Abstract Engine oil-derived ash particles emitted from internal combustion IC engines are unwanted by-products, after oil is involved in in-cylinder combustion process. Since they typically come out together with particulate emissions, no detail has been reported about their early-stage particles other than agglomerated particles loaded on aftertreatment catalysts and filters. To better understand ash formation process during the combustion process, differently formulated engine oils were dosed into a fuel system of a gasoline direct injection GDI engine that produces low soot mass emissions at normal operating conditions to increase the chances to find stand-alone ash particles separated from soot aggregates in the subnm size range. The STEM-XEDS results showed that regardless of formulated oil type and particle size, Ca, P and C were always contained, while Zn was occasionally found on relatively large particles, suggesting that these elements get together from an early stage of particle formation. C Elsevier Ltd.Charles Babbagecomputer pioneer, designed two classes of engine, Difference Engines, and Analytical Engines. Difference engines are so called because of the mathematical principle on which they are based, namely, the method of finite differences. The beauty article source the method is that it uses only arithmetical addition and removes the need for multiplication and division which are more difficult to implement mechanically. Difference engines are strictly calculators. They crunch numbers the only way they know how - by repeated addition according to the method of finite differences. They cannot be used for general arithmetical calculation.
The Analytical Engine is much more than a calculator and marks the progression from the mechanized arithmetic of calculation to fully-fledged general-purpose computation. There were at least three difference engine and analytical engine at different stages of the evolution of his ideas. So it is strictly correct to refer to the Analytical Engines in the plural. Babbage's calculating engines are decimal digital machines.

They are decimal in that they use the familiar ten numbers '0' to '9' and they are digital in the sense that only whole numbers are recognized as valid. Number values are represented by gear wheels and each digit of a number has its own wheel.
If a wheel comes to rest in a position intermediate between whole number values, the value is regarded as indeterminate and the engine is designed to enyine to indicate that the integrity of the calculation has been compromised.
Jamming is a form of error-detection. Babbage difference engine and analytical engine using number systems other than decimal including binary as well as number bases 3, 4, 5, 12, 16 and He settled for decimal out of engineering efficiency - to reduce the number of moving parts - as well as for their everyday familiarity. Babbage began in with Difference Engine No. The design describes a machine to calculate a series of values and print results automatically in a table. Integral to the concept of the design is ebgine printing apparatus mechanically coupled to the calculating section and integral to it. Difference Engine No. From time to time Babbage changed the capacity of the Engine. The design shows a machine calculating with sixteen digits and six orders of difference. The Engine called for some 25, parts shared equally between the calculating section and the printer.

Had it been built it would gogo drama weighed an estimated four tons and stood about eight feet high. Work was halted on the construction of the Engine in following a dispute with the cold summary, Joseph Clement.
Government funding was finally axed in With the construction analyticall stalled, and freed from the nuts and bolts of detailed construction, Babbage conceived, ina more ambitious machine, later called Analytical Engine, a general-purpose programmable computing engine. The Analytical Engine has many essential features found in the modern digital computer. It was programmable using punched cards, an idea borrowed from the Jacquard loom used for weaving complex patterns in textiles. The Engine had a 'Store' where numbers and intermediate results could be held, and a separate 'Mill' where the arithmetic processing was performed. It had an internal repertoire of the four arithmetical functions and could perform direct multiplication and division.
It was also capable of functions for which we have modern names: conditional branching, looping iterationmicroprogramming, parallel processing, iteration, latching, polling, and pulse-shaping, amongst others, though Babbage nowhere used these terms. It had a variety of outputs including hardcopy printout, punched cards, graph plotting and the automatic production of stereotypes - trays of soft material into which emgine were impressed that could be used as molds for making printing plates.
The logical structure of the Ebgine Engine was essentially the difference engine and analytical engine as that which has dominated computer design in the electronic era - the separation of the memory the 'Store' from the central processor the 'Mill'serial operation using a 'fetch-execute cycle', and facilities for inputting and outputting data and instructions. Calling Babbage 'the first computer pioneer' is not a casual tribute. With the groundbreaking work on the Analytical Engine largely complete by difference engine and analytical engine, Babbage began to consider a new difference engine.
Between and he completed the design of Difference Engine No. This Engine calculates with numbers thirty-one digits long and can tabulate any polynomial up to the seventh order.]
What words... super, an excellent phrase
Prompt, where I can read about it?
Now all is clear, many thanks for the help in this question. How to me you to thank?
