1. 1. Benchmarking a 1 kW hybrid hydrogen fuel cell system

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Jonathan Envall; [2023]
   Keywords : PEMFC; fuel cell; UAV; hybrid; Technology and Engineering;

   Abstract : Unmanned Aerial Vehicles (UAV's) offer great versatility in the tasks that they may perform and they are today used in many sectors. The H24LEO project, administered by the Lund University School of Aviation, aims to develop and demonstrate a hybrid proton-exchange membrane fuel cell-powered UAV to aid in search and rescue operations performed by the Swedish Maritime Administration, and reduce the greenhouse gas emissions compared to similar work performed by helicopters.

4. 3. Lignin modification for higher reactivity towards epoxides

   University essay from KTH/Fiber- och polymerteknologi

   Author : Filip Rynkiewicz; [2023]
   Keywords : Lignin; modification; reactivity; epoxide; oxidation; Lignin; modifikation; reaktivitet; epoxid; oxidation;

   Abstract : Fem metoder har använts för att modifiera barrvedslignin med syftet att öka reaktiviteten av ligninet mot epoxidgrupper. Ligninprover analyserades med NMR och FTIR medan reaktivitet var mätt genom reometri. Metoder som ökade mängden karboxylsyragrupper på ligninet minskade ligninets reaktivitet. READ MORE

5. 4. Unsupervised Machine Learning Based Anomaly Detection in Stockholm Road Traffic

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)
