  1. 1. 64-point FFT Instruction Implementation and Evaluation on a Microcode Programmable Processor

    University essay from Linköpings universitet/Institutionen för systemteknik; Linköpings universitet/Tekniska fakulteten

    Author : Yongjun Liu; Zejun Huang; [2022]
    Keywords : FFT; Instruction design;

    Abstract : Fast Fourier Transform is an efficient algorithm for computing the Discrete Fourier Transform (DFT) and one of the most important algorithms used in many digital signal processing applications over decades. This thesis presents an efficient implementation method of a 32-bit complex number 64-point FFT instruction on a micro-programmable processor. READ MORE

  3. 2. Arbitrary Decimation for High Sample Rates, Algorithm Design and FPGA implementation

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

    Author : Fredrik Peterson; [2019]
    Keywords : Sample Rate Conversion; Decimation; Farrow Structure; Farrow Filter; Technology and Engineering;

    Abstract : This master thesis investigates how to perform irrational decimation, the process of reducing the sample rate of a signal, for high throughput systems. The thesis work consists both an algorithmic part and an implementation part. READ MORE

  4. 3. Analysis of forklift data – A process for decimating data and analyzing fork positioning functions

    University essay from Linköpings universitet/Statistik och maskininlärning

    Author : Gustav Sternelöv; [2017]
    Keywords : Statistics; CAN data; autoregressive; AR; decimation; signal processing; bayesian hierarchical model;

    Abstract : Investigated in this thesis are the possibilities and effects of reducing CAN data collected from forklifts. The purpose of reducing the data was to create the possibility of exporting and managing data for multiple forklifts and a relatively long period of time. READ MORE

  5. 4. Interactive visualization of taxi data using heatmaps

    University essay from Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska högskolan

    Author : Albin Törnqvist; [2016]
    Keywords : Information visualization; Heat maps; Taxi data; Positioning data; Data decimation; Data crunching; Web development; Geographical;

    Abstract : This master thesis report presents the development of a geographical visualization system using taxi data. The system uses a large data base from a taxi company that have previously never used the data for visualization purposes. READ MORE

  6. 5. Automatic Mesh Repair

    University essay from Informationskodning

    Author : Agnes Larsson; [2013]
    Keywords : Automatic mesh repair; Manifold dual contouring; Jacobi rotations; Octree;

    Abstract : To handle broken 3D models can be a very time consuming problem. Several methods aiming for automatic mesh repair have been presented in the recent years. This thesis gives an extensive evaluation of automatic mesh repair algorithms, presents a mesh repair pipeline and describes an implemented automatic mesh repair algorithm. READ MORE
