  In this paper, an analytical model for slow and fast fading effects in maritime container terminals is derived, from fitting distributions to the results of measurements performed in an actual operational environment. The proposed model is composed of a set of equations, enabling to evaluate fading statistical distribution parameters for different system and environments conditions, as a function of frequency, base station antenna...

  - ENERGIES - Rok 2022

  Wind energy (WE), which is one of the renewable energy (RE) sources for generating electricity, has been making a significant contribution to obtaining clean and green energy in recent years. Fitting an appropriate statistical distribution to the wind speed (WS) data is crucial in analyzing and estimating WE potential. Once the best suitable statistical distribution for WS data is determined, WE potential and potential yield could...

  The purpose of this paper is to solve the wind farm active power estimation problem, introducing the method which is based on a statistical approach and robust fitting. The proposed algorithm uses a statistical approach and compared to existing ones- includes a wind direction as well as the influence of turbine start-up procedure on the estimation. The results show that additional estimation inputs i.e. the wind direction and the...

  - Archives of Acoustics - Rok 2016

  The main goal of this research study is focused on creating a method for loudness scaling based on categorical perception. Its main features, such as: way of testing, calibration procedure for securing reliable results, employing natural test stimuli, etc., are described in the paper and assessed against a procedure that uses 1/2-octave bands of noise (LGOB) for the loudness growth estimation. The Mann-Whitney U-test is employed...

  • P. Otomański

  For newly developed measuring systems it is easy to estimate type B uncertainties based on the technical data of the measuring modules applied. However, it is difficult to estimate A type un-certainties due to the unknown type and level of interferences infiltrating into the measuring sys-tem. This is a particularly important problem for measurements...

• Wrażliwość probabilistyczna stanów granicznych konstrukcji - metoda Monte Carlo

  Publikacja

  • M. Skowronek

  - Rok 2015

  Praca ukazuje zastosowanie metody symulacyjnej Monte Carlo w analizie losowej konstrukcji inżynierskich. Systematyka metod losowych obejmuje ich trzy poziomy, z zaznaczeniem poziomu trzeciego, o dowolnych typach zmiennych losowych – zmiennych podstawowych problemu. Ukazano przykład modelowana losowego obciążenia wiatrem na podstawie 10-letnich pomiarów prędkości wiatru, wykazując zgodność zbioru danych z rozkładem ekstremów Gumbela....
