  1. 1. Kinematic Design of a 3-DoF Robot Manipulator for Automatic handling of Build-Boxes

    M1-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Filip Jonsson; [2019]
    Nyckelord :Robotics;

    Sammanfattning : The goal of this project has been to make a prototype model of a 3-DOF PPM manipulator based on an old prototype for the purpose of moving heavy build boxes from a 3D-printer to an oven. The project was focused on the development of the kinematic model of the manipulator. LÄS MER

  2. 2. Performance monitoring of systems for airpuricationAuthor:Anders

    Uppsats för yrkesexamina på avancerad nivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Anders Gustafson; [2019]
    Nyckelord :;

    Sammanfattning : Wastewater treatment plants (WWTP) are often the cause of malodor. The compounds which are the main causes of the odor is hydrogen sulfide (H2S), ammonia(NH3), mercaptans (RSH) and volatile organic compounds (V OC) [1]. The odorous air can be analyzed to determine the concentration of the odorants. LÄS MER

  3. 3. Investigation into Melting Characteristics of Hydrogen-Reduced Iron Ore Pellets

    Master-uppsats, KTH/Materialvetenskap

    Författare :Hedda Pousette; [2019]
    Nyckelord :Iron Ore Pellets; Sulphur; Phosphorous; Slag; Hydrogen Gas; Järnmalmspellets; Svavel; Fosfor; Slagg; Vätgas;

    Sammanfattning : What kinetic and thermodynamic characteristics are established in a melt of hydrogen-reduced iron ore pellets? The pellets contain self-fluxing slag components which upon melting form an initial slag. Refining capabilities of this slag, such as dephosphorization power, are investigated in a lab-scale vertical furnace. LÄS MER

  4. 4. Oral fluoride retention after use of mouth rinses with different fluoride content.

    Master-uppsats, Malmö universitet/Odontologiska fakulteten

    Författare :Lisa Hansen; Alexander Stime; [2019]
    Nyckelord :Fluoride;

    Sammanfattning : Abstract Objective: The purpose of the study is to investigate how fluoride content in saliva depends on different fluoride mouth rinses: 1450 ppm, 910 ppm, 225 ppm and to compare a new 1450 ppm fluoride mouth rinse with the other concentrations. Material and method: The study included 17 subjects which rinsed with three different mouth rinses, A (225 ppm), B (1450 ppm) and C (910 ppm) at three different times. LÄS MER

  5. 5. Analysis of a mathematical model in Python for geographical disaggregation of freight growth rates based on the pivot-point method

    Master-uppsats, KTH/Optimeringslära och systemteori

    Författare :Karl Hernebrant; [2019]
    Nyckelord :;

    Sammanfattning : One of the tasks for the Swedish Transport Agency, Trafikverket, is to provide traffic forecasts. To do this, a number of different forecast models are used, where Samgods is a nationally estimated model, where the quality of the results gets more unstable the more disaggregated level you are looking at.
