How to account for a broken sensor

I have 3 sensors coming from 3 com ports to my lab view program. I have all the sensors going into the same loop for the data to be time stamped and saved. Currently if one of the sensors stop working the program slows dramatically and does some weird things since no data is coming in.
So, I was wondering if someone could suggest a way to put NAN values for when a sensor stops working or gets unplugged from the computer so that the program will continue to work properly for the rest of the sensors. Also, it would be nice if I could find a way for the program to check occasionally to see if the sensor has started working again.
Thanks for your help.

The question about whether you can shorten the timeout depends on the device itself. How long does it usually take to respond? How consistent is that timing?
the first step you should take is to handle/log errors so that you know what is happening. When it fails, is it a communications error (e.g. serial read returns an error), or is it a functional problem (instrument returning NaN codes)?
If this CSAT3 is the campbell sonic anemometer (http://www.campbellsci.com/documents/manuals/csat3.pdf), make sure you read and understand the serial protocol it implements very well. Note especially table B-8 where they give the codes for "not available" and "lost trigger". Since the 5th word is used one way for these fault conditions and another way for normal conditions, if you aren't looking for 0xF000 or 0xF03F in word 4 (and 0x8000 in 0-3), you'll wind up trying to decode its NaN signal as -65.536 m/s.
I can't see your subVIs, so I don't know how you've configured it, but the timeout is a setting you apply to the serial connection when you initialize it. Default is usually 10 seconds.

How to account for and set the temperature in testing

The problem is this: I'm setting up an airflow resistance test and I need to account for temperature and barometric pressure. However, I don't know how to setup LabVIEW to account for these variables.

