    Abstract : This bachelors thesis presents a vision based control system for the quadrotor aerial vehicle,Crazy ie 2.0, developed by Bitcraze AB. The main goal of this thesis is to design andimplement an o-board control system based on visual input, in order to control the positionand orientation of the vehicle with respect to a single ducial marker.

  3. 2. Preventing Gender-Based Violence Post Disasters : Building the capacity of humanitarian actors in the Philippines to engage with men and boys to reduce the risks of perpetration of violence

    University essay from Uppsala universitet/Teologiska institutionen

    Author : Jenny Molin; [2018]
    Keywords : gender-based violence; prevention; engaging men and boys; masculinities; humanitarian action; disasters; the Philippines;

    Abstract : Gender based violence (GBV) is a global public health issue and a major feature in humanitarian emergencies. However, the phenomenon is not inevitable and can be predicted and prevented. READ MORE

  4. 3. Prospects for a sustainable agricultural transformation in Ethiopia : green niche actors navigating a challenging institutional context

    University essay from Stockholms universitet/Stockholm Resilience Centre

    Author : Linn Järnberg; [2016]
    Keywords : Ethiopia; transformation; agricultural systems; sustainability; development pathways; governance; narratives; agency; action strategies;

    Abstract : Identifying pathways of agricultural development that enable substantial productivity improvements is of prime importance for food security and human development across Sub-Saharan Africa. To ensure long-term welfare for its people and landscapes, it is imperative that such agricultural transformations are environmentally sustainable. READ MORE

  5. 4. Symmetries of the Point Particle

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Alexander Söderberg; [2014]
    Keywords : symmetries; spin; classical physics; classical field theory; action; smooth spinning particle; pauli-lubanski; noether; theorem; poincare group; lorentz group; galilean transformations; relativistic; equations of motion; boost; rotation; translation; quantization; bosonic string; rigid particle; momentum; momenta; generators;

    Abstract : We study point particles to illustrate the various symmetries such as the Poincaré group and its non-relativistic version. In order to find the Noether charges and the Noether currents, which are conserved under physical symmetries, we study Noether’s theorem. READ MORE

  6. 5. Trajectory Planning for a Rigid Body Based on Voronoi Tessellation and Linear-Quadratic Feedback Control

    University essay from KTH/Optimeringslära och systemteori

    Author : Hans Flodin; Gustav Friberg; Fredrik Wahlberg; [2012]
    Keywords : ;

    Abstract : When a rigid body moves in 3-dimensional space, it is of interest to nd a trajectory such that it avoids obstacles. With this report, we create an algorithm that nds such a trajectory for a 6- DOF rigid body. For this trajectory, both the rotation and translation of the rigid body are included. READ MORE
