Unbound linear operators in operator ranges
… of such results by considering operator ranges (the image of a bounded operator defined everywhere on a Banach space) as well as investigating and characterizing some of the properties of operator ranges. For the sake of generality we will for the most part be considering unbounded or …

Exploring Cyber Ranges in Cybersecurity Education
… and training to assist this need. Cyber ranges are a more recent development to provide hands-on skill training. These ranges, often virtual, provide a safe and accessible environment to improve practical skills and experience through hands-on application. They provide a training …

THE VEHICLE ROUTING PROBLEM WITH DEMAND RANGES
… called the Vehicle Routing Problem with Demand Ranges (VRPDR). With increasing competition, corporations are looking to minimize costs. This problem aims to reduce the cost of distributing goods by allowing flexibility in the delivered or dropped off quantity. This benefits the customer as well, …

Evolution of topography in glaciated mountain ranges
This thesis examines the response of alpine landscapes to the onset of glaciation. The basic approach is to compare fluvial and glacial landscapes, since it is the change from the former to the latter that accompanies climatic cooling. This allows a detailed evaluation of hypotheses relating …

The kinematics and dynamics of active mountain ranges
… is observed most clearly in high-elevation ranges like the Himalayas. By considering the force balance in these deformation belts, I suggest that, in most mountain ranges, the underthrusting foreland must act as a rigid base to the overlying range front, allowing it to act like a gravity …

Mortality of native forest vegetation in the Kaimai ranges
… mortality has been evident in the Kaimai Ranges, North Island, New Zealand for at least 40 years and affects a wide range of species and forest types. The mortality occurs above 550 m altitude and on each prominence has a lower limit which corresponds closely with the predominant cloud …

Higher Rank Numerical Ranges for Certain Non-Normal Matrices
… undertakes the study of higher rank numerical ranges for certain non-normal matrices, namely direct sums of Jordan blocks, and direct sums of the form (Jordan Block plus scalar multiple of the identity). The higher rank numerical range of a normal matrix is well-understood, but little is known …

Dissolution, Transport, and Fate of Lead on Shooting Ranges
Shooting ranges concentrate significant quantities of heavy metals, especially lead as spent shot and bullets, on very small parcels of land. Samples taken from a shooting range near Blacksburg, VA, USA provide information about the reservoirs and pathways of lead at shooting ranges in an upland …

Close Range: a Study of Battlefield Ranges At Shiloh and Antietam
A study of the range of fire at the battles of Shiloh and Antietam is based on an analysis of data found in the after-action reports printed in The War of the Rebellion: A Compilation of the Official Records of the Union and Confederate Armies. The data collected was any linear measurement, such as …

Wintering white-throated sparrows (Zonotrichia albicollis): home ranges, aggression and corticosterone
… studied, few studies have described winter home ranges. I tagged white-throated sparrows (n = 12) in Madison County, Kentucky, with 0.9-g radio transmitters during the winter of 2010-2011. Locations were entered into ArcGIS and home range sizes were estimated with 50% and 95% kernel analysis for …

Early Life History Stage Dynamics Across the Elevational Ranges of Andean Trees
… option species have is to shift their geographic ranges to respond to changing temperatures, precipitation, and other climatic variables. Accurately predicting how species distributions may shift with climate change requires an understanding of what controls species ranges that extends beyond …

Ranges of consideration: crossing the fields of ecology, philosophy and science studies.
Environmental issues are often complex with many different constituents operating according to a broad range of communication techniques. In order to foster negotiations, different perspectives need to be articulated in lucid ways sensitive to various viewpoints and circumstances. In my thesis I …
