  Flicker noise (1/f-like noise) is often used to assess the quality of various materials and devices. This phenomenon has been observed in different electrochemical devices or reactions (e.g., smart windows, pitting corrosion events). In our exploratory studies we consider how to measure and utilize 1/f noise for the quality assessment of supercapacitors. This task requires special attention because of enormous capacitance of the...

  We present results of the probability distribution analysis of flicker noise generated in Au nanoparticle (AuNP) decorated graphene–Si Schottky barrier diodes with and without yellow light illumination (592 nm), close to the localized surface plasmon resonance in the AuNPs (586 nm). The AuNPs occupy imperfections in the single-layer graphene and reduce the flicker noise intensity generated in the graphene layer. The estimated probability...

  - SENSORS - Year 2024

  We discuss the implementation challenges of gas sensing systems based on low-frequency noise measurements on chemoresistive sensors. Resistance fluctuations in various gas sensing materials, in a frequency range typically up to a few kHz, can enhance gas sensing by considering its intensity and the slope of power spectral density. The issues of low-frequency noise measurements in resistive gas sensors, specifically in two-dimensional...

  Artykuł dotyczy porównania dwóch rodzajów oceny hałasu w aglomeracjigdańskiej. Pierwsza ocena została przygotowana na podstawie prognozy hałasu w oparciu o mapy stworzone metodami obliczeniowymi w roku 2007. Druga ocena bazuje na rzeczywistych danych pomiarowych zarejestrowanych przez system ciągłego monitoringu działającego w aglomeracji od 2008 roku. W artykule zaprezentowano i przeprowadzono analizy występujących różnic pomiędzy...

  - Archives of Acoustics - Year 2007

  This research study presents the designed noise dosimeter based on psychoacoustical properties of the human hearing system and, at the same time. evaluation of time and frequency characteristics of noise. The designed noise dosimeter enables assessing temporary threshold shift (TTS) in critical hands in real time. In this way it is possible monitoring the hearing threshold shift continuously for people who stay in the harmful noise...
