Looking for modal analysis software for ground vibration tests

I'm looking for Labview code or compiled program that will work with a NI/VXI data acquistion system and supports modal analysis of ground vibration test data on airplanes. Specifically, based on accelerometers, need to synthesize mode shapes; mode indicator function; stabilization diagram; damping estimation; mode animation; mode overlay (comparison); Modal Assurace Criteria (MAC); plotting.

LabVIEW and our dynamic signal acquisition products, particularly the NI 4472B have been used extensively for acquiring data from GVT on aircraft.
For conducting the analysis that you describe, there are several good solutions from some of our partners. These include MTS I-DEAS, m+p International Smart Office, and Vibrant Technology's ME'Scope. All of these packages directly support the NI 4472B as a front end. MTS recently delivered a system to KARI for a high channel count GVT test that used the NI 4472B as the front end.
MTS is developing a new package based on LabVIEW for doing this type of testing, but won't be available until sometime later.

I am looking for Modal Analysis Labview VI lib or example?

I am looking for Modal Analysis Labview VI lib? specifically, I conducted Frequency Response Measurements, I managed to construct the experimental frequency response function. Now, I am looking for modal extraction from the experimentally determined frequency response function.
I appreciate if someone knows about Labview VI or example to perform the curve fitting in the frequency domain to extract the modal parameters.
Thank you in advance.
Atef T. Massoud

Atef,
I found the following paragraph in the on-line description of the Advanced Signal Processing Toolset for LabVIEW:
<>
"You can also construct your own custom applications in LabVIEW with a VI library of the most efficient and common algorithms such as covariance, principle component auto-regression (PCAR), Prony's method, and the matrix-pencil method. Some of these methods have not been commercially available before the release of this toolset. Using these VIs, you can perform both super-resolution analysis and modal-analysis. Moreover, VIs provided can easily be tailored for many other signal analysis applications, such as system identification and linear prediction."
It seems as if this set of tools might
help you with your application.
I hope this suggestion gets you pointed in the right direction. Have a pleasant weekend.

Any recommendations for a recovery software for my lost photos on my external drive?

Would like recommendations for a reputable recovery software for my lost photos from my external drive that I used with my MacBook Pro.

General File Recovery
If you stop using the drive it's possible to recover deleted files that have not been overwritten by using recovery software such as Data Rescue II, File Salvage or TechTool Pro. Each of the preceding come on bootable CDs to enable usage without risk of writing more data to the hard drive. Two free alternatives are Disk Drill and TestDisk. Look for them and demos at MacUpdate or CNET Downloads.
The longer the hard drive remains in use and data are written to it, the greater the risk your deleted files will be overwritten.
Also visit The XLab FAQs and read the FAQ on Data Recovery.

Installation error message for Oracle Database software for version 10g

Would someone be able to advise why I keep getting the following error message whilst installing Oracle trial Database software for version 10g Release 2 Standard Edition, Standard Edition One, and Enterprise Edition? Link listed below : -
http://www.oracle.com/technology/software/products/database/oracle10g/index.html
Error message "Cannot create directory"C:\oracle\product\10.2.0\db_7\cfgtoollogs\dbca\projemp"
Below is the 12 steps that I go through, please advise what I'm doing wrong : -
1. (Operations) default is Create a database
2. (Database templetes) default is general purpose
3. (Database Identification) projemp.local for Global database name & projemp for SID
4. (Management options) default is "Configure the database with Enterprise manager, also the options button has been clicked for "Use database control for database management"
5. (Database Credentials) the options button has been clicked for "Use the same password for all accounts" so I've set up a new password, was that correct?
6. (Storage options) the options button is clicked for "File System - use the file system for database storage.
7. (Database file locations) the options button is clicked for "Use database file locations for template" Is this option correct? Other options are Use common location for all database files or use Oracle-managed files?
8. (Recovery configuration) the options button is clicked for "Specify flash recovery area
9. (Database content) nothing has been selected, the only option is "Sample schemas" should that be clicked?
10. (Initialization parameters) the options button is clicked for "Typical- allocate memory as a % of the total physical memory
11. (Database storage) no options available
12. (Creation options) the options button has been selected for "Create Database"
Click finish
I then get a screen stating General purpose, click OK then I get the following error message as stated at the start of this e-mail ""Cannot create directory"C:\oracle\product\10.2.0\db_7\cfgtoollogs\dbca\projemp".
Regards
Phil

