1. 1. Development of a Compact Drive System for Total Artificial Heart

   Master-uppsats, KTH/Medicinteknik och hälsosystem

   Författare :Hossin Bakhtiari; [2023]
   Nyckelord :Total Artificial Heart; Drive System; Miniaturization; Electric Motor; Motor Performance Evaluation; Motor Selection; Totalt artificiellt hjärta; drivsystem; miniatyrisering; elektrisk motor; motorprestanda utvärdering; motor-urval;

   Sammanfattning : Over eight decades of research into total artificial hearts (TAHs) has significantly contributed  to saving end-stage heart failure patients. However, at the current stage of development TAHs have several limitations, one of them being their bulkiness. LÄS MER

3. 2. Exploration of Radar Cross Section Models and Distributed Sensing Techniques in JCAS Cell-free Massive MIMO

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

   Författare :Qinglin Zou; [2023]
   Nyckelord :Joint communication and sensing; Cell-free massive MIMO; Swerling models; Distributed Sensing; Gemensam kommunikation och avkänning; Cellfri massiv MIMO; Swerling modeller; Distributed Sensing;

   Sammanfattning : Joint Communication and Sensing (JCAS) technology enables the sharing of infrastructure, resources, and signals between communication and sensing. However, studying the performance and algorithms using appropriate target reflectivity models for detection poses a significant challenge. LÄS MER

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

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

   Författare :Simon Richter; [2023]
   Nyckelord :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;

   Sammanfattning : 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.

5. 4. Single- or Three-Phase Supply to Homes : Advantages and Disadvantages compared between Single-phase and Three-phase domestic electricity

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

   Författare :Alexander Grönblad; [2022]
   Nyckelord :Elecricity Tariff; Single-phase Supply; Three-phase Supply; Load Curve; Homes; Eltariff; Enfasmatning; Trefasmatning; Lastprofil; Bostäder;

   Sammanfattning : A three-phase power supply is a de facto standard when selecting a power supply to homes in Sweden, regardless of whether it is flat with low energy consumption or a house with electric heating. This project aims to determine the advantages and disadvantages of using a three-phase supply compared to a single-phase supply to homes. LÄS MER

7. 5. Hardware Support for FPGA  Resource Elasticity

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

   Författare :Fidan Aliyeva; [2022]
   Nyckelord :FPGA; Elasticity; Partial reconfiguration; Crossbar; WISHBONE; Multicast; FPGA; Elasticitet; Partiell omkonfigurering; Crossbar; WISHBONE; Multicast;

   Sammanfattning : FPGAs are commonly used in cloud computing due to their ability  to be  programmed  as a processor that serves a specific purpose; hence, achieving high performance at low power. On the other hand, FPGAs have a lot of resources available, which are wasted if they host a single application or serve a single user’s request. LÄS MER
