• BlackBerry Smartphones Blackbery protect not function Curve 9300

  Hai guys,

  I try to open my Application of protection on my BB Curve 9300 Blackberry. But hang and displays the message error starting: Dryad bb rim net gui: symbol 'Device security under attack' not found.

  Please help to resolve the error and makes the BB Protect function.

  Thanks and greetings

  Your problem can be corrected!

  1. try to reinstall Blackberry protect

  2. try Factory Reset and check if its working.

  3. try Netqin app that also has contacts and location remote services.

  4. If you still want to desperately Blackberry Protect try to recharge your device OS.

• Color curves adjustment.

  Hi, I use PSE 9 and I find very good for the price.  I am now retired, but when work used Photoshop 6 to work. I found much easier rather than levels curves color adjustment and had a better mastery of the desired result.

  This option is not available on PSE 9 I wondered if it had been included with PES 10.  If not, can anyone suggest another option to adjust the color of the curves more than to have to pay for Photoshop CS5?

  Regards dpi300.

  Nothings changed in this regard in ESP 10.

  There is sort of a function curves under Enhance > adjust color > adjust color curves.

  If your Windows, Smart curve looks like real curves except that it is not an adjustment layer.

  Not sure if there is a free plugin for mac that does the same thing with the exception of action of curves in grant tools, but you can only set the RGB channel.

• CursorX alignment with a superficial given value

  Thanks in advance for any help:

  I use DIAdem 2011 and am looking for the Script function that will give me a value (time cursorX) when I locate a measured surface location. The problem I have is I can place the superficial on a situation of tension on a curve, but the cursorX does not follow (almost as if it were in "Free cursor" mode).

  I'm looking to measure delta time from two places different from voltage on a signal using the cursorX and cursory.

  I use the 'Frame', function "Curve slider" slider.

  Any ideas?

  Thank you

  Hi, SJD,.

  I think it is a mistake to send only a single value to a channel.  If you want to view this set of 4 scalars, I recommend sending to the legend of the VIEW or DISPLAY text or a floating dialog box.  I enclose the text box option SEE below.  The 'slope Info Start.VBS view' could be added on your existing script - it sets up the 'View slope Info Event.VBS' script to execute every time the cursor changes.  Then the layout 'View slope Info.TDV' shows the information in the upper text display area.  I had to press to the text box to refresh the strength, but I didn't think it was usually necessary.  You will need to modify the TDV I sent to show your Television '"command entry' ' or some XY trace you want to measure the slope of.

  Ask if you have any additional questions,

• Piecewise linear function fitting

  I have data which approximates the following function:

  f (x) = A; x<>

  f (x) = Bx + C; E<><>

  f (x) = D; x > F

  I am using the non-linear adjustment function and problems with a singular matrix error. According to me, I approached my settings quite well and the best track of the fitted curve seems fairly well aligned, but it seems that's not iterate through my approximations E and F and just using what I give him. Could someone take a look at my code and give me some additional tips? The points that I particularly need are the value 'A' and when f (x) = 0 of the second function. If there is an easier way to find these values, I'm all ears.

  Thank you

  Yes, you have only four parameters.

  1. Beginning level
  
  
  2. End level
  
  
  3. first x
  
  
  4. second x

  (interpolating linearly between the first and second x from the first to the second level).

• function with a variable number of cubic curves

  Hello

  I have a set of data : a set representing the independent variable and a set representing the dependent variable. I need to find the minimum number of cubic curves (find their coefficients) that reduce the average quadratic error less than a given tolerance. If the tolerance is higher than 17 particular segments, so I need to raise an error.

  You have an idea what function blocks, I need to?

  I could use general polynomial Fit VI with order 3 and its default method to check the residue. If the residue is greater than the given tolerance, so I could try to use two cubic curves and test them on different starting and ending points until the residue is less than the given tolerance. If tolerance is not guaranteed, I add another curve and I test again the Assembly as shown above. By iteration until the residue is less than the given tolerance, or until I would need to add 18th cubic curve.

  If there was something ready, I would be grateful.

  Thank you.

  Please, you can test your VI adding another point to four present?

  X =-6453

  Y =-266

  Check the residue.

  Thank you.

  Did you even read my response? You have a serious air conditioning problem because the data is on a narrow Beach far from zero. By example-6500 ^ 3 is smaller that - 2E11, i.e. a value that many (many!) is orders of magnitude different from that of the constant term (1). The linear algebra problem that results is very ill, conditioned and just blindly Ford over the accelerator pedal are bad advice here.

  This isn't a problem with the implementation of LabVIEW, but a fundamental vice that you encouter also (or worse) If you would do your own math. No way around it. (See also)

  My recommendation is to delete the X offset and add it later again. Now things work correctly. (Note that a second order polynomial fitting still works without twist it).

  Try the and see for yourself.

• curve adjustment function does not work

  Hi all

  I am trying to bend fitting, a graphic. but the curve adjustment function does not work. I get no output curve.

  which suggests to me u.

  Thank you

  You have been asked to view the code. We cannot solve the photos.

  Matrices X and Y are same length? Is a NaN value? What the output error say you?

  (Also note that in this case, it would be convenient if we don't need to wire x take a look at this idea!)

  This discussion is useless until you attach a real VI and data, so please.

• I'll make a small program that draw a curve function 2D using openGL, doable?

  1, I have a lot of sample data, it can be map plot a 2D of the distribution of the dot.

  

  2, then I need to climb a curve function, such as:

  

  CVI can use OpenGL functions: there is a specific OpenGL instrument located in \toolslib\custctrl\cviogl.fp. There is also an example of program that actually use the OGL functions to draw 3D sufraces: see the code in \apps\oglscxi fodler.

