when I scroll in 1.1.6, Lyx crashes
I just changed to 1.1.6 on linux. When I try to scroll down in my document Lyx crashes and I get the following message: Sorry, you have found a bug in LyX. If possible, please read 'Known bugs' under the Help menu and then send us a full bug report. Thanks! Bye. I can view the whole document with the postcript viewer and view the whole thing, but when I try to view more than the first page in Lyx, it crashes. I can send the document without the images if you want to look at it... This is very frustrating because I thought that this was going to take care of a different problem (which it didn't). Now I cannot even edit the file!! Help! Anna

no figure files when I use multicol.sty
I am using 1.1.5fix2 on linux. PLEASE HELP!! I needed to get my abstract to go across the page and the rest of the paper to be a two column paper so I was told to use, multicol.sty...which works beautifully, EXCEPT that when I use it NONE of my figures appear in my postscript file!? What is happening? My tables are fine. When I take out the commands for the multicols, my figures reappear. Do I need to do something extra? Is this a bug just with Lyx and figures and multicol? I can't believe that no one has never needed to do this before? Anna

bugs?
I am using lyx 1.1.5fix2 on linux. I have two questions that I have asked the users list, that I don't know if they are bugs or just cannot be done... 1) documentpagestyleempty gets rid of all of the page numbers except for page 1. Is there some way to get rid of that...does 1.1.6 take care of that? 2) I am writing a paper with two columns, but I need for the abstract to be centered across the top. Is there any way to do that??

floating images within a page
I am running Lyx version 1.1.5fix2 on Linux. I know that this isn't the appropriate list to send questions, but everytime I send a question to the users list, I either get no repsonse or a somewhat incorrect response. On the other hand, you guys seem to be really sharp and on top of it all...If you don't have time for this...don't worry about it. I will continue to try to figure it out myself. My problem is this. I have say, nine images of which I would like to float three each to a page. (I know that they will fit.) Right now, when I do it, I might get four or two to a page, and I want exactly three. Is there a way to do that using the float figure command? Anna

figure collapse and automatic numbering
I am using lyx on 1.1.5fix2 on Linux (pc). I have a question about the floating figure. When I take a figure and use float and put in a caption, I don't have any problem, however, I was hoping to use it without a caption and just be able to use automatic figure labeling...ie. Figure 1, Figure 2,etc. When I collapse the figure in the Lyx window and then uncollapse it, I no longer have the automatic figure labeling ...ie. Figure 1, etc. Is this a bug, or am I doing something incorrect? I sent this to the help list and someone there got the same thing as myself. For now, I am just putting in a period, but it looks a little tacky. I know that I could just not collapse the figures...but I don't trust myself to never do that in the whole time that I am working on my paper. Is there a way around this...or as I said, am I just doing something incorrect? Anna

reference numbers turn to question marks
I am using a pc running linix with lyx 1.1.5fix2.
When I put in a file like the one I've enclosed and try to save it as
post-script, all of the reference numbers turn to question marks. Could you try
this on your system to see if it also happens with you? I've never had this
happen before, and I have no idea what I have changed to make it that way. Any
ideas would be greatly appreciated...as my coworker wants to switch to Microsoft
Word to write our paper!! Yikes!

Background

Metrics based on frequency analysis are currently used on vibration data
to detect faults from gearboxes
\begin_inset LatexCommand \cite{8}
\end_inset
.
These methods have been shown to find faults
\begin_inset LatexCommand \cite{12}
\end_inset
.
Frequency methods give global information about the signal.
In Health and Usage Monitoring Systems (HUMS), it is critical to determine
as soon as possible when a fault has occurred so that corrective actions
can be taken.
In standard Fourier analysis, a signal is decomposed into individual frequencie
s.
Unfortunately, there is no way to determine at what point in time each
of those frequencies has occurred.
However, there are signal processing methods which give local information
about both time and frequency.
These methods localize faults in time and therefore may be more sensitive
to early changes in the signal due to impending faults.
Some of these methods have been studied by other researchers
\begin_inset LatexCommand \cite{1,10,11}
\end_inset
.

