Binary Definition and 569 Threads

I'm having trouble conceptualizing the variables involved with this system, and I was wondering if some expertise might make the problem much simpler than I believe it to be. Two massive spherical bodies (Osmium, minimum radius 900km, 5.08m/s^2 surface gravity) orbit each other with a solid or...

If someone could explain some of the steps needed to work out these 2 questions it would be much appreciated!

Typically in problems involving binary classification (i.e. radar detection, medical testing), one will try to find a binary classification scheme that minimizes the total probability of error. For example, consider a radar detection system where a signal is corrupted with noise, so that if the...

If I have program X how do I get it in binary form?

The following question came up when me and a friend of mine were discussing some basic things about probability:Let $p$ be a real number in $[0,1]$. Does there exist a sequence $(x_1, x_2, x_3, \ldots)$ with each $x_i$ being either $0$ or $1$, such that $$ \lim_{n\to \infty} \frac{f(n)}{n} =p...

What does the metric matrix look like for a binary star system? Does each follow its usual geodesic about the other? It seems like the solution would have to be different somehow than that for a tiny planet circling a big sun.

So I am in my Intro to CS course and they are going over Binary searches via an algorithm to search for simple things. The code goes as this: Set first to 0 Set last to length-1 Set found to FALSE WHILE (first <= last AND NOT found) Set middle to (first+last)/2 IF...

Hi guys! I'm new to the forum, i hope you can help me with this trouble! it really is important =D i have a 2D binary compound AB (made of one of the 100 family of planes of a rocksalt structure) and i am asked to "consider a single s-orbital on each atom (atomic energies Ea,Eb) and nearest...

I was thinking about the motion of two stars in a binary star system, but there is something I cannot quite figure out. Suppose you have a binary star system with two stars masses m1 and m2 with m2>m1 so that m2 is closer to the centre of mass of the system. Then when the two stars are as far...

Good night! Please, what happens to an object (eg a spaceship) placed exactly in the center of mass of a binary star system (composed by two similar stars)? Would it be compressed by a huge gravitational mass (something like the mass of both stars)? Would it be stretched and torn? Or would it...

Can someone explain why the probability of the inclination angle of a binary system being less than i_0 is 1-cos(i_0) i.e. why the fractional distribution of binary stars is df = sini * di, where i is the inclination angle? Where does the sin i come from? Why is not not uniformly distributed...

I am looking for books that explain the binary (stars or black holes or whatever) systems in a good (introductory if possible) and/or extensive way... Thanks :)

I have to read a binary file into a byte array and chop it wherever I like. I'd like to use a vector of char to do this. But reading some resources from known people, I find they tend to use char* or char []. Using a vector of chars seems easier for retrieval of any block of bytes. Which means...

Draw a Binary Search Trees (BST) produced when data containing 30,40,50,60,10,20,55,15 is inserted one by one. Thanks.

Forgive the broadness of the question. I know this is a huge concept which entire books have been written about. I am an amateur computer programmer entering my first object-oriented class soon and want to get some things out of the way. When I write lines of code how does the computer know what...

Hi! (Nerd) Given a tree, I want to write an algorithm, that deletes from each node, from the corresponding ordered binary tree, the rightmost child, that is a leaf. That's what I have tried: Algorithm(NODE *P){ if (P==NULL) return error; if (P->RC!=NULL) P=P->RC; if (P->LC!=NULL)...

Hi! (Wave) I want to write an algorithm, that counts the sum of the keys of the nodes of a binary tree, without the use of globals and statics. That's what I have tried: S(NODE *P){ if (P==NULL) return 0; int m=P->data+S(P->left); int n=m+S(P->right); return n; Could you tell me if it...

Hi! (Wave) How can we find the depth of a perfect binary tree and how of a complete one? (Thinking) Since a perfect binary tree is a full binary tree, at which the leaves have the same depth, I thought that we can find the depth, by just looking at the leftmost nodes, like that...
