Counting the number of cycles

I have a program that runs until the stop button is pressed taking readings every xx seconds. I would like to display a number that counts haw many readings have been taken. I see that there is an accumulator that will add 1 to a number, but how do I start it off and keep it going?
Thanks, Ringo

Either use a shift register initialized to zero or wire the increment function to the iteration terminal of your while loop. I've attached a picture that shows both methods.

How to count the number of cycles in sine wave

Hi,
I am new to Labview. I have labview 8.2 version and my dataacquisition is NIDAQPAD6015. I could write a program to generate a sine wave of desired frequency through simulate signal. My question is how do i measure the number of cycles for this sine wave as soon as I run the program. Hope my question is clear.
Ravi Mokirala

To find the offset (which in this case is the Y value midpoint around which the sine wave is symetrical):
Capture more than one cycle. Find the min and max values. Subtract Min from Max and divide by 2. Then subtract this result from the Max value (or add the result to the Min value). This is the offset.
To count the number of cycles where the offset is unknown, just use the first data point value as a reference. If the next data point is more positive, then count the number of times that the first data point is repeated and the next data point is more positive. Of course with DBL data type, you probably would not get the exact same value as the first data point, so you need to use In Range with a very tiny limit. It all depends on your signal amplitude, frequency, and sampling rate.
Example: Lets say your first data point value is 0.5 and the 2nd point is 0.55. You need to look for another value that is between 0.48 and 0.52. Then read the very next data point value. If it is greater than the previous value, add one to the cycle count. If it is less than, you are at half a cycle, do not add to the count.

How to improve the number of cycles on my MBA

What is better to charge you MacbookAir every time you can find power or just when the battery is totally discharged? I need to know how to improve the cycles of my battery

I would really like to avoid reducing the number of cycles
Actually... you probably want to reduce the number of cycles, not "avoid" reducing the number of cycles. As CW mentioned, you probably don't need to worry too much about your cycles and you should just generally use your MacBook Air as you need to. However, if you want to prolong your battery life, you should run it plugged in the majority of the time. You should not run the battery all the way down before recharging it again. It is necessary to do this when calibrating the battery, but this is something which only needs to be done ever few months:
http://support.apple.com/kb/ht1490
The more you run on battery, the more your cycle count will go up. In general, going through a cycle or so a week is a good minimum. A cycle is a full discharge and then full charge of your battery. So... if your battery is at 100% and you let it discharge to 0% and then fully charge it back up to 100% again, that would be once cycle. Likewise, partial discharge & recharges count as partial cycles. For example, if your battery were at 100% and you let it discharge to 90% and then recharged it back up to 100%, that would be 1/10th of a cycle. You would need to do that 10 times in order for it to count as one cycle. So, you can see that you will increase your cycle count much faster the more you allow your system to run on battery before recharging it.
These are really just general guidelines. There may be times when you're just not by a power outlet so you have no choice but to run your battery down. Regularly doing this will shorten the overall life of your battery. But, once in a while will have little impact.
Here are Apple's guidelines for battery care:

Is there a way to count the number of times an array moves from positive to negative?

I have an array of values, and I need to find the number of times that the array changes signs (from positive to negative, or vice versa). In other words from a graphical standpoint, how many times a certain line crosses the x-axis. Counting the number of times the array equals zero does not help however, because the array does not always equal exactly zero when it crosses the axis (ie, the points could move from .1 to -.1).
Thanks for you help. Feel free to email me at [email protected] I only have lv 5.1.1 so if you attach any files, they cannot be version 6.0.

Attached is a VI showing the # of Pos and Neg numbers in an array, with 0 considered as non-Pos. It is easily modifiable to other parameters - including using the X-axis value as your compare point versus only Zero.
This is a modified VI from LV (Separate Array.vi)
Compare this with your other responses to find the best fit.

How do I count the number of records returned in the CMIS query

How do I count the number of records returned in the query CMIS?
SELECT COUNT(*) FROM ora:t:IDC:GlobalProfile WHERE ora:p:xRegionDefinition = \'RD_PROJETOS_EXCLUSIVOS\''}
Euler Homero

Hi Euler,
interestingly enough, the reference guide for CMIS ( http://wiki.alfresco.com/wiki/CMIS_Query_Language ) that I found does not mention the COUNT function at all. On the other hand it states that: "The SELECT clause identifies which virtual columns to return in the result set. It can be either a comma-separated list of one or more queryNames of properties that are defined by queryable object types or * for all virtual columns."
There are, however, some other posts like e.g. http://alfrescoshare.wordpress.com/2010/01/20/count-the-total-number-of-documents-in-alfresco-using-sql/ which state that they could make it working.
Having asked in the WebCenter Portal forum, I assume that your content repository is WebCenter Content. The CMIS doc for the Content is available here: http://docs.oracle.com/cd/E23943_01/doc.1111/e15813.pdf (no COUNT there either). It does, however, mention explicitly that "CMIS queries return a Result Set where each Entry object will contain only the properties that were specified in the query.". This means your could rather investigate the Result Set. Note that there are also other means than CMIS how to get the requested result set (e.g. calling a search service directly via so-called RIDC).
In the given context I am also interested what your use case is. OOTB CMIS in WebCenter Portal is used, for instance, in Content Presenter, where it is content rather than "parameters" what's displayed.

How to count the number of rows in a resultser object?

hi there
how to count the number of rows in a resultser object which may contains millions of rows? besides using a while loop? thanks

You don't, you execute a query whose result is the record count of those records that match the search and then you execute the actual query to create your record set. Typically you do
select count(id) from YourTable where [filter]
from the resulting ResultSet do
int res.getInt(1);
which gives you the count and then
select id from YourTable where [filter]
to produce the actual result set.
in the second query the id part can be substituted with the actual fields you want.

