A Self-Potential for Monitoring Self-Sustaining Treatment for Active Remediation (STAR)
Self-sustaining Treatment for Active Remediation (STAR) is a novel soil remediation approach for Non-Aqueous Phase liquids (NAPLs) embedded in a porous medium. STAR is based on liquid smoldering combustion which destroys NAPLs while simultaneously generating heat due to the exothermic oxidation …

Optical Propagation of Self-sustaining Wavefronts and Nonlinear Dynamics in Parabolic Multimode Fibers
The aim of this thesis is to introduce my work which has generally been focused on optical wavefronts that have the unusual property of resisting commonplace phenomena such as diffraction and dispersion. Interestingly, these special beams are found both in linear and nonlinear situations. For …

Self-Sustaining Formation of Packets of Hairpin Vortices in a Turbulent Wall Layer
To observe the evolution of vortices, we developed a new vortex identification method and a visualization software. It is observed that the orientation of vortices aligns with the local real eigenvector of the velocity gradient tensor field over almost the entire region occupied by the vortex. By …

A Self-Sustaining, Boundary-Layer-Adapted System for Terrain Exploration and Environmental Sampling
… station to recharge the gliders. This system is self-sustaining, extracting energy from the planetary boundary layer. A nine degree of freedom vehicle dynamic model has been developed for the buoyancydriven glider. This model was used to illustrate anecdotal evidence of the stability and …

The Self-Sustaining Processes in a Hollow Cathode to Produce a Steady Electron Emission
… the electron emission of the cathode reaches a self-sustaining mode, ion bombardment of the low work-function materials. This research proposes the theory that the self-sustaining mode is a complex result of a mix of ionization states (singly, doubly, ...), the thermodynamic state, the electron …

A case study : creating momentum and self-sustaining change in product development through continuous improvement efforts
Traditionally, in Raytheon's Integrated Defense System Product Development Engineering Group, lean initiatives have not been fully adopted. Though the lean tools are useful, the engineering group is looking for more effective deployment methods to implement lean. The conventional push approach is …

Development of pulsed power sources using self-sustaining nonlinear transmission lines and high-voltage solid-state switches
… (LDMOS) devices to produce self-sustaining oscillations from a single input pulse. To date, this research work is one-of-a-kind in the field of NLTLs used for generating medium-power RF signals. Multiple NLTLs have been fabricated to identify the best available candidate …

Managing the transition toward self-sustaining alternative fuel vehicle markets : policy analysis using a dynamic behavioral spatial model
Designing public policy or industry strategy to bolster the transition to alternative fuel vehicles (AFVs) is a formidable challenge as demonstrated by historical failed attempts. The transition to new fuels occurs within a dynamically complex system with many distributed actors, long time delays, …

Establishment of woody savannah species on various mined substrates: Toward rehabilitating self sustaining plant communities at Navachab Gold mine
… for using mined substrates to establish self-sustaining, indigenous plant communities and to the development of mine closure and rehabilitation plans. To accomplish this goal, three studies as summarized below were carried out in the form of this MSc. The first study determined the plant …

The role of Marine Renewable Energy structures and biofouling communities in promoting self-sustaining populations of Non-Native Species
… their suitability for the establishment of self-sustaining populations, and therefore their dispersal potential for NNS. These findings inform design criteria and management options to minimise the biosecurity risk that these structures will pose as the industry expands.

Righting and Re-Writing The Blueprint: The creation of an Afrofuturistic television series and a self-sustaining television network to disrupt the misrepresentation of the Caribbean Family in British Television Drama
… producers, this thesis concludes that a self-sustaining, vertically integrated television network, not reliant on mainstream technology, money, or resources, would provide the autonomy required to give the British Caribbean and the Black Diaspora the freedom of expression to correct …

Essays on transition challenges for alternative propulsion vehicles and transportation systems
Technology transitions require the formation of a self-sustaining market through alignment of consumers' interests, producers' capabilities, infrastructure development, and regulations. In this research I develop a broad behavioral dynamic model of the prospective transition to alternative fuel …

In vitro studies of the role of cyclic-AMP in the mammalian circadian clock in the suprachiasmatic nuclei
… into 24 hr rhythms that are produced by self-sustaining clocks located within the organisms. In mammals the primary circadian clock is located in the suprachiasmatic nuclei (SCN) of the brain. My research investigated the biochemical mechanisms underlying this clock, focusing in …

A population dynamic model assessing options for managing eastern oysters (Crassostrea virginica) and triploid Suminoe oysters (Crassostrea ariakensis) in Chesapeake Bay
… the possibility Suminoe oyster might establish self-sustaining populations. To assess the risk of Suminoe oyster populations becoming established in Chesapeake Bay, a demographic population model was developed. Inputs modeled included: salinity, stocking density, reversion rate, reproductive …

Being in the right place at the right time : time of day discrimination by pigeons, Columba Livia
… a circadian type of timing mechanism, with a self-sustaining oscillator, mediates time-place learning over a period of 24 hr. Further support for this notion was found in Experiment 5 in which subjects were tested in constant dim light. In that experiment subjects' continued correct responding …

Copy-and-Paste
Copy-and-Paste is a self-sustaining system generating sameness in different locations. The same urban grid, the same outfit, the same house, the same car appear everywhere; copies of each other pasted all around. Copy-and-Paste is there, unquestioned, and seem-to-be arbitrary. This thesis explores …

The success and failure of United Nations multifunctional peace operations : a comparative case study of conflict transformation in Mozambique and Rwanda
… a study that examines the process of creating a self-sustaining peace (positive peace), and not only examining how to reduce the risk of resumption of violent conflict (negative peace). Herein, the study favours the concept Conflict Transformation as an extension of the term Conflict Resolution.
