Mathlookup table - LUT Power 1/X vous savez ce qu'il fait ?

Bonjour, 
J'aimerais comprendre comment le LUT Power 1/X (MathLookup - Power 1/X). quelle est la theorie pour la construction de la table de correspondance de ce type de LUT power 1/X. 
J'ai déjà posté celà dans le forum en anglais : http://forums.ni.com/t5/Machine-Vision/Lookup-Table-power-1-X-IMAQ-Vision/m-p/1487912 
où j'ai expliqué le problème.Je suis plus à l'aise quand meme en français. 
Est-ce que quelqu'un peut m'aider ? Je dois expliquer dans ma these ce que mon traitement fait et je suis coincée sur ça. Quel est la fonction de ce LUT POWER 1/X  ???
Merci d'avance
Gabriela

Bonsoir,
Apparement il semble normale que ce bloque n'applique pas simplement un calcul Racine de 3 ( ou autre ) sur la valeur
mais plutôt une correpondance a une dynamique attendue.
un début d'explication ici :

  • Can I update datas of Power Query after making relation tables in Power Pivot ?

    Can I update datas of Power Query after making relation tables in Power Pivot ?
    I want to update datas at day by day to viewing today's graph by Power View on Excel.
    Power Query use to transform web site to Power Pivot data model table.
    Power Pivot use to making relasing tables, and making measuers.
    Regards,

    Hi Yoshihiro,
    Can you share an example of the things you are doing in Power Pivot? There are some operations that prevent the query from being refreshed in Power Query; this is not ideal so we are currently working on fixing it.
    Thanks for your feedback.

  • To make a table data in ill and then save as PDF

    hei,
    if I want to make kind of table in ill with text data and then exprot/save as.. PDF file, ~2 pages.
    How large should I take the new ill document width x height ?
    And if I want to make 2 pages on PDF, is it possible ?
    And if Im makeing table data, then I shoud use some grid in ill ?
    Thanks!

    You should know better how large the document must be, since you know, how you want to print it and how much content you need to enter.
    You can create multi page documents in many versions of Illustrator. How to do it, depends on your version. The search term would be multipage.
    Illustrator doesn't have a table feature. So perhaps using InDesign for the job would be a good idea. You can just draw some lines in Illustrator or you can create tables without any lines. This depends on how you want your tables to look.

  • Creating and updating table in JSP Through ADD and SAVE button

    how do I create a table in JSP which has certain number of columns and rows. I have a button called "ADD", which when clicked should add the data I entered. How do I update and save the same?, if there are buttons called "SAVE" and "DELETE".

    Do u want to add it to the database or just in the JSP Cache???
    I think if you want to add to DB, take the subject offline.

  • Query on Custom schema table getting 'Do You want to save changes' message

    Hi all,
    I am getting the error message whenever I query from the custom table. Here is the description of the issue.
    1. I have a button on the first block. When the user clicks on this button , execute_query is called on another block. Then the user getting the message "do you want to save the changes" . Although there are no changes made on the form.
    2. The second block is based on a custom table defined on the custom schema.
    3. Created public synonym for this table and also gave the all the grants to apps schema on this table.
    4. This error was not coming before when the second block is based on Apps schema table.
    Any idea on how to fix this.
    Thanks

    I doubt the problem is related to a schema or public synonym. The message is appearing because the value for an item is being changed after your query executes.
    First check to make sure that the blocks that are not based on a table are set to No. See the Database Data Block Property.
    If that doesn't solve the problem, then run the debugger and watch to see what item is changing. You may be doing something in a trigger.

  • Urgent : update of table QALS  through transaction QA12 after save

    Hello Experts ,
      I need to update the table field SELHERST of standard table QALS through transaction QA12 after the save button is clicked  .
    I have implemented the exit QEVA0010 which is triggered after clicking the save button , and have put the update command there , followed by commit work statement .
    But it is not updating the table QALS .
    Thanks in advance ....

    When the SAVE button is pressed, SAP execute some checks and launch the update task, if you want that your changes are not overwritten by SAP you need to submit those for execution during update task.
    So you need to use instructions like
    - PERFORM ON COMMIT
    - CALL FUNCTION IN UPDATE TASK
    and execute the update in one of these. (Reference [Updates in the R/3 System (BC-CST-UP)|http://help.sap.com/printdocu/core/Print46c/en/data/pdf/BCCSTUP/BCCSTUP_PT.pdf])
    You may also try to force the update in the main program, declaring a pointer (field symbol) in the calling program data '(SAPMQEVA)QALS'  (But that's not very correct)

