1. 11. Semi-Autonomous Navigation of Powered Wheelchairs : 2D/3D Sensing and Positioning Methods

   Författare :Cristian Vilar; Mattias O'Nils; Silvia Krug; Nicolas Ragot; Mittuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 3D object recognition; YOLO; YOLO-Tiny; 3DHOG; Histogram-of-Oriented-Gradients; ModelNet40; Feature descriptor; Intel RealSense; Depth camera; Wheelchair;

   Sammanfattning : Autonomous driving and assistance systems have become a reality for the automotive industry to improve driving safety in the car. Hence, the cars use a variety of sensors, cameras and image processing techniques to measure their surroundings and control their direction, braking and speed for obstacle avoidance or autonomously driving applications.

3. 12. Physicochemical and Biopharmaceutical Characterisation of Small Drug Molecules by Capillary Electrophoresis

   Författare :Eivor Örnskov; Staffan Folestad; Karin E. Markides; Morteza Khaledi; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; capillary electrophoresis CE ; micellar electrokinetic chromatography MEKC ; drug; liposome; microemulsion; coating; pKa; lipophilicity; multivariate analysis; molecular descriptor; hierarchical analysis; passiv absorption; Analytisk kemi; Analytical chemistry; Analytisk kemi;

   Sammanfattning : Capillary Electrophoresis (CE) was explored as a means for physicochemical and biopharmaceutical characterisation of small drug molecules. Special attention was paid to the characterisation of acid-base and lipophilic properties of drug compounds by analysing their migration behaviour in different CE systems. LÄS MER

4. 13. Enantiomeric Separations using Chiral Counter-Ions

   Författare :Jakob Haglöf; Curt Pettersson; Anders Karlsson; Jacques Crommen; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Capillary Electrophoresis; Chiral Counter-Ion; Divalent Dipeptide; Enantioselectivity; Electroosmosis; Chemometrics; Molecular Descriptor; Structure-Enantioselectivity Relationship; Pharmaceutical chemistry; Farmaceutisk kemi; Analytical Pharmaceutical Chemistry; Analytisk farmaceutisk kemi;

   Sammanfattning : This thesis describes the use of chiral counter-ions for the enantiomeric separation of amines in non-aqueous capillary electrophoresis. The investigations have been concentrated on studies of the influence, of the chiral counter-ion, the solvent, the electrolyte and the analyte, on the enantioselective separation. LÄS MER

5. 14. Residual generation for fault diagnosis

   Författare :Erik Frisk; Lars Nielsen; Linköpings universitet; []
   Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : The objective when supervising technical processes is to alarm an operator when a fault is detected and also identify one, or possibly a set of components, that may have been the cause of the alarm. Diagnosis is an expansive subject, partly due to the fact that nowadays, more applications have more embedded computing power and more available sensors than before. LÄS MER

7. 15. Networks and epidemics - impact of network structure on disease transmission

   Författare :Jenny Lennartsson; Uno Wennergren; Annie Jonsson; Meggan Craft; Högskolan i Skövde; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Natural sciences; Naturvetenskap;

   Sammanfattning : The spread of infectious diseases, between animals as well as between humans, is a topic often in focus. Outbreaks of diseases like for example foot-and-mouth disease, avian influenza, and swine influenza have in the last decades led to an increasing interest in modelling of infectious diseases since such models can be used to elucidate disease transmission and to evaluate the impact of different control strategies.
