1. Calculating scattering amplitudes in φ3 and Yang-mills theory using perturbiner methods
University essay from Uppsala universitet/Teoretisk fysikAbstract : We calculate tree-level scattering amplitudes in φ^3 theory and Yang-Mills theory by means of the perturbiner expansion. This involves solving the Euler-Lagrange equations of motion perturbatively via a multi-particle ansatz, and using Berends-Giele recursion relations to extract the solution from simple on-shell data.

2. The Hanging Rope: A Convex Optimization Problem in the Calculus of Variations
University essay from Lunds universitet/Matematik LTHAbstract : We study the problem first introduced by Verma and Keller in 1984 of how to taper a heavy rope such that its elongation is minimized. The problem is stated as an optimization problem of a functional J[w]. Specifically we provide a proof of optimality for the solution using traditional convex optimization techniques. READ MORE

3. Development and Implementation of a Mass Balancing System for CubeSat Attitude Hardware-in-the-Loop Simulations
University essay from Luleå tekniska universitet/RymdteknikAbstract : Spacecraft simulator platforms can simulate the microgravity environment of space on Earth, for the purposes of testing the Attitude and Orbit Control Subsystem of satellites. In order to do this, the satellite is mounted on a bench and the combined center of mass of this assembly is controlled by a series of moving masses. READ MORE

4. Concise Modeling of Humanoid Dynamics
University essay from Högskolan i Halmstad/Akademin för informationsteknologiAbstract : Simulation of mechanical systems like walking robots, is an essential part in developingnew and more applicable solutions in robotics. The increasing complexity of methodsand technologies is a key challenge for common languages. That problem creates a needfor flexible and scalable languages. READ MORE

5. Haptic Servo System
University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)Abstract : A ”Haptic servo system” is here understood as a servo system whereforces from a controlled system are fed back to an operator. This thesis workis a design work where the work among other things comprises the choice ofsuitable motors, one for operating the beam and another one for operatingthe steering wheel. READ MORE
