  1. 1. LoRa Based Moisture Sensing System

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Rasha Badran; [2023]
    Nyckelord :LoRa; moisture sensor; capacitive sensor;

    Sammanfattning : Water is an important parameter for crop growth, and the information about the moisture content in soil at different depths is very useful for farmers to determine the best time to water the soil and to irrigate farmland so as to maximize their yield. This thesis project aims to develop a prototype of a multi-depth moisture sensor probe that is part of a large sensing system used in agriculture. LÄS MER

  3. 2. Resistance Spot Welding of AlSi-coated Ultra High Strength Steel : An experimental study

    Master-uppsats, KTH/Materialvetenskap

    Författare :Kristofer Hjelmtorp; [2019]
    Nyckelord :RSW; resistance spot welding; usibor; boron steel;

    Sammanfattning : The automotive industry of today faces ever harder requirements from regulatory bodies to increase the fuel efficiency, reduce the carbon footprint and increase the safety of their vehicles. The problem is being tackled in different ways; one of them being the use of innovative materials to reduce the overall weight while improving the crash safety of the vehicle. LÄS MER

  4. 3. Improved interconnect materials for next-generation Solid Oxide Fuel Cells

    Master-uppsats, KTH/Materialvetenskap

    Författare :Pablo Collantes; [2019]
    Nyckelord :Solid Oxide Fuel Cells; High Temperature Corrosion; Self-healing; Interconnects;

    Sammanfattning : Solid Oxide Fuel Cells (SOFC) are attractive candidates in the search for cleaner and energy efficient production due to their numerous advantages such as fuel flexibility, modularity and exceptional efficiencies when combined heat and power is harnessed. A key element in its design are the interconnects which are mainly manufactured from custom ferritic stainless steels to carry the electricity between two adjacent cells. LÄS MER

  5. 4. Motor unit localization using high-density surface EMG

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Jonathan Hermansson Lundsberg; [2019]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Localization of muscle motor units (MU) using surface electromyography (sEMG) is of interest in areas including neurology, rehabilitation and prosthetic control. The aim of the thesis is to describe a method for MU localization using high-density sEMG (HDsEMG) and verify the method using simultaneous intramuscular EMG (iEMG) recordings. LÄS MER

  7. 5. A Machine Learning Approach for Better Understanding the Neuromodulation of Locomotion

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Elena Massai; [2018]
    Nyckelord :machine learning; locomotion; motor control; neuromodulation; depth electrodes;

    Sammanfattning : Motor intent and control rely on complex high-level and spinal networks. Untilnow, little is known about this system’s organization and mechanisms. Whilecognitive abilities play an essential role in planning movements, learning andmemorizing, their involvement during stereotyped tasks execution, aslocomotion, is still controversial. LÄS MER
