• Psychrometric charts using in Labview to calculate moisture?

  I built a hygrometer to mirror cooled for a school project and all control through labview. I'll have the dew point and the temperature of the dry dry bulb that I need to calculate the rate of moisture through an algorithm or a look up table psychrometric charts. can anyone help please.

  The necessary equations to calculate the relative humidity of pressure and dry and wet bulb temperature can be found here:
  http://www.SRH.NOAA.gov/ELP/wxcalc/formulas/rhTdFromWetBulb.html
  With both temperatures and pressure to come as long as variables, I would break just calculating what they have on the Web page linked, by first calculating the pressure of saturated steam and wet bulb ==> and then calculate the actual vapour pressure ==> then the relative humidity. All operators you need for these calculations must be under the function of mathematical operators range. You could call all individual operations, including the exponentials, or just use a few knots of formula.
  Of course, just dump everything in a while loop (with a delay), to make the system constantly monitor and update the moisture.

• Help with real pressure for BMP180 algorithm

  The algorithm provided by the BMP180 data sheet contains some features that ME8 can't stand not (Math.pow (), unsigned long, etc.). I tried the best I can reproduce it, is that correct?

  My code:

          long B6 = B5 - 4000;
          long X1 = (B2 * (B6 * B6 / (1L << 12) )) / (1L<<11);
          long X2 = AC2 * B6 / (1L<<11);
          long X3 = X1+X2;
          long B3 = (((AC1 * 4 + X3)<<OSS)+2)/4;
          X1 = AC3 * B6 / (1L<<13);
          X2 = (B1 * (B6 * B6 * (1L<<12)))/(1L<<16);
          X3 = ((X1 + X2)+2)/4;
          long B4 = AC4 * Math.abs(X3+32768) / (1L << 15);
          long B7 = Math.abs(UP-B3) * (50000 >> OSS);
         
          long p;
          if(B7<0x80000000) {
              p = (B7*2) / B4;
          }
          else {
              p = (B7/B4) * 2;
          }
         
          X1 = (p/(1L << 8)) * (p/(1L << 8));
          X1 = (X1 * 3038)/(1L << 16);
          X2 = (-7357 * p)/(1L << 16);
         
          p = p + (X1 + X2 + 3791) / (1L << 4);
  

  I don't seem to be able to display an image, but the Bosch code is in the BMP180 data sheet page 15, under the heading "Calculate real pressure"

  Hi Luke,.

  Well, your calculation code must be correct, so I think that the problem is with this line:

  UP = (data [0]<16 +=""><8 +="" data[2])="">>(8-OSS);)

  try instead:

  UP = (((data [0] < 16)="" &="" 0xff0000)="" +="" ((data[1]=""> < 8)="" &="" 0xff00)="" +="" (data[2]="" &="" 0xff))=""> > (8-oss);))

  Reason: your MSB is negative, to hide the added bits when byte gets promoted to int.

  To see why, play with this:

  class {shift

  Public Shared Sub main (String [] args) {}

  n bytes = Byte.valueOf(args[0]);

  System.out.println (n);

  System.out.println (n<>

  System.out.println ((n<>

  }

  }

  $ java - cp. SHIFT 1

  1

  65536

  65536

  $ java - cp. Shift - 89

  -89

• Perfect calculation App of the week (any activity) is incorrect

  I focused on using three ring activity App from Apple daily. Since 17 October, I haven't missed a day that would amount to 31 weeks to get my circles. A screenshot of the application indicate, however, that I did this 57 weeks in a row. So, I bought the watch September 24, 2015 (according to the fitness App in shape since it is the first day of the rings), which is only 35 weeks. I don't really have an answer, but Apple might want to check how it is calculated. Greg

• bi weekly loan using the HP 10bII calculator payments +.

  Hello

  Can someone explain to me please how to calculate bi weekly loan using the HP 10bII calculator payments +.

  Here is an example from real life:

  5.49% annual interest rate,

  loan of $35420,33,

  6 years,

  the payment should be $266,74,

  but I don't know how to do this.

  Thanks for your help.

  Andrew

  Hello

  Weekly payments = 26 paid annually.

  26 the value paid per year:

  26 OrangeShift P/YR (on PMT key)

  Now enter data & colon;

  5.49 press I / YR

  -PV-press 35420.33

  26 * 6 = press N (26 payments per year * 6 years, the result, 156 will be stored n)

  0 press FV (just to be sure that FV is set to 0)

  Now press on PMT and it will show 266,74

  Don't forget P/YR will remain at 26 until you enter a new value or reset the calculator (clear all does not reset it, but will remind you the current value).

• BMP180 in configurations multi master i2c uses I2CCombinedMessage for get-temp-and-pressure operations

  I noticed that, thanks to the I2CCombinedMessage it is possible to support the multi-master configurations, as a combined message is treated as a transaction, a single bus, where a rather lengthy communication with a slave i2c (as request of get-temp - pressure and designed by BOSCH for the BMP180 complex) is protected from interference by other masters of the bus. Great!

