Is there a simple way to get Maple to convert x^(3/2) + x^(5/2) to (x+x^2)*x^(1/2). I am willing to assume(x>0). Maple does recognize these as being equal: > p:=x^(3/2)+x^(5/2): > q:=(x+x^2)*sqrt(x): > simplify(p-q); 0 Here's a clumsy way to do it: > p:=x^(3/2)+x^(5/2): > assume(t>0): > subs(x=t^2,p); > simplify(%,{t^2=x}); > collect(%,t); Is there something simpler?

Hi, any suggestion to make the integral of: Exp[-(x-m)^2/(2 s^2)] x (1+x^2)^-1 Exp[-(x-m)^2/(2 s^2)] x^2 (1+x^2)^-1 Exp[-(x-m)^2/(2 s^2)] x^3 (1+x^2)^-1 between -inf and +inf (or indefinite)? Look like it is not possible, but it is too long time I do not make integrals with more advanced techinques (as going to the complex plane)... so if you have suggestions (wonderful a solution :) )....

Hi Since the power is more relevant to analyze than the amplitude I have come = up with the idea of using signed square ss(x) =3D x^2 for positive x and -x= ^2 for negative x or ss(x) =3D (x^2)^(1/2)*x =3D sgn(x)*x^2 Instead of analyzing the power as the square of the amplitude the signed po= wer could be used instead. This would preserve more information of the orig= inal signal. The original amplitude signal can be recreated from the signed= square power signal with signed square root. I can imagine signed square to be applicable to codec evaluation and signal= compression since the power of the signal is more relevant to compress tha= n the amplitude. It would be easy to make a simple test with Scilab and some sound or image = file. Would it be possible to analyze this theoretically with Karhunen-Lo=E8ve th= eory?

May be the help for linspace should change? It says: "LINSPACE(X1, X2, N) generates N points between X1 and X2." Notice, it says BETWEEN. But when I ask for 2 points, between 2 and 2: ---------------- EDU>> linspace(2,2,2) ans = 2 2 --------------- May be mathematically this is ok? i.e. there are infinite points between the point and itself? (on the real line), but from programming point of view, it is confusing. no? --Nasser Maybe it should say "generates N points between X1 and X2, inclusive." What did you expect to get back as an answer from issuing linspace(2,2,2)? I didn't understand your statement "there are infinite points between the point and itself?" How do you have an infinite number of points between 2 and 2? I can see an infinite number of points between 2 and something that's not itself, like 2.00000000000000001, but if they are absolutely perfectly identical how are you getting an infinite number of points?

Hi , I hope this isn't too trivial to ask, but I'm evaluating a polynomial that involve lots of terms like x^2y^2z^3, and although I can use the power function pow(a, b), I wonder if just writing x*x*y*y*z*z*z for example wouldn't be more efficient than pow(x, 2)*pow(y, 2)*pow(z,3).

Set your QTDIR and KDEDIR environment variables, make sure you have an adequate version of Qt, and then compile arts, followed by kdelibs, and finally kdebase. Then, change your /usr/X11R6/lib/X11/xinit/xinitrc file to start 3.2 beta rather than 3.1. If it all works, uninstall all your old KDE RPMs. I have an old version of Mandrake that came with KDE 2.2.2 and upgrading to 3.1 and now to 3.2 was easy. It took me nearly a full day to compile everything, but the number of hitches were low. Great thanks! This will be a project for tomorrow. Geoff.

hi folks, i figured it out and wanted to give back to the community. to recap, i'm a little fast with the mouse and sometimes when clicking on an application button, kicker would ask me if i wanted to add something (as seen in my previous note.) to stop that from happening, i added [$i] as the first line at the top of .kde/share/config/kickerrc and restarted kde. now it's working great. jlg > hi folks, is there a way to lock the panel so that no changes can be > made to it accidentally? > > i dont know how i do it, but sometimes when i click on a button on the > panel, a small popup menu shows up saying: > "Add as a file manager URL" > "Add as a QuickBrowser" > the taskbar gets all scrunched up and one time i messed up my panel > since i didn't notice the popup until it was too late. > > one other way this affects me is when i use a kvm at work and the mouse > gets in some bad state where it makes the panel disappear (along with > all sorts of other havoc.) > > thanks in advance, > John > > jguerrero > > -at- > > live365 > > .d.ot. > > .co.m. > > ^--- thanks@in.advance hmmm, i spoke too soon it seems. i'm not sure why i didn't see this yesterday, but despite having [$i] at the top of kickerrc, i can still make changes to the panel (ie, back up kickerrc, copy a button, then diff against the backup.) interestingly, the new ...

Hello, All! There are some sources of pseudo network interface driver develkoped for 2.2.x kernel. I have to port it onto 2.4.x kernel. I have explored the structure 'net_device' from linux/net/netdevice.h, there are few major changes. The main problem for now is - how to check that interface is ready to transmit data (in 2.2.x 'tbusy' field was used fot this and function 'test_and_set_busy' checking the 'tbusy' state). But thus field was removed from 2.4.x kernel, and now you should use the function 'netif_start_queue' or 'netif_stop_queue'. How can I check in 2.4.x that device is not busy and ready to to transmit data? Thanks in advance. With best regards, Roman Mashak. E-mail: mrv@tusur.ru ...
