C and C++ are procedural and object-oriented programming languages respectively. C++ was created as an incremental improvement to C by adding object-oriented features while maintaining compatibility with C. Key differences include C++ supporting features like function overloading, polymorphism, encapsulation, and inheritance which are not possible in C. Additionally, C++ emphasizes data abstraction and limits data access compared to the open data model of C where data can be accessed by any function.

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.

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.

Oosd lecture unit 4 ppt introduction part
1. OVERVIEW OF C LANGUAGE:
1.C language is known as structure oriented language or procedure oriented language
2.Employs top-down programming approach where a problem is viewed as a sequence of tasks to
be performed.
3.All program code of c can be executed in C++ but converse many not be possible
4. Function overloading Polymorphism, encapsulation, inheritance and operator overloading are not
possible.
5. Local variables can be declared only at the beginning of the block.
6. Program controls are through jumps and calls to subroutines.
7.For solving the problems, the problem is divided into a number of modules. Each module is a
subprogram.
8. Data abstraction property is not supported by procedure oriented language.
9. Data in procedure oriented language is open and can be accessed by any function.
2. OVERVIEW OF C++ LANGUAGE:
1. C++ can be considered as an incremental version of c language which consists all programming
language constructs with newly added features of object oriented programming.
2. C++ is object oriented programming language.
3. The file extension of C++ program is “.CPP”
4. Function overloading, Polymorphism, encapsulation, inheritance and operator overloading are
possible.
5. Variables can be declared in inline i.e. when required
6. In c++ more emphasis is give on data rather than procedures.
7. Data abstraction property is supported by c++.
8. Data access is limited. It can be accessed by providing various visibility modes both for data and
member functions.
9. Dynamic binding is supported by C++
5. BASIC STRUCTURE OF C++ LANGUAGE:
A C++ program should have one or more sections but the sequence of sections is
to be followed.
1. Documentation section
2. Linking section
3. Definition section
4. Global declaration section & class declarations
5. Member function definition
6. Main function
6. 1. DOCUMENTATION SECTION :
1. Document section comes first and is used to document the use of logic or
reasons in your program.
2. It can be used to write the program's objective, developer and logic
details.
3. The documentation is done in C++ language with /* and */ . Whatever is
written between these two are called comments.
7. 2. LINKING SECTION :
1. This section tells the compiler to link the certain occurrences of keywords or functions
in your program to the header files specified in this section.
2. e.g. #include<iostream>
using namespace std;
3. Directive causes the preprocessor to add the contents of the iostream file to the
program. It contains declarations for cout and cin.
4. cout is a predefined object that represents the standard output stream. The operator
<< is an insertion operator, causes the string in double quotes to be displayed on the
screen.
5. The identifier cin is a predefined object in C++ that corresponds to the standard input
stream. The operator >> is known as extraction operator. It extracts the value from the
keyboard and assigns it to the value variable on its right.
8. 3. DEFINITION SECTION :
1. It is used to declare some constants and assign them some value. e.g.
#define MAX 25
2. Here #define is a compiler directive which tells the compiler whenever MAX is
found in the program replace it with 25.
9. 4. GLOBAL DECLARATION SECTION :
1. Here the variables and class definitions which are used throughout the
program (including main and other functions) are declared to make them global
(i.e
accessible to all parts of program).
2. A CLASS is a collection of data and functions that act or manipulate
the data. The data components of a class are called data members and
function components of a class are called member functions.
3. A class can also termed as a blue print or prototype that defines the variable or
functions common to all objects of certain kind.
4. It is a user defined data type.
5. e.g. int i; //this declaration is done outside and before main()
10. 5. SUB PROGRAM OR FUNCTION SECTION :
This has all the sub programs or the functions which our
program needs.
void display()
{
cout<<”C++ is better that C”;
}
11. 6. MAIN FUNCTION SECTION :
It tells the compiler where to start the execution.
main()
{
point from execution starts
}
main function has two sections
1. declaration section : In this the variables and their data types are
declared.
2. Executable section or instruction section : This has the part of
program which actually performs the task we need.
Editor's Notes
The iostream header file provides functionality for input and output
The std namespace contains many C++ standard library functions and objects, including those for input and output operations. in C++.
Without "using namespace std," you would need to prefix every element from the standard library with std:: to indicate that it comes from the standard namespace.t and output operations in C++.
Declares two variables num1 and num2 to store the two numbers.
Asks the user to enter the first number and stores it in num1.
Asks the user to enter the second number and stores it in num2.
Calculates the sum of num1 and num2 and stores it in the variable sum.
