• How to specify the precision required to NonLinearCurveFit

  Hi all

  I use the Non linear adjustment method. The method takes all accept the argument of the crieteria judgment. Only the crieteria there is the max iteration. I want the algorithm to iterate until what the quadratic error average of 1E-08 is reached. However it seems that the crieteria exit is hard-coded to be the value of the minimum deviation of function Marit 0.001.

  I work with a very small number here and therefore require very high precision.

  Can someone tell me a workaround to get higher level accuracy (as if the scale would help? if yes, then what is the exact procedure? I tried my way to him but not luck). I have another software (which is a freeware) using who, when I do this adjustment, the residue is minimal (less than 1E-10, quite within my acceptable limits) but when I use the library OR (for which I paid a very high amount) it stops fairly early whithout allowing me to specify the precision desired.

  I know that updates the library would not be that at first, but any idea on no good workaround solution is appreciated.

  And I suggest strongly to it please add this facility throughout the CurveFit library in your future updates. Any professional library must allow the user to decide what level of precision is good enough!

  Its been a week since I posted this question, but not one of the people NOR. SAD!

  However after a long on internet serching, found following link

  http://www.datamaster2003.com/

  For all of you who are stuck with all of CurveFit of NOR and its limits, this is the easiest way to use any type of estimators. Here are the features:

  1. only for linear and Non-linear editing library

  2 user can set thresholds and weights to the settings

  3. the user can define the function by the string expression. So no question of changing the definition of the function to try new possibilities of functions.

  I was very moved with this activeX control which is a FREEWARE. Maybe people NOR should learn how the library should be when they charge astronomical values for Measurement Studio and you give implementations where the user didn't flexibililty even specify the threshold. I guess the majority of implementations of the EMM is better suited for the acedemic only search.

  For commercial uses, this FREEWARE is far more superior as Measurement Studio.

• Using data from the control table

  Hello

  I would like to use the data entered in a table to automate volume/sequence of airflow for a test Chamber. As shown in the screenshot of control table, the first column indicates the number of iterations by elements of array in a series of tests and the second data column specifies the length of each line sequence. Entries in the other columns are specific to different valves and specify values set required in the flow meter.

  

  I guess my question is how can I index/assign each column of the table such that the data to exploit the respective valves are obtained in subsequent iterations all acquire simultaneously with data from other components in the order? While I recognize that the solution may be very simple, I searched on through various examples and messages on the tables and the tables without knocking on a solution. The attached .vi allows me to be a part of the series of tests.

  Best regards

  Callisto

  Hi Callisto,

  If I understand your question then the solution is actually quite simple. The important point to keep in min is the fact that the Table control can actually be treated as an array of string. You can then use all the traditional table manipulation tools and techniques to manipulate your data as you wish. For example, use the Array Index function to retrieve specific columns and then if you want to spend the individual elements in a column in a loop, wire the table until the loop and ensure that indexing is enabled. If you then want to use these data elements to control your test application, you can convert a portion of the resulting string in more useful to digital.

  All these concepts are illustrated in the attached VI. I hope this helps, but let me know if you have any other questions.

  Best regards

• Is the file ' C:\HP\Bin\EndProcess.exe file legitimate?

  I have a month HP g6z laptop with Windows 7, 64-bit.  My anti-virus (Avast Pro) software has identified a file as a virus, but I suspect that it is a legitimate file from HP.  The location/name of the file is: "C:\HP\Bin\EndProcess.exe."  Avast Pro indicates the size of the file as bytes 55 296.  The virus description is that it is a PUP file.

• Envy 15-j101ex: HP Envy 15-j101ex - Windows Pro 10 x 64 - HyperV - startup freeze

  I have a laptop HP Envy 15-j101ex.  It is running 64 bit Windows 10 Pro.  There the last HP BIOS: Insyde F.65

  I need to turn on Hyper-V (hypervisor hyper-V).  I added the Windows features (enabled in the Control Panel Add Windows features): platform Hyper-V and the Hyper-V management tools.

  Work for the Hyper-V hypervisor, virtualization hardware support must be enabled in the BIOS.  The laptop supports hardware support for virtualization.  But when "Virtualization technology" is enabled in the BIOS (with active UEFI), it ends with a freeze on startup with the circle of rotation (under the logo of HP) and the laptop won't boot.  Virtualization technology must be in the OFF position or the will of the laptop does not start.

  I checked on the Microsoft site and ran the tools proposed: coreinfo.exe, check the SLAT, DEP status checked.  Everything on the laptop is as specified in the requirements for Hyper-V.

