How to calculate the rate of data transfer if I know that the total number of samples/s?
I'm looking to set a PXI system for measurement of County at high speed, routes, while that controlled remotely via MXI - 4. How can I be sure that the controller is capable of rapid data transfer quite seen the number of channels and frequencies of sampling provided?
I think I figured this out, but maybe someone can save me. For the task at hand, I will have a PXI-4496 and four PXI - 6143 s all 32768 samples/s sampling. 4496 is 24-bit, and 6143 is 16-bit. Thus,.
bits of samples/s/channel x 24 16 channels x 32768/8 = 1 048 576 bytes / s
+
32 x 32768 samples/s/channel x 16 bits/8 channels = 2,097152 bytes/sec
=
3 145 728 bytes/s, or exactly 3 MB/s.

How to calculate the total of a mathematical operation
Hello everyone,
I'm new to Essbase calculations, and I'm trying to figure out how to make a recurring calculation and store the results in a specific data point. I have two accounts:
Volume of sales (in units) - StoreData
Rate of work (hours) - DynamicCalc based on a specific percentage by product rate
These two pieces of information are by product. As each product has a different rate and volume, to calculate the total number of hours required for the production of all the elements, I have to do something like the calculation below where (sales volume * wage rate) for each product:
Total hours = SUM (sales volume * wage rate)
It is very easy to do in relational DB, but I need help with Essbase.
Any ideas? Thank you very much.
M.You try to do something of relationship in an OLAP cube. The way to proceed is different. In Essbase, you would make the Total number of hours of calculation = sales volume * wage rate) on each product and their aggregation up to the size to get a total at different levels.

Calculate the total number of the schema rowset.
Hi all
I use the oracle 10g database on windows server 2003.
I want to calculate the total number of lines in a pattern.
I have only one method to select just count (*) from each table within each schema.
because it doesn't matter what possible query that could calculate the total number of lines in a pattern?
Thank you.
Published by: Maahjoor on May 13, 2013 23:21Hello
Well, if you keep your cool failry statistics, you can get a very good grip on the number of lines through the NUM_ROWS in dba_tables column and then summarize the owner, on the top of my head:
select sum(NUM_ROWS) from dba_tables where owner like 'SCHEMA';
Do not forget that the number of lines shown this way will be the number of lines at the time of the last crawl (dbms_stats) has been run on the segment, so it may not always be equal to the number of the schema rowset did when running.

How to determine the total number of images in the external .swf file loaded
I have to be able to load both external .swf files and make them play in order. To do this, I need to know the number of images in the first .swf file so I can check _currentframe against _totalframes to determine when he is finished playing so that I can load another.
Most of the stuff I see indicate that _totalframes on an external .swf can be determined by loading the .swf in a container clip and then check using a listener in the .onLoadInit. Like this:
------------------------------------------------------------------------------------------ ----------------------------
this.createEmptyMovieClip ("tester_mc", 1);
var mcListener:Object = new Object();mcListener.onLoadInit = {function (target_mc:MovieClip)}
target_mc.onEnterFrame = function() {}
If (this ._currentframe > = this ._totalframes) {}
trace ("total frames =" + this ._totalframes);
delete this.onEnterFrame;
} else {}
trace (target_mc._currentframe + "OF" + target_mc._totalframes);
}
}
}var test_mc:MovieClipLoader = new MovieClipLoader();
test_mc. AddListener (mcListener);
test_mc.loadClip ("Ad_Group.swf", tester_mc);------------------------------------------------------------------------------------------ -------------------------------------
Unfortunately, this doesn't seem to work. The trace will always return a total number of frames of 1.
I guess it's because the container clip has only 1 frame, and the external .swf timeline seems to be ignored.
I would appreciate any ideas on how to raise the total number of frames of an external .swf file or, Alternatively, put it another way when it's done playing. (Not only the loading, but play until the end.)
TIA,
C
I guess it's because the container clip has only 1 frame, and the external .swf timeline seems to be ignored.
I wouldn't imagine. My guess is that the main scenario for the external swf file has only 1 frame and the rest of the animation is inside a movieclip in this timeline. You publish this swf? Can you open the FLA and check how many images is open on the main timeline?
The approach that you have mentioned is about what there is. But he knows check a chronology. If there are many nested movieclips, it may be impossible to understand what timeline you really want to be 'THE' full chronology.
If you have the FLA, you can have the video call function on the _root timeline which tells the main swf that has completed a movieclip or something like that.
Also, I have in my head somewhere that I recently saw something that someone made similar to this one, but do not remember... If it appears in my head that I will post.

