This document discusses JavaScript arrays. It explains that JavaScript arrays allow storing multiple values in a single variable. There are two ways to declare an array: using array literal syntax (var name = [item1, item2]) or the new keyword (var name = new Array(item1, item2)). The document also demonstrates how to access array elements by index, change array element values, loop through arrays, and output the full array.

JavaScript Arrays
 JavaScript arrays are used to store multiple values in a
single variable.
 Declaration of an Array
There are basically two ways to declare an array.
Example:
 var House = [ ]; // method 1
var House = new array(); // method 2

Example
 <html>
 <body>
 <h2>JavaScript Arrays</h2>
 <p id="demo"></p>
 <script>
 var cars = [“Maruti", “Hundai", "BMW"];
 document.getElementById("demo").innerHTML = cars;
 </script>
 </body>
 </html>
 Output: JavaScript Arrays
 Maruti,Hundai,BMW

Creating an Array
 Using an array literal is the easiest way to create a
JavaScript Array.
 Syntax:
 var array_name = [item1, item2, ...];

Using the JavaScript Keyword new
 The following example also creates an Array, and
assigns values to it:
 <script>
 var cars = new Array(“Maruti", “Hundai", "BMW");
 document.getElementById("demo").innerHTML =
cars;
 </script>

Access the Elements of an Array
 <script>
 var cars = [“Maruti", “Hundai", "BMW"];
 document.getElementById("demo").innerHTML =
cars[0];
 </script>
 Output: Maruti

Changing an Array Element
 <script>
 var l = [“xy", “yz", “zx"];
 l[0] = “ab";
 document.getElementById("demo").innerHTML = I;
 Output: ab, yz, zx

Looping Array Elements
 <script>
 var fruits, text, fLen, i;
 fruits = ["Banana", "Orange", "Apple", "Mango"];
 fLen = fruits.length;
 text = "<ul>";
 for (i = 0; i < fLen; i++) {
 text += "<li>" + fruits[i] + "</li>";
 }
 text += "</ul>";
 document.getElementById("demo").innerHTML = text;
 </script>
 Output:
 Banana
 Orange
 Apple
 Mango

Access the Full Array
 <script>
 var shapes = [“circle", “triangle", “square"];
document.getElementById("demo").innerHTML =
cars;
 </script>
Output: circle, triangle, square

An Overview of HTML, CSS & Java ScriptFahim Abdullah

HTML is a markup language used to define the structure and layout of web pages. It uses tags like <h1> and <p> to mark headings and paragraphs. CSS is used to style and lay out HTML elements, using selectors, declarations, and properties to change things like colors and positioning. JavaScript can be added to HTML pages with <script> tags and is used to add interactive elements and dynamic behavior by manipulating HTML and responding to user input. It has data types like strings and numbers and control structures like if/else statements.

JavaScript - Chapter 11 - Events WebStackAcademy

This document discusses JavaScript events. It defines an event as an action a script can respond to, such as clicks or keystrokes. Event handlers are functions assigned to events that run when the event occurs. Events follow a cycle of capturing, targeting, and bubbling. Common event types include mouse, keyboard, loading, selection, and other events. The document provides examples of using event handlers with buttons, images, and adding/removing event listeners.

Javascript variables and datatypesVarun C M

JavaScript variables hold values and are declared with var. Variable names are case sensitive and must begin with a letter or underscore. Variables can hold numbers, strings, Booleans, objects, and null values. Arrays are objects that hold multiple values in a single variable. Functions are blocks of code that perform tasks and are executed by events or calls. Objects store related data and functions to represent self-contained entities.

JavaScript - Chapter 8 - ObjectsWebStackAcademy

In JavaScript, almost "everything" is an object. -Booleans can be objects (if defined with the new keyword) -Numbers can be objects (if defined with the new keyword) -Strings can be objects (if defined with the new keyword) -Dates are always objects -Maths are always objects -Regular expressions are always objects -Arrays are always objects -Functions are always objects -Objects are always objects

VB ScriptSatish Sukumaran

VBScript is a scripting language launched by Microsoft in 1996 that can be used for client-side and server-side scripting. It supports only one data type called "Variant" that behaves as a number or string depending on context. Variables in VBScript can be declared using keywords like Dim, Public, and Private and follow standard naming conventions. Arrays allow storing multiple values in a single variable. Procedures like Sub and Function can be used to organize code and may accept arguments. Conditional statements like If/Else and Select Case allow choosing between code blocks. Loops like For, For Each, Do While, and Do Until are used to repeat steps. Built-in functions provide useful operations.

