• How to achieve 360 degree display using arctangent of structure of the case?

  I have the sine and cosine signals. The tangent and arctangent are used to get the - 90 to 90 degrees. To achieve the 360 degree screen, I will use the absolute value and an additional degree, such as 90 180 and 270. I created the case and select parts, but I don't know how to link these two.

• Qosmio F50 - 10Z revolves around 80oc degress

  Hi guys,.

  Have a very little bit of trouble with my Qosmio F50 - 10Z, the GPU (9600M GT) revolves around 80 ^ o ^ c degrees when using, the system has been cleaned with air compress and is in perfect condition of the art, I use the laptop on a table computer as well to ensure air flow.

  Thank you very much.

  AFAIK Qosmio F50 is old enough laptop model and if you use every day on base maybe is time for cleaning professionals. Compress the air is OK but more of dust is just inside and cold air and cooling rack may be blocked by dust.

  I've seen repeatedly disassembled portable and it is raise what it looks like inside after two or three years of use. In my old notebook I found cat s hair.

  What is with cooling fan? It runs at maximum speed?

• Twist - Two monitors-> no metro

  I got this job once, but it no longer works and I'm all out of ideas.

  When I'm at my desk, I connect my Twist to two 24 "1920 x 1200 monitors. I open the screen 180 degrees and use the integrated keyboard and an external mouse. One of the reasons why I bought the twist is that she has two digital video ports (as opposed to a digital and a fuzzy VGA). I bought two cables Monoprice cheap (mini-displayport to displayport-full) and mini-hdmi to hdmi-full.

  The first time I put under tension, both monitors configured correctly for the extended desktop. But the metro has not begun. When I moved the mouse to the lower left corner, the starting rectangle does not appear. When I type Win - C, charms bar did not appear. Other than that, the machine worked fine. It was just like Windows 7 except without a start button.

  Then I installed the classic Start Menu and got the Start button. Classic Start menu is able to start Metro applications. When I tried to do this, for example with the games app, an error message appeared in a strip in the middle of the screen saying "this application cannot open. The screen resolution is too low for the games to run. "The screen resolution you change."

  Then after installing several updates from Lenovo, Microsoft and Intel (for the HD 4000 driver), Metro as magically started working.

  But I have unplugged, Metro stop, rebooted, and now no longer appears.

  I think that what happens is that Metro think the screen resolution is set to 0 x 0 pixels pixels because the built-in display is disabled. Earlier, when I got to work, I have somehow forced Metro use the resolution of 1920 x 1200 of one of the external monitors. I tried to replicate what I did, but I couldn't.

  I tried to change monitors via the usual methods: display-> graphics-> Output To screen, resolution and F7 project to a connected screen.

  I also tried to change the display in the bios (built-in, hdmi, displayport) start.

  I also tried to use Win-PageUp and PageDown-Win to change the metro starts on.

  I have the latest updates from Lenovo, Microsoft and Intel.

  Classic Start menu has nothing to do with this problem. The problem that happened before I installed it, happened after I installed it and still occurs after that I uninstalled it.

  If I run an external monitor the integrated screen, work of subway and opens on each screen function which is main (defined with Win-PageUp or in the display resolution). Metro stations works when the two external monitors are running.

  I tried every combination I can think but can't go back to where I was.

  Any ideas?

  I don't know who made the change (Microsoft, Lenovo, Intel, or anyone else), but this problem has been fixed.

• Precision in the reading of temperature PT100 and Module of NI9219

  Hello

  I m the temperature reading with a PT100, connected to the NI9219 Module. I put LabVIEW on mode 4 son RTD (PT100 range). I m able to read the weather temperature but I m do not know the right precision s or not. The temperature is between 25.5 and 25.8 ° C. Is this possible? I am able to do something to have more precision?

  Thank you in advance,

  Claudia

  Hi Claudia,.

  The specifications for the 9217 provide the absolute measurement accuracy Pt 100 RTD (3 and 4 sons) on page 14, it is not necessary to calculate [1].

