Some population ecology:

Are all r-selected species semelparous, and all K-selected species iteroparous?

Also, can someone explain the process of polyploidy-driven sympatric speciation in plants?

Honestly, it will be a pleasant surprise to get a good answer from this, but it's worth a shot.

Merci

I'm stuck with this one here:
[Image: 1192416175.Dot.png]

This is a NFA automat, which isn't deterministic. It's my task to make a DFA (deterministic) automat from the power set of this NFA, which outputs the same combinations...

Any idea? Either my self-constructed automat misses combinations or it has too much... darn thingy.

I could take a jab at it in a few hours, seeing as I'll be on a train, but do check if JFLAP can't help you out.

I can't believe it.:crazy:JFLAP did it! This monstrous DFA had 15 nodes... one of the rare cases, where the deterministic automat is bigger then the NFA.

Thanks Knuthetal!

Actually, it's the other way around with the sizes, usually.

That'll be...

Any idea of a Push-Down-Automat, which created twice as much 'a' as 'b' ?

:huh:

Anyways, I'm available to help people now that I'm out for summer break now. As long as it's not whatever that stuff ^^^ up there is.

Somebody understands double integrals on area and finding gradients of function?
And in all Linear algebra?


Discovery Homework Help Kiosk! - Seth Karlo - 06-23-2009

Yes, I do Maths.

State the question:)

How to find double integral on the set area and threefold integral on the set body? For example: SSdxdy on area D set by functions y^2=4x+4 and x+y=2. Explain what is gradient and a derivative on direction and how to search them, it is desirable with examples