  > - what someone faced this problem?

  > all suggested fixes?

  Note: I've seen suggestions to turn Bluetooth off and uninstall the driver. But if I uninstall the Bluetooth drivers, Windows will automatically reinstall the Bluetooth drivers after a reboot. And if the BT device is just disabled in Device Manager (without uninstalling drivers), problem (defective start).

  Thank you very much!

  GH

  Problem finally solved manually!

  Cause: Windows 10 and HP site give BAD (old) version of the Mediatek (Ralink) drivers for this laptop HP Envy (15-j101ex).  Had to manually search for drivers updated on ALL HP websites.  And after many wasted hours (trying to locate the drivers and trying to disable bluetooth constantly) found the Mediatek drivers updated.  Please see the links below.

  Solution:

  Download the drivers for the adapter Mediatek Wireless LAN RT3290:

  http://h20564.www2.HP.com/hpsc/SWD/public/detail?swItemId=ob_150624_1#tab3

  Download drivers for Mediatek Bluetooth adapter RT3290:

  http://h20566.www2.HP.com/hpsc/SWD/public/detail?swItemId=vc_159313_1#tab3

  Install the drivers and then turn it ON "Virtualization technology" in the BIOS and you should be good to go!

  HP support could be more USEFUL:

  The web site for this laptop should provide access to the latest drivers for Windows 10.  And the database of drivers window must be updated so that Windows 10 provieds the LATEST drivers for HP laptops.

• Best laptop for work with Adobe CC

  I'm about to buy a new laptop. I did some internet research on what is a good laptop to work with the software Adobe CC. I'm having a hard time getting a response. Does anyone have suggestions on what laptop to get that works with all of the suite No. or minimum questions? I heard that the Nvidia driver has problems with Adobe. That of just 10 Windows or is it ok for Windows 8? I hate to get an older version when a new version is released, any suggestion that someone can provide would be appreciated. Although you can specify what system requirements I should look for. It must be that this laptop to last me for a while, so I don't want to get something that is obsolete in a year or two.

• Default sort of the classic report does not seem to work

  4.2.1

  THM 2

  I have a classic report consisting of an underlying sql with 3 unions. The columns include a party_name (varchar) and two numeric fields.

  for example only select total_cost, cost_to_company, party_name, apex_item.checkbox2(1,party_id)

  (

  Select a.party_id, a.party_name party_name, a.cost_to_company, table a.total_cost when certain conditions

  Union

  Select a.party_id, a.party_name party_name, a.cost_to_company, table a.total_cost when certain conditions

  Union

  Select a.party_id, a.party_name party_name, a.cost_to_company, table a.total_cost when certain conditions

  )

  In our real-world scenario, these three applications are on different tables and different even if some elements are all the same (including the type of data, etc.), where the union

  Because I need activate sorting using the report attributes. I put the tri reporting attributes such as 1 - total_cost desc, 2 - Party_name growing.

  However, when we run the report, if the total_cost for different parts is 0, the sorting should be based on party_name. That does not seem to happen. It still sorts out randomly. I'm wonderingm if it's because there are trade unions and no order of in the query.

  No idea how to solve this problem?

  Nothing to do with unions.

  It looks like it is connected to your thread previous marking dynamically of columns in a "BOLD" for the highest value report. Is it? If so, where are the links generated to conditionally and other HTML elements? They are more likely to cause sorting problems. Instead of posting question after question about one aspect of the problem after another, you get a solution much faster together by creating an example on apex.oracle.com and specifying the complete requirements.

  That shouldn't be the case. You could try to encode like this; where you only use the DeleteRow when you press the OK button and not when you press the checkbox. Be sure to include the step - 1, otherwise it will fail anyway.

  ON FIELD CHANGE OF CHECK BOX :
  
  If MY_RECORD.CHECK_BOX_FIELD = "Y" Then
  GROUPBOX.Visible = False;
  &myRowset.HideAllRows();
  Else
  GROUPBOX.Visible = True;
  &myRowset.ShowAllRows();
  End-If;
  
  ON FIELD CHANGE OF MY OK BUTTON :
  
  &myRowset = GetRowset(Scroll.MY_GRIDRECORD);
  If MY_RECORD.CHECK_BOX_FIELD = "Y" Then
  For &i = &myRowset.ActiveRowCount to 1 Step -1
  &myRowset.DeleteRow(&i);
  End-For;
  End-If;
  
  /* Save and do further processing */
  

• I bought are 11 and it will not be installed

  I have a cd - rw drive.  your needs said that Windows XP with service PAC 3 will accept installation.

  the installation disk will work on my CD player - RW.

