Hello fellow mathematicians/computer-scientists!
I have a question:
If a subset of a language is not context free, does that mean the language itself is not context-free?
For example, I want to show that the following is not context free, using the pumping lemma:
L = {\omega \in...
what is the lim sup of the set containing all rationals in the closed interval [0,1] ?
and what is the lim inf?
How do I prove that the value is correct?
Hello
I am attempting to make a total pressure tube/probe to use on small scale wind tunnel testing.
Like a pitot static probe, this total pressure probe has to have a 90 degree bend like an L shape.
I have several copper tubes of around 3 mm OD.
I tried bending them by heating the...
Hello
I am undergoing a similar experiment at university and I am making an L shaped simple pitot tube (not pitot static tube). Are there any limits on the dimensions? Such as the ratio of the length of the base to the diameter of the tube? I have done research but cannot seem to find anywhere...