How to Count the number of TAB chars value '0A' in a line?

I have a requirement to count the number of TABs in a text file that I am processing (they must equal 75) to ensure that all the fields have been submitted on the file I am reading?
How do I identify the TABs in a line?
I have this so far:
         CONCATENATE gv_unix_file gv_lstfiles-name INTO gv_unix_file.
          OPEN DATASET gv_unix_file for INPUT IN TEXT MODE ENCODING NON-UNICODE.
          IF sy-subrc <> 0 .
            message e000(zz) with 'Cannot access in_uk files'.
          ENDIF.
          CONCATENATE gv_unix_file_arc gv_lstfiles-name INTO gv_unix_file_arc.
          OPEN DATASET gv_unix_file_arc FOR OUTPUT IN TEXT MODE ENCODING NON-UNICODE.
          IF sy-subrc <> 0 .
            message e000(zz) with 'Cannot access in_uk files'.
          ENDIF.
          DO.
            READ DATASET gv_unix_file into lv_str.
            IF sy-subrc <> 0.
              exit. "exit do loop, file is done.
            else.
              TRANSFER lv_str to gv_unix_file_arc.
            ENDIF.
          ENDDO.

Here is a sample code:
DATA: lv_string TYPE string,
      lv_tab TYPE c VALUE cl_abap_char_utilities=>horizontal_tab,
      lv_i TYPE i.
DATA: result_tab TYPE match_result_tab.
DO 3 TIMES.
CONCATENATE 'A' lv_string INTO lv_string SEPARATED BY lv_tab.
ENDDO.
" this is how you need to find how many tabs are in your transfer work area...
FIND ALL OCCURRENCES OF lv_tab IN lv_string RESULTS result_tab.
DESCRIBE TABLE result_tab LINES lv_i.
WRITE:'No. of tabs found:', lv_i.

Counting the number of IDocs in a package of IDocs in BPM

Hello All,
I need a solution where I need to count the number of EDI_DC40 segments (The IDoc Count) in a package of IDoc's. The following is the scenario
1) We are receiving a package of IDoc's in receive step using the XI File Adapter. I was wondering if there is a way that I can count the number of IDoc's in the BPM using a container operation or some other Method. I appreciate any help.
Thanks.

HI,
We have two ooptions,
one as explained above , yu can use standard count function and that can be used.
Second one is we have count option in file adapter to count the msgs.

Count the Number of Rows in Data form

Hi,
I want to count the number of rows in a data form.In my form there is a large number of rows.Is there any way to count it.
Thanks.

If you are on 11.1.2.x then you could look at adding a formula and using the CountA function - http://download.oracle.com/docs/cd/E17236_01/epm.1112/hp_admin/apcs03s06.html
Otherwise it would be possible using custom javascript which you would have to had some experience in using.

Count the number of rows in a workbook.

Hi Experts , I have a requirement to count the number of rows in a WorkBook.Will it be possible to do this by creating a KeyFigure?Or are there any options in BEx to count and display the number of Rows.Many thanks for all your help.

Hi
In the query create a calculated key figure called 'Count' and put a formula as =1, then use this count where ever applicable..you can very well count the no. of rec.
with this.
Hope this helps..
assign points if useful..
Cheers,

does anyone know of any function module by which we can count the number of digits in a field.
Say i have a priority field which is numc2, and the the user fills in a 5 digit number in it, i was to calculate this and raise an error if the number of digits is more than 2.
Thanks in advance.
charu.

data : text(10),
len type i.
text = <your variable which user is passing>
len = strlen( text ).
if len gt 2.

How count the number of substrings in a string

Hi all,
I wonder if someone can help me and point out where I'm going wrong.
I want to count the number of substring starting with 'd' and ending with 'e' in a string supplied by a user.
currently my code is only counting the number of 'd' and 'e' characters in the string.
    public static void main (String [] args)
         Scanner input = new Scanner (System.in);
         String mstring;// string variable that the user will enter
         int i = 0; // upstep variable
         int count = 0; // int variable to count the number of substrings
         System.out.print("Enter a string: ");
         mstring = input.nextLine();
         while (i != mstring.length())
                   if(mstring.charAt(i)=='d'){count++;}
                   else if (mstring.charAt(i)=='e'){count++;}
                   i++;
         System.out.println("The total d e substrings is " + count);
}For example if the user enters adbedeaadffe the total number of substrings should be 5 but I'm getting 6 as the program is just counting the number of times it comes across 'd' and 'e'
Can anyone shed some light on this for me thanks.

Hi all I had a good few replies to this question but they seem to have been removed from the system for some reason.
I've changed my code slightly and it works but only for one round of the guard.
               Scanner input = new Scanner (System.in)
         String mstring;// main string variable that the user will enter
         int i = 0; // upstep variable
         int count = 0; // int variable to count the number of substrings
     System.out.print("Enter a string: ");
         mstring = input.nextLine();
         int y =mstring.length();
         while (i != mstring.length() && y !=0)
         if (mstring.charAt(i) == 'd' && mstring.charAt(y-1)=='e'){count = count+1;}
         y--;
         i++;
         System.out.println("The total a b substrings is " + (count));The above code will only print out one substring of adbedeaadffe but that is not what I need, I need to be able to print out all of the substrings.
Can anyone tell me where I'm going wrong.
Thanks in advance
