Singular optimal atmospheric rocket trajectories
… of a vehicle in atmospheric flight in which a variable-thrust arc forms a part of the optimal trajectory. A two-parameter family of singular arcs was generated for time-range-fuel problems of an ascending rocket, using the modelling of Zlatskiy and Kiforenko. The short-term optimality of the …

Optimal finite-thrust Trans-Earth Injection (TEI) maneuvers for a Low Lunar Orbit (LLO) earth return mission
… Singular arcs that appear in a main engine variable thrust, fuel optimal trajectory are examined by applying the Bellman Pseudospectral method. The feasibility of using the CEV auxiliary engines in place of the main engines for the singular arc maneuver is also investigated.

Spacecraft Trajectory Optimization Suite (STOPS): Optimization of Low-Thrust Interplanetary Spacecraft Trajectories Using Modern Optimization Techniques
… State University, San Luis Obispo. Low-thrust spacecraft engines are becoming much more common due to their high efficiency, especially for interplanetary trajectories. The version of STOpS presented here optimizes low-thrust trajectories using the Island Model Paradigm with three …

Precision determination of the strong coupling constant
In this thesis we study the event shapes variable thrust. Event shape variables are observables that characterize the shape of the distribution of the final state particles of a reaction. We take advantage of the formalism of Soft Collinear Effective Theory (SCET), an effective theory of the strong …
