This self-explanatory video demonstrates a machine learning principle on a hardware assembly. I was mostly engaged by this Arduino-LabVIEW project when the COVID-19 was creating rampage in Europe.
Magnetic circular dichroism is a measure of absorption coefficients difference between right and left circularly polarized lights that coming out of a magnetized sample. Here, it is demonstrated how to convert a V-VASE ellipsometer into a MCD measurement setup. A mechanical stage holding two ring magnets with micro-adjustment screws is attached to the Ellipsometer stage. For further enhancement of ellipsometer beam intensity, two lenses are used and metal pin detector from the ellipsometer source is removed. MCD result from a sample is presented in this video for the proof.
Wet etching process is a very hard to control process in the area of micro-fabrication. This tool was build to etch magneto-optic sample in heated phosphoric acid environment. The tool uses micro-controller circuit to run two stepper motors and a dc motor. Basically, stepper motors are used here to give transnational motion to the sample and dc motor provides the spin to the sample in the acid bath. Thus, uniform etching of the sample is achieved.
This video talks about developing some simple exercises to get rid of coronavirus infections. These habits are backed by scientific measurements and hence will help people to follow them. To keep the video short, I could not touch deep on the performance of these exercises, therefore, I urge interested personals to contact me via my email at [email protected]. Lastly, I dedicate this video to all my near and dear ones whom I lost recently.
