Axisymmetric equilibrium and stability analysis in Alcator C-Mod, including effects of current profile, measurement noise and power supply saturation
The vertical position of elongated tokamak plasmas is unstable on the time scale of the eddy currents in the axisymmetric conducting structures. In the absence of feedback control, the plasma would drift vertically and quench on the wall, a situation known as Vertical Displacement Event (VDE), with …

Resistance to Flow Through Riprian Wetlands
… in this research has been placed on velocity profile measurement of flow within vegetation. Measurements were taken within various density configuration of rigid simulated vegetation for emergent and submerged cases. In addition, many of the experiments tested the effect on the velocity …

Profilometry with volume holographic imaging
High resolution, non-contact object profile measurement (profilometry) at long working distance is important in a number of application areas, such as precise parts manufacturing, optical element grounding and polishing, adversary target identification in military, terrace profiling, etc. The …

Validation of hygrothermal material modelling under consideration of the hysteresis of moisture storage
… parameters which are obtained from basic measurements, and the storage and transport coefficients which are defined within the balance and flow equations. It is the aim of the present study to develop a flexible and widely applicable material model which is not restricted to the current …

Performance Measurement Using IRI and Collision Rates in the Province of Alberta
… Internationally. It is calculated from direct profile measurement of the pavement wheel paths and translated into metres per kilometre. In 1999, the Province of Alberta tied its performance publicly to a rolling three year target IRI that was tabled on the floor of the legislature. Subsequent …

A three dimensional surface measurement and reconstruction system for respiratory function analysis
… not well suited in application for spirometric measurement for ambulatory monitoring. A sensor matrix measurement technique is investigated to identify suitable sensing elements with which to base an upper body surface measurement device that monitors respiration. This thesis is divided into two …

A study of water wave reflection using close range photogrammetry
… that is used to measure the water surface profile, as it produces an accurate and comprehensive analysis of the water surface profiles. Conventional photogrammetry techniques (photography) were used in preference to near real time photogrammetry (digital). Although near real time …

Electro-Optic Diagnostic Techniques For The CLIC Linear Collider
… the most promising devices to provide accurate measurement of the longitudinal bunch profile at the tens of femtosecond level is based on electro-optic techniques. In this thesis, a bunch profile monitor, based on electro-optic spectral decoding (EOSD), is currently developed for the CLIC Test …

Road Surface Measurement and Multi-Scale Modeling of Rubber Road Contact and Adhesion
… and contact mechanics theories and uses road profile measurements and data measured on various tire compounds. To be able to predict road surface characteristics, it is proven that road surfaces are of fractal nature on given ranges of scale. It is shown that while global fractal quantities …

Analytical Modeling for Sliding Friction of Rubber-Road Contact
Rubber friction is an important aspect to tire engineers, material developers and pavement engineers because of its importance in the estimation of forces generated at the contact, which further helps in optimizing tire and vehicle performances, and to estimate tire wear. It mainly depends on the …

Identification and Characterization of Damaging Road Events
… the United States, alone [1]. In addition, while measurements of these surfaces could be collected it would be impractical for two reasons, the first is the financial and extreme time burden this would take. Second, when collecting measurements of a road surface only the current state of a road …

Numerical Prediction of Drag Reduction and Interfacial Shapes Over Superhydrophobic Surfaces
… generated from a three-dimensional surface profile measurement. The air-water interface, which is assumed to be flat, is simulated using the volume-of-fluid (VOF) approach. The two flow regimes are studied for varying interface height $h$ to understand its effect on slip and drag reduction …
