desired microstructures requires understanding of their interactions in more detail than by calculating energy density. During the talk I will introduce mechanical and structural properties of standard 316L stainless steel fabricated using SLM technique. The basics of the modelling of physical phenomena governing SLM will be discussed.

Title: Natural language processing methods in biological activity prediction and quasar detection in large scale photometric surveys.

Abstract: The first part will focus on my master ‘s thesis. Virtual screening is a process in which databases of chemical compounds are searched in order to f ind structures characterized with a high biological activity, possible drug candidates. The goal is to classify active compounds by combining the natural language processing methods with a text representation of compounds. The second part is going to cover an approach of detecting quasars with means of machine learning. Because it is not possible to fully sample extragalactic objects with spectroscopy, quasars analysis requires a proper automated approach based on photometric surveys. We are going to focus on describing a problem and showing preliminary results of our approach.

Title: Measurement of muon-antineutrino charged current cross section with single pion production in the near detector of T2K experiment

Abstract: Cross section measurement is a basic tool to examine agreement between theoretical models and experimental data. The fundamental struggle is to separate signal sample from background events. Decent measurement requires nontrivial methods in order to minimize dependency on the default model and include characteristics of the detector. This will be illustrated on the example of muon-antineutrino CC interaction on carbon with single pion production in ND280 detector of the T2K experiment.
