1. Customizable Contraction Hierarchies for Mixed Fleet Vehicle Routing : Fast weight customization when not adhering to triangle inequality
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : 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. LÄS MER
2. Route Planning of Battery Electric Heavy-Duty Commercial Vehicles : Using Contraction Hierarchies and Mixed Integer Programming
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/DatalogiSammanfattning : 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.

3. Design of transport solution for truck plant line simulator
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : Volvo Trucks is the second-largest heavy-duty truck provider in the world. As of now they are working towards fossil free transport solutions. LÄS MER
4. Particulate matter analysis from engine outlet in heavy-duty diesel vehicles : A study of soot reactivity, morphology and ash-to-soot ratio from the outlet of 6-cylinder and 8-cylinder diesel engines.
Master-uppsats, KTH/KemiteknikSammanfattning : De ökande luftföroreningarna i Europa är ett allvarligt miljöproblem, och vägtransporterna är en av de största orsakerna till detta. För att ta itu med detta problem och uppfylla nya utsläppskrav måste efterbehandlingssystemen för avgaser förbättras. LÄS MER
5. Development of an Accelerated Test Method for Compressed Natural Gas Fuel System Robustness against Contamination
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : A key factor for driving the shift towards sustainable transportation systems is alternative fuels, where compressed natural gas (CNG) is a beneficial alternative to the conventional fossil fuels with respect to greenhouse gas emissions. A fuel system is needed for heavy-duty natural gas vehicles, in order to transport the highly pressurized gas from the fuel tanks to the internal combustion engine. LÄS MER
