1. 1. Power System Oscillations - Detection, Estimation and Control

   Författare :Morten Hemmingsson; Industriell elektroteknik och automation; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik; oscillation; power system; damping; power swing; distance protection; detection; estimation; real-time; reactive co-variation; control; Electrical engineering; load modulation; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

   Sammanfattning : The topic of this thesis is the electro-mechanical oscillations which to some extent always are present in a power system. The demand of electric power is ever increasing. At the same time, the tolerance of disruptions in the power supply is decreasing. LÄS MER

3. 2. Evaluating and optimizing surveillance and response strategies for malaria elimination in the Asia Pacific region

   Författare :Chris Cotter; Andreas Mårtensson; Arantxa Roca-Feltrer; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; malaria elimination; surveillance and response; reactive case detection; sociobehavorial; reactive drug administration; molecular diagnostics; microsatellite genotyping; Plasmodium vivax; low transmission;

   Sammanfattning : Malaria case investigation and reactive case detection (RACD) activities are widely implemented in low transmission settings to identify additional malaria infections and gather surveillance information, but with varying degrees of success. Challenges in conducting RACD include poor diagnostic sensitivity (particularly for low density and asymptomatic infections), knowledge gaps among those conducting RACD, financial and resource constraints, and operational and logistical difficulties.

4. 3. Failure Monitoring and Asset Condition Assessment in Water Supply Systems

   Författare :Dalius Misiunas; Industriell elektroteknik och automation; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mechanical engineering; reglerteknik; robotteknik; Automatiska system; Water supply; failure; detection; monitoring; location; bursts; hydraulics; leakage; asset management; condition assessment; pipelines; pipe networks; Automation; control engineering; robotics; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik;

   Sammanfattning : In this thesis, different aspects of failure management in urban water supply systems are discussed. As assets are getting older, the number of pipe failures is increasing and an efficient failure management strategy becomes important. LÄS MER

5. 4. Data analytics for weak spot detection in power distribution grids

   Författare :Hassan Mashad Nemati; Sławomir Nowaczyk; Anita Pinheiro Sant'Anna; Math Bollen; Högskolan i Halmstad; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : This research aims to develop data-driven methods that extract information from the available data in distribution grids for detecting weak spots, including the components with degraded reliability and areas with power quality problems. The results enable power distribution companies to change from reactive maintenance to predictive maintenance by deriving benefits from available data. LÄS MER

7. 5. Type-specific human papillomavirus antibodies : detection, characterization and application in seroepidemiology

   Författare :Zhaohui Wang; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :antagonism; antibody; capsids; cervical carcinoma; CIN; epidemiology; HPV; isotype; neutralizing epitope; PCR; STDs; trends over time; VLPs;

   Sammanfattning : Background: Human Papillomavirus (HPV) is a sexually transmitted DNA virus that causes several human cancers, notably cervical and other anogenital cancers. The antibody response to this virus is of interest both because knowledge of the antigenic structures that induce protective immunity forms the basis for prophylactic vaccine development and because it forms the basis of seroepidemiology, the method of choice for studies of HPV infectivity, of HPV spread in populations and of cancer risks following HPV exposure.
