1. 16. State- and Parameter Estimation for Spacecraft with Flexible Appendages using Unscented Kalman Filters

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Andrea Mosquera Alonso; [2019]
   Keywords : Estimation; flexibility; flexible spacecraft; spacecraft; kalman filter; unscented Kalman filter; spacecraft dynamics; flexible dynamics;

   Abstract : The problem of system identification for dynamic effects on spacecraft has become increasingly relevant with the surge of agile spacecraft, which must perform large amplitude maneuvers at high rates. Precise knowledge of the state of the spacecraft, as well as of the parameters characterizing its motion, is vital for the design of control algorithms enabling stabilization and pointing accuracy.

3. 17. Characterising copy number polymorphisms using next generation sequencing data

   University essay from Uppsala universitet/Institutionen för biologisk grundutbildning; Uppsala universitet/Institutionen för immunologi, genetik och patologi

   Author : Zhiwei Li; [2019]
   Keywords : structural variations; copy number variations; copy number polymorphisms; next generation sequencing; The Northern Sweden Population Health Study; Genome-wide association study;

   Abstract : We developed a pipeline to identify the copy number polymorphisms (CNPs) in the Northern Swedish population using whole genome sequencing (WGS) data. Two different methodologies were applied to discover CNPs in more than 1,000 individuals. READ MORE

4. 18. Navigation Strategies for Improved Positioning of Autonomous Vehicles

   University essay from Linköpings universitet/Reglerteknik

   Author : David Sandmark; [2019]
   Keywords : MPC; positioning; nonlinear; linear; approximation; error; navigation; control; improved; covariance;

   Abstract : This report proposes three algorithms using model predictive control (MPC) in order to improve the positioning accuracy of an unmanned vehicle. The developed algorithms succeed in reducing the uncertainty in position by allowing the vehicle to deviate from a planned path, and can also handle the presence of occluding objects. READ MORE

5. 19. Infinite-Dimensional Linear Stochastic Systems with Random Coefficients and Local Interactions

   University essay from Lunds universitet/Matematisk statistik

   Author : Henrik Bengtsson; [2018]
   Keywords : Stochastic processes; Local interaction; autoregressive random coefficients; probability the- ory.; Mathematics and Statistics;

   Abstract : In this thesis some results for a model that is a merge between the random coefficient autoregressive model of order one and a stochastic process with local interaction in time and space are presented. The first part of the thesis deals with some result from the random coefficient model. READ MORE

6. 20. Hedging malting barley : maximizing expected utility considering price, yield and quality risk

   University essay from SLU/Dept. of Economics

   Author : Torgil Andersson; [2018]
   Keywords : expected utility; futures contracts; hedging; malting barley; quadratic risk; programming; quality risk; risk management; risk preference;

   Abstract : Farmers are faced with situations with uncertain outcomes on a daily basis. Production risks stem from uncertainty about the performance of crops and the unpredictable nature of weather. Also, the markets for inputs and agricultural commodities affect the farm to a high degree. READ MORE
