VI to calculate partial derivatives and curvature on a surface

I have a surface (a series of x, y, z triple that form a grid, measures, not a formula). I want to calculate the curvature at each point of the grid. I already have a smoothing and interpolation, so it doesn't have really sharp edges. I understand that I can not calculate curvature to the edge because I need adjacent squares. Is there a routine LV integrated for this or should I write my own?

If I have to write my own routine, I'll write a nested loop that goes along each row and column of the grid. At each point, I'll estimate the matrix of 2nd partial derivatives by finite differences. Since I have will calculate the maximum curavature, or a minimum radius of curvature, at this time there (once I found the formula, which I have not quite finished).

I appreciate all the suggestions; I hope that there is already a VI to do. Thank you.

Hi, WCR.

For the calculation of the curvature, we only have a VI IMAQ called "IMAQ classify Curvature.vi" (http://zone.ni.com/reference/en-XX/help/370281P-01/imaqvision/imaq_classify_curvature/) that will calculate the curvature for you. However, it is a function of the NOR-IMAQ driver, and it only accepts an image of contour. So if you don't plan to treat it with a photo, then you will have to calculate the minimum/maximum curvature with our artihmetic vi.

There is a VI that will compute the partial derivatives called "Derived partial of f (x 1, x 2) VI" (http://zone.ni.com/reference/en-XX/help/371361H-01/gmath/partial_derivatives_fx1x2/). It notably VI will calculate a 2D of two independent variables table.

I hope this helps!

How to calculate the second and minisecond for audio landmark
I'm doing a sound synchronization for the clip audio and video in Flash. I found a tutorial on the web, and it seems to work. However, I do not know how to calculate the second and the mini (deuxieme from mp3 file. The first frame has the following lines to set the duration for each animation:
Import class
Import net.quip.sound.SoundSync;

Stop the main timeline
Stop();

Create an instance of SoundSync
var ss:SoundSync = new SoundSync();

ss.addCuePoint ("IT", 20100);

I'm with you.

The code expects milliseconds, then 26 seconds would be written as
this:

26000

If he said 01:22 (one minute and 22 seconds), you must write it like this:

82000

... which is 60 seconds for now, 22 seconds
side, then multiplied by 1,000 to get milliseconds.

Send partial, immediate and life-cycle problem JSF
Hello
I have a form with a text entry field and a "submit" button. The attribute value of the input box (* private String name *)
is a property of support bean and it is bound to a property RichInputText *(private RichInputText nameField;) *.
in the same bean support. The Send button has an action listener that calls a method in my backing bean * (displayText (ActionEvent ae *))
). Button send the part delivery set to 'true' and immediate attribute set to 'true '. With the value 'true' my understanding is that life cycle jsf defines "apply request values" and then passes the validation, update of the model goes directly to invoke application phase. With this assumption, in call, setNameField (RichInputText name) will be called (apply request values) and I should be able to get the value using the method getLocalValue() on the RichInputText
class. But when I try to display in my managed bean, it is null.

How can I access the entry in my bean support value when both the partial shipment and immediate attruibtes are set to true on my "submit" button?

Here is my support bean class:
public class SampleBean {}
name of the RichInputText private field;

public SampleBean() {}
}

private String name;

public void setName (String name) {}
myIdName = name;
}

public String getName() {}
return the name.
}

{} public void setNameField (RichInputText name field)
this.nameField = field name;
}

public RichInputText getNameField() {}
return name field;
}

{} public void displayText (ActionEvent ae)
System.out.println (nameField.getLocalValue ());
System.out.println (Name);
}
}

Hello

Well oops on my side. Yes, it the field isn't immediate value getSubmitted would not return a null value, but would be getLocalValue. There is an alternative if you do not use the trigger by calling processDecode (context) and processValidations (context) on the occurrence of input text before calling getLocalValue.

Kind regards

Suggestions of the Google toolbar are partially obscured and how do I load this updated toolbar?

I saw this problem before on another computer. The Roboform toolbar partially blocks the Google toolbar search suggestions. I think the fix that worked once was to reorganize and force the Google toolbar to load last in Firefox in the about.config settings. How is it that I forgot?

