  1. 16. Predicting eigenvalues and eigenmodes in non-rectangular rooms with machine learning techniques

    University essay from KTH/Teknisk akustik

    Author : Oscar Lundin; [2022]
    Keywords : Machine learning; Finite elements; Plane wave decomposition; ResNet; Room acoustics; Tensorflow; Keras; Eigenfrequency prediction; Maskininlärning; Finita elementmetoden; Planvåguppdelning decomposition; Rumsakustik; ResNet; Tensorflow; Keras; Prediktering av egenvärden; Egenfrekvenser; Egenmoder.;

    Abstract : Knowing the eigenfrequencies and eigenmodes is of great importance to interior design and a common acoustic engineering problem. Challenges in noise control makes knowing the lower eigenfrequencies particularly important. READ MORE

  3. 17. Heat transfer analysis on LED-board in closed environment

    University essay from Malmö universitet/Fakulteten för teknik och samhälle (TS)

    Author : Victor Eneberg; Johannes Linby; [2022]
    Keywords : LED; heat sink; motorcycle; light; headlight; FEM; CFD; IR camera; thermocouple; kylfläns; motorcykel; belysning; halvljus; IR-kamera; thermoelement;

    Abstract : Motorcyclists are more often involved in accidents with severe harm or even fatal outcome compared to other road users. An experienced motorcycle driver is well familiar with the problem when the day light is reduced. The visibility is of course highly decreased. READ MORE

  4. 18. Development of an Investigation Method to Analyse Effect of Laser Cutting on Iron Losses in an Electric Machine

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

    Author : Rishabh Raj; [2022]
    Keywords : Electrical machine; iron losses; laser cutting; loss models; manufacturing defects; single sheet tester; Elektrisk maskin; järnförluster; laserskärning; förlustmodeller; tillverkningsfel; enplåtsprovare;

    Abstract : In this fast pace world, climate change is one of the primary concerns worldwide. The world is racing towards reducing CO2 emissions by focusing on decreasing energy consumption. Electric motors capture about two-third of the industrial energy consumption, of which the most growing sector is electrical vehicles. READ MORE

  5. 19. Development of a subject specific 3D knee finite element model to estimate the effect of weight loss on cartilage biomechanics

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Julius Dahlgren; [2022]
    Keywords : biomechanics; knee; cartilage; subject-specific; finite element; FE; FEM; weight loss; osteoarthritis; Technology and Engineering;

    Abstract : Osteoarthritis (OA) is a common musculoskeletal disorder that degrades articular cartilage and is a leading cause of disability worldwide. Overweight has been considered a major risk factor of knee OA, and it is known that weight loss may reduce the risk of knee OA. READ MORE

  6. 20. Multibody modelling of the vibrations in an aircraft engine

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Charly Mollet; [2022]
    Keywords : Vibrations; Multibody Modelling; Rolling Bearings; Rotor Dynamics; Reduction Processes; Vibrationer; multikroppsmodellering; rullingslager; rotordynamik; reducktionsprocesser;

    Abstract : During the assembly of aircraft engines, some clearance is left in the rolling bearings mainly to reduce friction. However this clearance might allow the rolling element to vibrate during flight. Indeed, unwanted vibrations called non-synchronous vibrations (NSV) appear on the data recorded by the sensors on some development engines. READ MORE
