Hello, I am currently doing a 3rd year undergrad project on forward radio meteor scatter the problem involves the following: I have over 80Gbs worth of 10 second data blocks of recorded radio input. They are stored as date stamped .bin files in binary format, each of order 1700kb or...

Hi, I'm trying to prove that there's a bijection between the open interval (0,1) and the set of all sequences whose elements are 0 or 1 in order to show cardinality continuum. So let C={a1, a2, a3,...|ai is either 0 or 1} which is the set of all sequences of 0's and 1's and let...

Homework Statement How many different commutative binary operations can be defined on a set of 2 elements? On a set of 3 elements? The Attempt at a Solution I do not understand the question. Seems like an infinite number.

So I have really been struggling with this question. The original question said: The map \varphi:Z->Z defined by \varphi(n)=n+1 for n in Z is one to one and onto Z. For (Z, . ) onto (Z,*) (i am using . for usual multiplication) define * and show that * makes phi into an isomorphism. I know that...

Homework Statement 1) Let S be a set and p: SxS->S be a binary operation. If T is a subset of S, then T is closed under p if p: TxT->T. As an example let S = integers and T be even Integers, and p be ordinary addition. Under which operations +,-,*,/ is the set Q closed? Under which...

My first topic here. Here goes I've written a small program that first calculates pi in decimal and then changes it into binary. But as you know there's no accurate binary presentation even for 0.1 so I just can't change the whole 20000 decimal representation of pi into binary. I there for...

I can't figure out how to get these 2 methods to work. In my assignment description it says public BinTree getLTree() Get a reference to the left subtree. If this is not possible to do then throw an IllegalArgumentException. NOTE This routine returns a BinTree, not a Tnode. You...

I may be posting to the wrong forum, if so, please advise. I'm reading a book on rotational symmetry and its relationship to quantum mechanics. The author is talking about rotations of a unit sphere, in particular binary rotations, i.e. rotations of 180 degrees. He says "If a rotation [he...

hey i've been having trouble understanding a part in this question. i'll just map out the basics to the question: 2 stars with a velocity of 220km/s are orbiting at equal distance. the masses of the stars are equal. period = 14.4 days it asks to find the mass of each star. i understand that...

This is more of general question, but i am working on a project that involves binary stars. Basically, i am capturing data through a telescope, and i was wondering if i had all the parameters, how could i project, or calculate the motion of a binary star in terms of speed and direction. Any...

I don’t get how a http://www1.eere.energy.gov/geothermal/powerplants.html#binarycycle" keeps the fluid flowing in one direction. My guess is it has something to do (1) with the condenser and (2) with a pump thrown in. The problem with a pump is that it must use up as much energy as the heat puts...

The internal path length of a full binary tree is the sum, taken over all internal nodes of the tree, of the depth of each node. Likewise, the external path length is the sum, taken over all leaves of the tree, of the depth of each leaf. Consider a full binary tree with n internal nodes...
