  1. 1. A cross-correlation analysis of a warm super-Neptune using transit spectroscopy

    Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Elias Önerud; [2023]
    Nyckelord :Cross-correlation; cross-correlation spectroscopy; cross-correlation analysis; super-Neptune; astronomy; astrophysics; WASP-107; WASP-107 b; CRIRES ; SysRem; exoplanet; transmission spectrum; transit;

    Sammanfattning : A study was made in order to deduce whether certain chemical species, namely water (H2O) and carbon monoxide (CO), are present in the atmosphere of the exoplanet WASP-107 b, which lies about 200 light-years away from Earth in the constellation Virgo. The project was carried out at Uppsala University at the Department of Physics and Astronomy. LÄS MER

  3. 2. 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

  4. 3. Venture Capital ‘Exits’ Profile : An empirical study of venture capital backed exits in the Turkish entrepreneurial ecosystem

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

    Författare :Sedat Avsar; [2023]
    Nyckelord :Entrepreneurial ecosystem; Venture capital; Venture capital backed exits; Startup exits; Turkish venture capital ecosystem; Entreprenöriellt ekosystem; riskkapital; riskkapitalstödda exits; startup exits; turkiskt riskkapitalekosystem;

    Sammanfattning : The impact of venture capital (VC) funding for the entrepreneurial ecosystem and its value for economic development is proved by many studies and the industrial data; which is why it is important to have more insight in this area. Also considering the large risk & uncertainty involved in the VC business and its low success rates, it is particularly important to have insight into VC business performance. LÄS MER

  5. 4. 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

  7. 5. Construction of a scanning confocal microscope for Quantum Dot mapping at telecom wavelength

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Alexandros Bampis; [2023]
    Nyckelord :Nanophotonics; Quantum Dot Positioning; Photoluminescence Mapping; Scanning Microscope; Nanofotonik; Positionering av kvantprickar; Fotoluminescenskartläggning; Skanningsmikroskop;

    Sammanfattning : Future commercial applications making use of non-classical light sources require bright quantum emitters. Such emitters can be achieved by embedding self-assembled, optically active semiconductor quantum dots (QDs) in centered photonic structures. LÄS MER
