  1. 1. Perceptually meaningful time and frequency resolution in applying dialogue enhancement in noisy environments : Dialogue Enhancement research

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

    Författare :SUSHANTH PATIL; [2023]
    Nyckelord :Dialogue enhancement; audio signal processing; Fourier transform; time constants; environmental noise analysis; noise compensation; subjective listening test; speech intelligibility; quality of experience; listening effort.; Dialogförbättring; ljudsignalbehandling; Fouriertransform; tid konstanter; miljöbrusanalys; bruskompensation; subjektivt lyssnande test; taluppfattbarhet; upplevelsekvalitet; lyssnaransträngning;

    Sammanfattning : Dialogue Enhancement (DE) is a process used in audio delivery systems to improve the clarity, intelligibility, and overall quality of the spoken dialogue in audio content. It is primarily used when dialogue is masked by music, surrounding noise, or other audio sources. LÄS MER

  3. 2. Activity quantification of 177Lu using a 360◦ CZT gamma camera - comparison with a dual-head Anger camera

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Albin Lindvall; [2023]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Background and Aim: New SPECT cameras that use CZT detectors in a 360◦ configuration has recently been introduced. Together with Bayesian reconstruction methods employing Median Root Prior (MRP) and Relative Difference Prior (RDP), this constitutes an alternative to Anger-based SPECT for activity quantification.

  4. 3. Bedömning av enskilda trafikimmissioners marknadsvärdepåverkan på småhus vid anläggning, omläggning och breddning av väg.

    Master-uppsats, Lunds universitet/Fastighetsvetenskap

    Författare :Elenie Beyene; [2023]
    Nyckelord :Environmental damage; market reduction; property value; property valuation; assessment. Miljöskada; företagsskada; marknadsvärdeminskning; fastighetsvärdering; bedömning.; Technology and Engineering; Law and Political Science;

    Sammanfattning : During the construction, realignment, or widening of roads, various disturbances can occur that affect the market value of nearby properties. These disturbances typically include things such as increased noise, vibration, changes in soil conditions, increased sensitivity to wind, and all contibute to severe disruption of the property.

  5. 4. Heterogeneous catalytic reactions studied with transient gas supply and event-averaged ambient pressure x-ray photoelectron spectroscopy

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/NanoLund: Centre for Nanoscience

    Författare :Qianhui Liu; [2022]
    Nyckelord :Ambient pressure x-ray photoelectron spectroscopy; Event-averaging; Pd 100 surface structure oscillation; Physics and Astronomy;

    Sammanfattning : CO oxidation over Pd(100) is studied with ambient pressure x-ray photoelectron spectroscopy (APXPS). Cyclic gas composition pulsing of the CO:O2 ratio, combined with a new method using software based event-averaging by image recognition over many pulses, is used to improve the signal-to-noise ratio substantially.

  7. 5. Extraction of Loudspeaker- and room impulse responses under overlapping conditions

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Felix Gustafsson; [2022]
    Nyckelord :Signal processing; Optimization; Acoustics; Dereverberation; Sparse deconvolution; Multipath propagation;

    Sammanfattning : A loudspeaker is often considered to be a Linear Time Invariant (LTI) system, which can be completely categorized by its impulse response. What sets loudspeakers apart from other LTI-systems is the acoustical aspect including echoes, which makes it a lot harder to take accurate noise free measurements compared to other LTI-systems such as a simple RC circuit.
