  1. 1. Processing of task-irrelevant sounds while performing a visual task : A study of auditory steady-state evoked potentials

    Kandidat-uppsats, Stockholms universitet/Psykologiska institutionen

    Författare :Jenny Arctaedius; [2020]
    Nyckelord :Attention; Auditory Processing; Perceptual load; ASSRs; Filtering; EEG;

    Sammanfattning : Perceptual capacity and selection in attention have for long been an interest in cognitive science, with early theories of early selection to late selection. Hearing is an important subject to investigate when it comes to attention and early auditory processing can be investigated by using auditory steady state responses (ASSRs). LÄS MER

  2. 2. Method for coupling modulatedscattered light from free flyinginsects to harmonics and theirrelative phases

    Master-uppsats, Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk statistik

    Författare :Martin Patricks; Ludvig Anderberg; [2020]
    Nyckelord :frequency estimation; phase estimation; matched phase reassignment; entomologic lidar; modulation spectroscopy; scattered light; Technology and Engineering;

    Sammanfattning : Using laser it is possible to measure the backscattered light from insects. The resulting signal can then be analysed in order to potentially determine the species of the insect. LÄS MER

  3. 3. Industrial Scenario using LTE Cellular Network

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Anthony Owondo; Javad Blouchi; [2019]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This Thesis project used an event-based simulation tool written in MATLAB that modelled a factory scenario. Multiple base stations and a varying number of nodes were modelled. The nodes send data to the base stations and the simulation tool calculates the SINR of the received data and uses this SINR to model a probability of error. LÄS MER

  4. 4. CURRENT OVERSAMPLING ANALYSIS FOR ADVANCED CONTROL OF ELECTRIC AC DRIVES

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Marco Giuliato; [2019]
    Nyckelord :;

    Sammanfattning : The main purpose of this thesis is to develop a sensorless control for a synchronous reluctance motor by using the slope measurement of the current ripple introduced by the Space Vector Modulation.The position estimation is performed at each Space Vector Pulse Width Modulation period and it relies on the estimation of current derivatives.

  5. 5. FPGA Co-Processing in Software-Defined Radios

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Leon Fernandez; [2019]
    Nyckelord :Internet of Things; Software-Defined Radio; USRP; GNU Radio; IEEE 802.15.4; Sakernas Internet; Mjukvarudefinierad Radio; USRP; GNU Radio; IEEE 802.15.4;

    Sammanfattning : The Internet of Things holds great promises for the future. In the smart cities of tomorrow, wireless connectivity of everyday objects is deemed essential in ensuring efficient and sustainable use of vital, yet limited resources such as water, electricity and food. However, radio communication at the required scale does not come easily. LÄS MER
