Objective: Find out how airlines can reduce their emissions and become more sustainable. READ MORE

  3. 2. Voltage-Based Multi-step Prediction : Data Labeling, Software Evaluation, and Contrasting DRL with Traditional Prediction Methods

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Joakim Svensson; [2023]
    Keywords : Deep Reinforcement Learning; Multi-step Prediction; Time Series Forecasting; Djup Förstärkningsinlärning; Flerstegsprognos; Tidsserieprognos;

    Abstract : In this project, three primary problems were addressed to improve battery data management and software performance evaluation. All solutions used voltage values in time together with various device characteristics. Battery replacement labeling was performed using Hidden Markov Models. READ MORE

  4. 3. Servicing or Buying New? Estimating the Environmentally Optimal Time for Car Replacement in Sweden – an LCA Approach.

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Larissa Patricia Wissert; [2022]
    Keywords : Sustainable Development; Life Cycle Analysis LCA ; Vehicle Replacement; ICEV; BEV; GHG Emissions;

    Abstract : Purpose. Road transportation is one of the major sources of GHG emissions today. Technological improvements in fuel consumption, as well as the electrification of vehicles can reduce emissions from road transportation. This study aims to investigate the optimal time for vehicle replacement in Sweden for an ICEV to minimise GHG emissions. READ MORE

  5. 4. RC Trough Bridges: A Parametric Study using FEM and an Analysis of their Current State

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : David Åkergren; [2021]
    Keywords : concrete; trough bridges; parametric study; FEM; BaTMan; ATENA; load eccentricity; compressive strength; tensile strength;

    Abstract : There are approximately 4000 railway bridges in Sweden managed by the Swedish Administration of Transport (Trafikverket), of which a common construction type is the reinforced concrete (RC) trough bridge, which is a structure that consists of a slab carried by two longitudinal main beams which transfer loads towards the supports. A substantial amount of the RC trough bridge population is approaching the end of their service lives which consequently implies that the replacement of some of these bridges can be expected in the near future.
