Item Transport and Communications - celé číslo 1/2017(University of Zilina, 2017)Item A diverging diamond interchange (DDI) in conditions of road network in Slovakia(University of Zilina, 2017) Korfant, Matúš; Palúch, Ján; Kalašová, AlicaThis article focuses on the comparison of the current uncontrolled intersection and the new type of intersection. To obtain the most accurate results the intersection is simulated in the Aimsun software. The intersection is situated in Bratislava. It is formed by exits and entrances to the highway D2. The new type of the intersection is denoted as a Diverging diamond interchange (DDI) which increases the safety and fluency of the road traffic. It is most used in the interchanges.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 Temperature of the brakes and the Braking Force(University of Zilina, 2017) Rievaj, Vladimír; Mokričková, Lenka; Synák, FrantišekThe kinetic energy of the braking vehicle is changed into heat and the resulting heat increases the temperature of each part of brakes. The changed temperature affects the coefficient of friction between the brake lining and brake drum of brake disc. Unless the brakes are actuated hydraulically there is the warning brake pads and brake fluid. Object of examination in this article is the impact of repetitive braking to change of these parameters and the impact of time to change the boiling point of the brake fluid.Item Zero-fare Transport Services and Its Impact on Segment of Students(University of Zilina, 2017) Stalmašeková, Natália; Genzorová, Tatiana; Gašperová, LuciaThe end of 2014 brought big changes for the Slovak rail passenger transport market. On November 17th, the state began to cover the full cost of tickets for selected passenger groups, which caused a significant increase in passenger numbers from these groups. It is a European rarity.

The aim of this paper is to analyse, on the basis of primary research, impacts of zero- fare transport services on the segment of students. The paper also provides an overview of zero-fare transport conditions and basic characteristic of Železničná spoločnosť Slovensko.Item Measurement of Impact of Air Filter Cleanness on a Change of Engine Speed Characteristics(University of Zilina, 2017) Synák, František; Rievaj, VladimírThe paper is focused on the impact of clogged air filter on a change of speed characteristics of spark-ignition engine 1.4 MPI, 16V, 74 kW. The clogged air filter can cause deterioration in engine charging. Less air means the possibility of burning smaller amount of fuel, and thus less energy brought to the engine. This should cause a change in the size of engine torque and its power.
