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:

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.
