confidence interval - slope delta

• Confidence in the PSC - tc interval

  Hello

  We measure the temperature with thermocouples connected to a cFP-TC-125 module. I am interested in the accuracy of the measurement of this unit. Of course, I know the patterns in the manual, containing different measurement error curves for different measurement situations. For a specific room temperature and the thermocouple, there are two curves. It shows a so-called 'Max' and the other a measurement error "type." I understand the difference, but we want to use the information to calculate the total measurement error (which also contains the error of thermocouple sensor and different error from an average of measurement points). Well, I got to a point: If you add up different measurement error you must use the same interval of confidence, because it is the scale of the measurement error.

  The question is, if someone could tell me what confidence interval not 'Max' and 'Type' belong. What 1sigma, 2sigma, 3sigma? In a first approach, I would think that "Type" is 1sigma and 'Max' is 3sigma. But, assuming a normal distribution or a uniform, this does not seem to fit the data curves.

  Thanks for reading, cordially

  Hello

  I did some research and I can answer your question:

  Figures for the errors of different thermocouples use values for margin of error / error page 15 the same manual calculate typical (15-35 ° C) and maximum (40, 70 ° C).

  And I have confirmed that these maximum errors indicated in the manual are taken at the 99% confidence interval, script readings the worst.

  I hope that this answer to your question.

  Good day

• standard deviation for the slope of the linear fit

  I need away from the slope of the linear fit.

  Please confirm me if what I do is correct.

  I use the 'delta slope '' of the linear intervals did change the trust level of 0.95 to 0.68.

  But again, I'm not sure I can identify the slope delta as the deviation of the slope.

  Thank you

  Hello

  I did some research more.

  As I understand it, slope delta (or radius of trust) can also be referred to as margin for error.

  You may need to do more research on your own in this regard, but it seems that the two are different types of analysis. Standard deviation is a measure of the variability of a set of data, while the slope delta (or margin of error) refers to the amount of random sampling error. If you can get a direct link between the two, I'm not sure, however the first link below indicates that this is possible.

  I hope this gives some more.

  Regarding the algorithm we use in the interval linear form VI, I think that the following document would be a good start.  There is a section called "confidence interval and interval of forecasting."    It describes the algorithm we use.

  I hope this helps!

• IKE Dead Peer Detection between Cisco ASA and Cisco PIX

  I have a network environment in Star with about 30 offices of satellite remote using VPN Site to Site connectivity.  The majority of remote satellite offices have the features of Cisco PIX 501 running PIX Version 6.3.  The hub office runs a version 8.2 (1) Cisco ASA.

  I configured Dead Peer Detection on the Cisco ASA device at the office hub with the default settings of the following-

  Confidence interval - 10 seconds

  Retry interval - 2 seconds

  I think I'm right assuming that raises are limited to 3 before the tunnel is completely demolished.  Basically, the problem that I am facing is with several remote satellite offices.  What seems to be the case, the tunnel between the remote offices and the hub is demolished (probably because of the length of IKE, always 86400 seconds) and the tunnel then fails to renegotiate unless traffic is physically forced from the hub office.  The tunnel NOT to renegotiate after satellite office, ONLY the end of the hub; so that means sending traffic to the satellite when the VPN tunnel is out of service, not to renegotiate the tunnel.  The Hub office is a colo and therefore traffic rarely comes to that end, the tunnel remains so down until manual intervention occurs and the ICMP traffic is forced into the tunnel.

  Should the KeepAlive and retry interval settings corresponds to both ends, for example if the two devices be configured for DPD?

  What are the potential pitfalls to the extension of the life of IKE, and this will help or even hinder the problem?

  Thank you in advance for helping out with this.

  Hi Nicolas,.

  I think that the two DPD settings must match on both ends, if these do not match then problems like yours might arise which seems to happen here, is that one end shows a tunnel down, but the other end may not detect it down, we could have to watch debugs, or record two ends to see if this is the case , setting in the meantime ike DPD for same timers could hetlp on.

  In regard to the increase in the life expectancy of IKE, well you just need to be aware that this could allow keys to be discovered since these are not renegotiated unless the tunnel is down on the level of IKE. Other than that I don't see why this would affect you.

• Resize, then check that collide and repeat up to Max

  I have a trapeze, which is the box guide and works of art that must always be maxed out size so that she.  I wrote a script that moves the work low center then back up 3points so that it is not touch.  I need the script to browse looped and resize by 101% and then restore only the function of Center and check face again.  I do not know if there is a .collide or how to on this subject, but I went ahead and wrote the rest of the script.  The part which reads 'arttouchguide.collide' on line 07 is the part that I have problems with, and it's just a placeholder as I know that it doesn't work right now.  The code below is a .jpg file of what I am working with.

