  1. 1. Word Frequencies and Vocabulary Threshold Levels in EFL Textbooks. A Corpus Study

    University essay from Göteborgs universitet / Lärarutbildningsnämnden

    Author : Samantha Read; [2023-06-19]
    Keywords : Vocabulary; corpus; coursebooks; upper secondary; word frequencies; threshold levels;

    Abstract : A significant number of studies have identified inadequate vocabulary exposure in EFL coursebooks as a problem. However, few studies have been carried out in the Swedish context. READ MORE

  3. 2. Is the Echo English series relevant for advanced learners? : -A study on lexical character and recycling in two Swedish EFL textbooks for upper secondary school

    University essay from Örebro universitet/Institutionen för humaniora, utbildnings- och samhällsvetenskap

    Author : Magnus Ejnarsson; [2023]
    Keywords : Incidental learning; textbook analysis; recycling; pedagogy;

    Abstract : This study aims to provide additional research into how Swedish EFL textbooks support incidental vocabulary learning through reading texts, specifically for textbooks aimed at upper secondary school, expecting a greater emphasis on recycling mid- and low-frequency words. The study has investigated the lexical character of two textbooks, Echo English 5 and Echo English 7, as well as how they recycle lemmas and how well they recycle lemmas from the mid- and low-frequency bands.

  4. 3. Acoustic perception of Metal live performance in a multipurpose hall (Black Box) : A study into the influence of the acoustical quality of a Black Box regarding Metal live performance.

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Author : Sam Soliman; [2023]
    Keywords : Metal; room acoustics; influence; live performance; parameters; acoustics;

    Abstract : A study has been implemented regarding the acoustical characteristics of a black box and its influence on rock and metal music live performance. Objective acoustical measurements have been made as well as a subjective evaluation in form of a listening test. READ MORE

  5. 4. Cosmic Dust Detection by the Solar Orbiter Using Machine Learning

    University essay from Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

    Author : Joar Lönngren; Ludwig Tiston; [2023]
    Keywords : Machine Learning; Neural Network; Cosmic Dust; Solar Orbiter; Space Physics; Space Dust;

    Abstract : This project aims to investigate neural network systems as an effective tool for the in-space captured dust impact signal detection. Cosmic dust is the nanometre to micrometre fine-sized particles that exist in the interplanetary region. They originate from comets, asteroids, the planets and their moons and rings, or even the interstellar region. READ MORE

  6. 5. Simulation of low frequency acoustic waves in small rooms : An SBP-SAT approach to solving the time dependent acoustic wave equation in three dimensions

    University essay from

    Author : Alva Fährlin; Olle Edgren Schüllerqvist; [2023]
    Keywords : room acoustics; numerical methods; SBP; SAT; acoustic wave equation.;

    Abstract : Low frequency acoustic room behaviour can be approximated using numerical methods. Traditionally, music studio control rooms are built with complex geometries, making their eigenmodes difficult to predict mathematically. READ MORE
