• Urban scene semantic segmentation using the U-Net model

  Publikacja

  • M. Ciecholewski

  - Rok 2023

  Vision-based semantic segmentation of complex urban street scenes is a very important function during autonomous driving (AD), which will become an important technology in industrialized countries in the near future. Today, advanced driver assistance systems (ADAS) improve traffic safety thanks to the application of solutions that enable detecting objects, recognising road signs, segmenting the road, etc. The basis for these functionalities...

Oprócz modeli zaczerpniętych z literatury autorzy prezentują własną koncepcje modelu stanowiąca rozszerzenie modelu sieci gęstej.This paper describes several types of the constitutive models used for the technical woven fabric description. Besides of the literatures examples of the constitutive models, the authors presented...

• Example of tension fabric structure analysis

  Publikacja

  • A. Ambroziak
  • P. Kłosowski

  - TASK Quarterly - Rok 2010

  The aim of the work is to examine two variants of non-linear strain-stress relations accepted to description of architectural fabric. Discussion on the fundamental equations of the dense net model, used in description of coated woven fabric behaviour is presented. An analysis of tensile fabric structures subjected to the dead load and initial pretension is described.

• Mechanical properties of Precontraint 1202S coated fabric under biaxial tensile test with different load ratios

  Publikacja

  • A. Ambroziak

  - CONSTRUCTION AND BUILDING MATERIALS - Rok 2015

  The paper describes a method of laboratory tests necessary for identifying the mechanical properties of polyester coated fabrics named Precontraint 1202S with PVDF surface treatment. Two sets of initial material parameters for dense net model and orthotropic model are specified. Material parameters for Precontraint 1202S coated fabric are specified on the basis of the biaxial tensile tests for different load ratios. In order to...

• Constitutive Modelling of Knitted Abdominal Implants in Numerical Simulations of Repaired Hernia Mechanics

  Publikacja

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

  - Rok 2020

  The paper presents a numerical approach to describe mechanical behavior of anisotropic textile material, which is a selected abdominal prosthesis. Two constitutive nonlinear concepts are compared. In the first one the material is considered composed from two families of threads (dense net model) and in the second one the material is homogeneous but anisotropic (as proposed by Gassel, Ogden, Holzapfel). Parameters of both models...

• Mathematical modelling of implant in an operated hernia for estimation of the repair persistence

  Publikacja

  • I. Lubowiecka

  - COMPUTER METHODS IN BIOMECHANICS AND BIOMEDICAL ENGINEERING - Rok 2015

  This paper presents mathematical modelling of an implanted surgical mesh used in the repair process of the abdominal hernia. The synthetic implant is simulated by a membrane structure. The author provides a material modelling of the implant based on the dense net model appropriate for technical fabrics. The accuracy of the proposed solution is evaluated by comparing the simulations of the dynamic behaviour of the system with the...

• CHARACTERIZATION STUDY ON MECHANICAL PROPERTIES OF POLYESTER COATED FABRIC

  Publikacja

  • A. Ambroziak

  - Archives of Civil Engineering - Rok 2020

  The scope of the paper is to determine the mechanical properties of the Precontraint 1302 polyester coated fabric under uniaxial and biaxial tensile tests. The results are compared for Precontraint 1302 fabric and other types of coated fabrics. The author applied an orthotropic model and a dense net model to reflect the polyester coated fabric performance under uniaxial and biaxial tensile tests. Material parameters are specified...

• Mechanical properties of mosquito nets in the context of hernia repair

  Publikacja

  • A. Ambroziak
  • K. Szepietowska
  • I. Lubowiecka

  - COMPUTER METHODS IN BIOMECHANICS AND BIOMEDICAL ENGINEERING - Rok 2016

  The paper deals with issue of applying mosquito nets as implants in hernia repair, which have already been used in resource-poor developing countries. Uniaxial tensile tests have been conducted on polyester mosquito meshes in two orthogonal directions. Non-linear elastic constitutive laws parameters have been identified to be applied in dense net material models. Mechanical performance of tested mosquito nets has been compared...
