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.
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.

10. JVM
JVM is platform dependent
The java Virtual Machine provides a platform
–independent way of executing code
Java Virtual Machine Interprets the bytecode
Into machine code depending upon the
underlying operating system and hardware
combination
11. First Program JAVA
Remember
• Java is a case sensitive language like c and c++
• Java is nearly 100% object oriented language
• In java, it is possible to make a function which
is not a member of any class(as we can do in c
and C++)
12. First Program
Public class HelloWorld
{
public static void main(String args[])
{
System.out.println(“HelloWOrld”);
}
}
13. FOR pratical
• Write a program in notepad and save in bin
folder of jdk Compile and run the program
Delete the file from bin folder and make another
program in notepad and save in Desktop and
compile and run the program and please note
the error u got and how u solve the error
14. DataTypes and Keywords In java
Java Identifiers
All the java components require names.Names used for
classes, variables and method are called identifiers.In java ,
there are several points to remember about identifiers.
• All identifiers should begin with a letter (A to Z or a to z),
currency character ($) or an underscore (_).
• After the first character, identifiers can have any combination
of characters.
• A keyword cannot be used as an identifier.
• Most importantly identifiers are case sensitive.
• Examples of legal identifiers:age, $salary, _value, __1_value
• Examples of illegal identifiers: 123abc, -salary
15. Java Keywords
• These reserved words may not be used as constant or variable or any other identifier
names.
17. Literals, Comments,Separators
Literals
A literal is a source code representation of a fixed value. They are
represented directly in the code without any computation.
Comments
Java supports single-line and multi-line comments very similar to c and
c++. All characters available inside any comment are ignored by Java
compiler.
/* This is my first java program.
This will print 'Hello World' as the output
This is an example of multi-line comments. */
// This is an example of single line comment /* This is also an example of
single line comment. */
20. Details about Literals
Literals can be assigned to any primitive type variable. For example:
byte a =68;
char a ='A'
byte, int, long, and short can be expressed in decimal(
base 10),hexadecimal(base 16) or octal(base 8) number systems as well.
Prefix 0 is used to indicate octal and prefix 0x indicates hexadecimal when
using these number systems for literals. For example:
int decimal=100;
int octal =0144;
int hexa =0x64;
String literals in Java are specified like they are in most other languages by
enclosing a sequence of characters between a pair of double quotes.
String and char types of literals can contain any Unicode characters. For
example:
char a ='u0001'; String a ="u0001";
21. Variable
• In Java, all variables must be declared before they
can be used. The basic form of a variable
declaration is shown here:
type identifier [= value][, identifier [= value]...];
int a, b, c;// declares three ints, a, b, and c.
int d =3, e, f =5;// declares three more ints,
initializing // d and f.
byte z =22;// initializes z.
double pi =3.14159;// declares an approximation of
pi.
char x ='x';// the variable x has the value 'x'.
22. • This chapter will explain various variable types
available in Java Language. There are three
kinds of variables in Java:
• Local variables
• Instance variables
• Class/static variables
24. ARRAY
• Declaring Array Variables:
To use an array in a program, you must declare a variable to
reference the array, and you must specify the type of array the variable
can reference. Here is the syntax for declaring an array variable:
dataType[] arrayRefVar; // preferred way.
or
dataType arrayRefVar[]; // works but not preferred way.
Example:
• The following code snippets are examples of this syntax:
double[] myList; // preferred way.
or
• double myList[]; // works but not preferred way.
25. Creating ARRAY
• You can create an array by using the new operator with the following
syntax:
• arrayRefVar = new dataType[arraySize];
• The above statement does two things:
• It creates an array using new dataType[arraySize];
• It assigns the reference of the newly created array to the variable
arrayRefVar.
• Declaring an array variable, creating an array, and assigning the reference
of the array to the variable can be combined in one statement, as shown
below:
• dataType[] arrayRefVar = new dataType[arraySize];
• Alternatively you can create arrays as follows:
• dataType[] arrayRefVar = {value0, value1, ..., valuek};
• The array elements are accessed through the index. Array indices are 0-
based; that is, they start from 0 to arrayRefVar.length-1.
26. • Following statement declares an array variable, myList,
creates an array of 10 elements of double type and assigns its
reference to myList:
• double[] myList = new double[10];
• Following picture represents array myList. Here, myList holds
ten double values and the indices are from 0 to 9.
27. The foreach Loops:
• JDK 1.5 introduced a new for loop known as
foreach loop or enhanced for loop, which
enables you to traverse the complete array
sequentially without using an index variable.
• SCANNER OBJECT
28. PRACTICAL
• TypeCasting Problem
• Declare an array whose size is 5 .Process the
array and Print all the elements of array and
find total sum of all elements and Find
greatest number from that element
• Implement foreach Loop
• Create a class , take the two input from
keyboard and sum two number and process
the array by using Scanner
