This document discusses adaptive optics in ground-based telescopes. It begins by explaining that adaptive optics helps remove atmospheric distortions to provide clearer images from telescopes on Earth. It then describes the three main types of telescopes - optical, reflecting, and radio telescopes. The document focuses on how adaptive optics works, using a deformable mirror and wavefront sensor to counteract distortions in real time. It discusses challenges like developing sensitive infrared detectors and fast adaptive components to enable observing faint exoplanets and other celestial objects.

Astronomy from the Moon: From Exoplanets to Cosmology and Beyond in Visible L...Sérgio Sacani
We review what could be astronomy from the Moon in the next decades in the visible domain.
After a short review observational approaches, from photometry to high contrast and high angular
resolution imaging, We essentially focus on some promising scientific objectives, from Solar
System to the extragalactic domain. At the end, I add a proposal to use the Earth-Moon system to
test fundamental physics. Since this meeting is dedicated to the next decades of Astronomy from
the Moon, we consider projects and science objectives for several decades from now.
The extremely high albedo of LTT 9779 b revealed by CHEOPSSérgio Sacani
Optical secondary eclipse measurements of small planets can provide a wealth of information about the reflective properties
of these worlds, but the measurements are particularly challenging to attain because of their relatively shallow depth. If such signals
can be detected and modeled, however, they can provide planetary albedos, thermal characteristics, and information on absorbers in
the upper atmosphere.
Aims. We aim to detect and characterize the optical secondary eclipse of the planet LTT 9779 b using the CHaracterising ExOPlanet
Satellite (CHEOPS) to measure the planetary albedo and search for the signature of atmospheric condensates.
Methods. We observed ten secondary eclipses of the planet with CHEOPS. We carefully analyzed and detrended the light curves using
three independent methods to perform the final astrophysical detrending and eclipse model fitting of the individual and combined light
curves.
Results. Each of our analysis methods yielded statistically similar results, providing a robust detection of the eclipse of LTT 9779 b
with a depth of 115±24 ppm. This surprisingly large depth provides a geometric albedo for the planet of 0.80+0.10
−0.17, consistent with
estimates of radiative-convective models. This value is similar to that of Venus in our own Solar System. When combining the eclipse
from CHEOPS with the measurements from TESS and Spitzer, our global climate models indicate that LTT 9779 b likely has a super
metal-rich atmosphere, with a lower limit of 400× solar being found, and the presence of silicate clouds. The observations also reveal
hints of optical eclipse depth variability, but these have yet to be confirmed.
Conclusions. The results found here in the optical when combined with those in the near-infrared provide the first steps toward
understanding the atmospheric structure and physical processes of ultrahot Neptune worlds that inhabit the Neptune desert.
Students determined the age of the universe using an 11 inch telescope and they discover the necessary physical laws experimentally.
As a second step they developed a progressive series of mathematical models for the dynamics of the universe and calculated that the usual matter amounts only 5 % of all matter and energy in the universe.
Easy to use learning material is included for schools as well as for the interested public. More detailed learning material may be requested. The material has been tested successively for three age groups: With the conceptual material, students of classes 4 or higher can comprehend the topic. With more advanced material, students of class 7 or higher can evaluate the measurements mathematically. With fully advanced material, students of class 9 or higher can develop mathematical models for the dynamics of the universe and calculate the statistical significance of the measurements.
The European Extremely Large Telescope (E-ELT) is motivated by a wide range of scientific Challenges Encountered by modern astronomy. This project belongs to European astronomers who are planning to build an optical telescope that is four times larger than any other in today.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

Adaptive optics on ground based telescope
1. ADAPTIVE OPTICS IN GROUND
BASED TELESCOPE
Guided by: Presented by:
V P Vinturaj Ajeesh . K. V
Lecturer in Electronics S5 EL, ROLL NO:03
Dept . of EL,GPTC. kasaragod 1
3. INTRODUCTION
Adaptive optics is new technology which in effect
removes the atmosphere tremor and helps the
astronomer see the image through earth based
telescopes more brightly.
Without using this system the image obtained in
telescope on earth are seen to be blurred, which is
caused by the turbulent mixing of air at different
temperatures .
It brings together the latest in computers, materials
science, electronic detectors and digital control in a
system that warps and bends a mirror in a telescope to
counteract in real time the atmospheric distortion.
Dep . Of EL, GPTC. Kasaragod 2
4. TELESCOPES
Telescopes are instruments used to study the
electromagnetic radiations from the universe.
The word telescope is derived from the Greek
words “tele” (from afar)and “skopos” (viewer).
