The need for an antimicrobial penetrant-sealer became evident as the problem of flaking paint in food processing plants was explored. Flaking paint can fall into product, a situation which cannot be tolerated. The standards, set by the packing industry, for purity, freshness, and attractiveness preclude any foreign matter in product. Flaking paint as a problem has been with us since paint was f...

The relationship between malathion droplet size (VMD) and degree of damage to 1990, 1K and 2K General Motors paint standards was investigated in the laboratory and field. Laboratory tests indicated a positive correlation between malathion droplet VMD and damage spot size. Laboratory settling chamber tests revealed that size-thresholds of droplets too small to cause visible damage averaged 8 and...

Output power of thermoelectric generators depends on device engineering minimizing heat loss as well as inherent material properties. However, the device engineering has been largely neglected due to the limited flat or angular shape of devices. Considering that the surface of most heat sources where these planar devices are attached is curved, a considerable amount of heat loss is inevitable. ...

Symmetry is a salient visual property: It is easy to detect and influences perceptual phenomena from segmentation to recognition. Yet researchers know little about its neural basis. Using recordings from single neurons in monkey IT cortex, we asked whether symmetry-being an emergent property-induces nonlinear interactions between object parts. Remarkably, we found no such deviation: Whole-objec...

We present the Video Paintbox; a novel system capable of transforming video into stylised animations. Our system solves the problem of temporally coherent painting for a wide class of video, and is able to introduce cartoon-like motion emphasis cues. Coherent painting in video is a long-standing problem that is associated with the difficulties in placing, orienting, and sizing paint strokes ove...

If possible, all surfaces painted with lead-based paint should be abated by replacement, encapsulation, or paint removal. Ordinary paint is never an appropriate encapsulant; it is only part of a temporary maintenance procedure. Encapsulation materials should be durable and, where possible, affixed with both fasteners and adhesive. Paintlike coatings should be used with caution. Only coatings an...

This paper presents several methods for shading meshes from scanned paint samples that represent dark to light transitions. Our techniques emphasize artistic control of brush stroke texture and color. We first demonstrate how the texture of the paint sample can be separated from its color gradient. We demonstrate three methods, two real-time and one off-line for producing rendered, shaded image...

We present high spatial-resolution mapping of soil lead (Pb) concentrations in a small-urban residential setting. X-ray fluorescence was used to measure soil Pb at170 properties in the City Park neighborhood of Appleton, Wisconsin. Greater than two-thirds of soil samples collected from drip lines contained more than 400 μg g of Pb, and one third exceeded 1200 μg g. Soils adjacent to homes built...

Current practice of paint condition assessment on civil structures typically involves labour-intensive and time-consuming visual inspections. This can be particularly costly for large and complex structures. In this study, hyperspectral imaging and classification techniques are proposed as a method to objectively assess the state of the paint on a civil or other structure. The ultimate objectiv...
