Please ignore my previous reply.
I accidentally got linked with this forum instead of C#.
Apologies for the inconvinience caused.

Correct - but you don't get far in physics without math, and without physics math is just an intellectual excercise, you draw the line between them, I suspect it won't be a straight one!! (probably a fractal)

I want to make my project (witch I did it with Matlab) I want to make it runs on any PC without the need of Matlab program to be on this PC.
in other words...I want to make my project an (.exe) file.
how can I do that please???

You will have to buy the MatLab compiler.

Check if "mcc" command works in your Matlab console.

I didnt understand
I wrote help mcc on my matlab command window....
I read what is written....
but how can I convert a matlab project to .exe file that dosent need matlab program to run...
note: I'm using matlab 6.5 or 7

you could ask in the matlab forums or help discussion.

mcc -m main.m
where main.m is the starting function (Entry point)of the project.
An exe file named "main.exe" will be created
along with other files and folders.
For further details google
with "mcc option for matlab".
Hope that helps you.

Can anyone tell me what kind of algorithm Tomtom and Garmin are using to find the shortest route in a huge data set as all roads on a continent?
Is it A*? In this case do they query the database in each loop?
Hope you understand what i mean.

usually commercial vendors use private, often patented algorithms for these things. This keeps the competition from directly redoing what they have done and selling it for less.

any easy and fast data mining algorithm any one knows?

To do what? There are a multitude of data mining algorithms each offering benifits in specific areas. You need to be more specific about what you are trying to accomplish.

Actually i have a huge data given to me and i have to identify let say all students name, address, reg.no, who belong to electrical engineering. what else pattern means, and i want to know the names of DM algorithm. also which one i can use more quickly and fast to understand as well as effective in limited time span.

Which interprocess synchonization mechanism is used for the DuplicateHandle Windows API function?
What is the necessity to have the handle duplicated if it points to the same object? Is there not a way to reference the same object through another means?
|
|
|
|
|
You can duplicate the HANDLE with different security attributes. You can use it to conjure up an inheritable HANDLE from a non-inheritable one and vice versa. You can use it to make the HANDLE valid in the context of another process.

I have four equations:
s = e^0.245t (t = time(sec) over 10 seconds) s = distance(metres)
s = 4.2ln(t + 1.2)
s = 0.2t(t-5.1)
s = 0.2t(t-5.1)(t-9.1)
and for each equation I need to find the displacement,velocity, acceleration, start postition and how long each takes to reach 10 metres away from it's starting point.
I know that:
Velocity is: ds/dt
Acceleration is :dv/dt
I have no problem finding the Velocity and acceleration:
1.
s = e^0.245t (Is this the displacement?)
Velocity = .245 e^.245t
Acceleration = (.245)^2 e^.245t
2.
s = 4.2ln(t + 1.2) (Is this the displacement?)
Velocity = 4.2* (1/t +1.2)
Acceleration = -4.2 (t+1.2)^-2
3.
s = 0.2t(t-5.1) (Is this the displacement?)
Velocity= 0.2t^2 - 1.0t (is this right?)
Acceleration = 0.4t-1.02
4.
s = 0.2t(t-5.1)(t-9.1) (Is this the displacement?)
=-(0.2t^2 - 1.02t)(t-9.1)
=0.2t^3 - 1.82t^2 - 1.02t^2 + 9.282t
=0.2t^3 - 2.84t^2 +9.282t
Is this the velocity?
Velocity =.6t^2 - 5.68t + 9.282
Is this the acceleration?
Acceleration = 1.2t-5.68
Now here's the question, how do I find the starting position that each equation starts at, and how do i find how long it took the equation to finish.
Thanks for any help!
If you need me to explain something better please ask.
Ps: Sorry for the long question.

so you are given s=f(t) and you are asked to find the starting position and the time taken to travel 10m. I think you should review your lecture notes one more time and figure it out for yourself. Look at some example that the lecturer did and see where the starting position is, and how to work out how far something travelled.

Suppose you have a function describing position of a particle in meters at a time:
f(t) = e^(3t^2)
Then, as you say, the first and second derivatives will be the position:
v(t) = 6 t e ^(3t^2) and
a(t) = 6 e ^ (3t^2) + 36 t ^2 e ^ (3t^2).
To see how displacement works, plug in some values:
f(0) = 1m
f(.5) = 6.351m
f(1) = 120.513m
So in the first .5 seconds, the particle is at position 6.351m, but since it started at position 1m, it has only traveled a distance of 5.351m.
I don't want to give it away, so I won't say more, but that should give you an idea of how to figure out the problem.
