Creating a cosine filter and signal mixer

I am new to Labview, so my questions might be quite simple for some of you (I hope) There are 3 things I need to do...
1) use a MATLAB m-file which generates a sampled high-frequency signal as a source
2) take the signal and mix it with another signal (at the high frequency) to shift it to baseband
3) make a cosing filter, preferably tuneable
Any references and suggestions you could suggest for any or all of these points would be greatly appreciated.
Cheers.
-Ben

Answered my own questions in part now through experimentation...
1) The vi used to include Matlab scripts is found in "Function>Analyze>Mathematics>Formula".
*NOTE: If your m-file contains a function rather than just a script, just type the function call in the Labview Matlab script box, having added the path to your m-file in your copy of MATLAB.
I couldn't get it to pass a text string to the input of a matlab script box, but got round that one...
3) using the convolution vi from the "Functions>Analyze>Signal Processing>
Time Domain" palette seems to produce the desired digital signal filter I wanted (when convoluted with the correct taps which someone else thankfully had...)

Create a resource filter and add/redefine a property value to a resource?

Hello,
I need an advice how to create a resource filter and add a property to a resource. I already created the project and after creating myfilter.java automatically by using the "Service, filter and scheduler taks generation" in my developer studio, there's a filter() method where the filtering has to be implemented. Here I need an example how to read the resource path and add or redefine a property value. (In this case the property value depends on the resource path) So I also need to know, how to get the ressource path. Can anybody please support me with some example code?
Thanks in advance
Cheers

Can new PWA views be created whereby a filter can be set and associate to the view by default? (Project Server 2013 ONLINE)

My main question is: Can new PWA views be created whereby a filter for that view can be set, and associate to the view by default? (Project Server 2013 ONLINE)? and can I have a filter set to filter on person logged on to...
In previous versions of Project Server, when CREATING a PWA view, we were able to apply/ define a filter for that view. Does not seem like it is the case in Project Server 2013 Online. And if I remember, we could also use the URL Guid_view_id.
Please confirm; and / or tell me how-to.
What I was hoping to do is the following... Given that our standard that we have adopted for reporting time is 'My Timesheets' (fyi, Single Mode Entry=ON), we have some resources who have others who do it on their behalf via 'My Tasks' (ie., accomplished
by using the 'Assignment Owner' field, accordingly). Therefore, when entering time on someone else's behalf within 'My Tasks', we like to present the user that is logged in only the tasks that they are are assigned to update on others' behlaf.
I know that there is another more elegant approach to doing this which may be to use the Delegation feature. But since we are trying to stick to Sharepoint Security mode for now, this is not an option for the time being.
Any help appreciated would be greatly appreciated.

Hi Spiro,
1- You still can define in Project Online a filter in the view settings, it is located just above the category setting. Here is a screenshot of the summary project center view:
2- The view GUID is not anymore in the URL, since the URL triggers an action only on the webpart and not on the whole page. I agree this is annoying since it was great to send a URL with a specific view.
3- Concerning the access to my timesheet versus my task, I'm not sure to get a full understanding but on a general way, it is much more easy to deal with those situation using categories which you cannot do with the SP permission mode.
Hope this helps,

Create prompt with date-filter and initialize it with current date

Oracle BI 11 g
Hi!
I need to create dashboard prompt with date-filter and initialize it with current date. How can I do that?
I tried to create repository initialization block and add variable. But I don't know what should I write to DataSource? I tried to use functions Now(), Current_Date, sysdate (for example, SELECT Now() FROM tbl_Calendar) but without results - when I pressed "Test..." button I got errors - something like "Now() is unknown function" or "Incorrect syntax near key word Current_Date".
After that I tied to use Presentation Variable in Prompt, but also without success ((
Please, help me.

I've created Repository Variable "CurrentDate", using SQL-query like this "select convert(varchar(10), getdate(), 104)" and now this variable is being initialized by value "07.04.2011". But I don't understand how to use this varible in DashboardPrompt! What item in list "Default selection" I should choose - "Variable Expression", "Server Variable" or something else? When I chose "Variable Expression" and write "CurrentDate" I got just string "CurrentDate" when preview Prompt. @{CurrentDate} gave me the same result.

