Service Workers / Offline Support
Both indicate offline by graying out their UIs so you know “live” prices may be different.
You’re in control of how much of your UX is available offline.
You can offline-cache just the application shell, all of the data or offer a limited,
useful set of stale data like Housing.com and Flipkart do.

Backend & Frontend architecture scalability & websocketsAnne Jan Brouwer

Single Page Application presentationJohn Staveley

The document discusses a journey to building a single page application using AngularJS and BreezeJS. It describes the initial solution using jQuery with problems around navigation and two-way binding. AngularJS solves these issues with routing and two-way binding. BreezeJS simplifies working with data by removing boilerplate code for model creation, queries, validation and only saving changed data. Unit testing is also enabled through Angular's dependency injection and separation of concerns. The presentation concludes that single page applications are well-suited for cross-platform mobile apps that avoid app stores, and that AngularJS and BreezeJS improve code testability and reduce data access code.

web, spa vs traditional - 2016Yauheni Nikanovich

This document compares single page applications (SPAs) to traditional websites. SPAs load all necessary resources on the initial page load, then dynamically load any additional content. This allows the URL to be frequently updated to simulate page transitions while avoiding full page reloads. SPAs require less server-side processing than traditional sites since more logic runs in the browser. Well-written SPAs are convenient for users because they are responsive like native apps, can notify users of state changes, and work across different devices and platforms similarly to regular websites.

Dynamic websites lec5Belal Arfa

This document discusses dynamic websites using PHP with an Oracle database. It covers: 1. Installing WAMP to set up a local web development environment 2. The basics of web programming including static vs. dynamic pages and how servers and browsers communicate 3. Static pages only require a web server and HTML file while dynamic pages also need a program like PHP to generate dynamic content from things like a database

Ajax Using JSP with prototype.jsTushar Chauhan

AJAX is a group of technologies used to create asynchronous web applications. It allows for updating parts of a web page without reloading the entire page. This improves responsiveness and allows for more dynamic interactions. Some key benefits of AJAX include more responsive interfaces, ability to update small parts of pages individually, and reduced waiting times. While it increases development complexity, AJAX is widely used in applications that involve heavy server requests, need to display large amounts of data sequentially, or where user interaction is frequent. Common frameworks for implementing AJAX include Prototype.js and Dojo Toolkit. Many large websites use AJAX, including Google Maps, Gmail, and Facebook.

Progressive Web Apps. What, why and howRiza Fahmi

Progressive Web Apps are a new approach to application development that combines the best of the web and the best of native apps. They are reliable, fast and engaging like native apps while also being responsive and capable of being installed like regular web pages. The key technologies that enable Progressive Web Apps are service workers, app manifests, and responsive design. Service workers allow for caching assets and serving cached responses even when offline. App manifests provide metadata that makes the app feel like a native application to the user. Responsive design ensures the app works across different screen sizes.

HTML Hypermedia APIs and Adaptive Web Design - jDays 2013Gustaf Nilsson Kotte

The document discusses using HTML hypermedia APIs and adaptive web design together. It advocates for building APIs that use HTML and hypermedia constraints so the API and web interfaces can share code and templates. This allows optimizing interfaces for both web and API perspectives. The document provides examples of building HTML hypermedia APIs and using them with adaptive web design that responds to different devices and browsers.

Introduction to Progressive Web ApplicationsChris Love

Progressive Web Apps (PWAs) are websites that utilize modern web capabilities to deliver native app-like experiences to users. PWAs are built using common web technologies including HTTPS, service workers, and web app manifests. Service workers allow PWAs to work offline by caching app assets and responding to fetch events. When installed on a user's homescreen, PWAs can load quickly and feel like native applications while retaining the benefits of the web such as being discoverable, installable, and updatable.

Developing Profitable APIs - John Fraser - Platform Aauexpo Conference

The document discusses several challenges and considerations for networks and affiliates in designing and implementing APIs and mashups. It addresses questions around API architecture design, defining standard data formats, scalability, read/write functionality, and support for affiliates. It also covers common challenges like complex programming, browser compatibility, and maintenance, and potential solutions. While mashups require more development and maintenance costs, they also provide opportunities to attract users through new interactive features and access new markets.

HTML Hypermedia APIs and Adaptive Web Design - RuPyGustaf Nilsson Kotte

The document discusses using HTML hypermedia APIs and adaptive web design together. HTML hypermedia APIs use standard HTML to build APIs that follow the hypermedia constraint, where clients interact by following links and submitting forms. Adaptive web design allows a single codebase to work across different devices by responding to features and making content and layout fluid. The document argues that HTML hypermedia APIs and adaptive web design work well together by allowing the same code and templates to be used for both the web interface and API, with separate URLs and optimizations for different perspectives. A demo is shown of a kanban board application built with this approach.

