systems to computer programs that create comput-
er-generated environment or virtual environment.
It helps to understand, explore, and control systems
in many areas of science and engineering. Any
phenomena that can be reduced to mathematical
data can be simulated on a computer and used
for designing a model of a problem or a course
of events. For example, simulation of probabili-
ties for market events may examine the effect of
a price change on a market and the behavior of
competitors and consumers in response to a price
change. Computer simulation can refer to the
process of imitating a real phenomenon with a set
of mathematical formulas (for example, weather
conditions, chemical reactions, or biological pro-
cesses). A great many simulation languages exist,
e.g., Simula. Simulation is a powerful tool for
imaging concepts and structures as computational
models involving programs and processes running
on one or a set of computers. In technology, it is
an artificial situation or environment. Simulation
may refer to virtual reality techniques, which use an
interactive computerized simulation or synthesis
of an experience in several senses.
Computer simulation, visualization and da-
tabases are considered new cultural forms of
the information society (Vande Moere, 2008).
By creating a model, we can predict effects of
the conditions of the thing being simulated.
Computational simulations describing the space
phenomena can be enhanced with the use of a
method of mapping colors. In a false-color image
close correspondence between subject color and
image color is violated. Complex waveforms are
converted to a composite color map with the use of
such variables as amplitude, frequency, and phase.
Colors represent measured intensities outside the
visible part of the electromagnetic spectrum. This
method allows the users immediate visual feed-
back; it proved to be an effective educational tool
(Cox, 1988). Simulation may also refer to virtual
reality techniques for learning and training, as it
happens when animated runways and enemy flight
forces are recreated in a room called a simulator.
A real-time simulator also involves a headset, a
chair, and other elements to ensure that it moves
and sounds like the real thing. Ready simulation
software packages are designed for specific kinds
of computer simulation. Multimedia applications
that combine text, high-quality sound, two- and
three-dimensional graphics, animation, photo im-
ages, and full-motion video are often simulated.
Computer simulations that imitate real phe-
nomena often use computer programs that simulate
facts and events and show the effects of changes
induced in a particular setting or a model under
study. Mathematicians create simulations to work
on the mathematics foundations, the formulation
and analysis of the language, axioms, and logical
methods on which mathematics rests. Simulation
applications in object-oriented programming and
in computer program (software) design support
combining data and procedures (sequences of
instructions). Mathematical models that imitate
internal processes in the fields such as archeol-
ogy, art, architecture history, and many other
fields can predict the system behavior in the
changed circumstances. Computer simulations of
physical and mathematical systems use computa-
tional algorithms of different kinds, for example,
Monte Carlo methods relying on repeated random
sampling, to perform calculations. Abstract data
such as those needed for financial models, textual
analysis, transaction data, network traffic simu-
lations or digital libraries, lack a natural notion
of position in space (Vande Moere, 2008). They
are often too complex to compute them with a
deterministic algorithm and present as a graph or a
matrix. Computer generated imagery simulations
are intense graphical animated displays that show
motion, changes in structures, and allow predict-
ing events. Typical example is an aircraft flight
simulator, equipment that represents real condi-
tions in an aircraft or spacecraft used for the airline
and fighter pilot training. Simulations model the
dynamics of processes and events such as struc-
tural engineering, fluid flow, or aerodynamics, a
study of gases in motion and of the forces acting
