For humans, walking is the principle means of locomotion,or moving from one point to another. While upright locomotionis a human characteristic, the way humans direct their locomotionhas not been studied extensively. Prior to the late 1940¹s,little research or scholarly thought was published regardinglocomotion. In 1950, J. J. Gibson published one of the firsttexts on visual perception, which included theories and researchon how humans interpret and react to a world of movement, even as...

Glue laminated wood deck systems are commonly used forbridge decks on girder bridge systems. These decks areusually covered with a hot-mix asphalt wearing surfacein conjunction with a bituminized fabric sheet waterproofingmembrane. Often cracks occur in the asphalt at theintersection of two adjacent deck panels which limits theuseful life of the wear surface, provides a poor ridingsurface and potentially allows moisture to flow to woodenbridge components.The purpose of this study was to investig...

The red imported fire ant, Solenopsis invicta, is an abundant and aggressive component of early-successional communities in the southeastern United States. After disturbance, it rapidly invades new habitats, and once there, it has strong competitive and predatory effects on the existing arthropod community. In upland coastal plain pine forests at the Savannah River Site in South Carolina, I conducted two studies of fire ant ecology. In my first study (chapter 1), I investigated the way in which ...

The biomass from a pilot-scale two-stage (carbon oxidation first stage, ammonia oxidation second stage) fixed-film biological aerated filter (BAF) was divided in three fractions depending on their attachment strength to the media: detached, easily detachable and strongly attached. VSS measurement showed that the detached and easily detachable fractions accounted for 25 to 40% of the biomass in the bed and are present even after backwash. Protein was the major constituent of all fractions of the ...

North Atlantic short-finned squid (Illex illececbrosus) is an underutilized species and calico scallops (Argopecten gibbys) do not achieved the same market value as Sea scallops due to their small size. North Atlantic short-finned squid have limited consumer acceptability due to their smaller, thinner, and more leathery texture than Atlantic long-finned squid (Loligo pealei). The market limitation of calico scallops is derived from their small size compared to other species of scallops available...

Analysis of strike data is critical to determine the true economic costs of bird strikes, determine the magnitude of safety issues, and develop preventive measures. Analysis of USAF bird-strike data identified trends and indicated suggested relationships among factors contributing to damaging strikes. From FY 1988 through FY 1997, the annual mean was 2,668 bird strikes with peaks evident in fall and spring. Daylight and dusk were hazardous for bird strikes. More bird strikes occurred during airf...

The problem of aircraft control allocation is that of finding a combination of control positions that cause the resulting aircraft moments to most closely satisfy a given desired moment vector. The problem is easily solved for the case of an aircraft having three control surfaces, each of which primarily imparts moments in each of the three aircraft axes. In this simple case, the solution to the control allocation problem is uniquely determined. However, many current and future aircraft designs ...

Assessing ecological risk to wildlife exposed to anthropogenic contamination in soil has traditionally been problematic. Attempts to standardize an approach to evaluate risk for various community types in North America have been challenging, given the variation in terrestrial communities and the values in which policy makers are bound to protect.

The reduction in thickness allows the wing swee...

The single-plate interferometer is a powerful flow visualization and aerodynamic measurement tool. It can provide full-field data for the density distribution in a non-intrusive manner, and it can be used for highly unsteady flows. While the device itself represents a large decrease in complexity over other forms of interferometry, the data reduction procedure has traditionally been laborious and difficult. To remove these difficulties and to improve the accuracy of the Virginia Tech interferome...
