The catalytic incineration of toluene over gamma-Al2O3-supported transition-metal oxide catalysts in the temperature range of 200-380 degrees C was investigated employing a fixed bed flow reactor. CuO/gamma-Al2O3 was found to be the most active of seven catalysts tested. Using this catalyst with different wt% Cu in the incineration of toluene, we found that(More)
A computational framework for recognizing an object of interest in a complex visual environment is described. Arising from the problem of finding the destination address block on a mail piece, a general framework for coordinating a collection of specialized image-analysis tools is described. The resulting system is capable of dealing with a wide range of(More)
An important task in postal automation technology is determining the position and orientation of the destination address block in the image of a mail piece such as a letter, magazine, or parcel. The corresponding subimage is then presented to a human operator or a machine reader (optical character reader) that can read the zip code and, if necessary, other(More)
4 framelvork for determining special interest objects in images is presented in the context of determining destination &dress blochs on images of mail pieces such as letters, magazines, and parcels. The images range from those having a high degree of global spatial structure (e.g., carefully prepared letter mail envelopes lvhich conform to specifications)(More)
The objective of an Address Block Location System is to determine the position and orientation of the destination address block in an image of a mail piece such as a letter, magazine, or parcel so that the corresponding sub-image can then be presented to either a human or machine reader (OCR) to direct the mail piece to the appropriate sort category. This(More)
A fixed bed reactor was used to assess the catalytic incineration of toluene by various transition-metal oxide species supported on gamma-Al(2)O(3). CuO/gamma-Al(2)O(3) was found to be the most active of seven catalysts investigated. The CuO species, with a Cu content of 5% (wt), was hence used with four different supports (CeO(2), gamma-Al(2)O(3), TiO(2)(More)
The effect of catalyst loading, oxygen pressure, reaction temperature and phenol concentration on phenol conversion and total organic carbon (TOC) conversion, using CeO(2) as the catalyst, was investigated. There appeared a maximum rate of phenol conversion and TOC conversion as the catalyst loading increased. With phenol concentrations in the range of(More)
The effect of promoter addition on activity of CeO(2)/gamma-Al(2)O(3) was assessed via the CWAO of phenol. Adding Cu as the promoter rendered the most effective performance, followed by Mn, although the performance of Mn-promoted catalyst was inferior to CeO(2)/gamma-Al(2)O(3). Mineralization of phenol was effectively implemented at 160 degrees C using(More)
The objective of an Address Block Location System (ABLS) is to determine the position and orientation of a destination address block in a mail piece image of either a letter, magazine, or parcel. The corresponding sub-image can then be presented to either a human or machine reader (OCR) to direct the mail piece to the appropriate sort category based on the(More)
