  1. 1. Robot Condition Monitoring and Production Simulation

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

    Author : Martin Karlsson; Fredrik Hörnqvist; [2018]
    Keywords : Robot Condition Monitoring Production Simulation SKF ABB IRB 6600 Vibration;

    Abstract : The automated industry is in a growing phase and the human tasks is increasingly replaced by robots and other automation solutions. The increasing industry entails that the automations must be reliable and condition monitoring plays an important role in achieving that ambition. READ MORE

  2. 2. Fractional Fourier Transform and Scaling Problem in Signals and Images

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Achyutha Ramarao Maddukuri; [2018]
    Keywords : Dynamic scaling; Fractional Fourier transform; Fourier transform; Pattern recognition; Signal and Image change detection;

    Abstract : Context: We identify a material or thing that can be seen and touched in the world as having structures at both coarser and finer levels of scale. Scaling problem presents in a branch of science concerned with the description, prediction understanding of natural phenomena and visual arts. READ MORE

  3. 3. One Million-Point FFT

    University essay from Linköpings universitet/Datorteknik; Linköpings universitet/Datorteknik

    Author : Tobias Mellqvist; Hans Kanders; [2018]
    Keywords : Large FFT; FFT; Cooley–Tukey; SDF; Binary tree; FPGA; triangular matrix;

    Abstract : The goal of this thesis has been to implement a hardware architecture for FPGA that calculates the fast Fourier transform (FFT) of a signal using one million samples. The FFT has been designed using a single-delay feedback architecture withrotators and butterflies, including a three-stage rotator with one million rotation angles. READ MORE

  4. 4. Analysing Memory Performance when computing DFTs using FFTW

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

    Author : Andreas Heiskanen; Erik Johansson; [2018]
    Keywords : fftw; discrete fourier transform; fast fourier transform; hpc; perf; cache; memory analysis;

    Abstract : Discrete Fourier Transforms (DFTs) are used in a wide variety of dif-ferent scientific areas. In addition, there is an ever increasing demand on fast and effective ways of computing DFT problems with large data sets. The FFTW library is one of the most common used libraries when computing DFTs. READ MORE

  5. 5. Studies on Radiation-induced Defects in InP/InAsP Nanowire-based Quantum Disc-in wire Photodetectors

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Ebrahim Mansouri; [2018]
    Keywords : InP InAsP; QDiscs-in-wire; photodetectors; proton irradiation; Photocurrent; I-V characteristics;

    Abstract : Photodetectors are used in many applications such as digital and thermal cameras or in solar panels. They can also be designed to detect the omnipresent high-energy radiation/particles, and for radiation imaging in biomedical applications. READ MORE
