1. 1. Customizable Contraction Hierarchies for Mixed Fleet Vehicle Routing : Fast weight customization when not adhering to triangle inequality

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

   Author : Martin Larsson; [2023]
   Keywords : Contraction Hierarchies; Customizable Contraction Hierarchies; Vehicle Routing Problem; Battery Electric Vehicles; Mixed Fleet; Kontraktionshierarkier; Anpassningsbara Kontraktionshierarkier; Ruttplanering; Batteridrivna elfordon; Blandad fordonsflotta;

   Abstract : As the transport industry shifts towards Battery Electric Vehicles (BEVs) the need for accurate route planning rises. BEVs have reduced range compared to traditional fuel based vehicles, and the range can vary greatly depending on ambient conditions and vehicle load. READ MORE

3. 2. Route Planning of Battery Electric Heavy-Duty Commercial Vehicles : Using Contraction Hierarchies and Mixed Integer Programming

   University essay from Uppsala universitet/Datalogi

   Author : Olle Delborg; Elias Insulander; [2023]
   Keywords : route planning; route optimization; contraction hierarchies; mixed integer programming; vehicle routing problem; electric trucks; electric vehicles; battery; openstreetmap; shortest path; Dijkstra;

   Abstract : This thesis addresses route planning of Battery Electric Heavy-Duty Commercial Vehicles to enhance the reliability of electric vehicle transport. Collaborating with Scania, a Swedish truck manufacturing company, the goal is to develop a pipeline that uses open source data from OpenStreetMap and performs a modified Contraction Hierarchy in order to create a graph that can be used as input to a modified Vehicle Routing Problem formulation using Mixed Integer Programming.

4. 3. 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.

5. 4. Evaluating Thread network performance, locating and strengthening weak radio links

   University essay from Linköpings universitet/Fysik, elektroteknik och matematik; Linköpings universitet/Tekniska fakulteten

   Author : André du Rietz; Elias Salo; [2023]
   Keywords : Internet of Things; IoT; Thread network; Evaluating Thread Network;

   Abstract : In the fast-developing world we are living in, a tech phenomenon known as the Internet of Things (IoT) has taken hold. It has seen a lot of development over the past few decades, and today there are an estimated 30 billion IoT devices active. IoT is a machine-to-machine network that senses the world with the help of sensors. READ MORE

6. 5. A Method for Optimizing for Charging Cost in Electric Vehicle Routing

   University essay from Malmö universitet/Institutionen för datavetenskap och medieteknik (DVMT)

   Author : Matthew Lehrer; [2023]
   Keywords : Electric Vehicle Routing; Electric Vehicles; Shortest Path Problem with Constraints; EV; Charging Stations; Cost Optimization;

   Abstract : Adoption of electric vehicles has been restrained by the availability of charging stations and consumer fear of being stranded with a depleted battery, far from the nearest charger. In many areas of the world, charging stations are now widely available and the transition from vehicles with internal combustion engines is accelerating, though still in a fairly early stage.