  Since the 9219 is more flexible in the types of measures that it can bring, absolute accuracy for each use case is not provided. Instead, OR gives error of gain values and offset to be used for the calculation of the absolute accuracy [2].

  Follow this logic to calculate the absolute accuracy:

  (Absolute accuracy) = (entry reading) * (Gain error + drift in temperature) + (Offset + drift in temperature error)

  Reading the line "RTD 4-wire or 3 wire Pt 100" in the table on page 24, the error of gain and offset for a module between 20 and 30 degrees Celsius is ±0, 1% of reading entry for gain and offset sectors ±2400ppm. Drift in temperature comes into play when the module is outside the normal operating temperature, but for Pt 100, gain drift is ±15ppm and the offset of the drift is the ±60ppm (see page 25).

  So, for a module at room temperature 23 degrees Celsius and a Pt100 to 100 degrees Celsius using the 505 Ohm input range, the calculation is:

  At 100 ° C, the RTD would measure 138.5 Ohms if its temperature coefficient 0,00385 Ohm/Ohm / ° C, then

  Absolute accuracy = (138.5 ohms * 0,1%) + (2400 ppm * 505 Ohm)
  = 1.212 Ohm + 0,1385 ohm
  = 1.3505 ohms

  fracture of 0,385 Ohm / ° C, and

  Absolute accuracy = ±3, 5 degrees Celsius

• HP PAVILION P7-1155: p7-1155 graphics card with hdmi

  I need to replace the graphics card for my machine to my hd tv hdmi output. I received a link to a forum that took me to newegg expert. There, I was overwhelmed for choice. I looked at a few of these, as well as comments. PNY cards seem to have a good rep, but I'm not sure. I want one that gives result excellent for my panasonic plasma and also has a conn vga for an old pc that I use occasionally, as well as a DVI to my primary monitor (ACER LED). I want also to capacity dual monitor.

  I'm not in the game, but I want good graphics. Low power is necessary also for that area (P7-1155). I think that this box is 250 watts. I'm confused about the amount of memory it must have (1 g, 2 g). If I could get a couple of good choices for graphics cards, I'd be happy. Looking at all the choices gave me a headache. I am running windows 7 Home Edition.

  Maybe there's an ideal choice among them all, but that is deceiving me. Anyone with a few entries on it even better every obvious choice or stupidity would be useful.  I'm going through my dvr then go out on television.

  I don't want to make a mistake here, so I need expert advice. I would prefer a free fan, since many of the comments talk about fan noise. I like to keep the cost less than a hundred, but I don't want no exaggeration either.

  I would like to deal with NCIX.ca because I'm here because of their return policy and the Canada.

  Newegg here at the Canada gets things to the United States when it is not supplied to the Canada and it can take forever.

  I also found that the NCIX is easier to deal with when returns _ Newegg is too automatic for my taste.

  When it happens to a good card walked like this, 20 dollars or down doesn't bother me, but that's me.

  I'd rather pay more and get the best service.

  And this is an awesome card, I do a GT760 and pushing a frame interpolation program.

  http://www.dmitrirender.ru/

  It was the limitation of the 760 at 80 degrees (metric) and using about 86% resources maps.

  With the same program that GTX980 fans don't even come on, it works at 60 degrees and uses only 62% of the resource cards.

• Serial number is no longer valid

  Hello there (who may be reading this)

• Setting of Photomerge

  Data: a group of twelve images medium format (scanned film) who took birth by myself, standing on a Mountain Summit and the rotation in 30 degree increments, maintain the level of the camera and all keeping the same percentage of visible sky above mountains in the distance (the subject of the photographs).  My goal is to compose (stitch) these images with an absolute minimum of bending and distortion.  Because the elevation of the horizon changes for each of the twelve exhibitions photographs cannot be sewn to form a rectangular image bar.  It's OK because my priority is the fidelity of the way in which the capture of photos the distant beach of the summits and the elevation of the land from which the peaks of the changes in place on the 360 degrees of the horizon.   Given that, does anyone have experience with the parameters of the utility "photomerge" that would sting the twelve images with the minimum of stretching and distortion?

