3-D object reconstruction emission and transmission tomography with limited angular input

Description: The effects of the angular range of data taking in reconstructions in planar positron cameras using the deconvolution method and the matrix method, respectively, are investigated. It is found that in the absence of any a priori information there are undetermined components in the reconstruction if the field of view of the positron camera is limited. However, most of the undetermined components are recovered in the case in which the transverse spacing of the object is discrete, and all of them a… more

Acoustic location of infiltration openings in buildings. Final report

Description: Unnecessary air infiltration (''draftiness'') in buildings can be a major cause for excessive energy consumption. A method for using sound to locate, for subsequent sealing, the openings of air infiltration leakage paths in buildings has been investigated. The results of pertinent analytical studies, laboratory experiments, and field applications of this acoustic-location method are reported; and a plan is provided to encourage national implementation of the method. Low-cost, readily available … more

AES study of the adsorption of O/sub 2/, CO, CO/sub 2/, and H/sub 2/O on indium

Description: The adsorption of various oxygen-containing gases on clean polycrystalline In has been studied. For the In-O/sub 2/ system, the relationship between N(E) areas and dN(E)/dE peak heights for the In MNN Auger transition was found to be linear. At saturation, an oxygen/indium ratio of 3/2 was measured, consistent with the formation of the stable oxide In/sub 2/O/sub 3/. Low coverage sticking coefficients were found to be approximately .014 for O/sub 2/, approximately .004 for H/sub 2/O, approximat… more

Application of fault tree analysis to ignition of fire

Description: The potential impact of fire can be characterized by (I) the probability of ignition, (II) the probability distribution of fire growth as a function of time, and (III) the conditional probability distribution of losses given that a fire has broken out. The original ignition of unwanted fires has four principal causes of ignition: loss of control of wanted fire, arson, spontaneous combustion, and malfunction of equipment. Loss of control refers to ignitions which start with a planned or wanted i… more
