Function Super Gaussian

Hello, everyone,

I have the super Gaussian beam profile, it is attached. I would like to hold a kind of function on it.

Maybe someone knows a super Gaussian function?

See you soon,.

625 x noise specification

I have a card PCI-6255 that I intend to use for certain sensitive measures.

I'm trying to put together a budget-to-end error and I have a few questions.

My model is in terms of number of analog-to-digital converter (also known as the LSB in your datasheet).

In the table of absolute precision on page 5 of the 615 x standard OR I see a column called random noise, (uVrms).

I think I understand the residual gain error, offset error residual and associated with it and the INL error, but random noise is confusing to me.

Here's why: on the +/-2V of type range, the random noise is 16 uV. On this beach, the resolution of the ADC is 6.1 uV so random noise is about 2.6LSB

If I look at the +/-5V Beach, I see a random noise of 140uV. On this beach, the resolution of the ADC is 305uV so random noise is well under a LSB.

Therefore, in the budget of my mistake, I can use "1 LSB" for noise random when on the beach of 5V, but I have to use LSB '2.6' or '3' when the type 2V range.

I expect a signal of about 150 mV riding on a 2, 5V CC. I was worried, I might need to compensate the signal (remove the 2, 5V dc) in order to use the +/-gamme.2 volts to get the best resolution. Also, I thought that I would get better sound performance too. In looking at the figures here, but looks like I'd be better off using the +/-5V range (assuming that there is enough resolution) because the readings have less noise counties (even if it's more noise volts).

I can explain the error of Gain and Offset error by injecting known signals and making a "correction of the software. Not sure, but I think I can correct for the INL also if I use a 2nd or 3rd order polynomial. It is the random noise, I have problems understanding.

Here's the question: what is the random noise in table AI accuracy for 625 x boards? Can you give an example of how NEITHER could have measured it?

Secondly, note 2 says "sensitivity is the smallest voltage change this canbe found. It is a function of the noise. "He measured with a signal to noise ratio of '1' or '2' or some other standard, or is it a calculated value?

Thank you

The function of Gaussian Distribution is often used to describe the noise. Random noise spec'd in the table of precision is a gap type distribution of probability of noise and was probably calculated using statistical analysis. That's why the uncertainty of noise takes into account a 3 coverage factor that represents the largest part of the distribution.

With respect, the specification of sensitivity, this requires a more detailed explanation, but it is essentially an industrial standard that takes into account more statistical analysis on a signal when awarded with noise. According to me, the mix is a compoenent of this measure.

Control number of the howto of calls to a PLSQL inside a VORowImpl

Hello experts!
I am facing a problem of performance that I coded a calling a PLSQL procedure to calculate the value of an attribute to the get VORowImpl method.
I noticed that the method is executed several times for each record. That I currently have 13 records and 56 calls are connected to the PLSQL (4 calls per type of registration, and in both cases, 6 calls!)
Is it possible to control the PLSQL procedure is called only once for each record in the table?
BTW, I use 11.1.1.5
Best regards
Jose.

For example, createRowFromResultSet()?

Create the ViewObjectImpl class, createRowFromResultSet() substitution, inside this method invoke functionality (super.createRowFromResultSet ()) by default and save the line created in a variable, call your plsql function, complete attribute and return created and initialized row.

AS3 base how to pass a method correctly?

Hello.
I'll build a play on words. I did a class array that will contain all the functions for the letters that appear in the game of words. (This class is related to my class file main .as).
I did a constructor function with a list of all the things I want to do (to define their own functions sup). For now I just placed trace ("this function") in the method until I write the real method then. The first statement works and I get the trace in the output area. But for the rest, I get this error message:
1180: call to a method may not set initCheckIfLetterIsCorrect.//or init whatever education is for all 5 of them.
What I am doing wrong?
Thank you

Background repeated with LinearGradient?

Is it possible to make a fill repeat when you use a LinearGradient? I would like to force the following background to repeat itself:
< s:Rect left = "0" right = "0" top = low "0" = "0" >
< s:fill >
< s:LinearGradient rotation = spreadMethod "90" = "repeat" >
< s:GradientEntry color = "#717681" / >

< s:stroke >
< s:SolidColorStroke color = "#565 c 65" weight = "1" / >
< / s:stroke >
< / s:Rect >
spreadMethod = "repetition" does not appear to have any effect.

