Assessment Of Land Use And Land Cover Change In District Baramulla (J&K)
Abstract: The present study aims to study the land use land cover change detection in district Baramulla from 1980 to 2014. The images of two different time periods 1980 (MSS) and 2014 (OLI) have been used to measure the change detection in the study area. Spatial and radiometric enhancement has been carried out to improve the image quality. The analysis revealed that the area under built-up, horticulture and pasture has shown …

Effect of Solar X-ray Flares on VLF Radio Wave Signal Strength at 19.8 and 24 kHz Received at Khatav (India) (16°46'N, 75°53'E)
Abstract: The period from August 2009 to July 2012 was an important period as 2009–10 was solar minimum period, and solar cycle was extended by 16 months during this period. In this period, solar activity like solar X-ray flares, solar wind, coronal mass ejections were at minimum level. In this research, it is focused on detailed study of response of signal strength of VLF radio waves transmitted by VLF station NWC …

Morphological Dynamic of Ekakula Spit and Kalam Island in Kendrapara District of Odisha—A Geospatial Approach
Abstract: Odisha Coast of India is about 480 km long stretching and oriented in a SW-NE direction. The sediment contributions from the rivers are deposited along the coast. The littoral drift deposition builds spits and bars at the river mouths especially at the southern side of the river mouths. The one of the study area is situated between 20°40’57.417”N and 20°45’49.947”N latitude and 87°1’5.576” E and 87°7’4.959”E longitude. Another is the …

Modeling the Solar Radiation Parameter over Abuja using Neural Networks
Abstract: Many computer simulation models which predict growth, development and yield of agronomic and horticultural crops require daily weather data as input. One of these inputs is daily total solar radiation, which in many cases is not available owing to the high cost and complexity of the instrumentation needed to collect the data. In this work, a neural network model of the solar radiation over Abuja, Nigeria is developed. The model …

Study of Energy Injection during Intense and Super Intense Geomagnetic Storm Driven by Coronal Mass Ejection (CME)
Abstract: We have studied the energy injection process associated with CME driven storms that occurred during 18th February 1998, 4th May 1998, 16th July 2000 and 20th November 2003. The energy injection efficiency was parameterized by the ԑ parameter as a measure of the energy transfer of solar wind into the magnetosphere; we observed that intensification of ring current (Dst) depends on the energy injection into the magnetosphere and the duration …
