  1. 1. Evaluating the quality of ultrasonic signals using machine learning : A comparative study on binary classification methods applied on ultrasonic chirp signals

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Fabian Revilla; [2023]
    Nyckelord :mechatronics; machine learning; ultrasonic; bolt-tightening; nutrunner; clamp force control; elongation control; pre-load control; cross-correlation; mekatronik; maskininlärning; ultraljud; skruvdragare; klämkraft; klämkraftsåtdragning; klämkraftsreglering; korskorrelation;

    Sammanfattning : Advanced bolt-tightening tools such as automatic nutrunners are commonly used in industrial factories to streamline the assembly process. In safety-critical systems, it is crucialto control the tightening process. LÄS MER

  3. 2. Inchworm Actuating SoftRobotic Belt

    Master-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Jialun Liu; [2022]
    Nyckelord :Soft robotics; Pneumatic artificial muscles; Locomotion;

    Sammanfattning :  Soft robotics is an emerging research subject showing great promise for applications where traditional and rigid robotics is limited, for example, creating stroking sensation by using soft robotics. The purpose of this master's thesis project is to convey caress by designing and manufacturing a wearable haptic soft belt with locomotion. LÄS MER

  4. 3. Identification of mRNA expressions as biomarkers of environmental pollutants in the great pond snail (Lymnaea stagnalis)

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Johanna Eriksson; [2022]
    Nyckelord :;

    Sammanfattning : The great pond snail, Lymnaea stagnalis is considered a sensitive species to environmentalpollution and is used in ecotoxicology testing. The snail is naturally found in the environment inthe Holarctic realm in Europe, northern America and Asia but also in some parts of Australia. LÄS MER

  5. 4. Classification of ultrasonic signals using machine learning to identify optimal frequency for elongation control : Threaded fastening tools

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Mazen Bahy; [2022]
    Nyckelord :Machine Learning; Convolutions Neural Network CNN ; Barker signals; Ultrasonic sensors; Clamp-force; Threaded fastening assembly; Maskininlärning; konvolutionellt neuralt nätverk; Barker-signaler; Ultraljudssensorer; klämkraft; Åtdragningsmontering;

    Sammanfattning : Studying the preload in a screw joint has been the focus of today’s industry. The manufacturer reflects that demand by investigating different opportunities and techniques to develop this area. There are four different ways of controlling the tightening of bolts and joints to achieve the required clamp force that can hold for a specific preload. LÄS MER

  7. 5. Volatile fatty acid production and application as external carbon source for denitrification

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Cora Michelle Döhler; [2020]
    Nyckelord :VFAs; co-fermentation; primary sludge; food waste; denitrification; external carbon source; MBBR;

    Sammanfattning : By rethinking wastewater treatment plants (WWTPs) as resource recovery facilities, it is possible to de- velop the next generation of WWTPs. Moreover, it allows to accomplish environmental goals, such as reducing the CO2 footprint, and comply with increasing effluent standards regarding the concentration of nitrogen in a more sustainable way.
