  1. 1. Oscillations in a complex sunspot: From theory to data

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Femke Kranenbarg; [2024]
    Keywords : ;

    Abstract : Sunspot oscillations, intricate three-dimensional wave-like motions in the solar atmosphere, result from the complex interplay between plasma and magnetic fields. This study delves into the behaviour of these oscillations, exploring their simultaneous excitation and evaluating their impact on solar phenomena like coronal heating, energy transport, and solar flares.

  3. 2. Experimental optimization and analysis of drying in ifrasound dryer

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Shreeja-Sivaranjani Natarajan; [2022]
    Keywords : Infasound technology; Wheat drying and storage; Drying method; Simulation of drying; Infasound-teknik; Torkning och lagring av vete; Torkningsmetod; Simulering av torkning;

    Abstract : In the agricultural industries drying plays a major role as its very important for grain storage. The selection of the dryer and the method used for drying should be chosen wisely considering the product to be dried with its other factors. READ MORE

  4. 3. A simplified model for the design of floor structures with vibrating sources for architectural applications

    University essay from KTH/MWL Marcus Wallenberg Laboratoriet

    Author : Rebecca Janson; [2019]
    Keywords : ;

    Abstract : When designing a building, sound is one of the problems to take into account. Vibrating machines, such as ventilation fans, water pumps and compressors, generate structure-borne sound. The structure-borne sound travels up the structure of the building and generates sound in adjacent rooms. READ MORE

  5. 4. Ultrasonic measurement and analysis of screw elongation

    University essay from KTH/Hållfasthetslära (Avd.)

    Author : Anders Pärlstrand; [2018]
    Keywords : ;

    Abstract : Based on the customers' increasing demands on the precision of the preload in a screw joint Atlas Copco is investigating the opportunity to integrate ultrasonic technologies in their industrial tools in order to be able to measure the screw elongation and thereby preload. The preload in a screw joint is important when trying to optimize the joint in terms of weight and life time. READ MORE

  6. 5. An Investigation on PVDF Piezoelectric Elements and Linear Array Transducers

    University essay from Lunds universitet/Teknisk akustik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Ali Alkhudri; [2017]
    Keywords : Ultrasonic Transducer; Piezoelectric Element; PVDF; Frequency; Ultrasound Wave Penetration; PZT; Acoustic Impedance; raw data; linear array transducer; Technology and Engineering;

    Abstract : Ultrasonic waves are widely used in different application e.g. for sonar scanning in water and fetal imaging. Furthermore it is used for doing measurements on different materials to determine the thickness of the material or the velocity of sound inside it. READ MORE
