What is Averaging Time & Data Reduction Factor in Frequency-Weighted Acceleration?

I have to analyse the Ride Comfort Data of one vehicle (as per ISO2631-1). It has Acceleration levels of driver seat in X, Y, Z directions.
I need to plot Frequnecy Weighting in dB vs Frequency in Hz. Data is recorded at 500 Hz for 9.95 secs.
How much Averaging time & Data Reduction Factor should i take and how to convert them in as above said graph.

In ISO2631-1 it says that while analysing the data you should take weighing factors for seating condition. For driver seat it is 1 it is also mentioned in Frequency Weighted Averaging in Diadem as Wk & Wd etc in signal analysis.
Output should come as Frequency weighted RMS of individual X, Y , Z and combined RMS of X, Y , Z. for that i need to know the "Averaging Time Constant Required" & Data Reduction Factor. As changing any of these will change the results.
I need to have one final RMS value of X, Y, Z representing the ride comfort of that vehicle & If possible combined RMS too.
And how to change that value to dB. I know how to do it manually by taking a reference value and taking log with base 10 by dividing by reference value.

Data reduction - setting factor in program

Is there a possibility to set the data reduction factor of the data reduction Express VI in the program and not only in the settings of the Express VI itself ?

The only way at present to pass a value to an Express VI is to convert it to a normal VI and then add an input pin to the connector terminal.

Hi,
Real-Time Data Acquisition BI 2004s
Real-time data acquisition supports tactical decision-making. It also supports operational reporting by allowing you to send data to the delta queue or PSA table in real-time.
You might be having complex reports in your BI System, which helps in making decisions on the basis of data of your transactional system. Sometimes (quarter closure, month end, year ending...) single change in the transactional data can change your decision, and its very important to consider each record of transactional data of the company at the same time in BI system as it gets updated in the transactional system.
Using new functionality of Real-time Data Acquisition (RDA) with the Net Weaver BI 2004s system we can now load transactional data into SAP BI system every single minute. If your business is demanding real-time data in SAP BI, you should start exploring RDA.
The source system for RDA could be SAP System or it could be any non-SAP system. SAP is providing most of the Standard Data Sources as real-time enabled.
The other alternative for RDA is Web Services, even though Web Services are referred for non-SAP systems, but for testing purpose here I am implementing Web Service (RFC) in SAP source system.
Eg will be a production line where business wants information regarding defective products in the real time so that production can be stopped before more defective goods are produced.
In the source system, the BI Service API has at least the version Plug-In-Basis 2005.1 or for 4.6C source systems Plug-In 2004.1 SP10.

TDMS time based reduction method has no end date

Hello TDMS experts,
I am in the process of configuring the 'Time based reduction' method of TDMS. In the package, I am in phase "System Analysis"->"Analyze and specify'from date'".
Here it gives me the option to specify the start/from date only. If I want to transfer data for only a month in the past lets say april of 2007, then how can I specify the from and to dates.
Please advise.
Thank you,
kind regards,
Zaheer Shaikh

Hi Pankaj,
Thanks for the reply.
In the phase "maintain Table Reduction" I have chosen SAP standard reduction, that means the table reduction is handled by SAP itself. Since my sender system database is 4 Terabytes, my question is if I select the 'from date' as 10th April 2009 (present date is 20 April 2009), will the TDMS still copy the whole tables for which I have not manually defined any reduction?
Please advice.
Thank you,
Kind regards,
Zaheer Shaikh

Data migration completed what about next time

Hi Guys,
I have sucessfully migrate the data into a new system from our existing Quality server, this is just for testing the tdms implementation, but my question is what about next time, suppose i have migrated all the data from 1.08.2007 to till date and package has been completed, but when we start again we need to create another package i guess and if we need to change only the data selection date then do we have to go for all the step or is there any selective option for us.
Regards
Subhash

Hi,
Please see the help file. Here is an extract:
If no changes regarding the definition of the objects for transfer have been made, you can create a refresh package to replace the data in the receiver system with current data from the related sender system. You can specify a new 'from-date' for the time-related approach and include additional tables in the transfer.
The refresh package inherits the setting of the related configuration package, which means that you do not have to execute some of the steps that were required for configuration.
Procedure
Place the cursor on the related configuration package, and choose Copy for Refresh.

