  1. 6. Optimal Multitaper Spectrograms

    University essay from Lunds universitet/Matematisk statistik

    Author : Markus Ydreskog; [2023]
    Keywords : Time-frequency analysis; Multitaper spectrogram; Optimization; Wigner distribution; Mathematics and Statistics;

    Abstract : Multitaper spectrograms have been proposed as a method of improving the spectrogram as a time-frequency representation (TFR). This thesis aimed to investigate both previously used and new methods for combining multitaper spectrograms of a Gaussian signal and a chirp. READ MORE

  2. 7. Reinforcement Learning for the Optimization of Explicit Runge-Kutta Method Parameters

    University essay from Lunds universitet/Matematik LTH; Lunds universitet/Matematik (naturvetenskapliga fakulteten); Lunds universitet/Matematikcentrum

    Author : Mélanie Fournier; [2023]
    Keywords : reinforcement learning; numerical analysis; Runge-Kutta; policy gradient; REINFORCE; Mathematics and Statistics;

    Abstract : Reinforcement learning is one of the three main paradigms in machine learning, which is increasingly used as a method to approach scientific problems. In this thesis, we introduce and use reinforcement learning to find the optimal parameters of a numerical solver. READ MORE

  3. 8. An Introduction to p-adic Analytic Groups

    University essay from Lunds universitet/Matematik LTH; Lunds universitet/Matematik (naturvetenskapliga fakulteten); Lunds universitet/Matematikcentrum

    Author : Frieder Selisko; [2023]
    Keywords : Mathematics and Statistics;

    Abstract : In this thesis we introduce the concept of a p-adic analytic pro-p group. To do so we discuss important theorems and concepts connected to more general types of groups, these include profinite groups, pro-p groups, powerful p-groups, powerful pro-p groups and uniform groups...

  4. 9. Zero Spectrum Subalgebras of K[x] Described by Higher Derivatives

    University essay from Lunds universitet/Matematik LTH

    Author : Erik Kennerland; [2023]
    Keywords : Algebra; Almost Monomial Subalgebra; Derivation; Lower Degree; Lower Semigroup; Subalgebra Spectrum; Truncation; Mathematics and Statistics;

    Abstract : Unital subalgebras of finite codimension in the polynomial ring $\mathbb{K}[x]$ are described by a finite number of so called subalgebra conditions over a finite set in $\mathbb{K}$ named the subalgebra spectrum. Restricting attention to subalgebras whose spectrum is the singleton $\{0\}$ reveals a rather well behaved class of subalgebras, called almost monomial from the fact that these contain an ideal consisting of all monomials above a certain degree.

  5. 10. Real-time Sound Analysis to Count Opening Cycles of Automatic Doors

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

    Author : Teodor Renman; Charlie Ringström; [2023]
    Keywords : Sound analysis; signal processing; event detection; MFCC; real-time; automatic door; embedded programming; stm32; microcontroller; Technology and Engineering;

    Abstract : Counting opening cycles on an automatic sliding door is of great interest for a company manufacturing doors, such as ASSA Abloy. These metrics could be used for consumer statistics or for door diagnostics. Counting opening cycles is seemingly trivial when there is access to the door’s internal diagnostics or having adequate sensors. READ MORE
