• Analysis of capacity Vcops algorithms

  Hello

  I would like to ask if anyone knows what are the specific algorithms used by Vcops to implement the predictive ability. Are they simple algorithms based on regression analysis for example or something more advanced, such as combined neural networks, etc.?

  Thank you!

  Its much more than just linear regression - there are at least 8 algorithms that work and are in competition to interepret data:

• noise of biaxial precision accelerometer

  Hello

  I do calibration on accelerometer analog biaxial acceleration providing the angle of the sensor measurement.

  Based on spec sheet of the analog, the sensor should be in equation linear V = Ka + B

  V = output voltage

  K = linear sensitivity

  a = acceleration of axis

  B = polarization voltage.

  However, I turn the sensor with a known angle, I get the tension. Draw the graph of the voltage compared to acceleration, I'm not able to obtain a linear curve V = Ka + B, but not linear graph.

  How can I determine the non-linear error and the resolution on the graph newly traced in labview? I collected data. and I want to do a regression analysis. How can I do it in labview?

  After getting the non-linear regression, how will I know my new model (new equation) improved in error and resolution?

  Can anyone help ple

  your kindness is much appreciated

  OK, this description makes sense.  Probably nothing wrong with your Setup.  If you want to create an equation using data points you acquired during the tilt in the X direction and Y?  The function Arctan not serve the purpose?  Divide all values of all values of Ay Ax and feed the ATAN function table.  I used three-point line in the following example, and the output is linear.

  

• Problem with large XML files over HTTP segmented analysis

  I am trying to isolate a bug introduced when the JRE in Java 7u51 use 7u71 without changing the codes. The problem seems to be very similar to: Bug ID: JDK-8027359 XML parser returns incorrect results of analysis.

  Further investigation showed that it was also introduced in the same versions (7u71) where this patch has been applied. Unlike this bug, my XML is marked as version 1.0. He also seems to be with only large XML, the order of 10 MB files or more.

  Is the closest I've been able to reduce it down to the code uses JAXB to disrupt a flow which tells me that the debugger is an org.apache.http.com.EofSensorInputStream / org.apache.http.impl.io.ChunkedInputStream. The exception I get is not consistent, but usually appears from pieces are replaced or mixed, with result the letters appearing in the attributes that are actually numbers, or like the following, where an attribute "testAttribute" gets partially crushed by the end of a timestamp that was in another section of the XML file.

  javax.xml.bind.UnmarshalException
  - with linked exception:
  [javax.xml.stream.XMLStreamException: ParseError at [row,col]:[1,98748]

  A code here which seems to reproduce if you can connect to an XML server that returns a large segmented XML file:

    SchemeRegistry registry = new SchemeRegistry();
    registry.register(
                  new Scheme("http", 80, PlainSocketFactory.getSocketFactory()));
    HttpClient client = new DefaultHttpClient(new BasicClientConnectionManager(registry));
    String url = "http://someUrlReturningAlargeChunkedXML";
    HttpGet method = new HttpGet(url);
    HttpResponse response = client.execute(method);
  
    InputStream inputStream = response.getEntity().getContent();
  
    XMLStreamReader responseReader = factory.createXMLStreamReader(inputStream);
    JAXBElement<JaxBObjectOfResponse> wot = unmarshaller.unmarshal(responseReader, JaxBObjectOfResponse.class);
  
  
  

  There is no error if you connect using URL.openStream () to the same service. If I read bytes directly and write to a file, there is no error. The error occurs only when I try to disrupt it is great and I use Java 7u71 (or later). It can be constantly repeated with the jsp webapp I use, but did not show the error when I used the same code with a Wikipedia dump XML file.

  How can I unmarshal differently to avoid this problem? Or, how can I best isolate the bug so it can be sent to the appropriate bugs system?

  Seems to be related to this bug, which will be fixed in 7u80 and others (in April?).

  http://bugs.Java.com/bugdatabase/view_bug.do?bug_id=8059327

  Tests with the final version in early 7u80 showed it fixed my related question.

• Segmentation of a huge CSV file for easier analysis

  I have a CSV file that contains 3 columns: time, voltage and current.  This data covers a period of 12 days with 1 ms between the samples and the size of the file is 53.4 GB!

  I use LabVIEW to chunk this file into pieces easier to manage for analysis using spreadsheet File.vi reading and write a File.vi spreadsheet and my method works very well... to a point.  Here's a snippet of what I do:

  

  I use the "start offset reading" of entry to reading worksheet File.vi inch my way through the file, but since it is a type of data I32 it rolls more and VI out errors.  I think I have to do, is remove pieces of the main file that I read and write in their respective smaller file, but the method to do this is me stumping.  Y at - it suggestions on how I could pull this off while using the worksheet vi file (to avoid reinventing the wheel as much as possible)?

  Some ideas: I'm playing:

  1. of iteratively, delete data and reset to '0' marker in the file (reading data in order from the present to the future).

  2. start at the END of the file (i.e. read data from future to present) and iterative set the smaller size, eliminating the data blocks that I will.

  The simplest solution would probably be to modify the existing worksheet screws (or a copy you make of them) - you did, they use 32-bit values to track the location, but if you look inside the screw, you should see that the actual file functions use 64-bit values (the values of 32 bits in the functions are actually used for backward compatibility). I haven't looked closely, but my guess is that you can simply change this option to be 64 bit and that your code should then be able to go through the entire file.

