  1. 1. Development of HVAC simulations for truck cabins using OpenFOAM

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Junaid Haider; [2023]
    Keywords : Computational Fluid Dynamics; OpenFOAM; Conjugate Heat Transfer; chtMultiRegionFoam;

    Abstract : In regions with cold climates, a layer of ice often forms on vehicle windshields, whichobstructs the driver’s view. To address this issue, vehicles are equipped with internal defrosters. However, at Scania, the evaluation of defroster design performancecurrently relies on time-consuming and costly physical testing. READ MORE

  2. 2. EVALUATION OF MULTI-ZONE MODELLING FOR FIRE RISK ASSESSMENT IN TUNNELS

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Annachiara Nardone; [2023]
    Keywords : tunnels; tunnel fires; multi-zone modelling; Technology and Engineering;

    Abstract : Abstract Tunnels are one of the most complex and delicate elements of the road system. Assessing fire behaviour and fire severity remains the biggest source of uncertainty in risk assessment and is an essential step in the tunnel design process. READ MORE

  3. 3. Evaluating Cold-Start in Recommendation Systems Using a Hybrid Model Based on Factorization Machines and SBERT Embeddings

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

    Author : Sabrina Chowdhury; [2022]
    Keywords : Natural Language Processing; Hybrid Recommender Systems; Cold-Start Problem; språkteknologi; hybrida rekommendationssystem; kallstartsproblemet;

    Abstract : The item cold-start problem, which describes the difficulty of recommendation systems in recommending new items to users, remains a great challenge for recommendation systems that rely on past user-item interaction data. A popular technique in the current research surrounding the cold-start problem is the use of hybrid models that combine two or more recommendation strategies that may contribute with their individual advantages.

  4. 4. Top Gas Blowing Technique to Prevent Slopping in Ladle and Basic Oxygen Steelmaking Process

    University essay from KTH/Materialvetenskap

    Author : Abdullah Harazeen; [2022]
    Keywords : slag; slag foaming; slopping prevention; BOS; LD converter; ladle furnace; foaming index; and cold model experiment;

    Abstract : In the steel industry, slag foaming plays a crucial role in many steel processes, given its positive impact on the thermal efficiency of the furnace and its life span. However, excessive foaming causes an overflow in the converter known as “slopping”. READ MORE

  5. 5. Development of heat recovery solution for heavy duty truck cabs to improve energy efficiency.

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Exekiel Aurelio; Rahul Acharya Rathnakar; [2022]
    Keywords : air-to-air heat recovery; air-to-liquid heat recovery; integrated thermal management system; heat wheel; heat pump; battery electric vehicle; battery electric trucks; energy savings.; luft-till-luft värmeåtervinning; luft-till-vätska värmeåtervinning; integrerat värmehanteringssystem; värmehjul; värmepump; batterielektriskt fordon; batterielektriska lastbilar; energibesparingar.;

    Abstract : The recent climate actions to reduce greenhouse gas (GHG) emissions have set the stage for decarbonizing the transportation sector through electrification, which has led to a surge in the deployment of battery electric vehicles (BEV). Trucks are no exception, which has led automakers to shift their focus toward producing Battery Electric Trucks (BET). READ MORE
