  1. 1. Vibrational signals as indicators of soil fauna health? : A novel approach to environmental monitoring of ants

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Joel Fransson Forsberg; [2023]
    Keywords : Vibrations; Formica ants; Vibrometer; Vibrational signals; Imidacloprid; Before-After-Control-Impact;

    Abstract : Soil fauna provides processes of crucial importance for ecosystem functions, but our ability to observe their actions often depend on destructive methods where the integrity of the studied environment (the soil) is compromised. In this study, I develop and test a new generation of environmental monitoring tools that utilize vibrations made by soil macrofauna to inform about their performance and health. READ MORE

  3. 2. Detecting Pollutants Using Vibrations : Laser Doppler Vibrometry as a Non-Invasive Soil Organism Health Monitoring Method

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Kristoffer Wilson; [2023]
    Keywords : Vibrometer; Biotremology; Imidacloprid; Ants;

    Abstract : Due to a lack of in-situ methods capable of detecting sub-lethal effects of pollutants on soil organisms, many polluted environments are not identified prior to pollution-induced changes in the soil fauna. Therefore, there is a need to develop new non-invasive methods to measure the health of soil organisms. READ MORE

  4. 3. Comparative Study of Vision Camera-based Vibration Analysis with the Laser Vibrometer Method

    University essay from KTH/Industriell produktion

    Author : Pradeep Kumar Muralidharan; Hemanth Yanamadala; [2021]
    Keywords : OpenCV; Motion tracking; motion magnification; vision camera method; FFT; tracker; OpenCV; Rörelsesspårning; Rörelseförstoring; Synkamera -metod; FFT; Spårare;

    Abstract : Vibration analysis is a method that studies patterns in vibration data and measures vibration levels. It is usually performed on time waveforms of the vibration signal directly and on thefrequency spectrum derived by applying the Fourier Transform on the time waveform. READ MORE

  5. 4. Towards a sustainable pest management of the invasive bug Halyomorpha halys in Trentino province, Italy

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Damiano Moser; [2019]
    Keywords : Brown Marmorated Stink Bug; H. Halys; hemiptera; biotremology; Semi-Structured Interview; Thematic Analysis; invasive species; stakeholder perception;

    Abstract : Some invasive insects are agricultural pests, like the brown marmorated stinky bug (BMSB), an extremely phytophagous pentatomids. The lack of efficient low-impact control strategies makes this insect extremely dangerous for agricultural crops. In Italy, the first established populations of BMSB were found in 2012. READ MORE

  6. 5. Sound and Vibration Measurements of Metal Plates

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Forooz Shahbazi; [2009]
    Keywords : sound and vibration measurements; Metal Plates;

    Abstract : Abstract The purpose in this project is to classify different metal plates according to their size and material. The plates which are studied are small plates with the maximum size of: radius=25.75 mm and thickness=2.20 mm. READ MORE
