Thru development, the reactor and its steam turbines had been reduced greatly in size, and also in complexity, allowing a single propeller to be used, the navy said.

This change was pushed forward by the development of heavier naval guns ( the ironclads of the 1880s carried some of the heaviest guns ever mounted at sea ), more sophisticated steam engines, and advances in metallurgy which made steel shipbuilding possible.

Improving on the design of the 1712 Newcomen steam engine, the Watt steam engine, developed sporadically from 1763 to 1775, was a great step in the development of the steam engine.

Later development led to steam locomotives and great expansion of railway transportation.

The development of the steam engine provided a reason to compare the output of horses with that of the engines that could replace them.

The supply of cheaper iron and steel aided the development of boilers and steam engines, and eventually railways.

The development of the stationary steam engine was an essential early element of the Industrial Revolution ; however, for most of the period of the Industrial Revolution, the majority of industries still relied on wind and water power as well as horse-and man-power for driving small machines.

The advent of the Age of Enlightenment provided an intellectual framework which welcomed the practical application of the growing body of scientific knowledge — a factor evidenced in the systematic development of the steam engine, guided by scientific analysis, and the development of the political and sociological analyses, culminating in Adam Smith's The Wealth of Nations.

Because of the danger of exploding boilers, which were in a very primitive stage of development, and the ongoing issues with leaks, Watt restricted his use of high pressure steam – all of his engines used steam at near atmospheric pressure.

Stephenson played a pivotal role in the development and widespread adoption of steam locomotives.

* James Watt makes a breakthrough in the development of the steam engine by constructing a model with a separate condenser.

Practical reasons also played a role in this development: just as in the bourgeois homes of the past, one reason for separating the kitchen was to keep the steam and smells of cooking out of the living room.

A sauté pan must be large enough to hold all of the food in one layer, so steam can escape-which keeps the ingredients from stewing, and promotes the development of fond.

A fact important to the later development of the steam locomotive by others was that, in 1797 and 1798, Richard Trevithick came to live in Redruth next door to the house where William Murdoch lived ( 1782 to 1798 ).

The basic significance of this invention helped them to follow it rapidly in 1855 by the development of a unique precision gear cutting and dividing engine.

In October 1994, Borland sold Quattro Pro and Paradox to Novell for $ 140 million in cash, repositioning the company on its core software development tools and the Interbase database engine and shifting toward client-server scenarios in corporate applications.

In parallel to the development of the bus was the invention of the electric trolleybus, typically fed through trolley poles by overhead wires, which actually preceded, and in many urban areas outnumbered, the conventional engine powered bus.

Direct fuel injection which can inject fuel only at the time of fuel ignition ( similar to a diesel engine ) is another recent development which also allows for higher compression ratios on gasoline engines.

See the development of the hot bulb engine and indirect injection for historical significance.

The development of Doom started in 1992, when John D. Carmack developed a new 3D game engine, the Doom engine, while the rest of the id Software team finished the Wolfenstein 3D prequel, Spear of Destiny.

The popularity of Doom led to the development of a sequel, Doom II: Hell on Earth ( 1994 ), as well as expansion packs and alternate versions based on the same game engine, including The Ultimate Doom ( 1995 ), Final Doom ( 1996 ), and Doom 64 ( 1997 ).

* 1937: BMW 114 experimental airplane diesel engine development.

Earlier automobile engine development produced a much larger range of engines than is in common use today.

* The Haynes Aero Skyblazer is a development stage vehicle that uses a single turbofan engine to provide thrust in the air and to generate electricity to power electric motors for ground travel.

* 1957 – Felix Wankel's first working prototype ( DKM 54 ) of the Wankel engine runs at the NSU research and development department Versuchsabteilung TX in Germany

During development, it was found that the comparatively heavy rear-mounted engine moved the center of mass of the vehicle rearwards.

The First Industrial Revolution, which began in the 18th century, merged into the Second Industrial Revolution around 1850, when technological and economic progress gained momentum with the development of steam-powered ships, railways, and later in the 19th century with the internal combustion engine and electrical power generation.

Behe asserts that the absence of any one of these proteins causes the flagella to fail to function, and that the flagellum " engine " is irreducibly complex as if we try to reduce its complexity by positing an earlier and simpler stage of its evolutionary development, we get an organism which functions improperly.

However Id Tech 4 had far fewer licensees than the Unreal Engine from Epic Games, due to the long development time that went into Doom 3 which Id had to release before licensing out that engine to others.

Apart from developing, manufacturing, and selling the Koenigsegg line of supercars, Koenigsegg is also involved in " green technology " development programs, beginning with the CCXR (" Flower Power ") flexfuel supercar and continuing through the present with the Agera R. Koenigsegg is also active in development programs when it comes to plug-in electric cars ' systems and next-generation reciprocating engine technologies.

Thus, although the agenda of external assistance in the economic sphere are cumulative, and many of the policies suggested for nations in the earlier stages remain relevant, the basic purpose of American economic policy during the later stages of development should be to assure that movement into a stage of self-sustaining growth is not prevented by lack of foreign exchange.

The positive development, during adolescence, of this capacity to think and to feel strongly and with increasing independence, and to identify overtly either with or against given ideas, values, and practices, depends to a considerable degree on both previous and present opportunities for developing autonomy, initiative, and self-certainty.

Institutionally, anthropology emerged from the development of natural history ( expounded by authors such as Buffon ) that occurred during the European colonization of the seventeenth, eighteenth, nineteenth and twentieth centuries.

The development of toolpath control via jigs, fixtures, for machine tools ( such as the screw-cutting lathe, metal planer and milling machine ) during the early 19th century provided the prerequisites for the modern assembly line by making interchangeable parts a practical reality.

Such a deep controversy within the Church during this period of its development could not have materialized without significant historical influences providing a basis for the Arian doctrines.

In 1991, the London Science Museum built a complete and working specimen of Babbage's Difference Engine No. 2, a design that incorporated refinements Babbage discovered during the development of the Analytical Engine.

A long series of cultural development culminated in the expansion of the Inca civilization and Inca Empire in the central Andes during the 15th century.

As well as this, factories such as flour mills and beer breweries and mining practices resulted in the creation of infrastructure such as roads and railway lines, during a development period that lasted until 1904.

Sumerian literature continued in rich development during the Akkadian period ( a notable example being Enheduanna ).

However, studies have shown that blind cave fish embryos begin to grow eyes during development but then something actively stops this process and flesh grows over the partially grown eyes.

Acceptance test cards are ideally created during sprint planning or iteration planning meeting, before development begins so that the developers have a clear idea of what to develop.

Acceptance testing is a term used in agile software development methodologies, particularly Extreme Programming, referring to the functional testing of a user story by the software development team during the implementation phase.
