Does anyone know where I can find instructions on how to build high torque robotic servo. I have purchased the most powerful R/C servos available and need more torque and travel. So I'm looking at building my own from scratch. I basically need it to function like a regular R/C servo but with much more torque and travel and it needs to plug into a standard R/C receiver. Thanks, Kevin.
How to build robotic servo with standard Radio Controlled (R/C) interface?
There is a magazine I found at the Barnes %26amp; Nobel bookstore about making robots. It's called SERVO. It's a nice and informative magazine. My son totally enjoyed it.

Why isn't there a biginteger class in C++ standard libraries?
I know there are many third party extentions that allow big integer like in Java, but why isn't in the the standard libraries?
Why isn't there a biginteger class in C++ standard libraries?
If you don't count the STL as part of the core language, C++ libraries are pretty sparse. Many things are not included, BigInt support being the least of them. The core C++ language, like C is very thin.
Reply:The C++ standard libraries (C/C++ in general, really) are intended for fairly low-level application design.
Nothing prevents the implementation of an arbitrary length integer class, but the standard types of 64-bit ints (long long) and double precision floats (double) are sufficient for the vast majority of apps while still remaining very close to the hardware.

An investor holds a portfolio that comprises of 20% stock A, 30% stock B and 50% stock C. The standard deviations of returns on Stocks A, B and C are 22%, 15% and 10%, respectively, and the correlation between returns on each pair of securities is 0.6. Prepare a variance-covariance matrix for these three securities and use the matrix to calculate the variance and standard deviation of returns for the portfolio?
An investor holds a portfolio that comprises of 20% stock A, 30% stock B and 50% stock C. The standard deviat
y = (x'x)-1x'y + u
so you have three equations there.
since correlation is given = .6 i.e E(uu'), and you know the return, therefore you can calculate uu' and hence solve the three equation using cramer's rule...
sorry I cannot type in the matrix's here

C and C++ standard library?
Are the function implementations in the standard library already in object code or are they in source code that must be loaded before the compiler runs so that they can be compiled.
C and C++ standard library?
The standard libraries are created by only the object code. By the object code we can create our own header files also. It is for reducing our code complexity. For using the header files with our programmer, the object code is enough. and also for become to usage of header files only the object code is loaded. That's it.
Reply:Hi there. I'm not sure what you mean by "already in object code"... if by "object" you are referring to the executable file generated by the compiler and NOT the object-oriented version of "object", then the answer is no, because there before compiling, there IS no object file. If you mean the object-oriented version of "object", then I'm not even sure what your question means.
When you do a #include %26lt;insertlibraryhere%26gt;, you are telling the compiler to look for a library matching the name you provided, and to include the functions contained within that library in the compiled code. So the answer to the 2nd alternative you provide ("are they in source code that must be loaded before the compiler runs") is yes. After the compiler runs, you will have an executable object file that does include the standard library functions.
Reply:C++ standard library is very good
try to use that
Reply:Taher is clueless, TOB has no idea what he is talking about, and sridhar is hard to understand, but I think he has it right.
So, the standard library is precompiled into binary. Whenever you compile your program, you do NOT recompile the standard library source. Whoever made your compiler has compiled the C/C++ runtime libraries and various library files for the different aspects of the standard library. So whenever your code uses something in those libraries, they get appropriately linked in.

Regarding header files about ANSI/ISO C++ 97 standard.?
According ANSI/Iso C99 standard it includes 24-25 header files.I'm aware about all those header files and the functions in thsoe files. But i don't know ANSI/ISO C++ 97 standard contains how many header files.According go ANSI standard( Not related to any compiler specific.)Can any one of u provide a list of all ANSI/ISO C99 standard header files.And suggest me a compiler which supports this standard.If u know any book which explains functions in all these header files.