  • Power Manager does not save my custom settings

    I'm running Win7 Pro 64bit SP1 (Swedish) and Power Manager v6.36 on my W530.
    When I create a new power profile, I go through all the 5 steps, but afterward no new profile exist. I only see the default 5 ones from Lenovo PM.
    Same thing if I change the setting in any of the 5 profiles, the changes aren't saved.
    This is reproduceable every time.
    The only changes that DO get saved are the settings on the Global tab like if I choose to do nothing when the lid is closed.
    Is there any way to get the Power Manager to work as it should?
    PS: I really miss the possibility to swiftly change power profile via a left click on the green power gauge next to the systray. Nowdays a single click load and start up the entire Power Manager application. This is SO tiresome when I just want to do a quick change of the profile.
    PPS: I had the same problem in v6.32 and just installed 6.36, but still the problem persists.

    It sounds to me that the two power managers are conflicting with each other. Try to make your custom power settings inside of the Lenovo Power Manager. 
    You can do this by opening the Lenovo Power manager and selecting the power plan tab, directly under the tab is a button that says New. When you select this a new window should open to allow you customize your own power schemes. You will be able to customize the System settings such as: Maximum CPU speed, Display Brightness, Graphics Power plan, also desired Idle timers, events, alarms an other advanced settings. Once created you will see your new power plan listed under the default power plans.
    If this does not work, I would then suggest uninstalling the Lenovo Power Manager and utilize Microsoft Power Manager.
    Good luck! Let me know if you have any questions

  • Peak Power Scheduler does not save

    I have a T420 and Power Manager 6.55 installed.
    Because my notebook is almost always working on the dockstation, it keeps charging all the time.
    Not good.
    So I decided to use the Peak Power Scheduler to use the battery at least once per day. But everytime I try to schedule a Peak Power Scheduler (no matter the configured schedule settings), after I close the Power Manager window and open again the schedule disappears.
    This does not occur with other schedule options (like screen time, power management options, etc.).
    Any idea?

  • Updating a table, however I would like to save the old info in another tabl

    Dear all; I have a table called table_one,
    Which contains the following info
    carid            place
    Benz            New York
    BMW            LondonThis information is usually going to be updated in the near future, however, I would like a situation where before the information is updated, the old information will be saved in another table called table_two first. so for example, from table_one, lets say New York is being updated to Toronto, I would like

  • Unable to load the tables in the Power Pivot Window – An Item with the Same Key has already been added

    Hi there,
    I recently had the following situation, where I changed the source of my CSV file in Power Query.
    Once I had reloaded the file, it would then not load into Power Pivot. So I disabled the loading from Power Query into Power Pivot. I then enabled the loading to the Data Model. Which then successfully loaded the data into Power Pivot.
    But once I went into Power Pivot, had a look, then saved the Excel file. Once saved I closed the Excel file. I then opened the Excel file again and all the sheets that interact with the Power Pivot data work fine.
    But if I go and open Power Pivot I get the following error: Unable to load the tables in the Power Pivot Window – An Item with the Same Key has already been added.
    This is what I get from the Call Stack
       at System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue value, Boolean add)
       at Microsoft.AnalysisServices.Common.LinguisticModeling.SynonymModel.AddSynonymCollection(DataModelingColumn column, SynonymCollection synonyms)
       at Microsoft.AnalysisServices.Common.LinguisticModeling.LinguisticSchemaLoader.DeserializeSynonymModelFromSchema()
       at Microsoft.AnalysisServices.Common.SandboxEditor.LoadLinguisticDesignerState()
       at Microsoft.AnalysisServices.Common.SandboxEditor.set_Sandbox(DataModelingSandbox value)
       at Microsoft.AnalysisServices.XLHost.Modeler.ClientWindow.RefreshClientWindow(String tableName)
    I would assume that the issue is with the synonyms and for some reason, when I disabled the loading of my data into the Power Pivot Model, it did not remove the associations to the actual table and synonyms.
    If I renamed the table in Power Pivot it all works fine. So that was my work around. Fortunately I did have a copy of the Excel workbook before I made this change. So I could then go and add back in all the relevant data to my table.
    Has anyone had this before and know how to fix it?

    Hi there
    I can share the work book, if possible to send me an email address. As the workbook size is about 9Mb.

    Hi,
    It seems like a javascript error, probably from client side validation of faces components. Are you using a supported browser? Have a look here
    http://blogs.oracle.com/jheadstart/2007/12/supported_browsers_for_adf_fac.html
    This is probably not a JHeadstart specific problem, could you try to create the same page using ADF drag and drop and see if the problem persist. Also please post your question on the jdeveloper forum: JDeveloper and ADF
