Pseudo random numbers are right at hand in VBA. Obtaining truly random numbers, however, requires an external source. One is the Swiss Quantis QRNG Chip. The output from one of these has been made public by ETH Zürich, and here we present a complete solution for retrieval of random numbers in VBA.
Most of us live by Coffee. However, are you disguising the flavor of cheap store-bought grounds (or worse, k-cups) with chemical-induced creamers? There is a much better option, and it is easier than you think!
Whether you are designing precision imaging systems, high frequency electronic system, or other high speed system, simulation tools are a critical for designing, analyzing, and validating the functionality of your circuits for use in your next PCB.
There is no single "correct" calculation method for quartiles. Excel features two methods, some math and statistic packages offer some more, but here is presented no less than twenty methods for various purposes using VBA and Microsoft Access.
We can all agree that as we get older, intricate math equations slowly slip away and so it never hurts to go online for a little help. There are a few websites that offer free and comprehensive explanations that can be utilized by K-12, college students, teachers, and parents.
Usually, rounding is performed by some power of 10 - to thousands, hundreds, tens, or integer - or to one, two, or more decimals. But rounding can also be done to a power of two, say, 16 or 64, or 1/32 or 1/1024, even for extreme values.
There's never been a better time to become a computer scientist. Employment growth in the field is expected to reach 22% overall by 2020, and if you want to get in on the action, it’s a good idea to think about at least minoring in computer science and knowing how to code.
Aerodynamic noise is the cause of the majority of the noise produced by helicopters. The inordinate amount of noise helicopters produce is a major problem in the both a military and civilian setting.
