  1. 11. Low-Frequency Noise in InGaAs Nanowire MOSFETs

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Christian Mario Möhle; [2017]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Low-frequency (LF) noise (1/f as well as random telegraph-signal (RTS) noise) measurements were performed on high-performance InGaAs nanowire (NW) metal-oxide-semiconductor field-effect transistors (MOSFETs). 1/f noise measurements at room temperature (RT) show that the dominant noise mechanism is carrier number fluctuations.

  3. 12. Determination and compensation of magnetic dipole moment inapplication for a scientific nanosatellite mission

    Master-uppsats, KTH/Rymd- och plasmafysik

    Författare :Csaba Jéger; [2017]
    Nyckelord :cubesat; magnetic dipole estimation; attitude dynamics; cubesat; magnetisk dipol uppskattning; attityddynamik;

    Sammanfattning : SEAM (Small Explorer for Advanced Missions) is a 3U CubeSat developedat KTH Royal Institute of Technology which will provide highqualityDC and AC magnetic field measurements of Earth’s magneticfield. The measurement system requires extended periods of timeup to 1000 seconds without active attitude control. LÄS MER

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Isak Lindmark; [2017]
    Nyckelord :Media central; Car stereo; Communication; Bluetooth; Malux Voyager; ANC; Active Noise Control; Multiplexer; Audio; Microphones; SNR; Signal to Noise Ratio; Mediacentral; bilstereo; kommunikation; Bluetooth; Malux Voyager; ANC; Aktiv bullerreducering; Multiplexer; Ljud; Mikrofoner; SNB; Signal-brusförhållande;

    Sammanfattning : Komatsu Forrest AB have a demand for a media solution where the user can select between different input sources as well as output channels. The input sources are Radio, Bluetooth, AUX, two microphones and PC. The system shall also be able to mix sound from an ANC unit (Active Noise Control). LÄS MER

  5. 14. Extending the capabilities of existing Remote Laboratory for Active Noise Control

    Master-uppsats,

    Författare :Piotr Konopka; Maciej Żmuda; [2017]
    Nyckelord :Active Noise Control; Remote Laboratories; Spatial Positioning; VISIR;

    Sammanfattning : The aim of the thesis is to upgrade an existing Remote Laboratory for Active Noise Control (ANC) and acoustics experiments providing users with a more authentic real life experience. This is done by designing a solution that allows remote position control of microphones inside a ventilation duct for ANC experiments. LÄS MER

  7. 15. Evaluation of Missile Guidance and Autopilot through a 6 DOF Simulation Model

    Master-uppsats, KTH/Optimeringslära och systemteori

    Författare :Ulf Sefastsson; [2016]
    Nyckelord :Missile Guidance; Proportional Navigation; Optimal Guidance; Differential Game Guidance; Model Predictive Control.; Missilstyrning; syftbäringsstyrning; optimal missilstyrning; spelteoretisk missilstyrning; modellprediktiv reglering;

    Sammanfattning : Missile guidance and autopilot have been active fields of research since the second world war. There are lots of literature on the subjects, but the bulk of which are confined to overly simplified models, and therefore the publications of the methods applied to more realistic models are scarce.
