  • B. Schivinski

  - Central European Management Journal - Rok 2019

  Purpose: This paper focuses on the effects of positive and negative online reviews (eWOM) on the metrics of consumer-based brand equity (CBBE) in the context of the Polish restaurant sector. Methodology: The dedicated online survey was completed by 777 consumers, which we then analyzed with structural equation modeling. Each catering outlet was to allow to order meals online. We used descriptive analysis, confirmatory factor analysis,...

• Detection of Water on Road Surface with Acoustic Vector Sensor

  Publikacja

  • J. Kotus
  • G. Szwoch

  - SENSORS - Rok 2023

  This paper presents a new approach to detecting the presence of water on a road surface, employing an acoustic vector sensor. The proposed method is based on sound intensity analysis in the frequency domain. Acoustic events, representing road vehicles, are detected in the sound intensity signals. The direction of the incoming sound is calculated for the individual spectral components of the intensity signal, and the components...

• Localization of sound sources with dual acoustic vector sensor

  Publikacja

  • J. Kotus
  • G. Szwoch

  - Rok 2019

  The aim of the work is to estimate the position of sound sources. The proposed method uses a setup of two acoustic vector sensors (AVS). The intersection of azimuth rays from each AVS should indicate the position of a source. In practice, the result of position estimation using this method is an area rather than a point. This is a result of inaccuracy of the individual sensors, but more importantly, of the influence of a source...

• Knowledge Sharing and Managing Intellectual Capital in the Times of COVID-19: Evidence from Polish Restaurant Industry

  Publikacja

  • J. Goll
  • K. Zięba

  - Rok 2022

  Purpose: The aim of this paper is to show how restaurants in Poland managed their intellectual capital (IC) in the COVID-19 crisis and how knowledge sharing (KS) helped them to survive in those dynamically changing conditions. Methodology: The study is based on qualitative research – semi-structured interviews with a few restaurant owners and managers responsible for the business operations during...

• Calibration of acoustic vector sensor based on MEMS microphones for DOA estimation

  Publikacja

  • J. Kotus
  • G. Szwoch

  - APPLIED ACOUSTICS - Rok 2018

  A procedure of calibration of a custom 3D acoustic vector sensor (AVS) for the purpose of direction of arrival (DoA) estimation, is presented and validated in the paper. AVS devices working on a p-p principle may be constructed from standard pressure sensors and a signal processing system. However, in order to ensure accurate DoA estimation, each sensor needs to be calibrated. The proposed algorithm divides the calibration process...

• Multiple sound sources localization in free field using acoustic vector sensor

  Publikacja

  • J. Kotus

  - MULTIMEDIA TOOLS AND APPLICATIONS - Rok 2015

  Method and preliminary results of multiple sound sources localization in free field using the acoustic vector sensor were presented in this study. Direction of arrival (DOA) for considered source was determined based on sound intensity method supported by Fourier analysis. Obtained spectrum components for considered signal allowed to determine the DOA value for the particular frequency independently. The accuracy of the developed...
