| ONLINE EDUCATIO SYSTEM | srimathi | 25 Apr 2008 |
The main objective is to classify the students in order to predict their final grade Based on features extracted from logged data in an educational web based system. We can give the grades to students through data mining. In data mining we have multiple classifiers. A combination of multiple classifiers leads to a significant improvement in classification performance. We use genetic algorithm to optimize the prediction accuracy.
We are going to apply Genetic programming

| Fingerprints | srimathi | 25 Apr 2008 |
Fingerprints offer an infallible means of personal identification. That is the essential explanation for their having supplanted other methods of establishing the identities of criminals reluctant to admit previous arrests
Many areas of scientific study involve the collection of large amounts of data. Such data must be organized in order to be useful
The patterns of ridges on our finger pads are unique: no two individuals—even identical twins—have fingerprints that are exactly alike

| Recording on a Wire | sharathsathisan | 19 Apr 2008 |
The goal of this experiment is to learn about magnetic recording heads by building and testing a wire recorder. You'll investigate the relationship between recording current and playback voltage. Other variables to investigate are the number of turns used in the coil for the recording head, and the speed of the moving wire.

| Voltage Stabiliser using Zener Diode | Jose Mathew | 15 Aug 2007 |
Voltage stabilizers (zener diodes) can be used as a voltage regulator to provide a constant voltage from a d..c source across a load RL.
By using voltage stabilizers, we can save our electrical equipments to a large extent. Because whenever the input voltage in the circuit increases, by thundering, short circuiting or by any other way, zener diode give only its zener voltage to the appliance as output voltage. Otherwise the appliances will burn out due to high voltage.

| Full Wave Bridge Rectifier | Jose Mathew | 15 Aug 2007 |
By doing this project we came to knew that a full ssswave bridge rectifier can be made without centre tapping transformer. And also we came to find the efficiency of full wave rectifier. For bridge type, no centre tap is required on the transformers. Here much smaller transformers are used. Bridge rectifier is used for high voltage application. For the same secondary voltage, the output voltage is twice that of the centre trapped full wave rectifier.
At the same time some disadvantages are there. Here two

| Construction of Thermoelectric Thermometer | Jose Mathew | 15 Aug 2007 |
? The current is produced due to the difference between cold and hot junction.
? The producing current depends upon the Nature of the metals forming thermocouple.
? The thermo electric current is directly proportional to the temperature of the hot junction.
? When the area of cross section is high the producing electricity is higher.
? When the length increases the producing thermo electricity is decreases.
? The direction of current depends upon the type of metals forming thermo couple.

| Force of Attraction between Solenod and bar magnet | Jose Mathew | 15 Aug 2007 |
Force-current graph is a straight line. This shows that the force of attraction between the bar magnet and the solenoid carrying current is directly proportional to the magnitude of current passing through the solenoid.

| Construction of a Electric Motor | user | 14 Aug 2007 |
- From the findings we can conclude that the speed of the rotation of the coil is directly proportional to the
- No. of turns in coil.
- Power of magnetic field
- Current given to the coil
- Area of the coil.
- The direction of rotation of the coil can be changed by changing the directions of the current.

| Construction Of Telescope | Jose Mathew | 06 Aug 2007 |
? As the object is moved from infinity towards the lens, the size of the image increases
? All the real images formed corresponding to different positions of the object is inverted.
? Only the virtual images are erect.
? The magnification of telescope depends upon the focal length of lens.
? The focal length of eyepiece should be small and objective should be high.
? If we use two convex lenses the image should be inverted.
? If we use one concave lens & other convex lens we get erect image.
? When
