Remote sensing is the science of obtaining information about objects through analysis of sensor data without physical contact. Electromagnetic radiation is used for remote sensing and propagates as waves through the electromagnetic spectrum. Platforms for remote sensing include ground, aerial, and space-based sensors. Spaceborne sensors on satellites provide large area coverage at regular intervals. Common satellite sensors discussed are Cartosat, RISAT, MODIS, and ASTER.
Remote sensing uses sensors on platforms like satellites and aircraft to detect and record electromagnetic radiation from the Earth's surface without physical contact. It works by sensing, recording, and processing reflected or emitted energy. Remote sensing provides information about the environment, allows for mineral exploration and natural hazard monitoring, and supports applications like land use mapping. It has advantages over traditional ground-based data collection in allowing rapid, non-destructive assessment of large areas.

Remote Sensing platforms and types of RS.pptxaaravpatel9794
There are three main types of remote sensing platforms: ground-based, airborne, and spaceborne. Ground-based platforms provide detailed surface information but have a small coverage area. Airborne platforms like airplanes and helicopters can operate at varying altitudes for very high resolution images but are affected by weather. Spaceborne platforms on satellites provide global coverage but have lower resolution as they operate from outside the Earth's atmosphere. The document then discusses different classifications of remote sensing based on the platform, energy source, imaging media, spectral region, and number of spectral bands collected.
Remote sensing is the process of detecting and monitoring the physical characteristics of an area by measuring its reflected and emitted radiation at a distance (typically from satellite or aircraft).
Special cameras collect remotely sensed images, which help researchers "sense" things about the Earth.

This documentation details the design of a Distributed Web content caching system in a LAN, using the SDN OpenFlow model. This system was successfully implemented on GENI (Global Environment for Network Innovations) to test the performance improvements.
This distributed web-caching helps reduce access delays of frequently requested web content (web pages, files - pdfs, images,etc.) within the LAN by more than 50% compared to a LAN without this caching system. Further, this model helps in reducing load on the access links as every repeated request need not be fetched from the main server located in some other geographical area.
The distribution of caching servers in the LAN aim at load balancing the requests and also tackle the issue of single point of failure as in a centralized caching system.

A polygraph, commonly known as a lie detector, measures a person's physiological responses like breathing, pulse, blood pressure, and perspiration when answering questions. It was developed in the early 20th century and works by detecting changes in the autonomic nervous system which controls involuntary body functions. However, polygraph results are not completely reliable and accuracy depends on the quality of the test being administered. Error rates have been estimated to be as high as 40% depending on the study. Some individuals may be wrongly identified as lying or certain trained persons can pass the test despite being deceptive.

Accident detection system project report.pdfKamal Acharya
The Rapid growth of technology and infrastructure has made our lives easier. The
advent of technology has also increased the traffic hazards and the road accidents take place
frequently which causes huge loss of life and property because of the poor emergency facilities.
Many lives could have been saved if emergency service could get accident information and
reach in time. Our project will provide an optimum solution to this draw back. A piezo electric
sensor can be used as a crash or rollover detector of the vehicle during and after a crash. With
signals from a piezo electric sensor, a severe accident can be recognized. According to this
project when a vehicle meets with an accident immediately piezo electric sensor will detect the
signal or if a car rolls over. Then with the help of GSM module and GPS module, the location
will be sent to the emergency contact. Then after conforming the location necessary action will
be taken. If the person meets with a small accident or if there is no serious threat to anyone’s
life, then the alert message can be terminated by the driver by a switch provided in order to
avoid wasting the valuable time of the medical rescue team.
Home security is of paramount importance in today's world, where we rely more on technology, home
security is crucial. Using technology to make homes safer and easier to control from anywhere is
important. Home security is important for the occupant’s safety. In this paper, we came up with a low cost,
AI based model home security system. The system has a user-friendly interface, allowing users to start
model training and face detection with simple keyboard commands. Our goal is to introduce an innovative
home security system using facial recognition technology. Unlike traditional systems, this system trains
and saves images of friends and family members. The system scans this folder to recognize familiar faces
and provides real-time monitoring. If an unfamiliar face is detected, it promptly sends an email alert,
ensuring a proactive response to potential security threats.

2. INTRODUCTION
• Infrared (IR) Imaging from Satellites is an advanced field of space
science and technology
• The first satellite with thermal imaging capability was by
NOAA/NASA in 1970’s
• Images are generated by emitted IR radiation from the Earth surface

forest fires, and many more applications
3. GEOSTATIONARY SATELLITES (GEO-S) FOR IR
IMAGING
• GEO-S placed in geostationary Earth orbit
or geosynchronous equatorial orbit (GEO) circular orbit 35,786
kilometers above the Earth's equator and following the direction of
the Earth's rotation
• GEO-S Imaging sensors can see 1/3 of the earth sphere only, centered
with the satellite location
• USA, Europe, India, Japan, China have deployed operational GEO-S
for earth imaging, mainly for meteorological applications
4. IR IMAGING SENSOR TYPES
A. Imager/Radiometer
• Imagers provide images for the entire Earth disc or a part of it.
• They have much wider bands, and fewer imaging channels
• Resolutions are 500mts-2.5km
• Imaging intervals can be 1min to 20 min.
• Generally 48 or more images can be generated and transmitted per
day
5. IR IMAGING SENSOR TYPES
B. Sounder
• Special type of multi band IR sensor.
• Related with emission or absorption of EM/IR radiation of
atmospheric water vapor, CO2, Ozone.
• Sounder instruments have resolutions of 4-10km
• Provide up to 6-8 images per day.
6. CONSTITUENTS OF A SATELLITE IR IMAGING
SENSOR
A.Telescope and Scanning systems
• Telescope configuration: Cassegrain or RC type
• Focal length that covers the Earth disc and its surrounding space
• The primary mirror can be “scooped” to make it light-weighted
• “Scan Mirror” is required to be placed before the telescope
7. CONSTITUENTS OF A SATELLITE IR IMAGING
SENSOR
B. Pre – detector optical system
• Several IR imaging detectors are required to cover the different IR
bands, to provide the images of features on Earth
• “Beam splitters” are placed, to only transmit that part of the IR
radiation required for a specific detector
• e.g. Gold di-chorics are used with different thickness to split 8-14um
bands and glass filters are also used for 2.5-14 um radiation bands
8. CONSTITUENTS OF A SATELLITE IR IMAGING
SENSOR
C. Electronic IR Detectors and Cryogenic coolers
• There are two basic types of photon (radiative energy)
detectors:
1. Majority (electron): detector is photoconductive
2. Minority (hole): detector is both photoconductive and
photovoltaic
• Most GEO satellites with IR imaging use cryogenic cooled
HgCdTe (photoconductive) detector
• IR detectors being photoconductive, the performance is
governed by Planck’s radiation law, Stephan-Boltzzman
black body law, and ElectronicWork Function law.
• The detector elements have to be operated at the lowest
possible cryogenic temperatures to obtain meaningful
electronic signal
9. THERMAL CONTROL SYSTEM
• This system is cardinal to achieve optimum performance and
it ensures efficient equipment operation
• The generated heat is transferred by TCS from the
spacecraft or space station to the space.
• The TCS system has two subsystems – a Passive Thermal
Control System (PTCS) and an Active Thermal Control
System (ATCS).
• The cooling mechanism in GEO satellites can be of two
types:
1. Active, using cryogenic electro-mechanical coolers (sterling cycle)
2. Passive, using radiant cooler