I've removed the software from my computer using control panel, programs & features then uninstall once but the other five times the software hasn't been listed. Whilst the Oracle was on my task bar I was able to install using Start > Programs > Oracle - HOME-NAME > Database Administration > Database Configuration Assistant.No you didn't. Database Configuration Assistant does not remove software. It can remove a database. As I mentioned before, there is a difference between the software and the objects that software manages. Deleting an Excel spreadsheet is not the same as deleting Microsoft Office. Deleting an Oracle database with Database configuration assistant is not the same as removing the Oracle software.

Now that oracle is not on my task bar I've unzipped the link below, clicked on db, Disk1, setup, changed the Database password (is that correct?) install and I get the following error message "Check complete. The overall result of this check is: Failed<<<<<
Problem: The install has detected that the primary IP address of the system is DHCP-assigned.
Recommendation: Oracle supports installations on systems with DHCP-assigned IP addresses;
However, before you can do this, you must configure the Microsoft LoopBack Adaptor to be the primary network adapter on the system. See the installation Guide for more details on installing the software on systems configured with DHCP."
So what did you do with the above error message? Did you follow up on what it said? Did you read the very fine Installation Guide that comes with the software? Did you read the section on networking considerations where it discussed DHCP assigned addresses and installing the loopback adapter?
http://www.oracle.com/technology/software/products/database/oracle10g/index.html
Ok, that link takes us to the download page, which does not shed any light at all on your problems
I'm using Windows Vista Home Premium, 32 bit operating system, and my computer is saying I have 142 GB free space.
If you read the installation manual that came with the downloaded software, you'd have seen in the prerequisites that Home editions of Windows are NOT listed as supported platforms, whereas Business, Enterprise, and Ultimate editions specifically ARE listed as supportd.
Hope this is some help.And
I'm not to clever on computers so would you be able to advise how I get to the command window to issue the SET command please?
Also I've no idea what OS user I am, I'm taking an on-line Oracle course and been advised to install "Oracle Database software for version 10g Release 2 Standard Edition, Standard Edition One, and Enterprise Edition"
How do I find out if I'm part of an Administrator, ORA_DBA group ?
Can you walk me through how to create the directory from command line please?Ok, given the above statements from you, I'm not even sure where to begin. I don't want to be cruel, but this self-admitted lack of even the most rudimentary knowledge by someone attempting to learn about Oracle is truly astounding. What course are you taking? Why are you taking this course?

Correlation and Principal Components Analysis software for Mac

Greetings-
I am looking for Mac software that will compute correlations between multiple variables and perform principal components analysis on the resulting intercorrelation matrix. These would be small data sets, 10 or 15 variables, 100 subjects. I have Excel which could be used for data entry. I Googled it and became glassy-eyed and may have missed the obvious. This is for personal use so I cannot afford large programs like SPSS which is a great program. If there is nothing runable on a Mac, are there packages on the net that one can use?
Thank you in advance, I appreciate your help.
Best,
Rich
Huntington Beach, CA

Hi Limnos-
Thanks for your response. Your links will be excellent for somebody! The first link concerns Principal Coordinates Analysis for Mac which is related to multidimensional scaling, potentially very valuable for someone looking for such a program. The second and third links provide lists of esoteric software statistical packages some of which for Mac which would be highly valuable for scientific and academic users. Sadly, they didn't provide what I was looking for. Still, all three links were excellent, thanks again.
Again, I seek a basic correlation package and a factor analysis or principal components package that is free or affordable. If it ran with Excel that would be a plus.
Thank you in advance,
Best,
Rich

Looking to purchase Nik software for Lightroom OR Photoshop. Is there a difference in the versions?

