How does PWM contol Inverter that is connected to the grid? How do we decide the V refference?

I understand that when inverter change DC voltage(ex:PV voltage) to AC voltage, we need to condition the frequency and voltage to be the same level as the grid. We can use PWM for this. I study...

Is the $1000 VGA card worth to buy for MD and docking simulation ?

Our colleague suggests that, by bought the $1000 VGA card to our computer, our simulation would run incredibly faster, and can easily achieve 100 ns MD simulation in less than a week even though...

How do you determine events as good quality only from catalog data (when the waveform data is not available)?

I attach the catalog data header to make things clear. From this catalog data I want to specifically relocate every 'good' events using hypoDD at a certain depth target (let say 2-4 kms below datum).

What is your perception on using visual analysis or quantitative approaches to evaluate data from single-case research designs (n of 1 trials)?

Results of single-case research designs (i.e., n-of-1 trials) are often evaluated by visually inspecting the time-series graph and computing quantitative indices. A question our research team is...
