  1. 1. 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

  3. 2. Automatic Sleep Scoring To Study Brain Resting State Networks During Sleep In Narcoleptic And Healthy Subjects : A Combination Of A Wavelet Filter Bank And An Artificial Neural Network

    University essay from Linköpings universitet/Institutionen för medicin och hälsa

    Author : Federica Viola; [2014]
    Keywords : Automatic Sleep Scoring; Discrete Wavelet Transform; Filter Bank; Artificial Neural Network; Resting State Networks; Narcolepsy.;

    Abstract : Manual sleep scoring, executed by visual inspection of the EEG, is a very time consuming activity, with an inherent subjective decisional component. Automatic sleep scoring could ease the job of the technicians, because faster and more accurate. READ MORE

  4. 3. Wavelet Based SPIHT Compression for DICOM Images

    University essay from Linnéuniversitetet/Institutionen för datavetenskap, fysik och matematik, DFM

  5. 4. Signal Processing Using Wavelets in a Ground Penetrating Radar System

    University essay from Institutionen för systemteknik

    Author : Thomas Andréasson; [2003]
    Keywords : Technology; wavelet; wavelet packet; feature extraction; mine detection; TEKNIKVETENSKAP;

    Abstract : This master's thesis explores whether time-frequency techniques can be utilized in a ground penetrating radar system. The system studied is the HUMUS system which has been developed at FOI, and which is used for the detection and classification of buried land mines. The objective of this master's thesis is twofold.