  But looking at fact sheet BMP180 of BOSCH, it turns out the I2CCombinedMessage is not a suitable driver for this particular problem, because the appliance rather lenthy delay between the command and reading - and the JavaDocs of the I2CCombinedMessage does not help on adding breaks in the recorded transaction.

  Therefore, it would be great if I2CCombinedMessage would have a .pause(long milliseconds) method.

  Is there something like that planned for a future release, or I have to go with the methods begin() and end() distinct (which is of course a workaround)?

  Hi Marcus!

  No,. pause() isn't in the plan for the near future. And Yes, begin () /end () workaround

• Weekly, fortnightly / monthly box calculation

  Hi people,

  I am designing a form and the customer asked for some calculations of output according to what a "weekly", "Fortnight" or "Monthly" checkbox is checked.

  I tried looking for the answer, but am completely confused.

  There are 3 areas on the form where this charge weekly or fortnightly/monthly calculation is necessary:

  Area 1.

  

  In the light of the foregoing, a box should be checked and the hours Minimum and the hourly rate is entered. It will then calculate annual income.

  The box should apply to these modifiers of multiplication: x 52 weekly, biweekly 26 x and x 12 monthly

  So, if someone has done 20 hours a week at the hourly rate of $15, the calculation of annual income would be: 52 x 20 x 15 = $15 600

  Area 2.

  

  In the light of the foregoing, a value of $ for the caregiver is entered, and then a checked checkbox. This will then provide a calculation of annual income.

  The box should apply to these modifiers of multiplication: x 52 weekly, biweekly 26 x and x 12 monthly

  So if anyone has had the help of the family $ 650 on a weekly basis, the calculation would be: $650 x 52 = $33 800

  Area 3.

  

  In the light of the foregoing, a value of $ for rental income is entered, and then a checked checkbox. This will then give you the calculation of annual rental income.

  The box should apply to these modifiers of multiplication: x 52 weekly, bimonthly x 26 x 12 monthly and each year x 1

  So if anyone had rental income from $500 on a fortnightly basis, the calculation would be: $26,500 x = $13 000.

  If someone would be kind enough to help out, that would be much appreciated

  Thank you

  All the boxes have a value to export (under Properties - Options). Set the values that you want to use in your calculations as the value of exports of these boxes (so, for the '52' weekly, fortnightly '26', and each '1' year) and then you will be able to use them directly in the first option on the calculation of your text fields tab: value is (product) of... Then select the fields in the list.

• Perform calculations between the weeks and categories

  Given this example, if I calculate the difference between each week the intention and filing to show in the lines of the plan again and again filing?

  Row#     SEM     STUDENT_LEVEL     COLLEGE     PROGRAM     STATUS     Y3W2     Y3W3     Y3W4     Y3W5     Y3W6
  
  1     40     GR     BN     BMA-SJ     14.Intend     132     132     137     139     139
  2     40     GR     BN     BMA-SJ     17.Deposit     100     111     115     114     117
  3     40     GR     BN     BMA-SJ     20.New Intend     0     0     0     0     0
  4     40     GR     BN     BMA-SJ     21.New Deposit     0     0     0     0     0

  For example, the value displayed in Col: Y3W3 line #4 deposit must be the result of line Y3W3 2 - Row 2 Y3W2. Digitally: 111 minus 100 = 11.
  Tier 4 after that calculation should look like:

  4     40     GR     BN     BMA-SJ     21.New Deposit     1     11     4     0     3

  If the change is negative, then we would show 0.
  
  There are also some Calc percentage within the week and the categories and between weeks and years, but if understand us this, we can hope that use to others, so we won't post the part yet.

  Hello

  You can get the difference from one week to the next (or 0) using the analytical LAG function, like this:

  GREATEST ( tot - LAG (tot) OVER ( PARTITION BY  status  -- and maybe other columns, like sem, student_level, ..., too
                                         ORDER BY      year
                        ,          weekno
                      )
         , 0
         )     AS dif
  

  Corresponds to the data you posted really what is in your tables, or is it the result of an earlier stage?

  If it's really in your tables, and then instead of select of your tables, select in a UNION of
  (a) your table except the lines where status = '21.New' file
  (b) your table, once again, with status ='21.New deposit "and the numbers of dif (as shown above) in the column tot.

  If the data you posted is a partially digested form of your RAW files, then dif can probably be incorporated into the digestion process.

  In any case, calculate dif until you rotate the data.

• Calculated for absent complex the day of the week

  I need to find the number of days absent per employee according to the following criteria. I'll explain using test table as below.

  the table below contains the data for each employee per day in the pt_hrs column, if the hours = 0 means that it is not present for that particular day. Friday is a weekend for us.

  case 1,

  Normal case since it is present every day except Friday, there are no missing for him.

  Case 2,

  If the employee is absent from Thursday and he reported to duty Saturday, then Friday is considered to be absent.

