The ability to measure the thickness of paint on graphite/epoxy composite structures directly would be of benefit in the aerospace industry. The weight reduction would increase fuel mileage for the airline customer. An additional reason for reducing the thickness of paint on graphite/epoxy composites is not as obvious as the weight savings. A concern in the use of composite structures has been ...

Recent developments in computer graphics software and hardware have made it possible to write computer graphics programs that can be used to solve automotive paint engineering problems. New surface reflection models have been created for simulating the appearance of automotive paint, and the hardware available today on graphics cards allows these reflection models to be evaluated in real-time. ...

Physically based rendering of metallic and pearlescent appearance requires knowledge of the composition of paint or coating. However, sometimes composition is not available, while the Bi-directional Reflectance Distribution Function (BRDF) is measured from an actual sample. Such a situation invokes the inverse problem to find a paint composition from a given BRDF. We solve this problem based on...

This paper is about a development process of a novel sound effect device, which resembles ordinary spray can, with the purpose of adding sound elements to existing spray paint art. To this end, we first investigate the processes and the characteristics of spray paint art and find the common elements that can be expressed in an auditory form. We then design a prototype using Arduino and various ...

A THESIS ON TECHNIQUES FOR NON-PHOTOREALISTIC SHADING USING REAL PAINT by Reynold J. Bailey ADVISOR: Professor Cindy Grimm May, 2004 Saint Louis, Missouri The goal of this research is to explore techniques for shading 3D computer generated models using scanned images of actual paint samples. The techniques presented emphasize artistic control of brush stroke texture and color. We first demonstr...

A laboratory test with a flow-through system was designed and its applicability for testing antifouling paints of varying efficacies was investigated. Six different formulations of antifouling paints were prepared to have increasing contents (0 to 40 wt.%) of Cu2O, which is the most commonly used antifouling substance, and each formulation of paint was coated on just one surface of every test p...

When teacher salaries are discussed, two very different pictures often emerge. The first of these portrays teachers as underpaid, overworked servants of the public good. The second paints a picture of an overpaid group of civil servants who spend very little time actually working. As we might expect, reality is somewhere between these two extremes. This report looks at Michigan teacher salaries...

Could titanium-clean air be how advertisers one day try to sell us the virtues of paint or even clothing that reduces the pollution caused by automobiles? The technology behind such products involves the well-known ability of titanium dioxide (TiO2) to photocatalytically split water to form hydroxyl and peroxyl radicals, a reaction that has already been harnessed to make self-cleaning windows. ...

Environmentally Safe and Effective Processes for Paint Removal Paint stripping and repainting of aircraft surfaces arc requircd periodically during thc operating lifetime of an aircraft. Historically, paint removal has been achieved using chemical strippers, involving materials which contain toxic components and which create hazardous working conditions. The process generates large amounts of h...
