Metro Railways Introduction Metro railways are also known as rapid transit system. It is a high capacity carrier which transports large number of people across small distances seamlessly. It is run automatically by computer without human intervention. There is no driver who drives it; rather it is run on automatic system. It is used to transport a large of people over short distances in metropolitan or urban cities. The need for metro rails is due to the increase in population‚ increase in traffic

RAD Rapid Application Development What is RAD and what does it involve? Rapid Application Development‚ or RAD for short‚ is a method of developing software with the minimum amount of planning; this allows the programme or software to be completed much faster than traditional software development. The two most popular RAD systems are Visual Basic and Delphi. In what circumstances would RAD be used and why? RAD would be used when the programme would be under a heavy time constraint‚ therefore

RAD (Rapid Application Development) refers to a development life-cycle designed to give much faster development and higher-quality results than those achieved with the traditional life-cycle "Rapid Application Development is a software development process developed initially by James Martin in the 1980s. The methodology involves iterative development‚ and the construction of prototypes. Traditionally the rapid application development approach involves compromises in usability‚ features‚ and/or execution

The Delhi Metro is a rapid transit system serving Delhi‚ Gurgaon‚ Noida and Ghaziabad in the National Capital Region of India. The network consists of six lines with a total length of 189.63 kilometres (117.83 mi) with 142 stations of which 35 are underground. It has a combination of elevated‚ at-grade and underground lines and uses both broad gauge and standard gauge rolling stock. Four types of rolling stock are used: Mitsubishi-ROTEM Broad gauge‚ Bombardier MOVIA‚ Mitsubishi-ROTEM Standard gauge

Rapid application development Republished from Developers.net Rapid Application Development (RAD) is a marketing buzzword that almost every software development tool uses‚ yet one that rarely applies. At a high level it is an Application Development technique that uses Prototypes‚ Iterative Customization‚ and CASE Tools. This article will focus on RAD: its history‚ advantages and disadvantages‚ appropriateness for various problems‚ core elements‚ process‚ and additionally will focus on CASE tools

This will serve as the guide to the proponents on how they will conduct the study systematically in order to fulfill the study’s objectives. Software Development and Methodology The Rapid Application Development (RAD) approach would be used to develop the system because of time constraints in the development schedule. RAD is a linear sequential software development process model that emphasized on extremely short development cycle using

OBJECTIVE: 3D printing is a form of additive manufacturing technology where a three dimensional object is created by laying down successive layers of material. It is also known as rapid prototyping‚ is a mechanized method whereby 3D objects are quickly made on a reasonably sized machine connected to a computer containing blueprints for the object. The 3D printing concept of custom manufacturing is exciting to nearly everyone. This revolutionary method for creating 3D models with the use of inkjet

talk about “ Dreams” There are many things that make dreams happen. for example being in a good mood not being angry and getting a good nights sleep can make it happen. You can dream during(REM) rapid eye movement. What is rapid eye movement. Rapid eye movement (REM) is the stage of sleep characterized by rapid movements of the eyes. REM sleep typically occupies 20–25% of total sleep‚ about 90–120 minutes of a night’s sleep. REM sleep is considered the deepest stage of sleep‚ and normally occurs close
