  1. 1. Vibration reduction over junctions in buildings

    University essay from KTH/Marcus Wallenberg Laboratoriet MWL

    Author : Alexander Forsberg; Aras Wali; [2021]
    Keywords : Vibration reduction; Junction; Building acoustics; Vibrations minskning; Knutpunkt; Byggnadsakustik;

    Abstract : Structure borne sound can travel multiple paths from one office to another and choosing to sound insulate a specific building element can be difficult since all the building elements are connected together and form a coupled system. The current approach by engineers when investigating transmission paths between spaces in a building is using a computer model and assuming that the junctions are firmly clamped or free. READ MORE

  2. 2. The impact of noice pollution and vibrations on nearby buildings : How is the school Kulturama affected by noise and vibrations from the 'nya tunnelbana' project?

    University essay from KTH/Byggteknik och design

    Author : Hadil Jawad; Aren Nabatyan; [2021]
    Keywords : Noice pollution; vibrations; metro; nya tunnelbana project; noice absorbents; Buller; vibrationer; stomljud; luftburet ljud; nya tunnelbana projekt; absorbenter;

    Abstract : To meet the needs of the growing city of Stockholm, a large-scale project to expand the subway has been initiated. The tunneling involved in the project causes several disturbances, in terms of vibration and noise pollution, on the surroundings. This is problematic as vibration and noise pollution has been shown to have a negative health impact. READ MORE

  3. 3. Predicting comfort in autonomous driving from vibration measurements using machine learning models

    University essay from KTH/Fordonsdynamik

    Author : Kate Asarar; [2021]
    Keywords : Passenger comfort; Machine learning; Autonomous driving; Vibrationer; Passagerarkomfort; Maskininlärning; Vibrationer; Självkörande bilar;

    Abstract : Highly automated driving is approaching reality at a high speed. BMW is planningto put its first autonomous driving vehicle on the road already by 2021. The path torealising this new technology is however, full of challenges. READ MORE

  4. 4. Active stabilisation of a micro-sized fibre cavity using tilt locking to enable quantum operations on single ions

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Jannek Hansen; [2021]
    Keywords : Quantum computation; optical cavity; microcavity; locking; tilt locking; cavity stabilization; Gaussian-Hermitian modes; quantum computer; higher-order transverse modes; Physics and Astronomy;

    Abstract : In this thesis, the tilt locking scheme is applied to create an error signal that monitors length changes in a fibre-based microcavity. To find a robust and precise locking technique is an essential step towards quantum operations on single rare-earth ions doped in microcrystals. Quantum computing and information is a frontier of modern physics. READ MORE

  5. 5. Active Control of High­-Speed Flexible Rotors on Controllable Tilting­-Pad Journal Bearings : Theory and Experiment

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Paul-Henrik Bull; [2021]
    Keywords : ATPJB; Fluid-Film Lubrication; Model based control; Vibration Control;

    Abstract : A common choice of bearing for industrial applications such as turbomachinery and rotating compressors is the Tilting-Pad Journal Bearing (TPJB) due to its excellent stability properties. TPJB's are however limited by the reduction of damping in the fluid film at high velocities. READ MORE
