Waveform accidentally scaled before PSD, how to undo?

Before passing the waveform to Power Spectral Density VI, it was divided by 1000. I am getting my PSD output in dB.
How could I undo the effect of the division? Is there any factor to scale by?
The PSD used is the standard Labview VI, with all default values (except with dB on).

Someone else many come along that's a lot more familiar with the underlying math, but I'm pretty sure you're hosed.
The lesson that you need to learn here is: always, Always, ALWAYS save the raw data -- then after the analysis save the results in a different file. And backup everything.

I just downloaded Yosemite and all my iPhotos have disappeared! I tried importing them from the photo library but it said there wasn't enough space on my hard drive which is rubbish, because they were there before. How do I get them back to iPhoto?

There are 9 different versions of iPhoto and they run on 9 different versions of the Operating System. The tricks and tips for dealing with issues vary depending on the version of iPhoto and the version of the OS. So to get help you need to give as much information as you can. Include things like:
- What version of iPhoto.
- What version of the Operating System.
- Details. As full a description of the problem as you can. For example, if you have a problem with exporting, then explain by describing how you are trying to export, and so on.
- History: Is this going on long? Has anything been installed or deleted? - Are there error messages?
- What steps have you tried already to solve the issue.
- Anything unusual about your set up? Or how you use iPhoto?
Anything else you can think of that might help someone understand the problem you have.

Browser keeps opening with previous tabs from day before. How do I stop this?

Under Tools>Options>General I have the browser set when I open the browser to "open up a blank page" but it keeps opening up previous tabs from the day before. How can I stop this? I read the forum boards but either did not find it or overlooked the answer. I checked all my other settings and cannot find anything that would be causing this. Please advise?

You can check if you have a user.js file in the Firefox profile folder that sets the browser.sessionstore.resume_session_once pref to true.

After restoring my iPod it went back to its factory conditions and i got iOS 4.2.1 which i have never had before? how can i get it back to my normal one or how can i get iOS 5 as on the apple website nothing is telling me to how to download it? can i please get some feed back so i know what to do.
Also the touchscreen isnt intime as quick as it used to be after I restored it, This is quite annoying whist im playing a game on my iPod. Thanks:)

Are you sure you really have a 3G iPod? A 2G iPod can only go to iOS 4.2.1. When you restore an iPOd wyou will get the latest iOS.
You need iTunes 10.5.X for iOS 5.
If your iPod is a 8 or 16 GB one it is a 2G iPod. Apple only made 32 and 64 GB 3G iPods. A 32 GB one can be either. To tell a 2G fom a 3G ypy need to know the model numbe engraved on the back see:

I wrote 6 pages in a document. I wanted to put page 4 before page 3 and could not move them. They had a box around 5 pages and I don't know how I did that, nor do I know how to undo that.

And you guessed wrongly.
On my side, I guess that before opening the menu, you clicked somewhere out of the pages (in the thumbnails areas for instance).
Re try after cliking at the bottom of a page.
The feature is really described in Pages User Guide.

My question is to anyone that can help..I downloaded 2-300 photos on my iPad and want to reload a few hundred more. The last time I did this I lost the first batch of photos I loaded a week before. How do I just add without losing what is already on iPad?

You need to add the new photos to the ones that are currently on the iPad and (re-)sync them all - only the most recent photo sync remains on the iPad, not including photos in a subsequent sync is how you delete them from the iPad (as you've found out).
You can use third-party apps such as Simple Transfer which can copy photos to the Photos app via your wifi network, but they will only go into the Saved Photos/Camera Roll album, and not into a 'proper' album.

I have problem with my contacts. I can't send message if the contact didn't send me a message before. How can I add new address?

Hi tizac,
You will want to add them to your Contacts.
There's a "+" button at the bottom of the contact list on the left to add a contact.
If you need to add the email address or phone number to an existing contact, there's an Edit button at the bottom of the contact info (on the right).
Once you have the contact email address or phone number you want to message to, scroll all the way down to the bottom of their information and there are options to:
Send Message               FaceTime
Share Contact             Add to Favorites
Of course choose "Send Message" to send an iMessage to them and you will start a new chat. You will be given the options of how to contact them, via phone number (if they are on an iPhone) or email (if they are on an iPod touch or iPad).   They do need to be signed up for iMessage or it won't allow you to send.

Spam has greatly increased in my inbox. It was not a problem before. How can this be improved? Is anyone else having this problem?

What mail program are you using??? Who's your provider???
You can usually log in to your account and make changes to spam filtering, server side.
Client side you can add spam filtering software like SpamSieve. Very effective.

Hi,
Your best bet at this point then is to contact iTunes Support and get them to straighten this out for you:
https://expresslane.apple.com/Issues.action
Select the options that best apply to your issue. You will have a chance to provide a written description before you submit. iTunes Support will get back to you via email, usually within 24 hours. Be sure to check your Junk/Spam email folder if you don't hear back by then.
They should be able to sort it out for you...
Good luck!
Cheers,
