Methodology-Spiral Model As per the name‚ spiral model is a software development methodology that is arranged in a spiral shape. It was proposed by Barry Boehm and is mostly used to handle high risk and also large projects. The spiral model uses iterations‚ meaning similar steps that are repeated until the needs are satisfied. This methodology is suitable when requirements are not clear to the software developers. Prototypes are made in this methodology and given to the users to be tested to change

COMMENTARY - REINDEER AND ENGINE This poem‚ "Reindeer and Engine" is by Josephine Jacobsen. It is set in a ’Finnish forest track’ where a reindeer is being chassed by a train. It flees from the light of the train as it ’runs’ forward trying to escape. This is a narrative poem because it tells a story from an omniscient point of view. It is written in four stanza’s each one telling a different part of the story. The first idea we come across is that of light. ’The great round eye’ in the first line

Using an Automated Response System Kathy Gearhart IT/284 August 24‚ 2012 Robert McDonald Using an Automated Response System According to "Automated Systems" (n. d.)‚ “An Automated Response System (ARS) is any system where an input is provided and a machine or computer carries out a process that produces an output” (Introduction). Basically this is a computerized assistant who directs the customer’s phone calls dependent on what their input to questions or menus is. The ARS is quite normal

Internal Combustion Engines Introduction Internal Combustion Engine‚ a heat engine in which the fuel is burned ( that is‚ united with oxygen ) within the confining space of the engine itself. This burning process releases large amounts of energy‚ which are transformed into work through the mechanism of the engine. This type of engine different from the steam engine‚ which process with an external combustion engine that fuel burned apart from the engine. The principal types of internal combustion

Turboprop engines Turboprop engines are a type of aircraft powerplant that use a gas turbine to drive a propeller. The gas turbine is designed specifically for this application‚ with almost all of its output being used to drive the propeller. The engine’s exhaust gases contain little energy compared to a jet engine and play a minor role in the propulsion of the aircraft. The propeller is coupled to the turbine through a reduction gear that converts the high RPM‚ low torque output to low RPM‚
