WARRNING REGARDING Support from 2n.cz !!!!
Just a warring for everybody regarding this company.
I emailed 2n.cz to buy 2 gateways to integrate 3g network and GSM with my
asterisk box. They emailed me back to contact the local dealer for them. So
I did and I bought the 3G analog gateway (bought from the local dealer) and
BLUEVoice gateway(I bought it from a dealer in Serbia when I was there for a

mdct explanation
...;t have access to TeX, X, or anything else from a text terminal
with gcc and vi right now).
Hope you like it,

Suppose we want to calculate a MDCT (encode side):
(x_ is input (time) samples, w_ is window, b_ is output (freq) samples):
b_k = \sum_{j=0}^{4N-1} x_j w_j \cos{(2k+1)(2j+1-2N) \over 8N} \pi
After setting
a_j := w_{-j-1+N} x{-j-1+N} + w_{j+N} x{j+N}, j < N
a_j := w_{j-1-N} x{j-1-N} - w_{j+3N} x{j+3N}, otherwise
(or something similar; the cos'es should agree)
we get
b_k = \sum_{j=0}^{2N-1} a_j \cos{(2k+1)(2j+1) \over 8N} \pi
This is a DCT-IV.

Questions about 2n dc and samba update
Hi,
Thanks for your information about DNS config.
About second server and update, I understand that First I have to
transfer role to new added, demote old, and then rejoin and transfer
fsmo roles to source server, right?
My question is related with demote and transfer FSMO roles, this task
are stable and works correct? I'm not clear to demote main server, now
with 4.4.5 because no rolback

openssh 2n advisory
Hello
Well the openssh discussion is a little confusing.
http://www.openssh.com/txt/buffer.adv you can find a 2nd revision of the Advisory.
It includes also a patch for channels.c. Will this patch also be commited for the freebsd security branch or port?

How to calculate the index "the number of species combinations"?
...the index
because my english is not good.
The concept:
*The number of species combinations *This index scans the columns of the
presence-absence matrix and keeps track of the number of unique species
combinations that are represented in different sites. For an assemblage of n
species, there are 2n possible species combinations, including the
combination of no species being present (Pielou and Pielou 1968). In most
real matrices, the number of sites (= columns) is usually substantially less
than 2n, which places an upper bound on the number of species combinations
that can be found in both th...

query: sample size calculation
Dear all,
I am doing something wrong.
I am trying to apply a formula for sample size calculation as in the book
"Design and Analysis of Clinical Trials", from Chow et all.
There a suggested sample size strategy uses the formula
0.30/0.45=F(0.80,2n,2n)/F(0.025,2n,2n)
which gives n=96, as in the book.
(here F(alfa,k,n) is the upper (alfa)th quantile of an F distribution with
k,n degrees of freedom)
I have been trying to get n=96 using the following code in R.
val<-rep(NA,200)
for (n in 1:200) {
val[n]<- qf(0.8, 2*n, 2*n,lower.tail...

Hello!

The topic of the project is "Hermite Interpolation" and a I have allready done a script that finds the approximation in a certan point x, H(x) ~f(x) but i want to find the value of his derivative H'(x)~f'(x) as well and to do this I need the polynomial form of H(x)=a1*x^(2n+1) + a2*x^(2n) + ... + an but R requires x to be a value not a declared variable. Then I want to find the derivative of this polynomial and evaluate it.
So my point is how can I built a function f(x)=x^+x+1 and do its derivate dipending on x.

Classification tree data structure
Hi there,
I am growing classification trees using the 'tree' package add-on to R.
I would like to convert the 'R' output to the SAS format used by Salford Systems' commercial CART software in order to interface with some
other software.
My question is:
How can I parse the R tree data structure in order to infer the tree structure? The 'tree' class has a member

Questions about 2n dc and samba update
Hi,
I have to upgrade 2 different samba AD DC (2 domains) from 4.4.5 to 4.10.7
First is a single server and updaded with in-place upgrade from 4.4.5
to 4.10.7 and all perfect
Second environment I need to add a second dc and also upgrade existing
server, and I have some question about how to do this:

Randomization tests, grouped data
The other day I was looking into one of the classics in resampling,
Eugene Edgington's "Randomization Tests". This type of test is simple
to do in R with things like a simple correlation, the sample ()
function is perfect for the purpose.
However, things are more complex if you have grouped data, like a
one-way ANOVA. The reason is that you have to avoid the consideration
