• Implementation of DIFAR Processing in ASW Dipping Sonar

  Publikacja

  • M. Rudnicki

  - Rok 2017

  This paper presents the implementation of the signal processing algorithm used by buoy DIFAR (Directional Frequency Analysis and Recording), that is fully operational on Polish Navy anti-submarine warfare (ASW) helicopters and ships, applied to dipping sonars for detection and tracking of submarines. The development of the DSP algorithms was a part of the modernization of sonars conducted at the Gdansk University of Technology....

• HOW TO DEFINE AND MEASURE INFORMAL EMPLOYMENT IN DEVELOPED COUNTRIES? A CASE OF POLAND

  Publikacja

  • D. Nikulin

  - Rok 2016

  The main aim of this article is to point out the possible measures of how to improve the study of informal employment in developed countries. We choose the case of Poland to examine whether the existing definitions and measurement methods are suitable for indicating the prevalence of informal employment. Firstly, we present the most popular definitions of informal employment, secondly we show the existing research on informal employment...

• How to define and measure informal employment in CEE countries - the case of Poland

  Publikacja

  • D. Nikulin

  - Emecon. Employment and economy in Central and Eastern Europe - Rok 2016

  The study of informal employment is still associated with several obstacles, from the scope of definition, through measurement methods, to policy recommendations. This article aims to revise the existing methodological frames in order to point out how to improve the study of informal employment in CEE countries. The case of Poland serves to examine whether the common definitions and measurement methods are suitable for an inclusive...

  - Coatings - Rok 2020

  A polyurethane (PU)-based powder coating reinforced with vinyltrimethoxysilane (VTMS)-functionalized ZrO2 nanoparticles (V-ZrO2) for thermal stability was developed. Chemical structure, microstructure and thermal degradation kinetics of the prepared coatings were investigated. The peak of aliphatic C–H vibrating bond in the Fourier transform infrared (FTIR) spectrum of V-ZrO2 was a signature of VTMS attachment. Scanning electron...

• Degradation of 1,4-dioxane by sono-activated persulfates for water and wastewater treatment applications

  Publikacja

  • S. H. Sonawane
  • K. Fedorov
  • M. P. Rayaroth
  • G. Boczkaj

  - Water Resources and Industry - Rok 2022

  This paper presents a hybrid advanced oxidation process (AOP) based on sonocavitational activation of persulfate (PS) for degradation of 1,4-dioxane during wastewater treatment. Application of sono-cavitation effectively convert PS to radical species demonstrating synergistic effect by increasing the reaction rate and reducing the required energy for activation. It is economically feasible and deployed alternative to the direct...

• Impact of Spatial Noise Correlation on Bearing Accuracy in DIFAR Systems

  Publikacja

  • M. Rudnicki
  • J. Marszal
  • R. Salamon

  - Archives of Acoustics - Rok 2020

  DIFAR type underwater passive systems are one of the more commonly used tools for detecting submarines. At the design stage, which usually uses computer simulations, it is necessary to generate acoustic noise of the sea. It has been shown that correlating noise significantly reduces these errors compared to the assumption that noise is uncorrelated. In addition, bearing errors have been shown to be the same in systems with a commonly...

  - Catalysts - Rok 2023

  In the chemical industry, 1,4-diethylene dioxide, commonly called dioxane, is widely used as a solvent as well as a stabilizing agent for chlorinated solvents. Due to its high miscibility, dioxane is a ubiquitous water contaminant. This study investigates the effectiveness of catalyst- and ultrasound (US)-assisted persulfate (PS) activation with regard to degrading dioxane. As a first step, a composite catalyst was prepared using...
