1. Prediction of Plastic Fragments in Recycled Paper Using Near-Infrared Spectroscopy
Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : Sustainability has gained a lot of attention in the field of research. Researchers and consumers both prioritize sustainability and environmental issues over previously dominant materials, such as plastic. Packaging and disposable items that used to be made of plastic have largely been replaced with paper. LÄS MER
2. Comparison of data analysis methods KMSProTF and MsDEMPCA using Magnetotelluric data
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : In this work two ways of processing controlled-source magnetotelluric (MT) data were tried and compared against each other. The aim was to evaluate the differences between a multivariate-based processing method to a bivariate processing method. The software KMSProTF represents conventional processing using bivariate and robust statistics. LÄS MER
3. Determination of the Degree of Oxidation in Dialdehyde Cellulose Using Near Infrared Spectroscopy
Uppsats för yrkesexamina på avancerad nivå, Karlstads universitet/Avdelningen för kemiteknikSammanfattning : The purpose of this thesis work was to investigate possible in-, on- or at-line methods to determine the degree of oxidation in dialdehyde cellulose. Several technologies were reviewed which led to a feasibility study into a possible on-line or at-line method using near infrared spectroscopy for determining the degree of oxidation in wet dialdehyde cellulose.

4. Measurement of Reduction Efficiency in Green Liquor Using a NIR Spectrometer
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : Domsjö Fabriker has earlier installed a Near Infrared (NIR) spectrometer after one of their recovery boilers. The purpose is to monitor the reduction efficiency of the boiler and later do process optimization. In this work calibration models for the instrument have been created. 108 green liquor samples have been extracted. LÄS MER
5. Valuation of spread options using the fast Fourier transform under stochastic volatility and jump diffusion models
Master-uppsats, Lunds universitet/Nationalekonomiska institutionenSammanfattning : Spread options have become very popular in basically every sector of the financial markets, although the pricing of these derivatives still remains a challenge. In this thesis we examine the pricing of spread options using the fast Fourier transform (FFT). LÄS MER
