The three faces of international antitrust, and the paradox for international merger control
… the national rules, bilateral agreements, and multilateral initiatives that attempt to fill the vacuum created by the failure to agree upon international antitrust rules. The ‘stillborn’ International Trade Organisation (ITO) would have integrated international antitrust rules into the …

Evaluation of an adaptive control algorithm for use in uniform droplet spray in droplet based manufacturing
… algorithm was derived. Then, this algorithm and the existing integral control algorithm were coded for use in MATLAB simulations. The simulations were performed against each other over various sampling periods and noise classes to compare the performance of both droplet diameter mean and …

Artificial engineered materials for novel accelerator applications
… Resonators (CSRRs). These CSRRs act as a left handed medium at certain frequencies allowing the structure to be used for the generation of reverse Cherenkov radiation. The proposed initial design exhibits a left handed TM31-like mode at 5.5 GHz with a R/Q of 6.6 kΩ/m and a shunt impedance of …

An inventory and mapping of cliffs within the South Cumberland Plateau region of Tennessee
… of cliffs that permeate Tennessee’s South Cumberland Plateau (SCP) significantly influence the development, economy, and ecology of the region, yet little effort has been made to quantify these geophysical features. This study examined the use of LiDAR-derived digital elevation models (DEMs) to …

THE STUDY OF PERPENDICULARLY MAGNETIZED COFE/PD MULTILAYERS FOR DOMAIN WALL MOTION
… low saturation magnetization, narrow DW width and high spin polarization can induce low threshold current density for DW motion in CoFe/Pd superlattice-like multilayer films. Next, we show that DW motion can be driven by a low Jth with small bias field in the CoFe/Pd multilayers-based …

A Variation on a Theme of Vasconcelos
In 1967, Vasconcelos and Ferrand independently demonstrated that an ideal I in a Noetherian local ring R is generated by a regular sequence if and only if I/ I2 is free over R/I and pdRI < infinity. In this thesis, we prove that a radical ideal I in an excellent local normal domain is generated by …

Evaluation of a heated-air airship for the environment of Titan
… the atmosphere as well as the capability to land and study the surface at multiple locations. Several lighter-than-air gas airships and passive drifting heated-air balloon designs have been studied, but a heated-air airship could combine the best of both. A design tool was created to enable …

Continuous production of conducting polymer
… produce polypyrrole was designed, manufactured, and tested. Polypyrrole is a conducting polymer which has potential artificial muscle applications. The objective of continuous production was to produce both larger films and films with more consistent properties than the films produced by the …

Experimental and Theoretical Study of Inclusions During Initiation of Crevice Corrosion
… oxidation reaction were elemental sulfur and thiosulfate. Spectroelectrochemical cell experiments on MnS quantified the electrochemical production of thiosulfate. This finding linked the metallurgical and solution phases and suggested a depassivation mechanism based on a critical crevice …

Experimental investigation of multielement airfoils for large-scale wind turbines
… three-element system consisted of a main element and two flaps and a four-element system was tested with an additional strut. Experiments were performed with the ability to move two flaps to any location relative to a main element. Data were collected at a constant Reynolds number of 1.0 million. …

Ultrahigh-resolution, deep-penetration spectral-domain optical coherence tomography
… With a typical resolution of 10-15 [mu]m and a penetration of up to a few mm, OCT is widely used for medical diagnoses in fields such as ophthalmology and cardiology. However, the more common diagnostic tool in the microscopic regime of medical imaging is histology, an invasive technique …

Co-design Investigation and Optimization of an Oscillating-Surge Wave Energy Converter
… subsystems such as the geometry, power take-off, and controls is necessary. A codesign optimization in this paper seeks to include effects of all subsystems within one optimization loop in order to reach a fully optimal design for an oscillating-surge wave energy converter. A width and height …

Development of a Hollow-Core Fiberoptic Microneedle Device for the Treatment of Invasive Bladder Cancer
… for straight tubing with an inner bore of 150 ?m and a length greater than 50 mm long, Poiseuille's Law was shown to be accurate within 12% of experimental data for the pressure range of 69-517 kPa. Comparison between different needle design geometries indicated that tip diameters <55 ?m cause a …

Filtration behaviour of non-woven geotextiles in the gradient ration test
… soils, which have a D85 from 57 m to 1400 m and a silt content from 3% to 90%, with one geotextile. Gradient ratio values grater than one were observed, which imply the soil-geotextile composite permeability was less than that of the soil alone. This is attributed to some minor clogging of …

Heat and fluid flow analysis in a molten CuCl heat exchanger
… that transfer heat are; oxygen, hydrogen, and molten CuCl. The heat carried by oxygen and hydrogen can be recovered by the use of conventional heat exchangers. However, recovering heat from molten CuCl is very challenging due to the phase transformations that molten CuCl undergoes, as it …

The topology of GKM spaces and GKM fibrations
… p between an equivariantly formal T-manifold M and a GKM space fM. In particular we generalize the Chang-Skjelbred Theorem to this setting and derive some of its consequences. Then we consider the abstract setting of GKM graphs and define a category of objects which we refer to as GKM fiber …

Maskless photopatterning of cells in microfluidic devices/
Upon examining current methods for printing and patterning of live biological cells, there is a need for a method capable of printing with the resolution of single biological cells to organize them into complex structures. In order to fill this need, building upon previous design of a dynamic …

Global EDF Scheduling for Parallel Real-Time Tasks
… (DAG) where nodes represent computational work and edges represent dependences between nodes. In this model, we prove that GEDF provides a capacity augmentation bound of 4-2/m and a resource augmentation bound of 2-1/m. The capacity augmentation bound acts as a linear-time schedulability test …
