• Stability of an imperfect truss loaded by wind

  Publikacja

  • M. Krajewski
  • P. Iwicki

  - Engineering Transactions - Rok 2016

  The present paper is devoted to the numerical research of stability of a truss loaded by wind and stiffened by elastic supports located at the top chord. The lateral braces or lateral and torsional braces were taken into account. In this paper, the linear buckling analysis re- sults for the beam and shell model were presented. Two different shapes of initial geometric imperfections were considered in the non-linear static analysis...

• Reliability of imperfect structures (simple non-linear models)

  Publikacja

  • E. Bielewicz
  • J. Górski

  - Journal of Civil Engineering and Management - Rok 2002

  Przyjęto proste modele prętów umożliwiających analizę układów o niestatecznych i statecznych punktach bifurkacji. Wykorzystano symulacyjną metodę wyznaczania niezawodności. Zastosowano metodę Monte Carlo i równania 3 poziomu dokładności. Uzyskano rozkłady prawdopodobieństwa obciążenia granicznego nieliniowych modeli konstrukcji z losowymi imperfekcjami. Wykazano, że histogramy siły granicznej modelu statecznego i niestatecznego...

• Buckling of imperfect silo shells containing bulk solids.

  Publikacja

  • J. Tejchman

  - Rok 2002

  Omówiono problem wyboczenia stalowych silosów wypełnionych materiałem sypkim. Obliczenia wykonano dla płaskiego stanu odkształcenia i dla osiowo-symetrycznego. Zachowanie materiału sypkiego było modelowane mikropolarnym hypoplastycznym prawem materiałowym, a zachowanie ścian silosu mikropolarnym sprężysto-plastycznym prawe wg von Misesa. W obliczeniach uwzględniono różne imperfekcje na ścianach.

• Improvement of Imperfect String Matching Based on Asymetric n-Grams

  Publikacja

  • J. Szymański
  • T. M. Boiński

  - Rok 2013

  Typical approaches to string comparing treats them as either different or identical without taking into account the possibility of misspelling of the word. In this article we present an approach we used for improvement of imperfect string matching that allows one to reconstruct potential string distortions. The proposed method increases the quality of imperfect string matching, allowing the lookup of misspelled words without significant...

• Application of algorithms for reasoning from imperfect knowledge in it evaluation environment

  Publikacja

  • C. Orłowski
  • T. Sitek

  - Rok 2009

  The paper describes concept of building multi-agent system dedicated for information technology evaluation or selection for IT enterprises management (IT_MAS). Authors present the model of Knowledge Processing Environment, which is one of main components of the solution. Either facts or rules will be based on IT specialists' experience. However, knowledge which is being acquisited from IT domain is mostly imperfect - uncertain...

• Semantic segmentation training using imperfect annotations and loss masking

  Publikacja

  • J. Woś

  - Rok 2021

  One of the most significant factors affecting supervised neural network training is the precision of the annotations. Also, in a case of expert group, the problem of inconsistent data annotations is an integral part of real-world supervised learning processes, well-known to researchers. One practical example is a weak ground truth delineation for medical image segmentation. In this paper, we have developed a new method of accurate...

• Energy Losses Due to Imperfect Payment Infrastructure and Payment Instruments

  Publikacja

  • O. Melnychenko

  - ENERGIES - Rok 2021

  One of the strategic objectives of the European Union is a reduction in greenhouse gas emissions and improvement of energy efficiency by at least 32.5% in different areas of the economy by 2030. However, little is known about the impact of payment in retail on energy consumption. The purpose of this paper is to assess the chain of losses of time and energy, and therefore financial losses, that occur due to the imperfection of payment...
