• Methods of determination of C coefficient for period of rolling vessel in calm water for example of pax cargo ship

  Publication

  • A. Królicka-Gałązka

  - Technika Transportu Szynowego - Year 2013

  This article presents a different approach to calculate the C coefficient needed to determine the period of own rolling vessel in calm water. The C coefficient is usually adopted as the approximate value from the available literature, usually depending on the type of vessel, and less dependent on the loading condition. In experimental studies of marine properties (seakeeping) often have a problem with the selection of the correct...

  - Year 2023

  The aim of the project was to analyze the possibility of using machine learning and computer vision to identify (indicate the location) of all sea-going vessels located in the selected area of the open sea and to classify the main attributes of the vessel. The key elements of the project were to download data from the Sentinel-1 satellite [1], download data on the sea vessels [2], then automatically tag data and develop a detection...

  Publication

  • M. Pawłowski

  - Year 2010

  Pokazano różnice pomiędzy mnożnikami s dla promów pasażerskich, obliczonych wg konwencji SOLAS oraz metody statycznej równoważności (SEM). Obliczenia wykonane dla promu ''Polonia'' i statku prostopadłościennego wskazują na cztery wnioski. 1) W wypadku małej stateczności, mnożniki s wg SOLAS są zdecydowanie mniejsze od s wg SEM, 2) im mniejsza stateczność, tym większe różnice między nimi, 3) konwencja SOLAS niedoszacowuje rzeczywiste...

  - Polish Maritime Research - Year 2010

  This paper describes a unique engineering method intended for the preliminary designing of marine subsurface buoy mooring systems. The solved designing problem consists in determining geometrical parameters and selecting structural materials for a vessel of a buoyancy necessary to contain measuring instruments of a given mass, as well as its maximum dimensions and operational submersion depth. The assumed variability range of...

• Application of Stirling Engine Type Alpha Powered by the Recovery Energy on Vessels

  Publication

  • J. Kropiwnicki

  - Polish Maritime Research - Year 2020

  The Stirling engine is a device, in which thermal energy is transformed into mechanical without a contact between the heat carrier, and the working gas closed in the engine. Mentioned feature makes this type of engine very attractive for the use of the recovery energy, taken from other heat devices. One of the potential applications of Stirling engines is the use of thermal energy generated in the ship's engine room for producing...

  - IEEE Access - Year 2022

  The article presents a continuation of the research on the 3D multi-dipole model applied to the reproduction of magnetic signatures of ferromagnetic objects. The model structure has been modified to improve its flexibility - model parameters determined by optimization can now be located in the cuboid contour representing the object's hull. To stiffen the model, the training dataset was expanded to data collected from all four cardinal...

  Publication

  • A. Witkowska
  • R. Śmierzchalski

  - OCEAN ENGINEERING - Year 2018

  It is generally assumed in dynamic positioning of over-actuated marine vessels that the control effectiveness matrix (input matrix) is known and constant, or, in case of fault information, it is estimated by the fault detection and diagnosis system. The purpose of the study is to develop the adaptive dynamic positioning control system for an over-actuated marine vessel in the presence of uncertainties and with emphasis on limited...

  • M. A. Kamiński

  - International Journal of Environmental Research and Public Health - Year 2019

  Lubricating oils used in machines with an open cutting system, such as a saw or harvester, are applied in forest areas, gardening, in the household, and in urban greenery. During the operation of the device with an open cutting system, the lubricating oil is emitted into the environment. Therefore, the use of an oil base and refining additives of petroleum origin in the content of lubricants is associated with a negative impact...

• Modeling of subarachnoid space width change caused by blood circulation in brain vessels

  Publication

  • K. Mazur

  - Year 2014

  The subarachnoid space is an anatomic space, lying in the central nervous system, between the arachnoid membrane and the pia mater. It is filled with cerebrospinal fluid, which protects and nourishes the brain. The pathological disorder of the subarachnoid space (i.e. increase or decrease of its width) a ects the nervous system. Therefore, it is important to diagnose the width changes of the subarachnoid space. One way to support...