Sales orders in TDMS company/time based reduction are outside the scope

Guys,
I have had some issues with TDMS wheras it didn't handle company codes without plants very well. That was fixed by SAP. But I have another problem now. If I do a company code and time based reduction, It doesn't seem to affect my sales orders in VBAK/VBUK as I would have expected. I was hoping it would only copy sales orders across that have a plant which is assigned to a company code that was specified in the company code based reduction scenario. That doesn't seem to be the case.
VBAK is now about one third of the size of the original table (number of records). But I see no logic behind the reduction. I can clearly see plenty of sales documents that have a time stamp way back from what I specified in my copy procedure and I can see others that have plant entries that should have been excluded from the copy as they do belong to different company codes than the ones I specified.
I was under the impression that TDMS would sort out the correct sales orders for me but somehow that doesn't seem to be happening. I have to investigate further as to what exactly it did bring across but just by looking at what's in the target system I can see plenty of "wrong" entries in there either with a date outside the scope or with a plant outside the scope.
I can also see that at least the first 10'000 entries in VBAK in the target system have a valid from and to date of 00.00.0000 which could explain why the time based reduction didn't work?
Did you have similar experiences with your copies? Do I have to do a more detailed reduction such as specifying tables/fields and values?
Thanks for any suggestions
Stefan
Edited by: Stefan Sinzig on Oct 3, 2011 4:57 AM

The reduction itself is not based on the date when the order was created but the logic enhances it to invoices and offers, basically the complete update process.
If you see data that definitely shouldn't be there I'd open an OSS call and let the support check what's wrong.

Undo file Having huge read average time more than 20ms

Please,
I'm working on oracle 10g, windows server 2003.
From the file I/O stats, I found that the Average read I/O from the undo files is more than 20ms, this contrast with other files where the same I/O metric is less then 0.5ms.
Can someone give me a clue?
thanks a lot

I assume 'undo files' you mentioned means datafiles of undo tablespace: Yes
How did you determined the I/O metric ? What tools used?, the following script
column FILE_NAME format a30
column PHYRDS format 999999,999
column PHYWRTS format 999999,999
column READTIM format 999999,999
column "READ AVG (ms)" format 999.99
column "TOTAL I/O" format 999999,999
select
FILE_NAME,
PHYRDS,
READTIM,
PHYWRTS,
READTIM / (PHYRDS + 1) "READ AVG (ms)",
PHYRDS + PHYWRTS "TOTAL I/O"
from
V$FILESTAT a,
DBA_DATA_FILES b
where
a.FILE# = b.FILE_ID
order by
6 DESC;
Are other files on the same storage as undo datafiles?, all files datafiles,redo files, cotrol files are on the same storage.
How are your disk storage configured?, it may be a RAID X technology, because the level is unknown.
By default our client cannot accept to move the undo file to another storage, that's why all data files are stored on the same drive.
So what can cause the undo read average time to be so high?
Thanks again

TDMS - time based reduction - receiver system deletion

Experts,
I'm doing a time based reduction. I'm on the step "Start Deletion of Data in Receiver System". It's been running for over 18hours.
But I don't see any jobs running in SM66 on the Central/Control or Sender or Reciever systems.
When I click on the "Task" button, I see it has completed 8,444 of 12,246 sub activites. There are 3,802 not yet started.
We're on all the latest levels of DMIS and ECC.
Any ideas?
Thanks
NICK

Ashley and Niraj,
Hey, I'm all for tips/tricks so don't worry about messing up my thread.
I completely shut down the central/control system via stopsap and restarted. Still it was in "running" status but no jobs were running on sender/rec or central/control.
So I tried the trouble-shooting but it was un-clear to me what to do.
I ended up highlighting the phase I reference earlier, then doing "execute" again. The status changes from the "truck" to a green flag and I started to see jobs run again on the receiver system. Again they have stopped, but I see another job scheduled to run in a few minutes....It's just weird, I didn't run into this on my last time-based copy.
I'll post a few things I've learned to increase performance:
RDISP/MAX_WP_RUNTIME = 0
At LEAST 25 WP and 25 BCK procs

RDISP/BTCTIME = 60

Calculating average time from two records from the same table.

