  - PHYSICS OF FLUIDS - Year 2022

  A comparative study is performed on a circular cylinder with both flexible and rigid splitter plates (SPs). This study has the novelty of using single and dual detached SPs located downstream of the cylinder. The dimensionless gap distance between the first splitter plate and the cylinder as well as the distance between the SPs are varied. The strain of flexible SPs can be used for energy harvesting from the flow. Therefore, a...

• Pile Model Tests Using Strain Gauge Technology

  Publication

  • A. Krasiński
  • T. Kusio

  - Studia Geotechnica et Mechanica - Year 2015

  Ordinary pile bearing capacity tests are usually carried out to determine the relationship between load and displacement of pile head. The measurement system required in such tests consists of force transducer and three or four displacement gauges. The whole system is installed at the pile head above the ground level. This approach, however, does not give us complete information about the pile-soil interaction. We can only determine...

• Stochastic model of the process of diesel engine operation.

  Publication

  • J. Girtler

  - Year 2004

  Streszczenie: Najistotniejszym problemem eksploatacji silników o zapłonie samoczynnym jest problem racjonalnego (a zwłaszcza optymalnego) sterowania procesem eksploatacji tych silników. Sterowanie takie może ułatwić zastosowanie iteracyjnego algorytmu wyznaczania optymalnych strategii opracowanego przez R.A. Howarda. Wykorzystanie jednak tego algorytmu do sterowania procesem eksploatacji silników wymaga między innymi opracowania...

• An Extended Control of the Input Angle for Matrix Converters Connected with the Non-Unity Power Factor Loads.

  Publication

  • P. Szczepankowski

  - IEEE TRANSACTIONS ON INDUSTRIAL ELECTRONICS - Year 2022

  This paper proposes a novel PWM modulation algorithm for Multiphase Conventional Matrix Converters (MCMC), with 3 inputs and k outputs, using the transfer function of the load angle. The proposed approach extends the range of power angle control at the input during the operation with a maximum voltage transfer ratio. The proposed concept is based on the Direct Analytic Voltage PWM (DAV--PWM) modulation with an elliptical trajectory...
