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!

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.

3. INTRODUCTION
Vision is the most important part of human
physiology as 83% of information human being gets
from the environment is via sight. The 2011 statistics
by the World Health Organization (WHO) estimates
that there are 285 billion people in world with visual
impairment, 39 billion of which are blind and
246 with low vision.
Presently, blind people use a white stick as a tool for
directing them when they move or walk.
Here, we develop a tool which can serve as a blind
stick being more efficient and helpful than
the conventional one.
This will assist the blind persons during the walk and
provides an alarm if any hurdle is detected within the
set range.

8. USAGE OF DIFFERENT SENSORS
• Ultrasonic sensor is used for obstacle avoidance. The vibrator
vibrates when an obstacle is encountered which helps in alerting the blind
person and allows enough time to change their path.
• Water sensor is used to detect the presence of water and provide an alert
in time for path change so as to avoid slipping.
• Light sensor is useful at night. It alerts the people in the surrounding area
that a blind person is walking and to allow space so that the blind person
can walk easily.

LED
It is a p–n junction diode, which
emits light when activated. When
a suitable voltage is applied to
the leads, electrons are able
to recombine with electron
holes within the device, releasing
energy in the form of photons.
This effect is called
electroluminescence, and the color
of the light is determined by the
energy band gap of the
semiconductor.
14. OUTPUT DEVICES
VIBRATOR
•A vibrating motor is essentially a motor that is improperly balanced.
In other words, there is an off-centered weight attached to the motor's
rotational shaft that causes the motor to wobble. The amount of wobble can
be changed by the amount of weight attached, the weight's distance from
the shaft, and the speed at which the motor spins.
•Vibrating motors can be found inside cell phones, pagers, gaming
controllers, and personal massagers
17. CONCLUSION
• The project proposed the design and architecture of a new concept
of Smart Electronic Guiding Stick for blind people. The advantage of
the system lies in the fact that it can prove to be very low cost
solution to millions of blind person worldwide. The proposed
combination of various working units makes a real-time system that
monitors position of the user and provides dual feedback making
navigation more safe and secure.
• It can be further improved to have more decision taking capabilities
by employing varied types of sensors and thus could be used for
different applications. It aims to solve the problems faced by the blind
people in their daily life. The system also takes measures to ensure their
safety.
18. FUTURE SCOPE
It can be further enhanced by using VLSI technology to design the PCB
unit. This makes the system further more compact. Also, use of active
RFID tags will transmit the location information automatically to the PCB
unit, when the intelligent stick is in its range. The RFID sensor doesn’t
have to read it explicitly.
The global position of the user is obtained using the global positioning
system (GPS), and their current position and guidance to their destination
will be given to the user by voice.