-Very well, so I'll assume you want to dynamically create Rectangles to completely fill a resizable space. What is your intention?

If Yes, then the most efficient method is draw programmatically. I create a component from MXML to the Group and replace the updateDisplayList function. In this function, you'll want to draw your rectangles according to the space available.

Thanks a lot for reading long code.

Hi Kiran, this is your class in place of the stuff as mentioned in the classes below that it's

or if you can change it yourself here I use the custom component and I import this component custom demand... so use custom component to send event cairngorm...

the best practice is to create a display component, and then import this view in your application and which will reduce the file size of your application and file size of download... so if you have any problem using this code let me know

Give me counsel how to listen itemRender parent mxml file event where the final TileList?

I guess the problem lies in what parateters you pass to your constructor DeleteFavoriteEvent. In fact, it is a parameter, you do not pass: bubbles. It is default to false, which means that your event not be the propagation phase. This is why he does not move to the top of the display list and TileList of your parents does not. So just pass 'true' as second parameter to the constructor of the event and see if that helps:

private function handleDeleteClick (event: MouseEvent): void
{
dispatchEvent (new DeleteFavoriteEvent (myData.carNumber, true));
}

Now I don't know if it's appropriate way to atchieve your goal (whatever it is). In my opinion, the stuffing out of your custom to the display list events is not applausable. But that's just my opinion after all.

Custom button class WordWrap

Someone knows how to make text wrap to a custom button class? I tried everything (as you can see below)!

You need to replace [] Measure to get the correct behavior. By default, the button sets the width of the TextField child. What you want is for the width of the TextField to be limited by the width of the button and the button height to vary the height measured from the TextField object.

I had a quick go at below, but it will probably need more work. I used the example of radio button Alex Harui multiline as a starting point:

http://blogs.Adobe.com/aharui/2007/04/multiline_buttons.html

SerializableAttribute public class WordWrapButton extends button
{
Protected Overrides function createChildren() (): void
{
If (! textField)
{
textField = IUITextField (createInFontContext (UITextFieldNoTruncation));
textField.styleName = this;
addChild (DisplayObject (textField));
}

super.createChildren ();

textField.multiline = true;
textField.wordWrap = true;
}

Override protected function [] Measure: void
{
If (isNaN (explicitWidth) is false)
{
textField.text = label;

textField.width =
explicitWidth-
Value ("paddingLeft")-
Value ("paddingRight");

measuredHeight =
textField.getExplicitOrMeasuredHeight () +.
Value ("paddingTop") +.
Value ("paddingBottom");
}
on the other
{
Super.Measure ();
}
}

override protected function updateDisplayList)
unscaledWidth: unscaledHeight, number: number): void
{
super.updateDisplayList (unscaledWidth, unscaledHeight);

() textField.setActualSize
textField.width,
textField.getExplicitOrMeasuredHeight ());

textField.move (textField.x, value ("paddingTop"));
}
}
}

Pass data from one XML object to an itemRenderer

I'm trying to color the background of a column in a datagrid, and we found a sample file that illustrate the concept. However, the sample has data stored in an arrayCollection collection, while mine is in an XML object. The problem is that the data from the sample file apparently automatically passed to the itemRenderer (below: notice the trace statement). My XML object does not automatically pass to the itemRenderer data. So my questions are:
1. is there a simple way to pass data stored in an XML object to an itemRenderer
or
2 should I convert my XML an arrayCollection collection? If Yes, what is the best way to do it - I tried the following, but without success:
< mx: Model id = source = "example3.xml" / "xmldata" >
< mx:ArrayCollection id = "myAC" source = "{ArrayUtil.toArray (xmldata. Example1)}"/ >
Here is what the XML looks like:
< TABLE >
example < 1 >
< Difficulty > 0,5 < / difficulty >
< discrimination > 0.7 < / discrimination >
< item 3 > < / point >
< / example1 >
< /table >
Here is the itemRenderer:
<? XML version = "1.0" encoding = "utf-8"? >
" < = xmlns:mx mx:Label ' http://www.Adobe.com/2006/MXML ">

This code example should answer your question of how to import data in the renderer automatically. It is through the dataProvider of the DataGrid and then refer to it in the renderer in the form of data. XYZ, where XYZ is the field in the XML file with the data. See FB 3 help sys on the e4x syntax.

