4. 3. A Scalability and Performance Evaluation of Precomputed Flow FieldMaps for Multi-Agent Pathfinding

   University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

   Author : Jonathan Helsing; Alexander Bruce; [2022]
   Keywords : pathfinding; flow field; multi-agent; precomputed; dijkstra maps;

   Abstract : Background. The A* algorithm is a well-established pathfinding technique frequently used in video game development. However, a disadvantage of the A* algorithm is that it becomes computationally inefficient and impractical to utilize whenthousands of agents demand an optimal path. READ MORE

5. 4. Optimizing Control Algorithm for Indirect Liquid ThermalManagement of Batteries : A Study Executed at Northvolt

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Mantas Petrosius; [2021]
   Keywords : ;

   Abstract : The vast expansion of intermittent sustainable energy generation has favoured a gradual adoption of lithium-ion batteries in various industrial and automotive applications. Despite its many inherent merits, this storage technology is very vulnerable to temperature variations: the performance and lifespan of LIBs are substantially influenced by their load cycles, thermal behaviours, and operating temperature range.
