1. 1. Hydraulic Modelling of Eurasian Beaver Structural Modifications: Implications for Evaluating their Contributions to Natural Flood Management in Scotland

   University essay from Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

   Author : Maja Christina Pitcairn; [2023]
   Keywords : Beaver reintroduction; Scotland; Flood risk; Natural flood management; Hydraulic modelling.; Technology and Engineering;

   Abstract : The concurrent climate and biodiversity crises in Scotland necessitate the exploration of ecosystem-based adaptation to simultaneously address increased flood risk and the loss of native species. This research investigated the contributions of Eurasian beaver reintroductions to natural flood management in Scotland. READ MORE

3. 2. Evaluation of a computational method for natural fiber-reinforced plastics

   University essay from KTH/Hållfasthetslära

   Author : Anna Lim; [2023]
   Keywords : PPNF; Composite material; fiber orientation; natural fiber; coupled analysis; PPNF; Kompositmaterial; fiberorientering; naturfiber; kopplad analys;

   Abstract : The importance of using natural fiber composites (NFCs) has been addressed as a substitution for synthetic fibers, such as glass and carbon fibers. This substitution contributes significantly to reducing greenhouse gas emissions, aligning with the environmental responsibilities of engineering industries. READ MORE

4. 3. Evaluation of Physics Informed Neural Networks in engineering simple structural analysis problems

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Georgios Nentidis; [2023]
   Keywords : ;

   Abstract : Neural Networks have found many applications for a long time in Machine Learning in different disciplines, and have especially flourished in the last decade because of the ever-increasing processing power especially from GPUs. Because of their ability to operate as universal function approximators and model nonlinear processes, attempts have been made in recent years to be also used for modeling partial differential equation (PDE) solutions.

5. 4. Investigation of Milled Wood Lignin Extraction Using Enzymatic Hydrolysis for Application in Hydrophobic Barriers in the Food Packaging Industry

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Anna Wagne; [2023]
   Keywords : Lignin; extraction; hydrophobicity; chemical engineering; Technology and Engineering;

   Abstract : The objective of this report is twofold: to optimise the extraction method of lignin from spruce altering a few process parameters and to investigate the use of lignin as a hydrophobic barrier in food applications. The process used was STEX (steam explosion) pretreatment followed by enzymatic hydrolysis and MWL (milled wood lignin) extraction using a mixture of dioxane-water. READ MORE

6. 5. Reprocessing and Characterization of Polybenzimidazole for High-Temperature Polymer Electrolyte Membrane Fuel Cells

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Douglas Björkengren; [2023]
   Keywords : polymer electrolyte membrane fuel cells; PEMFC; HTPEMFC; polymer technology; polymer characterization; reprocessing; recycling; polybenzimidazole; PBI; Technology and Engineering;

   Abstract : A reprocessing method of poly(2,2’-(m-phenylene)-5,5’-bibenzimidazole) (PBI) membranes recovered from the production line of High-Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) at Blue World Technologies (BWT) has been developed in order to reduce material loss in the production. Redissolution of scrap PBI membranes in poly(phosphoric acid) (PPA) and phosphoric acid (PA) was successful and the subsequent washing procedure produced PBI that could be redissolved in N,N-dimethyl acetamide (DMAc) and suitable for solution casting of new membranes.
