Trying to fit a curve with restrictions

I am trying to fit my experimental data with my own function y=a*exp(-x/b)+(1-a)*exp(-x/c) and I want the "a" paremeter to be >0 when doing the fitting.
Is there anyway to do so?
Thanks!

Yes, but you have to do it all yourself from scratch.

Any VI's capable of interpolating or fitting a curve with polar coordinates

Hi,
I have split a set of 3D data representing a human torso into many 2D planes and what i want to do run an interpolation on all of the points that fall within each of the planes in order to interpolate the entire torso. The problem is that for each x coordinate there are two corresponding y values so what i would like to know is if there is a VI that can interpolate cylindrical coordinates or if anybody has any suggestions on how i can go about doing the interpolation of one of the planes of the torso
alex

Hi Alex,
Could you take this XY plane and find the X points that only correlate to a single Y value. Then split the array at this point to divide it into two semi-circles (I would assume that one torso plane would resemble a circle) with unique XY pairs that you could complete an interpolation on. Once this is complete than you can append this data back together to form your complete dataset for the plane. Does this seem viable?
Thanks,

Sync Curve with Desktop using Bluetooth

I am trying to sync my curve with my desktop using bluetooth. Is this possible?
my desktop and curve are successfully paired
In connection settings, "bluetooth settings" are grey'd out - so I cannot select enable bluetooth- does this have anything to do with the problem?

Lorentz fit of a curve with Lev-Mar

Hello everybody! I am trying to set of data to a Lorentz curve to calculate a Q value (resonance.) I found a program on a thread from this forum that appears to work with the sample data set from the thread. However, when I try to run the program using my data set with known fitted coefficients as the initial guesses, we get an error in the Lev-Mar sub-VI -- something like “the input matrix is singular”. There’s a screenshot of my data in in the attached zip folder, as well as the text file containing my data.
My data curves down (reaching a minimum) instead of up, as in the sample data set, but it seems like that should be accounted for by the different initial guesses. I am thinking that something else is going on; hopefully it is something simple that I am just missing. Any help y'all can provide would be greatly appreciated!
Thank you!

Hello Lynn,
Yes, there are quite a few potential peaks in that data set. The peak you identified was the one that we are trying to fit (The peak should be trimmed by the cursors.) We used origin to fit that same peak in order to get the initial guesses for the coefficients in the screenshot. When it runs, we get the error message: "Error -20041 occured at NI_Gmath.lvlib: Nonlinear Curve Fit LM.vi:2 Possible reason(s): Analysis: The system of equations cannot be solved because the input matrix is singular."
Thanks!

Strange situation when trying to sync Curve with Outlook, time to admit defeat now.

Hi.
I have given up as a bad job on my main PC now trying to sync our two Curves with Outlook, get the 'Desktop Manger has encountered a problem an needs to close' message each time and have tried all of the Forum solutions with no success ~ even un-installed Outlook 2003 and reinstalled.
It did work for the first month.
I have loaded Desktop Manager (4.7) to both my Laptop and second PC and the sync process works faultlessly on both of these with both Curves.
Weird.

Un-installed DM 4.7 and re-installed ~ CD ~ as original and updated.
Ditto DM v4.7 downloaded from BlackBerry site.
Ditto DM v4.6.
Un-installed Outlook 2003 and re-installed using Contact/Calendar databases as on my Laptop & other PC.
Have tried these Synchronisation error message solutions (and some I can’t remember) from the BlackBerry site and most times when I load DM & connect our Curves ‘Checking for device application updates please wait’ runs and then the previously described error message shows even before Sync button is pressed before I can even get to Configuration.
All 3 PC’s are XP SP2 and are loaded with identical Outlook databases.
As I mentioned also, problem is only with the first machine.

Trying to fit output of XY Graph

Hello, I'm trying to fit the output of an XY graph which is (1-D Array of Cluster of 2 Elements(2x 1-D Array of Double[64-bit Real])). It seems like instead of having one array with two columns X,Y indexed persample number, I want to have a 1-D Array of Column Y , indexed by X. Any ideas?
Thanks.
Solved!

I'm getting NaN on the slope and intercept outputs, is there a way to take the output of the XY Graph Local Variable feed it into the Curve Fitting VI and then add the fitted curve back into the XY graph?
Please attach your VI and some typical data. Most likely one of your points is NaN, in which case the linear fit will fail of course.
You really have some misconceptions. An XY graph is a data sink, and not a data source and faking it with local variables just complicates things.
So what you should do it take the output from the xy express VI, remove the points containing NaN, do the linear fit, and send both to the same xy graph terminal. You only need to write to the graph once.

