Effect of Atmospheric Aerosol on Lightning Activity Over North East India
Abstract: The observations of the lightning activity variation from 1998 to 2011 due to atmospheric aerosol effect over the North East India have been reported here. It has been observed that the lightning activity increases very rapidly in this region with a rate of 867 lightning flashes per year. Lightning activity over this region mainly occurs in two periods—March to June and August to October every year. As the higher lightning …

Performance Analysis of Efficient Channel Coding Schemes for Deep Space and Interplanetary Missions
Abstract: This paper discusses about the space communication challenges – especially deep space communications with a detailed analysis on channel coding techniques and modulation schemes. It explains about the free space loss (FSL) that occurs due to the presence of long distances (in terms of Astronomical Units) in AWGN channel with relation to the power transmitted and power received. Also, it discusses different kinds of digital modulation techniques employed in tandem …

System Design for High Speed Trajectory Changing of A Solar Sail
Abstract: Solar sails were created as a new form of satellite propulsion which uses the radiation pressure of the light from the stars or a laser to push ultrathin mirrors to high speeds. The new design incorporates ablative laser propulsion for trajectory changing of the probe at a desired point in space to be maneuvered towards the desired object. The design provides a combination of sail propulsion and laser propulsion systems …

Morphological Dynamics of Chilika Lake Inlet – Odisha
Abstract: Due to erosion and/or sedimentation of Chilika Lake Inlet Dynamics could be studied by using the Satellite images. Satellite imagery has an important role in studying the dynamics of the inlet. The current study was carried out to investigate spatio-temporal inlet dynamics due to erosion and/or sedimentation by using Remote Sensing and GIS Technique. The study period is between the year 2008 and 2014 of Chilika Lake because in this …
