  1. 1. Are They Part Of “Us” Or The “Other”? A Discourse analysis examining how the U.S. perceives itself in East Asia region in relation to the disputes between two important allies: Japan and South Korea

    University essay from Försvarshögskolan

    Author : Emma Mellstrand Sajnovic; [2024]
    Keywords : Foreign Policy; U.S.; Japan; South Korea; and Discourse analysis;

    Abstract : With the trilateral meeting between U.S. President Joe Biden, Japanese Prime Minister Kishida Fumio, and South Korean President Yoon Suk-Yeol in August 2023, a new chapter of cooperation between the three seems to be coming closer, with new possibilities of laying bilateral issues between Japan and South Korea to rest. But how does the U. READ MORE

  3. 2. Effect of temperature on early stage adhesion during TiAlN sliding against Inconel 718 and Stainless steel 316L : High temperature tribology

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Ahsan Ali; [2023]
    Keywords : High temperature tribology; Early-stage adhesion; Adhesive wear; Friction; Wear resistant coatings; Physical vapour deposition PVD coatings; TiAlN; Tungsten carbide WC Co ; Difficult to machine super alloys; Inconel 718; Stainless steel 316L; High-performance materials; Abrasion; Oxidation; Chipping; Ploughing; Characterization;

    Abstract : High-performance materials such as stainless steels and nickel based super alloys are widely used in demanding applications where high mechanical and thermal properties are required. The applications of super alloys are mainly found in jet engines, power plants and gas turbines demanding high fatigue strength, corrosion and oxidation resistance as well as wear resistant properties.

  4. 3. Additives in a steam engine to decrease friction : Friction testing of solid lubricants in powder form

    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

  5. 4. Comparison of properties on Orally Disintegrating Tablets (ODTs) produced by direct compression or fluid bed granulation

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Julia Ahlbom; [2023]
    Keywords : Orally disintegrating tablet; fluid bed granulation; disintegration time; pharmaceutical technology; Technology and Engineering;

    Abstract : Orally disintegrating tablets (ODTs) is a popular drug delivery system as they dissolve in the mouth, usually within seconds which enables easy medication for patients with problem swallowing. In this thesis properties of ODTs were compared when produced with direct compression of the excipients or the excipients were pretreated to form granules in a fluid bed granulator prior to tableting.

  6. 5. Tribological characterization of a ball bearing subjected to an electric field : Electric drivetrain tribology

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Muhammad Umar Farooq; [2023]
    Keywords : Ball bearing; electric drivetrain; tribology; electric field; characterization; bearing currents; discharge;

    Abstract : Electric machines are widely used in for instance the automotive industry in electric vehicles and in wind turbines. The electrical machines have mechanical bearings as an integral part used to transmit power and load. In addition, the main function includes reducing friction between interacting surfaces. READ MORE