Progressive Web AppSaleemMalik52

“Progressive Web Apps (PWAs) are web applications that load like regular web pages or websites but can offer the user functionality such as working offline, push notifications, and device hardware access traditionally available only to native mobile applications. PWAs are an emerging technology that combine the open standards of the web offered by modern browsers to provide benefits of a rich mobile experience”

Development of MLR, ANN and ANFIS Models for Estimation of PCUs at Different ...Journal of Soft Computing in Civil Engineering

Passenger car unit (PCU) of a vehicle type depends on vehicular characteristics, stream characteristics, roadway characteristics, environmental factors, climate conditions and control conditions. Keeping in view various factors affecting PCU, a model was developed taking a volume to capacity ratio and percentage share of particular vehicle type as independent parameters. A microscopic traffic simulation model VISSIM has been used in present study for generating traffic flow data which some time very difficult to obtain from field survey. A comparison study was carried out with the purpose of verifying when the adaptive neuro-fuzzy inference system (ANFIS), artificial neural network (ANN) and multiple linear regression (MLR) models are appropriate for prediction of PCUs of different vehicle types. From the results observed that ANFIS model estimates were closer to the corresponding simulated PCU values compared to MLR and ANN models. It is concluded that the ANFIS model showed greater potential in predicting PCUs from v/c ratio and proportional share for all type of vehicles whereas MLR and ANN models did not perform well.

The Gaussian Process Modeling Module in UQLabJournal of Soft Computing in Civil Engineering

We introduce the Gaussian process (GP) modeling module developed within the UQLab software framework. The novel design of the GP-module aims at providing seamless integration of GP modeling into any uncertainty quantification workflow, as well as a standalone surrogate modeling tool. We first briefly present the key mathematical tools on the basis of GP modeling (a.k.a. Kriging), as well as the associated theoretical and computational framework. We then provide an extensive overview of the available features of the software and demonstrate its flexibility and user-friendliness. Finally, we showcase the usage and the performance of the software on several applications borrowed from different fields of engineering. These include a basic surrogate of a well-known analytical benchmark function; a hierarchical Kriging example applied to wind turbine aero-servo-elastic simulations and a more complex geotechnical example that requires a non-stationary, user-defined correlation function. The GP-module, like the rest of the scientific code that is shipped with UQLab, is open source (BSD license).

"Boiler Feed Pump (BFP): Working, Applications, Advantages, and Limitations E...Infopitaara

A Boiler Feed Pump (BFP) is a critical component in thermal power plants. It supplies high-pressure water (feedwater) to the boiler, ensuring continuous steam generation. ⚙️ How a Boiler Feed Pump Works Water Collection: Feedwater is collected from the deaerator or feedwater tank. Pressurization: The pump increases water pressure using multiple impellers/stages in centrifugal types. Discharge to Boiler: Pressurized water is then supplied to the boiler drum or economizer section, depending on design. 🌀 Types of Boiler Feed Pumps Centrifugal Pumps (most common): Multistage for higher pressure. Used in large thermal power stations. Positive Displacement Pumps (less common): For smaller or specific applications. Precise flow control but less efficient for large volumes. 🛠️ Key Operations and Controls Recirculation Line: Protects the pump from overheating at low flow. Throttle Valve: Regulates flow based on boiler demand. Control System: Often automated via DCS/PLC for variable load conditions. Sealing & Cooling Systems: Prevent leakage and maintain pump health. ⚠️ Common BFP Issues Cavitation due to low NPSH (Net Positive Suction Head). Seal or bearing failure. Overheating from improper flow or recirculation.

Structural Response of Reinforced Self-Compacting Concrete Deep Beam Using Fi...Journal of Soft Computing in Civil Engineering

Analysis of reinforced concrete deep beam is based on simplified approximate method due to the complexity of the exact analysis. The complexity is due to a number of parameters affecting its response. To evaluate some of this parameters, finite element study of the structural behavior of the reinforced self-compacting concrete deep beam was carried out using Abaqus finite element modeling tool. The model was validated against experimental data from the literature. The parametric effects of varied concrete compressive strength, vertical web reinforcement ratio and horizontal web reinforcement ratio on the beam were tested on eight (8) different specimens under four points loads. The results of the validation work showed good agreement with the experimental studies. The parametric study revealed that the concrete compressive strength most significantly influenced the specimens’ response with the average of 41.1% and 49 % increment in the diagonal cracking and ultimate load respectively due to doubling of concrete compressive strength. Although the increase in horizontal web reinforcement ratio from 0.31 % to 0.63 % lead to average of 6.24 % increment on the diagonal cracking load, it does not influence the ultimate strength and the load-deflection response of the beams. Similar variation in vertical web reinforcement ratio leads to an average of 2.4 % and 15 % increment in cracking and ultimate load respectively with no appreciable effect on the load-deflection response.