Hi all
I need to calculate the average time between two events that are recorded in the same table.
The table is TMS_MESSAGE_AUDIT_LOG
MESSAGE_ID VARCHAR2(16 BYTE) NOT NULL,
MESSAGE_VERSION NUMBER(2) NOT NULL,
CREATE_TM VARCHAR2(18 BYTE) NOT NULL,
MESSAGE_STATUS VARCHAR2(30 BYTE),
TRANSACTION_TYPE_NM VARCHAR2(30 BYTE),
MESSAGE_TP VARCHAR2(3 BYTE),
WORKFLOW_OBJECT VARCHAR2(30 BYTE) NOT NULL,
WORKFLOW_REQUEST VARCHAR2(30 BYTE) NOT NULL,
WORKFLOW_RETURN_CD VARCHAR2(30 BYTE) NOT NULL,
AUDIT_ACTION VARCHAR2(255 BYTE),
LAST_UPDATE_USER_LOGON_ID VARCHAR2(12 BYTE),
LOCAL_TM VARCHAR2(18 BYTE) NOT NULL,
LOCAL_TIME_ZN_NM VARCHAR2(70 BYTE) NOT NULL,
LOCAL_DAYLIGHT_IN CHAR(1 BYTE) NOT NULL,
FPRINT VARCHAR2(30 BYTE)
What i now need is
When the MESSAGE_ID is the same i need have the average time between when the MESSAGE_STATUS is AA and BB ( I need the time out of the CREATE_TM field )
And this for every 15 minutes interval.
Because this table will become BIG millions and millions of records it needs to be fast.
Can anybody help me.

Graphing Time Data

I have a report that pulls data from a phone system database. Each record has the amount of time spent talking, waiting, holding and ringing for each person as numeric fields showing the total number of seconds for a block of calls. I've been able to create the report and write formulas that convert the seconds for each field into a time field. But of course it converts it to a specific date which is not what I really want. If they run the report for a large time period like a month, then there will likely be more than 24 hours in the hour position which the function trucates to a single day.
As a work-around I've been able to use formulas to calculate the number of hours/minutes/seconds and then create more formulas to calculate the summary and grand totals for each person. Not the best solution, but it works. My problem is that now they would like to add a graph to the report showing the average total time spent on the phone for each person.
Of course I can't graph my calculated time since the formulas result in a String value. And it doesn't seem to want to let me sum a time field so I can graph a true time value either. I thought maybe I could convert my finished average time per person into a time value at the group level since that wouldn't be over 24 hours, but that didn't work either.
Was hoping someone would have some experience in working with time data. Any suggestions would be helpful.

Hi Jay,
Thanks for the response, but I don't think I explained my problem clearly. Here's how my data is stored (sorry about the lack of columns, so I separated them with "|"):
Phone Rep ||   Day   ||   Talk Time ||   Hold Time || Total Time
John Doe   ||    1-1-09 || 5,000 sec||   1,200 sec   || 6,200 sec
John Doe   ||    1-2-09 || 6,000 sec || 2,000 sec ||   8,000 sec
Total          ||             11,000 sec || 3,200 sec || 14,200 sec
The read out on the report should read:
Phone Rep   ||   Total Talk Time ||   Total Hold Time || Grand Total Time
John Doe      ||     3:03:20       ||          0:53:20       ||        3:56:40
Avg/day        ||     1:31:40         ||        0:26:40          ||     1:58:20
When I convert the time in seconds to a time variable with TimeSerial(hh,mm,ss) it gives me the time in the correct format, but it's listed as simply a time of day. If the report runs for many days, then the time values could require the hours to go over 24 such as 155:35:26 to reflect a month's worth of calls. My formulas that calculate the read out as shown above can do this with no problem. The problem occurs when I try to graph the average at the bottom. I can't seem to find a way to chart the average time per day.
I've tried summing the total time in a group and then find a way to format the y axis to show the time format. I've tried creating a formula to convert the individual record into a time format and then summing that for the graph, but it doesn't give me the option to sum, only to count or other non-numeric options. I've also tried creating a formula to convert the finished average calculation into a field that can be graphed by itself, but when I insert the chart it doesn't list my formula in the available fields to graph.
I would even be willing to create the chart in a sub report that somehow pulls in just the total average and then tries to graph that, or use the Microsoft OLE chart object to try and push the data to that and insert the finished chart, but having never done either of these, I was hoping for an easier solution.
Thanks