  Of course, I did a lot of really wide panos, including some 360 degrees.  Use the "cylindrical" for landscapes choice and check the box [] Blend Images .  You probably won't notice any distortion unless you are just next to a straight road or a wall.

  You say that your pictures are scanned from film...  Y at - it vignetting in them?  If so, you might find that you need to address shortly before the seams.  With all digital conversions Photoshop little known (via the lens profiles, etc.) how much correction to make.

  Furthermore, there is a common problem with Photomerge in Photoshop 20141 CC (which did not exist in 2014.0).  You use the 2014.1 version?  If so, do you have installed 14.2.1?  You can use that one instead.

• No program screenshot in CC?

  I realize that there are a ton of programs out there with varrying degrees of usefulness for this sort of thing. But I expect such a complete tools range as the creative cloud would have a way to record my desktop/other adobe programs. I work in marketing for a software company, if the vast majority of the video made by us, is the software itself. I hate having to rely on 3rd party and freeware programs video converters to do this. I understand that captivate has this ability... but for some reason, is not included in the package. I understand also there was a post of ideas, where this subject has been voted. However, I have not needed to access this page permanent.

  If anyone is aware of a change, or could point me in a direction where my pleas will be more usefulI, that would be appreciated. I guess I should also mention the reason why I want adobe CC to support the screenshot natively is because I love the whole CC to death! adobe developers, could run circles around these compettitors (techsmith for example) in my opinion.

• calculate statistical performance problems

  Hi all
  
  We run statistical calculation on a table that is completely deleted daily, filled and then analyzed. However, the statistical component of calculation takes more and more time each day. The table retains a kind of diary/history of statistics that were calculated before the deleted data? Or is there a reason why statistical calculation on about the same amount of data every day should take longer and longer time? We took 10g.
  
  A few notes:
  I can't truncate table because I need to restore in case of problems. I could drop and recreate once if it helps.
  Before deleting and filling, I disable all indexes, and then re-create them.
  Transfer us about 10 million rows every day in this table.
  A year of the entire process (fill + analyze) has taken 3 hours, now it takes 18 hours.
  We also got this error on the table: ORA-01555: snapshot too old: rollback segment number with the name ° ORA-02063 too small: before the T_SRC line
  
  
  This is the script in the procedure:
  

      execute immediate 'alter index IND_TAB1 unusable';
  
      delete from TAB1;
  
      insert /*+ APPEND */ into TAB1
      select
        COL1
       ,COL2
        from V_SRC1
       where change_date   between sysdate-1 and sysdate
          or creation_date between sysdate-1 and sysdate;
  
      execute immediate 'alter index IND_TAB1  rebuild';
  
      execute immediate 'analyze table TAB1 compute statistics';

  V_SRC1 estimated T_SRC table on the remote system.
  
  Thank you for the ideas.

  Hello

  When you insert and remove a large amount of data in a table, it breaks and he could accumulate a significant amount of unused disk space. When you perform a full table scan, Oracle scans the segment of the upper limit (HWM) that points to the location of the block used above, i.e. it scans all empty blocks as well. In order to reset the HWM, you can issue ALTER TABLE MOVE. Despite what the name suggest command, your table will not be moved anywhere, it will simply rebuild and recover any unused free space. If there are all the indexes defined on the table, they would have to rebuild after that as well (ALTER INDEX REBUILD of ).

  Alternatively, you may consider partitioning by date range (if your license allows it). With partitioning everything would become much simpler:

  (1) you load your data into the table and everything check
  (2) if it is ok, you just drop the previous partition; Otherwise, restore.

  With regard to the CALCULATION - it goes through all the data to calculate statistics, instead of using a small sample (in general, a few percentage points). It is slower than the ESTIMATE, and in most cases does not provide any advantage over it.

  DBMS_STATS ANALYZE vs - using ANALYZE for the collection of statistics concerning is now obsolete and not recommended. DBMS_STATS offers the same features, and much more, given that your version is 10g you should use DBMS_STATS and not to ANALYZE.

