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.

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.
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.

What Is A Scaffold?
An elevated, temporary work platform
Three basic types:
Supported scaffolds -- platforms
supported by rigid, load bearing
members, such as poles, legs,
frames, & outriggers
Suspended scaffolds -- platforms
suspended by ropes or other non-
rigid, overhead support
Aerial Lifts -- such as “cherry
pickers” or “boom trucks”
3. OSHA Office of Training & Education 3
Hazards
• Falls from elevation – caused
by slipping, unsafe access, and
the lack of fall protection
• Struck by falling tools / debris
• Electrocution – from overhead
power lines
• Scaffold collapse - caused by
instability or overloading
• Bad planking giving way
Employees working on scaffolds are
exposed to these hazards:
4. OSHA Office of Training & Education 4
Fall Hazards
• While climbing on or off
the scaffold
• Working on unguarded
scaffold platforms
• When scaffold
platforms or planks fail
Falls may occur:
5. OSHA Office of Training & Education 5
Protecting Workers from Falls
• Guardrails, and/or
• Personal Fall Arrest
Systems (PFAS)
If a worker on a scaffold
can fall more than 10
feet, protect them by:
6. OSHA Office of Training & Education 6
Install along open sides & ends
Front edge of platforms not
more than 14 inches from the
work, unless using guardrails
and/or PFAS
Top rails - 38 to 45 inches tall
Midrails halfway between
toprail and platform
Toeboards at least 3-1/2 inches
high
Guardrails
7. OSHA Office of Training & Education 7
Personal Fall Arrest Systems (PFAS)
You must be trained how to properly use PFAS
PFAS include anchorage, lifeline and body harness.
8. OSHA Office of Training & Education 8
Can use PFAS instead of
guardrails on some
scaffolds
Use PFAS & guardrails on
suspension scaffolds
Use PFAS on erectors and
dismantlers where feasible
Fall Protection Requirements
The ends of this scaffold
are not properly guarded
9. OSHA Office of Training & Education 9
Falling Object Protection
Wear hardhats
Barricade area below scaffold
to forbid entry into that area
Use panels or screens if
material is stacked higher than
the toeboard
Build a canopy or erect a net
below the scaffold that will
contain or deflect falling objects
10. OSHA Office of Training & Education 10
Overhead Power Lines
The possibility of
electrocution is a
serious consideration
when working near
overhead power lines
Check the clearance
distances listed in the
standard
11. OSHA Office of Training & Education 11
Scaffold Support Examples
Good support Inadequate support –
in danger of collapse?
Base plate
Mud sills
12. OSHA Office of Training & Education 12

Scaffold Platform Construction
Platforms must:
• be fully planked or
decked with no
more than 1 inch
gaps
• be able to support
its weight & 4 times
maximum load
• be at least 18
inches wide
This is not a properly
constructed scaffold
14. OSHA Office of Training & Education 14
• No large gaps in front
edge of platforms
• Each abutted end of
plank must rest on a
separate support
surface
• Overlap platforms at
least 12 inches over
supports, unless
restrained to prevent
movement
Scaffold Platform Construction
Planks not properly
overlapped
15. OSHA Office of Training & Education 15
Scaffold Platform Construction
• No paint on wood platforms
• Use scaffold grade wood
• Fully planked between front
upright and guardrail support
• Component pieces used must
match and be of the same type
• Erect on stable and level ground
• Lock wheels and braces
16. OSHA Office of Training & Education 16
Scaffold Height
The height of the
scaffold should
not be more than
four times its
minimum base
dimension unless
guys, ties, or
braces are used
20’
5’
17. OSHA Office of Training & Education 17
Platform Ends
Each end of a
platform, unless
cleated or otherwise
restrained by hooks,
must extend over its
support by at least 6
inches
No Cleats
18. OSHA Office of Training & Education 18
Supported Scaffolds
Platforms supported by legs,
outrigger beams, brackets,
poles, uprights, posts, & frames
Restrain from tipping by guys,
ties, or braces
Scaffold poles, legs, posts,
frames, and uprights must be
on base plates and mud sills or
other firm foundation
This support is not adequate!
19. OSHA Office of Training & Education 19
Proper Scaffold Access
Provide access when scaffold
platforms are more than 2 feet
above or below a point of access
Permitted types of access:
• Ladders, such as portable, hook-
on, attachable, stairway type, and
built-ins
• Stair towers
• Ramps and walkways
May use building stairs and come
out window
20. OSHA Office of Training & Education 20
Scaffold Access
• No access by
crossbraces
• When using
ladders, bottom
rung no more than
24 inches high
• Can use some end
frames
• Can access from
another scaffold,
structure or hoist
End Frame
Do not access
by crossbraces
21. OSHA Office of Training & Education 21
Suspension Scaffolds
Train employees to recognize hazards
Secure/tie to prevent swaying
Support devices must rest on surfaces
that can support four times the load
Competent person:
evaluate connections to ensure the
supporting surfaces can support load
inspect ropes for defects before shift
PFAS must have anchors independent
of the scaffold support system
Platforms suspended by ropes or wires. Rope must be capable
of supporting 6 times the load
22. OSHA Office of Training & Education 22
Moving Scaffolds

• Outriggers are installed on
both sides of scaffolds
Employees can’t be on scaffold
part beyond the wheels
Competent person must be on
site to supervise
23. OSHA Office of Training & Education 23
Fatal Fact – Moving a Lift
Employee was operating an
aerial lift, with an extendable
boom rotating work platform
The boom was fully extended
and the machine apparently ran
over some bricks, causing the
boom to flex or spring, throwing
the employee from the basket
The employee fell 37 feet to a
concrete surface
24. OSHA Office of Training & Education 24
Don’t use Shore or Lean-to Scaffolds
Shore scaffold

which is placed
against a building
or structure and
held in place with
props
Lean-to scaffold
supported scaffold
which is kept erect
by tilting it toward
and resting it
against a building
or structure
25. OSHA Office of Training & Education 25
Using Scaffolds
• Don’t work on snow or ice
covered platforms or during
storms or high winds
• Use tag lines on swinging
loads
• Protect suspension ropes
from heat & acid
A covered scaffold has special
wind load considerations
26. OSHA Office of Training & Education 26
Fatal Fact – Ice & No Guardrails
Laborer was working on the
third level of a tubular welded
frame scaffold which was
covered with ice and snow
The scaffold was not fully
decked, there was no
guardrail and no access
ladder
The worker slipped and fell
head first 20 feet to the
pavement below
27. OSHA Office of Training & Education 27
