Photograph of Bentwood Park and its surrounding area located in Dallas, Texas. The park, which contains a playground, basketball court, pond, and tennis courts, sits in the center of the picture along Bentwood Trail. It is surrounded by residential suburbs, and a church with a pond and parking lot is visible to its bottom left.

Photograph of Bent Tree Meadow Park and its surrounding area located in Dallas, Texas. The park is located near the center of the picture above Mitchell Elementary School and is outlined by Creekmeadow Drive and Voss Road on its upper and left sides respectively. The park and school are surrounded by residential suburbs.

Photograph of Campbell Green Park and its surrounding area in Dallas, Texas. The park, which sits in the center of the picture, is located beneath Campbell Road, to the right of Meadowcreek Drive, and to the left of Hillcrest Road. Residential suburbs surround the park, except for a business that is located near the upper right portion of the park.

A model-based flotation control scheme is being implemented to achieve optimal performance in the handling and treatment of fine coal. The control scheme monitors flotation performance through on- line analysis of ash content. Then, based on the economic and metallurgical performance of the circuit, variables such as reagent dosage, pulp density and pulp level are adjusted using model-base control algorithms to compensate for feed variations and other process disturbances. Recent developments in sensor technology are being applied for on-line determination of slurry ash content. During the fifth quarter of this project, all work was on hold pending the final novation of the contract to Virginia Polytechnic Institute and State University.

Recent developments in sensor technology are being applied for on-line determination of slurry ash content. During the fourth quarter of this project, a final attempt was made to calibrate a video-based ash analyzer for use in this application. It was concluded that the low ash content and the coarse particle size of the flotation tailings slurry at the Maple Meadow plant site made the video-based system unsuitable for this application. Plans are now underway to lease a nuclear-based analyzer as the primary sensor for this project.

A weekly publication, the Texas Register serves as the journal of state agency rulemaking for Texas. Information published in the Texas Register includes proposed, adopted, withdrawn and emergency rule actions, notices of state agency review of agency rules, governor's appointments, attorney general opinions, and miscellaneous documents such as requests for proposals. After adoption, these rulemaking actions are codified into the Texas Administrative Code.

Daily newspaper from Altus, Oklahoma that includes local, state, and national news along with advertising.
