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 are …

Factors related to creating force-velocity and load-velocity profiles with the squat jump
… Recently, it has become popular to use forcevelocity (FV) and load-velocity (LV) profiles created from progressively loaded squat jumps (SJs) to guide the resistance training process. By creating FV profiles, the coach can determine if the athlete has a force or velocity deficit and then …

Escape Velocity: A Narrative Short
… the development and production of Escape Velocity, a short narrative film. The writing, pre-production, shooting, and editing of the film are reviewed. Script drafts and a final budget are included in the appendices. The film concerns Larry Pipe and Percy Knuckle, best friends who dream of …

Constant Velocity Combustion Scramjet Analysis
The supersonic combustion ramjet or scramjet, is the most suitable engine cycle for sustained hypersonic flight in the atmosphere. The present work deals with the performance of a scramjet engine by parametrically analyzing the performance of the ideal scramjet using the engine parameters: specific …

A Novel Method to Assess Pulse Wave Velocity using Single Velocity Encoding in Phase Contrast Imaging
The measurement of pulse wave velocity (PWV) using conventional phase contrast magnetic resonance imaging (PC-MRI) is recognized as a standard technique to assess arterial stiffness by measuring the arrival times of blood velocity waveforms. Conventional PC-MRI requires the acquisition of two sets …

Velocity compensation in stepped frequency rada
… The solution to this problem is to apply velocity compensation to the received signal, which can eliminate the degradations due to Doppler effects. Three velocity compensation schemes for the detection of a moving target in clutter are designed, discussed, and compared in this thesis. …

Velocity profile in confined elliptic fractures
… fracture. In order to do so, the non-uniform velocity profile in an elliptic fracture with laminar flow of both Newtonian and non-Newtonian fluids was calculated. A transient flow computer program is presented using the method of characteristics, to show the frictional effects on acoustic …

The measurement of flow velocity distribution
… averaging times. Consequently, correlation and velocity profile measurements are made from an experimental flow rig. A waveform analysis program is used to analyse these measurements. The Fourier transform deconvolution is shown in this case to have poor noise immunity. For this reason, an …

Rapid learning in high velocity environments
… 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, 1981; Eisenhardt, 1989a). Semiconductor manufacturing and process development are chosen as settings for …

High-Velocity Impact of Metal Microparticles
… that control the upper and lower bounds of the velocity window over which cold spray can occur are explored. Microparticle impact behavior regimes are measured and mapped as a function of velocity for several different metals, and the role of surface passivation layers in controlling cold spray …

Velocity distribution in steep rough channel
… thesis consists of an experimental study of the velocity distribution in tranquil, stable tumbling and rapid flow regimes in a steep rectangular channel with artificial roughness elements. Four shapes of roughness elements, rectangular, parallelogram, triangular, and semi-circular, were used. …

The Quantized Velocity Finite Element Method
… of this framework has been coined the "quantized velocity finite element method" (QVFEM). The work performed herein lays the foundational development of what is hoped to become a new paradigm shift in computational fluid dynamics.

The discrete velocity method in plasma physics
… objective of this thesis is to apply a discrete velocity model to kinetic theory problems in plasma physics. Numerical approaches commonly used in kinetic theory are described and compared with the discrete velocity models. The discrete Boltzmann equation (DBE) is a commonly used discrete …

Velocity analysis in the presence of uncertainty
Velocity analysis resolves relatively long scales of earth structure, on the order of 1 km. Migration produces images with length scales (wavelengths) on the order of 10's of m. In between these two scale regimes lies another, corresponding roughly to structures between 60 to 300m in extent, in …
