Fluorinated esters of polycarboxylic acids
Fluorine containing esters of polycarboxylic acids are discussed. The use of these esters as extreme temperature lubricants and base fluids for greases is investigated
Development of lubricating oils suitable for use with liquid oxidizers Quarterly progress report, 1 Jun. - 31 Aug. 1970
Investigating ester and alkyl compounds as lubricating oils for use with liquid oxidizer
Inversion positivity and the sharp Hardy-Littlewood-Sobolev inequality
We give a new proof of certain cases of the sharp HLS inequality. Instead of
symmetric decreasing rearrangement it uses the reflection positivity of
inversions in spheres. In doing this we extend a characterization of the
minimizing functions due to Li and Zhu.Comment: 15 pages; references added and minor change
Separation of gas from liquid in a two-phase flow system
Separation system causes jets which leave two-phase nozzles to impinge on each other, so that liquid from jets tends to coalesce in center of combined jet streams while gas phase is forced to outer periphery. Thus, because liquid coalescence is achieved without resort to separation with solid surfaces, cycle efficiency is improved
Norms of quantum Gaussian multi-mode channels
We compute the norm of a general Gaussian
gauge-covariant multi-mode channel for any , where is a Schatten space. As a consequence, we verify the Gaussian optimizer
conjecture and the multiplicativity conjecture in these cases.Comment: 9 pages; minor changes; to appear in J. Math. Phy
Applications of a laser velocimeter in the Langley 4- by 7-meter tunnel
Applications of a laser velocimeter in the Langley 4 by 7 meter wind tunnel are discussed. The system configuration is described. The data acquisition, the laser velocimeter traversing, and the particle generating systems are discussed. Flow distribution and rotor wake applications are discussed