Where to start with "composite component?

Hello world. I'm having a hard time to understand how to create a composite base component. There is an online help on this, but for some reason, I just can't follow it. Honestly, I'm not trying to find someone here to do my job for me, but I hope that if a very simplified version of what I need to do, has described that someone could show me how do through code.
Here's what I'm looking mainly to (generate a control that is a combobox with a button on the side of it):
< hbox >
< combobox / >
< button / >
< / hbox >
Do something like above is pretty easy. But what I really need, is for the control of the root must be a combobox so that all of the properties and events for the combobox control are available to its owner without having to re-do/proxy of them myself.
I hope that this will illustrate the concept:
< combobox >
< button / >
< / combobox >
I see the doc I need an ACE of the class and must override updateDisplayList, createChildren(), etc.. But for some reason I can't understand the doc to do something even this simple enough. I think that if someone showed me how to make this example, it would be a good starting point for me to go back to the doc and I hope it'll make more sense!
Thanks in advance!

I think the op is loking for an example of composition that begins with the extension of some components like ComboBox and then adds another control. the advantage of this is that the new control can be treated as a ComboBox with all its features. Here is an example. You have to find your own image to use for the button, or replace it with a normal button.

Test application:

layout = "absolute".

Grid newbie - DataGridColumn styles
I am very new to Flex so forgive me if I'm missing something very basic. I looked in all the documentation on how I could have either different color or thickness of horizontal grid lines throughout my DataGrid. I'm currently building a book of calendar time and I want to increments of 15 minutes (lines) pertaining to the time (1st 4 rows) they are below and then have a dark line prior to the next hour. Is it possible to accomplsih this? Thakns in advance!
Thanks, that did the trick. I have not seen a way to make the casting in the documentation (at least by reading what I had to this day) and ActionScript is quite different from all other languages script/program with which I worked so I couldn't guess how. I really appreciate your help on this!

Answer:

Col: DataGridColumn var = new DataGridColumn (columnName);
col.itemRenderer = new ClassFactory (AppointmentBookCellRenderer);

Custom creation for AreaChart AreaRenderer problem
First question: if I buy the graphics package, can I get the source code? That would certainly solve my problems.

OK the real question: does anyone have a quick example class that is a custom for an AreaChart AreaRenderer?

I am trying to create a custom of the AreaRenderer implementation. According to the docs, I need to implement the interface "AreaRenderer' (no IAreaRenderer (?)) who supposedly resides in the mx.charts.renderers.interfaces but Flex Builder complains that the interface is not found.

Link to documentation: http://livedocs.macromedia.com/flex/15/asdocs_en/mx/charts/renderers/interfaces/AreaRender er.html

Otherwise, I tried simply stretching from AreaRenderer but methods: draw, beginDraw and endDraw seem not to be there, or are not substitutable?
Ugh I always to understand these things right after that I have post. I was hitting my head on this for more than a day too.

In any case, for someone else, everything you do is extend ProgrammaticSkin and implement IDataRenderer. Here is my example class:

package
{
Import mx.core.IDataRenderer;
Import mx.skins.ProgrammaticSkin;
Import mx.charts.series.items.AreaSeriesItem;
Import mx.charts.series.renderData.AreaSeriesRenderData;
import flash.display.Graphics;

SerializableAttribute public class MyAreaRenderer extends ProgrammaticSkin implements IDataRenderer
{
private var _data:AreaSeriesRenderData;

public function get data (): object
{
return _data;
}

public function set data(d:Object):void
{
_data = d as AreaSeriesRenderData;
}

override the updateDisplayList(width:Number,_height:Number):void function
{
super.updateDisplayList (width, height);

var Graphics = g:Graphics;

g.Clear ();
g.moveTo (width, height);
g.beginFill (0xFF0000);

(hint: string var in _data.filteredCache)
{
var point: AreaSeriesItem = _data.filteredCache [index];

g.lineTo (item.x, item.y);
}
g.endFill ();
}
}
}

Still, I would like to know if get you the code source for charting package, however.