I currently use photoshop for all of my photo editing. I just purchased a copy of Lightroom though, which I plan on integrating into my workflow. I'm also looking to buy the complete collection of Nik software. If I want it to be compatible with photoshop, the complete collection is $200 more expensive. My question is are the versions of Nik software the exact same whether using it for Lightroom or Photoshop? What potential drawbacks are there for me not to be able to use Nik in photoshop, but only in lightroom?
Thanks!

The versions are similar but the photoshop version gives you the extra tools for, brushing, erase, fill and clear which to be honest i've never felt a great use for and if you duplicate the layer in photoshop before heading back to LR (to use NIK) you essentially get the same thing. Eg:
LR to photoshop as TIF or PSD
Duplicate layer
Save and back to Lightroom
Add NIK effect
Back to photoshop if you want to do any brushing or mask erasing of the nik plugin you applied in LR because you have the original layer underneith.
Even better if you think you can get away with all your editing in LR because you will always have the adjusted RAW alongside the TIF or PSD that Nik software will create anyway. I say save your money, a whole $250 now because the Lightroom version has been reduced again.
Ahh if only LR would give us layers........

Looking for real good software for iMac to encrypt all key strokes. Online a lot ! Thanks

Hi. Can anyone recommend software, free or not, that will encrypt all of my keystrokes for better protection while online?
User friendly, easy setup & maintenance.
Need ASAP
Thanks so much!

Was the friend, perchance, on a PC? "To understand how KeyScrambler works, it helps to look briefly at how an operating system like Windows actually processes keystroke data." - http://www.techrepublic.com/blog/security/keyscrambler-how-keystroke-encryption- works-to-thwart-keylogging-threats/4648
Do you have reason to suspect you have keylogging software running on your computer? If you do, you have a bigger general computer security issue because your security would be so lax you could have all kinds of things on it. I mean, we're talking you downloading malware left, right, and center from unscrupulous web sites and allowing them to install it on your computer. Basically a Mac equivalent of a PC user running their computer for the past 5 years without any virus protection. If things are that bad then you're famous because I have never heard of a Mac user who has things going to that extent. I'm not sure if I could do that to my computer if I even tried.

Looking for Solution Center software for my Office Jet Pro 8600 All-in-One

I have installed the Drivers and Full Feature Software in order to get Solution Center, so that I could scan multiple photos into individual files. It still does not appear as installed. I have an HP DV6-73680L laptop running Windows 8.1.
FYI, I loaded the software from the link below:
http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?softwareitem=bi-108858-3&cc=us&dlc=en&lc=en...

Maria,
Just checked again...
I do not know whether this will make a difference - I did find this:
HP Officejet Pro 8600 N911a Firmware
Note the description at the bottom of the page regarding the scanning feature. It is unlikely that the exact feature you seek is included. There are times that the description is somewhat lacking in detail.
Click the Kudos Thumbs-Up to show appreciation and say Thanks.
Although I strive to reflect HP's best practices, I do not work for HP.
Kind Regards,

I am looking for a POS software for multi-users with mobility via 3G and Wi-Fi

Our company distributes food products to grocery, convenient and pharmacy stores, etc. We currently have an old cumbersome hard to use PC system that interfaces with driver's handhelds, keeps records of sales and monitors inventories on trucks and several warehouses. All our company uses MAC systems with the exception of this PC system. The closest I've come to find a MAC software is Lightspeed but it lacks mobility. Does any one know a good reliable POS system with Mobility hopefully to utilize either iPhones with bar code readers?

Pages can export documents in MS Word format. When I last did this (with Pages '09, the Mac version), the result was a .doc file.
Note that this is a translation, and like most translations, it's not always a perfect one. Some features of Pages are not supported in MS Word, and some Word features are not supported in Pages.
For a more precise answer wrt Pages for iOS, you should repost your question in the iWork For iOS community. The link will take you there.
