1. 1. 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

3. 2. Influence of supercritical carbon dioxide (scco2) dyeing parameters on color fastness of polyester fabric dyed with disperse dye : A study towards minimizing the energy consumption of polyester (pet) fabric dyeing with azo disperse dye

   University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Author : Tapas Das; [2023]
   Keywords : Supercritical fluid dyeing; polyester PET fabric; coranger orange PE3330; color fastness; ideal dyeing conditions; eco-friendly;

   Abstract : Amid growing environmental concern and continuous depletion of natural resources (such as water), the textile industry is constantly searching for sustainable production process. Traditional dyeing processes, notorious for their enormous water consumption, have led society to search alternative dyeing method. READ MORE

4. 3. Fashionable & Sustainable? A case study exploring the markets contribution to the ethical consumption gap

   University essay from Lunds universitet/Företagsekonomiska institutionen

   Author : Emma Tyledal; Emelie Blennow; [2022]
   Keywords : Ethical consumerism; ethical consumption gap; consumer sovereignty; consumer responsibilization; fashion; market; Social Sciences;

   Abstract : The primary purpose of this study is to examine how the market contributes in creating the ethical consumption gap to serve the underlying structures in which predicates and benefits from the gap. Consequently, the research seeks to add to current theoretical understanding in the field. READ MORE

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

   Author : Eneas Hållsten; [2022]
   Keywords : Technology and Engineering;

   Abstract : Wireless power transfer is emerging into everyday life. The idea is to create a more convenient way of charging, or at least powering, devices. READ MORE

6. 5. Study of process parameters in laser beam welding of copper hairpins

   University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

   Author : Dan Lönn; David Spångberg; [2022]
   Keywords : Laser Welding; Hairpin Welding; Copper Laser Welding; Process Parameter; Multi-Physical Simulation; Computed Tomography Scan; Design of Experiment;

   Abstract : This study had the purpose to further the use of industrial lasers in the manufacturing of hairpin electric motors by optimizing the process of contacting the hairpins. A problem with laser beam welding of copper is the porosity created in the process which can lead to increased resistance of the welded region along with degraded mechanical properties. READ MORE
