22. Electromagnetic transitions and nuclear structure : radioactive decay and in-beam studies of coincident radiations
Sammanfattning : Nuclear spectroscopy studies including determination of spatial and time distributions of nuclear electromagnetic radiations have been performed in off- and on-line experiments. The following eight nuclei have been the subject of these studies 90Zr, 119Sb, 126Te, 160Dy, 180Hf, 184Pt and 195, 197T1. LÄS MER
23. Modeling of induction stirred ladles
Sammanfattning : Over the years numerous computational fluid dynamics models have been developed in order to study the fluid flow in gas and induction stirred ladles. These models are used to gain insight in the industrial processes used in ladle treatment of steel. A unified model of an induction stirred Ladle in two and three dimensions is presented. LÄS MER
24. Inversion and Joint Inversion of Electromagnetic and Potential Field Data
Sammanfattning : In this thesis, four inversion problems of different scale and difficulty are solved. Two of them are electromagnetic inverse problems. Two more are joint inversion problems of potential field data and other types of data. LÄS MER
25. Features and Origin of Electromagnetic Fields Generated by Lightning Flashes
Sammanfattning : Negative cloud-to-ground (CG) lightning flashes transport negative charge from cloud to ground. Negative ground flashes typically involve various processes identified as preliminary breakdown, stepped leader, return stroke, dart leader, dart-stepped leader, subsequent return stroke, and cloud activity between strokes, such as regular pulse trains and chaotic pulse trains.
