  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. 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

  4. 4. Extended analysis of a pseudo-spectral approach to the vortex patch problem

    Abstract : A prestudy indicated superior accuracy and convergence properties of apseudo-spectral method compared to a spline-based method implemented byCòrdoba et al. in 2005 when solving the α-patches problem. READ MORE

  5. 5. An Application of the Continuous Wavelet Transform to Financial Time Series

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

    Author : Klas Eliasson; [2018]
    Keywords : Wavelets; Continuous Wavelet Transform; CWT; Financial Time Series; Currency Trading; Technology and Engineering;

    Abstract : Wavelet theory, which shares fundamental concepts with windowed Fourier analysis, introduces the notion of scale in an effort to aid in joint time-frequency analysis. Having century-old roots, much of the essential research on the subject of wavelets was conducted during the 1970s and 1980s. READ MORE
