This document discusses JavaScript events. It defines an event as something that occurs when a user or browser manipulates a web page, like loading the page, clicking a button, or resizing the window. Developers can use events to trigger JavaScript code that responds to these user actions. Common event types discussed include onclick, which occurs when a user clicks an element, onsubmit for form submission, onmouseover/out for mouse movement, and onchange for input field changes. Examples are provided to demonstrate how to attach event handlers to elements to run JavaScript code in response to events.

A JavaScript function is a block of code designed to perform a particular task.
Why Functions?
You can reuse code: Define the code once, and use it many times. You can use the same code many times with different arguments, to produce different results.
JavaScript Events:
HTML events are "things" that happen to HTML elements. When JavaScript is used in HTML pages, JavaScript can "react" on these events.
What can JavaScript Do?
Event handlers can be used to handle, and verify, user input, user actions, and browser actions:
Things that should be done every time a page loads
Things that should be done when the page is closed
Action that should be performed when a user clicks a button
Content that should be verified when a user inputs data

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.

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.

2. What is an Event ?
JavaScript's interaction with HTML is handled through
events that occur when the user or the browser
manipulates a page.
When the page loads, it is called an event. When the
user clicks a button, that click too is an event. Other
examples include events like pressing any key, closing
a window, resizing a window, etc.
3. Cont..
Developers can use these events to execute JavaScript
coded responses, which cause buttons to close
windows, messages to be displayed to users, data to be
validated, and virtually any other type of response
imaginable.
Events are a part of the Document Object Model
(DOM) and every HTML element contains a set of
events which can trigger JavaScript Code.
4. onclick Event Type
This is the most frequently used event type which occurs when a user clicks the left button of his mouse. You can put your
validation, warning etc., against this event type.
<html>
<head>
<script type = "text/javascript">
<!--
function sayHello() {
alert("Hello World")
}
//-->
</script>
</head>
<body>
<p>Click the following button and see result</p>
<form>
<input type = "button" onclick = "sayHello()" value = "Say Hello" />
</form>
</body>
</html>
5. onsubmit Event Type
onsubmit is an event that occurs when you try to
submit a form. You can put your form validation
against this event type.
6. onmouseover and onmouseout
<html>
<head>
<script type = "text/javascript">
<!--
function over() {
document.write ("Mouse Over");
}
function out() {
document.write ("Mouse Out");
}
//-->
</script>
</head>
<body>
<p>Bring your mouse inside the division to see the result:</p>
<div onmouseover = "over()" onmouseout = "out()">
<h2> This is inside the division </h2>
</div>
</body>
</html>
7. Onchange input event
<html>
<head>
<script>
function myFunction() {
var x = document.getElementById("fname");
x.value = x.value.toUpperCase();
}
</script>
</head>
<body>
Enter your name: <input type="text" id="fname" onchange="myFunction()">
<p>When you leave the input field, a function is triggered which transforms the input
text to upper case.</p>
</body>
</html>
