2. 1. Radome Diagnostics: utilizing Source Reconstruction based on Surface Integral Representations

   Author : Kristin Persson; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nondestructive testing; source reconstruction; diagnostics; radome; phase reconstruction; insertion phase delay IPD ; equivalent surface currents;

   Abstract : In this thesis, an inverse source reconstruction method with great potential in radome diagnostics is presented. A radome is a cover that encloses an antenna in order to protect it from environmental influences. READ MORE

4. 2. Assessment of mobile radiometry data in radiological emergencies using Bayesian statistical methods

   Author : Antanas Bukartas; Malmö Medicinsk strålningsfysik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mobile gamma spectrometry; Gamma spectrometry; Orphan source; lost source; Ionizing radiation; Bayesian; Activity; position; activity density; reconstruction; UAV; car-borne;

   Abstract : Nuclear technology and the use of radiation sources have been extensively adopted in the modern world. Despite that, a number of radiological accidents, significantly affecting population and the environment, has happened. Few of the most known are accidents in Chernobyl and Fukushima nuclear power plants. READ MORE

5. 3. Unsupervised Segmentation of Head Tissues from Multi-Modal Magnetic Resonance Images: With Application to EEG Source Localization and Stroke Detection

   Author : Mahmood Qaiser; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stroke; EEG source localization; Image segmentation; reconstruction; magnetic resonance; brain;

   Abstract : The automated segmentation or labeling of individual tissues in magnetic resonance (MR) images of the human head is an essential first step in several biomedical applications. The resulting segmentation yields a patient-specific labeling of individual tissues that can be used to quantitatively characterize these tissues (e.g. READ MORE

6. 4. The Story Behind the News : Informal and Invisible Interactions between Journalists and Their Sources in Two Countries

   Author : Milda Malling; Lars Nord; Gunnar Nygren; Mattias Ekman; Mittuniversitetet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; journalist; source; relationships; process model of journalistic roles; professional role; informality; unattributed sources; news beat; politics; social tie; trust; reconstruction interview; Lithuania; Swden; political communication;

   Abstract : Journalists encounter some of their sources only episodically, while relationships with other sources involve several social contexts and roles. The political beat, where both reporters and sources have years of experience in the field and interact on regular basis, and where opinions can turn into news, is an arena where relationships and interactions play a special role.
