1. Deposit formation in the grate-kiln process
Sammanfattning : Deposit formation in the grate-kiln process is a challenge for the iron ore pellet production industry. The deposits cause disturbances that affect the production capacity of the pelletizing plant. LÄS MER
2. Bilden och texten : En studie av ljusets och seendets pedagogik
Sammanfattning : The thesis deals with a reading tradition that can be traced to medieval times, a tradition in which images and text, intertwined, convey the message to the reader. The strength of the coupling between image and text has varied over time. Initially closely interconnected, the connections between image and text were later separated. LÄS MER
3. Skolplanschen : Argument i spänning mellan bild och text, perspektiv och kontext
Sammanfattning : This study reaches back to a reading tradition that can be traced to Antiquity and Medieval times; a reading tradition where images and text joined in a symbiosis conveyed the story to the reader. From initially being closely interconnected, the connections between image and text have separated, and the strength of the coupling between image and text has varied over time. LÄS MER
4. Dödsfall i Sverige till följd av brand : Omfattning och historiska trender
Sammanfattning : Ingen ska omkomma eller skadas svårt till följd av brand. Så lyder den nollvision som Myndigheten för Samhällsskydd och Beredskap har formulerat för brandskyddsområdet. Visionen ingår i en nationell strategi för att stärka brandskyddet för den enskilde och innehåller förutom vision tydliga mål. LÄS MER
5. Detecting Inclusions in a Silicone Rubber Phantom Using Standing Lamb Waves and Multiple Frequency Footprints
Sammanfattning : The thesis deals with one major question: is it possible, using one piezoelectric sensor/vibrator, to detect a hard inclusion in a silicone rubber phantom? The question was approached with an open mind and the task was subdivided into three clearly identifiable parts: characterization of the piezoelectric sensor/vibrator (paper I), creating a model of the visco-elastic properties of a tissue-like material (phantom) in contact with the sensor/vibrator (paper II), and to detect the presence of a hard inclusion in the phantom (paper III). All vibrations of the sensor/vibrator and phantom was modeled using a finite element method (FEM). LÄS MER
