The RAD5500 is a radiation-hardened 64-bit processor core design created by BAE Systems Electronics, Intelligence & Support based on the PowerPC e5500 designed by IBM and Freescale Semiconductor. [ 1 ] [ 2 ] [ 6 ] Successor of the RAD750 , the RAD5500 processor platform is for use in high radiation environments experienced on board satellites ...
PD 5500 is a specification for unfired pressure vessels. It specifies requirements for the design, manufacture, inspection and testing of unfired pressure vessels made from carbon, ferritic alloy, and austenitic steels. It also includes material supplements containing requirements for vessels made from aluminium, copper, nickel, titanium and ...
A simple arithmetic calculator was first included with Windows 1.0. [5]In Windows 3.0, a scientific mode was added, which included exponents and roots, logarithms, factorial-based functions, trigonometry (supports radian, degree and gradians angles), base conversions (2, 8, 10, 16), logic operations, statistical functions such as single variable statistics and linear regression.
A difference engine is an automatic mechanical calculator designed to tabulate polynomial functions. It was designed in the 1820s, and was first created by Charles Babbage. The name difference engine is derived from the method of finite differences, a way to interpolate or tabulate functions by using a small set of polynomial co-efficients.
Friden Calculator Friden Flexowriter. In 1957, Friden purchased the Commercial Controls Corporation of Rochester, New York.This gave them the Flexowriter teleprinter, an electric typewriter capable of being used as part of unit record equipment developed in World War II for the Department of the Navy to automatically type "regret to inform you" letters to the survivors of fallen servicemen ...
On a single-step or immediate-execution calculator, the user presses a key for each operation, calculating all the intermediate results, before the final value is shown. [ 1 ] [ 2 ] [ 3 ] On an expression or formula calculator , one types in an expression and then presses a key, such as "=" or "Enter", to evaluate the expression.
In 1961, the MCP was the first OS written exclusively in a high-level language (HLL). The Burroughs Large System (B5000 [2] and successors) were unique in that they were designed with the expectation that all software, including system software, would be written in an HLL rather than in assembly language, which was a unique and innovative approach in 1961.
However, included with the calculator was a library of over 120 programs that performed common operations in mathematics, geometry, statistics, finance, physics, electronics, engineering, as well as fluid mechanics and materials science. [16] [18] There were over 400 programs in the full Sinclair Program Library. [19]
