Hello Samir,

Could you explain me what this circuit couldn't be simulated if I replace the default fluid properties to the water's ones? The default fluid is an hydraulic oil, but for water (density = 998 kg/m^3, bulk coefficient = 2.2 10^9 Pa and cinematic viscosity = 10^-6 m^2/s) the simulation gives unsuccessful results. I tried with several solver with similar results.

Moreover, similar behaviours I experimented if I include chamber components into the hydraulic circuits.

sendtomap1.mw, sendtomap2.mw, wood_riess.zipHi! I've written a program for my work to obtain "chi square" for a range of data. Can someone tell me why my first example which I have attached and I've called it "sendtomap1" works correctly, but the second one "sendtomap2" has an error?...

Hello!

I'm writting a simple program to obtain chi-squared for my model. I've written it for a costant value of "n" and it correctly works and results chi-squared, but when I want to write a loop for "n" then the program doesn't work at all.

I don't recieve any error message. can you help me?

 

 

I am trying to create a certain visual effect in a Maple document / worksheet.

Basically, I have a small table with colored cells that I want to embed in a worksheet with an altogether different fill color. This sounds simple enough, but it appears that Maple's tables don't allow this.

I built the shock model in MapleSim

model

then I got the response accleration

result

For this curve, I want to solve its fourier series in Maple.

Do it work?

thinks in advance.

this is the msim file

how do i use Maple to prove a+c is congruent to b+d mod n?

Hi

I'm exporting arrays of plots as html (so I get multiple gif files). At the moment I do this off the menus (file\export as) is there a way to write this command at the prompt in worksheet mode?

thanks

  1. How do I 
  2. Write a maple program to calculate the probability that k cards in 3-dimensonal set game (out of 27 cards) contain a set for k=3…9.

      3  randomly generate 12 cards in 4-dimensonal set game, either find a set or report “no set”.

Im building a series of Java applets. My applets have text areas where students will write answers to questions. I am looking for a way to make my text areas be MathML boxes. Anotherwords, instead of adding the answer in normal text (1/2) it will be in Maple format. (1/2) should be a fractions, and not just a string as you see in this post.

Can I solve the following two coupled differential equations instead of the previous one in Maple 13?

 with plots

Eq[1]:=3*f(eta)*(diff(f(eta), `$`(eta, 2)))-2*(diff(f(eta), eta))^2+3*g(eta)

Eq[2]:=(diff(g(eta), `$`(eta, 2)))/Pr+f(eta)*(diff(g(eta), eta))

BCs := [f(0), (D(f))(0), g(0)-1, g(25)]

pars := {Pr = 1}

for i to 2 do eq[i] := subs(pars, Eq[i]) end do

eqs := eq[1], eq[2]

vars := f(eta), g(eta)

No that way I could have chosen infinity at 10 or lower values also. f ' will go from 0 to 0 through positive values only. But how can I claim then that my solution is infinity independent. Because if I change the value of infinity whole solution changes.

 

Moreover at 15.6 the value of f ' is sufficiently close to 0 but value of g (0) is about 0.15 which is far greater than 0. g (0) goes to zero at about eta=25.

So  can I get rid of the problem?  

I apologize for revisiting this question many months later. What I meant with the example was not diagonalizing but congruence. For a field that is not characteristic 2, a symmetric matrix is congruent to a diagonal matrix.

with(LinearAlgebra[Modular]);

A:=Matrix([[2,2,2],[2,0,1],[2,1,0]]);

C:=Matrix([[1,0,0],[2,1,0],[1,1,1]]);

CC:=Transpose(3,C);

C.A.CC mod 3;

The output is Diag(2,1,0)

The invariant in this case is 2...

Is there a way to insert a table of content with the headers of the sections at the beginning of the document? (like in MS Word)

If I click on the link, maple should jump to the section.

It should be updated, if I create a new section or change the header.

My operating system is Mac OS X 10.6.4.   Lately Maple has been EXTREMELY tempermental in letting me "Save As a Worksheet"......I'm NOT talking about the "classic worksheet"

 

I try to save a file with a different name using "Save As A Worksheet" and Maple goes through the whole "Saving Worksheet" routine BUT NO NEW NAMED file is made!

This is very frustrating.....since it wasn't like this before.

Any ideas?

 

Jim
