    Analysis of new progressive diagnistic methods in the area of aircraft maintenance
    (University of Zilina, 2021) Supuka, Matej; Hrúz, Michal
    In 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.

    Evaluation of Effectiveness of Regional Airports in Central Europe by Data Envelope Analysis
    (University of Zilina, 2013) Stryčeková, Ivana; Tomová, Anna
    In the paper we evaluate economic efficiency of 20 regional airports in Central Europe (Bratislava capital airport including) within 2004 – 2010 using input oriented data envelope analysis (DEA) with constant return on scale to identify super efficiency score. The paper results contribute to airport economic benchmarking literature which is still insufficient just for airports of regional nature. Covering 12 economic inputs and outputs parameters our research revealed Bratislava airport as efficient all the period within the sample analyzed which may be subsequently used as a supportive argument when stating development strategy for Bratislava airport.
