React Native is an open source framework for building mobile apps using React and JavaScript. It uses native components and allows building real mobile apps for Android and iOS. It works by using a virtual DOM layer that maps React components to native mobile components using Objective-C and Java APIs. Developers can get started using Expo or React Native CLI. Expo is easier for beginners while CLI allows more customization and third party libraries. Core concepts include components, JSX, state, props, and unidirectional data flow. React Native also includes tools like live reloading and hot reloading for faster development.

Introduction to react nativeDani Akash

This document introduces React Native, a framework for building mobile apps using React. It allows building Android and iOS apps with shared code. React Native uses a virtual DOM for fast rendering. Components manage state and receive data through props. Lifecycle methods handle mounting, updating, and unmounting. Setting up requires Node.js, React Native CLI, and Android Studio or Xcode. Hot reloading, Flexbox layouts, and libraries like Lottie and React Navigation make development easier.

[Final] ReactJS presentation洪鹏发

React JS is a JavaScript library for building user interfaces. It uses a virtual DOM to efficiently update the real DOM and render user interfaces from components. Components are reusable pieces of UI that accept input data via properties but maintain private state data. The lifecycle of a component involves initialization, updating due to state/prop changes, and unmounting. React uses a single-directional data flow and the concept of components makes code modular and reusable.

INTRODUCTION TO REACT JAVASCRIPT FOR BEGINNERS.pptxJamesGedza1

JSX (JavaScript XML) is a crucial feature of React as it allows developers to write HTML-like syntax directly within JavaScript code. This blend of HTML and JavaScript simplifies the process of creating dynamic, interactive user interfaces by providing a more readable and maintainable code structure. JSX enables components to visually resemble HTML, making it easier for developers to understand and work with. Furthermore, it helps React efficiently update and render UI elements by translating JSX into JavaScript that browsers can execute, improving performance and providing a smoother development experience. Overall, JSX enhances code clarity and developer productivity while maintaining the full power of JavaScript. Additionally, JSX offers a more intuitive way to manage UI elements and their behavior within React components. By combining the rendering logic and UI structure in one place, developers can quickly see how changes in state or props affect the rendered output. This declarative approach makes it easier to debug and maintain large applications, as developers can track the flow of data and visualize the component tree more effectively. JSX also supports the use of JavaScript expressions within curly braces, allowing for dynamic content rendering, such as conditionally displaying elements or looping through arrays to create lists. This flexibility not only speeds up development but also fosters the creation of highly interactive and responsive user interfaces.

Dust Suppressants: A Sustainable Approach to Dust Pollution ControlJanapriya Roy

This journal explores the growing field of bio-organic dust suppressants as a sustainable solution to dust pollution. It reviews the working principles of dust suppression, key performance indicators, and the latest research on using natural materials like polysaccharides, lignin, proteins, and agricultural wastes. It also highlights current challenges and future directions to enhance the durability, cost-effectiveness, and environmental safety of bio-based dust control technologies. A valuable reference for researchers, environmental engineers, and industry professionals seeking eco-friendly dust management solutions. Dust pollution, whether natural or anthropogenic, poses significant threats to both the environment and public health. Effective dust suppression technologies are essential in mitigating airborne particulate matter, especially in industrial, mining, and construction settings. Recently, bio-organic materials have emerged as promising raw materials for eco-friendly dust suppressants. This paper explores the working principles of dust suppressants, key performance evaluation indices, and the current progress in developing bio-based dust control agents using polysaccharides, lignin, proteins, microorganisms, and agricultural or forestry waste. It also discusses existing challenges and future research directions for enhancing the efficiency and applicability of bio-organic dust suppressants. Working Principles of Dust Suppressants Dust suppressants operate primarily through three interrelated mechanisms: wetting, coagulation, and consolidation. Wetting: This mechanism involves the application of dust suppressants to reduce the surface tension of water, allowing it to penetrate and coat dust particles. This increases the weight and cohesion of the particles, causing them to settle quickly. Surfactants and hygroscopic agents are commonly used in this approach. Coagulation: Dust particles are brought together to form larger aggregates through electrostatic interactions or binding agents, which helps in accelerating their settling. Consolidation: A more long-term effect where the suppressant forms a crust or mesh-like structure over the dust-prone surface, physically stabilizing it and preventing re-entrainment of particles by wind or vehicle movement. Bio-Organic Materials in Dust Suppressants The shift toward natural, renewable, and biodegradable components has led to extensive research on the use of various bio-organic substances, including: Polysaccharides: Starch, cellulose derivatives, and chitosan can form gels or films that stabilize surfaces. Lignin: A byproduct of the paper industry, lignin offers strong binding capacity and is naturally water-resistant. Proteins: Derived from agricultural waste, proteins like casein and soy protein can enhance binding and wetting. Microorganisms: Certain bacteria and fungi can produce biofilms or exopolysaccharides that trap dust particles. Agricultural and Forestry Wastes: Residues su

