An embedded controller for quad-rotor flying robots running distributed algorithms
Multiple collaborating quad-rotor flying robots are useful in a broad range of applications, from surveillance with onboard cameras to reconfiguration of wireless networks. For these applications, it is often advantageous to have the robot team be a distributed system. In this thesis, an embedded …

Interaction of an upper-tropospheric jet with a squall line originating along a cold frontal boundary
… surface cold frontal boundary was sampled during the Bow Echo and Mesoscale Convective Vortex Experiment. The Naval Research Laboratory P-3 aircraft and the National Oceanic and Atmospheric Administration P-3 aircraft simultaneously sampled the leading and trailing edge of this squall line, …

Investigation of Quad Bike Rollovers in the Workplace Farm Environment
Around 70% of workplace quad bike crashes have involved the quad bike rolling over. Despite this, limited information is known about the circumstances of quad bike crashes, specifically how rollover crashes occur in the workplace. It has been hypothesised that quad bikes ridden by a rider who is …

STUDYING THE PERFORMANCE OF A QUAD-GENERATION SYSTEM WITH STORAGE FOR IMPROVED ENERGY EFFICIENCY
With the increasing concern of global warming and energy shortage worldwide, multigeneration systems incorporated with environmental-friendly technologies are consistently attracting sustained attention as alternatives to the conventional energy supply methods. This is because these systems utilize …

Organizing for Social Policy Change: Child Care Policy Advocacy in Canada
Taking up the campaigns for a federal child care program as an example of social movement advocacy for policy change, this thesis examines how social actors have understood the need for better federal social policy related to child care in Canada. I develop a policy and advocacy history to preface …

Control of a fast steering mirror for laser-based satellite communication
… laser communication signals in space from Mars. The two main components of the pointing system on the spacecraft include an inertial reference frame to provide coarse laser control and a Fast Steering Mirror to remove any spacecraft jitter from the optical path. The optical path in the satellite …

Performance Analysis of a Binary-Tree-Based Algorithm for Computing Spatial Distance Histograms
The environment is made up of composition of small particles. Hence, particle simulation is an important tool in many scientific and engineering research fields to simulate the real life processes of the environment. Because of the enormous amount of data in such simulations, data management, …

An optimized dual-polarized quad-ridges horn antenna with pyramidal sidewalls
It is well known that quad-ridged horn antennas in general have impedance and radiation characteristics that are significantly worse than that of their double-ridged counterparts. Normally a voltage standing wave ratio (VSWR) of 3 over the operational bandwidth is used for the design specification …

The Beam Dynamics And Beam Related Uncertainties In Fermilab Muon G-2 Experiment
The anomaly of the muon magnetic moment, aμ ≡ (g-2)/2, has played an important role in constraining physics beyond the Standard Model for many years. Currently, the Standard Model prediction for aμ is accurate to 0.42 parts per million (ppm). The most recent muon g-2 experiment was done at …

The Effects of Maxillary Quad-Helix Appliance Expansion on Cephalometric Measurements in Growing Orthodontic Patients
<p>This study was conducted to examine the effects of maxillary quad-helix expansion on frontal and lateral cephalometric measurements in growing orthodontic patients. Twenty subjects, nine girls and eleven boys (x age = 10 years, 3 months), each exhibiting at least a unilateral posterior lingual …

Excellent Managers: Exploring the Acquisition, Measurement, and Impact of Leader Skills in an Australian Business Context
This thesis explores the acquisition, measurement, and impact of leader skills in relation to business managers' performance in an Australian context. The central problem explored in this thesis is whether effective managers are the same as successful managers, and the role of leader skills in that …

A Unified Spatial Data Structure for GIS
Most GIS systems use separate thematic "layers" to store different types of spatial data. Each of them contains specific characteristics of the area, so there are separate layers for the distribution of buildings, the road network or the relief of the terrain. The spatial information used in GIS …

Poking the Dragon: Australia-China Relations and a Truculent Fear of the Racialized 'Other'
Despite the strength and complementarity of economic ties between Australia and China, the contemporary relationship is paroxysmal at best and is marked from an Australian perspective by an increasing and pervasive level of suspicion and antithesization towards its largest trading partner. …
