How do impedance analysis

What instrument or method can be applied to the analysis of impedance in a circuit?

If this tour has included some capacitors and inductors, the multimeter is not his answer, heihei.

I need get the resistance and reactance circuits in Multisim.

Hey, Fangel.

The best way I know to do what you want in Multisim is to run an AC analysis in simulation menu, under "analysis-->. Set up the bandwidth, and the number of points, etc., the way you want and run analysis AC. After that, run the "postprocessor" (also in the simulation menu) and have it draw or voltage complex to your node of interest from the list. As noted above, the voltage will be equal to the impedance when your test source is a 1a current source.

For example, if my node is v (1), I tell him graphic "frequency", "re (V (1))" and 'im (V (1))', which will produce a table of the complex impedances at all frequencies. See the image as an attachment.

The series resistance is the real part (re (V (1))) and the reactance is the imaginary part (im (V (1))).

Hope this helps,

How to export all the analyses with an export buton

Hello, I am interested how to export analysis different with one button export, at the moment I have 3 tests on 1 dashboard in OBIEE 11.0.1.9 and on all the analyses I export, button but I need all the analyses to be in 1 Excel file so I look for a solution summed up the export option, but I can't find. Any help is appreciated.

Hello

First, I checked your other threads and it's "11.1.1.9" and not "11.0.1.9" - just to be precise.

Secondly, what you are looking for is 'Export' option in the dashboard menu:

You can not only export all analyses on your page as you request but even all analyses on all pages of the whole dashboard.

iOS 10 bed - sleep analysis does not

I use the new feature in iOS 10. The first night, he showed me a graphic analysis of sleep. But every other night, the alarm sleep wake up properly but there is no data from the analysis of sleep. The days are just empty.

I did disable the feature or did something else to change the settings. It is simply not show me how long I slept.

It is a disappointment - I was really looking forward to this feature. Anyone else having this problem, or am I missing something?

I wonder also how works the time of sunset. How she not analysis sleep? With the right movement? Should it be on my bed, or can it be on my bedside table? How this compares to an application like sleep work? I use for several months now, and it looks even better that bed IOS. Sleep wake me according to my cycle light sleeper, or only at the time, I put?

Satellite C660 - some Web page icons do not work

First of all please forgive me for being very naïve about the functioning of the laptop. I know a little but nothing more than how to perform analyses of virus/malware and surf the net.

I have a laptop C660 - R15 (PSC0LE). I started to have problems with IE8 in windows 7 (it came with the laptop). I noticed that some Web page icons or menus will not work. At first I thought it was a problem of java so made sure that I was running the latest version. But it still persists. So I then upgraded to IE9 that Windows 7 has suggested. This is where the problem has increased.

I can not yet use icons on Web pages and also my laptop now works very very slow when I try to open folders/programs. Internet works ok (ish) but sometimes goes all too slow.

I upgraded my BIOS for a keyboard problem, I had (it had been delayed evil), which fixed the problem and I also ran program PC Health Advisor who said I need some driver updates.

Is it a Windows 7 problem? Or is there anything else I should look at?

Keep your answers in terms of base because I admit openly that I am strongly a technophob with regard to the functioning of the laptop.

It seems that my question has been moved, but it is still. Also the computer is trolling again and it is sometimes so bad that it takes more than 3 minutes to sort. Even when I Ctrl, alt & del it takes forever for the Task Manager start to appear. Any ideas?

Analyze a. PDM file

Hello, I am looking for an analysis about the .tdms file which is generated from my LabVIEW program. I have a program that generates a. TDMS file with thousands of data points that the things on the list, such as date/time, status of pine, County of encoder etc.. What I want to do is to write a .vi that analyzes data from the .tdms batch file (the .tdms file are produced every 15 minutes) and can make a min/max/average of a column of data. Finally, the file should be exported to Excel. I have the last covered part but how would an analysis about the .tdms file? What would you even use LabVIEW for this?

scanning multiple pages in pdf format

Printer: HP Officejet 4620

System: Windows XP

How to scan multiple pages into one PDF document?

Hey coolmanoh,

There is a document containing information on how to perform analysis with the Officejet 4620. The document explains how to scan multi-page documents into a single file. As sabretooth04 said, the HP scanning software should have a + box to add additional pages in the scanned document.

Please take a look at the document and let me know if it is able to achieve the desired result. The document can be found by clicking here.

Windows Essential slow full scan

Why the full scan takes 9 hours? Why when analysis indicates through the complete green line continues? It is impractiocal since I never leave my computer on more than 4 hours.

I would uninstall Security Essentials, reboot and then reinstall. See if that helps.

It depends on the size/number of files as to how long the analysis will take.

Filter the two columns with a variable

Hi guys!
I am new to Oracle BI EE and I following the task at hand.
In my database, I've followed columns:
ID | VALUE | VALID_FROM | VALID_TO
The first is the unique ID, the second value I need to show my analysis, the latter two are dates.
I need to prepare the analysis when user asks values at a time, so I'll have to show all lines where the date selected by the user is greater than VALID_FROM and smaller than VALID_TO (but the user must enter only once).
I am a complete beginner and have no idea how prepare this analysis? Could you give me some advice?
Best regards
Greg

I did not understand your exact need. A date value, will be user input.

For example: 01.08.2014, then your analysis will be filtered by;

01.08.2014 > VALID_FROM and

01.08.2014<>

If so, you can create a prompt for dashboard column and give set a presentation for this column. Then, you will use this presentation for valid_from and valid_to columns column.

