There are expressions of two kinds about how to calculate the magnetic force accelerating the projectile in coilguns. However, the inductance gradient expression had been quoted incorrectly by many researchers. It is necessary to demonstrate them correctly and prove their equivalent relation. In this ...

Salomaa (1966) gave two complete proof systems for proving that two regular expressions are equivalent ("identical"). If you can't access the link above, there is a description in Kozen's lecture notes. Kozen himself gave another complete proof system. As mentioned above, it is PSPACE-comple...
We analytically demonstrated that for this model, there is a threshold in the primary response level, r1*>0.5, that depends on the other parameters, at which the two strategies are equivalent. If r1<r1*, then the two dose strategy is always better, but, if r1>r1* vaccinating twice as ...

So, the sets are similar and these are equivalent. Conclusion In this chapter, we explained the concept of equivalence of regular expressions and described three methods to prove it. Generating strings can be tedious; identities make the process easier for complex regular expressions. Constructing an...
(TQE) seminars, both of which are analyzed using qualitative content analysis. The results show that most students adopt disciplinary conventions, such as building on each other’s ideas, using critical lenses, showing contextual awareness, and supporting claims with textual evidence. While the ...