In this paper, five methods of time-frequency (TF) analysis will be discussed:
the Short Time Fourier Transform (STFT)
\begin_inset LatexCommand \cite{2}
\end_inset
, the Choi-Williamson method
\begin_inset LatexCommand \cite{1,9}
\end_inset
, Instantaneous frequency
\begin_inset LatexCommand \cite{5}
\end_inset
, the Nelson method of cross-spectral analysis
\begin_inset LatexCommand \cite{6,7}
\end_inset
, and the Wavelet transform
\begin_inset LatexCommand \cite{2}
\end_inset
.
In comparing these methods, the following will be included: the assumptions,
resources, resolution, speed of calculation, resulting information, invertibili
ty and a ranking of importance.
\layout Standard
There are two important data sets that have been obtained and which will
be used to compare the methods.
The first data set was obtained from an OH-58A transmission on a test-rig
\begin_inset LatexCommand \cite{3}
\end_inset
.
It consists of 146 records where torque, bending force and lifting force
are varied in a controlled experiment.
No teeth were notched in the gear.
This data serves as a baseline and shall be referred to as the phase1a
data.The second is a set of 449 records of vibration data from a gear with
19 teeth in which 9 teeth were innitially notched.
The experiment was run until all 9 teeth broke.
This shall be referred to as the historical data.
Before this paper is completed, a third set of data from the same group
as in
\begin_inset LatexCommand \cite{3}
\end_inset
will be taken.
An OH-58A test-rig with a single notched tooth will be tested until rupture.
These data will be useful in obtaining information about the study of HUMS.

save to latex and then back to lyx
I'm not sure if you know this already...but, when I export a file from lyx to
latex and then try to read it back into lyx, the whole system completely
crashes. I've done this in the past so that I could add some latex sort of
things...I know that the idea of lyx is that you should never have to deal with
latexbut, well...
I'm using a pc with linux using lyx version 1.1.5fix2. I had this problem with
1.1.4, but the whole window system did not crash before...I just got some
unexpected results.
Am I not doing something right? I'm guessing that these are not perfect
inverses of each other?
I've enclosed my file in case it is particular to something that I am doing.

These methods localize faults in time and therefore may be more sensitive
to early changes in the signal due to impending faults.
Some of these methods have been studied by other researchers

In this paper, five methods of time-frequency (TF) analysis will be discussed:
the Short Time Fourier Transform (STFT)
\begin_inset LatexCommand \cite{2}
\end_inset
, the Choi-Williamson method
\begin_inset LatexCommand \cite{1,9}
\end_inset
, Instantaneous frequency
\begin_inset LatexCommand \cite{5}
\end_inset
, the Nelson method of cross-spectral analysis
\begin_inset LatexCommand \cite{6,7}
\end_inset
, and the Wavelet transform
\begin_inset LatexCommand \cite{2}
\end_inset
.
In comparing these methods, the following will be included: the assumptions,
resources, resolution, speed of calculation, resulting information, invertibili
ty and a ranking of importance.

There are two important data sets that have been obtained and which will
be used to compare the methods.
The first data set was obtained from an OH-58A transmission on a test-rig
\begin_inset LatexCommand \cite{3}
\end_inset
.
It consists of 146 records where torque, bending force and lifting force
are varied in a controlled experiment.
No teeth were notched in the gear.
This data serves as a baseline and shall be referred to as the phase1a
data.The second is a set of 449 records of vibration data from a gear with
19 teeth in which 9 teeth were innitially notched.
The experiment was run until all 9 teeth broke.
This shall be referred to as the historical data.
Before this paper is completed, a third set of data from the same group
as in
\begin_inset LatexCommand \cite{3}
\end_inset
will be taken.
An OH-58A test-rig with a single notched tooth will be tested until rupture.
These data will be useful in obtaining information about the study of HUMS.
