  1. 6. Multi-Agent Mission Planning and Execution for Small Autonomous Underwater Vehicles

    Författare :Özer Özkahraman; Petter Ögren; João Tasso de Figueiredo Borges de Sousa; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Underwater vehicles; collaborative; robotics; auv; navigation; coverage; search; slam; graph-slam; communication; control barrier functions; control; swarms; caging; capture; Datalogi; Computer Science;

    Sammanfattning : Our planet is mostly covered in water, most of it still unexplored.In order to understand our environment better, oceanographers have been mapping and monitoring these waters using ship-mounted sensors and wired vehicles with limited range compared to the vastness of the oceans.

  3. 7. Iodine status and iodine pool an a small community in western Sweden

    Författare :Mille Milakovic; Göteborgs universitet; []
    Nyckelord :goitre; thyroid volume; ultrasonography; urinary iodine; TpoAb; TSH; iodine supplementation; radioiodine uptake; scintigraphy; XRF;

    Sammanfattning : Iodine is essential in the synthesis of the vital hormones of the thyroid gland. On a worldwide basis, iodine deficiency is the global most important cause of thyroid disease. LÄS MER

  4. 8. Small-Scale Sample Handling for Studies of Liquid Crystals and Lipid-Based Soft Matter

    Författare :Gabriel Ohlsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fluorescence microscopy; nanocell; Microfluidics; aquaporins; liquid crystals; membrane transport; phase transitions; QCM-D; soft matter; lipid bilayer;

    Sammanfattning : In the field of sensing in general and biosensing in particular, there is a growing need for integratingminiaturised senor elements in microfluidic systems. The advantages are several, some of which being that the consumption of, often very expensive, sample material can be reduced; sampleexchange can be optimized; sensor performance in terms of detection limits can be improved and phenomena occurring on a very small, and even single-molecule, scale can be studied.

  5. 9. Atrial fibrillation in aging; methodological aspects and the relation to dementia and cerebral vascular disease

    Författare :Lina Rydén; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; atrial fibrillation; dementia; stroke; silent brain infarcts; white matter hyperintensity; cerebral microbleed; small vessel disease; epidemiology;

    Sammanfattning : Emerging evidence suggest an increased risk of dementia in individuals with atrial fibrillation (AF). However, until recently, few studies have investigated the relation between AF and dementia taking both prevalent and incident stroke into account. LÄS MER

  7. 10. Development of analytical methods for the determination of the small molecule component of complex biological systems

    Författare :Kristian Pirttilä; Mikael Hedeland; Curt Pettersson; Torbjörn Arvidsson; Thomas Moritz; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metabolomics; data processing; peak characterization; algorithm; multivariate data analysis; chromatography; sequential columns; HILIC; RPLC; liquid chromatography; mass spectrometry; LC; MS; noise-induced hearing loss; NIHL; guinea pig; perilymph; method development; validation; R; C ; Analytical Pharmaceutical Chemistry; Analytisk farmaceutisk kemi;

    Sammanfattning : The research field of untargeted metabolomics aims to determine the relative abundance of all small metabolites in a biological system in order to find biomarkers or make biological inference with regards to the internal or external stimuli. This is no trivial aim, as the small metabolites are both vast in numbers and extremely diverse in their chemical properties. LÄS MER