  #target illustrator
  
    var selecteditem = app.activeDocument.groupItems[0];
    
    
    
    for ( arttouchguide.collide = false)
    {
     selecteditem.resize(101,101);
     centerArt()
  }
  
  function centerArt()
     {   
         var thisdoc = app.activeDocument;  
          var selecteditem = app.activeDocument.groupItems[0];
          selecteditem.selected = true;
          var hasDocCoords = app.coordinateSystem == CoordinateSystem.ARTBOARDCOORDINATESYSTEM;
          
          
          var p = thisdoc.pageItems;  
          for (var i = 0, l = p.length; i < l; i++) {  
              var pID = p[i];  
              if (pID.guides == true) {  
                  var guideBox = pID  
              }  
          }   
          var wNum = guideBox.width;  
          var hNum = guideBox.height;
          var swNum = selecteditem.width;
          var shNum = selecteditem.height;
          
          var sxOffset = (swNum/2);
          var syOffset = (shNum);
          var xOffset = (wNum/2);
          var yOffset = (hNum-3);
          
          
          var xNum = guideBox.position[0]+xOffset;  
          var yNum = guideBox.position[1]-yOffset; 
          
          var guideXCenter = xNum-sxOffset;
          var guideYCenter = yNum+(syOffset);
          
          var sxNum = selecteditem.position[0]+sxOffset;
          var syNum = selecteditem.position[1]-syOffset;
          
          //to test your script for position un annotate the two alerts below
          
                // alert("GuideBox Data:\nWidth: "+wNum+"\nHeight: "+hNum+"\nX Position: "+xNum+"\nY Position: "+yNum); 
                // alert ("Selected object Data:\nWidth: "+swNum+"\nHeight: "+shNum+"\nX Position: "+sxNum+"\nY Position: "+syNum);
                 
                 
          //changes the position of the selected artwork to the center of the guide box.
          selecteditem.position = [guideXCenter, guideYCenter]    
          
      }//end centerart
  

  

  The red line is the guide, the part of lime is the work.  It will increase the size of the art, focus, move it to the top by 3 points and look for overlap/collide and repeat until it's moving.  It's the only way I can think up the work inside a trapeze.

  Here you can select the two objects before the race. Trapezoid must be isosceles, having only 4 pathpoints, it must be closed. Art to fit into the trapeze can be anything, as long ago an article, and it should be on top of trapeze.

• Critical value of students T - function

  With the help of the contributors to the Forum, I managed to create an Oracle table that reflects T student (T-Stat) used to calculate the confidence intervals. The function created with the help of the user from the forum works as well. The user to function between a sample and the confidence level and the function returns the critical value of t is below a subset of the table:

  The degrees of freedom table maximum is 500,000. Tables T can go to infinity, but we left the degrees of maximum freedom to 500,000, and I tried to change the function so that if the degrees of freedom is superior to 500 000 given a user specified confidence interval, the critical T Stat by default to a certain value. Compile, but when I try and enter a sample size greater than 500 001 which equals N-1 degrees of freedom or 500 001, then the function just returns Null. I think it has something to do with the fact that the degrees of freedom superior to 500,000 does not exist in the table and merges. I guess I need to use some sort of function NVL but did not understand how do. Here's the function:
  

  CREATE OR REPLACE FUNCTION critical_t_value
  (   in_sample_size     IN   NUMBER
  ,   in_confidence_lvl  IN   NUMBER
  )
  RETURN NUMBER
  IS
      return_val  NUMBER;
  BEGIN
      SELECT  case when in_sample_size > 500001   and in_confidence_lvl = 0.1     then 1.6450000000 
                    when  in_sample_size > 500001 and in_confidence_lvl = 0.05   then 1.9600000000
                    when  in_sample_size > 500001 and in_confidence_lvl = 0.01   then 2.5760000000
                     when  in_sample_size > 500001 and in_confidence_lvl = 0.001 then 3.2910000000
                      else critical_t_stat end
      INTO    return_val
      FROM    students_t_table
      WHERE   df  = in_sample_size - 1
      AND        confidence_lvl   = in_confidence_lvl;
   
      RETURN  return_val;
  END  critical_t_value;
  /

  The case statements with the default values do not once again I think it's probably because there is no df > 500 000. Any help would be appreciated. I use Oracle 10 g, by the way.
  
  Thank you

• First HP: Lack of Sections of first graph with steep slopes on HP

  I saw somewhere an old post on the Internet where a user was having difficulty to see the graph of y = x ^ 4 (x-2)(x-6) using a "Decimal point" display window and the "Evolutionary" method in the application of the function. The chart has not demonstrated the branch of the chart with the x origin of (6, 0). The response at the time was to use a different window or switch to advanced graphics application. I don't like either of these options, because much cheaper calculators have not this problem.

  With a little experimenting, I found that the calculator will be graphic curves where the absolute value of the slope (derivative) is less than about 375 * (Ymaximum - Yminimum) / (Xmaximim - Xminimum) where the minimum and maximum levels refer to the values specified in the configuration of the land. When the curve is steeper than this amount, the curve has holes and gaps until this value exceeds of approximately 1500 *(Ymaximum-Yminimum) / (Xmaximim - Xminimum). At this higher value, the curve is usually not in graphic form at all. These expressions are based on the study of graphs of the polynomial given above, y = 1 / x and y = e ^ x for different values of configuration of land.

