  1. 16. Implementation and Comparative Analysis of Head-Related and Binaural Room Impulse Response in a Mid-Side Decomposition

    University essay from KTH/Teknisk akustik

    Author : Jonathan Ling; [2023]
    Keywords : Master’s Thesis; Spatial audio; Sound Externalisation; Binaural recording; Headphones; Mid-Side Processing; Masteruppsats; Rumsligt Ljud; Ljud-externalisation; Binaural Inspelning; Hörlurar; Mid-Sid processering;

    Abstract : This thesis aimed to clarify the essential factors involved in externalising audio over headphones. Extensive research was conducted, examining binaural cues and the latest advancements in the field. A novel approach was proposed, which applied HRIRs and BRIRs on a Mid-Side decomposition.

  3. 17. Moderling Acoustic Transmission in Towed Array Sonars : Computations of the coupled acoustic and elastic wave equations

    University essay from KTH/Matematik (Avd.)

    Author : Bill Claesson; [2023]
    Keywords : ;

    Abstract : This thesis presents a method of solving the Helmholtz equation coupled with the Navier-Cauchy equation over a cross section of a Towed Array Sonar (TAS) modeled as a simplified cylindrical shell. The purpose of solving these equations is to estimate the transfer function of the pressure between the outside boundary and a position inside the TAS. READ MORE

  4. 18. Form-focused or meaning-focused? : Grammar tasks in EFL textbooks for English 5 in upper secondary school

    University essay from Karlstads universitet

    Author : Angelica Eriksson; [2023]
    Keywords : form-focused; meaning-focused; instruction; grammar; tasks; CLT;

    Abstract : This paper investigates what role grammar plays, what grammatical content is included, and whether focus on form or meaning dominates in six EFL (English as a Foreign Language) textbooks for English 5. Through the methodology content analysis, the grammatical content is calculated, categorized, and analyzed with coding frames in three parts: form-focused instruction and grammar tasks and meaning-focused instruction and grammar tasks, context, and grammatical categories.

    Abstract : Massive multiple input multiple output - MIMO systems are a reality and modern communication systems rely upon this technology to cope with the increasing need for capacity and network usage. Antenna arrays are at the heart of the of the massive-MIMO system and are the enabling technology. READ MORE

  6. 20. ISAR Imaging Enhancement Without High-Resolution Ground Truth

    University essay from Linköpings universitet/Datorseende

    Author : Moltas Enåkander; [2023]
    Keywords : SAR; SAR Imaging; ISAR; ISAR Imaging; Machine learning; Convolutional neural network; CNN; neural network; Super resolution; Unsupervised learning;

    Abstract : In synthetic aperture radar (SAR) and inverse synthetic aperture radar (ISAR), an imaging radar emits electromagnetic waves of varying frequencies towards a target and the backscattered waves are collected. By either moving the radar antenna or rotating the target and combining the collected waves, a much longer synthetic aperture can be created. READ MORE
