2. 6. Microwave Measurement Systems for In-line 3D Monitoring of Pharmaceutical Processes

   Author : Livia Cerullo; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; permittivity; moisture content; microcrystalline cellulose; Pharmaceutical processes; dispersive media; finite element method; microwave measurements;

   Abstract : The monitoring and understanding of pharmaceutical processes are important in order to achieve high-quality products at a low-production cost. The presence of water, e.g. as moisture content in the solid-state pharmaceutical material, is ofparticular interest and importance. READ MORE

4. 7. MEMS Interfaces for Bioanalysis Systems

   Author : Thomas Frisk; Göran Stemme; Andreas Hierlemann; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microfluidic interfacing; microfluidics; µTAS; sample transfer; biosensor; electronic nose; surface tension; quartz crystal microbalance; QCM; narcotics detection; Electronic measurement and instrumentation; Elektronisk mät- och apparatteknik;

   Abstract : This thesis deals with various aspects of using open microfluidic interfaces. Three specific areas of application are studied. The first is air-to-liquid interfacing in biosensors with possibilities for component inte­gration. A micromachined interface for airborne sample-to-liquid and droplet-to-liquid adsorption is discussed. READ MORE

5. 8. Track circuits’ robustness : Modeling, measurement and simulation

   Author : Emilio Rodriguez; Ajit Kumar Verma; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Track circuit; Relay; False positive signals; Signalling in railway; Modelling; Simulation; Testing; Robustness; Interoperability; Reliability; Railway Infrastructure; Drift och underhållsteknik; Operation and Maintenance Engineering;

   Abstract : In countries with rough weather conditions, frequent delays cause railway companies to waste time and money. Many of these delays are related to the train detection systems, as the old DC track circuits are still used in some countries, including Sweden, our case study. READ MORE

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

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

   Abstract : 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.

7. 10. Design of Functional Structures and Measurement Techniques for Electromagnetic Waves

   Author : Johan Lundgren; Teoretisk elektroteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; functional structures; frequency selective structures; polarization selectivity; metasurface; near-field measurements; antenna measurements; scattering measurement; power density; random media;

   Abstract : Electromagnetic fields exist all around us. Through evolution, nature has developed tools to interact and use these fields, where our eyes are a spectacular example. Humans have a long history of developing structures and objects of their own to alter and interact with these fields. READ MORE