Custom component Help
Hello

I'm trying to pass a variable to a custom component that I did. Here is my list of import for the script AS:

Import mx.controls.Image;
Import mx.controls.Label;
Import mx.containers.HBox;
Import mx.containers.VBox;
Import mx.containers.Panel;
Import mx.containers.Canvas;
Import mx.events.FlexEvent;
import flash.events.Event;

The script essentially make a picture of a thermometer and then I pass a value and it increases the level of 'mercury '. Here's my .mxml script that works fine:

< mx:Canvas label = "Test" width = "140" height = "268" y = "10" >

< custom id: thermometer = "thermo" y = "10" x = "10" Temperature = "27".
high value = relax "50" = "0" title = "Office" width = "116" height = "245" / >

< / mx:Canvas >

That is why a photo of the thermometer exactly as it should. My problem is that when I moved the component a varaible like {pSrv.lastResult.data.current.RH_OFFICE_CURR} it doesn't work anymore! I have no idea why, and I hope that someone has had this problem before. Why can't I send these data to my component?

Here is the solution discussed:

package components
{
Import mx.containers.Canvas;
Import mx.containers.VBox;
Import mx.controls.Image;

Thermometer/public class extends Canvas
{
/ * Variables for the child components * /.
protected var canvas: VBox;
protected var top_img:Image;
protected var bottom_img:Image;

/ * Flex calls the createChildren() method when
* the components are added. This is the right place
* implement control. Any final design, etc..,.
* occurs in updateDisplayList * /.
override protected function createChildren() (): void
{
super.createChildren ();
If (! canvas)
{
canvas = new VBox();
canvas.setStyle ("verticalGap", 0);
addChild (canvas);
}

Create and initialize the top image.
If (! top_img)
{
top_img = new Image();
canvas.addChild (top_img);
}

If (! bottom_img)
{
bottom_img = new Image();
canvas.addChild (bottom_img);
}
}

/ * Set the picture styles * /.
override protected function commitProperties (): void
{
super.commitProperties ();
top_img.source = ' img/blue.png;
bottom_img.source = ' img/red.png ';
}

/ * updateDisplayList positions, sizes and draw something it takes * /.
override the updateDisplayList(unscaledWidth:Number,_unscaledHeight:Number):void function
{
super.updateDisplayList (unscaledWidth, unscaledHeight);

TODO: use the unscaledHeight property to determine the
good scaling for the control.
top_img. ScaleY = 20;
bottom_img. ScaleY = _temp;
}

override protected function measure (): void
{
Super.Measure ();
measuredWidth is measuredMinWidth = 75;.
measuredHeight is MaxHeight = 200;.
}

public void Thermometer()
{
Super();
}

[Inspectable (defaultValue = 1)]
private var _temp:uint = 1;

[Bindable (event = "tempChange")]
public function get time (): uint
{
Return _temp;
}

public function set time (value: uint): void
{
_temp = value;
invalidateDisplayList();
}
}
}

button in the datagrid not pulling cell click event
I have a datagrid with a custom button built in Actionscript rendering engine. I'm trying to figure out how to capture the click event of the component when the button is clicked.

I am generating the component of the cell based on the field type:
column.itemRenderer = new ClassFactory (DpFileRenderer);

The element itself:

package joe.ui {}
Import mx.controls.Button;
import flash.events.MouseEvent;
import flash.events.Event;

SerializableAttribute public class DpFileRenderer extends button
{
[Embed("/assets/icons/drive_disk.png")]
private var diskIcon: Class;
[Embed("/assets/icons/drive_disk_grey.png")]
private var diskIconDisabled: Class;

override the updateDisplayList(unscaledWidth:Number,_unscaledHeight:Number):void function
{
super.updateDisplayList (unscaledWidth, unscaledHeight);
This.label = this.listData.label;
If (this.listData.label! = '0')
{
this.setStyle ("icon", diskIcon);
} else {}
this.setStyle ("icon", diskIconDisabled);
This.Enabled = false;
}
this.labelPlacement = 'left ';
this.setStyle ("color", 0x000000);
}
}
}

I don't know exactly on where to put a diffuse in this event.

Could someone help?

Thank you.
Add an event listener in the constructor of your rendering engine and dispatches the event from the Manager. You certainly want the event to bubble as well.

Here's an example, using a text control, but the theory is the same.
