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.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

3. • Metal cutting operations
– Manually – by using hand tools such as chisels, files etc.
– Machines - machine tools
• Machine tools
– A machine tool may be defined as a power driven machine which
accomplishes the cutting operations
• The fundamental machine tools that are used for most of the machining
operations are lathe, drilling, tapping, milling, grinding machines.
Introduction
4. • Lathe is a machine tool employed generally to produce cylindrical
objects.
• It is said to be mother of all the machine tools.
• Types of lathe
– Engine lathe
– Speed lathe
– Turret lathe
– Capstan lathe
– CNC lathe
LATHE
5. Engine lathe
• Is the most commonly used general purpose lathe used in engineering
workshops
• Principle of working
8. • The bed is the main component of a lathe.
• All the major components are mounted on the lathe bed, like tail
stock, headstock, carriage, etc. Tailstock and carriage move over
the guide ways provided on top face of the bed.
• The bed material should have high compressive strength and high
wear resistance. Cast iron alloyed with nickel chromium forms a
good material for bed.
Bed
9. Headstock
• Headstock is mounted on the left hand side of the lathe bed.
• The head stock accommodates gear box, which helps to vary the
spindle speed. The gear box also transmits the power to other parts like
feed rod and lead screw.
• The chuck or face plate is attached to the spindle which provides
mechanical means clutching and rotating the work piece.
• Head stock is also known as live center
10. Tailstock
• The tailstock is mounted on the right hand side of the lathe bed.
• The function of the tailstock is to support the work piece, and to
accommodate different tools like drill, reaming, boring and tapping, etc.
• The tailstock moves on the guide ways over the bed, to accommodate for
different length of work piece.
• Tailstock is known as dead center.
11. Carriage
• The carriage is mounted on the lathe bed, which slides on the guide
ways of the bed.
• The carriage has various other parts like, cross slide, compound rest,
and tool post.
12. Saddle
• The saddle is mounted on the bed and slides along the
ways.
• The cross slide and tool post are mounted on the saddle.
• The movement of the saddle is parallel along the axis of
the lathe, it is also known as feed.
13. Cross slide
• The cross slide is mounted on the top of the saddle. This moves the
tool at perpendicular to the work piece or machine axis.
• The cross slide can be moved either by rotating the cross slide hand
wheel.
• The perpendicular distance moved by the cross slide is proportional to
the amount of metal removed and it is known as depth of cut.
14. Compound slide
• The compound slide (compound rest) is mounted on the top of the
cross slide.
• Compound slide is used to obtain taper on the work piece.
15. Tool post
• The tool post is mounted on top of the compound slide.
• The tool post holds the tool rigidly.
16. Feed rod
• Feed rod is a long shaft extending from the feed box.
• The power is transmitted from a set of gears from headstock.
• The feed rod is used to move the carriage or cross slide for turning,
boring and facing operations.
17. Lead screw
• The lead screw is a long threaded shaft connected to the headstock.
• The lead screw is used only when thread cutting operation is to be
carried out on the work piece.
• For normal turning operations the lead screw is disengaged.
18. Lathe Operations
Different types of operations that can be carried out
1. Facing
2. Straight Turning
3. Chamfering
4. Knurling
5. Grooving and parting off
6. Drilling
7. Boring
8. Taper turning
9. Thread cutting
19. Facing is the process of removing metal from the end of a work piece
to produce a flat surface.
The work piece rotates about its axis and the facing tool is fed
perpendicular to the axis of lathe.
FACING
20. STRAIGHT TURNING
Turning is the removal of metal from the outer diameter of a rotating
cylindrical work piece.
Turning is used to reduce the diameter of the work piece, usually to a
specified dimension.
21. CHAMFERING
It is a process of creating a slope at the end of the work
piece.
This process is carried out for removing the unwanted
metals and burrs after turning operation.
22. KNURLING
Knurling is the process of embossing a required shaped
pattern on the surface of the work piece.
This diagram shows the knurling tool pressed against a
piece of circular work piece.
23. PARTING
Parting off is the operation of cutting a work piece after it
has been finished to the desired dimension and shape.
In parting operation both feed is fixed or locked and depth
of cut is controlled properly until the work is cut off in
parts.
24. TAPER TURNING
A taper may be defined as a uniform decrease in diameter of work
piece measured along its length.
Taper surface is generated on a cylindrical work piece.
The amount of taper in a work piece is usually specified by the
difference in diameters of the taper to its length.
D-Large diameter of taper in mm.
d- Small diameter of taper in mm.
l- Length of tapered part in mm.
α- Angle of taper or half taper angle.
25. THREAD CUTTING
Thread cutting is the operation of producing helical groove on a
cylindrical surface.
Threads may be square or v threads can be cut on a cylindrical work
piece.
The threads of any pitch, shape and size can be cut on a lathe.
A single point cutting tool (V-tool or square tool) is used to cut threads
on the work piece.
26. For thread cutting operation, the tool is moved automatically in
longitudinal direction.
The longitudinal feed should be equal to the pitch of the thread to be
cut per revolution of the work.
