Queue is an abstract data structure, somewhat similar to Stacks. Unlike stacks, a queue is open at both its ends. One end is always used to insert data (enqueue) and the other is used to remove data (dequeue). Queue follows First-In-First-Out methodology, i.e., the data item stored first will be accessed first.
An ordered collection of items from which items may be deleted from one end called the front and into which items may be inserted from other end called rear is known as Queue.
It is a linear data structure.
It is called the First In First Out (FIFO) list. Since in queue, the first element will be the first element out.

Queues and stacks are dynamic while arrays are static. So when we require dynamic memory we use queue or stack over arrays. Stacks and queues are used over arrays when sequential access is required. To efficiently remove any data from the start (queue) or the end (stack) of a data structure
Queue is a Linear list which has two ends, one for insertion of elements and other for deletion of elements. The first end is called 'Rear' and the later is called 'Front'. Elements are inserted from Rear End and Deleted from Front End. Queues are called First In First Out (FIFO) List, since the first element in a queue will be the first element out of the queue. In other words, the order in which the elements enter a queue is the order in which they leave.
In Batch Processing the jobs are "Queued up" as they are read in and executed, one after another in the order they were received. This ignores the possible existence of priorities.

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.

Automobile Management System Project Report.pdfKamal Acharya
The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.

This theory provides a method to calculate the ultimate bearing capacity of soil, which is the maximum load per unit area that the soil can support without undergoing shear failure. The Calculation HTML Code included.
Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.
2. Introduction
A queue is a particular kind of abstract data type or collection in which the entities in the collection are kept in order and the
principal (or only) operations on the collection are the addition (insertion) of entities to the rear terminal position, known
as enqueue, and removal (deletion) of entities from the front terminal position, known as dequeue.
This makes the queue a First-In-First-Out (FIFO) or a First-Come-First-Served (FCFS) data structure. In a FIFO data structure, the
first element added to the queue will be the first one to be removed.
Examples
A checkout line at supermarket cash counter, cashier counter in a bank, ticket counter for fare, etc. The first person in the line is
(usually) the first to be checked out.
Another example is of printing documents. The document given first for printing will be printed first & other documents will
follow the sequence.
3. Representation of Queue
When queue is empty
FRONT = -1 and REAR = -1
Adding an element in queue will increased value of REAR by 1
REAR = REAR + 1
Removing an element from queue will increased value of FRONT by 1
FRONT = FRONT + 1
The vector is assumed to consist of a large number of elements, enough to be sufficient to handle the variable length
property of queue.
The vector representation of a queue requires pointers F & R which denote the positions of its front & rear elements
respectively.
Operations of Queue
4. Types of Queue
Linear (Simple) Queue
Circular Queue
Double-ended Queue (Deque)
Priority Queue
1. Linear (Simple) Queue
5. Insert Operation
Function: LQINSERT (Q,F,R,N,Y). Given F & R, pointers
to the front and rear elements of a queue, a vector Q
consisting of N elements and an element Y, this
procedure inserts Y at the rear of the queue.
Set F=R=-1, when queue is empty.
Algorithm
Step-1: [Check overflow?]
if R>=N-1
then Write (‘Overflow’)
Return
Step-2: [Increment rear pointer R]
R R + 1
Step-3: [Insert element]
Q[R] Y
Step-4: [Set front pointer F]
if F=-1
then F 0
Return
Delete Operation
Function: LQDELETE (Q,F,R). Given F & R, pointers to the front and
rear elements of a queue, a queue Q consisting to which they
correspond, this function deletes and returns the last element of the
queue. Y is a temporary variable.
Algorithm
Step-1: [Check underflow?]
if F=-1
then Write (‘Underflow’)
Return
Step-2: [Delete element]
Y Q[F]
Step-3: [Check for queue empty or has an element?]
if F=R
then F=R=-1
else
F F + 1
Step-4: [Return element]
Return(Y)
7. 2. Circular Queue
In circular queue, all the elements are arranged in a circular form.
Here, the left spaces can be reutilized to insert new variables which was not the case with linear queue.
8. Insert Operation
Function: CQINSERT (Q,F,R,N,Y). Given F & R, pointers
to the front and rear elements of a queue, a vector Q
consisting of N elements and an element Y, this
procedure inserts Y at the rear of the queue.
Set F=R=-1, when queue is empty.
Algorithm
Step-1: [Reset rear pointer R]
if R>=N-1
then R 0
else R R + 1
Step-2: [Check overflow?]
if F=R
then Write (‘Overflow’)
Return
Step-3: [Insert element]
Q[R] Y
Step-4: [Set front pointer F]
if F=-1, then F 0
Return
Delete Operation
Function: CQDELETE (Q,F,R). Given F & R, pointers to the front and
rear elements of a queue, a queue Q consisting to which they
correspond, this function deletes and returns the last element of the
queue. Y is a temporary variable.
Algorithm
Step-1: [Check underflow?]
if F=-1
then Write (‘Underflow’)
Step-2: [Delete element]
Y Q[F]
Step-3: [Check for queue empty or has an element?]
if F=R
then F=R=-1
Return(Y)
Step-4: [Increment front pointer F]
if F=N-1
then F 0,
else F F + 1
Return(Y)
10. 3. Double-ended Queue (Deque)
A deque (double-ended queue) is a linear list in which insertions and deletions are made to or from either
end of the structure.
It is clear that deque is more general than a stack or a queue.
There are two variations of a deque, namely, the input-restricted deque and the output-restricted deque.
The input-restricted deque allows insertions at only one end, while an output-restricted deque permits
deletions from only one end.
12. 4. Priority Queue
A priority queue is collection of elements where elements are stored according to the their priority levels.
Inserting and removing of elements from queue is decided by the priority of the elements.
In a priority queue, an element with high priority is served before an element with low priority.
If two elements have the same priority, they are served according to their order in the queue.
The two fundamental methods of a priority queue P:
insertItem(k,e): Insert an element e with key k into P.
removeMin(): Return and remove from P an element with the smallest key.