Chapter of digitized book converted into word and then back to pdf - PDF final chops pages

Hello
I downloaded the trial version of Acrobat Pro DC because I was told that instead of having to take notes in the manual of chapters of books scanned in my referencing system, I could convert it to a readable/editable word document, then back to pdf format (which is easier to use in the likes of Mendeley, devoir2 etc.).
I managed to convert the original scan - which has two pages of the book by page, format the format landscape and landscape - in Word and all the text was maintained. This was very good. The problem occurred when I tried to convert this word in a PDF document. At this point, only the left side of each page (if the left page of the open book) was complete and the right side has been reduced by half. I tried to turn all of the text in the word so document flowing sideways through a portrait page layout (which is how the initial analysis was and I just turn it in my referral program). It's the same thing when I tried to convert to pdf format. The right side of each page was still cut off, even if the version of Word was all there.
Anyone has a suggestion how to get around this problem?
Thank you.

I think that you have shared it for 1 HR time. Looking at this analysis is not a problem. So more than half of your problem is solved here. Then you can check how the soft analysis.

Have you looked at thead: run to analyze the ratio is 49 no problem ?

Also, please check whats the % CPU Non-Parse ration? If his high, nearly 90 then the analysis is not a problem for you. Hope this helps

I have two sql scripts. Having just insert statements and the other using bulk insert both do the same thing.

Not really valid for the purposes of comparison.

The fundamental question is what makes in bulk for faster processing. It is a well-known and easily answered--reduction in context switches between SQL and PL/SQL engines. And that's all. Nothing more and nothing magical.

The easiest way to show this difference is to eliminate all other factors - especially I/O as a trial may be at a disadvantage by the physical i/o, while the comparison test can be promoted by e/s logic. Another factor that must be eliminated is extra unnecessary SQL that adds more overhead (such as the use of DOUBLE and unions) and so on.

Remember that it is critical for the reference driver to compare like with like and eliminate all other factors. As simplistic as maybe keep it. For example, something like the following:

SQL> create table foo_table( id number );

Table created.

SQL> exec :iterations := 10000;

Why an empty table? Eliminates potential problems with the physical versus logical I/O. Why a delete and not Insertstatement? The same reason.

The foregoing shows how slow hard analysis is clear. It has the advantage of soft analysis. It has the advantage of reducing the change of context, at the expense of additional memory - as bench 3 consumes much more memory (PGA) that other points of reference.

Also note that these marks the exact same delete SQL statements - using different approaches. Where the approach only (and not the SQL) made the difference. This means that we can draw valid conclusions on each of these approaches.

Can we say the same thing with the scripts you used to "show" that the treatment bulk is apparently slow?

Insert XML data base records

Hello

I have a requirement to write a stored procedure that will be an XML file as an input argument and the search for the tags < salary / >, < Manager / > in the XML file and insert those values in a table.

The pointers will be appreciated.

Concerning

Two options are to analyze this in PL/SQL and pass these results in INSERT statements or spending it all in an INSERT

SELECT... OF... article and let the DB do all the work for you. Without knowing more details, an example of how to do analysis in PL/SQL as an XMLType can be seen in the second method in {: identifier of the thread = 926354}. You would need another loop internal to analyze all OrderDetail nodes because they can repeat for each node in the client.

If the structure of the table that you ever go in allows it, you can use this as the SELECT part of your INSERT statement

SQL> SELECT customerid, orderid, productid
  2    FROM XMLTABLE('/ROOT/Customer'
  3                  PASSING XMLTYPE('

  8  
  9  
 10   
 11   
 12

 15  ')  -- this would just be a variable instead of hard-coded XML
 16                  COLUMNS
 17                  customerid   VARCHAR2(20)  PATH '@CustomerID',
 18                  orderdetails XMLTYPE       PATH 'Order/OrderDetail') ta,

Analyze the directory all traces
Hi guys,.

Just a quick question:

How it would analyse a directory of any trace on a database (10.1) on windows?

I want to have an overview of all the messages of ORA-xxxxx.

Thanks a bunch!
Hello

Why you want to do.

You meant the path stored in the bdump directory if that is the case, then you can search for ORA - in alert log itself. Some of the ORA-error in the alert log creates the trace files.
```
grep -i ORA- alert_.log
```
or like what you need is given by
```
grep -i ORA- *.trc
```

Find the appropriate block size?
Hi all

I think this might be a simple question, how to find the block size that is appropriate for the construction of a database for a specific application?

I had always seen default 8K block size is used everywhere (about 300-350 databases I've seen so far)... but why and how they believe this block size blindly before creating the production database.

Also in the way the parameters of memory are finalized before creating the database?

YasserRACDBA wrote:
OK I understand, but how will comparative analysis for the examination does not block size?

I mentioned BLINDLY word because before implementation into production, how s/n allows to find the block size that is appropriate for this application.

Well, as I said, it needs comparative analysis. And if you are not able to do it, the best is to stick to the default size. Read more intensive databases may need some play with the size of the block, but this summary is not authoritative at all, at least not from me. So I say to be on the safeside, by default would help you.
>
Right now I have no clear idea on the database of benchmarking, can you please help with this if you have done this by hand before it please...
```
Charles and Greg presented very good test cases showing that using 8k is the most optimal choice in most of the cases.
```
Once again my bad luck that I lost this post before having a look. Are there opportunities to find these test cases?