Thank you & Best Regards

I think this is essentially saying that the Supervisor Assignment is wrong or no longer effective. Looking at your SQL to fetch the Supervisor Assignment there are a number of potential issues. This is what you've currently got:
SELECT person_id
INTO v_person_id
FROM per_all_people_f
WHERE employee_number = r.supervisor_number
AND business_group_id= v_business_group_id;
SELECT assignment_id
INTO v_sup_assignment_id
FROM per_all_assignments_f
WHERE person_id = v_person_id
AND business_group_id = v_business_group_id;
Potential Problems/Clarifications
1. What is r.supervisor_number, what does it contain and how is it derived? I can't see that anywhere else in the block...
2. Is there a chance that r.supervisor_number is referencing an employee who has left, ie, now an ex-employee?
3. The SELECT statement that fetches the assignment_id does not perform any date-effective restrictions, which means you might be lucky enough to fetch the person's current assignment. But you might also fetch an old or future-dated assignment.
4. The SELECT statement that fetches the assignment_id does not restrict the type of assignment, so if this manager has applied for a job (ie, they have an applicant assignment) or some other type of non-employee assignment you might be picking that up.
This would work better for you:
SELECT paaf.assignment_id
INTO v_sup_assignment_id
FROM per_all_people_f papf
,per_all_assignments_f paaf
WHERE papf.employee_number = r.supervisor_number
AND papf.business_group_id = v_business_group_id
AND nvl(papf.current_employee_flag, 'N') = 'Y'
AND trunc(sysdate) BETWEEN
papf.effective_start_date AND papf.effective_end_date
AND papf.person_id = paaf.person_id
AND paaf.assignment_type = 'E'
AND paaf.primary_flag = 'Y'
AND trunc(sysdate) BETWEEN
paaf.effective_start_date AND paaf.effective_end_date;
If it doesn't return a row it means that the supervisor (or whatever employee is returned by r.supervisor_number) is not active as at sysdate and cannot be used. Note that this SQL only applies for employees. If you can have Contingent Workers as supervisors in your implementation then this needs tweaking.
Does that help?

Data inconsistency: posting with restricted transaction type (FAA_POST047)

Hi colleagues!
I have the following error:
Data inconsistency: posting with restricted transaction type
Message no. FAA_POST047
Diagnosis
You are trying to post in company code 1000 with transaction type 130 in ledger group 0N. According to table TABWA, this transaction type is limited. Nonetheless, according to your entries, you want to post to area 11.
System Response
Using limited transaction types is obsolete and would lead to an inconsistent posting in this situation. The system rejects the posting.
Procedure
Use a transaction type that is not limited. And, if possible, choose the ledger group and/or depreciation area on the initial screen.
According to specific accounting we shouldn't post to one of the depr. area, so most of the tr.types are restricted to post to all areas except this one.
Because of this, posting from MM with acc.assignment 'A' is impossible - I have this error.
Any ideas how to solve?
Thanks in advance

Hi Anton
This looks like your transaction type -130 is limited to post only in ledger group-0N as per the transaction type configuration. Due to which system is unable to post all the ledgers and hence this lead to inconsistency.
Please verify the transaction type 130- in configuration T code - OAYA and see if it is restricted by depreciation area (eventually allow to post only ledger group- 0N.
Tcode - OAYA (Limit Transaction Types to Depreciation Areas)
please verify and let us know the update. hope this helps
Best Regards

TA21610 Trying to fit screen size when using 42" tv for Mac mini

Trying to fit screen for Samsung tv. The current view is too large. Tried the system preference display options. It remain to large 42" screen with 1080p 60Hz

If so, select Scaled and try choosing the highest Resolution in the list.

Several curves with several scales on the same graph

Hello,
I am currently working on a project which include a data acquisition VI. I would like to display two curves with two different scales (0 to 1 and 0 to 200) on the same graph.
I have been trying nearly all the options in the properties menu, I can not find anything that corresponds to what I want.
Do you know how to do such a thing?
Thanks in advance,
Gabriel.
Solved!
Go to Solution.

Right click on the existing scale and click Duplicate Scale.
EDIT: I should add that you'll need to set ActYScl through a property node to switch between the difference scales if you want to run operations on them.

