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.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
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.

2. What is a Sensor?
A device that measures a physical variable (e.g.
force, pressure, temperature, velocity, flow rate,
etc.)
And converts the physical quantity into another
form
Which can be read by an observer or by an
instrument.
The most common conversion is to electrical form
as the converted signal is more convenient to use
and evaluate.
3. General Electronic Sensor
• Primary Transducer: changes “real world” parameter into electrical signal
• Secondary Transducer: converts electrical signal into analog or digital
values

Why Sensors are Required?
11. Sensors used in Robotics
The sensors used in robotics include a wide range of
devices which can be divided into following categories:
Tactile Sensors
Proximity and Range sensors
Miscellaneous sensors and sensor based
systems
Machine vision systems
12. Tactile Sensors
Tactile sensors are devices which indicate contact
between themselves and some other solid object.
Tactile sensing devices can be divided into two
classes: Touch sensors and Force sensors.
13. Touch Sensors
force voltage
measurement
electrical flow
a simple
switch
• Touch sensors provide a binary output signal
which indicates whether or not contact has been
made with the object without regard to the
magnitude of the contacting force.
14. Force Sensing
• Force sensor (also known as stress sensor)
indicate not only that contact has been made
with the object but also the magnitude of the
contact force between the two objects.
Metal foil strain-gauge based (load cell)
Good in low frequency response
High load rating
Resolution lower than piezoelectricity-based
Rugged, typically big size, heavy weight
15. Force Sensing
Piezoelectricity based (force sensor)
lower cutoff frequency at 0.01 Hz
can NOT be used for static load measurement
Good in high frequency
High resolution
Limited operating temperature (can not be
used for high temperature applications)
Compact size, light
16. Proximity and Range Sensors
Proximity sensors are devices that indicate when
one object is close to another object.
Some of these sensors can also be used to measure
the distance between the object and the sensor, and
these devices are called Range sensors.
Range sensors would be useful for determining the
location of an object(e.g., the work part) in relation
to robot.
18. Eddy Current Detector
device that emits an alternating magnetic field
at the tip of a probe, which induces eddy
currents in any conductive object in the range
of the device.
19. Photometric sensor
used to sense light. category includes photocells ,
photoelectric transducers ,photo tubes,
phototransistor and photoconductors. Can be used
to indicate presence or absence of an object.
20. Optical Pyrometer
device used to measure high temperatures by
sensing the brightness of an object’s surface.
Can be used to indicate presence or absence of
an object.
21. Vacuum Switches
device used to indicate negative air pressures.
Can be used with a vacuum gripper to indicate
presence or absence of an object.
22. Miscellaneous Sensors and Sensor
Based Systems
The miscellaneous category covers the remaining
types of sensors that might be used for interlocks
and other purposes in manufacturing work cells.
This category includes devices with the capability
to sense variables such as temp., pressure, fluid
flow, and electrical properties.
23. Types of Miscellaneous Sensor
• Ammeter: Electrical meter used to measure electrical
current.
• Linear variable differential transformer:
Electromechanical transducer used to measure linear
or angular displacement.
• Ohmmeter: used to measure electrical resistance.
• Potentiometer: Electrical meter used to measure
voltage.
24. Types of Miscellaneous Sensor
• Piezoelectric accelerometer: sensor used to indicate or
measure vibration.
• Pressure transducer: Various transducers used to
indicate air pressure and other fluid pressures.
• Thermistor : device based on electrical resistance used
to measure temperatures.
• Thermocouple: used to measure temperatures. Based
on the principle that a junction of two dissimilar metals
will emit an emf which can be related to temperatures.
25. Machine Vision System
Vision sensors: Advanced sensor system used
together with pattern recognition and other
techniques to view and interpret events
occuring in the robot workplace.

29. Distance Sensing
• Sensors for such application are of two types,
either contact type or non contact type.
•Contact type sensors are like dial gauge, gauge
blocks, pins, etc. However these sensors have a
limitation of wear and tear, and are not very
commonly used.
•Non contact types may be inductive, acoustic,
capacitive or optical sensors.
30. Contour tracking:
This is a kind of scanning process and is performed
by using electrical sensors such as inductive and
capacitive ones and optical sensors mostly laser
based scanners.
Machine Vision:
Here also tactile arrays and ultrasonic scanning
serve some useful purpose. Besides optical systems
with binary vision, grey level sensing and
stereovision are widely used.
31. Machine Diagnosis:
Well known sensors are used to measure forces,
torque, strain, frequency and a lot of other
indirect diagnostic data.
Process Parameters Monitoring:
Parameters such as pressure, force, speed,
temperature, fluid levels, chemical composition
and pH value data are measured in different
environmental conditions.
