16. Development of Laser-Induced Fluorescence for Precombustion Diagnostics in Spark-Ignition Engines
Sammanfattning : Motivated by a desire to understand and optimize combustion in spark-ignition (SI) engines, laser techniques have been developed for measurement of fuel and residual gas, respectively, in the precombustion mixture of an operating SI engine. The primary objective was to obtain two-dimensional, quantitative data in the vicinity of the spark gap at the time of ignition. LÄS MER
17. Ultrahigh-Voltage Silicon Carbide Device Performance, Requirements, and Limitations in High-Power Applications
Sammanfattning : The increased awareness of the on-going climate change accelerates the electric energy system transformation from fossil-fueled power sources towards systems with larger portions of renewable energy sources. Moreover, the grid infrastructure requires reinforcements to cope with increasing electrical energy demand. LÄS MER
18. Aspects of probabalistic serviceability limit state design of dry deep mixing
Sammanfattning : An expanding population and increased need for infrastructure increasingly necessitate construction on surfaces with poor soil conditions. To facilitate the construction of buildings, roads and railroads in areas with poor soil conditions, these areas are often improved by means of foundation engineering. LÄS MER
19. School-age outcomes of children born at the limit of viability : a Swedish national prospective follow-up study at 10 to 12 years
Sammanfattning : Background/Aim: During the past two decades, major advances in maternal-fetal medicine, neonatology, and the development of regionalized perinatal care have resulted in dramatic increases in survival rates, by more than 60%, of extremely immature (EI) infants born at less than 26 completed weeks of gestation, creating a new infant population. Studies of school-age outcomes in children with an extremely low birth weight of < 1000 g, born in the1980s, indicated that these children had a substantially high prevalence of low-severity neuropsychological deficits, behavioral problems, and difficulties at school.

20. Precision Standard Model Phenomenology for High Energy Processes
Sammanfattning : The present status of particle physics is that the Standard Model has been completed with the discovery of theHiggs boson in 2012, but there is a multitude of phenomena in nature which is not accounted for by this model.Researchers are investigating possibilities for detecting new physics at the current particle physics facilities, withthe Large Hadron Collider (LHC) at the frontier.