What string gauge would you suggest for c standard tuning?
i play guitar and this is the first time i have to play in a tuning below E And D
standard tuning
What gauge would be best for C
What string gauge would you suggest for c standard tuning?
a lot of it depends on how hard you play.
i play very aggressively, i guess, because i'm using 11's and only tune down 1/2 step - but my strings feel very "loose" and my strings can go out of tune within a few songs, especially when on stage. maybe it's just me?
you can play that low with 10's, i'm pretty sure, but you have to be very careful how you play - play softly, don't dig in too hard, that kind of thing.
me, i'd go up to 12's or 13's.
i'd probably have to. =)
make sure you get your guitar reintonated pretty quickly, cuz changing your string gauges that much will almost certainly require a change in the action and/or truss rod. if you can't do it yourself, take it to a guitar tech.

How do you tune you guitar in c-standard?
ive been playing for about 5 months, and my tuner is basic only has the basic letters e a d g b e, it doesn't have C or F so i dont know how to tune to c standard, can anyone help me out?
How do you tune you guitar in c-standard?
C G C G C E
* Start by tuning your sixth string down to full tones to C.
* Then tune your fifth string down a tone to G. Check the tuning with the third (G) string.
* Next, tune your fourth string down a tone to C. Check the tuning with the sixth (C) string.
* Lastly, tune your second string UP a semitone to C. Check the tuning with the fourth (C) string.
Reply:If you tune your guitar to the notes on your tuner (E A D G B E), you will be in "standard tuning".
Guitar is a "C treble" or "concert pitch" instrument, meaning that a when a guitarist plays a written C note, the note that actually sounds is a C.
In comparison, on a "transposing instrument", like a Bb clarinet, the player reads a C in the music, but the note that actually sounds is a Bb. Someone playing an F horn will read a C in the music but when they play it, the note that actually sounds is an F. Many, if not most, woodwinds and brass instruments are transposing instruments; most string instruments, including guitar are non-transposing (C or concert pitch) instruments.
So to tune your guitar in C-standard, you would simply need to be in standard (EADGBE) tuning and play the music as written.

How do i tune my guitar in C standard?
Tune the E string down, holding your finger on the 2nd fret, and it will become a C when the tuner reads D. F is the same principle. Hold down 4th fret of the 5th string (A) and when the tuner reads A, the string will be F.
Reply:Tuners are fine and dandy, but you have to develop your ear.
Once you have your E strings in tune, you can find an F note by placing your finger at the first fret.
You can find a C note by placing your finger at the first fret of the 2nd string B.
I've been playing for over 40 years, and I know nothing about 'Queens of the Stone Age,' and what possible tunings they use.
If you want to tune to open C, you'd have to tune each string to one of these 3 notes...
C, E, or G. I seriously doubt you need to tune to open C to play these songs...just use standard tuning and your ear.
There are solutions to everything on guitar and multiple chord forms that would fullfill any task.
It's also possible that this band tunes to Eb. Many bands prefer this over standard tuning.
If you search the tabs for these songs, you can find some that list alternate tunings, but again, this is not neccessary.
Use your ear, experiment...you'll progress far faster.
Good luck.

Ax+by=c (standard form of a line)?
I don't understand standard form. Could someone please tell me what the slope of a line would be (I know it's something over something...) and what the y-intercept would be? ...Like, in terms of a and b and c and x and y... yeah....?
Oh, and what do the x and y stand for? Are they just the x and y values of any given point on the line the equation is describing?
Thanks!
Ax+by=c (standard form of a line)?
The slope is the opposite of a/b
The y intercept is c/b
Example: 2x + 3y = 5
Slope= -2/3
Y int= 5/3
The x and y are just x and y values that are on the line.
Reply:Ax + By = C (Standard Form) can be put into y = mx + b (Slope-Intercept Form). You can do this by isolating the "y." The "ax" is slope and "c" is the y-intercept. I hope this helped. =]
Reply:The slope m, when converting from standard form is -a/b. The y-intercept is c/b. you can see this clearly by subtracting ax from both sides and dividing both sides by b.
