1. 1. Wrist Angle Estimation Using Two Wearable Inertial Measurement Units

   Master-uppsats, KTH/Medicinteknik och hälsosystem

   Författare :Arvin Razavi; [2023]
   Nyckelord :IMU wrist angle estimation; Wrist absolute angle; IMU-based human motion capture; orientation filter; Complementary filter; Kalman filter; IMU handledsvinkeluppskattning; handleds absolutvinkel; IMU-baserad mänsklig rörelsefångst; orienteringsfilter; komplementfilter; Kalman-filter;

   Sammanfattning : Hand-intensive work is closely related to the prevalence of upper body and hand/wrist work-related musculoskeletal disorders (WMSDs) in office work, manufacturing, service industries, as well as the healthcare industry. Some risk factors include vibrations, forceful exertions, heavy manual handling, repetitive motions, and prolonged nonneutral wrist postures. LÄS MER

3. 2. Framtagning av jämförande mät- och analysmetod för att studera komfort i barnvagnar : Ett arbete om hur komfort med avseende på vibrationerkan mätas och analyseras komparativt

   Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Industriell teknik

   Författare :Mikael Törn; Noah Påhlsson; [2023]
   Nyckelord :Barnvagn; ISO-2631:1; ISO-10326:1; komfort; vibration; mätning; dataanalys; RMS; AMV;

   Sammanfattning : This study seeks to take a closer look at how to create a reliable and repeatable method for comparative measurement and analysis of comfort regarding vibrations in strollers.To achieve this goal the study has been divided in three questions that focuses on established standards and previous studies, a construction of a measurement method and finally a construction of a data analysis method.

5. 4. Comfort of children in cycle carriers

   Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign

   Författare :Yunqi Liu; [2022]
   Nyckelord :Bicycle carrier; Child comfort; Laboratory experiment; ISO 2631-1; Cykelsläp; Barns komfort; Laboratorieförsök; ISO 2631-1;

   Sammanfattning : Carriers attached as bicycle trailers that can transport small children are becoming increasingly popular in recent years. They replace cars as a convenient and sustainable way to travel for families in commuting and other everyday activities. LÄS MER

7. 5. Time-resolved x-ray diffraction study of longitudinal optical phonons in zincblende semiconductors

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

   Författare :Lassi Linnala; [2022]
   Nyckelord :femtosecond THz radiation; ultrafast x-ray diffraction; pump-probe; longitudinal optical phonons; zincblende semiconductors; anharmonic decay; density functional perturbation theory; Physics and Astronomy;

   Sammanfattning : Anharmonic decay of longitudinal optical (LO) phonons in zincblende semiconductors is not at present well characterized due to the polar and many-body nature of the problem. Femtosecond THz radiation offers a novel route to this study, as the interaction of this radiation is directly with the phonon lattice and these THz excited phonons do not have enough energy to excite electrons over the band gap.
