  1. 1. Heart Rate Measurement using a 60 GHz Pulsed Coherent Radar Sensor

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Melina Al Nasser; Linn Gromert; [2022]
    Keywords : Signal processing; EKG; Heart rate; Radar sensor; Neural network; Acconeer; Technology and Engineering;

    Abstract : Heart rate is today measured in various ways, but they all include contact with the skin. Measuring heart rate contactless would be a more efficient method in healthcare and would also benefit people suffering from skin problems. It has been proven that it is possible to use radar to measure heart rate. READ MORE

  2. 2. Exploiting Spatial Redundancy and Approximate Computing for Area Efficient Image Compression

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

    Author : Saurav Arjun; [2022]
    Keywords : Image Compression; VLSI; Spatial redundancy; DCT; Compression; System Verilog; Technology and Engineering;

    Abstract : Owing to the intensive computation involved in the Discrete Cosine Transform during image com- pression, the design of the efficient hardware architectures for fast computation of the transform has become imperative, especially for real-time applications. Although fast computation techniques have been able to minimise the hardware computation complexity to a certain limit, they could further extend the research to figure out the interesting approaches which can be implemented on applications where power, speed and area are crucial factors to determine the performance of the system.

  3. 3. The influence of working memory on the quality of linguistic predictions during speech understanding in adverse listening conditions : Comparing cortical responses using MEG

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Karin Allander; [2022]
    Keywords : Speech understanding; Linguistic predictions; Working memory; ELU-model;

    Abstract : Speech understanding is a fundamental human ability that enable flexible communication among individuals. Understanding natural speech in normal conditions is a fast and automatic process. It is facilitated through integration between prior knowledge about a speech signal and multimodal speech inputs.

  4. 4. Kriging radio environment map construction

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Erik Lundqvist; [2022]
    Keywords : Kriging; Radio environment; Statistics; Inverse distance weighting;

    Abstract : With the massive increase in usage of some parts of the electromagnetic spectrum during the last decades, the ability to create real time maps of signal coverage is now more important than ever before. This Masters project is designed to test two different methods of generating such maps with a one second limit to processing time. READ MORE

  5. 5. Organization of Electronic Dance Music by Dimensionality Reduction

    University essay from Umeå universitet/Institutionen för datavetenskap

    Author : Victor Tideman; [2022]
    Keywords : Dimensionality Reduction; Digital Signal Processing; Similarity; Music;

    Abstract : This thesis aims to produce a similarity metric for tracks of the genre: Electronic Dance Music, by taking a high-dimensional data representation of each track and then project it to a low-dimensional embedded space (2D and 3D) by applying two Dimensionality Reduction (DR) techniques called t-distributed stochastic neighbor embedding (t-SNE) and Pairwise Controlled Manifold Approximation (PaCMAP). A content-based approach is taken to identify similarity, which is defined as the distances between points in the embedded space. READ MORE