Data types in phpilakkiya

This document discusses the different data types in PHP, including integer, floating point, boolean, string, array, object, resource, and null. It provides examples and explanations of each data type. Integer is for whole numbers, floating point for numbers with decimals, boolean for true/false values, string for text values that can be declared with single, double, heredoc, or nowdoc quotes. Array stores multiple values, resource references external functions, and null represents a variable with no value.

Threads in JAVAHaldia Institute of Technology

Threads allow multiple tasks to run concurrently within a single Java program. A thread represents a separate path of execution and threads can be used to improve performance. There are two main ways to create threads: by extending the Thread class or implementing the Runnable interface. Threads transition between different states like new, runnable, running, blocked, and terminated. Synchronization is needed to prevent race conditions when multiple threads access shared resources simultaneously. Deadlocks can occur when threads wait for each other in a circular manner.

Javascript validating formJesus Obenita Jr.

JavaScript can be used to validate form data before submission. It checks that required fields are filled, emails and dates are valid, and text is not entered in numeric fields. Validation functions return false to stop submission if errors are found. For example, a function checks if the first name field is empty and alerts the user, returning false to prevent form submission. This function can be called on form submit using the onsubmit event.

JavaScript is a scripting language that allows dynamic interactivity on web pages. It was invented by Brendan Eich and can be used to create image galleries, layout changes, and button click responses. JavaScript code can be placed between <script> tags in HTML documents or in external .js files. Some key features include client-side execution in web browsers, dynamic rendering variations across browsers, and potential security issues if not implemented carefully. Common uses of JavaScript include manipulating DOM elements, handling events, and validating forms.

29. Treffen - Tobias Meier - TypeScript.NET User Group Rhein-Neckar

Vortrag: Tobias Meier (ca. 90 Minuten) - „TypeScript” JavaScript, früher lediglich zur Anreicherung von Webseiten verwendet, dient inzwischen als Programmiersprache für umfangreiche Applikationen. Allerdings sind viele Entwickler nicht ganz glücklich mit der Sprache und vermissen Features wie statische Typprüfungen oder Vererbung. Auch die großen Konzerne haben mit diesen “Herausforderungen” zu kämpfen. Im Oktober 2012 hat Anders Hejlsberg, (Mit-)Erfinder von Delphi und .Net, TypeScript vorgestellt. Bei TypeScript handelt es sich um ein Superset von JavaScript, welches dieses um Klassen, Module, Interfaces, Datentypen u.ä. ergänzt. Inzwischen hat auch das AngularJS-Team bekanntgegeben dass sie zukünftig auf TypeScript aufsetzen. Tobias Meier stellt die aktuelle Version von TypeScript vor und zeigt, wie TypeScript uns sowohl bei der Entwicklung von Singe Page Applications als auch herkömmlichen Webapplikationen unterstützt. Tobias Meier ist Lead Softwarearchitekt Microsoft bei der BridgingIT GmbH und setzt TypeScript bereits seit der ersten verfügbaren Preview erfolgreich in Kundenprojekten ein.

Gray level transformationchauhankapil

Linear gray level transformations include identity and negative transformations. Identity transformation directly maps each pixel value from the input image to the output image, resulting in identical images. Negative transformation inverts each pixel value by subtracting it from the maximum value L-1, effectively inverting the pixel values of the input image. Linear transformations were described along with examples of identity and negative transformations.

Elements of visual perceptionchauhankapil

This document discusses elements of visual perception and image processing. It defines an image as a two-dimensional function where x and y are spatial coordinates and amplitude is intensity. A digital image is composed of pixels with locations and values. Image processing includes importing images, analyzing and manipulating them, and outputting results. Visual perception is based on mathematical formulations, with human judgment selecting techniques. The eyes act as sensors, neurons connect to the brain which processes images. Elements of visual perception include eye structure, image formation in the eye, and brightness adaptation and discrimination.

