a method of mapping compact structure in radio sources using vlbi observations

a two-step procedure is developed for the determination of the angular structure of the compact components of radio sources from observations made with very-long-baseline interferometry (vlbi). the first step is to fit a model composed of circularly symmetric gaussian components to the observations. then this, or any other, model together..

the orientational correlation parameter for liquid cs/sub 2/, c/sub 6/h/sub 6/ and c/sub 6/f/sub 6/

the values of the second rank orientational correlation function g/sub 2/ and the effective polarizability anisotropy of liquids cs/sub 2/, c/sub 6/h/sub 6/ and c/sub 6/f/sub 6/ were determined by combining data from the rayleigh spectrum with cotton-mouton measurements on these liquids in a way which avoids difficulties with the interact..

writing an invention disclosure

several kinds of written invention disclosure are described and a checklist of their contents (e.g., date of conception, functional description, drawing) is developed. the patentability search disclosure is discussed in particular. in general, disclosures should provide a concise description of the invention, identifying its field of tech..

variance of the distributions of energy levels and of the transition arrays in atomic spectra

formulas are derived for the mean values and variances of the energy distributions of the levels of an atomic configuration and of the radiative transitions between the levels of two configurations (in intermediate coupling). the variance sigma/sup 2/ of the distribution of the eigenstate energies belonging to a given configuration is con..

transformerboard (power transformer insulation)

pressboard, well known in the textile and paper processing industries for more than a hundred years, was used for installation purposes in the first electric machines. it was not until the late 1920's, however, that designers became involved with the development of a pressboard type specially designed to meet the requirements of large pow..

pressure shifts and broadenings in the arc spectrum of krypton

the pressure shifts and broadenings of 25 lines of kr i in the visible and near infrared have been measured with krypton at pressures up to 13 torr and with helium at pressures up to 30 torr at a temperature of approximately 340k. the shifts that are due to krypton either are to lower wave numbers or are too small to be measured, whereas ..

a numerical investigation of several factors contributing to the observed variable intensity of deep convection over south florida

this study employs a revised version of the colorado state university three-dimensional numerical cloud scale model to investigate the observed behavior of deep convection over south florida on 17 july 1973. a brief description of recent model improvements is made. a combined balance and dynamics initialization procedure designed to intro..

a comparison of effective polarizabilities from electro-optical experiments using microscopic and macroscopic theories of the local electric field

previous theoretical results are summarized in which the microscopic fluctuation theory of ladanyi and keyes (1977) was extended to include the optical kerr effect (oke), cotton-mouton effect (cme) and light scattering (ls) intensities from liquids composed of asymmetric molecules. data from the literature for these experiments is compile..

optimize oxygen control in your boiler feed system

physical and chemical methods combine to minimize the effect of dissolved oxygen on preboiler components, but deaerators must be operated efficiently and scavengers should match system conditions closely

the orientational correlation parameter g/sub 2/ of symmetrical benzene derivatives

values for the orientational correlation parameter of liquid 1,3,5-trifluorobenzene and 1,3,5-trimethylbenzene at 295k are reported. the results were obtained by combining the cotton-mouton constants and the intensity of the reorientational contribution to the depolarized rayleigh scattering. the g/sub 2/ values are compared with the rati..
