Where can i find the blocks of feedforward system?
Hi,
I would like to create a feedforward system. However from what i've learn in a feedforward system i'll need a gain, deadtime and lead-lag block, where can i find these 3 blocks? i'm using LB8.2 and in the example finder i can only find 1 example, which is "Control Loop (with VFF and AFF).lvporg" but i cant open it due to missing parts. Are there any other examples that i can use as references? A simple and basic form of a feedfroward system.
With Regards
Wormwood
Look at the example: Simulation - Cascade and Feedforward Surge Tank Level.vi that comes with LabVIEW Real-Time or with the PID Control Toolkit.
Here is the picture if you want to see the controller implemented in LabVIEW. The Feedforward is a Lead-Lag block. Hope this helps

Where can I find the EAS log in System 9.3.1?
Does anyone know where I can find the EAS server log for 9.3.1? We recently would get an "EAS not responding" message intermittently. We would then close EAS then re-open and everything is back to normal, but after a few hours, this happens again.
Did you check your application server's log? systemout.log I believe it's called. That should show the activity on the App Server side.

VarunaThe LOAD command instruction is 0xE8 and not 0xE0/0xE1.
Lc is one byte, so how can you exceed FF?
Optionally the LOAD response can include a receipt (delegated management). If your card mandates a response length of 1 byte (Le=01) it means that no receipt is expected --> receipt length 00. JCOPs LOAD command has Le=0x00 set by default --> response length undefined. This is in accordance with Java Card API, which follows the ISO 7816-4 APDU structure.
Let's look at the help of the JCOP tools upload command:usage: upload [-p|--progress][-c|--components][-r|--random][-l|--package package-name][-s|--sd SD-AID][-m|--params parameters][-b|--block_length length][-a|--auto][-d|--load-debug] CAP-file
-c|--components
Load CAP-file component wise.
-r|--random
Load with random APDU length.
-b|--block_length length
Max. block (APDU) length sent to the card during package upload.
length Max. block (APDU) length.So you can set the block length --> Lc as you wish.

Where can I find the way to hide this TOOLTIP?
Hello everyone!
My name is Inspire.
I have got a trouble with Dreamweaver cc 2014.
Where can I find the way to hide this TOOLTIP? The Dreamwaver's CSS tooltip.
I would like to say this tooltip is a TERRIBLE design. It BLOCKED my vision.Edit > Preferences > Code Hints.
You can change default preferences for code hints. For example, if you don’t want to show CSS property names or Spry code hints, you can deselect them in code hints preferences. You can also set preferences for code hint delay time and closing tags.
Even if code hints are disabled, you can still display a pop-up hint in Code view by pressing Control+Spacebar.

launch your safari browser, then, on the top left corner of your desk top, enter into Safari browser preferences, then click on the security tab after your Safari preference pane pops up. once you click on Security, you'll see 5 boxes. the fourth one down will be the block pop up windows. unclick that puppy, and you'll be allowing pop ups. hope this helps.

Where can I find the accurate definitions of these terms?
Where can I find the accurate definitions of these Coherence terms?
Nodes
Members
Partitions
Thank youHi qkc (or shall I call you Frank?),
a node is exactly the same as a member: it is a building block of a TCMP cluster, a set of Java threads running Coherence clustered services and having a member id in the TCMP cluster. Usually a JVM has only once cluster node and therefore the entire JVM is referred to as a cluster node.
Let's for the moment define the following two terms: cache-partition and service-partition.
A service-partition is a unit of data management in a partitioned (distributed) cache service. The ownership of the entire content of a service-partition moves always together between storage-enabled nodes (upon rebalancing the cluster), whatever happens, regardless of nodes die or join the cluster. A service-partition has a partition id between zero (included) and partition-count (excluded).
A cache is another unit of data management, it is practically a beefed up map looking the same from the entire cluster. A cache service is a collection of several caches. Each cache belongs only to a single cache service, the one which is specified by the service-name element of the cache scheme referred to from the cache-mapping with the corresponding cache-name.
All caches in a partitioned cache services are partitioned to partition-count parts (let's call them cache-partitions), numbered again from zero (included) and partition-count (excluded).
All cache-partitions with the same partition id together form the service-partition. Again, ownership of these cache-partitions of the same partition-id always move together.
You will not find the cache-partition or service-partition terms in the documentation. The documentation uses partition both for cache-partitions and for service-partitions.
Best regards,

Fire Fox sent not all the data in text form. Reached only piece of information. Where can I find the cache sent the text?
For example, I posted an article on a news site, but found that only a small part of my article was posted.I'm not sure whether Firefox saved that information. There is a chance that it is in the session history file, especially if you haven't closed that tab yet. To check that:
Open your currently active Firefox settings folder (AKA your Firefox profile folder) using
Help > Troubleshooting Information > "Show Folder" button
Find all files starting with the name sessionstore and copy them to a safe working location (e.g., your documents folder). In order to read a .js file, it is useful to rename it to a .txt file. Or you could drag it to Wordpad or your favorite word processing software.
The script will look somewhat like gibberish, but if you search for a word in your article that doesn't normally appear in web pages, you may be able to find your data.
Any luck?
For the future, you might want to consider this add-on, although I don't know how long it saves data after you submit a form: [https://addons.mozilla.org/en-US/firefox/addon/lazarus-form-recovery/]. -
Where can I find the app "password Saver" by yonglin wang? while updating my iphone the app was dropped for some reason. I went to reload from my purchased apps and it is not available. The history shows my purchase but I can not find the app to reload. I've lost some critical info and need to retreive if possible. Any suggestions?
You tried what ? If the app is no longer available in the store (can you find it in the main part of the store ?) for re-downloading then you would need to have a copy of it somewhere e.g. on your computer's iTunes, on a backup of your downloads.