This has happened

Thanks for the replies. I'll try to get out them, but I think also there is a difficulty which worked via about: config that forced the order in which loading toolbars.

Anyway, thanks and I'll try that tonight.

Partial goal and partial release takes so long

Hello.
Here's my situation:
I'm a jsff to sell products.
I designed it with several images representing products. Each image is surrounded by a command link.
Whenever I click on the image I need to combine the value and display the output in a text.
My problem is that the action is taking so long. So, if as a customer, I need to buy 3 x product, I need the clock in the image (CommandLink) three times.
I add a partial trigger component, alternative, I've added a partial objective to add the partial trigger by program, but in the two options takes a while.
Did I do something wrong?
Another option to make is there of that?
Thanks in advance.

You are absolutely sure that the partial call target taking so long?

Calculate intermediate values and calculated values

I use OPA for a week or two and now understand how to structure evaluations logics, hierarchies, etc.
Now, as the calculations become more complex, I was wondering if it is possible to calculate the variables to be used in further calculations.
A good example may be I want to calculate the age of the subject for use in several calculations later in the logic. I have an incoming parameter that provides the subject of birth date - can I somehow fill a variable like "age of the subject = the number of years between the date of the topic of birth and the date of the day? "I want to fill ' age of the subject ' with a number instead of evaluate what true or false - is it possible?
The second part of the question, it is that I want the web service to return "the age of the subject" as the parameter value.
Thank you!

In Oracle Policy Modeling, 'attributes', the 'entities' and the 'relationships' are the terms that you will be interested. Attributes can be Boolean, or can be a value of various types of data. Consult the help for your version and search attributes, entities and relationships. A base attribute such as 'age in years' value can be calculated from other attributes such as "the data of birth of the person." An attribute that is provided as input via an external system or via an interactive interview is also called a base level attribute, while a determined political base don attribute can be an intermediate attribute (both determined and used as a condition to determine another attribute), or call a top-level attribute (determine on the basis of politics) (, but not used as a condition). The aid also includes examples of policies that are used to calculate the values of attributes.

Partial update and dimension values
Hello

A question about partial and analytical, updates the documentation is not clear (perhaps because of my Dutch interpretation :-)).

We have a dimension called 'platform' that is autogen. 2 new platforms (Wii you) and XBox 720 will soon be available. These values will be displayed when we use partial updates?

Thank you

Need help to calculate the start and end time and place the result in a term like text box

I did a search on the forum for calculating start and end time and found the code depending on which I am using as a formcalc on the duration field.
==============================================================
Form1. Page1.duration::calculate - (FormCalc, client)

If (HasValue (StartTime) and HasValue (EndTime)) then
industrial var = Time2Num (StartTime.formattedValue, "h: mm A")
var = Time2Num out_ (EndTime.formattedValue, "h: mm A")
If (IN2 > = out_) then
xfa.host.messageBox ("start time cannot be greater than or equal to the end time.")
$.rawValue = null
on the other
var out_ - IN2 = diff
$.rawValue = diff/3600000
endif
on the other
$.rawValue = null
endif
=============================================================

Then, when I enter for example from 15:30, an hour of beginning and end of 04:00

The duration field will say 0.5

How can I get my form to say 30 minutes instead of placing a decimal?

Secondly, how can I use field models LC where the employee can just type 330 or 03:30 and it automatically based on the computer's clock on time to start 15:30?

Any help will be greatly appreciated. Thank you.

To view the results in a regular time format, you can use:

$.rawValue = Num2Time (diff/3600000, "HH: mm")

For a flexible time entry check this example.

calculate adding them and subtracting to the same cell?

I created a table that has fields of digital type in them. I'm trying to calculate it from two fields and generate the result in a cell. for example, the first cell of the column begins with count quantity, second cell of the column is of type number of quantity to remove from the beginning and cell of the third column to add to the beginning cell. the calculation must be filled in the fourth cell of the column. I am able to create calculation script adds fourth cell by adding just - Sum (begin1 + add1) - but can not understand subtract in the same field.

