Research on Identifying Method of Freezing-Thawing Soil Hydraulic Properties
The identification of freezing-thawing soil hydraulic properties is the basis and key problem of studying soil water movement. Current identifying methods of the properties have many limitations, such as big error, high uncertainty and low operability. Thus, the identifying method of freezingthawing soil hydraulic properties was researched in the research. The estimating parameters of soil free...
متن کاملElectromagnetic Wave Propagation in Random Waveguides
Abstract. We study long range propagation of electromagnetic waves in random waveguides with rectangular cross-section and perfectly conducting boundaries. The waveguide is filled with an isotropic linear dielectric material, with randomly fluctuating electric permittivity. The fluctuations are weak, but they cause significant cumulative scattering over long distances of propagation of the wave...
متن کاملFreezing and thawing or freezing, thawing, and aging effects on beef tenderness.
The objective of this study was to determine the effect of freezing and thawing or freezing and thawing with an additional aging period after frozen storage on the tenderness of longissimus lumborum (LL) and semitendinosus (ST) steaks relative to aged, fresh steaks. Left-side LL and ST (n = 35 each) were obtained from U.S. Select carcasses classified at the grading stand by the U.S. Meat Animal...

متن کاملNonlinear pulse propagation in dispersion decreasing fibers
By numerically solving the nonlinear Schrodinger equation, we analyze pulse propagation through dispersion decreasing optical fibers (DDFs) in which the core radius varies along the length of the fiber; this in turn leads to a variation of dispersion as well as mode effective area along the length of the fiber. We calculate an optimum core radius profile required to create a local balance betwe...
