Lotka Volterra Systems

Lotka Volterra Systems analizator
 This program is useful to study Lotka Volterra systems. These systems are ruled by two differential equations called the Lotka-Volterra equations and also known as the predator-prey equations. They are a pair of first order, non-linear, differential equations frequently used to describe the dynamics of biological systems in which two species interact, one a predator and one its prey. This name is a bit misleading since the systems are not always composed of a predator and a prey. Indeed, in this article, we are going to study a system in which sheeps and rabits interact and compete for food.
It is worthy to mention that this Java application is really interesting because it uses applied numerical analysis to solve the equations, that is to say, it doesn't solve the equations algebraically but instead of that, it uses the Runge Kutta method (order 4) with an step of 0.01. (this means a truly good precission for small systems).

Quantum Mechanical Systems Simulator
 This program simulates four different quantum mechanical systems called the infinite well, the harmonic oscilator, the step, and the barrier. The difference among them is the potential distribution along the X axis. These are the most common potentials when studying the Schrodinger equation for the wave function that reads:

[PC-Game]Bounce&Expoilt

[PC-Game]Bounce&Exploit  In this game all you have to do is to avoid the ball from crossing the line you are deffending. If you fail and the ball passes through, you will lose one life (you start with 4). As the time goes by, your score increases but the speed of the ball increases too. In the middle of the screen there are two cars that can be hit by the ball but if they are hit, the ball will increase its speed in the way the car was moving. Moreover, a skilled handling of the paddle can give the ball some effect, what can be useful to decelerate the ball. Regarding the difficulty levels, when the gammer starts the application, he can choose the average initial speed of the ball and the size of the paddle.
You can download this game here or visiting the downloads section.

Basic Calculator (II)
This is another calculator, also programmed using Java, which has more or less the same functions than the other calculator. The user is never able to write sytax. errors since the buttons are only enabled when an operation is not forbidden.
Rubik Cube 3x3 java solver

Rubik Cube 3x3 Java Package
 We have programmed a java package that is able to solve the 3x3x3 rubik cube using two different methods. The first one is the 'force method' that can solve the cube if it has been scrambled in few movements but it is useless if the cube is completely scrambled. The 'classical method' is the best one due to the fact that it can solve the cube in few seconds using almost the same amount of movements as a normal person would use. Moreover, the package has more methods that allow the user to get and set information of the cube as well as to get a current image of the unfolded cube.
You can find more information visiting SourceForge: http://sourceforge.net/projects/rubikcube3x3pac/

 Basic Calculator
This calculator has been programmed using java. It is usefull to calculate simple operations such as add, subtract, multiply, divide, and so on. It can also work with trigonometric, exponential, and logarithmic operations. The operating mode is algebraic for simple operations and RPN for operations like sin, cos, tan, exp.... The calculator has a correction system in order to prevent the user from generating syntax errors. This way the user can't write wrong syntaxes due to the fact that instead of processing an incorrect operation, a red light will warn the user.
