  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

  2. 2. Hybrid Beamforming Design for Full-Duplex mmWave Relaying Systems

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Zhe Wu; [2020]
    Keywords : mmWave; full-duplex; hybrid beamforming; self-interference cancellation; OMP; fast ADMM; convergence; mmwave; fullständig duplex; hybridstrålformning; självförstörande annullering; OMP; snabb ADMM; konvergens;

    Abstract : With the tremendous growth in the mobile data traffic, the demand for highdata rate is increasing rapidly, and higher frequency resources shall be exploredto alleviate the congestion in the overcrowded spectrum, thus, the millimeterwave (mmWave) frequency resource ranging from 30 GHz to 300 GHz has beenrecognized as a nature fit for the fifth-generation (5G) and beyond network. Tocompensate the severe path-loss in the mmWave band as well to realize theefficient transmissions by applying the low-cost architecture, it is of intereststo investigate the beamforming schemes with large-scale antenna arrays andthe full-duplex (FD) relaying strategy, which are indispensable in the operationof directional signal transmission and the efficient spectrum utilization inthe mmWave transmission, respectively.

  3. 3. Model selection and optimization experiment of a field trial with agricultural data using Python

    University essay from Lunds universitet/Matematik LTH

    Author : Lukas Bengtsson; [2018]
    Keywords : ADMM; Elastic Net; Model selection; optimization; Mathematics and Statistics;

    Abstract : Potato cultivation is vast for many agricultures in southern Sweden. What many might not be aware of, is how much pesticides which are used in the cultivation process. In "Late blight prediction and analysis"[1] predictions of late-blight attacks was modelled on potato-corps using Elastic Net among other methods. READ MORE

  4. 4. Distributed Control of Dynamic Flows in Traffic Networks

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Christian Rosdahl; [2017]
    Keywords : Technology and Engineering;

    Abstract : In today’s society, traffic congestion is a major problem in several aspects. Apart from the obvious problem that people are losing valuable time due to the resulting delays, it also has negative impact on as well the economy as the local and global environment. READ MORE
