      Modeling results of sprite streamer formation from large ionospheric inhomogeneities or patches (several tens to hundreds of meter wide) indicate that positive streamers can be initiated at subbreakdown conditions from the ...
    • Formation of streamer discharges from an isolated ionization column at subbreakdown conditions

      This Letter reports a modeling study on the formation of streamer discharges from an isolated ionization column under subbreakdown condition. Numerical simulations show that positive streamers are able to form from the ...
    • FORMULATION OF THE ENERGY EQUATION IN FLUID DYNAMICS 

      Dubbelday, Pieter S. (1975)
      Formulations for the energy equation exist in variety in fundamental and applied texts and monographs on fluid dynamics. It is often difficult to establish the set of conditions leading to a given formulation. More deleterious ...
    • Four short-period algols 

      Rafert, James Bruce (1990-10)
      We have analyzed the light curves of four close binary star systems (BV 267, RU UMi, XZ CMi, and VV UMa) using the Wilson-Devinney differential corrections model. The present system geometries of these binaries is that of ...
    • Fragile binary candidates in the SDSS DR8 spectroscopic archive 

      Zhao, J.K; Oswalt, Terry D.; Zhao, G. (2012-02)
      We present a catalog of 80 very wide fragile binary candidates (projected separations >10,000 AU) from the Sloan Digital Sky Survey Data Release Eight spectral archive. The pairs were selected based on proper motion, radial ...

    • Free-space optical communication link using spatial optical encryption 

      Murshid, Syed H.; Howard, William B.; Chakravarty, Abhijit (2011-05-04)
      Free-space optical links are ideal for short-range (1 km to 3 km) communications. An innovative new technique called Spatial Optical Encryption can be used to secure laser data communications. With this technique, data can ...
    • FREQUENCY DISTRIBUTION PATTERNS AND PARTITIONING OF COPPER, IRON AND ZINC IN SELECTED TISSUES OF THE BLACK MULLET (MUGIL CEPHALUS) 

      Venuto, Charles J.; Trefry, John H. (1983)
      Copper, iron and zinc concentrations were determined for muscle, gill and liver tissue from 45 black mullet (Mugil cephalus) collected in Turkey Creek, an embayment of the Indian River Lagoon, Florida. In the liver, Fe ...
    • Frequency-selective surface coupled metal-oxide-metal diodes 

      Kinzel, Edward C.; Brown, Robert Laurent; Ginn, James Chris; Lail, Brian A.; Slovick, Brian A.; Boreman, Glenn D. (2013-06-11)
      Metal-Oxide-Metal diodes offer the possibility of directly rectifying infrared radiation. To be effective for sensing or energy harvesting they must be coupled to an antenna which produces intense fields at the diode. While ...
    • Function approximation using a sinc neural network 

      Elwasif, Wael R.; Fausett, Laurene V (1996-03-22)
      Neural networks for function approximation are the basis of many applications. Such networks often use a sigmoidal activation function (e.g. tanh) or a radial basis function (e.g. gaussian). Networks have also been developed ...
