  1. 1. Prediction of Plastic Fragments in Recycled Paper Using Near-Infrared Spectroscopy

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Fidan Alieva; [2023]
    Keywords : Near-infrared spectroscopy; paper packaging; barrier materials; recycling; multivariate data analysis; Nära-infraröd spektroskopi; pappersförpackningar; barriärmaterial; återvinning; multivariat dataanalys;

    Abstract : 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. READ MORE

  3. 2. Comparison of data analysis methods KMSProTF and MsDEMPCA using Magnetotelluric data

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Einar Valtersson; [2020]
    Keywords : MV-analysis; Magnetotellurics; MsDEMPCA;

    Abstract : 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. READ MORE

  4. 3. Determination of the Degree of Oxidation in Dialdehyde Cellulose Using Near Infrared Spectroscopy

    University essay from Karlstads universitet/Avdelningen för kemiteknik

    Author : Carl-Magnus Brandén; [2017]
    Keywords : dialdehyde cellulose; DAC; NIR; periodate oxidation; multivariate analysis; degree of oxidation; dialdehydcellulosa; DAC;

    Abstract : 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.

  5. 4. Measurement of Reduction Efficiency in Green Liquor Using a NIR Spectrometer

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Josef Persson; [2016]
    Keywords : NIR; spectrometry; green liquor; reduction efficiency; PLS; PCA; multivariate calibration;

    Abstract : 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.

  6. 5. Valuation of spread options using the fast Fourier transform under stochastic volatility and jump diffusion models

    University essay from Lunds universitet/Nationalekonomiska institutionen

    Author : Max Andersson; [2015]
    Keywords : Fast Fourier transform; Spread options; Derivatives pricing; Stochastic volatility; Jump diffusion; Business and Economics; Mathematics and Statistics;

    Abstract : 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). READ MORE