  I realize with the option of touch screen on the first HP for the graphics window resizing, calculator, developers should be a little more sophisticated in how to get the calculator determine the graph. The current 'Adaptive' method is too risky for me to use unless I know a little on the chart. And the graphic progress is too slow. HP working on another option or is there maybe a setting on the computer I do not use its full potential?

  I've only used the calculator for a few days, but others who have used the calculator for many more are also puzzled. Thanks for any info. You can send our way.

  It is currently being considered. I can't say when / if there will be changes, however on the political basis of HP on 'future-looking '.

  However, graphical representation is one of those things that is "deceptively simple" because it seems to be pretty easy but is actually infinitely difficult. It has in fact been mathematically proven that you * don't * create an algorithm to be quite accurate for the same simple algebra. All graphics engines turn example is a very simple method that collapses quickly for something else then the case of some, it's well, a series of different behaviors for different types of problems in an attempt to account for different types of situations.

  The average general graphic has been done in the past was "moving pixel, evaluate and connect the dots." This works for simple things, but falls apart pretty quickly. Most of the calculators except the first on the market at the present time use some techniques of "smoothing" kind of hide the types of problems, this method can generate and generally work well for simple cases. While that hides things, the problem is he hiding things. :-) In more complicated cases, it actually makes things quite worse.

  In this simple case, most of the systems actually get the "right" result because they always assume that a big jump in values one line drawn to connect them. Result directly in other cases where it draws a vertical line to an asymtote that shouldn't be there. That's why things like Tan (x) go very often vertical asymtotes where there shouldn't be any. To try to avoid this, you need the code to make a special analysis in the case of start trying to filter false positives. It seems that in this case, it is bad filter and eliminate the line here.

  For another thing of pleasure, try the example simple "sin(e^x)" on all your systems. You will get some pretty crazy things and strange patterns here where there should not be any. The "speculative", the first will be closer, but only the grapher advanced with its graphics of interval it gets correct.

  So in short, yes - you put this to our attention. In long, graphic representation is in fact much more complicated then one might expect. :-)

  I wouldn't really call it a workaround solution. This is the expected behavior.

  Build and write like a table and your waveform will be saved correctly.

  If you are going to write a point at a time, all you have to do is to keep track of what you want to use when you build your unique point to t0 and wiring waveform.

  EDIT: Is the column name 'Untitled' bug your client at all? It would have upset me. You can fix it by set the attribute of waveform for "NI_ChannelName."

  Hello danielgomes, sync is not always the case on fixed intervals, but this depends in part on certain situations and actions of the user: https://wiki.mozilla.org/Firefox/Features/Instant_Sync

  Well, I noticed today when I'm on that instead of the normal Google and search engine newtab there is something which is called delta houses... I went to about: config to change the newtab google... and changed my homepage... But when I open firefox, it will still pop up and open the tab that ever I close... After a bet, so I decided to reset firefox... I did and it still does not... My friend suggested to uninstall firefox. So I did... Lost all my favorites... Had to put em on and other things... Well, I've been well that as long as he got rid of the delta homes... Well, I was watching a video and closed browser it self... I opened it upward and houses delta was back. So any ideas how to get rid of >?

  Sometimes a problem with Firefox can be a result of malware installed on your computer, you may not be aware of.

  You can try these free programs to search for malicious software that work with your existing anti-virus software:

  • Microsoft safety scanner
  • MalwareBytes' Anti-Malware
  • TDSSKiller - AntiRootkit utility
  • Hitman Pro
  • ESET Online Scanner

  Microsoft Security Essentials is a good permanent antivirus for Windows 7/Vista/XP, if you do not already have one.

  More information can be found in the article troubleshooting Firefox problems caused by malware .

• How to remove extensions.delta from about: config?

  Hi there, my computer recently virus research Delta. I deleted all Delta programs on my computer and reset my internet options so that everything works fine now. I also have Webroot SecureAnywhere installed on my computer and a recent analysis said that I had no threats. However, when I go on the subject: config page, there are still several extensions.delta entries. I tried right click and hit reset, then by restarting Firefox and it didn't work. I also tried to delete in the prefs.js file and it did not work either. How can I get rid of these entries? Thank you!

  These preferences are to control the behavior of scrolling with the mouse and have nothing to see with the delta-search or other malware, so leave them alone.

  You should be careful whit change prefs and make sure you understand what is their purpose.
  
  When in doubt leave them alone and ask for advice.

• It is safe to remove all the "extensions.delta...". "user_pref file, how?

  After having suffered from the dreaded "research of Delta", I managed to get rid of most of the Delta. I managed to get my nails of the thumb on the new page, but every time I close and re-open Firefox, new pages come in white, and I have to reset.
  It seems that I have 23 Delta extensions, always playing on topic: config and also in Firefox Prefs file.
  Presumably it is these files that prevent re-opening Firefox if I put earlier.
  How to remove these 23 files without upsetting anything else?
