1. 11. A digital integer-N PLL architecture using a pulse-shrinking TDC for mmWave applications.

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Simon Richter; [2023]
   Keywords : Phase-locked-loops; All-digital Phase-locked-loops; Time-to-digital converters; 5G and beyond; Radio-frequency design; Fas-låsd-loop; Helt-digital fas-låst-loop; Tid-till-digital-omvandlare; 5G och framtiden; Radio-frekvens design;

   Abstract : With the move of the broadband cellular network towards 5G taking off and the preparatory work on 6G and beyond starting, the need for low-complexity, low-power, and high-performance frequency synthesis using Phase-Locked Loop (PLL)s increases. As we get deeper into the mm-wave frequencies and push towards frequencies in the order of 50-70 GHz design challenges with existing PLL architectures, such as limited technology scaling and limited in-band noise performance become more apparent.

3. 12. A Study Of Using Communication Signals As Sonar Pulses In Underwater Sensor Systems

   University essay from Uppsala universitet/Signaler och system

   Author : Erica Svensson; [2022]
   Keywords : Sonar; Communication signal; Beamforming; Underwater sensor system; WLS estimator; Detection algorithm; Position estimation;

   Abstract : Underwater communication within underwater sensor network is crucial for surveillance of coast and ocean areas. The aim of this report was to examine whether it is realistic to use the communication signal which is sent from one node to another as a sonar pulse, and in such case at what distances. READ MORE

4. 13. Artificial Electronic Nurse : An IoT Based Health Monitoring System

   University essay from Blekinge Tekniska Högskola/Institutionen för matematik och naturvetenskap

   Author : Prajna Bala Sai Potnuri; Sai Charan Poliki; [2022]
   Keywords : ESP32 Wroom dev kit; Fall detection; MAX30102; MPU6050.;

   Abstract : Context. Generally, health monitoring systems are used in hospitals, which are pricey and gigantic. But with the up gradation of sensors and modules, these devices are also available in portable sizes. These devices are divided into different types according to the disease. READ MORE

5. 14. Birefringence: Effects and Implications on In-Ice Radio Detection of High-Energy Neutrinos

   University essay from Uppsala universitet/Högenergifysik

   Author : Nils Heyer; [2022]
   Keywords : Birefringence; Cosmic Neutrinos; In-ice radio propagation;

   Abstract : The detection of high-energy neutrinos in the EeV range requires new detection techniques to cope with the small expected flux. The radio detection method, utilizing Askaryan emission, can be used to detect these neutrinos in polar ice. READ MORE

6. 15. Multi-spectral X-ray imaging with a laser-plasma accelerator

   University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Author : Andrea Angella; [2022]
   Keywords : Multi-spectral imaging; single-photon counting; X-ray absorption spectroscopy; XAS; LWFA; laser-wakefield acceleration; K-edge; imaging; metal-detection algorithm; Physics and Astronomy;

   Abstract : This master thesis focuses on the creation of an algorithm to perform multispectral imaging of a metallic target using X-rays. The generation of an ultrashort high-power low-divergent X-ray beam is performed by means of a Ti:Sapphire laser driven wake-field plasma accelerator. READ MORE
