  4. 3. 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.

    University essay from KTH/Matematisk statistik

    Author : Johannes Jeppsson; [2017]
    Keywords : ;

    Abstract : This report was carried out at Gleechi, a Swedish start-up company working with implementing hand use in Virtual Reality. The thesis presents hand models used to generate natural looking grasping motions. One model were made for each of the thirty-three different grasp types in Feix’s The GRASP Taxonomy. READ MORE
