    Effect of Injection Advance Angle on Auto-Ignition Delay and Response of Ad3.152 Ur Engine
    (University of Zilina, 2014) Ambrozik, Andrzej; Ambrozik, Tomasz; Kurczyński, Dariusz; Łagowski, Piotr
    The paper presents the results of experimental investigations into the effect of injection advance angle in the AD3.152UR engine on auto-ignition delay time and engine response coefficient value. In the tests, the engine operated under the full load characteristics and was fuelled by commercial diesel oil. The injection advance angle ranged αww<13, 21> CA deg. The tests aimed to assess the engine ability to adapt to variable load conditions.

    Defining Standardized Quality Level in Suburban Bus Transport
    (University of Zilina, 2014) Konečný, Vladimír; Kostolná, Mária
    The article deals with the possibilities of standardizing the quality level of suburban bus transport services. The procedures respect the legislative requirements which are valid in the Slovak Republic. The proposed theoretical methods are applied to specific measurement results of expectation and perception of the quality by the passengers in a significant transport hub of northern Slovakia, the region of Žilina. The findings will be applied in development of the standardization quality level in suburban bus transport to its anchoring into the service contract between self-governing region and operator of bus transport. This approach has not yet been applied in the Slovak Republic.

    Non Directional Beacons Checking
    (University of Zilina, 2014) Pitor, Ján; Škultéty, Filip; Götz, Karol
    This paper aims to familiarize experts from other fields with issues of flight check of Non Directional Beacon (NDB) and its assessment. The AT-940 Automatic Flight Inspection System and the aircraft PIPER SENECA are described followed by flight check specifications and procedures. Evaluated were the coverage of NDB Z, NDB ZLA located at Žilina airport and Standard Instrument Approach Procedure for runway 06. The results of evaluation are in paragraph 4. The paper is based on project “Centre of excellence for Air Transport” focused on the impact of air transport on environment photogrammetry, surveillance of electromagnetic compatibility of radio navigation aids and radio communication equipment.

    Competitiveness of Enterprises in Polish SME Sector
    (University of Zilina, 2014) Wolak-Tuzimek, Anna; Noworol-Luft, Elżbieta; Luft, Radosław
    Growth factors of competitiveness are presented empirically. Conditions of competitiveness are determined by internal factors, dependent on enterprises themselves, and by a wide range of internal factors, dependent on the macroeconomic environment. Analysis of statistics concerning 2004-2011, collected as part of the author's research, leads to the conclusion that enterprises gain competitive advantage by low pricing and high quality of their products. A growing importance of quality as a factor determining enterprise competitiveness can also be noted.
