  1. 21. Partnership for sustainability : A qualitative study of the importancefor enhanced sustainability in thepartnership between mining suppliersand customers

    University essay from Umeå universitet/Företagsekonomi

    Author : Johan Persson; Karl Wallin; [2022]
    Keywords : Sustainability mining partnership;

    Abstract : Global warming is a severe threat to the climate and the planet's environment. Climate changehas been a growing area to focus on for the entire world, including all industries andbusinesses to date. READ MORE

  3. 22. Centennial Climate Variability

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Thomas Askjær; [2022]
    Keywords : Climate variability; paleoclimate; climatemodelsimulations; proxyrecords; spectralanalysis; model proxycomparison;

    Abstract : Throughout earths history, the climate have always naturally varied due to both external forcings and internal mechanisms. With the outlook on future climate change, it is important to understand the climate system and this includes its natural variability. Depending on the driving mechanisms, the variability happens over different timescales. READ MORE

  4. 23. Refinement and Investigation of Instruments for Emission Screening of Passenger Cars

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Marcus Ruderer; Signe Stéen; [2022]
    Keywords : Emission Screening; Real Driving Emissions; Light-Duty Vehicles; PEMS; SEMS; Emissionskontroll; RDE; Lätta Fordon; PEMS; SEMS;

    Abstract : A Portable Emissions Measurement System (PEMS) is widely used for analysing the emissions of a vehicle. However, the PEMS is quite cumbersome and time-consuming to use for vehicle testing. This thesis investigates the possibilities of a Smart Emissions Measurement System (SEMS) and how it correlates to the more advanced PEMS. READ MORE

    Abstract : Is it possible to increase traffic flows and decrease stand stills in rush hour traffic by tweaking existing traffic light signals? A vehicle’s engine running on idle is not useful in physical terms and emits unnecessary exhausts. By investigating and observing signal phase times on site in Hangzhou, China, an effort was made to find out if it was possible to get better flow and thus lower emissions by changing the traffic signal programs.

  6. 25. Optimal Control and Thermal Managementof Heavy-Duty FCHEV Powertrains : Minimizing hydrogen consumption of an FCHEV using numerical optimal control and an integrated energy and thermal management system

    University essay from Linköpings universitet/Fordonssystem

    Author : Daniel Similä; Jonatan Siönäs; [2022]
    Keywords : Control Engineering; Powertrain Engineering; FCHEV; Optimal Control; Thermal Management;

    Abstract : The CO2 emissions from road vehicles must be reduced in order to avoid a 1.5 ◦C global warming. To reduce tailpipe emissions, a strong trend is to electrify powertrains to shift away from the use of fossil fuel. Among alternatives, the fuel cellhybrid electric vehicle (FCHEV) is seen as a promising configuration. READ MORE
