  1. 16. Control and balancing of a small vehicle with two wheels for autonomous driving

    Master-uppsats, KTH/Fordonsdynamik; KTH/Fordonsdynamik

    Författare :Saro Batmanian; Pasam Naga; [2019]
    Nyckelord :Inverted pendulum; PID controller; Pole placement method; LQR; Hoverboard; Segways; Prototype; Arduino board; Gyroscope; Accelerometer; BLDC motor controllers; EPOS motor controllers; Embedded systems and control and bluetooth remote.;

    Sammanfattning : Control and balancing of an inverted pendulum has gained a lot of attention over the past few decades due to its unstable properties. This has become a great challenge for control engineers to verify and test the control theory. LÄS MER

  2. 17. How Stellar Tides Affect Planet Evolution

    Kandidat-uppsats, Lunds universitet/Astronomi

    Författare :Madison Green; [2019]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Planets that orbit their host star closely experience tidal forces due to the strength of gravity not being uniform all over the planet. This leads to effects such as tidal spin synchronization, tidal eccentricity damping and tidal semi-major axis damping. LÄS MER

  3. 18. The effect of Mercosur on trade : How have Mercosur effected trade between member countries?

    Kandidat-uppsats, Södertörns högskola/Institutionen för samhällsvetenskaper; Södertörns högskola/Institutionen för samhällsvetenskaper

    Författare :Besrat Habtu; Intisar Ahmed; [2019]
    Nyckelord :International trade theory; Mercosur; free trade agreement; Gravity model; Linder effect; export and import; trade flows;

    Sammanfattning : This thesis examines whether there is an effect of the Mercosur free trade agreement on export and import between member countries. The study uses an extended gravity model framework on a panel data between the years 1975 to 2017 for 34 countries, including the member countries. Two different regressions were run using OLS and country fixed effect. LÄS MER

  4. 19. Koncept för materialpresentation till kollaborativ robot

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Jonathan Sandström; [2019]
    Nyckelord :;

    Sammanfattning : This report is based on a bachelor’s thesis for mechanical engineers at Umeå University, done during the spring of 2019. The thesis is done at the request of and in cooperation with Sanmina SCI-AB in Örnsköldsvik. LÄS MER

  5. 20. Simulation of a Rotational Brake System Regulated by Change in Angular Deceleration

    Master-uppsats, Lunds universitet/Mekanik

    Författare :Dennis Stenson; Marko Sarajärvi; [2019]
    Nyckelord :Technology and Engineering;

    Sammanfattning : A fully mechanical rotational brake system activated and regulated by rate of change in angular velocity has been developed by Brillianze Sweden AB. Its field of usage is currently limited and is to be expanded upon. Therefore new models were made to perform multibody dynamics simulations in Adams/View. LÄS MER
