• Mapping the table matrix 2D

  I can't try to plot the graph of an output matrix, Sk since a MathScript node.

  The Sk parameter should be a way out of the matrix (12 x 1) with the length of the added step.  I can see that its fate in the form of a table 3D but can not get the graph of the function works.

  What I aim to do...

  I need to draw responses to the 12 line separate items of the Sk parameter over time.  This means that I have to post 12 separate parcels, ideally to be on the same graph with a shift on the value axis for stacking the answers (I'm not worried about the relative amplitudes since I was only interested in seeing the step responses in 12 plots).

  If someone can provide some guidance it would be greatly appreciated.

  Just right click on the tunnel exit SK and select data type "matrix of 1 d, DBL.

  (The way you slice the table at the beginning is crazy.) Why do you want to create all copies of these data for the most part redundant? Simply no autoindex on 2D and table use the table to index resized to five outings and wire the first clue to the final iteration to get five tables 1 d. You must also calculate the value connected to N for the number of columns minus four, or similar)

• design of table size question of data modeling

  Hi Experts,
  Sorry if I put my question in a wrong forum please suggest an appropriate forum.
  
  need your opinion on the current design of our data warehouse of 10 years.
  There is a dimension table with the structure as follows
  
  Dimension table
  --------------------
  Number of dimension key (THIS IS NOT a PRIMARY KEY)
  Natural key (from source) number
  the source name character
  current record indicator e Char (1)
  date of form_date
  TO_DATE date
  several other columns, which, if change a new current record is created and the previous one is marked as H-historical
  
  Data are stored in the table of size like this
  Dimension_key natural key Source name current record ind from_date to to_date
  1 10001 Source1: 1 January 2005 May 31, 2005
  1 10001 Source1: 1 - jun - 20005 12-dec-2011
  1 10001 Source1 C 13-dec-2011 NULL
  
  2 20002 Source1: 1 - jun - 20001 12-dec-2011
  2 20002 Source1 C 13-dec-2011 NULL
  
  The problem I see in this design is that if any attribute is changed there is no surrogate key, the new record is inserted first taking the key dimension based on the (natural_key, source_name, current_record_ind).
  Shouldn't it be kept as follows based on the principles of data warehousing.
  
  Dimension_key natural key Source name current record ind from_date to to_date
  1 10001 Source1: 1 January 2005 May 31, 2005
  2 10001 Source1: 1 - jun - 20005 12-dec-2011
  3 10001 Source1 C 13-dec-2011 NULL
  
  4-20002 Source1: 1 - jun - 20001 12-dec-2011
  5 20002 Source1 C 13-dec-2011 NULL
  
  Please let me know the advantages and disadvantages of the current design.

  Correct, your second example for example by using a surrogate key is design to go with.

  Flaws with the original design:

  -There is a relationship one between Dimension_Key and Natural_Key, no need to keep both.
  -Si Dimension_Key is the FK with a fact table, there will be a number of many relationships between fact and Dimension.
  -Additional processing to search for Dimension_Key rather than simply for example use a sequence.

• The number of tests table PCQ Questions

  Hi guys,.
  
  Where can I find (IOM 9.1.0.1 tables) the amount of questions of users trying to do?
  
  Thank you for your attention,
  Thiago Leoncio

  USR_PWD_RESET_ATTEMPTS_CTR

  It's exactly what you want.

  Just try and see its result.

  But once a successful connection it resets the counter.

  Suppose that you forgot your password and you want to change this password using PCQ.

  Now when you click on five-year plan link so if you gave wrong answer it then it increase the counter (USR_PWD_RESET_ATTEMPTS_CTR) to 1

  Assume that once again if you try with wrong answers it increase to counter (USR_PWD_RESET_ATTEMPTS_CTR) 2.

  But after a successful login, it resets the counter (USR_PWD_RESET_ATTEMPTS_CTR).

  USR_PWD_RESET_ATTEMPTS_CTR you can get a tent PCQ.

  For any other details, did you see System Configuration in the console design?

• creating a table/average question

  I'm new to labview and I have problems to understand how to create a table.

