stem cell factor (scf) is a critical protein with key roles in the cell such as hematopoiesis, gametogenesis and melanogenesis. in the present study a comparative analysis on nucleotide sequences of scf was performed in humanoids using bioinformatics tools including ncbi-blast, mega6, and jbrowse. our analysis of nucleotide sequences to find closely evolved organisms with high similarity by ncb...

This article provides a survey on modern methods of regional gravity field modeling on the sphere. Starting with the classical theory of spherical harmonics,weoutline the transition towards space-localizing methods such as spherical splines and wavelets. Special emphasis is given to the relations among these methods, which all involve radial base functions. Moreover, we provide extensive applic...

Abs tract . After a brief description of the modern instrumentation used in Geodesy for the detection, of the deformations of the crust of the Earth, follow a list of problems and a discussion concerning the needs for the survey of -the physical quantities of in_ terest in geodesy, geology, geophysics and engineering such as the strain invariants, the optimal network of baselines and the ac_ cu...

this work aims to extract the mineralogical constituents of the lahroud hyperion scene situated in the nw of iran. like the other push-broom sensors, hyperion images suffer from spectral distortions, namely the smile effect. the corresponding spectral curvature is defined as an across-track wavelength shift from the nominal central wavelength, and alters the pixel spectra. the common “column me...

The emerging new satellite technologies enabling earth observation at a spatial resolution of 0.6m or even 0.41m together with powerful and high speed computing and processing capabilities have brought revolutionary changes in the field of GIS-based cadastral land information system. The high-resolution satellite imagery (HRSI) is showing its usefulness for cadastral surveys due to which tradit...

From flat Earth, to round Earth, to a rough and oblate Earth, people's understanding of the shape of our planet and its landscapes has changed dramatically over the course of history. These advances in geodesy— the study of Earth's size, shape, orientation, and gravitational field, and the variations of these quantities over time—developed because of humans' curiosity about the Earth and becaus...

Image segmentation is an important task in image processing and computer vision which attract many researchers attention. There are a couple of information sets pixels in an image: statistical and structural information which refer to the feature value of pixel data and local correlation of pixel data, respectively. Markov random field (MRF) is a tool for modeling statistical and structural inf...

Vertical geodesy is undergoing a revolution because of two factors. First, new precise three-dimensional position measurement techniques used over very long distances and based on extraterrestrial reference systems provide a new class and precision of geometric data previously unavailable for geophysical investigations. Second, physical models in tectonic theory for large earthquakes predict cr...
