1. 11. Real-time Autofocus Algorithm in Laser Speckle Contrast Imaging

   Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Författare :Giovanni Russo; [2023]
   Nyckelord :Laser speckle contrast imaging; Autofocus; Blind image sharpness assessment; Speckle noise; Perimed’s Perfusion Speckle Imager;

   Sammanfattning : Microcirculation is defined as the blood flow in the smallest blood vessels. Laser speckle contrast imaging (LSCI) is a full field imaging technique that provides instantaneous 2-D perfusion maps of illuminated tissues based on speckle contrast. LÄS MER

3. 12. Digital Front End Algorithms for Sub-Band Full Duplex

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Midhat Rizvi; Khaled Al-Khateeb; [2023]
   Nyckelord :Adjacent Channel Leakage Ratio; Bit Error Rate; Clipping and Filtering; Crest Factor Reduction; Digital front end; Digital Pre-Distortion Error Vector Magnitude; Frequency Division Duplex; Power Amplifier; Peak to Average Power Ratio; Peak Cancellation Crest Factor Reduction; Sub Band Full Duplex; Self-Interference Cancellation; Signal-to-Interference Noise Ratio; Signal-to-Noise Ratio; Turbo Clipping; Time Division Duplex; Technology and Engineering;

   Sammanfattning : Sub-band full duplex is a new communication scheme technology, where a single frequency band is partitioned into sub-bands for downlink (DL) and up-link(UL) transmissions, and both can take place simultaneously. The idea behind the sub-band full duplex development is to improve the throughput, and coverage and reduce the latency of the UL communication by allowing the UL reception during the DL transmission.

4. 13. Binaural realtidssimulering av hörselskador i vardagliga ljudmiljöer : Utforskandet av en immersiv upplevelse som verktyg för att skapa förståelse.

   Kandidat-uppsats, Blekinge Tekniska Högskola

   Författare :Anton Zenk; Felix Montell; [2023]
   Nyckelord :Simulation; Hearing impairments; Hearing loss; Tinnitus; Signal processing; Sound environments; Aural Diversity; Simulation; Hörselskador; Hörselnedsättning; Tinnitus; Signalprocessering; Ljudmiljöer; Aural Diversity;

   Sammanfattning : Denna artikel undersöker hur man kan skapa ökad förståelse för hörselskador i vardagliga ljudmiljöer med hjälp av en realtidssimulation. Den producerade simulationen är binaural, och innefattar olika element av hörselskador såsom hörselnedsättning och tinnitus, samt sköter uppspelning av producerade ljudmiljöer i ett 4. LÄS MER

5. 14. Filtering Pressure Oscillations in a Common Rail Pressure Signal with IIR Notch Filters for Injected Fuel Amount Estimation

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

   Författare :Marcus Akkila; Denis Ramsden; [2023]
   Nyckelord :DSP; Water hammer effect; IIR; Common-rail; Injected fuel amount estimation; Notch filter; Water hammer effect; IIR; Digital signalbehandling; Injektionsmängd; Common-rail; bandstoppfilter;

   Sammanfattning : This project concerns an inline six-cylinder (I6) diesel truck engine equipped with common-rail injection system. It has been done at the Swedish truck manufacturer Scania CV AB. The main focus is digital signal processing of the rail pressure sensor signal from the injection system. LÄS MER

7. 15. Energy-Efficient Fixed-Coefficient FIR Filters for Millimeter-Wave Radios

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

   Författare :Erik Lundell; Gustav Molin; [2023]
   Nyckelord :Technology and Engineering;

   Sammanfattning : With the introduction of millimeter-wave antenna arrays in 5G base-stations and ever-increasing data volumes, the power consumption of the signal processing in digital radio systems has increased over the last decade. This, combined with increased cost and environmental awareness, has put focus on power optimization. LÄS MER
