Urbanization process converts natural landscape into an anthropogenic urban landscape. The present paper attempts to understand spatiotemporal urban dynamics of a mid-sized Indian town—Khammam in ...Telangana—by carrying out Land Use Land Cover Change Analysis for assessing urban growth pattern. A set of metrics of Landscape Analysis available to analyze growth pattern and broadly categorized into two sets—composition and configuration. Principal Component Analysis was used to identify three critical metrics from Landscape Analysis, viz., Number of Patches and Edge Length and Splitting Indexes while two additional metrics of the composition set, viz., Shannon Diversity and Shannon Evenness Indexes, based on expert opinion were added to make the study amenable. Twenty-three indicators of City Biodiversity Index broadly grouped into three core components, viz., Native Biodiversity in City, Ecosystem Services provided, and governance and management of CBI, were analyzed, and five indicators that were amenable to digital interpretation of satellite data pertaining to proportion of park and natural area within city, availability of water or quantum of water for urbanization, extent of natural protected area, extent of parks and natural area, and impact of vegetated area on ambient cooling were studied. Study indicated that in Khammam score of 8 out of a total score of 20 in CBI analysis indicated unsustainable growths, although trends among individual LULC components varied making it essential to study individual patterns. Study highlights need to use such indicators to guide urban development in mid-sized urban towns and cities that could substitute for large metropolitan cities as the growth engine in future.

The present study aims at determining the geographical location, spatial extent and geometric patterns of the archaeological structures and to examine the possible potential sites using the Indian ...Remote Sensing Satellite data. The study has been carried out over an area of 16 sq. km in and around Nalanda, including the 1.5 sq. km area of the present excavated site. The datasets used for the study include high resolution CARTOSAT-1 PAN (Aft) data at 2.5 m resolution of February 2006 and IRS P6 LISS-IV (MX) data at 5.8 m resolution of November 2005. Further, the study has been substantiated using ASI maps (ground-surveyed), topomaps and by limited field-work.
Urbanization has significant effects on local weather and climate and among these effects one of the most familiar is the urban heat island, for which the temperatures of the central urban locations ...are several degrees higher than those of nearby rural areas of similar elevation. Satellite data provides important inputs for estimating regional surface albedo and evapotranspiration required in the studies related to surface energy balance. Present study describes the analysis of day and night ENVISAT-AATSR satellite data for Urban heat island and surface thermal inertia. Field campaigns have been conducted in synchronous with the satellite data over pass for validating the surface temperature estimated from AATSR data. Satellite derived surface temperature values are within ±1° C from ground measured values. Heat island formations in urban regions of Hyderabad and environs can be clearly seen in the night time data with core urban regions showing high temperatures. Apparent thermal inertia derived from AATSR day and night data sets have shown typical variations over urban regions.
In this paper, a novel method of improving neural activity of human brain using sanathan Vedic chanting. The controversial effects of music on brain activity have sparked particular interest in the ...link between music perceptions and brain waves.Music can be a restorative trigger and have antidepressant properties, but it can also have proconvulsant properties, such as inducing epileptic seizures.However, there are various varieties of regular music-happy, calming, sad, and liking-and the neuro activity varies depending on the individual, their age, and the context. In this research, Sanathan Vedic Chanting (SVC) is offered as a regular music therapy for this problem, and its effects on several age groups are investigated. Rudram is interpreted as vedic chanting, and in a MATLAB environment, spectrum analysis is performed using the appropriate EEG patterns that were obtained from the laboratory were analyzed and observed the impact of vedic chanting signal energy. The effects of Sanathan Vedic chanting on human brain activity have been demonstrated by the results.
