  1. 36. Extension of low voltage distribution by pure DC or mixed AC/DC parts for integration of solar PV and EV charging

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

    Author : Sofie Jiang; [2022]
    Keywords : LVDC; LVAC; solar PV system; electric vehicle charging station; IKN-regulation; distribution system; RES integration; LVDC; LVAC; solceller; elfordon; laddstolpar; IKN-regelverk; distributionsnät; förnyelsebara energikällor;

    Abstract : This work examines the local distribution system in two residential areas in two Swedish towns, Oxelösund and Karlskrona, and studies how integration of PV systems and electric vehicle (EV) charging stations (CS) will affect the present distribution system. The research questions focus on the economic feasibility of a LVDC system, how it compares to a traditional LVAC (low voltage alternating current) system from an economic and technical perspective, and the possibilities a LVDC system brings to other DC component applications.

  3. 37. “Det var en prestation i dagens nu. Det får man tycka!” : en jämförande studie av skogsarbetarkockornas arbete i två olika delar av Norrland

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Olivia Forssén; Emma Stridsman; [2022]
    Keywords : skogshistoria; kocka; kvinnor i skogsbruk; Norrland; Norrbotten; Tornedalen; Västernorrland; Jämtland;

    Abstract : During the 1930’s, it was common for female forestry cooks to start cook and clean in the remote logging cabins. The forestry cooks improved the standard for the forest workers when they cooked healthy food and cleaned. READ MORE

  4. 38. Developing a supervised machine learning model for an optimised aluminium addition based on historical data analytics, for clean steelmaking

    University essay from KTH/Materialvetenskap

    Author : Arun Kumar Thakur; [2022]
    Keywords : Clean steelmaking; Data analytics; De-oxidation; Machine learning; Ren ståltillverkning; Dataanalys; Deoxidation; Maskininlärning;

    Abstract : De-oxidation is an important process in clean steelmaking. Al (Aluminium) is mainly used as de-oxidant and controls the final oxygen content and impact the sulphur removal in steel. Adding optimum amount of Al is critical for steel cleanliness and to reduce cost. READ MORE

  5. 39. Characterization of commercially pure titanium under supercritical conditions : By means of hybrid numerical-experimental approach

    University essay from KTH/Materialvetenskap

    Author : Ricardo Rodríguez; [2022]
    Keywords : ;

    Abstract : Material characterization was addressed by solving the inverse engineering problem to mechanical properties by means of finite element analysis and computational optimization. High-temperature and high strain-rate data from split Hopkinson pressure bar tests on commercially pure titanium were used in the study. READ MORE

  6. 40. SSRT of 10-4 FeCrAl in LBE and Pb to Characterize Liquid Metal Embrittlement Effects

    University essay from KTH/Fysik

    Author : Daniel Stein; [2022]
    Keywords : Liquid Metal Embrittlement; Lead; Bismuth; Lead-Bismuth Eutectic; Slow Strain Rate Testing;

    Abstract : In this work the susceptibility of Fe-10Cr-4Al steel to liquid metal embitterment (LME)in low oxygen environment was investigated. slow strain rate testing (SSRT) wereconducted on 10-4 FeCrAl steel in a stagnant lead from 340-480◦C, lead-bismutheutectic (LBE) from 140-450◦C and lead-bismuth mixture at 375◦C with increasingbismuth content from 0.
