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.

75. Metals are versatile housing materials because they can be
shaped in so many ways. They are available in a variety of
natural colors or can be coated for a wider array of colors and
for added protection. Metals are strong, decorative, and good
conductors of heat and electricity.
CAST IRON is made of
iron and carbon, melted in
a furnace and cast into
shapes such as wood
burning stoves, bathtubs,
sinks, skillets, sewer lines,
waste disposal systems,
lawn furniture and gas
pipes.
WROUGHT IRON is
nearly pure iron used
for ornamental lawn
furniture, lighting
fixtures, fences, and
staircase/porch railings.
BRONZE is an alloy of
copper and tin, forming a
strong, beautiful, stately
material that weathers
well. It is used for
thresholds, screws,
plumbing supplies, and
decorative pieces
including sculpture.
76. ALUMINUM is lightweight, highly
resistant to corrosion, an excellent
conductor of electricity, a good
reflector of light and heat, easily
formed into many shapes, and
receptive to many finishes. Aluminum
can be “extruded” into window and
door frames, railings, and hardware. It
can also be “cast” into lamp bases,
plant stands, cookware, and grills. It
can be “rolled” into range hoods,
awnings, garage doors, appliance
panels, and ductwork.
COPPER is most important
for it’s electrical and heat
conductivity, and resistance
to corrosion. Exposed to
moist air, it becomes coated
with a thin layer of green
carbonate that protects it
from further corrosion. It is
used in wiring and roofing
materials, cookware, lamps,
and decorative pieces.
BRASS is an alloy of copper and
zinc, ranging in color from a
coppery red to silvery white. Tin
can be added or it can be coated
with clear enamel to prevent
tarnishing. Ir can be cast,
hammered, stamped, rolled, or
drawn into bolts, screws, pipe
fittings, wire, furniture, and
decorative pieces.
77. STAINLESS STEEL is
steel with chromium
added, making it hard
and corrosion resistant
over a wide
temperature range. It is
used for gutters,
downspouts, cooking
and eating utensils,
appliances, sinks,
countertops, and even
furniture.
LEAD is a heavy but
workable metal
resistant to corrosion. It
is used under showers
and as liners for pools,
and in drainage pipes.
It expands and
contracts in different
temperatures, and it
can cause lead
poisoning… limiting
many household
applications. It is used
in leaded window
designs.

107. Reinforced concrete (RC), also called
reinforced cement concrete (RCC):
It is a composite material in which concrete's
relatively low tensile strength and ductility are
compensated for by the inclusion of reinforcement
having higher tensile strength or ductility.
Steel reinforcements are often included to increase
the tensile. strength of concrete; such concrete is
called reinforced cement. concrete (RCC) or simply
reinforced concrete
108. Applications of Reinforced Concrete

columns, walls, floors, and roofs. ...
•Bridges. ...
•Roads. ...
•Floating Structures. ...
•Foundations. ...
•Marine Structure. ...
•Pipes and Conduits. ...
•Precast Works.

•Coarse Aggregates (Stone Chips/brick chips)
• Fine Aggregates (Crushed Stone or Sand)
• Water
111. Advantages of pre-stressed concrete.
• Factory products are possible.
• Reduction of steel corrosion
• Long span structure are possible so that saving of wt is significant & thus it
become economical.
• Pre-stressed member are tested before use.
• Dead load are get counter balanced by eccentric pre-stressing
• It has high ability to resist the impact.
• It has high fatigue resistance.
• It has high live load carrying capacity.
• It free from cracks from service loads and enable entire section to take
part in resisting moments.
• Member are free from the tensile stresses.
112. Disadvantages of pre-stressed concrete.
• Required skilled builders & experienced engineers.
• Initial equipment cost is very high.
• Availability of experienced engineers is less.
• Required complicated formwork.
• It requires high strength concrete & steel.
• Pre-stressed concreteA is less fiber resistant.
113. • Prestressed concrete was started to be used in building frames,
parking structures, stadiums, railway sleepers, transmission line
poles and other types of structures and elements.
Materials for pre-stress concrete member
1. Cement,
2. Concrete,
3. Steel.
# Cement:
# Ordinary portland cement,
# Portland slag cement,
# Rapid hardening portland cement,
# High strength ordinary portland cement.
114. # Concrete:
Pre-stress concrete requires high strength concrete, which
has high compressive strength comparatively higher tensile strength
than ordinary concrete.
The concrete is a material should be compose of gravels or
crushed stones, sand, cement.
In pre-stress concrete minimum grade of concrete M20.
#Steel:
High tensile steel, tendons, strands.
In pre-stress concrete high tensile steel with tensile strength
around 2000MPa.
According to IS: 1343-1980 prestress concrete is design.
115. Pre-tensioning or Post-tensioning
Pre-tensioning
The tension is applied to the tendons before
casting of the concrete. The pre-compression is
transmitted from steel to concrete through bond
over the transmission length near the ends. The
following figure shows manufactured pre-
tensioned electric poles.
118. Post-tensioning
The tension is applied to the tendons (located
in a duct) after hardening of the concrete. The
pre-compression is transmitted from steel to
concrete by the anchorage device (at the end
blocks). The following figure shows a post-
tensioned box girder of a bridge.
120. SMART MATERIALS
• Smart materials have different properties that
can be changed according to the conditions in
a controlled way by external factors, such as
temperature, light, stress, moisture, electric or
magnetic fields, pH or chemical compounds.
These are also known as intelligent or
responsive materials.
