Homework Statement I have the next integral: \int\frac{dx}{x*arcsin(a/x)} between g0 and R2, assuming that R2,g0>0 and R2>x>g0 I'm using MAPLE but it seams that the problem is not the software, can you assist me to understand why is MAPLE unable to solve the integral. I've tryed to add...

Hi, we did a preliminary experiment to see if this will succes, we took a laser pointer, pointed through the bottom of the tunnel upwards, on top of the tunel laid an A4 sheet, the motion of the laser beam was captured with a video camera 30fps which was set above the A4 sheet. After some...

Hi, I need help or any sudgestions with the next scenario - I'm designing a sensor for a wind wave tunnel - can be found in the google search using the key words 'wind wave flume' The sensor should give me the speed and frequency of the cappilary gravity waves created in the tunnel by a...

Ryleigh lenght Thanks, now, if I condense a beam by 10 times it will reduse the ryleigh length and depth of focus by 100 times, what should I do to prevent it?

Hi all, I'm a student at a mechanical engineering faculty, and I'm doing my final project now. The purpose of the project is to built a sensor for measuring gravity-capillary waves in a wind-wave flume. The idea is to pass a laser beam from beneath of the aquarium through the aquarium...
