Analysis of low Frequency content from the Circulatory System
(Master thesis, 2016)This thesis has investigated the low frequency content from the cardiovascular system. Three different signals; heart rate variability(HRV), blood pressure(BP) and a flow signal of the blood(Laser doppler flow, LDF) all ... -
Construction of a GaN class AB power Amplifier with digital pre distortion
(Master thesis, 2016)The number of wireless devices in the world is growing rapidly. One of the most crucial parts of a wireless communication system is the power amplifier. This creates a huge demand, and a big interest for power amplifiers, ... -
Diffusion-Based Molecular Communications in Wireless Pacemakers
(Master thesis, 2016)Molecular communications is a novel communication technique that has many advantages over the traditional radio frequency technologies used in body area medical applications. It is based on the body`s own biological ... -
Fast Non-Rigid Registration Using Polynomial Expansion with Diffeomorphic Constraints Applied to Cardiac Ultrasound Volumes
(Master thesis, 2017)This thesis attempted to develop a fast, non-rigid, diffeomorphic image registration implementation and was written as a continuation of a project that was completed during the fall of 2016 \cite{prosjekt_oppgave} which ... -
High resolution spectral estimation for radar in a pipe
(Master thesis, 2017)In this project I have studied and evaluated several high resolution spectral estimation algorithms to improve accuracy and robustness in a FMCW radar tank gauge (RTG). The system parameters are taken from KONGSBERG's ... -
Implementation and Assessment of Supersonic Shear Imaging Techniques
(Master thesis, 2017)Shear Wave Elastography (SWE) is an ultrasound modality which can measure tissue elasticity quantitatively. It provides valuable diagnostic information in addition to conventional ultrasound modalities. SWE has been shown ... -
Implementation of a System for Automatic Speech Recognition of Child Speech
(Master thesis, 2016)Most speech recognizers today are trained on adult speech corpora. Child speech differ from adult speech on several areas. These differences cause severe degradation in the performance of an ASR system developed for adult ... -
Machine Learning of Circulatory Oscillations in Cardiac Surgical Patients
(Master thesis, 2016)The human circulatory system is a complex organ system, with multiple feedback and feedforward mechanism for regulation. When global circulatory variables are assessed, these exhibit distinct oscillatory patterns with ... -
Open Set Speaker Identification
(Master thesis, 2017)Digital assistants that communicate through speech are one of the new technologies that have emerged this decade. Progress in the field of speaker recognition have opened up possibilities for having digital assistants for ... -
QoE Aspects of Motion Tracking in Sensor Based Digital Storytelling
(Master thesis, 2016)Storytelling is, and always will be, an important part of cultures all around the world. It is used for education, to entertain and to preserve history. Sen- sor based digital storytelling is a new concept within Interactive ... -
Speech Enhancement with Deep Neural Networks
(Master thesis, 2016)This master thesis describes the implementation and evaluation of a promising approach to speech enhancement based on deep neural networks. A baseline system was imple- mented and trained using noisy data synthesized by ... -
Ultrasonic Imaging through Solids
(Master thesis, 2016)Ultrasonic testing is a widely used method, in the industry, for non destructive inspection of materials. The most commonly used technique is the pulse-echo technique where ultrasound is introduced into a test object and ... -
Using Deep Learning in Hearing Aids
(Master thesis, 2016)The aim of this masters thesis is to investigate if deep neural networks and deep learning can work as an alternative for existing hearing aids. Traditional hearing aids are limited to compensate for attenuation losses and ... -
Waveform Design for Software Defined Multifunctional RF Systems
(Master thesis, 2017)In this thesis, a study of multifunctional radio frequency (RF) systems implementing radar, communication, and electronic warfare (EW) is presented. Development of low cost and highly adaptable software defined radios ... -
Wireless Video Capsule Endoscopy - Adaptive Coding for Parameters Update and Low Complexity Region-of-Interest Encoding
(Master thesis, 2016)Wireless capsule endoscopy (WCE) is a non-invasive diagnostic method to investigate diseases in the human gastrointestinal (GI) tract. Specifically, the WCE allows for physicians to visually inspect the GI tract of the ...