How to create a custom report and include multiple extended CRM database?

I have created a number of CRM databas extensions and applied all there fields to my contacts and cases.
I might have for example:
- Additional address details
- Business information
- Quote Details
- Trade Referees
I know how to run a custom report and that I can select any one of these extra CRM databases as a filter and included them in the report. Is there a way though to add more than one (preferrably all) of the extra CRM databases to the report?
The onely ways I can see it work is by either include all fields in one extra CRM database (not ideal) or bu running multiple reports and merge them somehow in Excel.
Is there another way that I am not aware off?
Thanks for your help,
Jerun

Hi Jerun,
There's no way to do that. You'll need to run separate reports and merge them in Excel.

How can I create a search filter on my muse project?

How can I create a search filter on my muse project like the 'sort by' function of this website? http://trufcreative.com/work
By that I mean be able to narrow down the content displayed on a single page (preferably with an animation) without having the switch pages or reload the browser.
I'm assuming this isn't something Muse can do natively, but if anyone knows the code, and how to make it work with Muse, that would be awesome.
Cheers!

Do you really need to put "tia sal22" in the subject line of everyone of your messages?
To do a full rectified sine wave, just put an absolute value function on your waveform wire.

How to create a new variant and a job sheduled to use it for the ......

How to create a new variant and a job sheduled to use it for the exisisting programs

Hi
1. The ALV Grid Control is a tool with which you can output non-hierarchical lists in a
standardized format. The list data is displayed as a table on the screen.
The ALV Grid Control offers a range of interactive standard list functions that users need
frequently (find, sort, filter, calculate totals and subtotals, print, print preview, send list,
export list (in different formats), and so on. These functions are implemented in the
proxy object class. You as the programmer have the possibility to turn off functions not
needed. In most cases the implementations of the standard functions provided by the
control are sufficient. However, if required, you can adjust these implementations to
meet application-specific needs.
You can add self-defined functions to the toolbar, if necessary.
The ALV Grid Control allows users to adjust the layout of lists to meet their individual
requirements (for example, they can swap columns, hide columns, set filters for the
data to be displayed, calculate totals, and so on). The settings (list customizing) made
by a specific user are called a display variant. Display variants can be saved on a userspecific
or on a global basis. If such display variants exist for a list, they can be offered
to the user for selection. If a display variant is set as the default variant, the associated
list is always displayed based on the settings of this variant.
2. REUSE_ALV_LIST_DISPLAY
REUSE_ALV_GRID_DISPLAY
REUSE_ALV_FIELDCATALOG_MERGE
REUSE_ALV_COMMENTARY_WRITE
3. Use of Field Catalog is to determines the technical properties & add formating information of the column.
6. all the definition of internal table, structure, constants are declared in a type-pool called SLIS.
7.fieldcat-fieldname
fieldcat-ref_fieldname
fieldcat-tabname
fieldcat-seltext_m
5. Form user_command using r_ucomm like sy-ucomm rs_selfield type slis_selfield.
Sap provides a set of ALV (ABAP LIST VIEWER) function modules which can be put into use to embellish the output of a report. This set of ALV functions is used to enhance the readability and functionality of any report output. Cases arise in sap when the output of a report contains columns extending more than 255 characters in length.
In such cases, this set of ALV functions can help choose selected columns and arrange the different columns from a report output and also save different variants for report display. This is a very efficient tool for dynamically sorting and arranging the columns from a report output.
The report output can contain up to 90 columns in the display with the wide array of display options.
<b>The commonly used ALV functions used for this purpose are;</b>
1. REUSE_ALV_VARIANT_DEFAULT_GET
2. REUSE_ALV_VARIANT_F4
3. REUSE_ALV_VARIANT_EXISTENCE
4. REUSE_ALV_EVENTS_GET
5. REUSE_ALV_COMMENTARY_WRITE
6. REUSE_ALV_FIELDCATALOG_MERGE
7. REUSE_ALV_LIST_DISPLAY
8. REUSE_ALV_GRID_DISPLAY
9. REUSE_ALV_POPUP_TO_SELECT
Purpose of the above Functions are differ not all the functions are required in all the ALV Report.
But either no.7 or No.8 is there in the Program.
<b>
How you call this function in your report?</b>
After completion of all the data fetching from the database and append this data into an Internal Table. say I_ITAB.
Then use follwing function module.
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
EXPORTING
I_CALLBACK_PROGRAM = 'Prog.name'
I_STRUCTURE_NAME = 'I_ITAB'
I_DEFAULT = 'X'
I_SAVE = 'A'
TABLES
T_OUTTAB = I_ITAB.
IF SY-SUBRC <> 0.
WRITE: 'SY-SUBRC: ', SY-SUBRC .
ENDIF.
ENDFORM. " GET_FINAL_DATA
The object F_IT_ALV has a field, the activity ACTVT, which can
contain four permitted values: 01, 02, 03 and 70. Each of the
activities 01, 02 and 70 controls the availability of particular
functions (in the menu and the toolbar) of the ALV line item list:
a) 01: "Settings -> Display variant -> Save..."
b) 02: "Settings -> Display variant -> Current..." and
"Settings -> Display variant -> Current header rows "
c) 70: "Settings -> Display variant -> Administration..."
Activity 03 corresponds to the minimum authorization, which is the
most restricted one: The user can only select layouts which have
been configured already. In particular, all of the other functions
named above are inactive with activity 03.
Now if you want to permit a user to change the column selection and
the headers as well as to save the layout thus created, for example,
but if you do not want to permit the user to administrate the
layouts, you grant him or her the authorization for activities 01
and 02.

