  - Journal of KONBiN - Rok 2010

  Norma PN-EN 61508 wprowadza kryteria probabilistyczne dla wyróżnionych rodzajów pracy systemów E/E/PE, które związane są z poziomami nienaruszalności bezpieczeństwa SIL. Dla systemów sterowania i zabezpieczeń, pracujących w trybie rzadkiego przywołania do działania, kryterium tym jest przeciętne prawdopodobieństwo niewypełnienia funkcji bezpieczeństwa na żądanie PFDavg. W przypadku systemów realizujących funkcje bezpieczeństwa...

  Publikacja

  • A. Tomaszewska
  • I. Lubowiecka
  • C. K. Szymczak

  - Advances in Intelligent Systems and Computing - Rok 2018

  In this paper a research towards understanding of mechanics of ventral hernia operated with the use of Physiomesh Open image in new window implant and SecureStrap Open image in new window staples is described. Experimental and numerical studies are conducted for that purpose. Experimental works cover uni-axial tension tests of the implant samples and of the implant-staples-tissue system. Also experiments on implant-staples-tissue...

  - Zeszyty Naukowe Akademii Morskiej w Szczecinie - Rok 2023

  The operation of offshore structures at sea requires the implementation of advanced systems for their permanent monitoring. There is a set of novel technologies that could be implemented to deliver a higher level of effective and safe operation of these systems. A possible novel solution may be the application of a new maritime unmanned (USV) surface and underwater vehicles/platforms (AUV). Application of such vehicles/platforms...

  • R. Śmierzchalski
  • P. Wilczynski

  - TransNav - The International Journal on Marine Navigation and Safety of Sea Transportation - Rok 2017

  One of the major activities during Ship to Ship (STS) transfer operation at sea is to safe approach the Ship to be Lightered (SBL) which moves on a constant heading with slow speed or drifting. In the paper described the manoeuvring problem for approaching during emergency STS transfer operation with oil spill. The approach manoeuvre is considered as a sequence of navigation manoeuvres in specific navigational environment with...

• Increasing the Geometrical and Interpretation Quality of Unmanned Aerial Vehicle Photogrammetry Products Using Super-Resolution Algorithms

  Publikacja

  • P. Burdziakowski

  - Remote Sensing - Rok 2020

  Unmanned aerial vehicles (UAVs) have now become very popular in photogrammetric and remote-sensing applications. Every day, these vehicles are used in new applications, new terrains, and new tasks, facing new problems. One of these problems is connected with flight altitude and the determined ground sample distance in a specific area, especially within cities and industrial and construction areas. The problem is that a safe flight...

• Three levels of fail-safe mode in MPI I/O NVRAM distributed cache

  Publikacja

  • A. Malinowski
  • P. Czarnul

  - Procedia Computer Science - Rok 2018

  The paper presents architecture and design of three versions for fail-safe data storage in a distributed cache using NVRAM in cluster nodes. In the first one, cache consistency is assured through additional buffering write requests. The second one is based on additional write log managers running on different nodes. The third one benefits from synchronization with a Parallel File System (PFS) for saving data into a new file which...

• Navigational decision support system during approach manoeuvre in emergency STS transfer operation

  Publikacja

  • A. Witkowska
  • R. Śmierzchalski
  • P. Wilczynski

  - Journal of Polish Safety and Reliability Association, Summer Safety and Reliability Seminars - Rok 2017

  The paper is concerned with the problem of safe trajectory planning for approaching during emergency STS (Ship to Ship) transfer operation with oil spill. The safe trajectory means that the way points does not cross in the area of the environment with the static and dynamic obstacles and at the same time satisfies ship's stopping and speed deceleration performance. The evolutionary path planning algorithm is used to determine trajectory...

• Strucutral steel - tensile test results

  Dane Badawcze

  open access

  • J. Kowalski

  Modern floating structures such as ships, oil platforms and offshore wind towers are built mostly of structural steel. It is a material that is subject to requirements which, when met, allows the construction and safe operation of the structure throughout its entire work cycle. One of the basic criteria that a material must meet is its strength. The...
