  1. 1. Exploiting the Overtones in Online Localization of Sound Sources

    University essay from Lunds universitet/Matematisk statistik

    Author : David Sundström; [2022]
    Keywords : Multi-pitch estimation; localization; block sparsity; sparse recursive least squares; online estimation; ADMM; adaptive dictionary; Mathematics and Statistics;

    Abstract : Localization of multiple sound sources from a microphone array is a challenging task that has been a research topic for decades. The challenges stem from the diversity of acoustic contexts due to reverberation and disturbances. READ MORE

  3. 2. A Close Look at the Transient Sky in a Neighbouring Galaxy

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Kiran Tikare; [2020]
    Keywords : Astrophysical Transients; Optical Transients; Microlensing; Variable Stars; Andromeda Galaxy; Forced Aperture Photometry; Time Domain Astronomy; Sky Survey; Zwicky Transient Facility; Machine Learning; Big Data Science;

    Abstract : Study of the time variable sources and phenomena in Astrophysics provides us with important insights into the stellar evolution, galactic evolution, stellar population studies and cosmological studies such as number density of dark massive objects. Study of these sources and phenomena forms the basis of Time Domain surveys, where the telescopes while scanning the sky regularly for a period of time provides us with positional and temporal data of various Astrophysical sources and phenomena happening in the Universe.

    Keywords : Chao Phraya River Basin; flood risk assessment; 2D hydrodynamic model; fully 2D and coupled 1D 2D numerical methods; KULTURisk methodology; depth-damage functions;

    Abstract : Thailand has been often affected by severe flood events over the past century. The 2011’s Thailand Flood Catastrophe was the costliest in country’s history, and it was ranked to be the second most damaging natural hazard in the world in terms of economic losses. READ MORE

  5. 4. In the eye of the storm : a gendered study on climate change adaptation in small-scale farming in Thái Bình, Vietnam

    University essay from Lunds universitet/LUCSUS

    Author : Josephine Ylipää; [2018]
    Keywords : gender; climate change adaptation; livelihoods; policy; sustainability science; Vietnam; Social Sciences;

    Abstract : Vietnam is one of the countries in the world that is projected to be most impacted by climate change. Extreme weather events such as storms and floods are predicted to increase with the changing climate. As such, climate change adaptation is crucial, especially for farmers who are relying on vulnerable livelihoods to climate change. READ MORE

  6. 5. A self-calibrating system for finger tracking using sound waves

    University essay from Lunds universitet/Matematik LTH

    Author : Linus Hammarlund; [2017]
    Keywords : cfrc; gcc-phat; srp-phat; self-calibration; toda; toa; Technology and Engineering; Mathematics and Statistics;

    Abstract : In this thesis a system for tracking the fingers of a user using sound waves is developed. The proposed solution is to attach a small speaker to each finger and then have a number of microphones placed ad hoc around a computer monitor listening to the speakers. READ MORE
