1. 1. Evaluation of GUI technologies for CERN's Beam Interlock System

   Kandidat-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Författare :Tobias Skarhed; [2023]
   Nyckelord :BIS; BIS2; interlocks; UCAP; Grafana; PyQt; Angular; WRAP; fixed-display; control software; dashboard; GUI evaluation;

   Sammanfattning : This thesis presents an evaluation of various graphical user interface (GUI) technologies for use in the supervision software of CERN’s Beam Interlock System (BIS). The evaluation is necessary because the current GUItechnology used by the supervision software, JavaFX, is no longer supported by Oracle. LÄS MER

3. 2. Finding new members of the VelHel-4 stream

   Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

   Författare :Lucas Johansson; [2023]
   Nyckelord :Galactic Archaeology; Milky Way; Stellar Streams; Streams; Stellar Halo; Stars; Globular Cluster; Astronomy; Astrophysics; Gaia; Chemical Abundance; Spectroscopy;

   Sammanfattning : According to the paradigm of lambda-CDM cosmology, the stellar halo ofour Galaxy has been built-up over time through the accretion of other galaxiesand star clusters. The remnants of some of these are still observable today asstellar streams, but are typically very faint and difficult to resolve amidst the farmore numerous foreground Milky Way stars. LÄS MER

4. 3. Ray-Tracing Modeling of Grating Lobe Level Reduction by Using a Dielectric Dome Antenna

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

   Författare :Lukas Jonasson; [2023]
   Nyckelord :Array antenna; Dielectric dome; Ray-Tracing; Grating lobe; Particle Swarm optimization; Gruppantenn; Dielektrisk kupol; Strålspårning; Gallerlob; Particle Swarm optimering;

   Sammanfattning : With the newly deployed fifth-generation telecommunications system and upcoming sixth-generation, high-gain antennas with hemispherical scanning capabilities are of high interest. Phased array antennas allow for fast scanning capabilities with electronic beam-steering. LÄS MER

5. 4. Validation of a new iPhone application for measurements of wrist velocity during actual work tasks

   Master-uppsats, KTH/Ergonomi

   Författare :Mohammed Abderhman Abaid; [2023]
   Nyckelord :Angular velocity; goniometer; inertial Measurement Unit IMU ; “ErgoHandMeter”; percentile; correlation iii; Vinkelhastighet; goniometer; IMU ; ErgoHandMeter ; percentil; korrelation;

   Sammanfattning : The breakthrough in mobile technology and the development of smartphones, supplied with sensing devices such as Inertial Measurement Units (IMUs), has made it possible to obtain accurate and reliable data on the angular velocity for different objects. The available technical sensors for wrist movements, such as electrogoniometers, are costly, time-consuming, and need a particular computer program to be analyzed. LÄS MER

7. 5. A Travelling Wave Slot Array based on a Double-Layer Lens for 77 GHz Automotive Radar

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

   Författare :Ashray Ugle; [2023]
   Nyckelord :Automotive radar; Double-layer lens; Gap waveguide technology; Waveguide slot; Antenna array; Lens-beamforming.; Bilradar; Dubbelskiktslins; Gap-vågledarteknik; Waveguide-kortplats; Antennuppsättning; Lens-beamforming.;

   Sammanfattning : Automotive radars have gained considerable interest in recent years for applications of road safety for vulnerable road users. The use of multipleinput and multiple-output (MIMO) technology in automotive radar has helped in realising a virtual aperture greater than the physical aperture of the antenna which has reduced the size of the overall radar module.
