1. 1. Multitemporal Remote Sensing for Urban Mapping using KTH-SEG and KTH-Pavia Urban Extractor

   Författare :Alexander Jacob; Yifang Ban; Paolo Gamba; Francesca Bovolo; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; KTH-SEG; ASAR; HJ-1B; Urban Land Cover Mapping; OBIA; Segmentation; Image Classification; KTH-Pavia Urban Extractor; Urban Extent; Geodesy and Geoinformatics; Geodesi och geoinformatik;

   Sammanfattning : The objective of this licentiate thesis is to develop novel algorithms and improve existing methods for urban land cover mapping and urban extent extraction using multi-temporal remote sensing imagery. Past studies have demonstrated that synthetic aperture radar (SAR) have very good properties for the analysis of urban areas, the synergy of SAR and optical data is advantageous for various applications.

3. 2. Change Detection Using Multitemporal SAR Images

   Författare :Osama Yousif; Yifang Ban; Lorenzo Bruzzones; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Change detection; ENVISAT ASAR; ERS-2 SAR; image denoising; Kittler-Illingworth algorithm; MAP-MRF classifier; modified ratio; multitemporal SAR images; nonlocal means NLM ; SAR speckle; urbanization;

   Sammanfattning : Multitemporal SAR images have been used successfully for the detection of different types of environmental changes. The detection of urban change using SAR images is complicated due to the special characteristics of SAR images—for example, the existence of speckle and the complex mixture of the urban environment.

5. 4. Dynamics of Resistant Plasmodium falciparum Parasites

   Författare :Nizar Enweji; Göte Swedberg; Anna Färnert; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Molekylär genetik; Molecular Genetics;

   Sammanfattning : Persistence of drug resistant Plasmodium falciparum is a major problem to management and control malaria in endemic areas. The focus of this thesis was to study the dynamics of resistant P. falciparum parasites. LÄS MER

7. 5. Factors Influencing Evolution to Antimalarial Drug Resistance in Plasmodium falciparum in Sudan and The Gambia

   Författare :Amany Kheir; Göte Swedberg; Susanne Kerje; Hamza Babiker; Staffan Svärd; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cross-mating; fitness; microsatellite haplotypes; mosquito infectivity; Infectious diseases; Infektionssjukdomar; Molekylär genetik; Molecular Genetics;

   Sammanfattning : Drug resistance is a major obstacle to management and control of malaria and currently progressing at a rapid rate across Africa. This thesis has examined factors influencing evolution of resistant P. falciparum at two sites in Africa, including parasite migration, cross mating and fitness cost of resistance. LÄS MER