  The software package should specify the minimum requirements for installing the software.  If she says a DVD - ROM drive is required (minimum), then it is likely that your CD drive that can be used.  You will probably need to download the software and then activate it with the serial number you received with the CD.

  I'm not familiar with what ARE 11, but you should be able to find available for download in the pages of Adobe products if there is a new version.

• NOT NULL is maintained

  Hello
  
  My question is simple.
  
  Why when I create a table using CREATE TABLE... LIKE the SELECT statement, the NOT NULL constraint is maintained in the new table?
  If this is the default behavior, how to disable?
  

  SQL> desc employees
   Name                                      Null?    Type
   ----------------------------------------- -------- ------------
   EMPLOYEE_ID                               NOT NULL NUMBER(6)
   FIRST_NAME                                         VARCHAR2(20)
   LAST_NAME                                 NOT NULL VARCHAR2(25)
   EMAIL                                     NOT NULL VARCHAR2(25)
   PHONE_NUMBER                                       VARCHAR2(20)
   HIRE_DATE                                 NOT NULL DATE
   JOB_ID                                    NOT NULL VARCHAR2(10)
   SALARY                                             NUMBER(8,2)
   COMMISSION_PCT                                     NUMBER(2,2)
   MANAGER_ID                                         NUMBER(6)
   DEPARTMENT_ID                                      NUMBER(4)
  
  SQL> create table emp as select * from employees;
  
  Table created.
  
  SQL> desc emp ;
   Name                                      Null?    Type
   ----------------------------------------- -------- ------------
   EMPLOYEE_ID                                        NUMBER(6)
   FIRST_NAME                                         VARCHAR2(20)
   LAST_NAME                                 NOT NULL VARCHAR2(25)
   EMAIL                                     NOT NULL VARCHAR2(25)
   PHONE_NUMBER                                       VARCHAR2(20)
   HIRE_DATE                                 NOT NULL DATE
   JOB_ID                                    NOT NULL VARCHAR2(10)
   SALARY                                             NUMBER(8,2)
   COMMISSION_PCT                                     NUMBER(2,2)
   MANAGER_ID                                         NUMBER(6)
   DEPARTMENT_ID                                      NUMBER(4)

  Here are the rules of article 10.2 SQL Reference CREATE TABLE:

  >
  Oracle database derived from lengths and data types of the subquery. Oracle database follows the following rules for integrity constraints and other attributes of column and table:

  *

  Oracle database automatically sets on the columns in the new table as any NOT NULL constraints that have been created explicitly on the corresponding columns of the table selected if the subquery selects the column rather than an expression that contains the column. If the lines that violate the constraint, then the database does not create the table and returns an error.
  *

  Constraints NON NULL created implicitly by the Oracle database on the selected table columns (for example, for primary keys) are not carried over into the new table.
  *

  In addition, check, primary keys, unique keys, foreign keys, constraints criteria for partitioning, index and default column values are not carried over to the new table.
  *

  If the selected table is partitioned, you can choose if the new table will be partitioned in the same way, differently partitioned or not partitioned. Partitioning is not included in the new table. Specify any partitioning required as part of the CREATE TABLE statement before the AS subquery clause.

  >

  You can try the following:

  SQL> create table s(x int null, y int not null);
  
  Table created.
  
  SQL> create table t as select * from s;
  
  Table created.
  
  SQL> desc t;
   Name                                      Null?    Type
   ----------------------------------------- -------- ----------------------------
   X                                                  NUMBER(38)
   Y                                         NOT NULL NUMBER(38)
  
  SQL> drop table t;
  
  Table dropped.
  
  SQL> create table t as select x, y+1-1 as y from s;
  
  Table created.
  
  SQL> desc t;
   Name                                      Null?    Type
   ----------------------------------------- -------- ----------------------------
   X                                                  NUMBER(38)
   Y                                                  NUMBER
  

  Or with character data types:

  SQL> create table s(x varchar2(10) null, y varchar2(10) not null);
  
  Table created.
  
  SQL> drop table t;
  
  Table dropped.
  
  SQL> insert into s values('a', 'b');
  
  1 row created.
  
  SQL> commit;
  
  Commit complete.
  
  SQL> create table t as select x, y || '' as y from s;
  
  Table created.
  
  SQL> desc t;
   Name                                      Null?    Type
   ----------------------------------------- -------- ----------------------------
   X                                                  VARCHAR2(10)
   Y                                                  VARCHAR2(10)
  
  SQL> select * from t;
  
  X          Y
  ---------- ----------
  a          b
