1. Developing a portable, customizable, single-channel EEG device for homecare and validating it against a commercial EEG device
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : There are several commercial electroencephalography (EEG) devices on the market; however, affordable devices are not versatile for diverse research applications. The purpose of this project was to investigate how to develop a low-cost, portable, single-channel EEG system for a research institute that could be used for neurofeedback-related applications in homecare.

2. Reconfigurable Intelligent Surfaces : Optimal Positioning and Coverage Improvement
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Med framväxten av framtida mobilgenerationer bortom 5G, studeras nya teknologier för att tillgodose de förväntade kraven för framtida tjänster som Ultra-Reliable Low Latency Communications (URLLC) eller Virtual Reality. Bland dessa teknologier uppstår Reconfigurable Intelligent Surfaces (RIS) som en av de mest lovande på grund av deras förmåga att förbättra kanalen samtidigt som de bara ökar nätverkets energiförbrukning måttligt.

3. Design of a 13-Bit SAR ADC with kT/C noise cancellation technique
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : One of the main limitations of a Successive Approximation Register (SAR) Analog-to-Digital Converter (ADC) is the large input capacitance needed to achieve the desired performance. This large input capacitance increases the total area of the ADC and it imposes the use of a powerful buffer to drive it. READ MORE

4. Activity quantification of 177Lu using a 360◦ CZT gamma camera - comparison with a dual-head Anger camera
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : Background and Aim: New SPECT cameras that use CZT detectors in a 360◦ configuration has recently been introduced. Together with Bayesian reconstruction methods employing Median Root Prior (MRP) and Relative Difference Prior (RDP), this constitutes an alternative to Anger-based SPECT for activity quantification.

5. Study, Design and Optimization of Micro Coil for NMR Applications
University essay from Linköpings universitet/Institutionen för systemteknikAbstract : Nuclear Magnetic Resonance (NMR) has emerged as a powerful tool for the iden-tification and quantification of substances. A critical component within the NMRapparatus is the radio frequency coil, which determines to some extent the sen-sitivity of the NMR device. READ MORE