Markov decision processchauhankapil

Markov Decision Process (MDP) is a reinforcement learning model that consists of: (1) states, (2) actions, (3) transition models, and (4) rewards. The goal is to find the optimal policy, which maps states to the best actions, in order to maximize long-term rewards. In an MDP, an agent takes an action in a state, then transitions to a new state based on the transition model, and receives an immediate reward.

RNN basics in deep learningchauhankapil

Recurrent neural networks (RNNs) are a type of neural network that can handle sequential data by saving the output of each layer and feeding it back as input. RNNs were created to address issues with feed-forward neural networks, which cannot handle sequential data, only consider the current input, and cannot memorize previous inputs. RNNs have applications in areas like image captioning, time series prediction, natural language processing, and machine translation.

Introduction to generative adversarial networks (GANs)chauhankapil

Generative adversarial networks (GANs) are a type of deep learning model used for generative modeling. GANs involve training two neural networks - a generator and a discriminator. The generator produces synthetic data while the discriminator evaluates it as real or fake. This adversarial process trains the generator to produce increasingly realistic samples. GANs frame generative modeling as an adversarial game to learn the training data distribution in an unsupervised manner.

Bayesian probabilistic interferencechauhankapil

This document discusses Bayesian networks, which use a directed acyclic graph structure to represent conditional independence relationships between variables and compactly specify joint probability distributions. An example Bayesian network is given showing how the topology encodes that weather is independent of other variables and that toothache and catching a cold are conditionally independent given having a cavity. Reasons for using and learning Bayesian networks are explained, including that they provide an intuitive way to incorporate causal knowledge and allow for efficient inference queries.

Jspchauhankapil

Java Server Pages (JSP) is a technology that provides a simplified and fast way to create web pages that display dynamically generated content. A JSP page combines static HTML tags with JSP tags that insert Java code. This allows developers to add dynamic functionality to web pages by embedding Java code directly in the HTML. A simple JSP page example prints the current time by embedding a Java statement between <% %> tags in the HTML. JSP pages are translated into Java servlets, so they benefit from the full capabilities of the Java programming language.

Knowledge acquistionchauhankapil

The document discusses knowledge acquisition for artificial intelligence. It defines knowledge acquisition as the process used to define rules and syntax for knowledge-based systems. It also discusses different types of knowledge, including declarative knowledge (knowing facts), procedural knowledge (knowing how to do something), meta knowledge (knowing about other types of knowledge), heuristic knowledge (rules of thumb from experience), and structural knowledge (relationships between concepts). The document provides examples and definitions for each type of knowledge.

Knowledge based systemchauhankapil

The document discusses knowledge based systems, which use artificial intelligence to solve problems that normally require human expertise by drawing on knowledge captured in a knowledge base. It explains that knowledge based systems typically use rule-based or case-based reasoning and can be used for tasks like classification, diagnosis and planning. The document also outlines the typical components of a knowledge based system like the knowledge base, inference engine and interface, as well as approaches to knowledge representation.

Introduction of predicate logicschauhankapil

This document introduces predicate logic and its key concepts. It discusses that predicate logic uses predicate symbols to represent relations between objects, with the number of objects defining a predicate's degree. Predicate logic formulas can be joined using logical connectives like negation, conjunction, disjunction, and implication. Quantifiers like universal and existential are used to express properties of object collections. The syntax of predicate logic is inspired by Prolog and uses terms formed from constants, variables, and function symbols, along with quantifiers and sentences. Some useful equivalences for eliminating and distributing quantifiers are also presented. The document concludes by assigning students to describe predicate logic and discuss useful formulas for designing facts.

Types of inheritance in javachauhankapil

There are three types of inheritance in Java: single, multilevel, and hierarchical. Single inheritance allows a child class to inherit from one parent class, as in the example of the Dog class extending the Animal class. Multilevel inheritance allows a grandchild class to inherit from a parent class through a child class, as in the BabyDog class extending Dog and indirectly inheriting from Animal. Hierarchical inheritance allows multiple child classes to inherit from a common parent class, as in both the Dog and Cat classes extending Animal.

Representation of syntax, semantics and Predicate logicschauhankapil

This document discusses different methods for representing syntax, semantics, and predicate logic in natural language processing. It introduces propositional and formal semantics which represent text as logical formulas, as well as vector representations which embed text in multi-dimensional space. Various logical representations are examined including propositional logic, predicate logic, production rules, semantic networks, and description logics.