Netflix on iPad with restrictions set to only allow "Specific Websites Only"

I have Netflix app installed on my child's iPad. I have restrictions in place on the iPad too - Website restrictions set to "Specific Websites Only".
When I do this the netflix app just spins (never gets to the Netflix login).
If I remove restrictions to allow "All Websites" Netflix works.
I also allowed www.netflix.com as an Allowed Website. Also set Safari "Block Cookies" to never to see if this would help. No luck.
I want Netflix to work, but I also want the restrictions on the iPad to be set to "Specific Websites Only".
Netflix support said (tried them first):
Just spoke with my team who informed me that they have received a few of these complaints. The Netflix app was introduced on the Ipad as a partnership with Apple. We do not have much control over the function of of the permission on the device. They have asked that you reach out to Apple to determine if there is a work around.
Anyone know how to fix this???

hello msreyes,
after countless hours of googling for answers i came up with a solution that works on my situation...it could work for you, its not 100% kids-proof (if your child is tech-savvy then maybe this wont work for you but anyways...)
first step go Settings/ General/ Safari and set your search engine
then Go to Settings/ General/ Restrictions/ Enter your passcode, after you set your restrictions (obviously this step differ from parents to kids age) just for reference here are my screenshots of how i managed the kids phone
ok, so now to the point...next i checked "Limit Adult Content"
and finally you type as many "search engine" and "social media" websites you can possible find. " i know that could be quite allot of URL's but by you having Google as "default serarch enigine and also having www.google.com in th the "NEVER ALLOW" section you kind of take away the "avility" to easly browse Safary,
so say your child types facebook in safari search bar it will show a " website is restricted" message, thus not allowing google or any websites you strict "for that matter" to let your child roam free in the internet world.
and to wrap things up, you can now use Netflix's app in you iPhone. and perhaps your child will never find a walk around glitch..

My passcode is working to unlock the screen but does not work with restriction passcode. Should they be different?

My passcode is working to unlock the screen but does not work with restriction passcode.
Tried it several times but it did not work, though i can use the phone and all features even after 13 failed attempts.
Should restriction passcode be different from what i set?

There is no default restriction password. If you didn't set it someone else may have. If you can't find it then you may have to follow the steps here:
Forgot passcode for your iPhone, iPad, or iPod touch, or ...
Do you have a backup which might not have this restriction passcode? If so restore to that backup?

Sycing a Blackberry Curve with Outlook Calender 2007

Hi I have been trying to sync my BB curve with Outlook, have read all the forums, reinstalled my operating system, downloaded Desktop manager 4.2 and then back to 4.7, upgraded my operating system and I have tried all the applications inside desktop manager including one way, two way, one way from device, one way from computer.
I suspect that there may be a calender entry dialogue box open, so I tried to close and clean everything from the calander on the desk top. The memo, tasks and contacts all syc fine -- when in gets to calender it say "one moment please" and then it does not syc. It does not show up in the sync report as well -- any thoughts

If you are having errors in your Calendar or Address Book on your BlackBerry, and you wish to delete the entire Calendar (or Address Book) database on your BlackBerry, follow the directions below. Make certain you have a good copy of your Calendar or Contacts elsewhere, as this procedure will complete delete ALL Calendar entries and/or Address Book entries on your BlackBerry.
1. Open Desktop Manager on your PC.
2. Open up Backup/Restore > Advanced.
3. From Advanced you'll see a split pane screen. The left pane is what is going to be backed up from your device and the right is a list of the currently existing databases.
3. Highlight on the right side your Address Book database (or your Calendar database) and click the arrow in the middle pointing to the left. This will copy the information over and prepare it for back-up.
4. Once the back-up has completed, hit the Clear button at the bottom to erase and clean out the entire address book database (or Calendar database).
5. After it's finished, it will ask you if you want to save the back-up you've created, say yes and check the device to make sure the address book (or calendar) has been properly cleared out. Now, resync the necessary contact information and you should be set to go.

Edge has very clear restrictions, one being that you must have 6 months of clean payment history which you don't. Either wait until April 14, or good luck at Sprint.
I am unsure how it can be determined the payment mix up was the fault of CS, but regardless, the mix up was done. There can be any number of reasons why a payment could be missed without any fault on your part, however you are still the responsible party for the account and must live with the repercussions.
