  1. 1. Application of Fourier Transforms to time-resolved ambient pressure spectroscopy operando studies of CO oxidation over Pt(111)

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Author : Grigore-Leon Ratiu; [2024]
    Keywords : Physics and Astronomy;

    Abstract : The study of heterogeneous catalysis has important implications in increasing the efficiency of industrial processes and in reducing the emissions of greenhouse gases from sources such as automobiles. A reaction with high industrial relevance is the oxidation of CO on noble metal catalysts. READ MORE

  3. 2. A quantitative study of Swedish high school L2 learners' receptive knowledge of English lexical collocations

    University essay from Lunds universitet/Engelska

    Author : Louise Frifelt; [2024]
    Keywords : Collocations; Multi-word units; Formulaic language; Second language acquisition; Languages and Literatures;

    Abstract : This paper investigates receptive knowledge of English lexical collocations among Swedish high school students. The study tests the claim that L2 (second language) learners of English have a low level of collocational competence and tend to recognise high-frequent collocations more than low-frequent since the former have been encountered more.

  4. 3. 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.

  5. 4. Digitally Controlled Oscillator Topologies for mm-Wave Pulsed Coherent Radar

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

    Author : Klas Junskog; [2023]
    Keywords : oscillators; mm-wave; radar; Technology and Engineering;

    Abstract : The advancement of future generations of wireless communication and radar sensing warrants the need for mm-wave digitally controlled oscillators (DCOs) with high-frequency trade-offs in consideration. The purpose of this project is to investigate DCO topologies inspired from scientific literature. READ MORE

  6. 5. Misfire Detection in Heavy Duty Diesel Engines Using Knock Sensors

    University essay from Linköpings universitet/Fordonssystem

    Author : Carl Sjöstedt; [2023]
    Keywords : ICE; combustion engine; combustion engines; Scania; diesel; knock; knock sensor; knock sensors; misfire; misfire detection;

    Abstract : In this thesis the possibility of using knock sensors for misfire detection in heavy duty diesel engines is investigated. This is of great interest due to many emission legislations getting stricter, especially in the US where robust misfire detection is mandatory for these types of engines. READ MORE
