High velocity impact fracture
… of ductile structural components under high velocity impact are investigated numerically and theoretically. Attention is focused on the formation and propagation of through-thickness cracks, which is difficult to experimentally track down using currently available instruments. Studied …

Rapid learning in high velocity environments
… investigates how rapid learning occurs in high technology industries, many of which operate in what Bourgeois and Eisenhardt (1988) term "high velocity environments." The dissertation consists of three empirical studies, which follow the method of extended case study research (e.g. Yin, …

High-Velocity Impact of Metal Microparticles
… This technique allows for precisely controlled high-throughput impact testing, creating new opportunities for the study of material behavior under extreme dynamic conditions. In this thesis, a series of experiments are presented which use the LIPIT to impact metal microparticles onto metal …

Control interface for a high velocity teleoperated robot
… suitable for controlling a microrover at high speed. For the purposes of this thesis, a control interface describes the collection of software and input devices used by an operator to interact with a microrover that is not within sight. A microrover is a small, lightweight, robotic …

Development of Superconducting Spoke Cavities for High-Velocity Applications
… in possible applications of spoke cavities for high-velocity applications. The first task is to explore the design parameter space for low-frequency, high-velocity, single- and double-spoke superconducting cavities in order to determine how each design parameter affects the electromagnetic …

Building Inventory Simulations for High Velocity Garment Retail Stores
… for a brick-and-mortar retail business with high sales velocity and product portfolio complexity, this project created a Monte Carlo tool that simulates how upstream shipment decisions impact capacity utilization and product complexity. The simulation model was built in two steps, first a …

Quantifying Plasticity and Temperature in High Velocity Microparticle Impacts
… ~10-1500 m/s. Through a combination of the high velocity and small length-scale of the impact, strain rates exceeding 10⁷ /s can be achieved while maintaining a subsonic plastic wave, preventing formation of strong shockwaves and hydrodynamic behavior. The LIPIT has been effectively applied …

Erosion-Corrosion of Cr3C2-NiCr High Velocity Thermal Spray Coatings
… of Cr3C2-NiCr thermal spray coatings under high temperature, high erodent velocity, turbine conditions. Erosion-corrosion is a generalised wear phenomenon where the combined effect of each degradation mechanism generates more extensive mass loss than the sum of each mechanism acting …

The effect of high-velocity, low-amplitude manipulation on suboccipital tenderness
High-velocity, low-amplitude (HVLA) manipulation is commonly advocated by manual therapists to relieve spinal pain and dysfunction. The aim of this controlled, single blinded study was to investigate whether HVLA manipulation of the occipito-atlantal (OA) joint had any lasting effect on pressure …

Design of experiment analysis of high velocity oxy-fuel coating of hydroxyapatite
Due to the flexibility and cost effectiveness the high velocity oxy-fuel (HVOF) thermal spray process has been widely adopted by many industries. Though there are different types of flame spraying processes, the HVOF thermal spray process utilises only powder as the coating material rather than …

Multi-dimensional simulations of bow shocks of massive, high-velocity runaway stars
… shocks from stars at the tail end of the runaway velocity distribution which we refer to as high-velocity runaway (HVR) stars. We use PLUTO, a magneto-hydrodynamics grid code, to simulate these bow shocks, performing hydrodynamic simulations in 2- and 3-dimensions, while including thermal …
