Binary Definition and 603 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...

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...

I am about to do a paper about distributing subjects to students with the constraints on: number of subjects that the student need, number of students whom these subjects will be distributed to, and the number of students that every subject can handle (for example, 50 for math 1 and so on)...

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...
