to see inside a structure to determine the basic layout of buildings, where there may be occupants and other objects. This concept has SIMRANJEET SINGH (14116066) ECE DEPARTMENT, IIT ROORKEE Praveenfun2@gmail.com evolved from ground penetrating radar systems applied to walls and many applications since 1990’s have been developed to sense beyond a wall from near range. These approaches revolve around basic wave physics to form matched filters for each and every single point in target space. Only

entire world was in shock when they heard that Flight 370 with its 239 passengers and crew vanished off the face of the earth. The airlines, media and even aviation experts were all perplexed about how such a sophisticated aircraft with tracking and radar systems could just disappear during a routine flight. Theories have emerged that the plane crashed into the ocean either by being set on auto pilot or by the actions of the aircrafts captain, or even that it was taken over by highly trained hijackers

change gave way to an immediate impact, this impact was felt most during one of the most violent times in America’s history, WWII. During this time the military had a priority to be able to navigate and break the conversation codes from the enemy. Radar in WWII was also much more accurate. In a very real sense, electronic implementation and computer technology came at just the right time, and was a small cornerstone for the American Military. Mechanical devices when compared to pure electronic computation

In the start of WWII that nations came up with many ways to communicate to each other without being intercepted by the enemy.Some ideas/inventions used during World War II included foot, mounted, motorcycle, automobile, airplane, homing pigeons, and the messenger dog. Along with physically going to deliver a message they also had made visual messages. Which included flags, panels for airplanes, lights, and pyrotechnics. But when they didn't want to use those ways to signal messages they would send

caught the wind unfurling into a giant orange dome. “The egg is at one thousand feet.” The radar specialist called out. Everyone focused intently on the egg. “Mother Bird is safely out of the hot zone. Egg is at eight hundred feet.” The radar specialist said. “Here we go.” whispered Sergeant Barnes. “Seven hundred feet, the egg is hot.” informed the radar specialist, meaning that the bomb was now armed. The room held silent. Commander

modern communication devices, and day-to-day communication is done through it. Study of literature of past few year shows that, the leading work on Microstrip Patch Antenna (MPA) is focused on designing for dual frequency and dual polarized operation on arbitrary shape of patch with commercially simulated software. This review paper demonstrates some commonly engaged techniques to fabricate Microstrip patch antenna with dual frequency and dual polarized operation since last few decades. Index Terms

Prior to atmospheric correction and radiometric calibration, both sentinel and Landsat 8 images were geo referenced to UTM 37N coordinate system (WGS 84 datum and Spheroid) and subset image was created. Landsat 8 image acquired in the form of digital number (DN) were converted to radiance and TOA reflectance values using ENVI 5.3 software. Atmospheric correction was also employed using dark object subtraction module of ENVI 5.3 (ExelisVisual Information Solutions, 2010). The DN of Sentinel-2A LIC

Since centuries, mobility have been the provocative issue for blind people or partially sighted people. Everybody including blind people needs to move. Hence there are some limitations with such devices as they are not much efficient. With the advancement of technology, several prototypes have been developed for blind assistance. They are usually known as blind stick. For the betterment of Pakistan and third world countries which are least developed proposing a user-friendly and cost effective

The National Plan of Integrated Airport Systems (NPIAS) forever changed the way airports were classified when it was unveiled in 1982 (Wells, 2011). The aviation industry had grown significantly since deregulation went into effect, and a new system needed to be put in place that would distinguish airports with incredible growth and expansion from those that served niche markets or flight training (Wells). Under the NPIAS, airports were broken down into three major categories: commercial services

Conclusion Satellite sensors send bits of binary data to ground stations on Earth for processing into useful meteorological and environmental information enabling enhanced decision making capabilities. Thereby, preventing injuries and fatalities, preserving assets, and reducing time delays. Binary data are comprised of zeroes and ones. One bit contains either a “0” or a “1”. A single bit, in and of itself, does not have a lot of value until it is used. The same is true of information. Information
