  1. 1. DIAGNOSING ETHERNET CABLES USING TIME DOMAIN REFLECTOMETRY IN ETHERNET CIRCUITS

    University essay from Mälardalens universitet/Akademin för innovation, design och teknik

    Author : Anton Sundqvist; [2023]
    Keywords : ;

    Abstract : Ethernet cables are a vital component in modern systems, providing reliable data transmission between devices. However, like any other physical component, these cables are subject to wear and tear. Depending on several factors, this wear and tear can happen at different rates, and unplanned stops in a system must be avoided. READ MORE

  3. 2. Soil Moisture Sensing in Mining Waste Rock: Comparing Calibration Curves of Multiple Low-Cost Capacitance Sensors and a Single TDR Sensor

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Rasmus Jørgensen; [2022]
    Keywords : Mining waste rock; soil moisture content; volumetric water content; sensor calibration; Campbell Scientific moisture sensor; Arduino moisture sensor;

    Abstract : Measuring soil moisture content (SMC) in mining waste rock is important for assessing and modelling hydrological processes which influence pollutant release. Here, an experimental setup containing mining waste rock is established to compare the performance of 4 Arduino capacitance moisture sensors to one single Time Domain Reflectometry (TDR) sensor.

  4. 3. Locating faults in boundary wires for autonomous lawn mowers : An investigative study on methods used to locate faults in underground, low-voltage cables with focus on implementing Time Domain Reflectometer (TDR)

    University essay from Jönköping University/JTH, Avdelningen för datateknik och informatik

    Author : Mustafa Alhaj Kasem; Daniel Andersson; [2021]
    Keywords : Autonomous lawn mower; electrical fault locating; final thesis work; impedance; Time Domain Reflectometry.;

    Abstract : Purpose:The purpose of this thesis was to identify a useful solution to find the location of a broken boundary wire. By useful we mean that the solution should be inexpensive, user friendly and accurate. READ MORE

  5. 4. Distributed Temperature Sensing Using Phase-Sensitive Optical Time Domain Reflectometry

    University essay from KTH/Tillämpad fysik

    Author : Simon Ek; [2020]
    Keywords : Applied physics; Distributed optical fiber sensing; Rayleigh scattering; OTDR; phase-OTDR; Temperature; Refractive index; Strain; Correlation; RISE; Single mode fiber; SMF; Tillämpad fysik; Distribuerad optisk fibermätning; Rayleigh-spridning; OTDR; phase-OTDR; Temperatur; Brytningsindex; Töjning; RISE; Korrelation; Singelmodfiber; SMF;

    Abstract : This thesis explores and evaluates the temperature measuring capabilities of a phase-sensitive optical time-domain reflectometer (φ-OTDR), which exploits Rayleigh backscattering in normal single mode optical fibers. The device is constructed and its setup explained, and a protocol for making temperature measurements with it is developed. READ MORE

  6. 5. A Sensing Method for Quality Assessment of in-Vehicle Liquid Fluids

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Hosna Esfahani; [2016]
    Keywords : ;

    Abstract : This thesis studies a sensing method for assessing the quality of liquid fluids used invehicles such as fuel, urea, break oil and coolant, etc. Dielectric constant is one of the important indicators of liquid fluids quality. READ MORE
