1. 6. Modeling of a ball contact with a coated plate

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

   Author : Mohammadreza Saeedi; [2023]
   Keywords : Pin on disc tribometer; coating; contact mechanics; finite element method; tribology; Pin on disc tribometer; beläggning; kontaktmekanik; finita elementmetod; tribologi;

   Abstract : During tightening of a screw, the variation in friction will affect the force acting on the joint, especially when tightening using torque as a control parameter. So, it is crucial to have a proper understanding of the contact mechanism and friction in the screw head to joint and thread interfaces. READ MORE

3. 7. New design and construction of hightemperature tribology testingequipment : in the context of hard coatings

   University essay from Karlstads universitet/Avdelningen för maskin- och materialteknik

   Author : Atle Andersson Nykvist; [2023]
   Keywords : Tribology; friction; wear; hot wear; hot wear tester; design; construction; tribometer; tribo tester; tribo-tester; Tribologi; friktion; nötning; varmnötning; varmnötare; design; konstruktion; tribometer; tribotest;

   Abstract : There are two main goals of this thesis. Firstly, to improve and develop an existing hot weartester at Karlstad University so that it may test more samples of different sizes. Secondly, totest previously impossible samples and investigate their tribological properties and measurethe coefficient of friction with high reproducibility. READ MORE

4. 8. TockTick : Adding Friction to TikTok Interaction

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

   Author : Ao Xu; [2022]
   Keywords : dark pattern; screen time control; reflective design; design friction; mörkt mönster; skärmtidskontroll; reflekterande design; designfriktion;

   Abstract : Many different strategies have been used to study screen time control to deal with the side effects of dark patterns. However, users might be annoyed by those methods that create too strong “friction” and give them up too soon. READ MORE

5. 9. Fibre volume fractions’ and printing directions’ effects on tribological and mechanical properties in FDM printed carbon fibre reinforced PEEK : Suitability assessment of FDM printed PEEK-CF to act in a steam engine’s ball joint, by analysis of compressive properties, impact strength, friction and wear

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

   Author : William Tönnberg; [2022]
   Keywords : Ranotor; steam engine; PEEK; polyether-ether-ketone; carbon fibre reinforced PEEK; impact strength; compressive strength; compressive modulus; friction; wear; tribology; FFF; FDM; 3D-printing; printing parameters;

   Abstract : The purpose with this study was to investigate FDM/FFF manufactured carbon fibre reinforced PEEK and assess its suitability to act as a sealing- and bearing material in a modern steam engine’s ball joint. The steam engine is totally free from oil due to the risk of water- and steam contamination. READ MORE

6. 10. Minimizing the expected opportunity loss by optimizing the ordering of shipping methods in e-Commerce using Machine Learning

   University essay from KTH/Matematik (Avd.)

   Author : Jonatan Ay; Jamil Azrak; [2022]
   Keywords : statistics; machine learning; applied mathematics; e-commerce; statistik; maskininlärning; tillämpad matematisk statistik; e-handel;

   Abstract : The shopping industry is rapidly changing as the technology is advancing. This is especially true for the online industry where consumers are nowadays able to to shop much of what the need over the internet. READ MORE
