1. 1. Dynamic simulation and 3D visualization of a floating tilted counter-rotating vertical axis offshore wind turbine

   University essay from

   Author : Lovisa Jonsson; Alexander Hedene; Klara Österling; [2023]
   Keywords : Wind turbine; Offshore; VAWT; CRVT; Simulation; Visualization; MATLAB; Dynamics;

   Abstract : The growing global demand for clean energy is critical, and wind power plays a crucial role in addressing this need. The increasing demand is driving advancements in the field of offshore wind power and one promising innovation is the counter-rotating vertical axis turbines (CRVT), specifically designed for floating wind power installations.

3. 2. Transportation Study of Release from a Space Elevator to Cislunar Space

   University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Author : Daniel Griffin; [2023]
   Keywords : Space Elevator; Cislunar Space; Mass Transportation; Astronaut Safety; Apex Anchor; Rymdhiss; Cislunar-rymden; Masstransport; Astronautsäkerhet; Apex-ankaret;

   Abstract : To leave Earth’s gravity well and ascend into Cislunar space takes ingenuity, and the engineering feats of many. Now to propel humanity further into space, rockets will need assistance to provide the large requirements of mass to be used for space structures. READ MORE

4. 3. Gravity water waves over constant vorticity flows: from laminar flows to touching waves

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

   Author : Francisco Gonçalves Jorge Dias de Carvalho; [2023]
   Keywords : Partial differential equations; Water waves; Euler equations; Free boundary problem; Bifurcation theory; Nonlinear functional analysis; Hilbert transform; Mathematics and Statistics;

   Abstract : In a recent paper, Hur and Wheeler proved the existence of periodic steady water waves over an infinitely deep, two-dimensional and constant vorticity flow and subject to gravity whose profile overhangs, among which, waves whose surface touches at a point, enclosing a bubble of air. We take this further, proving the existence of a continuous curve of water waves from a laminar flow up to a touching wave for fixed non-zero gravity. READ MORE

5. 4. Theories with higher-order time derivatives and the Ostrogradsky ghost

   University essay from Stockholms universitet/Fysikum

   Author : Eleonora Svanberg; [2022]
   Keywords : Ostrogradsky ghost; higher-order time derivatives theories; Lagrangian mechanics; mathematical physics; Hamiltonian formalism;

   Abstract : Newton's second law, Schrödinger's equation and Maxwell's equations are all theories composed of at most second-time derivatives. Indeed, it is not often we need to take the time derivative of the acceleration. READ MORE

6. 5. Gravitation in Lorentz and Euclidean Geometry

   University essay from KTH/Fysik

   Author : Niki Wilhelmson; Johan Stoyanov; [2022]
   Keywords : gravitation; gravity; euclidean geometry; isometry; laplace; helmholtz; lorentz geometry; differential geometry; general relativity; special relativity; Einstein s field equations; Lovelock; Newton;

   Abstract : The aim of this work is to derive mathematical descriptions of gravitation. Postulating gravitation as a force field, Newton's law of gravitation is heuristically derived by considering linear differential operators invariant under euclidean isometries and by finding the fundamental solution to Helmholtz equation in three dimensions.
