  1. 36. 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. 37. Correction of Radial Sampling Trajectories by Modeling Nominal Gradient Waveforms and Convolving with Gradient Impulse Response Function

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Max Kim; Adham Belbaisi; [2019]
    Keywords : Magnetic resonance imaging; MRI; gradient waveforms; radial sampling; gradient imperfections; gradient impulse response function; GIRF; Magnetresonanstomografi; MRI; gradient vågformer; radiell sampling; gradient imperfektioner; gradient impulsresponsfunktion; GIRF;

    Abstract : There are several reasons for using non-Cartesian k-space sampling methods in Magnetic Resonance Imaging (MRI). Such a method is radial sampling, which includes the advantage of continuous coverage of the k-space center which results in higher robustness to motion. READ MORE

  4. 38. How is feed-related behaviour in growing pigs affected by total mixed ration feed with intensively treated silage?

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Sara Holmström; [2019]
    Keywords : pig behaviour; grass-clover silage; total mixed ration; social interactions; nutrient utilization;

    Abstract : In Nordic countries, roughage e.g. silage from ley crops is mainly provided in the daily feed rations to pigs within organic production systems. Grass-clover silage brings multiple advantages in letting pigs perform natural behaviours and reduces aggressive social interactions. READ MORE

  5. 39. Time-frequency analysis of THz-time domain spectroscopy data

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : Hugo Laurell; [2018]
    Keywords : ;

    Abstract : This text investigates THz-TDS signals in the time-frequency domain. Addi- tionally this text discusses the prospects of using time-frequency analysis to alleviate distortion in THz spectrographic characterizations induced by back- reflections in the free space electro optic sampling used in the THz time-domain spectroscopy detection scheme.

  6. 40. Development of an Online Monitoring and Sampling Scheme for Recombinant Protein Production

    University essay from Lunds universitet/Bioteknik (master)

    Author : Louise Bengtsson; [2018]
    Keywords : Biotechnology; Biochemistry; Online Sampling; Online Monitoring; Fermentation; Bioteknik; Technology and Engineering;

    Abstract : During the past few years the focus on bioprocess monitoring and control has increased. An area still under intensive development is the sampling methods for efficient and rapid analysis during fermentations. READ MORE