• Regression / channel function

  Hello!

  I want to estimate a value of table 3D attached.

  For example: if I = 600 X and Y = Z then 0.2 = 1492, this example works well, but if I = 900 X and Y = 0.14 I estimate the value of Z.

  Is it possible with tiara functions to estimate the point Z, with a regression equation?

  

  Hello Ayane,

  The 'ChnD3InterpPoint' function calculates the value of Z for X / values Y. It is based on a triple structure. In your case you gives the matrix structure in a triplet structure (functions in ANALYSIS basic 3D).

• Divide a waveform into smaller Segments

  I have a wave form that I would like to make an analysis of power quality to.  There are several segments on a waveform that I would separate in order to perform the analysis on each segment individually.  Is there a way to do this?

  I've attached a picture to show the waveform.  I want to this segment in every area where there is a major change.

  Hey,.

  What you want to do is to copy the data into new channels for the analysis on.  You will use a for or while loop to scroll through the data and then, when you notice the max of a specific segment change value, you'll want to copy this section to a new channel.

  Call the Data.Root.ChannelGroups (4). ("Channel", DataTypeFloat64) Channels.Add

  Call DataBlCopy("[1]/Time",1,16,"[4]/Channel",1)

  In your loop, you can still use the ChnFind or the SEC to find the numeric value.

• Help accomplish upright Fluctuation analysis (DFA)

  Hello

  I am tryting to fulfill a DFA of time series chart.

  I have the EKG signal, where I got the RR intervals. For the DFA analysis, I have to do:

  Analysis of upright fluctuation method proved to be useful in revealing the magnitude of correlations at long range in time series. In short, the time series analysis (with samples N) is first built. Then, the integrated time series is divided into boxes of equal length, n. In each box of length n, a line of the least squares method is suited to data (representing the trend in this area). The ordinate of the straight line segments is denoted by o_n(k).

  Then we detrend the time series integrated, y (k), by subtracting the local trend, o_n(k), in each area. The fluctuation of root-mean-square of this time series integrated and reorganized is calculated by

  

  This calculation is repeated on all time scales (dimensions of the box) to characterize the relationship between f(n), fluctuating medium and the size of the box, n., f (n) increases with the size of the box. A linear relationship on a logarithmic field indicates the presence of straight (fractal) power scaling. In these conditions, fluctuations can be characterized by an exhibitor, the slope of log f (n) line to log n.

  As a first step, first of all, we calculate the signal integrated according to the formula

  

  Hi, DFA frustrated me for a long time. My question has repeat box Analytisis segment for each window of the series. Which means that if there are 300 beats then beat 4 interval is repaeted 75 times while the beat section 64 is repeated 4 times with RMS for each length of window being f (n).  See my solution below. MinN and MaxN is the minimum and maximum window lengths.

  It is able to reproduce the same result as Kubios for the DFA.

  Hope this is of some use.

  See you soon

  Kevin.

  

• btl_gather() segfault on the analysis of memory

  When you try to run the analysis of memory in order to find a memory leak using 2.1.0 NDK, I get a segmentation fault in btl_gather() when backtrace capture is activated.  Without a trace captures on I have the memory leak information, but has difficulty tracking the flight without any backtrace info.

  It is with the NDK 2.1.0 and a playbook on OS 2.1.0.1088 (also tried with OS 2.1.0.1314 with the same result)

• Existing network, analysis

  Hi Experts,

  It's a pretty open ended question. I need to analyse the existing infrastructure in a perspective of network I was wondering what would be the best approach to collect this information. It's a rather massive network / convoluted with documentation very less or dated. How to approach you if you were to walk in such a situation would be like this.

  Announcement

  Hello Adeel,

  Assuming that access is available for all network components of the infra and none are configured for snmp querying or already part of a network card/inventory application, I would like to generally like below,

  (1) build a network from base level diagram and build ward [using 'sh ip int bri', 'sh cdp nei', "sh ip arp", 'sh mac addr' etc.] and continue to do so until the diagram has only devices/ISP devices at the edge interfaces.

  2) add on values [details Int, speeds, bandwidth etc avg] on the links above the said scheme.

  -If the infrastructure is too big, you can do it in the segments [Campus1, Campus2, branch, etc.]

  I hope this helps.

  Kind regards

• 11g segment Advisor

  I recently activated Segment Advisor in my 11 GR 2 Exadata database (automated maintenance tasks have been disabled when we first went live).
  
  I have it running for 3.5 hours per night at the moment. Of course, it is not enough to complete the analysis of a data base of 22Tb in a single night, but my question is if it will continue where he was arrested the previous night or if she will try to start from the beginning.
  
  It is running about five times so far, but has only analyzed a tablespace. I think I'm being unusually impatient and it of just to take a moment to get through a tablespace, but worry that he will be stuck analyzing the same part of the database never without my intervention...

  Hello

  I have it running for 3.5 hours a night at the moment. Obviously, this is not enough to complete analysis of a 22Tb database in one night, but my question is whether it will continue where it was stopped the previous night or whether it will attempt to start again at the beginning.
