  1. 1. Real-time characterization of fuel by Near-Infrared spectroscopy : Quantitative measurements of moisture content, ash content, heating value, and elemental compositions in solid biofuel mixtures

    University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Author : Kajsa Edlund; Ali Ahmad Shahnawazi; [2021]
    Keywords : NIR; spectroscopy; solid biofuel mixtures; moisture content; ash content; heating value; elemental composition; boiler; CHP pant; CCS; CO2; emissions; NIR; spektroskopi; fasta biobränsleblandningar; fukthalt; ask innehåll; värmevärde; elementär komposition; panna; kraftvärmeverk; CCS; CO2; utsläpp;

    Abstract : The global energy demand supplies mainly from fossil fuels, which is neither sustainable nor environmentally friendly and aims to global warming. Therefore, both more investments in renewable energy sources such as bioenergy are required, as well as new technologies such as carbon capture and storage (CCS) to handle the emissions from existing combined heat and power (CHP) plants.

  3. 2. CONSTRUCTION EQUIPMENT FUEL CONSUMPTION DURING IDLING : Characterization using multivariate data analysis at Volvo CE

    University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Author : Mujtaba Hassani; [2020]
    Keywords : Idling condition; environmental effect; diesel fuel; machine learning; multivariate data analysis; partial least square regression; support vector machine regression; principal component analysis; principal component regression; correlation coefficient matrix; artificial neural network; exhaust emission reduction techniques; global warming; emission regulation; CO2 estimation techniques; Gaussian process regression;

    Abstract : Human activities have increased the concentration of CO2 into the atmosphere, thus it has caused global warming. Construction equipment are semi-stationary machines and spend at least 30% of its life time during idling. The majority of the construction equipment is diesel powered and emits toxic emission into the environment. READ MORE

  4. 3. Affärsmodeller hos skogsentreprenadföretag i norra Sverige och deras inverkan på lönsamhet

    University essay from SLU/Department of Forest Biomaterials and Technology (from 131204)

    Author : Ida Larsson; [2019]
    Keywords : skogsentreprenör; Business Model Canvas; framgångsfaktorer; PLS; Pearson korrelationsanalys; multivariat analys;

    Abstract : Det har rapporterats om bristande lönsamhet och stora variationer i lönsamhet hos svenska skogliga entreprenörer. Studier pekar på att den strukturella uppbyggnaden av företagen kan ha en inverkan. För att kartlägga och jämföra skillnader i företags affärsmodeller är Business Model Canvas (BMC) ett vanligt verktyg. READ MORE

  5. 4. Determination of fossil share in combustion of waste : Development of a novel method using NIR spectroscopy to predict the content of plastics in RDF-material

    University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Author : Christian Dahl; [2018]
    Keywords : NIR; Near infra-red; spectroscopy; chemometrics; waste material; fossil share;

    Abstract : Incineration of waste materials has become a common way to handle a worldwide increase of produced waste materials. The problem with waste as fuel is that the material is not homogeneous and include a mixture of fossils and renewables. READ MORE

  6. 5. Evaluation of stimulated reductivedechlorination in situ of chlorinatedsolvents at a site in Huddinge : using principal component analysis, partialleast square regression and degradation

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Karin Ljungberg; [2018]
    Keywords : Reductive dechlorination; DNAPL; stimulated bioremediation; chlorinated solvents; Reduktiv deklorering; DNAPLS; stimulerad biologisk behandling; klorerade lösningsmedel;

    Abstract : The method of using stimulated reductive dechlorination when remediating sites contaminated with chlorinated solvents is not unusual, but not many studies have been done on the overall process outside of a controlled environment. In order to investigate the process, principal component analysis (PCA) and partial least square (PLS) regression was used to identify the most important parameters for the degradation of the chlorinated solvents.
