  1. 11. 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.

  5. 14. Code Synthesis for Heterogeneous Platforms

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

    Author : Zhouxiang Fu; [2023]
    Keywords : Code Synthesis; Heterogeneous Platform; Zero-Overhead Topology Infrastructure; Kodsyntes; Heterogen plattform; Zero-Overhead Topologi Infrastruktur;

    Abstract : Heterogeneous platforms, systems with both general-purpose processors and task-specific hardware, are largely used in industry to increase efficiency, but the heterogeneity also increases the difficulty of design and verification. We often need to wait for the completion of all the modules to know whether the functionality of the design is correct or not, which can cause costly and tedious design iteration cycles. READ MORE

  6. 15. Characterizing Bitcoin Use For Illicit Activities
