Ultracold Molecular Structure and Collisions
… this dissertation, we discuss the structure and collisions of ultracold molecules in the presence of external magnetic fields. We explore these topics in four main projects. First, we study ultracold chemical reactions of triplet-state NaLi ( a 3 Σ + ) molecules with Na atoms in the presence of …

Diffraction in electron-proton collisions
Subject of this thesis is diffractive collisions of electrons and protons, i.e. collisions wher~ the proton remains intact or is slightly excited, and loses only a small fraction of its initial energy. Such processes can be described by the exchange of a pomeron, which is well-known from the …

Energy Flow in Particle Collisions
… the energy distribution produced by particle collisions. First, I establish a metric space for collision events by comparing their energy flows. I unify many ideas spanning multiple decades, such as observables and jets, as simple geometric objects in this new space. Second, I develop a basis …

Compiler Optimization Effects on Register Collisions
… number of values in use at one time (register collisions). Register collision is affected by compiler optimizations that take place before register allocation. Though the main purpose of compiler optimizations is to make the overall code better and faster, some optimizations can actually …

Classical models of heavy ion collisions
… of state (EOS) on intermediate energy heavy-ion collisions using classical microscopic models. The role of the EOS on the disassembly of expanding, hot nuclear matter, as well as the experimental data on multi-fragmentation and collective flow phenomena, are reviewed. Microscopic models used to …

Physically accurate collisions in StarLogo Nova
… elastic, inelastic, or partially inelastic collisions. However, StarLogo's current collision detection system relies on detecting overlapping objects after they have already collided, so it cannot simulate such collisions. We create a new continuous-time collision detection algorithm which …

Finite Element Analysis of Ship Collisions
The serious consequence of ship collisions necessitates the development of regulations and requirements for the subdivision and structural design of ships so that damage and environmental pollution is reduced, and safety is improved. A simplified collision model (SIMCOL) is currently being …

Injury Mechanisms in Roadside Motorcycle Collisions
… injury mechanisms in motorcycle-barrier collisions. Using this methodology, we investigated 9 serious motorcycle-to-barrier crashes. In these crashes, as well as in an analysis of 106 barrier crashes in Maryland, the thorax and lower extremities most commonly suffered serious injury. Of …

Electron Removal Processes in Proton-Methane Collisions
We have conducted a quantum-mechanical analysis within the independent elec- tron model to investigate electron removal processes in the proton-methane collision system in the 20 keV to a few MeV energy range. Similar to a previous work, we have used a spectral representation of the molecular …

Novel techniques for cold/ultracold molecular collisions
… introduced here offers a platform to study collisions at a regime where the scattering is mainly governed by quantum mechanics. Experimental developments of low energy collisions will challenge the theoretical description of molecular interactions, and aid in validating the accuracy of the …

Pion Production in Relativistic Heavy Ion Collisions
In der vorliegenden Arbeit wird die Pionenproduktion verschiedener Systeme (Ca+Ca, Ru+Ru, Zr+Zr und Au+Au) bei drei verschiedenen Strahlenergien (400, 1000 und 1500 AMeV) untersucht. Die Experimente wurden mit dem FOPI Detektor am Schwerionen Synchrotron (SIS) der Gesellschaft fuer …

Hadronization in Ultra-Relativistic Heavy Ion Collisions
… transition in both ultra-relativistic heavy-ion collisions and the very early universe. We develop very general criteria for hydrodynamical stability and apply them to a number of proposed solutions. We find that the hadronization is accomplished by deflagration solutions in both scenarios. We …
