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.

Fittings and Fastenings of Rails.pdf
1. TRACK FITTINGS AND FASTENINGS
By
Dr. T. Vijaya Gowri
Associate Professor,
B. V. Raju Institute of Technology
2. Definition
All those fittings which
are required for
connecting the rails end
to end and for fixing the
rails to the sleepers in a
track are known as
fixtures and fastenings.
3. Purpose of Track Fittings And Fastenings
1.The purpose of providing fittings and
fastenings in railway tracks is to hold the rails
in their proper position in order to ensure the
smooth running of trains.
2.These fittings and fastenings are used for
joining rails together as well as fixing them to
the sleepers.
3. They serve their purpose so well that the
level, alignment, and gauge of the railway
track are maintained within permissible limits
even during the passage of trains.
4. Functions of Track Fittings And Fastenings
The different functions of these fitting
are :
1) To keep the rails in the proper
positions.
2) Connection of rail to rail.
3) To set points and crossings properly
4) To allow for expansion and
contraction of rails.
5. Types of Track Fittings
They include
1) Fish plates
2) Spikes
3) Bolts
4) Chairs
5) Keys
6) Blocks
7) Bearing plates

Keys
Blocks
Bearing plates
6. FISH PLATES
◦ These plates are used to maintain proper
alignment of the rail line.
◦ They maintain the continuity of the rails
and also allow expansion or contraction of
rails caused due to temperature variations.
◦ Generally these plates are made of mild
steel and 20 mm in thickness.
◦ They are 45.6 cm long and provided with 4
no. of 32 mm diameter holes at 11.4 center
to center.
7. FISH PLATES
◦ Indian railways generally adopt
following two types of fish plates :
1) Bone shaped fish plate
2) Increased depth fish plate
◦ Bone shaped fish plate is used for
connecting flat footed rails.
◦ The increased depth fish plate is
generally used for connecting
Bull-headed rails.
8. Common types of Fish Plates-Joggled Fish Plate
◦ This is a specially forged fish plate. It is
suitable for the temporary repair of
cracked welded rail joints with clamp
assembly to suit various rail sections.
◦ Used as an emergency clamp, joggled
fish plate enables quick and temporary
repair, allowing continued movements
through the section at a reduced line
speed.
9. Common types of Fish Plates-Compromise
Fish Plate
◦ These are designed fish
plates to join two
different rail sections of
rail tracks for various
customers when they
require them.
10. SPIKES
◦ They are used to hold the rails to the
wooden sleeper.
◦ A good spike should have following
qualities :
◦ 1) It should have sufficient strength
to hold the rail in position.
◦ 2) It should help in maintaining
proper gauge.
◦ 3) It should be easy to fix and
replace from the sleepers.
11. SPIKES
◦ Indian Railways use following
types of spikes :
1. Dog spikes
2. Screw spikes
3. Standard spikes
4. Elastic spikes
12. Dog spikes
◦ A dog spike, also called cut
track spike, is often used to
fasten T-shaped railway
track to wooden sleepers,
to secure a rail and tie
plate to the ties in track,
which has a pointed
penetrating head with
square shank, and the
underside of the spike head
is sloped to compromise
the top of the rail base.
13. Screw spikes
◦ Rail screw spikes (also
called sleeper screws or
square head rail bolts)
are medium or large
metal screws used to
fasten rail tie plates
and rail track on the
wooden or concrete
sleepers.
14. Standard Spikes
◦ The common track spikes
are the 5/8”*6” and the
9/16”*5-1/2” for smaller
rail sections, and they are
usually secured in either
200 lb. kegs or 50 lb. kegs.
15. Elastic Spike
◦ There’s a special rail spike called
elastic spike. The elastic spikes are
made of spring steel.
◦ There’re double shank elastic spike
and single shank screw spike.
◦ The single shank elastic rail spike is
manufactured by shearing the
double shank elastic rail spike
16. BOLTS
They are used for connecting :
1) Fish plates to the rails at
each rail joint.
2) Chairs or bearing plates to
timber sleepers.
3) Sleepers to bridge
girders,etc
17. BOLTS
The different types of bolts used in
Indian Railways are :
1. Hook bolts
2. Fish bolts
3. Fang bolts
4. Rag bolts
Rag bolts
18. BOLTS
◦ Hook bolts are used for fixing timber
sleepers to bridge girders. They are
popularly known as dog bolts.
◦ Fish bolts are used to connect fish plates
to the rails at rail joints.
◦ Fang bolts are used for fixing side chairs to
the sleepers.
◦ Rag bolts are generally used to connect
longitudinal timber sleeper or concrete
sleepers to the walls of ash pits.
Hook bolts Fish bolts
Fang bolts Rag bolts
19. CHAIRS
◦ They are used to hold the double
headed and bull headed rails in
required position.
◦ They are made of cast iron having
two jaws and a rail seat.
◦ In order to fix the double headed
or bull headed rail to a chair, the
rail is placed between the two
jaws of the chair.
◦
21. KEYS
They are small tapered pieces of
timber or steel to connect rails to
chairs on metal sleepers.
Types of keys generally used are :
1) Timber keys
2) Metal keys
3) Stuart's keys
4) Morgan keys
22. BLOCKS
◦ They are inserted in between
the two rails running close to
each other and bolted to
maintain the required distance
◦ They may touch either the
webs or the finishing faces or
both.
23. BEARING PLATES
◦ They are the plates placed in
between the flat footed rails
and timber sleepers on a track.
◦ They serve as chairs for flat
footed rails. They are made of
cast iron, wrought iron or steel.
24. BEARING PLATES
◦ Generally, they are of following types :
1) Flat bearing plates
2) canted bearing plates
◦ Flat bearing plates are used at locations
where rails are laid flat. Also they are used
in turn out tracks under points and
crossings.
◦ Canted Bearing plates are used on soft
timber sleepers beneath outside rail on
curves, on sleepers placed on either side of
rail joints, bridges etc. where rails are laid at
an inward tilt of 1 in 20.
