   Keywords : Band-pass filters; Beam forming networks; Irregular subarrays; Particle Swarm Optimization; PCB; Penrose tessellation; Planar phased arrays; Quantization lobes; Scanning; Suspended stripline; Bandpassfilter; lobformning; matningsnätverk; Irreguljära gruppantenner; Particle Swarm Optimization; PCB; Penrose tessellation; Plana fasade gruppantenner; sidlober; Utstyrningsvinkel; Suspended stripline;

   Abstract : Massive multiple input multiple output - MIMO systems are a reality and modern communication systems rely upon this technology to cope with the increasing need for capacity and network usage. Antenna arrays are at the heart of the of the massive-MIMO system and are the enabling technology. READ MORE

3. 2. Evaluation of hardware and firmware for a Data Readout system of the PANDA Electro-Magnetic Calorimeter

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Ehsan Noorzaei; [2023]
   Keywords : ;

   Abstract : PANDA is the next generation hadron physics detector under construction at the Facility for Antiproton and Ion Research (FAIR) in Darmstadt, Germany to accurately detect and parameterize events with kinetic energies from 1MeV to 8GeV. PANDA is a 4π detector and due to its unique shape, all the readout electronics from ADC modules, power supplies, and a controller unit is housed in liquid-cooled crates mounted inside the detector.

5. 4. TEMPERATURE MODELLING OF GEAR MESH

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Ahsan Kadevalappil Ajilan; [2023]
   Keywords : Helical gear; Power loss; MATLAB; ANSYS; Spiralväxel; Strömförlust; MATLAB; ANSYS;

   Abstract : Temperature control is an essential aspect of gear design. Continuous research is going on to improve the efficiency of gear systems. Power losses or energy losses in these systems typically manifest themselves as increased temperatures and thus reducing the lifetime and overall performance of the system. READ MORE
