  1. 1. Achieving Optimal Alignments of IR Source and Detector in Waveguide Based Gas Sensor

    University essay from KTH/Medicinteknik och hälsosystem; KTH/Medicinteknik och hälsosystem

    Author : Sefik Güler; Agbai Randolph Agwu; [2020]
    Keywords : Non-dispersive infrared technology; microelectromechanical systems; infrared light; electromagnetic spectrum; gas sensor; light emitting diode; photodiode detector; Icke-dispersiv infraröd teknologi; mikroelektromekaniska system; infrarött ljus; elektromagnetiskt spektrum; gassensor; lysdiod; fotodioddetektor;

    Abstract : I takt med att tekniken för mikroelektromekaniska system utvecklas uppkommer det nya områden för tillämpning. Ett område är inom gassensorer där icke-dispersiv infraröd strålning används genom att mäta absorptionen hos olika gaser för att bestämma mängden av en specifik gas i luften. READ MORE

  2. 2. Lyman Continuum Radiation from Intermediate-Mass Black Holes : An Estimation of the Contribution of LyC Radiation from IMBHs in z~3 Galaxies

    University essay from Uppsala universitet/Observationell astrofysik

    Author : Marika Ljungberg; [2020]
    Keywords : intermediate-mass black holes; cosmic reionization; high-redshift galaxies;

    Abstract : This thesis concerns the cosmic reionization of the intergalactic medium in the high redshift universe and, in particular, is a first approach to examine what role intermediate mass black holes (IMBHs) play in this cosmic age. Unexpectedly high values of hydrogen ionizing radiation, compared to current models, have been reported from galaxies at redshift ~3 (used as stand-ins for galaxies at the age of reionization), and thus these models need revision, potentially by adding effects of IMBH content in the galaxies.

  3. 3. Heat stress at preschool yards. A mixed-method geographical study in Gothenburg, Sweden.

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Oskar Bäcklin; [2019-10-30]
    Keywords : ;

    Abstract : As climate change is predicted to generate higher temperature and more frequentheat waves and extreme temperature events in Sweden, issues related to heat willbe more accentuated in the future. Children are both vulnerable to heat and spendmuch of their time outdoors at preschool yards. READ MORE

  4. 4. Classification of High Risk Prostate Cancer using Deep Learning

    University essay from Lunds universitet/Matematik LTH

    Author : Elin Olofsson; [2019]
    Keywords : Prostate Cancer; CNN; Deep Learning; PRIAS; Active Surveillance; Digital Pathology; Mathematics and Statistics;

    Abstract : Prostate cancer is one of the most common types of cancer for men, making proper diagnostic essential. Using machine learning as a tool to help in digital pathology has become increasingly popular and helps to limit the high intra observer variability between pathologists. READ MORE

  5. 5. Autonomous Counterbalance Forklift : Autonomous forklift capable of transporting pallets

    University essay from KTH/Skolan för industriell teknik och management (ITM); KTH/Skolan för industriell teknik och management (ITM)

    Author : Ludvig Boczar; Felix Myrsten; [2019]
    Keywords : mechatronics; forklift; autonomous; line follower.; mekatronik; motviktstruck; autonom; linjeföljare.;

    Abstract : This thesis explored the possibility to use line following technology to automate forklifts in a warehouse scenario. This was done to reduce the need for staff to always be present in the warehouse. A prototype forklift was constructed with three wheels, where driving and steering was done by the rear wheel.
