2. 1. Terrain Modelling with GIS for Tectonic Geomorphology : Numerical Methods and Applications

   Author : Gyözö Jordan; Ulf Qvarfort; Tsehaie Woldai; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; digital elevation model; digital terrain modelling; GIS; morphometry; tectonic geomorphology; Miljöteknik; Environmental engineering; Miljöteknik;

   Abstract : Analysis of digital elevation models (DEMs) by means of geomorphometry provides means of recognising fractures and characterising the morphotectonics of an area in a quantitative way. The objective of the thesis is to develop numerical methods and a consistent GIS methodology for tectonic geomorphology and apply it to test sites. READ MORE

4. 2. Development of a Detailed Geomorphological Mapping System and GIS Geodatabase in Sweden

   Author : Marcus Gustavsson; Else Kolstrup; Harry Seijmonsbergen; Ian S. Evans; Uppsala universitet; []
   Keywords : Physical geography and sedimentology; Geomorphology; Geomorphological map; GIS; Sweden; Naturgeografi och sedimentologi;

   Abstract : This thesis presents a method for detailed landscape presentation. The method incorporates both fieldwork-based comprehensive geomorphological description and digital data handling and thus contributes in filling the gap between traditional geomorphological mapping and modern geomorphological studies performed in Geographic Information Systems (GIS).

5. 3. Predictive Modelling of Aquatic Ecosystems at Different Scales using Mass Balances and GIS

   Author : Andreas Gyllenhammar; Lars Håkanson; Lars Brydsten; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; mass balance model; dynamic model; scales; marine fish farms; rainbow trout; nutrients; suspended particulate matter; phosphorus; nitrogen; GIS; basin delineation; regionalisation; coastal areas; aquatic foodweb; fishing quotas; Baltic Sea; Archipelago Sea; Okavango Delta; Geovetenskap; Earth sciences; Geovetenskap;

   Abstract : This thesis presents models applicable for aquatic ecosystems. Geographical Information Systems (GIS) form an important part of the thesis. The dynamic mass balance models focus on nutrient fluxes, biotic/abiotic interactions and operate on different temporal and spatial scales (site, local, regional and international). READ MORE

6. 4. Analytical tools and information-sharing methods supporting road safety organizations

   Author : Imad Abugessaisa; Erland Jungert; Kenneth Asp; Åke Sivertun; Josef Mikulik; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Visual data mining; STRADA; GLOBESAFE; Conceptual model; System thinking; Internet GIS; Computer science; Datavetenskap;

   Abstract : A prerequisite for improving road safety are reliable and consistent sources of information about traffic and accidents, which will help assess the prevailing situation and give a good indication of their severity. In many countries there is under-reporting of road accidents, deaths and injuries, no collection of data at all, or low quality of information. READ MORE

7. 5. Genetic genealogy and epidemiology of Francisella

   Author : Kerstin Svensson; Anders Johansson; Mats Forsman; Sam R. Telford III; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Francisella tularensis; tularemia; genotyping; epidemiology; GIS; Infectious diseases; Infektionssjukdomar; Infectious Diseases; infektionssjukdomar;

   Abstract : This thesis is about analyzing genetic differences among isolates of Francisella tularensis – the tularemia-causing bacterium. To elucidate how these bacterial isolates are related, and their geographical and genetic origins, I have developed typing assays for Francisella and used them to study the epidemiology of tularemia.
