• Flow Process Models for Pipeline Diagnosis

  Publication

  • Z. Kowalczuk
  • M. S. Tatara

  - Year 2021

  This chapter examines the problem of modeling and parameterization of the transmission pipeline flow process. First, the base model for discrete time is presented, which is a reference for other developed models. Then, the diagonal approximation (AMDA) method is proposed, in which the tridiagonal sub-matrices of the recombination matrix are approximated by their diagonal counterparts, which allows for a simple determination of...

• Impact of an unsecured excavation on an underground pipeline

  Publication

  • R. Ossowski
  • K. Szarf

  - Year 2016

  The paper presents a numerical analysis of the impact of an unsecured excavation on an underground pipeline in selected soil conditions. The research was inspired by a real-life failure of a water pipeline which was caused by a nearby unsecured excavation (Sikora et al. 2015). The failure was triggered by displacement of soil mass in the vicinity of the pipeline. The study conducted in the framework of Finite Element...

• Optymalizacja: sztuka czy rzemiosło?

  Publication

  • S. Grymek
  • T. Kiczkowiak

  - Year 2012

  W pracy przedstawiono przyczyny niewielkiego zainteresowania zastosowaniem optymalizacji w praktyce inżynierskiej oraz przykłady jej skutecznego zastosowania. Wyciągnięto wniosek, że najskuteczniejszym sposobem spopularyzowania tego narzędzia jest tworzenie specjalistycznego oprogramowania wykorzystującego inżynierską wiedzę ekspercką.

• Instantaneous complex frequency for pipeline pitch estimation

  Publication

  • M. [. Kaniewska

  - Year 2010

  In the paper a pipeline algorithm for estimating the pitch of speech signal is proposed. The algorithm uses instantaneous complex frequencies estimated for four waveforms obtained by filtering the original speech signal through four bandpass complex Hilbert filters. The imaginary parts of ICFs from each channel give four candidates for pitch estimates. The decision regarding the final estimate is made based on the real parts of...

• Reduction of Derivative pipeline effort in water turbine

  Publication

  • L. Flis
  • S. Dobrociński
  • W. Kiełczyński

  - Studia Geotechnica et Mechanica - Year 2013

  The paper presents an approach to evaluate and reduce the effort of the derivative pipeline in a water turbine of a hydrostatic power station in its vulnerable spots. Potential places of the biggest effort of the structure, as well as the coefficient of displacement and safety factor related to them were identified using FEM numerical method. Pipeline reinforcement was designed and made based on FEM analysis. Original technology...

• Application of Shape Memory Alloys in Pipeline Couplings for Shipbuilding

  Publication

  • L. Matuszewski

  - Polish Maritime Research - Year 2020

  The aim of the study is to analyse shape memory alloy (SMA) pipeline joints in limited space applications for all kinds of ships. Generally, the space available in various areas on ships is strictly limited and service works usually meet many obstacles. If we consider a pipeline, the flange joints always require a larger free space around the pipe than the pipe alone. A simultaneous problem can occur with the propeller shaft line...