Form1.Page1.Subform1.table.row [0]. total::calculate - (FormCalc, client)

$.rawValue = a + b - c

Hi guys,.

It's a situation where I have to produce a few new lines with projections based on Q4 RETAIL_SALES_AMT
RETAIL_SALES_AMOUNT and fourth ' rs following WHOLESALE_AMT. As you can see from the sample data for a specific customer,
product I have populated only until 01/04/2006 retail_sales_amt but WHOLE_SALE amt for the same product and customer
are there up to 01/04/2007.

I have to produce a PROJECTED RETAIL_SALES_AMT and it must be inserted in a new line with an indicator to identify
a proposed line. Here, in this case I have to produce a new line of projection from 07/01/2006,10/01/2006 and 01/01/2007
the RETAIL_SALES_AMT. The method of calculation is provided for in:

retail_sales_amt scheduled for 07/01/2006=.345+ ((01/07/2006 whole_sales-01/04/2006 whole_sales) / (01/04/2006 whole_sale)))
* 01/04/2006 RETAIL_SALES_AMT and move forward to subsequent quarters.

Is it possible that I can use a query to produce these new lines by calculating the RETAIL_SALES_AMT on the fly, or any other
How to procedure.

Please help as it seems a little complicated.

Hello

As far as I can tell, that's what you asked for:
```
WITH     got_prev         AS
(
     SELECT     table_x.*
     ,     LAG (wholesale_amt) OVER ( PARTITION BY  customer
                                    ,                product
                            ORDER BY      quarter
                           )     AS prev_wholesale_amt
     FROM     table_x
--     WHERE     ...     -- Any filtering goes here
)
,     tree     AS
(
     SELECT     got_prev.*
     ,     SYS_CONNECT_BY_PATH ( CASE
                           WHEN  LEVEL = 1
                           THEN  retail_sales_amt
                           ELSE  ( .345
                                          + wholesale_amt
                                          - prev_wholesale_amt
                              ) / prev_wholesale_amt
                          END
                        , '*'
                        )                    AS path
     FROM     got_prev
     START WITH     retail_sales_amt     IS NOT NULL
     CONNECT BY     retail_sales_amt     IS NULL
          AND     quarter               = ADD_MONTHS (PRIOR quarter, 3)
          AND     customer          = PRIOR customer
          AND     product               = PRIOR product
)
SELECT       quarter
,       customer
,       product
,       COALESCE ( retail_sales_amt
             , eval_number ( LTRIM ( path
                                       , '*'
                           )       )
             )      AS retail_sales_amt
,       wholesale_amt
,       NVL2 ( retail_sales_amt
            , 'F'
            , 'T'
            )          AS projected_flag
FROM       tree
ORDER BY  customer
,            product
,       quarter
;
```
I posted earlier the eval_number function.

In this query, a group of consecutive quarters, where the first group a retail_sales_num and the rest of the members of the group are not, is treated as a hierarchy. The retail_sales_amt of all members (except the first) will be based on the previous, as well as the wholesale_amts past and present.
Say that a tree is 5 points of time (as in your examples of data). We can calculate the 2nd point in several ways: using analytical functions, for example. But we cannot use the same formula to calculate the 3rd point, because the calculation of section 2 must be completed before we can calculate the 3rd. It goes the same for the 4th and 5th.
This is CONNECT BY arrives. CONNECT BY is one thing in Oracle SQL that can be recursively; children may find themselves once their parents are found, in the same way we want to calculate the nth retail_sales_amt once the amount of the n-minus-1 has been calculated. To do this, we use SYS_CONNECT_BY_PATH, where the first element in the path is the retail_sales_amt given, and all others are the factor to multiply this number to get the next amount.
SYS_CONNECT_BY_PATH produces a string like ' * 324562 *. 4965935 *-. 0057739', which should be interpreted as a number. TO_NUMBER won't: TO_NUMBER cannot convert only a single numeric literal. Instead, we have a function defined by the user who put this string dynamically in the SELECT clause of a query, where it is interpreted as a numeric expression.