Is there a way to get the total number of samples to a TDMS file?
I'm looking at the documentation for the function of properties Get TDMS and I see that it has a property: wf_samples which "represents the number of samples in the first data segment. Is it possible to get the number of samples in, say, the second segment of data? My goal is to get the number of samples in all segments of data for a single channel.
To retrieve the total number of samples, I use the properties of 'NI_ChannelLength' to be linked to the function of TDMS properties get.
The I64 outbut gives you the total number of samples of the selected channel.

How to calculate the Total price based on a rate of m² with different prices?
Hello
I'm guessing that it is a script, but I've never done any script so I would like to ask you guys...
I have a form where I would calculate the total price for some carpet based on the price per sqm.
-L the user enters the number of carpet needed.
-There are different price points for 1-20, 21-60, 61 + m² (each with their own hidden field that contains the value of awards).
-The Total Price field evaluates the relevant quantity and multiply by the square metre rate.
Is it achievable?
I guess that all solutions are placed in the "Custom calculation Script" field too?
Thanks in advance!
Yes. You can use something like this, as the custom of the price field calculation total (you may need to adjust the domain names):
var sqm = Number (this.getField("SQM").value);
rate of var = 0;
If (sqm > 0 & m²)<=20) rate="">=20)>
ElseIf (> 20 sqm & m²)<=60) rate="">=60)>
ElseIf (> 60 sqm) rate = Number (this.getField("Rate3").value);
M² = Event.Value * side;

Thank youTry this - http://www.pythian.com/news/29703/oracle-instance-memory-usage/ for each of your instances.
As far as I know, different instances may share only the binary code oracle and using libraries, so you should be able to easily understand the amount of memory of all instances of 12.

How to get the Total number of nodes XML?
Hi all
I have a Flash program that I do in Actionscript 3, using CS6.
I use the XMLSocket class to read XML data. I'll write some examples of XML that is sent to the Flash
program below...
I know with this line here (below) I can access the 4th 'element or node' of XML data.
To access the XML nodes/elements:
* I created a Variable XML, called xml, and "e.data" contains ALL the XML data
var XML = XML (e.data);Access to the 4th item of the data:
. xml MESSAGE[3].@VAR; -> 'loggedOutUsers '.
. xml MESSAGE[3].@TEXT; ---> "15"
EXAMPLE OF XML DATA:
< FRAME >
0 < VAR MESSAGE = "screen2Display" TEXT = "FRAME_1" / >
1 < VAR MESSAGE = "numUsers" TEXT = "27" / >
2 < VAR MESSAGE = "loggedInUsers" TEXT = "12" / >
3 < VAR MESSAGE = "loggedOutUsers" TEXT = "15" / >
4 < VAR MESSAGE = "admins" TEXT = "2" / >
< / FRAMEWORK >
I'm new to Flash and Actionscript but I am very familiar with other languages and how paintings and other work, and I know for
example, in a Shell Script to get the total number of items in an array called 'myArray' I wanted to write something like
This-> ${#myArray [@]}. And since the data processing XML looks a lot like a table I thought that there was perhaps
a way to access the total number of "nodes or elements" in the XML data...?
Any thoughts would be much appreciated!
Thanks in advance,
Matt
even if you don't need to run to the loop to know the length
var levelList: XMLList = xml.children ();
levelList.length (); This will give you the length of all children in your case of length MESSAGE of nodes;
Pls click useful if my answer is helpful.
Thank you

How to track the total number of downloads of my app BB10
Hello
I'm not sure of this is the right section to post in, but it's the best I could find.
I want to track the total number of downloads of my BB10 APP on the blackberry world. Download report is very simplistic and just generates a chart leaving me count manually. I tried also to export the data to download to Excel. While this works, it is a bit heavy. Is there another way for me to be able to view these data easily right now? Or do we have to wait for the SDK analytical tool to be made available for BB10?
Thank you

How to display the total number of rows in the dashboard
Hello
I have a dashboard report for retrieving the list of projects and details, it grows on a daily basis, instead of users downloading the report and find out the total number of projects, I want to display 'the total number of projects' alone in the dashboard. How can I do?
Also is it possible to do like a pop up or something a little flash news - not necessary, but will be very good if I can do it.
Thanks for your time and your help.create a report and a column to write a column invert the function max (rcount (1)). Call this column depending on the position of the column (as @1) in narrative mode.
You can view only the narrative in the dashboard.for flash type of report, you can use the ticker view and call the same column in the view.

In the workbench, I use a SetValue
Until you assemble the document that you need to build the DDX string and specify the xml information.
Concat (/process_data/@ddxHeadStr, "
AFTER mounting
Use SetValue that set your xmlinfo variable (xml type)

Then get your pages from the XMLinfo
