  1. 1. Deep Learning for Deep Water: Robust classification of ship wakes with expert in the loop

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Igor RYAZANOV; [2020-10-06]
    Keywords : machine learning; deep learning; pattern recognition; acoustic data analysis; shipping data; data augmentation; noise robustness; classification with data imbalance; expert-in-the-loop framework;

    Abstract : This work examines the applicability of the deep learning models to pattern recognitionin acoustic ocean data. The features of the dataset include noise, data scarcityand the lack of labeled samples. A deep learning model is proposed for the task ofautomatic wake detection. READ MORE

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Daniel Gutiérrez; [2020]
    Keywords : Industrial gas turbines; Combustion instabilities; Computational fluid dynamics; Acoustics; COMSOL Multiphysics; Flame transfer function;

    Abstract : Many industries have entered a new global phase which takes the environment in mind. The gas turbine industry is no exception, where the utilization of green fuels is the future to spare the environment from carbon dioxide and NOx emissions. READ MORE

  3. 3. Acoustic Soil-Rock Probing : A Case Study in Gubbängen

    University essay from KTH/Jord- och bergmekanik

    Author : Helen Kalm; [2019]
    Keywords : soil-rock probing; spectrogram; frequency analysis;

    Abstract : Soil-rock probing (Jb-probing) is the most common probing method in Sweden. Due to the penetration capacity of the Jb-probing it can be performed in both soil and rock. However, the capacity also results in inherent limitations and uncertainties, such as the difficulty identifying the soil layer sequences of soft soils. READ MORE

  4. 4. A Linear, Wide-band, Low-Power Receiver for Narrowband- Internet of Things (NB-IoT)

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Rohan Raghunath; Ghanashyam Ravindranath Prabhu; [2018]
    Keywords : NB-IoT; FTNC; Harmonic rejection; N-path filtering; RX Front End; Low power; Wide-band; Passive mixer; Current mode; Technology and Engineering;

    Abstract : Advancement of technology with the aid of new application, wireless communication has grown rapidly in the past two decades. Recently, in the wireless communication industry, Narrowband- Internet of Things (NB-IoT) is being discussed by everyone, as the most important emerging technology of the day. READ MORE

  5. 5. Acoustic Analysis of Wave-Guide and MEMS Microphone in Camera Including Thermoviscous Losses

    University essay from Blekinge Tekniska Högskola

    Author : Karolis Poskus; [2018]
    Keywords : ;

    Abstract : Today Micro Electrical Mechanical Systems (MEMS) microphones are available in a range of electronic consumer products such as smart phones, tablets, smartwatches and surveillance cameras. The MEMS microphones are usually attached to a circuit board with a hole that lets sound propagate through, as well as additional wave-guides which alter the MEMS microphones original frequency response.
