Snowfall signatures over ocean are analyzed using satellite and airborne microwave radiometer measurements at frequencies ranging from 37 to 340 GHz. Data used in the analysis include satellite data from the Advanced Microwave Scanning Radiometer – EOS and the Advanced Microwave Sounding Unit – B, and airborne data from a millimeter-wave radiometer and a dual-frequency precipitation radar durin...

Advanced Microwave Scanning Radiometer (AMSR) on a board of ADEOS-II satellite had 14 channels, two of which received outgoing Earth’s radiation at an absorption band of molecular oxygen at frequencies ν = 50.3 and 52.8 GHz with vertical (V) polarization. Numerical experiments with a microwave radiative transfer model were carried out at the variations of the atmospheric and ocean surface param...

The atmospheric circulation spans a wide range of spatial scales, including the planetary scale (∼10,000 km), synoptic scale (∼2,000 km), mesoscale (∼200 km), and convective scales (<20 km). The wide scale separation between convective motions, responsible for the vertical energy transport, and the planetary circulation, responsible for the meridional energy transport, has prevented explicit re...

in this paper, an integration of a symbolic power series method - padé approximation technique (ps - padé), was utilized to solve a system of nonlinear differential equations arising from the similarity solution of laminar thermal boundary layer over a flat plate subjected to a convective surface boundary condition. as both boundary conditions tended to infinity, the combination of series solut...

in the current investigation, fe3o4 water-based nanofluids were synthesized to examine the effect of an alternative 3-d external magnetic field on its thermal behavioral pattern. a solvothermal method was used to prepare the magnetite nanoparticles. to characterize the nanoparticles, the study employed transmission electron microscopy, x-ray diffraction, fourier transform infrared spectroscopy,...

leather manufacturing involves a crucial energy-intensive drying stage in the finishing process to remove its residual moisture. determining drying characteristics of leather is vitally important so as to optimize the drying stage. this paper describes an analytical way for determination of the drying characteristics of leather. the model presented, is based on fundamental heat and mass transfe...

In the initial phases of the Levitated Dipole Experiment (LDX), multiple frequency ECRH (with frequencies between 2.45 and 28 GHz) will be used to produce a population of energetic electrons at high-β. Use of multiple frequency ECRH in mirror experiments have shown a reduction in plasma turbulence and increased heating efficiency. The pressure profile will be controlled by adjusting the relativ...

In order to help the detection and identification of low-frequency p-and g-modes in the solar spectrum observed by ground-based networks and SoHO experiments, we study the properties of low degree (=0-6) low-frequency (100-2000 µHz) solar oscillations. The frequencies of p-and g-modes have been computed for a set of solar models with updated physics. We point out the specific properties of the ...

High frequency oscillatory ventilation takes advantage of unique principles of gas flow when respiratory frequencies exceed 3 Hz (180 breaths per minute). These gas flow principles enable the alveolar gas turnover at volumes below or equal to physiologic deadspace. One of these principles is call asymmetrical velocity profile. As Froese and Bryan described in their “State of the Art” article on...

A paradigm for Hall discharge modeling is presented whereby only the time scale of the lowest-frequency mode is explicitly resolved. The ability of such a low-frequency model to reproduce with excellent accuracy the breathing mode is demonstrated through comparisons with a fully time-dependent numerical model. Based on this formalism, an approximate linearized model is derived which essentially...
