  1. 16. Attitude control using ion thrusters for solar sailing from Low Earth Orbit to sub-L1

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Celeste Holm; Ida Ygland; [2022]
    Keywords : the sunshade project; geoengineering; solar sailing; attitude control; ion thrusters;

    Abstract : The purpose of the study is to evaluate the possibility of using gridded ion thrusters as a means of attitude control for a solar sail as a part of the sunshade project, which aims to place 10^8 solar sail sunshade spacecraft, each with an area of about 10 000 m^2, at the Sun-Earth Lagrangian point L1 in order to reduce Earth's global temperature. Two types of solar sail sunshade spacecraft were studied. READ MORE

  3. 17. Combining output from MS-based proteomics search engines using spectrum predictors

    University essay from KTH/Proteinvetenskap

    Author : William Hadd; [2022]
    Keywords : Mass spectrometry; Proteomics; machine learning; search engines; Masspektrometri; Proteomik; Maskininlärning; Transformers; Sökmotorer;

    Abstract : Masspektrometri (MS) är en analysmetod som indikerar provers kemiska sammansättning. Provernas innehåll fragmenteras och joniseras, varefter jonernas förhållande mellan massa och laddning (m/z) och sammanlagda intensiteter mäts i form av ett masspektrum. READ MORE

  4. 18. Building an in-house spectral library using GCorbitrap HRMS

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Elias Kolsmyr; [2022]
    Keywords : Environmental contaminants; Plastic additives; Gas chromatography; High resolution mass spectrometry; Spectral library; MS-DIAL;

    Abstract : There are a great variety of environmentals contaminants, a lot of which are understudied asit is today. The aim of this study was to develop an in-house high-resolution spectral librarycontaining environmental contaminants, with focus on plastic additives. The spectral librarywould then be used to perform suspect screening on real sample extracts. READ MORE

  5. 19. Development and validation of sample clean-up using solid phase extraction prior oil spill fingerprinting

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Cheryl Loorents; [2022]
    Keywords : Oil spill; chemical fingerprint; solid phase extraction SPE ; development; validation.;

    Abstract : In a forensic investigation involving oil, a comparative analysis named oil spill fingerprinting between a source and an oil spill is normally performed. It is based on detecting a certain selection of biomarkers with gas chromatography (GC) coupled to mass spectrometry (MS) which are later divided into diagnostic ratios (DRs). READ MORE

  6. 20. Development and Use of System Modeler 6DOF Flight Mechanics Model in Aircraft Conceptual Design

    University essay from Linköpings universitet/Fluida och mekatroniska system

    Author : Niko Erä-Esko; [2022]
    Keywords : Aircraft Conceptual Design; Flight Mechanics; Modelling and Simulation;

    Abstract : This thesis presents a tool for conceptual design of a traditional configuration aircraft by using a parametric six degrees of freedom (6DOF) flight mechanics model implemented in the Modelica Language using Wolfram System Modeler. Being first only able to model and simulate the uncontrolled flight of an aircraft with fixed mass and centre of gravity (CG), and requiring detailed aerodynamic parameters as an input, the 6DOF model is improved by developing new features to reduce the number of required inputs while also increasing the data output of the simulations.
