Hi everybody, We all know that we can have random numbers by pressing #RAN or #RND button in calculators and there is such a command in computer programming languages that produces a random number. It's always been a question for me that how does a computer or a calc generate random numbers? Does it have a certain algorithm or sth?

The reasons we have the particular layout we have today are out-dated and irrelevant for today's use on computers, as the original design was modeled for use on a keyboard. would it be effiecient or beneficial to change the standard QWERTY keyboard layout?

I want to clarify my simple understanding about the role of ALU. There are two components; 1- Arithmatic Unit. 2- Logic Unit. The role of arithmatic unit is simply to do arithmatic operations on numbers. These numbers come from written program instructions. The role of Logic Unit is to derive logical conclusion. It performs comparisons to decide about equal, greater or less values etc. The thing I want to clarify is that logic unit derives logical conclusions. Just like in ordinary deductive logic, there are two premises and the conclusion is drawn from the information contained in premises. My question is that is computer also derive deductive conclu…

Hello, I cant understand how to proof cook's theorem. Especially, i cant undertand proof on book of Computers and Intractability. Please help me about how to understand simply this proof. best regards...

Will the Semantic Web ever be successful? For those who don't know, the Semantic Web, pioneered by Tim Berners-Lee himself, is an attempt to move the web from a loosely structured collection of documents to a type of machine-understandable knowledge structures called ontologies. To put it simply, the Semantic Web tries to add meaning to the link structure of the web. It's like what the Xanadu project was trying to do way back in 1960, although they were waaay ahead of their time, and some worry the Semantic Web might be too. So far, no one has managed to make a "killer app" for the Semantic Web's underlying technologies, but this may be in the pipe in the form of Sema…

Will it happen primarily via hardware or software? Why?

Okay, not really, but this is sure a big step forward in intelligence research: http://numenta.com/ Numenta, a startup company founded by On Intelligence author and Redwood Neuroscience Founder Jeff Hawkins has released both binaries and source code for their general intelligence algorithm, known as Hierarchical Temporal Memory. This software is based on the behavior of hierarchical networks of neocortical columns in the brain, which Hawkins theorizes provide the foundational components of human consciousness.

The solution to this problem is not very hard : you just use a combination of two kinds of technique You use a combination of search and non search , the idea is to limit the search to a managable level, a clever technique of limiting the search by using a convex hull is applied, and you do partition the search space in to a set of layered convex hulls where the computation to find the optimisation is done one step at a time, please see my algorithm description : or just type NEW ALGORITHM FOR THE TSP in youtube search

Hi all! I am studying Master of Computer Science. I am interesting in Astronomy and want to study about Astronomy. I don't know if there is any topics which combine Computer Science and Astronomy. My major is Machine Learning, Data Mining, Rough Set Theory... I hope I can find out a suitable topic which relates to Astronomy and make it become a good thesis in Computer Science. Please help me.

Hi there, my Friends. here, i'd like to discuss the possible & the best techniques for subj. 1st & foremost, i would like to share my humble approach to protect buffers. code: https://sourceforge.net/projects/dasofi description: http://alg0z.blogspot.ru/2014/10/dabofi.html perhaps, description seems too short, but i hope code is more verbose ====================== Thanks a lot in Advance for your contribution.

Many renowned scientists believe this event is all but inevitable and that the consequences of it are so far reaching that it will change our World profoundly. We will be living in the post human era if we manage to survive at all. Others argue it will go a very long ways in solving mankind`s most difficult problems and may even lead to human immortality. This event is predicted by many to occur within 5 to 30 years. Many of these scientists I am refering to are some of the most res…

I was thinking... can every object in the world be described 100% acurately in bianary, theoreticaly i mean.

Okay guys, I need some help. I know some C++, about enough to fit in one semester. When I took the course we covered a little bit passed arrays. Anyway, I never really understood how to make an actual application. We would write some code maybe about 300 lines at times, and we would run the code or some of you might call it "debug" and this is where the command prompt would pop up -- usually it would ask me to input some values to calculate whatever my code was intended to do. However, I never really learned how to make an application where you can actually interact with and do other things. What I mean by that is for example all the applications that you find in your mob…

prove the formula: (111*)* = (11 + 111)* thank you for helping

Hi all, I am doin masters and studying Theroy of Computation.I have my final paper after few days and i m facing some serious problem regarding exercises of Theroy of Computation book "Sipser - Introduction to the theory of computation - 2nd EId".I tried to search the sol on internet but didnt find it anywhere.Plz help me if anyone can provide me with the sol or with the link where i can get help regarding exercise quiestions.Some of the exercise questions are solved while some are not.I am writing few of the questions which r troubling me.Please if anyone can give me the sol of these. 1) Let INFINITE PDA = {<M>,M is a PDA and L(M) is an infinite language}…

hello guys consider the following production rules A->Bb A->a B->Cc B->b C->Aa C->c I think the above grammar has indirect left recursion I need an equivalent grammar which is not left recursive

I have put many of my thoughts about OS design into this document. I appoligise in advance as some of the document contains OO programing jargon. Feedback is welcome. http://with-logic.co.uk/docs/TheOSProblem.docx

there are software to simulate and predict the biochemical pathways of the enzymes that control the cell cycle (control points) during mitosis?

I am pursuing my ME.I want some help for my thesis.can anybody tell me is suffix tree tree can be applicable to find longest common subsequence...

can u help me in looking my thesis topics in the field of information technology??? pls post it as soon as possible...

Hello, I am currently a first-year transfer student at a state university, with two years military intelligence experience. I am currently considering becoming a computer science major. I'm posting this topic to start a discussion, and take as much advice regarding classes/internships etc. I am an extremely motivated person, and will give my all at anything I do, all advice and criticism will be responded to respectfully. Thanks

I’m living in the new house now! Several days after my wedding, the house still looks brand new. So I took some pictures before we mess the beautiful look. I’ll show you the pictures!

Yeah, obviously, "wow that looks dangerous" but, other than that, what do we think? http://www.download.com/P2P-Backup/3000-2242_4-10496612.html

Eventually, I think I want to work through programming my own OS Has anyone here done this?

I'm confused with the notations used in algorithm analysis. Can somebody compare and contrast "Big-Oh vs Big Omega vs Big-Theta" notations with respect to time Thank you......
