The simulation process is one of the largest industrial engineering tools, which utilize to represent a process by another that much more simple and intended. This simulation is in some cases almost indispensable, as we shall see below. In other cases it is not so, but this procedure becomes more complicated.
Simulation is the representation of a process or phenomenon using a simpler, to analyze its features, but the simulation is not only that is also very ordinary today, it may be from simulating a test, which makes the teacher to his pupil for an examination of the ministry, the production of textiles, food, toys, construction of infrastructure through models, to virtual training of fighter pilots.
The recreational applications, today widespread and largely improved by advances in this field, are specially designed to create a hobby that will succeed to the routine to humans, and that the best would otherwise be impractical due to cost . These are to create artificial environments and decorated with sound in some cases, to achieve perfect simulation of any content, creating the perfect pastime
One of the main projects of the simulation futuristic but very expensive, it is in the field of physical minosvalias, since its design should include, especially in the field of the blind, a special censors, who adapted, would get a simulated view allowing the land to give vision (in this case) to these people, even in some cases give greater powers to mediate human reality show is real at the same time.

System of symbols or signs used to express numbers.
The earliest forms of numerical notation were simply straight lines, vertical or horizontal, each of which represents the number 1. As this system was extremely cumbersome to handle large numbers and to make trades. As early as 3400 BCE in Egypt and Mesopotamia used a specific symbol to represent the number 10.
In the Babylonian cuneiform notation symbol used for 1 was the same for 60 and its powers., The value of the symbol was given by its context.
In ancient Greece there are two parallel numbering systems. The first was based on initial numbers, the number 5 was indicated by the letter (PI), 10 with the letter (delta) 100 with the letter (eta), the 1000 with the letter (chi) and 1000 with the letter (mu). In the second set were used all the letters of the Greek alphabet plus three taken from the Phoenician alphabet and numerals. The advantage of this system was that with little amount of numbers could be expressed large numbers, but knowing you had to memorize a total of 27 symbols. Read the rest of this entry »