The underlying principle of all telescopes is to
gather radiation from distant objects and focus it.
This increases the intensity of the radiations thereby
allowing the objects to be magnified.
Dept . of EL, GPTC. Kasaragod 3
5. THREE DIFFERENT TYPES OF
TELESCOPES
Optical telescope
Reflecting telescope
Radio telescope
Dept . Of EL, GPTC. Kasaragod 4
6. Optical Telescopes
An optical telescope is a telescope that gathers
and focuses light, mainly from the visible part of the
electromagnetic spectrum, to create
a magnified image for direct view, or to make
a photograph, or to collect data through
electronic image sensors.
Optical telescopes have been used in astronomical
research since the time of their invention in the early
17th century.
Many types have been constructed over the years
depending on the optical technology, such as
refracting and reflecting etc.
Dept . Of EL, GPTC. Kasaragod 5
8. Reflecting Telescopes
A reflecting telescope (also called a reflector) is
a telescope that uses a single or a combination
of curved mirrors that reflect light and form an image.
The reflecting telescope was invented in the 17th
century, by Isaac Newton, as an alternative to
the refracting telescope which, at that time, was a
design that suffered from severe chromatic aberration.
Reflecting telescopes come in many design variations
and may employ extra optical elements to improve
image quality or place the image in a mechanically
advantageous position.
Dept . of EL, GPTC. kasaragod 7
10. Radio Telescopes
A radio telescope is a specialized antenna and radio receiver used
to receive radio waves from astronomical radio sources in the sky
in radio astronomy.
Radio telescopes are the main observing instrument used in radio
astronomy, which studies the radio frequency portion of
the electromagnetic spectrum emitted by astronomical objects, just
as optical telescopes are the main observing instrument used in
traditional optical astronomy which studies the light wave portion
of the spectrum coming from astronomical objects.
Radio telescopes are typically large parabolic ("dish")
antennas similar to those employed in tracking and communicating
with satellites and space probes. They may be used singly or
linked together electronically in an array.
Unlike optical telescopes, radio telescopes can be used in the
daytime as well as at night.
Dept. of EL, GPTC. Kasaragod 9
12. What isAdaptive optics ?
Adaptive optics refers to optical system which
adapt to compensate for optical effects introduced
by the medium between the object and its image
In order to avoid atmospheric aberration one can
turn to large telescope on the ground, which have
been equipped with ADAPTIVE OPTICS system.
With this setup, the image quality that can be
recovered is closed to that the telescope would
deliver if it were in space
Dept . of EL, GPTC. Kasaragod 11
13. BASIC PRINCIPLES
An adaptive system refracts the wave fronts by
reflecting the light of a deformable mirror whose
shape is changed in real time to introduce an
equal but opposite distortion
The information on how to distort the mirror
comes from a wave front sensor an instrument
that measures optical aberration imposed by the
atmosphere on light from a star.
After the light reflects of the deformable mirror, a
beam splitter sends part of the light to a camera
that will capture the high resolution image
produced by the adaptive optics.
Dept . of EL, GPTC. Kasaragod 12
16. SEEING INFRARED
In the infrared, the hardware of adaptive optics
consists of an existing telescope, complete with
its primary and secondary mirrors, and adds a
separate box of optics, including the deformable
mirror, to perform the atmospheric compensation.
One is that each additional optical surface beam
train absorbs some of the light from the target
object in the sky, making the object appear fainter.
Also it emits light by virtue of its warmth ,
introducing thermal noise, further degrading the
astronomers, ability to detect faint objects
Dept . of EL, GPTC. Kasaragod 15
17. OTHER STARS, OTHER EARTHS
Per haps the most exciting scientific program to
benefit from the new approach to adaptive optics
will be to look at Jupiter like planets orbiting
other stars.
Roughly 100 such stars have been found out
through observation of the effects on the motion
of there parent stars, but none has ever be seen by
direct imaging.
It happens because they are extraordinary faint
and to compound the problem, they are right next
to something that is enormously brighter
Dept . of EL, GPTC. Kasaragod 16
18. CONCLUSION
There are many substantial technological challenges
in AO.
Among them are the development of fast, very low-
noise detectors in order to be able to correct with
fainter reference stars; high-power reliable & easy to
operate sodium lasers, very fast processors exceeding
109 to 1010 operations per second; deformable
mirror with bandwidths of actuators and large
secondary adaptive mirror.
The latter are especially interesting at thermal wave
lengths, where any additional mirror raises the
already huge thermal background seen by the
instruments