• Is the function of "fill light" on LR4?

  Hello

  I downloaded LR4 yesterday and I love it! I was watching a good tutorial by Serge Ramelli using LR3 in his tutorial and he uses 'fill light' a lot, but I can't seem to be able to find this feature in the LR4. Can anyone help?

  Have your task of darkening of the red dots on white background - you tried to do this by means of global adjustment? Maybe that is part of the change in the general tone, or more focused on the reds.

  For example, click the Panel of LGV (just below the tone curve to develop), and luminance, made the Red slider to the left-, picking up the adjustment tool targeted and or use. I use this kind of technique a lot and feel that it tends to maintain whole-image 'integrity' to a greater degree when using powerful local adjustments - but those who have too much place.

  So, if you wanted all red in the image for systematically more dark, HSL is a good way to do it. If you wanted that to happen in only a few places, a local adjustment will be needed instead, or -, but if this can (for example) works on contrastiness or tone of the shadow of these parts of the image, it should always be possible to brush just that carry on more or less; without the need to isolate the details of pixel of the stitches themselves.

  Rather than saying "the Red points are too light; It may be easier to repeat this as: "the difference between red and white must be exaggerated." Often to reformulate the problem, made a better apparent solution.

• At the same time index rebuild...

  OK, so I have a question that has puzzled me a bit. I think I understand the theory, but I am not convinced, so looking for 3xp3rt thoughts.
  
  I have the following table with the indexes following:
  
  Departments of instance name table Name Index
  AWESOME_DETAIL 20 1 AWESOME_DETAIL_B8
  
  The table itself has a DEGREE of 2 BODIES 1 value.
  
  What is happening is when the following is executed:
  
  ALTER INDEX REBUILD AWESOME_DETAIL_B8.
  
  the table is read in series, despite the index with a DOP of 20. However, when we do the following:
  
  ALTER INDEX REBUILD PARALLEL OF 20 AWESOME_DETAIL_B8
  
  The table is read with the parallelism and the treatment is faster (no surprise on the second part).
  
  When the index is rebuilt with the first statement, the degree of parallel remained unchanged at 20. If we run the second statement, and the index have had a degree of parallelism of the 2, then I expect the degree of parallelism of the index itself will be replaced by 20 (because I've seen this before).
  
  Is this expected behavior? Is the first statement saying Oracle "Hey, this rebuild operation does not have parallel" and the second statement saying: 'Hey, I'm specifying options of storage here, my friend, do in parallel of 20'.
  
  Essentially, the first statement is a pure DDL operation and the second statement is a DDL operation with storage options, where the change? And DDL operations ignore the declaration of principles on the subject, unlike, for example, a SELECT statement.
  
  I tried with a DISPLACEMENT of ALTER TABLE and saw the same behavior: without specifying PARALLEL in my statement, it read the table in series. When I specified PARALLEL, it read the table in parallel.
  
  Mark

  When you specify PARALLEL creating / REBUILD / MOVE, the degree is used for the C/R/M. it is always "in place" for all the readings (and will be used in DML If ALTER SESSION ACTIVATE PARALLEL_DML has been paid).
  However, the degree of PARALLEL set of the GET on the table / index is not automatically reused for the next RECONSTRUCTION/MOVE (although the degree that has been set remains!)

  Is the first statement saying Oracle "Hey, this rebuild operation does not have parallel" and the second statement saying: 'Hey, I'm specifying options of storage here, my friend, do in parallel of 20'.

  Yes, precisely.

  Greg,

  You are right. PSD is a Photoshop option.

  I export still frames as TIFF, open them in ch to change, if necessary, then Save_As PSD in Photoshop. Those import beautifully (I can even add layers and import everything as a sequence, if I need to) and work well.

  For others still Images (not yet export Frame), also check your pixel x dimension in pixels, too large photos can stifle a project, or the computer.

  Also, take a look at this ARTICLE on the BSOD (Blue Screen of Death), because there might be some useful tips out there, even if you do not get a BSOD, or restart the system.

  Good luck
