1. Application of Fourier Transforms to time-resolved ambient pressure spectroscopy operando studies of CO oxidation over Pt(111)
Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/SynkrotronljusfysikSammanfattning : 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. LÄS MER
2. A quantitative study of Swedish high school L2 learners' receptive knowledge of English lexical collocations
Kandidat-uppsats, Lunds universitet/EngelskaSammanfattning : 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.

3. Form-focused or meaning-focused? : Grammar tasks in EFL textbooks for English 5 in upper secondary school
Uppsats för yrkesexamina på avancerad nivå, Karlstads universitetSammanfattning : 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.

4. Digitally Controlled Oscillator Topologies for mm-Wave Pulsed Coherent Radar
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : 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. LÄS MER
5. Misfire Detection in Heavy Duty Diesel Engines Using Knock Sensors
Master-uppsats, Linköpings universitet/FordonssystemSammanfattning : 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. LÄS MER
