  Publikacja

  • P. Szulczewski

  - Zeszyty Naukowe Akademii Morskiej w Szczecinie - Rok 2021

  During the currently ongoing development of methods for assessing the safety of ships, it is imperative that a compromise between the accuracy of the results and the accessibility of obtaining results is reached. This paper shows the calculations of a theoretical hull against damage stability regulations as included in SOLAS 2020, ICLL 66/88 as amended in 2003 and MARPOL 78. The rules included in the currently valid regulations require...

  Publikacja

  • K. Moszyk
  • M. Deja
  • M. Dobrzyński

  - Sustainability - Rok 2021

  The future increased terminal capacity will result in more container movement through the road complex and rail siding, which are one of the most critical areas (potential bottlenecks) in the container terminal. Truck turnaround time is one of the major factors that customers take into account while deciding how many container volumes they will handle through the container terminal. To enable to optimize increased traffic with...

• Consideration of the safety of bungee jumping in relation to mechanical properties of the instalation based on a jump accident in Gdynia

  Publikacja

  • A. Tomaszewska
  • P. Kłosowski

  - Engineering Transactions - Rok 2022

  This paper considers a bungee jumping accident that took place in July 2019 in Gdynia, Poland. The authors conducted an investigation to determine the cause of the bungee rope failure. It was based on mechanical tests concerning the strength of the rope as well as the calculation of the force induced in the rope during the jump. Based on the theoretical and experimental results, the rope safety factor was estimated. It appeared...

  Publikacja

  • M. Mikusova
  • J. Wachnicka
  • J. Żukowska

  - Safety - Rok 2021

  The topic of the use of mobile devices and headphones on pedestrian crossings is much less explored in comparison to the use of the mobile phone while driving. Recent years have seen many discussions on this issue, especially in foreign countries. The Slovak Republic, however, has not been giving it enough attention (and it is not mentioned in the National Road Safety Plan for the Slovak Republic from 2011 to 2020). This paper...

• Inhomogeneity of low-noise wearing courses evaluated by tire/road noise measurements using the close-proximity method

  Publikacja

  • P. Mioduszewski
  • W. Gardziejczyk

  - APPLIED ACOUSTICS - Rok 2016

  Performing numerous analyses of tire/road noise measurements on low-noise pavements during the last several years, the authors observed significant inhomogeneity of the wearing course in numerous cases, while similar problems were almost non-existent when dense pavements were measured. Three main causes of low-noise pavement inhomogeneity can be defined. The first one is imperfections in the technology used for asphalt mix production...