How to deactivate Filter and Job in Job scheduling?

Hi,
My scenario is:
XI will poll the file from 3rd party system and wil send to R/3 via IDOC adapter.
On every sunday , R/3 will be down for 3-4 hrs for maintenance purpose.
I need to create job scheduling in such a way that XI sould collect all the message coming on sunday during that period
of time and after endtime has reached , it should process those message and should send the message to R/3 system.
I have created Sender/Receiver ID ..also create Filter and a JOBID.
while creating Job ID i specified the following
1: Start Date    = 18.08.2009
2:Start Time     = 11.00.00
3:End Date      = 18.08.2009
4:End Time      = 15.00.00
5:Period          = 7
6:Period Unit   = D (Days)
Job should be scheduled at 11.00.00 and end at 15.00.00 ,filter and Job both should deactivate and after 15.00.00 it should process those messages.
But the problem is it doesnt deactivate the filter.
I tried using SXMS_JOB_DEACTIVATE and SXMS_START_JOB_AT_ONCE
Both deacitvtes the JOB but not filter.
Can any body tell me , how to go with it.
Also if I have to write a report, what all things are required.
regards,
Mayank

Hi Volker,
Down time for R/3 is more ..so i am not sure whether XI will trying till that time or not.
And XI is not able to than all the incoming messages in XI during that period of time will be Red Flag.
can we write a report in XI such a way that .. all the queued messages should be processed ..thorugh Job scheduling.

How to create a optional filter condition in Universe

Dear All
I am using BI 4.1 ( .Unv ) , we need to add a optional condition in Universe. I tried different ways to do it, but unable to do it correctly.
In one of my approach, I created a report and put a optional prompt there then edited the SQL and copied that prompt condition and pasted that into a Universe condition. Then I used this filter into a report when i ran the report without selecting any value into the prompt it was throwing an error.
Please suggest if there is any way by which we can do this.
BO should have this functionality for better end user experience.
Thanks,
Mayur

Hi Bill,
Yes we are still using .unv as the universe we have is created in 2008 and since then we been migrating this through different versions.
What I meant is a Filter which is created in the Universe and which has ability to act like a report level optional filter ..means if you select any value then it will fetch data for that selection else it will give data for all LOVs
Yes BO has optional prompt functionality only for report level filter .. I mean when you pull a dimension into filter panel and select its value equal to prompt and in prompt properties you check mark the Optional Prompt option.
The requirement is to create a Universe level filter which when used into a report then it should should have this optional prompt functionality. either users can run report with setting some value or without selecting anything.
Thanks

