Std XI Sc. students,
Write programs using IF ... THEN ... ELSE and GOTO only (i.e. without SELECT CASE or FOR...NEXT)
- Prof. Anand is a greaaaat mathematician who is always in search for a particular kind of numbers. So he asks random people on the street to give a number and if they give one which does not satisfy the rules below, he chews their head off (NOT LITERALLY, but by giving a LOOOONG derivation as to how they are wrong). Now the professor has asked you to write a program for him, to save his time. (which he can use more productively to chew people's heads off) His rules are as follows:
- The number should be odd
- The number should be divisible by 7
- The number should be at least 3 digits long
- The servo controller program (one that controls the movement) for the GMRT telescopes has the logic given below. Write a code which will take the required inputs, take the required decision and message the decided action.
- Take the coordinates - Altitude and Azimuth - from the user, in order to point the dish to that direction in the sky
- If the angles show that the pointing would be below the horizon, then reject the input coordinates. This would be so if the altitude (measured from horizon upwards) is less than 0 degrees.
- If there is a strong wind (as measured by the wind vane, i.e. in our case inputted by the user at the start) i.e., above 40 kph, then ignore the input coordinates and park the dish (i.e., turn the dish to look exactly overhead, that way it is unaffected by the wind), i.e. set the coordinates to: Altitude - 90 deg, Azimuth - 0 deg
- If there is no strong wind and the coordinates are above the horizon, then point the dish to the inputted coordinates. (i.e. give the message to the user that it is doing so)
ALL Students - You should have deicided by now, exactly how will you perform your experiments for the P & C projects. You should know the apparatus needed and the procedure. You will get the first lab access in a day or two. From that moment we start marking you out of 30 Mks.
GMRT guys ... we continue work after 2pm
- Radio - The Cantenna "works" but catches not the sky or source, but rather my internet dongle. SO we need to recalc. We dont proceed with horn unless Cantenna works out
- Gravity - You could use the cloth and ball model to demonstrate the action of gravity (i.e. forming of orbits etc.) provided you make it at least 1m x 1m. Think on those lines. To prove Newton's law of Gravity, you would need to create a long but gradual slope (less than 10 deg with the horizontal) That way you get control on timing accuracy.
- Astro-Photometry - I need yor power calib today. You could simply use photoshop or any package to give you a relative value of intensity for the bright dots (images) as against the dark background. (values may be within 0 - 255) That way you get a calib for a known source.
- Colorimetry -
- Resonance -
