  • This GPA Calculator lets you determine how your current term will affect your overall GPA. You can use it before you know your grades to predict your CGPA (Cumulative Grade Point Average). Due to the way this calculator is made, it won't calculate grade replacement if you are repeating a course. GPA Calculator will include both failing and new grades.
  • Fraction Calculator name speaks for itself. This piece of software will help you to add, subtract, multiply and divide fractions. Enter fraction #1 and fraction #2. Make sure you use / between numerator and denominator (e.g. 1/3 for one third). Select what operation you want to perform and click Calculate Fraction button to see result.
  • This tool lets you converter roman numerals to traditional numbers, and traditional numbers to roman numerals. A smaller number in front of a larger number means subtraction, all else means addition. For example, IV means 4, VI means 6.You would not put more than one smaller number in front of a larger number to subtract. For example, IIV would not mean 3.
  • Quadratic equation has the form ax2 + bx + c = 0. It will generally have two solutions; that is, two different values of x that make the equation true. It can happen that both solutions are the same number, and it is possible that the solutions will be complex or imaginary numbers. To use this software, type in values for a, b, and c in the boxes below, and press the Solve for X button.
  • It is not difficult to learn how to calculate the percentage of one number vs. another number. All you have to do is divide one number by another number. Then, then take that number and move the decimal place two spaces to the right. This way you will get your percentage. Percentage calculator lets you do all calculations quickly.

  • DRAGSENS Geo Software is used for the exact position estimation of a towed body, sensor, camera, array or net, dragged behind a ship, aircraft or vehicle. The software allows a real-time estimation of the position of a dragged sensor based on the location of a GPS-receiver. The sensor thereby can be dragged underwater, at water or earth surface or be airborne.
  • Pulse shaping filter program that finds the pole-zero locations of a transfer function, H(s), for a matched filter. H(s) equals a -desired- signal (Yout) divided by a given input signal (Yin). Both Yout and Yin are functions of frequency. Group delay may also be calculated to compliment a given data set, thus, providing a flat group delay. This is a Fortran Calculus demo application.
  • The calculation is developed for geometrical designs of belt and chain transmissions with more sprocket wheels (max. 15).