The link to system requirements for Firefox 4 beta takes you to a page that gives you the requirements for Firefox 3.6 instead. I assume that the requirements for the beta are different as I can't seem to install the beta on my Macs. Where can I find the beta system requirements?
I never expected Mozilla to neglect the users of Apple's PowerPC (PPC) computers, while still supporting much older operating environments such as Windows XP. So, I should just throw away a $6,000 system, which is still fast and functional, and contribute masses of heavy metals to land-fills because…?
I'm hurt and confused after supporting Firefox for many years — installing and using it not only on my own computers but on most of my customers' computers. Now I have to tell my customers with PPC Macs they can't have a secure cross-platform browsing experience from Mozilla. They'll have to learn to use some other browser, or buy a new computer.
If one doesn't buy a new computer every year, one doesn't deserve Firefox 4. This is sort of sounding more like a Microsoft™© doctrine. (But wait, I can still have Firefox 4 on a ''SERIOUSLY CRAPPY WINDBLOWS XP pile of rubbish?!'') Please open your eyes Mozilla. This just doesn't make sense. -

I rented a movie on Itunes last night and I watched half of it before falling asleep. Today I tried to open the movie and watch the last half but I cannot find it. It has been less than 24 hours since I rented it. Where can I find the movie?
I found my answer in another Thread and it worked... so for anyone who needs it, here it is:
https://discussions.apple.com/message/19134562#19134562
Had the same problem and spoke with Apple Support. They had me reset the System Management Controller:
Shut down the computer. With the computer off, on the left hand side of the keyboard press shift+control+option along with the power button simultaneously and release. Wait 5-10 seconds and restart the computer.
This solved my problem and I was immediately able to purchase, download, and play an HD movie from iTunes w/o any error message. -
Where can I find the no-no list?
As I am learning more and more about app development, it seems a lot of time can be wasted if you don't follow the rules Apple has set forth. I find post here and there about what not to do, such as using private API's, and tried searching in the Dev Center for something. As I learn I want to learn the, your app has more chance of not being rejected way, where can I find the "no-no" list Apple has?
The obvious document would be the App Store Review Guidelines for iOS and OSX.
iOS: https://developer.apple.com/app-store/review/guidelines/
Mac (OSX): https://developer.apple.com/app-store/review/guidelines/mac/
Note that iOS apps can only be distributed via the App Store while OSX apps can be distributed directly by the developer.
Creating a non-App Store app in OSX has several advantages and disadvantages:
The App Store handles a number of practical issues for you: like setting up a download page and processing payments. It also (supposedly) gives you access to a larger customer base and is the "default" location for getting apps that Apple pushes new users to. The App Store is also more convenient when re-downloading apps, safer and more convenient as users don't have to keep track of activation codes for purchased apps.
You don't need to sandbox your app, this is helpful for certain apps that need to access data from other apps or needed to call other apps e.g. via AppleScript.
You can use private APIs, although this is generally not recommended as these classes are not documented and may change/disappear between OS releases. But poking around in private APIs and other internals may sometimes be the only way to access certain information or to get certain features.
Not being a App Store app will also mean that you can't use certain APIs - I think that iCloud is one of these. -

When I click "about this mac" to check on my storage, I get a number of different sections music, movies, etc. but also I get a section called backups, where can I find the files in this section?
Welcome to Apple Support Communities
All the storage in "Backups" is taken up by local snapshots, which are made automatically in all MacBooks, MacBooks Pro and MacBooks Air with OS X Lion or newer and Time Machine turned on.
See > http://pondini.org/TM/30.html I recommend you to leave them there, because they will be removed automatically. However, if you want, you can disable or remove them manually if you want, even if there's no reason to do this. Have a look at the link above for more information -
I'm running 10.6.8 Snow Leopard fine on my MacPro1,1, Dual-Core Intel Xeon, 2.66 GHz Mac, but I need to install Lion 10.7.0 to run a program I need.How do I install OS 10.7 NOT 10.7.5, because I get this message when I try to install 10.7.5, which I've downloaded:"This update requires Mac OS X version 10.7." on a mac running Snow Leopard 10.6.8, So i need to install the original 10.7.0 over the 10.6.8 i.e. where can I find the original install app for Lion OS 10.7.0? The original Lion 10.7. is not avaialable for purchase from the App store or anywhere, even C-Net . Where can I find it to purchase?
Also it seems I cannot install Mountain Lion over 10.6.8 as advertised. When I go to purchase I get this message: "We could not complete your purchase. OS X Mountain Lion is not compatible with this computer." I think my computer can handle it (specs above) Are there any workarounds to this?If you're getting a "This update requires Mac OS X version 10.7" message, than you have the updater and not the full installer. Go to your Purchases section of the Mac App Store and you should see the full version there. But it may be 10.7.5, though in my system is shows as being from 2011 which would appear to be the original version.
As to Mountain Lion, that's supported only on the Early 2008 Mac Pro or newer.
Regards.