  I use an Arduino Uno as my DAQ and when I take an anolog measure I've seen a lot of fuctuation to my measure. I know with arduino, you can perform with an average simple by using the function "Get a finished sample of Analog", but I know that I not be using an Arduino in the long term and trying to figure out the right way to do it.

  When I have on average with the Arduino IDE I usually code that looks like this:

  float analogsum = 0;

  for (int i = 0; i)< 10;="">

  analogSum += analogRead (analogPin); where analogRead converts the analog value to a value\ digital 10-bit

  }

  average = analogSum/10;

  I am trying to create this same feature in LabView. The only way I can imagine the analog value of each iteration, in summary would be to store each value in a table, then add them together and divide by the number of iterations in my loop for.

  How would I do this in Labview?

• Table footer question

  
  I work on the automation of the tables through a publication and I wonder if there is way to create a footer line that appears only on the last page that extends on a table. Any help with this would be awesome! Thank you!

  This isn't one of the options in the dialog box options Table of headers and footers. You can have it appear in the column of text, each Frame, or every Page. I would say simply by putting the footer information into the last row of the table and setting is not like a real page.

• To loop through the table (newbie question)

  Hello

  I've read and read but can´t seem to do what I want to do.

  I do a lot of forms in Livecycle, but can´t seem to understand even the easiest loop.

  Let's say I have a table with two columns and ten rows. TextFields in column A is called Cell1 and Cell2 B column.

  I want to look through all the lines for that:

  If (Cell1.rawValue! == null)

  Cell2.fontcolor = "255,0,0";

  on the other

  Cell2.fontcolor = "0,0,0";

  If anyone can help me with this, I would be very happy. Mayvbe I can begin to understand this, because it seems that I m missing certain functions very practices.

• table join question

  I have two tables joined via a pk/fk relationship. The main table has a field that indicates if a person entered the House (that's a request for home detention for minors) and to the left, or if it is still in the House.
  
  1 = entered and left, 0 = always in the House.
  
  The two tables are related through three fields (ID of the person, House ID, date of entry in the House)
  
  I need a query to retrieve the records that exist in table 1 (the master) but do not exist in table 2 (retail) for (young) people who are STILL in the House. I need the query to run on the House n ° 2.
  
  I tried a number of relationships to join, but none has been successful.
  
  Any ideas on how to write this request will be appreciated.

• temporary table unanswered question

  Temporary tablespace issue
  I worked on tablespace temp for the last 4 days some of the question which are not clear about the temporary space
  (1) why is it that for optimal performance, the UNIFORM SIZE must be a multiple of the parameter SORT_AREA_SIZE if SORT_AREA_SIZE 4 m and ONE SIZE 32 m what impact on the reason for the performance
  (2) can be used in10g retractable or 11 g for the temp tablespace command
  (3) MAXSIZE UNLIMITED when I put this time deposited 32 GB it triggered error. Unlimited average as long as physical space is available it must measure but that's not why this limitation. It is the only one associated with the file temp or same problem occur if the data file size 32 GB?
  (4) if I know that my application to do a lot to sort out what is the best way to set up the temporary tablespace so that I don't up space error finished
  (5) ORA-01652: unable to extend temp by 4096 segment in tablespace TEMP this error occurs when I load the data using my application
  Please help in this regard, I am very grateful to you

  Adeel,
  I know VERY less, probably less when it comes to this forum. I know that just O of Oracle.I can not tell how long you take to learn Oracle as it depends on many things, how you study, focus, practice and above all, how much less you think you know. Because I meet a lot of people who think they know too that leaves no space for an extra addition of knowledge :-). I know really very low.

  If I use the LARGE folder to create a temporary space that doesn't solved my problem because I just read in the documentation if your block size is 8 k and OS 32-bit Platte basic form, you can size of 32 TB file. Using this approach I can fix this error condition
  Yes, bigfile can ovecome your space issue. But that could be cure a symptom. The real problem, is that why you do so much sorting that is not able to accommodate itself in memory and is traded on the disk. You should check with your queries and see if you can avoid some unnecessary sorts or things PGA.

• Join table newbie question

  Hi all
  
  I am pretty new to SQL and need assistance from base on accession to these queries.
  
