For hardware based method, you can use an independent timer to trigger off the counter to measure the number of speed pulses in a suitable frequency, such as 1MHz. In that case, the time interval you obtained is so small that it apporaches to zero.
Instantaneous Angular Speed (IAS) is investigated for last 10 years in Condition Monitoring. The content of IAS is coming from angular speed. If the time taken is reduced apporaching to zero, we can measure the angle travelled to extract IAS, or if the angle travelled is reduced to zero, we can measure the time elapsed to extract IAS.

The above was written for the interested layperson who wants to learn more about science. It provides some context for our manuscript that has recently appeared in Nature.
From Northwestern Engineering:
In a paper published July 26 in the journal Nature, researchers led by Rod Ruoff, John Evans Professor of Nanoengineering in the Robert R. McCormick School of Engineering and Applied Science, report on the development of "graphene oxide paper."
The thread for residual stress analysis, measurement
Here are some of my recent papers about mechanics of rubber material. They concern constitutive modelling, fatigue and fracture.
Hello,
Recently, I have a problem bothered me alot, anybody please help me out.
I am using Dimension 3100 AFM. It is a scanned tip SPM. There are two screws to adjust mirrow so that the laser can be reflected to the photodiode. My problem is:
Hi everyone. We're interested in analysis and design of
3D Panel
Wall & Roof Structural. You're welcome to join us.
This is either a wage question I am asking or a stupid one...
How many fracture criterion do we have and what are they? some of these criterion that I am reading are related or a form of others...For example CTOD (crack tip opening displacement) criterion is related to energy release rate in
" A CTOD-Based Mixed-Mode Fracture Criterion" by Fashang Ma et al.
Any guid or direct help would be much appreciated.
Thanks for your time
Arash
