1. 1. Design Investigation of Passive Radiators in Loudspeakers

   University essay from Lunds universitet/Innovation

   Author : Fabrice Dufberg; Valter Hamberger; [2024]
   Keywords : passive radiator; loudspeaker; speaker tuning; Thiele Small parameters; frequency response; Technology and Engineering;

   Abstract : Passive radiators are components that can be integrated into loudspeakers to amplify the bass frequencies. To ensure good sound quality, the passive radiator, the speaker driver, and the loudspeaker enclosure must all be well-dimensioned and fine-tuned in relation to each other. READ MORE

3. 2. Design and investigation of a pulsating heat pipe for electronic cooling

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Sulafa Hammad; [2023]
   Keywords : Pulsating heat pipes PHP ; Electronic cooling; two phase flow heat transfer; Technology and Engineering;

   Abstract : The purpose of this study is to design and investigate a pulsating heat pipe device (PHP). A PHP is a two-phase flow heat transfer device which can handle high heat fluxes with passive internal flow. It is made of a continuous loop serpentine, partially filled with a working fluid that can cool systems, such as electronic devices. READ MORE

4. 3. Load Control Aerodynamics in Offshore Wind Turbines

   University essay from KTH/Kraft- och värmeteknologi

   Abstract : Due to the increase of rotor size in horizontal axis wind turbine (HAWT) during the past 25 years in order to achieve higher power output, all wind turbine components and blades in particular, have to withstand higher structural loads. This upscalingproblem could be solved by applying technologies capable of reducing aerodynamic loads the rotor has to withstand, either with passive or active control solutions. READ MORE

5. 4. Active and semi-active suspensions for articulated vehicles to minimise tyre wear

   University essay from KTH/Väg- och spårfordon samt konceptuell fordonsdesign

   Author : Haoran Zhang; [2021]
   Keywords : Articulated vehicle; tyre wear; quarter car model; semi-active and active suspension; Ledat fordon; däckslitage; kvartsbilsmodell; semiaktiv och aktiv fjädring;

   Abstract : Tyre wear is a vital problem in vehicles, especially in articulated vehicles because of their heavier axle loads. Tyre wear can not only do harm to vehicle dynamics but also cause tyre particle emissions. Therefore, solutions that can minimise tyre wear are where this thesis work focuses. READ MORE

6. 5. Microeletromechanical Systems for Tunable Ring Resonators on a Silicon Platform

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

   Author : Chris Phong Van Nguyen; [2021]
   Keywords : Integrated photonics; Silicon Photonics; MEMS; Silicon Photonic MEMS; Ring Resonator; Telecommunications; Integrerad fotonik; Silicon Photonics; MEMS; Silicon Photonic MEMS; Ringresonator; Telekommunikation;

   Abstract : Advancements in photonic integrated circuits, so-called PICs, have progressed fast in the last decades. More complex PICs are getting developed, which are promising in possibly offering advantages like low power consumption and high-performance computing. Re-programmable photonic FPGAs are one of these candidates. READ MORE
