1. 6. Longitudinal Group Sequential Testing

   University essay from Uppsala universitet/Statistiska institutionen

   Author : Emil Lanzén; [2023]
   Keywords : ;

   Abstract : Sequential testing is used in clinical trials and online experiments to terminate trials early if there is sufficient evidence of a treatment effect, reducing the subjects’ exposure to potentially harmful treatments. However, incomplete follow-up of trial subjects can lead to biased estimation of the treatment effect. READ MORE

3. 7. Real time estimations of kLa and viscosity in a fermentation pilot plant

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Arvid Norberg; [2022]
   Keywords : Oxygen transfer; Viscosity; Fermentation; Biotechnology; Direct method; kLa; OUR; DO; Online monitoring; Soft sensor; Fungus; Fungal fermentation; A. oryzae; A. niger; Herschel-Bulkley; Power law; Shear thinning; Novozymes; Enzymes; Technology and Engineering;

   Abstract : Fermentation is a process that utilizes live microorganisms to produce different biological products such as enzymes. The oxygen mass transfer rate is often the limiting factor in aerobic fermentations and thereby an important process parameter. READ MORE

4. 8. Modeling and Control of a PMSM Operating in Low Speeds

   University essay from Linköpings universitet/Fordonssystem

   Author : Robin Helsing; Tobias Sanchez; [2022]
   Keywords : PMSM; BLDC; low speed; EKF; UKF; MPC; Extended Kalman Filter; Unscented Kalman Filter; PI; Control; FOC;

   Abstract : A permanent magnet synchronous motor is a type of motor that is used in several different application areas, not least in an autonomous robots where it is the motor that drives the wheels. Today, many actors choose simulation as a tool to save money and time when product tests are performed. READ MORE

5. 9. Localization For AutonomousDriving using Statistical Filtering : A GPS aided navigation approach with EKF and UKF

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Devrat Singh; [2022]
   Keywords : Land Vehicle Localization; Sensor Fusion; GNSS-INS Fusion; UKF; EKF;

   Abstract : A critical requirement for safe autonomous driving is to have an accurate state estimate of thevehicle. One of the most ubiquitous yet reliable ways for this task is through the integrationof the onboard Inertial Navigation System (INS) and the Global Navigation Satellite System(GNSS). READ MORE

6. 10. Exploiting the Overtones in Online Localization of Sound Sources

   University essay from Lunds universitet/Matematisk statistik

   Author : David Sundström; [2022]
   Keywords : Multi-pitch estimation; localization; block sparsity; sparse recursive least squares; online estimation; ADMM; adaptive dictionary; Mathematics and Statistics;

   Abstract : Localization of multiple sound sources from a microphone array is a challenging task that has been a research topic for decades. The challenges stem from the diversity of acoustic contexts due to reverberation and disturbances. READ MORE
