Abstract The digital technologies introduced to the market the Web technology; this completely
fulfills all the requests connected with the information cost, stocking and spreading [3].
From these first steps where the sites were simple visiting cards, iterative processes have
been created and developed. Once with the passing to an informational society, a novelty
is represented by the distributed systems of big dimensions, which facilitates the access
to a great variety of resources [7]. In the following study, using the book Numerical
Library in Java for Scientists and Engineers [9]. It offers for each subject a general
discussion, a certain amount of mathematical analysis, a certain discussion of algorithm
and the most important, the implementation of these ideas in areal mode, as routines.
This paper presents a graphic generator for physical phenomena based on numerical
calculation using distributed systems. Is another vision of understanding of the
phenomenon based on experiments using mathematical. There is a proper equilibrium
among these ingredients for each subject.
1. Introduction
The apparition of the web services represents a broader scale for the promoters
‘communication.
When a promoter wants to realize a web service, he has two possibilities, both of them
being determined by the characteristics of the web service itself [8].It is known the fact
that by using the web technologies, the information uses many sources.
Beginning with the web services realized on the basis of the numerical calculation–my
own prior accomplishment–I want to realize a soft which helps the instruction in physics
[6].
Thus, there is a series of softs connected to the elementary notions, but also focused
on a specific phenomenon.
The web services for physics in education which I want to realize represent a step ahead.
Generally, the application domains for the educational systems are scientific domains,
such as: physics, mathematics, chemistry, the life science, informatics,
telecommunications, foreign languages, accounting, banking, energy field, health. They
match the fields rich in structured pieces of knowledge, not too complex and which do
not imply behavior relations between the users.
2. The Adaptation of the Educational System to the
User
The adaptation of the educational system to the user depends on the type of the
learning field, the level of knowledge at the beginning of the educational process, the
purpose of the instruction process, the user personality and the implemented cognitive

model. The adaptation can be realized under a few aspects:
a) personalization – it leads to adapted educational
systems, from the point of view of the content, the
structure, the function of the studying person.
b) assessing – is the mechanism which verifies the practice
abilities and the theoretical abilities during the
educational process and the self-correction.
c) diagnosis – refers to the automatic diagnosis of the
necessary characteristics of the users for the
personalization process or for the diagnosis of the errors
the users made during the evaluation process.
The system – user communication is an open approach of
the educational system, able to sustain a dialogue with the
user.
3. The Web Service as a Graphics
Generator
As long as the informatics and communications
technology evolve, their implications on the educational
system are difficult to be foreseen [2]. There will be always
new opportunities, new difficulties, but there will also be
results and benefits.
Computers simulations seem to be the most efficient
methods of using the computers in physics. There are
encouraged processes used in research physics: for
determining the cause of an effect, in prognosis and also for
research data interpreting.
As a rule, the simulations develop an inductive and
deductive way of thinking, by assuring the capacity of
problem solving, the formulation of new hypotheses and tests
realization.
Beginning with these aspects and using the web services
for numerical calculation subsequently realized, I selected a
series of mathematical functions, useful for the equations
used for the continuous electricity, for the calculation of the
inertia forces on the ground surface, for the calculation of the
dynamics of the variable weight point for finding the
admissible resistance, in sounds producing and propagating.
4. The Advantages of Using Web
Services and Graphic Generator
a) the possibility of resolving problems of great
dimensions which do not go in to the client computer
memory
b) the identification of the common costs
c) the reducing of the costs
d) the reducing of the response time
e) the client can be involved in with the problem’s
description
There is a tendency for a rapid pass to the implementer
part, but we consider that every stage must breakthrough with
a maximum degree of responsibility, in order to eliminate the
wrong results [10].
The inductive or deductive way of thinking, developed by
simulations, is the one which assures the capacity of problem
solving, hypotheses formulating and tests realization, for
investigating the physics processes and phenomena.
The graphic interface the user finds is a simple one, but
extremely efficient, because it is very generalized, for every
type of study.
The platform is divided in to two working areas: the
former is designed o the 14 functions; the latter is for the
graphs realization for the following physics phenomena: the
motor with continuous current; forces of inertia on the earth
surface; the dynamics of the variable mass point; the
admissible resistance; the bodies floating; sounds production
and propagating.
For every physics phenomena on the ideal case and
particular cases are simulated.
These simulations are joined by instructions and
suggestions for problem solving.
Only the variables introduced by the user are used and they
take values between the minimum and the maximum on the
current page.
Once the values crossing, both the values of the function
obtained from calculation and their coefficients are kept.
Beside, the minimum and the maximum peaks are also kept,
because they are used for graphic presentation. All zones are
seen as values rows and they are treated as such.
Behind all the simulations, in parallel with the functions
mentioned above, there are the following calculation
formulas:

particular ones:

Figure 6. The graphic representation of the sound intensification
We suppose the user has physics notions connected with
this phenomenon. A help for the user is the fact that there are
displayed simultaneously the input data with its proper graph,
the new entry data, the output data and its proper graph, for a
series of measurements.

Figure 7. The graphic representation for the particular cases
The main ideas which result from the above examples are
the following:
a) The necessity of knowing all the equations and the
particular cases which represent the bases of the
physical phenomenon;
b) The possibility of their interpretation depending on the
input data;
c) Simulations for finding another particular cases;
d) The practical understanding of the physics phenomena;
All these comparisons between values and interpretations
upon the graphs depend on the users objectives. It is very
important the fact that the possible user of the application can
use the interface on different levels of knowledge.
5. Conclusions
We presented in this article concepts connected to the
architecture of the distributed systems, showing criteria for a
proper choice in order to use an adequate technology. The
problem we develop is represented by the realization of some
Web Services using methods of numeric calculation [4]. The
applications are created on the Eclipse platform; these are
realized with the solutions offered by the book Numerical
Library in Java for Scientists and Engineers. These solutions
are oriented towards scientific applications based on
numerical calculation. They begin with elementary structures
and group to more complex structures. Grouping and creating
services for each and every, we realized that many functions
used for their construction appeal other functions; we created
a table with those functions appear only one time. The
created web service presents a few physics applications based
on the numerical calculations. The selected phenomena can
assure the construction of more complicated applications.
This method shows the ideal cases which are not found in
nature, but also specific cases.
If one interprets correctly, one can find optimal solutions
to a set of problems; besides there is the possibility of further
usage of the obtained results [5].
The main advantages of using the web service are: the
possibility of solving problems of great dimensions, which
exceed the computer’s memory; we can also identify the
common costs and their reduction; the diminishing of the
time response value; the client can be involved in the
problem description.