Inheritance in javachauhankapil

This document discusses inheritance in Java. It defines key terms like subclass, superclass, and reusability. It explains that a subclass inherits the properties and behaviors of its parent superclass. The syntax for inheritance in Java uses the "extends" keyword. The document provides two code examples to demonstrate inheritance - a Programmer subclass that inherits from an Employee superclass, and a My_Calculation subclass that inherits and extends the Calculation superclass with a new method.

Propositional logicchauhankapil

Propositional logic is the simplest form of logic that uses propositions that are either true or false. A proposition is a declarative statement. Propositional logic represents knowledge using symbolic variables and logical connectors. There are two types of propositions: atomic propositions which are single statements, and compound propositions which combine simpler propositions using logical connectors like AND and OR. Propositional logic is also known as Boolean logic as it uses 1s and 0s to represent true and false values.

Constructors in javachauhankapil

Constructors in Java are special methods that are used to initialize objects. There are two types of constructors: default (no-arg) constructors that take no parameters, and parameterized constructors that allow passing parameters to initialize an object. Constructors must have the same name as the class and cannot have a return type. They are automatically called when an object is created using the new keyword to allocate memory and initialize fields.

Methods in javachauhankapil

This document discusses methods in Java. It defines a method as a collection of instructions that performs a specific task and provides code reusability. There are two types of methods in Java: predefined methods and user-defined methods. Predefined methods are methods already defined in Java class libraries that can be directly called, while user-defined methods are written by programmers according to their needs. Examples of both types of methods are provided.

Circular linked listchauhankapil

This document provides an introduction to circular linked lists. It explains that a circular linked list is a variation of a linked list where the first element points to the last element, forming a loop. Both singly and doubly linked lists can be made circular by having the next pointer of the last node point to the first node, and in doubly linked lists the previous pointer of the first node points to the last node. Basic operations like insert, delete, and display are supported. Memory management involves the head pointer storing the address of the first node, and each node storing the address of the next node and last node.

Modelling of Concrete Compressive Strength Admixed with GGBFS Using Gene Expr...Journal of Soft Computing in Civil Engineering

Several studies have established that strength development in concrete is not only determined by the water/binder ratio, but it is also affected by the presence of other ingredients. With the increase in the number of concrete ingredients from the conventional four materials by addition of various types of admixtures (agricultural wastes, chemical, mineral and biological) to achieve a desired property, modelling its behavior has become more complex and challenging. Presented in this work is the possibility of adopting the Gene Expression Programming (GEP) algorithm to predict the compressive strength of concrete admixed with Ground Granulated Blast Furnace Slag (GGBFS) as Supplementary Cementitious Materials (SCMs). A set of data with satisfactory experimental results were obtained from literatures for the study. Result from the GEP algorithm was compared with that from stepwise regression analysis in order to appreciate the accuracy of GEP algorithm as compared to other data analysis program. With R-Square value and MSE of -0.94 and 5.15 respectively, The GEP algorithm proves to be more accurate in the modelling of concrete compressive strength.

Dynamics of Structures with Uncertain Properties.pptxUniversity of Glasgow

In modern aerospace engineering, uncertainty is not an inconvenience — it is a defining feature. Lightweight structures, composite materials, and tight performance margins demand a deeper understanding of how variability in material properties, geometry, and boundary conditions affects dynamic response. This keynote presentation tackles the grand challenge: how can we model, quantify, and interpret uncertainty in structural dynamics while preserving physical insight? This talk reflects over two decades of research at the intersection of structural mechanics, stochastic modelling, and computational dynamics. Rather than adopting black-box probabilistic methods that obscure interpretation, the approaches outlined here are rooted in engineering-first thinking — anchored in modal analysis, physical realism, and practical implementation within standard finite element frameworks. The talk is structured around three major pillars: 1. Parametric Uncertainty via Random Eigenvalue Problems * Analytical and asymptotic methods are introduced to compute statistics of natural frequencies and mode shapes. * Key insight: eigenvalue sensitivity depends on spectral gaps — a critical factor for systems with clustered modes (e.g., turbine blades, panels). 2. Parametric Uncertainty in Dynamic Response using Modal Projection * Spectral function-based representations are presented as a frequency-adaptive alternative to classical stochastic expansions. * Efficient Galerkin projection techniques handle high-dimensional random fields while retaining mode-wise physical meaning. 3. Nonparametric Uncertainty using Random Matrix Theory * When system parameters are unknown or unmeasurable, Wishart-distributed random matrices offer a principled way to encode uncertainty. * A reduced-order implementation connects this theory to real-world systems — including experimental validations with vibrating plates and large-scale aerospace structures. Across all topics, the focus is on reduced computational cost, physical interpretability, and direct applicability to aerospace problems. The final section outlines current integration with FE tools (e.g., ANSYS, NASTRAN) and ongoing research into nonlinear extensions, digital twin frameworks, and uncertainty-informed design. Whether you're a researcher, simulation engineer, or design analyst, this presentation offers a cohesive, physics-based roadmap to quantify what we don't know — and to do so responsibly.

