  1. 1. Evaluation of a computational method for natural fiber-reinforced plastics

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Anna Lim; [2023]
    Nyckelord :PPNF; Composite material; fiber orientation; natural fiber; coupled analysis; PPNF; Kompositmaterial; fiberorientering; naturfiber; kopplad analys;

    Sammanfattning : The importance of using natural fiber composites (NFCs) has been addressed as a substitution for synthetic fibers, such as glass and carbon fibers. This substitution contributes significantly to reducing greenhouse gas emissions, aligning with the environmental responsibilities of engineering industries. LÄS MER

  3. 2. Angular dependence of the Raman active phonon modes of Black Phosphorus

    Magister-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Armand Dominguez; [2019]
    Nyckelord :Black Phosphorus; Raman Spectroscopy; Physics and Astronomy;

    Sammanfattning : This Master’s project presents on the angular dependence of the intensity of the Raman active phonon modes of Black Phosphorus (BP), a layered 2D material with unique and attractive characteristics to the scientific and engineering community. Raman spectroscopy is an indispensable tool in quick and unobtrusive analysis of chemical structures. LÄS MER

  4. 3. Ergonomic Evaluation of Power Tool Use at Different Task and Tool Related Conditions Using a Mechanical Test Rig, Electromyography and Subjective Evaluations

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

    Författare :Ava Mazaheri; [2018]
    Nyckelord :Power Tools; Tightening Tools; Ergonomics; Subjective Ratings; Torque Tools;

    Sammanfattning : Workers within production and assembly lines are often exposed to ergonomically unfavorable tasksand conditions. Reaction forces and reaction torques generated by industrial power tools may causenot only discomfort but also health issues and injury. LÄS MER

  5. 4. Evaluation of MEMS accelerometer and gyroscope for orientation tracking nutrunner functionality

    M1-uppsats, KTH/Data- och elektroteknik

    Författare :Erik Grahn; [2017]
    Nyckelord :MEMS; IMU; accelerometer; gyroscope; nutrunner; orientation tracking; MEMS; IMU; accelerometer; gyroskop; skruvdragare; rörelseavläsning;

    Sammanfattning : In the production industry, quality control is of importance. Even though today's tools provide a lot of functionality and safety to help the operators in their job, the operators still is responsible for the final quality of the parts. Today the nutrunners manufactured by Atlas Copco use their driver to detect the tightening angle. LÄS MER

  7. 5. Orientation of Sticks and Spheres - Estimating Tensor Shape and Orientation Distribution using Diffusion NMR

    Master-uppsats, Lunds universitet/Biofysikalisk kemi

    Författare :Mikael Leveau Novén; [2015]
    Nyckelord :Diffusion NMR; ODF; NMR; Diffusion; biophysical chemistry; biofysikalisk kemi; Chemistry; Technology and Engineering;

    Sammanfattning : The diffusion characteristics of water can be measured by using NMR methods. Specifically, the diffusion profiles in samples containing domains of water barriers are of major importance to be able to describe in applications such as diffusion tensor imaging or diffusion MRI-sequences.
