Reactivity controlled compression ignition (RCCI) engines suffer from low thermal efficiency at low loads due to the high hydrocarbon and carbon monoxide emissions. Correspondingly, a direct dual fuel stratification (DDFS) combustion mode is investigated by directly injecting methanol and diesel into cylinder. Multi-objective optimization and detailed comparison are first conducted for the two eng
Objectives: Coronary heart disease (CHD) is a leading cause of death globally, commonly through sudden cardiac death. Cardiac arrest of cardiac origin (CA) is associated with a poor prognosis and there is a great need for risk assessment and intensified preventive actions. In this study we aim to assess if a genetic risk score for CHD, composed of 50 common CHD susceptibility variants (GRS), predi
This paper presents a study where a 3D motion-capture animated ‘virtual speaker’ is compared to a video of a real speaker with regards to how it facilitates children's speech comprehension of narratives in background multitalker babble noise. As secondary measures, children self-assess the listening- and attentional effort demanded by the task, and associates words describing positive or negative
Society faces the double challenge of increasing biomass production to meet the future demands for food, materials and bioenergy, while addressing negative impacts of current (and future) land use. In the discourse, land use change (LUC) has often been considered as negative, referring to impacts of deforestation and expansion of biomass plantations. However, strategic establishment of suitable pe
Sex chromosomes have evolved from the same autosomes multiple times across vertebrates, suggesting that selection for recombination suppression has acted repeatedly and independently on certain genetic backgrounds. Here, we perform comparative genomics of a bird clade (larks and their sister lineage; Alaudidae and Panuridae) where multiple autosome-sex chromosome fusions appear to have formed expa
Det finns många fördelar med att låta studenter vid högre utbildning gruppvis genomföra projektarbete med öppna frågeställningar. Det finns emellertid problem med att sätta individuella betyg i en kurs som till stor del examineras genom det gruppvisa projektarbetet. I kursen EEMA01 Medicinteknisk design ges valet av undervisningsform naturligt av lärandemålens karaktär men betygssättningen böravsp
A large portion of the PhD education in Sweden is dedicated to courses. This made it interesting to explore potential course supervision challenges in the PhD programme. A multiple-case study was conducted to identify such challenges and explore how these are perceived by students and supervisors at the Faculty of Engineering of Lund University. By interviewing students and supervisors in five dif
We developed a pebble-driven core accretion model to study the formation and evolution of planets around stars in the stellar mass range of 0.08 M⊙-1 M⊙. By Monte Carlo sampling of the initial conditions, the growth and migration of a large number of individual protoplanetary embryos were simulated in a population synthesis manner. We tested two hypotheses for the birth locations of embryos: at th
This study focuses on the assessment and selection of applicants for doctoral positions. The empirical data was gathered through a survey among faculty staff at Lund University, Sweden. The findings are also contrasted against the literature within the subject area, which is surprisingly scarce. One interesting finding of the survey is the frequent use of interviews and infrequent use of other ass

Engineering education among children has the potential to spark their interest in technical subjects, overcome gender imbalances within the field, and empower young people with the tools to make positive changes in their communities. However, it can be difficult to integrate into existing school curricula, especially when resources are constrained.Here I present a one-year case study conducted in
Universitetskanslerämbetet (UKÄ) ställer numera krav på svenska lärosäten att vi ska utvärdera oss själva. Vi på LTH bör då gemensamt försöka hitta sätt att uppfylla UKÄs krav som även ger de verktyg vi själva behöver för att förbättra våra utbildningars kvalitét.Hur tar vi reda på våra utbildningars styrkor och svagheter och vad vi kan göra för att förbättra dem ytterligare? Ett sätt är att under
För att lära sig programmera måste studenterna själva vara aktiva och öva programmering på dator. Med ett omfattande kursinnehåll går det av resursskälinte att göra all nödvändig övning obligatorisk därför har vi digitaliserat övningsuppgifter som tidigare varit på papper i ett försök att få studenterna att göra fler övningar på med en mer aktiv approach.Försöken har mottagits väl och en majoritet
Även om det är ytterst få av den undervisande personalen på Lunds tekniska högskola som medvetet skulle göra skillnad på kvinnliga respektive manliga studenter så förekommer det ändå. Det finns alltid en risk att undermedvetet ge fördelar/nackdelar av olika slag till olika grupper av studenter. För att undersöka detta gjordes en kvantitativ bedömning av kommunikationen mellan olika studentgrupper
