Orbital
Orbital is a virtual reality gaming experience designed to explore the use of traditional narrative structure to enhance immersion in virtual reality. The story structure of Orbital was developed based on the developmental steps of 'The Hero's Journey,' a narrative pattern identified by Joseph …

Orbital transfer trajectory optimization
… rocket engines for spacecraft. Optimizing the orbital transfers for low thrust engines is significantly more complicated than optimizing transfers for impulsive engines because a continuous control law must be found and long integrations are necessary to determine whether the control law works …

Depth and orbital tuning : a new chronology of glaciation and nonlinear orbital climate change
It is suggested that orbital tuning casts a false light upon the chronology of glaciation and the understanding of the climatic response to orbital variations. By developing a new age-model, independent of orbital assumptions, a significant non-linear response to orbital forcing becomes evident in …

Next generation satellite orbital control system
… architectures for the Next Generation Satellite Orbital Control System (NG-SOCS) are developed from compiled system specifications and a review of existing technologies. From the developed architectures, the recommended architecture is selected based on real-world considerations that face …

Orbital order in iron-based superconductors
In this thesis, we propose that a ferro-orbital order, which breaks the degeneracy between the Fe $d_{xz}$ and $d_{yz}$ orbitals, is the effective cause of the structural and the magnetic transitions in the iron-based superconductors. We will discuss this orbital order in the framework of the …

Orbital Polarization in Relativistic Density Functional Theory
… an atom described by quantum numbers, spin (S), orbital (L), and total angular momentum (J) of its electrons. A set of guidelines, known as Hund's rules, discovered by Friedrich Hermann Hunds help us to determine the quantum numbers for the ground states of free atoms. The question ``to which …

Molecular Orbital Calculations on Electrophilic Aromatic Substitution
… emphasis has beer given to the use of molecular orbital calculations to calculate the energy of molecules, little has been achieved toward using molecular orbital theory on a dynamically changing system such as a chemical reaction. | The purpose of this work was to devise a method for calculating …

Planar Orbital Method for Surface Electronic Structures
The method is applied to the self-consistent electronic structural calculations of the Si(001) 2 x 1 surface with symmetric and buckled dimers, As/Si(001) 2 x 1 and Sb/Si(001) 2 x 1 surfaces with symmetric dimers, and the hydrogen-passivated Si(001) 2 x 1 surface, as well as the …

Stability and distributivity over orbital [infinity]-categories/
Let G be a finite group. The homotopy theory of topological spaces with an action of G has provided important applications in many parts of homotopy theory and geometry. An especially important role has been played by the so-called "norm maps". In this thesis we develop a characterization of the …

Orbital debris : drafting, negotiating, implementing a convention
… that while space may be infinite, Earth orbital space is a finite natural resource that must be managed properly. The problem we face with space pollution is complex and serious. The space treaties and conventions are not sufficient. They were drafted at the time of space exploration in …

Autonomous orbital rendezvous using angles-only navigation
… by developing various relative motion orbital trajectories. Chaser vehicle maneuvers designed to enhance the estimator's observability of the downrange distance to the target are considered. The target vehicle is assumed to be non-maneuvering and in a near-circular orbit. The modeled …
