  1. 1. The Riemann Zeta Function and Prime Numbers

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Oskar Rune; Linus Envall; [2023]
    Keywords : ;

    Abstract : This thesis is the result of a literature study regarding the relationship between the Riemann zeta function and prime numbers. We introduce the $\zeta$ function, discussing its properties. Then, starting from Riemann's original series, we derive the Euler product formula and functional equation for $\zeta$. READ MORE

  3. 2. Implementing the chirality-flow formalism for tree-level massless QCD in MadGraph

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Adam Warnerbring; [2023]
    Keywords : Theoretical physics; The chirality-flow formalism; Physics and Astronomy;

    Abstract : The chirality-flow formalism provides a simple but efficient way to rewrite and evaluate Feynman diagrams and has recently been shown to also optimize automated numerical scattering matrix element evaluations in massless tree-level QED. In this thesis we extend the numerical QED model to massless tree-level QCD in the MadGraph5_aMC@NLO framework. READ MORE

  4. 3. Generating Perturbative Solutions for Slowly Rotating Perfect Fluids Using the Hartle Scheme

    University essay from Umeå universitet/Institutionen för fysik

    Author : Elin Johansson; [2023]
    Keywords : ;

    Abstract : In this thesis, we study slowly rotating relativistic stars by modeling them as perfect fluids. The Hartle formalism is used to perturb a spherically symmetric static solution into slow rotation and the corresponding field equations to second order are presented. READ MORE

  5. 4. Improving the Accuracy of FFT-based GPGPU Ocean Surface Simulations

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Jacob Eriksson; Joakim Wingård; [2022-12-01]
    Keywords : computer graphics; 3D graphics; real-time rendering; Fourier transform; FFT; simulation; GPGPU; interactive; ocean wave spectrum; oceanography;

    Abstract : In this paper, we explore how the current state of the art in real-time ocean simulations can be improved in terms of simulation accuracy, while preserving performance. Current methods, both in academia and in the industry, simulate an ocean model in frequency space on the GPU, convert said model on an approximately frame-byframe basis to the spatial domain using the Fourier transform, and then read back the resulting heightfield to the CPU as input to the application’s physics engine.

  6. 5. The Efficiency of Good Software Practices : A Case Study on a Radar Meteor Analysis Software Rewrite

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

    Author : Kenneth Kullbrandt; [2022]
    Keywords : software practices; computer science; rewrite; refactor;

    Abstract : Software engineering as a profession has since early on in its conception been focused with how to best maximize the quality of software. Quality in this regard is both objectively measurable things (like speed, size, and cost) and less measurable things (like conciseness, elegance, and customer satisfaction). READ MORE
