1. 6. A hashing algorithm based on a one-way function in the symmetric group Sn

   University essay from Linnéuniversitetet/Institutionen för matematik (MA)

   Author : Adrian Perez Keilty; [2022]
   Keywords : cryptography; hashing; symmetric group; one way function;

   Abstract : We have found an operation between permutations in the symmetric group Sn upon which we have experimentally derived results that can be linked to desirable properties in cryptography, mainly in the domain of one-way functions. From it, we have implemented a beta version of an algorithm for a hashing function by exploiting the operation’s low computational cost for speed and its properties for security. READ MORE

3. 7. A comparative study of nature-inspired metaheuristic algorithms on sustainable road network planning

   University essay from Stockholms universitet/Institutionen för data- och systemvetenskap

   Author : Mohammed Luqman; [2022]
   Keywords : sustainable; road network; optimization; metaheuristic; global warming;

   Abstract : Global warming is a serious threat to the existence of human life on earth. Greenhouse gas emission is the major cause of global warming. Carbon dioxide is the major greenhouse gas emitted due to human activity. Road transport accounts for 15% of CO2 emissions worldwide. READ MORE

4. 8. A unified view of a family of soliton equations related to spin Calogero-Moser systems

   University essay from KTH/Fysik

   Author : Anton Ottosson; [2022]
   Keywords : Soliton equations; Solitons; Integrable systems; Spin Calogero-Moser systems; Exact solutions; Benjamin-Ono-type equations; Solitonekvationer; Solitoner; Integrerbara system; sCM-system; Exakta lösningar; Ekvationer av Benjamin-Ono-typ;

   Abstract : We study the interconnections between the spin Benjamin-Ono (sBO) and half-wave maps (HWM) equations, a pair of nonlinear partial integro-differential equations that have recently been found to permit multi-soliton solutions, where the time evolution of the constituent solitons can be described in terms of the well-known, completely integrable, spin Calogero-Moser (sCM) system. By considering a symmetry transformation of the sCM dynamics we are led to introduce a scale parameter into the sBO equation, yielding what we call the rescaled sBO (rsBO) equation, which has both the sBO and HWM equations as special cases.

5. 9. Conservative Discontinuous Cut Finite Element Methods: Convection-Diffusion Problems in Evolving Bulk-Interface Domains

   University essay from KTH/Matematik (Inst.)

   Author : Sebastian Myrbäck; [2022]
   Keywords : numerical analysis; mathematical modeling; convection-diffusion equation; partial differential equation; unfitted method; CutFEM; finite element method; discontinuous Galerkin method; numerisk analys; matematisk modellering; konvektions-diffusionsekvationer; partiella differentialekvationer; finita elementmetoden; diskontinuerliga Galerkinmetoden;

   Abstract : This work entails studying unfitted finite element discretizations for convection-diffusion equations in domains that evolve in time. In particular, these partial differential equations model the evolution of the concentration of soluble surfactants in bulk-interface domains. READ MORE

6. 10. Bieberbach's Theorem, Normal Families and Approximation by Single-Slit Maps

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

   Author : Robin Runyeon Odeberg; [2022]
   Keywords : complex analysis; Bieberbach s theorem; Bieberbach inequality; de Branges theorem; single-slit maps; univalent functions; normal families; Mathematics and Statistics;

   Abstract : The main purpose of this thesis is to prove the Bieberbach inequality using Grönwall’s area theorem, and discuss some consequences of the Montel’s theorem and Carathéodroty convergence theorem regarding single-slit maps, which is essential to the proof of de Branges’ theorem....
