• Method of Skeletal System Modelling

  Publikacja

  • W. Wojnicz
  • E. Wittbrodt

  - Archive of Mechanical Engineering - Rok 2013

  An original method of skeletal system modelling is presented in detail. Using DICOM images obtained from CT and PET tests, shell models of nine bones were created (humerus, radius, ulna, scapula, clavicle, femur, tibia, fibula, pelvis). Two methods of bone behaviour are also proposed, the first method treating the bone as a solid structure and the second method treating the bone as a complex porous structure. The behaviour of model...

• The modelling method of discrete-continuous systems

  Publikacja

  • R. Hein

  - Vibrations in Physical Systems - Rok 2014

  The paper introduces a method of discrete-continuous systems modelling. In the proposed method a three-dimensional system is divided into finite elements in only two directions, with the third direction remaining continuous. The thus obtained discrete-continuous model is described by a set of partial differential equations. General difference equations of discrete system are obtained using the rigid finite element method. The limit...

• A DISCRETE-CONTINUOUS METHOD OF MECHANICAL SYSTEM MODELLING

  Publikacja

  • R. Hein

  - Polish Maritime Research - Rok 2017

  The paper describes a discrete-continuous method of dynamic system modelling. The presented approach is hybrid in its nature, as it combines the advantages of spatial discretization methods with those of continuous system modelling methods. In the proposed method, a three-dimensional system is discretised in two directions only, with the third direction remaining continuous. The thus obtained discrete-continuous model is described...

• Hybrid Method Analysis of Unshielded Guiding Structures

  Publikacja

  • M. Warecka
  • R. Lech
  • P. Kowalczyk

  - Rok 2020

  A combination of mode matching, finite element methods and generalized impedance matrix is presented in a context of propagation problems for open guiding structures. The computational domain is divided into two regions: the first one is a circular cylinder containing whole guiding structure and the second one surrounds this artificial cylinder. The impedance matrix is calculated with the use of finite element method in the first...

  • A. Gębczyńska-Janowicz

  - MEDYCYNA PRACY - Rok 2024

  The COVID-19 pandemic has resulted in changing organisational and technical requirements in the operation of treatment facilities. This paper summarises the available knowledge on the principles of hybrid design of the architecture of treatment units to ensure that different levels of sanitary and hygienic safeguards can be implemented. The basis of this narrative overview is an analysis of the existing Polish legislation on required...

• A method of nonlinearities of transformer no-load characteristic modelling

  Publikacja

  • W. Matulewicz
  • S. Baran

  - Przegląd Elektrotechniczny - Rok 2013

  A way in which changes of the no-load characteristic are taken into account in the mathematical model of the transformer is presented. Changes of saturation within core of transformer are presented as a combined non-linear flux curve. Analysis of magnetization of the transformer core and simulation of no-load state for distribution transformer of 30 kVA power rating and 15.75/0.4 kV/kV (especially supplying VLV) transformation...

• Ranking of Generation Source Locations by a Hybrid Multi-Criteria Method

  Publikacja

  • A. Lenarczyk
  • M. Jaskólski
  • P. Bućko

  - Acta Energetica - Rok 2020

  The paper presents a ranking of the locations of eight renewable energy sources (RES) made using a hybrid multi-criteria analysis method. The method is a combination of the analytical hierarchical process (AHP) method and numerical taxonomy. The considered generating sources, i.e. solar plants, biogas plants, and wind farms are sources that will significantly contribute to implementing the provisions of the energy and climate package...