Prediction of Flexural Strength of Concrete Produced by Using Pozzolanic Mate...Journal of Soft Computing in Civil Engineering

The use of huge quantity of natural fine aggregate (NFA) and cement in civil construction work which have given rise to various ecological problems. The industrial waste like Blast furnace slag (GGBFS), fly ash, metakaolin, silica fume can be used as partly replacement for cement and manufactured sand obtained from crusher, was partly used as fine aggregate. In this work, MATLAB software model is developed using neural network toolbox to predict the flexural strength of concrete made by using pozzolanic materials and partly replacing natural fine aggregate (NFA) by Manufactured sand (MS). Flexural strength was experimentally calculated by casting beams specimens and results obtained from experiment were used to develop the artificial neural network (ANN) model. Total 131 results values were used to modeling formation and from that 30% data record was used for testing purpose and 70% data record was used for training purpose. 25 input materials properties were used to find the 28 days flexural strength of concrete obtained from partly replacing cement with pozzolans and partly replacing natural fine aggregate (NFA) by manufactured sand (MS). The results obtained from ANN model provides very strong accuracy to predict flexural strength of concrete obtained from partly replacing cement with pozzolans and natural fine aggregate (NFA) by manufactured sand.

Java script array

1. JavaScript Arrays Prof. Neeraj Bhargava Kapil Chauhan Department of Computer Science School of Engineering & Systems Sciences MDS University, Ajmer

2. JavaScript Arrays  JavaScript arrays are used to store multiple values in a single variable.  Declaration of an Array There are basically two ways to declare an array. Example:  var House = [ ]; // method 1 var House = new array(); // method 2

3. Example  <html>  <body>  <h2>JavaScript Arrays</h2>  <p id="demo"></p>  <script>  var cars = [“Maruti", “Hundai", "BMW"];  document.getElementById("demo").innerHTML = cars;  </script>  </body>  </html>  Output: JavaScript Arrays  Maruti,Hundai,BMW

4. Creating an Array  Using an array literal is the easiest way to create a JavaScript Array.  Syntax:  var array_name = [item1, item2, ...];

5. Using the JavaScript Keyword new  The following example also creates an Array, and assigns values to it:  <script>  var cars = new Array(“Maruti", “Hundai", "BMW");  document.getElementById("demo").innerHTML = cars;  </script>

6. Access the Elements of an Array  <script>  var cars = [“Maruti", “Hundai", "BMW"];  document.getElementById("demo").innerHTML = cars[0];  </script>  Output: Maruti

7. Changing an Array Element  <script>  var l = [“xy", “yz", “zx"];  l[0] = “ab";  document.getElementById("demo").innerHTML = I;  Output: ab, yz, zx

8. Looping Array Elements  <script>  var fruits, text, fLen, i;  fruits = ["Banana", "Orange", "Apple", "Mango"];  fLen = fruits.length;  text = "<ul>";  for (i = 0; i < fLen; i++) {  text += "<li>" + fruits[i] + "</li>";  }  text += "</ul>";  document.getElementById("demo").innerHTML = text;  </script>  Output:  Banana  Orange  Apple  Mango

9. Access the Full Array  <script>  var shapes = [“circle", “triangle", “square"]; document.getElementById("demo").innerHTML = cars;  </script> Output: circle, triangle, square