ADVXAI IN MALWARE ANALYSIS FRAMEWORK: BALANCING EXPLAINABILITY WITH SECURITYijscai

With the increased use of Artificial Intelligence (AI) in malware analysis there is also an increased need to understand the decisions models make when identifying malicious artifacts. Explainable AI (XAI) becomes the answer to interpreting the decision-making process that AI malware analysis models use to determine malicious benign samples to gain trust that in a production environment, the system is able to catch malware. With any cyber innovation brings a new set of challenges and literature soon came out about XAI as a new attack vector. Adversarial XAI (AdvXAI) is a relatively new concept but with AI applications in many sectors, it is crucial to quickly respond to the attack surface that it creates. This paper seeks to conceptualize a theoretical framework focused on addressing AdvXAI in malware analysis in an effort to balance explainability with security. Following this framework, designing a machine with an AI malware detection and analysis model will ensure that it can effectively analyze malware, explain how it came to its decision, and be built securely to avoid adversarial attacks and manipulations. The framework focuses on choosing malware datasets to train the model, choosing the AI model, choosing an XAI technique, implementing AdvXAI defensive measures, and continually evaluating the model. This framework will significantly contribute to automated malware detection and XAI efforts allowing for secure systems that are resilient to adversarial attacks.

2. What is React? • Popular Java Script Library • Web Development • Components as Lego Blocks • Reactive • JSX • Ex. Instagram, Facebook, Airbnb

3. JSX Java Scrip XML const myelement = <h1>I Love JSX!</h1>; ReactDOM.render(myelement, document.getElementById('root')); const myelement = React.createElement('h1', {}, 'I do not use JSX!'); ReactDOM.render(myelement, document.getElementById('root'));

4. What is React Native? • Java Script Framework • Cross Platform Mobile App Development • Flux (Native Modules / API) • Third-Party Libraries and Modules • Write Once Use Anywhere • Live Reload • Ex. Instagram, Facebook, UberEATS, Spotify

5. Why React Native? Cross Platform Java Script Perfomance Third Party Components Developer Community Career Opportunities

6. React Components

7. Component • Class Component • Function Component

8. Life Cycle

9. Import Export • Use to access Components/Functionality in other files • Default Export // import import MyDefaultComponent from "./MyDefaultExport"; // export const MyComponent = () => {} export default MyComponent;

10. Import Export • Named Export // ex. importing a single named export import { MyComponent } from "./MyComponent"; // ex. importing multiple named exports import { MyComponent, MyComponent2 } from "./MyComponent"; // ex. giving a named import a different name by using "as": import { MyComponent2 as MyNewComponent } from "./MyComponent"; // exports from ./MyComponent.js file export const MyComponent = () => {} export const MyComponent2 = () => {}

11. Props • Props is short form of properties • Used to pass data between React components

12. State • Allows components to create and manage their own data. • They can create and manage their own data with state.

13. Environment Setup Node Expo CLI Quick Start nmp Yarn React Native CLI https://reactnative.dev/docs/environment-setup

14. React Native CLI • XCode or Android Studio • brew install node • brew install watchman • npx react-native init {ProjectName} • npx react-native start • npx react-native run-ios • npx react-native run-android

15. React Native vs. Native • When to use • Development Speed • Testing and Debugging • Security

16. Summary • It is an excellent framework that is easy to learn & offers good performance as well as an interface that is comparable to native apps. • There is no doubt that React Native is one of the best cross-platform mobile application frameworks. It is open-source and has a strong community. • UI rendering in React native is excellent. There are few limitations of React Native but it solely depends upon the developer and his vision.
