VOC-emission from indoor paint during and after application is determined by four different methods. VOC-emission data gathered by these methods are compared with calculations from a dynamic computer model describing the time-dependence of the VOC-emission in the room atmosphere. This comparison indicates that the ‘in-can-individual-VOC method’ combined with computer calculations yields results comparable with the ‘practical methods’. Moreover, the combination of ‘in-can-individual-VOC method’ with computer calculation allows variations in the size of the room, the application rate, VOC-content of the paint and the rate of air change, without the necessity of additional experiments and, therefore, offers an approach with a reduction is costs.

We performed an examination attestation to establish beginning balances for the audit of the Principal U.S. Army Corps of Engineers (USACE), Civil Works, Financial Statements for the Fiscal Years Ending September 30, 2004 and 2003. USACE reports General Property, Plant, and Equipment (PP&E) as an asset line item on the Civil Works Balance Sheet. For FY 2003, the net book value of PP&E was $30.9 billion. Buildings and other structures comprised $18.3 billion of the total PP&E. For FY 2004, the net book value of PP&E was $28.4 billion. Buildings and other structures comprised $16.1 billion of the total PP&E. The net book value represents the difference between the historical acquisition (book) cost and the associated accumulated depreciation of the assets. As of September 30, 2003, USACE had about 40,000 structures located at about 1,273 field sites in the continental United States, Alaska, and Hawaii.

This paper describes the crucial high power tests like multipaction-and band-edge tests performed on typical 16- and 18- channel output multiplexers. Analysis and measured results of the thermal behavior – especially under band-edge operation - as well as predicted and measured results of the multipaction test under consideration of multiple carrier operation are presented.

A hybrid mode-matching(MM)/finite element (FE) CAD method is applied for the fast CAD of ultra-wide stop band and high return loss waffle-iron filters. The design is based on cascaded waffe-iron sections with a different number of bosses in the cross-sections utilizing a new non-isotropic waffle-iron structure with individually optimized lengths. For the efficient optimization with regard to the S parameters, the generalized scattering matrix (GSM) combination technique is used with an automatic selection of localized and accessible modes. An overall block-LU-decomposition method allows one to calculate the field intensities within the waffle-iron sections. The optimization carried out by a robust direct search method achieved a waffle-iron filter with better than 30dB return loss between 7 and 8.3 GHz, and more than 70 dB rejection between 12 and 60 GHz. The theory is verified by excellent agreement with measurements.