  That said, because you're dealing with 2D plots, do you really need OpenGL? All the steps you mentioned above could be addressed with the standard of CVI functions: for example, you can use a PlotXY () call properly formatted to draw the curves as in step #1, PolyFit () for calculating the interpolating to step #2 (which also goves the formula you as in step #5) and cursors to draw research as in the #4 step.

• Can curve hold functions defined Isoquant handful of VI?

  I'm trying the curve Fit VI non linear (Constrained) to analyze a step response.  Is it possible to define a parameter to adapt to a change in the weather?  In this way, I won't so ensure to get the precise start of the analysis window.  For example y = f (x (t - t0), a = [a0, at1]) or y = f (x (t), a = [a0, a1, t0])?  It requires an IF (case report) inside the function.  You can do this in Excel, so I thought that LabVIEW could do it too.  See attached simplified example of a linear adjustment deferred in time.  It gives the error-20041 occurred at NI_Gmath.lvlib:Nonlinear Curve Fit LM.vi:1. Possible reasons: analysis: the system of equations can be solved because the input matrix is singular.

  Kind regards

  Try this instead. Seems to work very well.

• Curve adjustment not linear function

  Hello everyone:

  I'm a little new here and at the same time a new learner for labview. My need for laboratory to adjust the data which are not linear, so, I choose to use the model non-linear curve VI. But when I run the VI, the error is that:NI_Gmath.lvlib:LM formula function.vi:7290001 string, or other displayments of the error. I tried several times, but unfortunately didn't. The problem may be the expression of the function form. Moreover, the design of the VI is not mine, it's Forum OR. Any constructive suggestions will be welcome.

  The form:

  y = Y0 + (Nr * cos (A)) + *(x-W1)/((x-W1) a1 ^ 2 + L1 ^ 2) + a2 *(x-W2)/((x-W2) ^ 2 + L2 ^ 2)

  In fact, the form is very long, I just write some.

  
  

• Introduction to the tutorial of curve fitting - find a function

  I'm new to programming in Labview (and programming in general) and so I'm learning the different functions in Labview that are likely to be relevant to the work that I do.  One of the functions I'll take advantage in Labview is the curve of the functions.  To this end, I found a number of tutorials that are available in the area of the developer, and the plan is to work my way through some tutorials apply in order to understand the processes involved (and how to use features etc.).

  The tutorial that I am currently working my way through is the Introduction to the tutorial Curve Fitting, and is where I am currently blocked.  To work through the linear curve of squares vi, as shown in Figure 3 of the tutorial, I can't seem to find the function that the linear data vi and the vi curve are interconnected and which connects to the curve of the linear model.  When I say that I can't find the function I want to say that I can't find the feature with the Schwaar icon in the Labview version that I use currently (it is the Labview 8.6 development system).  Can I get help with the function I need to use?

  I note, however, that the tutorial was written in 2006.  Would be - why I'm unable to find the function indicated (that is to say, he has changed since this tutorial was written)? If this is the reason why, anyone knows what is now the correct function?

  The tutorial can be found here: http://zone.ni.com/devzone/cda/tut/p/id/7669.

  Thanks for your help.

  Hey Scottum,

  This is the function table to build in the range of table in respect of the programming.

  If you hover over it in top and bottom of the function, you should see two small squares.  Mouse over the squares and your mouse turns into a vertical head double arrow.  You can drag the mouse in the vertical direction to expand the service to include more inputs.

  Hope this helps,

• How can I reverse the function of the curves in the dialog box change the curves

  in the oldest version of PS, there was a small set of arrows to reverse the function of the curves in the change the curves dialog box. I miss it greatly, because I use them in front of the standard direction for more than 20 years.

• Function of camera Raw default your curve / contact information

  Hello

  I would like to know where I can find the function / coordinates for the Lightroom / ACR default curve of tone that applies to any image.

  I think it's the red in this image, or it is very very close:

  

  I want to generate a lookup table to match its effect. For the moment I plotted something that is very very close, but I lack the precision to the bottom of my curve.

  See you soon,.

  Thomas

  Search for dng_tone_curve_acr3_default in the SDK.

  Most of the new profiles are don't have the default curve; Indeed, they combine research with the curve tables. Older profiles - back to LR 1 would probably be a better place to watch.

• BlackBerry Smartphones old Curve 8310, point Orange &amp; some functions limited-Solutions?

  It of a former silver/gray Curve 8310 works very well except no text. Did a hard reboot, wiped phone, downloaded news and updates of the site Web of BB. ATT network. There is some restriction on the phone that keeps me change features, formats code or firewall. To what I want to change (like the formatting of the text), there is an orange dot, an indication that this issue is not editable. Maybe it's old corporate phone with restrictions. A judge strange hard reboot does not eliminate the restrictions. All solutions? TKS

  Hello and welcome to the community!

  If there is a latent policy, there is only one way to remove it... and while I can't tell exactly what you hear of "hard reboot", this probably isn't the appropriate method. To check, however, see this:

  • KB30076 How to check for an it on a BlackBerry smartphone policy

  And, even if it seems to result in a negative, there is perhaps a COMPUTER policy on board... 'stealth' rare, but they exist. To clean, you must do:

  • KB31291 How to reset a BlackBerry smartphone to factory using BlackBerry Desktop Software Settings

  Of course, remember to take a backup before and after restore... but do not make big. One of the saved databases contains policy COMPUTER and, if you restore that, you'll be right where you started. On the contrary, only backup/restore these specific databases that need you, specifically avoiding those that relate to politics. You can find a complete set of instructions in the thread linked to my auto-sig on this post.

  Good luck!
