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.

6. Milling machine
Milling: is a metal cutting operation in which the
excess material from the work piece is removed by
rotating multipoint cutting tool called milling cutter.
A milling machine is a machine tool that removes
metal as the work is fed against a rotating multipoint
cutter. The milling cutter rotates at high speed and it
removes metal at a very fast rate with the help of
multiple cutting edges.
One or more number of cutters can be mounted
simultaneously on the milling machine. This is the
reason that a milling machine finds wide application in
production work.
Used for machining flat surfaces, contoured surfaces,
external and internal threads.
7. Milling machine
As the workpiece moves against the cutting edges of
milling cutter, metal is removed in form chips
Machined surface is formed in one or more passes
of the work.
The work to be machined is held in a vice, a rotary
table, a three jaw chuck, an index head, in a special
fixture or bolted to machine table.
In many applications, due to its higher production rate
and accuracy, milling machine has even replaced
shapers and slotters.
9. MILLING METHODS
Two basic methods of milling
1.Up-milling or conventional milling
2.Down-milling or climb milling
1.Up-milling or conventional milling
Metal is removed by cutter rotating against the
direction of travel of the workpiece.
Needs stronger holding of the job.
Chip thickness is minimum at the start of cut and
maximum at the end of the cut.
Disadvantage- tendency to lift work from the fixtures
and poor surface finish.
11. MILLING METHODS
2.down-milling or climb milling
Metal is removed by cutter rotating in the same
direction of travel of the workpiece.
teeth cut downward instead of upwards.
Chip thickness is maximum at the start of cut and
minimum at the end of cut.
Less friction involved
Better surface finish.
Less power consumption.
14. TYPES OF MILLING MACHINE
The milling machine may be classified in several
forms, but the choice of any particular machine is
determined primarily by the size of the workpiece.
According to general design, the distinctive types of
milling machines are:
1. Column and knee type milling machines
2. Planer milling machine
3. Fixed-bed type milling machine
4. Special types of milling machines
16. COLUMN AND KNEE TYPE
It is the most commonly used
milling machine used for
general shop work.
The table is mounted on the
knee which in turn is mounted
on the vertical slides of the
main column.
The knee is vertically
adjustable on the column so
that the table can be moved up
and down to accommodate
work of various heights.
17. CLASSIFIACTION OF COLUMN & KNEE
TYPE MILLING MACHINE
(a) Hand milling m/c.
(b) Horizontal milling m/c.
(c) Universal milling m/c.
(d) Vertical milling m/c.
18. (a) Horizontal Milling machine
• The horizontal milling machine has a
spindle that is parallel to the shop floor
and an overarm that extends over the
workpiece.
• The overarm supports the arbor, which
holds the milling cutter.
• On the horizontal mill, the arbor is the
component that rotates the milling cutter.
21. ARBORS
Fig : Mounting a milling cutter on an arbor for use on a horizontal milling machine.
22. (B) VERTICAL MILLING MACHINE
Spindle is vertical or perpendicular to the work table.
It has all the movements of the table for proper setting
and feeding the work.
Spindle head may be swiveled at an angle, permitting the
milling cutter mounted on the spindle to work on angular
surfaces.
In some machines, spindle can also be adjusted up or
down relative to the work.
Adopted for machining grooves, slots and flat surfaces.

26. 2. Fixed-bed type milling machine
•Comparatively large, heavy and rigid and differ from column
and knee type milling machines.
•Table is directly mounted on fixed bed.
•No provision is provided for cross or vertical adjustment of
the table.
•The cutter mounted on the spindle head may be moved
vertically on the column and the spindle may be adjusted
horizontally to provide cross adjustment.
•Three types
1. Simplex 2. duplex 3. triplex
28. 3. PLANER MILLING MACHINE
Looks like double column planer machine.
Milling heads mounted in various planes, vertical heads
on the cross-rail and horizontal heads at the sides (on
column)
This arrangement enables it to machine a workpiece on
several sides simultaneously
Used for producing long straight surfaces on large and
heavy machine parts.
29. 5. SPECIAL-TYPE MACHINES
Designed for individual milling operations
Used for only one particular type of job
Completely automatic Employed when hundreds or
thousands of similar pieces are to be machined