This query completes in a not acceptable response time of more than 2 minutes and this is why it has been handled to me for possible improvement.
As you might have already pointed it out from the above execution plan, the operation number 19 is the most time consuming operation (TABLE ACCESS FULL of T5). The query without the EXISTS part represents our data. This part of the query is very fast. It gives about 1500 rows. However, when we want to limit those 1500 records to only records satisfying the exists clause (10 records), the query starts not performing very well because of this full table scan on T5 (5,5 millions).
The ideal situation would have been to :
(a) first join table T5(alias veh) with the table T4(alias obs) using the join condition (predicate 17) limiting the number of record from T5 table
(b) and then filter from T5 table (predicate 19)
But in this case the CBO is starting by a costly full scan of the entire T5 table (5,5 millions of rows operation 19) before sending this enormous amount of data to the HASH JOIN operation 17 which finally throw away the majority of T5 rows not satisfying the join condition : access("OBSV"."VEH_ID"="VEH"."VEH_ID")
I have already verified that the table statistics and their join column statistics are up-to-date and are reflecting the reality. But failed to know how to let the CBO automatically doing what I want it to do i.e. Join first and then filter.
When I discussed with the client we agreed to re-factor a little bit this query so that it is now completing in few seconds.
The new plan is not using bloom filter and the veh table is accessed via its unique index on VEH_ID (18 - access("OBSV"."VEH_ID"="VEH"."VEH_ID")) before applying the filter operation. Exactly as I wanted it to be in the original query
Have you any idea on how to change this join method/order so that the full table scan is post poned? of course without refactoring the query
Do you think that bloom filter is the culprit here?
Thanks in advance

PS : and veh.ac_number between :ln_min_number and :ln_max_number
These two imput parameters are beyound the known low and high value. But even when I used min and max value taken from the table (min = low_value from stats and max = high value from stat), the plan didn't changed

Jonathan,
I got the plan I was looking for.
It is not exactly the same as the execution plan that corresponds to the re-factored query but it is what I wanted to have.

Spot how the predicate 17 and 18 are now in the position I wanted them to be i.e probe first the T5 unique index using the join condition and then filter the table T5
But, there is always a but, why am I obliged to hint?
Where did I got something wrong (statistics, optimizer parameter, etc...) so that the CBO did not opted for this execution plan without a hint?
Thanks

Bayer Filter and colour balance.

Hi all.
I have recently been acquiring images using a mikrotron MC1363 camera and LV code 'Grab and save to AVI'. I have then used ImageJ to create a stack of U8 images. My problem then arises in that I need to apply a bayer filter and colour balance to the images. I have been sent a correction matrix by mikrotron and extracted pixel intensities from the U8 images, but am now stuck. I don't know how to use the information accrued to give a debayered image of true colour. Any advice would be great.
Attached is:
Tthe MC1363 manual
The matrices supplied by mikrotron (lupa1300)
An image folder containing:
-A true colour image
-A snap taken using the MC1365 of the true colour image
-Images of the colours red, green, blue, white and black extracted from the bottom right hand image, as u8 jpegs.
Thanks.
Dan.

Hi Danbubbles,
The pixels of the Bayer filter are arranged in a checkerboard pattern on the sensor. There are twice as many green as red and blue pixels in order to mimic the higher sensitivity of the human eye towards green light.
Due to the filter each pixel measures only one color. The two remaining colors are estimated (interpolated) using the eight surrounding pixels. This technique is called Bayer demosaicing or Bayer to RGB Conversion.
http://www.stemmer-imaging.co.uk/en/glossary/5287-Bayer-Filter
As far as I'm concerned there exit different "de-bayering" algorithm, which are different in terms of quality and performance, but in general
0#
you "move" a structuring element - which is like a subset of your input-image - across your input-picture starting at row = 0 column = 0, which is indexing the same pixel in both of your input AND output-image: http://www.mathworks.de/help/images/morph6.gif
1#
then you calculate a new value for this particular pixel in your output-image via interpolating the indexed pixel and its adjacent pixels in the input-image, e.g. like described in this pdf:
http://www.matrix-vision.com/tl_files/mv11/Glossary/art_bayermosaic_en.pdf
2#
then you move on to the next pixel which should be at row 0, column 1
repeat, until you reach the pixel at row n, column m
