1. 6. Investigations of p-type quantum dots in GaSb nanowires

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Author : In-Pyo Yeo; [2021]
   Keywords : Physics and Astronomy;

   Abstract : The purpose of this project is to investigate hole transport in p-type quantum dots formed in GaSb nanowire and operating as single hole transistors. The individual and controlled hole-spin confinement in such system yields a variety of proposed applications for spintronics or quantum computation. READ MORE

3. 7. Investigation on the energy consumption of wireless RPM sensor

   University essay from Mittuniversitetet/Institutionen för elektronikkonstruktion

   Author : Yang Song; [2020]
   Keywords : Embedded sensors; low-energy;

   Abstract : Energy-saving wireless sensors are increasingly used in the industry. Users can remotely monitor the status of the measured device and do not need to frequently replace the battery of the device. In this thesis, we studied a low-cost energy-independent wireless speed sensor system that can power itself by the rotation of the host. READ MORE

4. 8. Distributed Temperature Sensing Using Phase-Sensitive Optical Time Domain Reflectometry

   University essay from KTH/Tillämpad fysik

   Author : Simon Ek; [2020]
   Keywords : Applied physics; Distributed optical fiber sensing; Rayleigh scattering; OTDR; phase-OTDR; Temperature; Refractive index; Strain; Correlation; RISE; Single mode fiber; SMF; Tillämpad fysik; Distribuerad optisk fibermätning; Rayleigh-spridning; OTDR; phase-OTDR; Temperatur; Brytningsindex; Töjning; RISE; Korrelation; Singelmodfiber; SMF;

   Abstract : This thesis explores and evaluates the temperature measuring capabilities of a phase-sensitive optical time-domain reflectometer (φ-OTDR), which exploits Rayleigh backscattering in normal single mode optical fibers. The device is constructed and its setup explained, and a protocol for making temperature measurements with it is developed. READ MORE

5. 9. Millimeter Wave Antenna Array Calibration and Validation for 5G New Radio Access

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Manuel Jose Lopez Morales; [2018]
   Keywords : Technology and Engineering;

   Abstract : This Master thesis work was performed in Ericsson AB, Lund. It studies and validates two classes of algorithms to be used in mm-wave massive MIMO antenna arrays, for their use in the future 5G mobile communication systems. READ MORE

6. 10. Utilization of a tailormade condition monitoring device for third party motors
