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.
NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.

2. • Learning any imperative programming language
involves mastering a number of common concepts:
• Variables: Declaration/definition
• Assignment: Assigning values to variables
• Input/Output: Displaying messages/displaying variable values
• Control flow: Loops, JUMPs
• Subprograms: Definition and Usage
Programming in assembly language involves mastering
the same concepts and a few other issues.
3. Variables
• Here we will simply use the 8086 registers as
the variables in our programs.
• Registers have predefined names and do not
need to be declared.
4. Assignment
• In programming languages such as C/C++/Java,
assignment takes the form:
• x = 42 ;
• y = 24;
• z = x + y;
• In assembly language we carry out the same operation
but we use an instruction to denote the assignment
operator (“=”). The above assignments would be
carried out in 8086 assembly langauge as follows:
• Mov ax, 42
• Add ax, 24
• Mov bx,cx
5. • The mov instruction carries out assignment.
• It allows us place a number in a register or in a
memory location (a variable) i.e. it assigns a
value to a register or a variable.
Example:
• mov bx, ‘A’ To store the ASCII code for the
letter A in register bx.
• mov bx, 2 Loads the value 2 in to bx
6. Input/Output
• The 8086 provides the instructions IN for input
and OUT for output.
• These instructions are quite complicated to use,
so we usually use the operating system to do I/O
for us instead.
• In assembly language we must have a mechanism
to call the operating system to carry out I/O.
• In addition we must be able to tell the operating
system what kind of I/O operation we wish to
carry out, e.g. to read a character from the
keyboard, to display a character or string on the
screen, etc…...
7. • In 8086 assembly language, we do not call operating
system subprograms by name, instead, we use a
software interrupt mechanism
• The 8086 INT instruction generates a software interrupt.
• It uses a single operand which is a number indicating
which MS-DOS subprogram is to be invoked.
• For I/O, the number used is 21h. Thus, the instruction
INT 21h transfers control to the operating system, to a
subprogram that handles I/O operations.
• This subprogram handles a variety of I/O operations by
calling appropriate subprograms.
• This means that you must also specify which I/O
operation (e.g. read a character, display a character)
you wish to carry out. This is done by placing a specific
number in a specific register.
8. • The ah register is used to pass this information.
• For example, the subprogram to display a
character is subprogram number 2h.
• This number must be stored in the ah register.
• When the I/O operation is finished, the
interrupt service program terminates and our
program will be resumed.
9. Character Output
• There are three elements involved in carrying out this
operation using the INT instruction:
• We specify the character to be displayed. This is done by
storing the character’s ASCII code in a specific 8086
register. In this case we use the dl register, i.e. we use dl to
pass a parameter to the output subprogram.
• We specify which of MS-DOS’s I/O subprograms we wish to
use. The subprogram to display a character is subprogram
number 2h. This number is stored in the ah register.
• We request MS-DOS to carry out the I/O operation using
the INT instruction. This means that we interrupt our
program and transfer control to the MS-DOS subprogram
that we have specified using the ah register.
10. • Example : Write a code fragment to display
the character ’a’ on the screen:
mov dl, ‘a’ ; dl = ‘a‘
mov ah, 2h ; character output subprogram
int 21h ; call ms-dos, output character
11. Character Input
• There are also three elements involved in
performing character input:
• As for character output, we specify which of MS-
DOS’s I/O subprograms we wish to use, i.e. the
character input from the keyboard subprogram. This
is MS-DOS subprogram number 1h. This number
must be stored in the ah register.
• We call MS-DOS to carry out the I/O operation using
the INT instruction as for character output.
• The MS-DOS subprogram uses the al register to
store the character it reads from the keyboard.
12. • Example: Write a code fragment to read a
character from the keyboard
mov ah, 1h ; keyboard input subprogram
int 21h ; character input
; character is stored in al
13. • Example: Reading and displaying a character:
mov ah, 1h ; keyboard input subprogram
int 21h ; read character into al
mov dl, al ; copy character to dl
mov ah, 2h ; character output subprogram
int 21h ; display character in dl
14. A Complete 8086 Program
(Using Borland Turbo Assembler)
• Use an editor (notepad) to enter the program into a
file. We use Borland’s TASM and TLINK commands for
assembling and linking 8086 assembly language
programs. TASM program files should have names with
the extension (3 characters after period) asm.
• Let we will call our first program prog1.asm (You may
use any name you wish. It is a good practice to choose
a meaningful file name), which displays the letter ‘a’ on
the screen. Having entered and saved the program
using an editor, you must then use the TASM and TLINK
commands to translate it to machine code in the
command prompt.
15. Program 1:
• A complete program to display the letter ‘a’ on the screen:
16. • To translate the program to machine code and then go for execution,
C:> tasm prog1.asm
• If you have syntax errors, you will get error messages at this point. You then
have to edit your program, correct them and repeat the above command.
C:> tlink prog1
• To execute the program, simply enter the program name and press the Return
key:
C:> prog1
• The output of the above program will be in the screen as below:
a
C:>
17.
18. • When a program has finished, we return to the
operating system.
• Like carrying out an I/O operation, this is also
accomplished by using the INT instruction. This
time MS-DOS subprogram number 4c00h is
used.
• It is the subprogram to terminate a program
and return to MS-DOS. Hence, the instructions:
mov ax, 4c00h ; Code for return to MS-DOS
int 21H ; Terminates program and return to MS-DOS.
• is a must to terminate a program code, otherwise the program
may crash
19. Program 2:
• Write a program to load character ’?’ into register ax and
display the same on the screen.
20. Program 3:
• A program to print a string ‘My First Assembly Language Program’ on the screen
21. • The above program can be rewritten using the
instruction LEA as follows;
27. • Program 6: Program to add any two hexa decimal numbers
• Program 7: Addition of any two packed BCD numbers.
• Program 8: Program to subtract packed bcd numbers
• Program 9: Program to multiply 2 numbers
• Program 10: Program to divide a packed bcd number.
• Program 11: A program to list numbers from 0,......., 9 (Illustration of Loop )
• Program 12: Program to add consecutive 10 numbers
• Program 13: Program to add any 10 stored numbers
• Program 14: Program to add any 3 numbers, entered through the
keyboard (User interactive)
• Program 15: A program that prompts the user with the question
‘Is it after 12 noon (Y/N)?’ . If the response is ‘y’ for yes , greet the
user with the message 'Good afternoon, world!’, if the response is
‘n’ for No , greet the user with the message 'Good morning,
world!’,else greet with the default message 'Good day, world!’ in a
newline. [This program will make use of ‘cmp’, ‘jmp’ instructions]
29. Things to remember while writing the assignment
