1. 21. 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

3. 22. 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.

4. 23. Flow Classification of Encrypted Traffic Streams using Multi-fractal Features

   University essay from Linköpings universitet/Institutionen för datavetenskap

   Author : Erik Areström; [2018]
   Keywords : ;

   Abstract : The increased usage of encrypted application layer traffic is making it harder for traditional traffic categorization methods like deep packet inspection to function. Without ways of categorizing traffic, network service providers have a hard time optimizing traffic flows, resulting in worse quality of experience for the end user. READ MORE

5. 24. 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.

6. 25. Otolith morphology of sprat (Sprattus sprattus) along the Swedish west coast

   University essay from SLU/Dept. Of Aquatic Resources

   Author : Francesco Saltalamacchia; [2018]
   Keywords : European sprat; Otolith; shape analysis; wavelet;

   Abstract : The population structure of sprat (Sprattus sprattus) in the Swedish Kattegat – Skagerrak has been at present not well investigated, and the boundaries between the management unit in this region and the larger stock occurring in the North Sea are also highly uncertain, posing issues to the successful management of the stock in this area. In this study, variations in otolith shape among several samples from the Swedish west coast, southern North Sea and Norwegian fjords north of Bergen were studied to investigate the effectiveness of shape analysis for characterise the population structure in the study area, and evaluate whether differences could be used to assign individual fish to their origin.
