  1. 16. Sound Source Distance Estimation Using Sound Frequency Attenuation

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Frida Johnsson; Gillis Oldfeldt; [2023]
    Keywords : Technology and Engineering;

    Abstract : Estimating the distance between a sound source and receiver is an important problem. This thesis explores the possibility of estimating distance from a sound source using the attenuations regarding different frequencies over a distance. This method can be useful in cases where currently existing distance approxima- tion methods are not an option. READ MORE

  3. 17. Pond/Alex

    University essay from Lunds universitet/Industridesign

    Author : Tim Andersson; [2023]
    Keywords : Arts and Architecture; Technology and Engineering;

    Abstract : Since around 2015 there has been a huge vinyl revival going on world wide. The group which is responsible for this resurgence is mainly gen- eration-z. When you ask someone of this generation what they associate with this format you will often hear the word “nostalgic”. This “nostalgic” revival comes, however, with consequences. READ MORE

  4. 18. Deep convolution neural network for attention decoding in multi-channel EEG with conditional variational autoencoder for data augmentation

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : M Asjid Tanveer; [2023]
    Keywords : Technology and Engineering;

    Abstract : Objectives: This project aims to develop a deep learning-based attention decoding system that can distinguish between noise and speech in noise and also identify the direction of attended speech from the brain data recorded with electroencephalography (EEG) instruments. Two deep convolutional neural network (DCNN) models will be designed: (1) one DCNN model capable of classifying incoming segments of sound as speech or speech in background noise, and (2) one DCNN model identifying the direction (left vs. READ MORE

  5. 19. A numerical comparison of the thermoacoustics for different equivalence ratios for n-dodecane using LES

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Björn Jarfors; [2023]
    Keywords : Computational Fluid Dynamics; Bluff-body stabilised flames; Large Eddy Simulation; Thermoacoustics; Acoustics; NEUMANN Project; Jet engines; Aero engines; Airplanes; Combustion; Numerics; Technology and Engineering;

    Abstract : Klimatförändringarna påverkar vår värld och det behövs ett mer hållbart samhälle. Flygindustrin är i behov av förändring, men flygmotorer är mycket komplexa och tar tid att utveckla. Termoakustiska instabiliteter har kraften att förstöra en motor, men också att minska miljöpåverkan. READ MORE

  6. 20. Near Field millimeter Wave Antenna Measurements

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Bharath Manjunatha; [2023]
    Keywords : Antenna Pattern; Near field to far field; Planar Scanning; Probe Compensation; Active Antenna; Technology and Engineering;

    Abstract : In the real world, understanding an antenna's radiation pattern is crucial for its proper utilization. Typically, antennas are tested in the far-field region, where the radiation lobes are fully developed and phase errors are less than pi/8. READ MORE
