We achieved the main goal by meeting two sub-goals. The first sub-objective is the analysis of training organizations in Slovakia, on the basis of which we have selected entities for the second sub-objective thus the analysis of selected aircrafts suitable for PPL training. In this work we analyze three, most used training aircrafts for PPL training in Slovakia. We analyze selected aircrafts in terms of three main parts, which include, analysis of technical parameters, analysis of flight characteristics and analysis of operating parameters. Based on the given analyzes, we obtained an evaluation of the characteristics of selected aircrafts, their individual advantages and disadvantages. Other results of the work include the evaluation of criteria that are suitable for aircrafts designed for PPL training. This work can be applied in practice, especially when deciding on the selection of a training aircraft for a student or training organization.Item Analysis of new progressive diagnistic methods in the area of aircraft maintenance(University of Zilina, 2021) Supuka, Matej; Hrúz, MichalIn the area of aircraft maintenance, we commonly meet with the problem of corrosion, detection of which is one of the primary obstacles. Implementation of modern sensing techniques has a potential to bring many benefits. The objective of this work is to analyze technologies, their potential applications, and viability of switching to autonomous detection using computer aided sensing. Primary source of information were research articles from science databases such as ResearchGate and ScienceDirect. Available documents were analyzed and subsequently, useful information was extracted. First part deals with theretical knowledge about corrosion, based on which potential technologies were chosen. Those were then described, and their viability was analyzed, based on how well they could achieve our goals. Selected technologies have shown potential, however necessary solutions could not be found to enable fully switching tou autonomous computer detection. Although data acquired show many potential benefits that could arise from partial implementation of these technologies combined fith old fashioned visual inspection.Item The trend of a number of internet connections in Slovakia and selected European countries(University of Zilina, 2017) Pechota, Matej; Matúšková, MáriaNowadays we live in a time, when the number of internet connections are growing as users start sending information mostly via the internet. This article consists of statistics and information about the internet connections in Slovakia and through statistical methods we will calculate if the trend grows or rises in every district of Slovakia. The trend shows us, how important it is to adapt from postal services to new trends and take care about users who want to use postal services in this new way and to demonstrate that the number of internet connections are growing in every country. In this article we will compare statistical data between Slovakia and selected European countries. For more specific results, we should calculate the trend per citizen. The reason is, that we should compare countries where much more citizens live, than in Slovakia. This article focuses on the situation in the Slovak market. It could help to demonstrate how electronic communication and postal services could cooperate.Item ANALÝZA VYUŽÍVANIA IKT V PROCESE VZDELÁVANIA(Žilinská univerzita v Žiline, 2018) Kremeňová, Iveta; Fabuš, Juraj; Beňušová, JanaModern education - an increasingly resonant theme in every society.
