  1. 1. Robust Non-Linear State Estimation for Underwater Acoustic Localization : Expanding on Gaussian Mixture Methods

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

    Author : Diogo Antunes; [2023]
    Keywords : Robust state estimation; Underwater localization; Target tracking; Gaussian mixture; AUV; Estimação robusta de estado; Localização subaquática; Rastreamento de alvos; Mistura Gaussiana; AUV; Robust tillståndsuppskattning; Undervattenslokalisering; Målspårning; Gaussisk blandning; AUV;

    Abstract : Robust state estimation solutions must deal with faulty measurements, called outliers, and unknown data associations, which lead to multiple feasible hypotheses. Take, for instance, the scenario of tracking two indistinguishable targets based on position measurements, where each measurement could refer to either of the targets or even be a faulty reading.

  3. 2. Blind Acoustic Feedback Cancellation for an AUV

    University essay from Linköpings universitet/Reglerteknik

    Author : Hampus Frick; [2023]
    Keywords : acoustical feedback; adaptive filter; least leaky mean square; Kalman; blind source separation; independent component analysis; complex independent component analysis; degenerative unmixing estimation technique; convolutive mixture;

    Abstract : SAAB has developed an autonomous underwater vehicle that can mimic a conventional submarine for military fleets to exercise anti-submarine warfare. The AUV actively emits amplified versions of received sonar pulses to create the illusion of being a larger object. READ MORE

  4. 3. Exploratory study on Additive Manufacturing in Urban mobility

    University essay from

    Author : Kaustubh Deshmukh; [2023]
    Keywords : ;

    Abstract : This thesis report presents a comprehensive study on the design and development of an Additively manufactured Unit cell for car door panels, aiming to enhance impact resistance and reduce noise transmission to the vehicle cabin. In order to accomplish these goals, the study focuses on combining two novel techniques namely quasi-zero stiffness (QZS) structures and phononic crystals (both scattering and locally resonating type).

  5. 4. Automatic loose gravel condition detection using acoustic observations

    University essay from Högskolan Dalarna/Institutionen för information och teknik

    Author : Gionian Kyros; Elias Myrén; [2022]
    Keywords : Sound Classification; Supervised Machine Learning; Gravel roads assessment; SVM; Random Forest; Ensemble of bagged trees; Sound feature extraction;

    Abstract : Evaluation of the road's condition and state is essential for its upkeep, especially when discussing gravel roads, for the following reasons, among other. When loose gravel is not adequately maintained, it can pose a hazard to drivers, who can lose control of their vehicle and cause accidents. READ MORE

  6. 5. NVH analysis and optimization of electric powertrain

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Anujit Dafle; [2022]
    Keywords : Electric powertrain; Gear whine; Noise Vibration Harshness NVH ; Elektrisk drivlina; kuggvin; buller och vibrationer;

    Abstract : With increasing focus on electromobility many companies are developing vehicles powered by an electric energy source. Previously, engines used to be the most prominent source of noise in a traditional Internal Combustion Engine (ICE) vehicle. READ MORE
