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.

The presentation also covers the positive and negative aspects of inductive bias, along with strategies for mitigating potential drawbacks. We'll explore examples of how bias manifests in algorithms like neural networks and decision trees.
By understanding inductive bias, you can gain valuable insights into how machine learning models work and make informed decisions when building and deploying them.
Harnessing WebAssembly for Real-time Stateless Streaming PipelinesChristina Lin
Traditionally, dealing with real-time data pipelines has involved significant overhead, even for straightforward tasks like data transformation or masking. However, in this talk, we’ll venture into the dynamic realm of WebAssembly (WASM) and discover how it can revolutionize the creation of stateless streaming pipelines within a Kafka (Redpanda) broker. These pipelines are adept at managing low-latency, high-data-volume scenarios.

HEAP SORT ILLUSTRATED WITH HEAPIFY, BUILD HEAP FOR DYNAMIC ARRAYS.
Heap sort is a comparison-based sorting technique based on Binary Heap data structure. It is similar to the selection sort where we first find the minimum element and place the minimum element at the beginning. Repeat the same process for the remaining elements.

2. Introduction
• Present the syntax of Java
• Introduce the Java API
• Demonstrate how to build
– stand-alone Java programs
– Java applets, which run within browsers e.g.
Netscape
• Example programs
3. Why Java?
• It’s the current “hot” language
• It’s almost entirely object-oriented
• It has a vast library of predefined objects
and operations
• It’s more platform independent
– this makes it great for Web programming
• It’s more secure
• It isn’t C++
4. Applets, Servlets and
Applications
• An applet is designed to be embedded in a
Web page, and run by a browser
• Applets run in a sandbox with numerous
restrictions; for example, they can’t read
files and then use the network
• A servlet is designed to be run by a web
server
• An application is a conventional program
5. Building Standalone JAVA
Programs (on UNIX)
• Prepare the file foo.java using an editor
• Invoke the compiler: javac foo.java
• This creates foo.class
• Run the java interpreter: java foo
6. Java Virtual Machine
• The .class files generated by the compiler are
not executable binaries
– so Java combines compilation and interpretation
• Instead, they contain “byte-codes” to be
executed by the Java Virtual Machine
– other languages have done this, e.g. UCSD Pascal
• This approach provides platform
independence, and greater security
7. HelloWorld (standalone)
public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello World!");
}
}
• Note that String is built in
• println is a member function for the
System.out class
8. Comments are almost like C++
• /* This kind of comment can span multiple lines
*/
• // This kind is to the end of the line
• /**
* This kind of comment is a special
* ‘javadoc’ style comment
*/
9. Primitive data types are like C
• Main data types are int, double,
boolean, char
• Also have byte, short, long, float
• boolean has values true and false
• Declarations look like C, for example,
– double x, y;
– int count = 0;
10. Expressions are like C
• Assignment statements mostly look like those in C; you
can use =, +=, *= etc.
• Arithmetic uses the familiar + - * / %
• Java also has ++ and --
• Java has boolean operators && || !
• Java has comparisons < <= == != >= >
• Java does not have pointers or pointer arithmetic
11. Control statements are like C
• if (x < y) smaller = x;
• if (x < y){ smaller=x;sum += x;}
else { smaller = y; sum += y; }
• while (x < y) { y = y - x; }
• do { y = y - x; } while (x < y)
• for (int i = 0; i < max; i++)
sum += i;
• BUT: conditions must be boolean !
12. Control statements II
• Java also introduces the try statement,
about which more later
switch (n + 1) {
case 0: m = n - 1; break;
case 1: m = n + 1;
case 3: m = m * n; break;
default: m = -n; break;
}
13. Java isn't C!
• In C, almost everything is in functions
• In Java, almost everything is in classes
• There is often only one class per file
• There must be only one public class per file
• The file name must be the same as the name
of that public class, but with a .java
extension
14. Java program layout
• A typical Java file looks like:
import java.awt.*;
import java.util.*;
public class SomethingOrOther {
// object definitions go here
. . .
}
This must be in a file named SomethingOrOther.java !
15. What is a class?
• Early languages had only arrays
– all elements had to be of the same type
• Then languages introduced structures (called
records, or structs)
– allowed different data types to be grouped
• Then Abstract Data Types (ADTs) became popular
– grouped operations along with the data
16. So, what is a class?
• A class consists of
– a collection of fields, or variables, very much
like the named fields of a struct
– all the operations (called methods) that can be
performed on those fields
– can be instantiated
• A class describes objects and operations
defined on those objects
17. Name conventions
• Java is case-sensitive; maxval, maxVal, and
MaxVal are three different names
• Class names begin with a capital letter
• All other names begin with a lowercase letter
• Subsequent words are capitalized: theBigOne
• Underscores are not used in names
• These are very strong conventions!
18. The class hierarchy
• Classes are arranged in a hierarchy
• The root, or topmost, class is Object
• Every class but Object has at least one
superclass
• A class may have subclasses
• Each class inherits all the fields and methods
of its (possibly numerous) superclasses
19. An example of a class
class Person {
String name;
int age;
void birthday ( ) {
age++;
System.out.println (name + ' is
now ' + age);
}
}
20. Another example of a class
class Driver extends Person {
long driversLicenseNumber;
Date expirationDate;
}
21. Creating and using an object
• Person john;
john = new Person ( );
john.name = "John Smith";
john.age = 37;
• Person mary = new Person ( );
mary.name = "Mary Brown";
mary.age = 33;
mary.birthday ( );
22. An array is an object
• Person mary = new Person ( );
• int myArray[ ] = new int[5];
– or:
• int myArray[ ] = {1, 4, 9, 16,
25};
• String languages [ ] =
{"Prolog", "Java"};