  I have a query:
  
  Select lower (user_name) with users;
  
  and another:
  
  Select lower (us.username), max (TIMESTAMP)
  of sys.dba_audit_session us

  Query 1 returns now a lot more results than query 2, but I would like to join the username column of the query 1 and 2, while showing the timestamp for users where it exists.
  
  Any help appreciated

  something like this (statements are just to simulate your data)

  WITH u AS (SELECT 'Bob' username FROM DUAL
             UNION ALL
             SELECT 'Fred' FROM DUAL

• Impossible to get Graph.DataSource to work in WPF, I (thread question?)

  My chart is work beautifly when I use:

  chartCollection.Append (measure. GHz, measurement.dB);

  But when I try to use this call to the same method, I get nothing on the graph:

  Double data = new double [256];
  
  ....
  
  Graph DataSource = data;

  I know not if there is a suspicion, but I declare chartCollection on the main thread, and then pass it on to a different thread to collect data and it draw in real time.

  I could have lived with chartCollection.Append but in this case, I got a lot of data instanteneusly and I want to assign to chart at a time.

  Moreover, it seems that you need about 350 ms differ between each card. Add to not cause exception... but in my case I need to delay in all cases (for data) is not a problem.

  Thank you!

  I'm not very clear on how you mix the table/matrix updates. Here is an example of chart queue adds via the dispatcher (using a class task and assistance as a quick way to simulate the substantive work). You can use any delegate with the dispatcher, so you can assign DataSource in a delegate instead of use the method append on a collection of table.

  public partial class MainWindow : Window {
        private readonly ChartCollection chart = new ChartCollection( );

  public MainWindow( ) {
            InitializeComponent( );

  this.graph.DataSource = chart;

  var worker = new Worker( this.Dispatcher, chart.Append );
            Task.Factory.StartNew( worker.DoWork );
        }

  private class Worker {
            private readonly Dispatcher dispatcher;
            private readonly Action append;

  public Worker( Dispatcher dispatcher, Action append ) {
                this.dispatcher = dispatcher;
                this.append = append;
            }

  public void DoWork( ) {
                for( int i = 0; i <= 360;="" ++i="" )="">
                    double value = Math.Sin( i * Math.PI / 180 );
                    this.dispatcher.BeginInvoke( this.append, i, value );
                    Thread.Sleep( 100 );
                }
            }
        }

• Table optimizatioin of construction

  I suspect that my table/matrix construction begins to inhibit data collection. I'm currently collecting spatial data of the image. To collect spatial data of the pannel (gui) before I am establishing data of bad coordinate of a XY Chart with a background image. The sub vi reportoire start tent to prepare the Cartesian coordinates to set motion in the scene.

  How can I accumulate more effectively X, Y/horizontal, vertical/coordinate/pixel location etc. information of a given image. In this vi I try to do it by building a table with data from bad. The Zth deminsion can be moved.

  Thank you very much

  I changed to aray of writing in a file which I think works well. A bit of trouble with my table zth but resolved question.

• Reverse and pseudo inverse Matrix on FPGA

  Hi all

  How can I calculate matrix inverse/pinv on pushed more logical clock (*.gcdl), for FPGA? (Labview Comms 2.0)
  Maybe someone has a solution for this task? Or that the best algorithm I use for this task?

  Thank you.

  Hello togoto,.

  We have matrix Inverse and matrix screw Pseudo-inverse for code side host, but these are not supported on FPGA. The reason for this is because without a known matrix size, there is not a way to implement a dynamic matrix math function (the compiler couldn't know how many resources which requires). If we consider that more algorithms of inverse depend on the division, which is very intensive on FPGA resources, which provides another reason why we would be unable to put implementation in CDL.

  That being said, Comms has Matrix multiply and transpose the matrix of features that you can implement in CDL. Because for a long time the matrices are always a fixed size and uniform, you can implement a custom algorithm to achieve pseudoinversion and matrix inversion. It would take careful pipelining to ensure it worked in a single clock cycle.

  Could you elaborate on what exactly the application is supposed to accomplish? If possible, the math movement matrix your screw host-side may be the best approach.

  Best,

  Daniel