  Case 3,

  If the employee comes back from vacation let tell it the spokesperson of service directly on Saturday, and then Friday is considered to be absent.

  Case 4

  If the employee is absent from Thursday and he reported to duty Sunday, then Friday is considered to be absent.

  ,,,

  Thanks for posting of sample data, but always use 2 arguments when calling TO_DATE.  The TO_DATE call with 1 single argument has all the problems of an implicit conversion.

  Thus, a person is considered on Friday that if he was absent the day before or the day after, isn't it?

  Here's a way to do it:

  WITH got_absent AS

  (

  SELECT pt_emp_code

  pt_date - necessary only for date filtering

  CASE

  WHEN pt_hrs > 0

  THEN 0

  WHEN TO_CHAR (pt_date

  , "DY".

  'NLS_DATE_LANGUAGE = ENGLISH'

  ) <> 'FRI'

  THEN 1

  HOW much MONEY (SIGN (pt_hrs)) OVER (PARTITION BY pt_emp_code

  ORDER BY pt_date

  BETWEEN 1 PRECEDING

  AND 1 SUITE

  )<>

  THEN 1

  0 OTHERWISE

  END as absent

  OF pt_attendance_reg

  -WHERE... - most filtering can go here

  )

  SELECT pt_emp_code

  SUM (absent) AS no_of_days_absent

  OF got_absent

  WHERE the absent > 0

  - AND pt_date > = TRUNC (SYSDATE, 'MONTH') - Date of filtering goes here

  GROUP BY pt_emp_code

  ORDER BY pt_emp_code

  ;

  Output:

  PT_EMP_CODE NO_OF_DAYS_ABSENT

  ------------ -----------------

  R002                         2

  R003                         4

  R004                         3

  This assumes that there is exactly 1 row for each person, each day and that pt_hrs > = 0.

  If the first date to a person is be a Friday, then that person is not counted as present the day before.  Similarly, if the last day is a Friday, they will not be considered as present the next day, so they can be counted as absent on Friday, even though they were not really missing the Thursday or Saturday.  This can be important if you filter by dates.  Most filtering can be done in the subquery, but filtering dates must be done later, after the analytical function of the SUM is calculated.

• Week, month, quarter and year calculation between two days with a quantity?

  I have a problem that I can't solve.
  
  Users enter a forecast (quantity) and a validity period between two dates.
  Expected quantity is always a monthly forecast.
  
  The problem is that the user wants to see the forecast by week, month, quarter and year.
  
  
  Material |     Quantity |     Date_from | Date_to
  Label45 |     1500 |     2009-09-01 | 2009-12-31
  
  
  How can I easily calculate the amount so that the user can enter e.g. week 2009.41 and see the forecast this week?

  You should test for your specific environment, but I would be very surprised if a function has surpassed SQL directly.

• Format of day, time of year, week, in figures

  I would subtract one date from another. Number return weeks and days and I'd years, weeks and days. Formatting will not allow adjustment of the year. Any suggestions?

  Hi max,.

  I suspect that the unit is not available for the same reason 'month' isn't available, unlike the week, day, hour, minute, and second, it is not a stable unit. Conversion from weeks to days gives the same result for weeks in February 2004, as it does for weeks in July 1918, Conversion from months to days may require multiplying by 28, 29, 30 or 31 for one month, or a value with a fractional part for a period of more than a month long conversion (although this period was an integer when measured (or counted) in months.)

  You can get an approximate value in doing some math.

  In the example, the end result is a text string. Formula below.

  

  C2: A - B

  D2: QUOTIENT (DUR2DAYS (C2), 365.25) & "is" & QUOTIENT (MOD (DUR2DAYS (C2), 365.25), 7) & "w" & MOD (DUR2DAYS (C2), 7) & "d" "" ""

  As mentioned, this is an approximation, and it is a text string, OK for display, but not useful (or usable) in all other calculations. A 'curiosity', more than anything.

  Kind regards

• Help! My Macbook Air has a high memory pressure.

  Product: Macbook Air in early 2015

  Plug-

  256 GB of flash storage

  1.6 GHz processor

  4 GB memory

  OS X Yosemite - Version 10.10.5

  A few weeks memory of my Macbook Air pressure continued to increase, most of the time he was in the green zone, but it has been several times that I had the pressure of memory to be in the yellow box with a few tabs in Google Chrome. In addition, the Kernel_Task continues to rise as it was around 380-390 MB a few weeks ago and now he's moved more than 500 MB. I tried to restart and stop the computer several times as an attempt to decrease the Kernel_Task and even thought that the memory pressure is high, the CPU doesn't have a lot of problems, because it is essentially inactive between 65 and 80 percent.

  What it looks like without all the eleven (shown) Google Chrome processes running? You should never see Swap used, and that tells me that you are using too many applications for your 4 GB memory available on your machine. With this RAM limited, you have to be very selective of what applications and browser tabs are open (you use) quit everything.
