1. 6. Time-frequency analysis of THz-time domain spectroscopy data

   University essay from Uppsala universitet/Avdelningen för systemteknik

   Author : Hugo Laurell; [2018]
   Keywords : ;

   Abstract : This text investigates THz-TDS signals in the time-frequency domain. Addi- tionally this text discusses the prospects of using time-frequency analysis to alleviate distortion in THz spectrographic characterizations induced by back- reflections in the free space electro optic sampling used in the THz time-domain spectroscopy detection scheme.

3. 7. Wavelet Analysis of Business Cycle Synchronization in Europe

   University essay from Lunds universitet/Nationalekonomiska institutionen

   Author : Glenn Nielsen; [2018]
   Keywords : wavelet analysis; business cycle synchronization; principal component analysis; Euro area; optimum currency area; Business and Economics;

   Abstract : Business cycle synchronization is an essential criterion for creating and maintaining an optimal currency area. In this paper, it is investigated whether this required criterion holds for the Euro area at different time horizons (short run, medium run and long run), and if the financial crisis of 2007-2008 influenced the degree of synchronization in Europe.

4. 8. Optical sensors for mechanomyography and tissue chromophores

   University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Author : Emil Ljungberg; [2013]
   Keywords : Physics and Astronomy;

   Abstract : The mechanomyogram (MMG) is a mechanical oscillations observable on the surface of the skin as a muscle contracts. Measurement of the MMG utilizing contact sensors with a weight greater than 6 g has proved to interfere with the measurement. Use of optical displacement sensors without direct contact to the skin would remove this deficiency. READ MORE

5. 9. Nonstationary feature extraction techniques for automatic classification of impact acoustic signals

   University essay from Datateknik

   Author : Yasemi Bekiroglu; [2008]
   Keywords : railway sleepers;

   Abstract : Condition monitoring of wooden railway sleepers applications are generallycarried out by visual inspection and if necessary some impact acoustic examination iscarried out intuitively by skilled personnel. In this work, a pattern recognition solutionhas been proposed to automate the process for the achievement of robust results. READ MORE
