Transfer functions have a crucial role in the understanding and visualization of 3D data. While research has scrutinized the possible uses of one and multi-dimensional transfer functions in the spatial domain, to our knowledge, no attempt has been done to explore transfer functions in the frequency domain. In this work we propose transfer functions for the purpose of frequency analysis and visu...
The ARC/INFO 6.1 Grid system was applied in the 170 km large Henley Dam and the 19.4 km large Cedara basins, KwaZulu Natal, South Africa, to determine hydrological and geomorphological parameters required to simulate water quantity and water. A sensitivity analysis was carried out to evaluate the effects of the grid mesh size on basin slope by producing a number of grids with grid mesh sizes ra...
JEL Classification J33, L85, M52. This study investigated the effects of salary structure, performance requirements, and type of business on the performance of housing agents. The participants in the study survey consisted of the employees of real estate firms in Kaohsiung, Taiwan. Restricted and unrestricted regression models were used to compare the goodness-of-fit of the regression models. A...

The unique nature of the molecular structures of gas hydrates results in curious acoustic properties which have yet to be adequately characterized. Understanding the acoustic behavior of hydrates in liquids, in bubbly liquids, and in sediments containing liquids and/or gas is vital for surveying their location using seismic or echosounding techniques and may become a key tool for monitoring hyd...
Multiple problems, including high computational cost, spurious local minima, and solutions with no geologic sense, have prevented widespread application of full waveform inversion (FWI), especially FWI of seismic reflections. These problems are fundamentally related to a large number of model parameters and to the absence of low frequencies in recorded seismograms. Instead of inverting for all ...
We present the analysis of 29.77 d of K2 space photometry of the well-detached massive 4.6 d O+B binary HD 165246 (V = 7.6) obtained during Campaign 9b. This analysis reveals intrinsic variability in the residual light curve after subtraction of the binary model, in the frequency range [0, 10] d−1. This makes HD 165246 only the second O+B eclipsing binary with asteroseismic potential. While som...
The observation of g-mode candidates by the SoHO mission opens the possibility of probing the internal structure of the solar radiative zone (RZ) and the solar core more directly than possible via the use of the p-mode helioseismology data. We study the effect of rotation and RZ magnetic fields on g-mode frequencies. Using a self-consistent static MHD magnetic field model we show that a 1% g-mo...
Observed p-mode frequencies have been extensively used to determine the the Sun's radial structure. The results of such inversions are often called \seismic models" of the Sun. In this work we investigate whether one can in fact construct models that match the measured solar frequencies to within observational errors. We invert linearized equations, relating frequency diierences between the Sun...
