  1. 6. Magnetic field separation for current prediction in three-phase systems : Regression-based current prediction

    University essay from Mälardalens universitet/Akademin för innovation, design och teknik

    Author : Sara Lenman; Sofia Blaad; [2023]
    Keywords : Alternating Current; Crosstalk Separation; Magnetic field sensors; Regression; Sensor technology; Three-phase system;

    Abstract : Current controls the motion of a manipulator. The manipulators at ABB are powered by a three-phase alternating current system where shunt resistors are utilised to measure the current to the motors. Magnetic field sensors are instead investigated to eliminate issues with power losses, the number of components and the cost of the shunt resistors. READ MORE

  3. 7. Digital Front End Algorithms for Sub-Band Full Duplex

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Midhat Rizvi; Khaled Al-Khateeb; [2023]
    Keywords : Adjacent Channel Leakage Ratio; Bit Error Rate; Clipping and Filtering; Crest Factor Reduction; Digital front end; Digital Pre-Distortion Error Vector Magnitude; Frequency Division Duplex; Power Amplifier; Peak to Average Power Ratio; Peak Cancellation Crest Factor Reduction; Sub Band Full Duplex; Self-Interference Cancellation; Signal-to-Interference Noise Ratio; Signal-to-Noise Ratio; Turbo Clipping; Time Division Duplex; Technology and Engineering;

    Abstract : Sub-band full duplex is a new communication scheme technology, where a single frequency band is partitioned into sub-bands for downlink (DL) and up-link(UL) transmissions, and both can take place simultaneously. The idea behind the sub-band full duplex development is to improve the throughput, and coverage and reduce the latency of the UL communication by allowing the UL reception during the DL transmission.

  4. 8. Assisted GNSS Positioning using State Space Corrections

    University essay from Linköpings universitet/Institutionen för systemteknik

    Author : Oskar Philipsson; [2023]
    Keywords : positioning; GNSS; SSR; EKF; sensor fusion;

    Abstract : Classical GNSS based positioning has accuracy limitations due to many sources oferror. The error sources range from clock errors and orbit errors toerrors due to variations in atmospheric propagation delays. One way to improve GNSSpositioning is to generate real time corrections using a GNSS reference network. READ MORE

  5. 9. Transverse Momentum Spectra in pp collisions (\sqrt{s}\) = 7 TeV and \(\sqrt{s}\) = 13 TeV in ALICE

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Author : Andreas Stokkeland; [2023]
    Keywords : Multiplicity; Multiplicity classes; Soft interactions; Quark Gluon Plasma; QGP; transverse momentum; p_T; Chi-squared; fits; fit functions; Levy; Lévy; Exponential; BGBW; Boltzmann-Gibbs blast-wave; Fermi-Dirac; Bose-Einstein; Boltzmann; pion; kaon; proton; transverse momentum spectra; p_T spectra; surface velocity; Minimum Bias; MB; Physics and Astronomy;

    Abstract : In this project particle production as a function of transverse momentum (\(p_{\rm T}\)) in proton-proton collisions at a center-of-mass energy (\(\sqrt{s}\)) of 7 TeV and 13 TeV has been studied. The transverse momentum is interesting to study since it reflects momentum created in the collision (before the collision, all momentum is in the beam - going in a longitudinal direction) and therefore gives information on the collision dynamics.

  6. 10. Implementing SAE Techniques to Predict Global Spectacles Needs

    University essay from Högskolan Dalarna/Institutionen för information och teknik

    Author : Yuxue Zhang; [2023]
    Keywords : small area estimation; area-level model; empirical best linear unbiased prediction EBLUP ; generalized linear mixed models; Conditional Autoregressive; spatial correlation; spectacle needs; assistive products; auxiliary data; hglm; relative standard error; simulation;

    Abstract : This study delves into the application of Small Area Estimation (SAE) techniques to enhance the accuracy of predicting global needs for assistive spectacles. By leveraging the power of SAE, the research undertakes a comprehensive exploration, employing arange of predictive models including Linear Regression (LR), Empirical Best Linear Unbiased Prediction (EBLUP), hglm (from R package) with Conditional Autoregressive (CAR), and Generalized Linear Mixed Models (GLMM).
