  1. 1. Characterisation of Non-metallic Inclusions in Special Steels using Electrolytic Extraction

    University essay from KTH/Materialvetenskap

    Author : Josefin Mvele Svensson; [2024]
    Keywords : Non-metallic inclusions; electrolytic extraction; SEM; Icke-metalliska inneslutningar; elektrolytisk extraktion; SEM;

    Abstract : When producing high strength special steels strict requirements are in place to assure the quality of the final product, both in terms of harmful elements and  the  content  of  non-metallic  inclusions  (NMI).  Achieving  cleanliness  is a  gradual  process  where all  the  steps  of  the  production  process  are  inter- connected, meaning that it is crucial to know the influence of each step in order to assure the contents of the final product.

  4. 3. High-Temperature Thermal Energy Storage for Innovative Hybrid CSP/PV Plants : A Comprehensive Design Optimization

    University essay from KTH/Energiteknik

    Author : Lorenzo Centonze; [2023]
    Keywords : ;

    Abstract : By means of a literature review, critical parameters in the context of thermal energy storage systems, particularly packed bed thermal energy storage systems are identified. The goals of this thesis project are to come up with an optimized design for a PBSTES and to evaluate the thermal performance of alternative storage materials derived from byproducts of industrial processes and natural rocks in order to reduce the environmental impact of the designed system.

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Viktor Lange; [2023]
    Keywords : Tribology; friction; wear; steam; steam engine; ranotor; invencon; invencon AB; steel; contact mechanics; hexagonal boron nitride; molybdenum disulfide; tungsten disulfide; lubricants; solid lubricants; Tribologi; friktion; nötning; ånga; ångmotor; stål; kontaktmekanik; smörjning; smörjmedel; fasta smörjmedel;

    Abstract : This thesis aims to investigate the coefficient of friction between steel on steel contacts with the addition of solid lubricants such as h-BN, WS2, MoS2 in powder form, in dry conditions and wet conditions. More specifically, the purpose is to enhance the sliding between the piston rings and cylinder block in a modern high temperature steam engine developed by RANOTOR. READ MORE

  6. 5. Life is like a Boxx : How do film production sites affect wireless transmission?

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

    Keywords : Boxx Atom; wireless transmission; radio shadows; video quality; link budget; signal attenuation; Boxx Atom; trådlös överföring; radioskugga; video kvalitet; länkbudget; signaldämpningg;

    Abstract : Wireless transmission is an everyday part of movie production and a tool many people use in their work. Work, on a movie production, is fast, intense, and varies in geographical location almost on a daily basis (sometimes several locations in a day). Despite this, the stream, the transmission, must hold so the crew can work. READ MORE
