1. 1. FPGA Based Control of Multiple Electric Machines for Marine Propulsion Systems

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

   Författare :Simon Weideskog; [2024]
   Nyckelord :FPGA; Field Oriented Control; BLDC; SVPWM; SMO; Electric Drives; Electric Machines; Sliding Mode Observer; Marine Propulsion; Multiple Machines; Boat Motor; Fältorienterad styrning; marin framdrivning; elektriska drivsystem; elmaskiner; flertal maskiner; båtmotor;

   Sammanfattning : This master thesis addresses the control of electric propulsion motors in a marine context. The focus lies mainly on the implementation of field oriented control (FOC) in a field programmable gate array (FPGA). The hypothesis is that FPGAs provide performance advantages over microcontroller-based control solutions by enabling parallel processing. LÄS MER

3. 2. Sink or Swim: Sea Level Rise Adaptation in Venice, Italy : A case of citizen non-participation

   Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

   Författare :Jesper Karlsson; [2023]
   Nyckelord :civic capacity; climate change; Gioia methodology; MOSE; project development; public involvement;

   Sammanfattning : Due to global warming, sea levels will irreversibly continue to rise around the world throughout this century. Therefore, coastal urban communities will need to adapt to new environmental challenges, such as more frequent and intense flood events. LÄS MER

4. 3. Domain Knowledge and Representation Learning for Centroid Initialization in Text Clustering with k-Means : An exploratory study

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

   Författare :David Yu; [2023]
   Nyckelord :Natural language processing; Sentiment analysis; Clustering; Language model; Transformer; Heuristic; Språkteknologi; Sentimentanalys; Klustering; Språkmodell; Transformer; Heuristik;

   Sammanfattning : Text clustering is a problem where texts are partitioned into homogeneous clusters, such as partitioning them based on their sentiment value. Two techniques to address the problem are representation learning, in particular language representation models, and clustering algorithms. LÄS MER

5. 4. Characterization of NOx sensor performance under oscillating pressure conditions

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Álvaro López Méndez; [2023]
   Nyckelord :NOx sensors; engine – out heavy duty vehicle conditions; oscillating pressure; test rig testing; NOx-sensorer; motor – ut tunga fordonsförhållanden; oscillerande tryck; testriggtestning;

   Sammanfattning : The NOx sensor is essential in the modern after-treatment system. Due to the introduction of regulations from the US, it is necessary to investigate how these sensors operate in conditions of pulsating pressures generated engine - out, after the turbocharger. LÄS MER

7. 5. RocksDB Read Optimization Strategies for Streaming Applications

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

   Författare :Björkman Fredrik; [2023]
   Nyckelord :RocksDB; Data streams; Micro-batching; Data stream processing; read operation benchmark; Data stream workload simulation; RocksDB; Dataströmmar; Mikro-batching; Dataströmsprocessering; Läsoperationsmätresultat; Dataströmsarbetsbelastningssimulation;

   Sammanfattning : Modern stream processors rely on embedded key-value stores to manage state that accumulates over long-running computations and exceeds the available memory size. One of these key-value stores is RocksDB, which is widely used in many applications requiring high-performing storage with low latency. LÄS MER
