Hepatocyte growth factor (HGF) is associated with tumour progression and increases the invasiveness of prostate carcinoma cells. Cell migration and invasion requires reorganisation of the actin cytoskeleton; processes mediated by the Rho family GTPases. p21 activated kinase 4 (PAK4), an effector of the Rho family protein Cdc42, is activated downstream of(More)
Satellite images play a major role in the analysis of land cover, topographic analysis, geosciences etc. There has always existed a tradeoff between the image resolution and the image cost. In this paper, a modified discrete wavelet transform and interpolation based technique is proposed for enhancing the resolution of satellite images having low resolution(More)
SAR images have the capability to detect and identify various features of lands on the basis of scattering behavior of the targets. It is observed that various features like soil moisture, roughness, crop health and crop growth etc., can be easily detected with SAR, but detection of subsurface fire (hotspot) with SAR images has to be explored. Therefore, in(More)
Retrieval of sea surface height by performing altimetry on SARAL datasets over Ramganga reservoir is presented in this paper. Satellite altimetry for inland water bodies has evolved from investigation of water height retrieval to monitoring over a past few decades. The purpose of performing altimetry over inland water bodies is to estimate the water level(More)
The objective of this paper is to find the soil moisture of the vegetated land cover using data fusion approach between C-band SAR and optical data. For which we are using RADARSAT-2 and MODIS data and Dubois model were used to evaluate the soil moisture of vegetated land cover. The principle behind this fusion approach is that the backscattering(More)
As an important representative of climate change and main disruption to environments, subsurface fire (Hotspot) is coming extended scientists and the general public consideration. Satellite images play an important role to get quick and complete information about the occurrence and development of subsurface fire. In this paper, INSAT-3D data an Indian(More)
The aim of this paper is to explore the information obtain from the fully polarimetric SAR data. Fully polarimetric SAR data contain both magnitude and phase information therefore it contains great potential about target classification. By using both parameter amplitude and phase we can distinguishes different types of scattering mechanism. For fully(More)
One of the main application of Synthetic Aperture Radar (SAR) data is developing the monitoring system for various applications like land cover and land use dynamics, vegetation mapping, canopy characterization and natural hazards by discriminating the change areas between two different dates images. In this paper, KLT (Kanade-Lucas-Tomasi) tracker has been(More)
In recent years plasma-sprayed coatings and polymer coatings have found wide application in manufacturing. Although the quality of the coatings improved over the years, there is a need for reliable NDE techniques to assess the quality and test the integrity of these coatings. Most existing techniques are not suitable for real-time applications. The(More)
Harmonic analysis is used to map the periodic change variations, and it may provide the stability in the periodic changes about the specific changes at a particular time, which are occurring in Hot spot and non-hot spot regions. Constitutional sinusoidal term provides the amplitude and phase information, which are presented by the unique value. Amplitude(More)