Devont:
Actually this issue is a fairly complex problem in aerodynamics. I am
an aerospace engineer who has developed computer code for this very
purpose in a couple of wind tunnels. When you say you are setting up
an airflow "resistance" test, what physical (aerodynamic) properties
are you trying to measure? Tunnel flow velocity? Mass flow?
Aerodynamic properties on a test model? (lift and drag coefficients,
center of pressure, gross forces?)
If you are trying to measure air flow velocity through a wind tunnel
test section, then the next question is what type of sensor system are
you using to do this? A pitot-static probe? A hot wire anenometer?,
an LDV (doppler laser)? Each has different techniques for getting
back flow properties.
Also what kind of tunnel is this? Low speed subsonic (say less <100
M/s) Mid speed subsonic <0.6 Mach? Transonic 0.8 to 1.2 Mach?
Supersonic 1.2 to 4.0 Mach? Hypersonic (say >4.0 Mach?) This will
make a great deal of difference in computing flow properties.
Mach number is a ratio of the flow velocity to the local speed of
sound where;
M=v/a where a is the speed of sound.
a=(gamma*r*t)^0.5
where gamma is the ratio of specific heats Cp/Cv, r is the gas
constant, and t is the absolute temperature. Gamma is a constant up to
about mach 4 but really starts to fall apart after that so this speed
of sound equation becomes a lot less useful for hypersonic analysis.
At low speeds gamma for air is approximately 1.4, r is about 287 for
air. At STP, the speed of sound is about 340 meters/second.
What is the scale of your tunnel? What is the density altitude of
your tunnel? What is the fluid medium in your tunnel? (Is it regular
air or something else?) These play into computing flow properties
because they affect a dimensionless flow property called the Reynolds
number which affects how the flow in the tunnel behaves.
You will need to consider also humidity which affects the density of
the fluid medium in your tunnel. Water vapor has a molecular weight
of 18. Dry air (0% RH) has a molecular weight of about 28.9. The
more water vapor you have, the lighter the sample volume of "air" will
be. The ability of air to retain water vapor is a function of
temperature, so a relative humidity of 100% at 0 degrees C will
contain much less water vapor than a relative humidity of 20% at 30
degrees C.
Because of something called the "boundary layer" the velocity profile
will be faster in the center of your tunnel than at the walls. It
will resemble something like a U shape for higher Reynolds numbers and
for very low Reynolds numbers may look more like a parabola. Reynolds
number is computed by:
Re=rho*V*L/mu
where rho is the air density, V is the flow velocity, and mu is a
property called the kinematic viscosity which is a function of
temperature.
The Reynolds number, like the Mach number, the Nusselt number, and a
few other fluid dynamics properties is a dimensionless ratio. Flows
with a similar dimensionless property should behave more or less the
same. This is called similitude.
Mass flow calculations first require that you know the air speed
profile of your tunnel and then you will need to compute the density
of the air in the tunnel and then perform an integration process to
calculate the actual mass flow through a particular plane of interest
in the tunnel.
Also, even when you put a test probe into the tunnel to measure the
flow in the tunnel, this will interfere with the free flow to a
certain of the tunnel. To minimize this, the test probes have to be
carefully designed and their size needs to be much smaller than the
overall tunnel dimensions. Later when you put a test model in the
tunnel, it and it's mounting system will also have an interference
effect on the tunnel that has to be accounted for.
To give a simple (perhaps an overly simple) answer to your question,
temperature and barometric pressure will play into your problems of
computing forces in that they affect the density of the fluid medium
in your tunnel via the unified gas law (which is a combined expression
of Charles and Boyles laws for perfect gases):
PV=nRT
or
Pv=rT
where rho, the density is the inverse of v, so this is sometimes
written as:
P/rho=rT
This only applies for perfect gases though. A perfect gas is one
where the constant pressure and constant volume specific heats (Cv,
and Cp) are fixed. The hotter and more dense the fluid medium, the
less true these equations become.
Temperature in these equations doesn't mean the common ways that we
ordinarily talk about temperature when cooking or talking about the
weather. Instead of C or F, temperature in the gas law must be on an
absolute scale such as Kelvin or Rankin. 0 degrees Kelvin or
Rankine=-273.15 degrees C or -459.67 degrees F. One Kelvin degree=1.8
Rankine degrees but both start at the same point of absolute zero.
For standard atmospheric conditions (called STP for standard
temperature and pressure), 1 cubic meter of air weighs about 1.226 kg.
You have to calculate the density of air at non standard conditions
by solving algebraically for the above gas law equation.
r is called the gas constant and can be derived from the universal gas
constant R (8314 units I can't remember of the top of my head but it
involves kJ/kg.mole or something like) by deviding by the molecular
weight of the gas in question. If the gas is a mixture then you will
have to apply the partial pressures rule to come up with an averaged
molecular weight of the mixture. Dry air contains mostly nitrogen
which has an atomic weight of 28 (about 79%), and then oxygen (about
20%) which has an atomic weight of 32, and the balance (about 1%)of
inert gases (Helium, argon, krypton, etc.) which have much smaller
atomic weights. For dry air r (small r that is) is about 287.
If the air is not dry, then you have to account for the water vapor in
the air by figuring out what partial pressure of water vapor is in the
air and then performing an average between the water vapor portion and
the other components of the air. Wator vapor only has a molecular
weight of 18 (1 Oxygen + 2 Hydrogens=18) and so is lighter than dry
air and tends to make the air less dense.
The partial pressure of water vapor that can be supported in the air
is a function of temperature that more or less grows exponentially
with temperature. I'm sure if you search the web you can find several
empirical equations for this. Relative Humidity (RH) is an expression
of how much water vapor is in an air sample versus the maximum that
can be supported at the current temperature of the air sample but what
you really want is the partial pressure of water vapor in the air.
There are sensors that can give this to you by measuring the
electrical conductivity of the air. Dry air is actually a very good
insulator, whereas water vapor decreases the insulating property of
the air.
All other things remaining equal, increasing the humidity will
decrease the density of the air.
All other things remaining equal, increasing the temperature will
result in decreasing density while decreasing temperature will result
in increasing density. If the temperature in your tunnel is different
than standard then you will need to account for this.
Tunnels generally heat up the air by the way when they accelerate the
air through the fan and also through boundary layer friction with the
tunnel walls. Many tunnels actually have heat exchangers to keep the
air from getting too hot. You will need to make sure you measure the
temperature at the same point thats you are measuring the static and
stagnation pressures in your your tunnel so that you can account for
its effects. Standard temperature is 15 degrees C or 59 degrees F.
For conversion purposes, 15 degrees Celsius =288.15 degrees Kelvin= 59
degrees Fahrenheit=518.6 degrees Rankine.
All other things remaining equal, increasing pressure will result in
increasing density, while decreasing pressure will result in
decreasing density. Barometric pressure is usually given by the
weather service as inches or millimeters of mercury or sometimes
millibars. For conversion purposes, 29.92
inHg=760mmHg=1000millibars=14.7 psi= 101325 Pascals pressure. If the
pressure in your tunnel is different than standard then you will need
to account for this.
Depending on tunnel velocity, you will also have to consider
stagnation versus static properties. Stagnation properties are what
you measure if you bring the flow at a point to a complete stop, i.e.
the kinetic (as opposed to random thermal) energy in the sample is
completely converted thermal energy. How you do this depends on what
speed of sample you are trying to measure and is the subject of whole
books. Suffice it to say that at low speeds there is little
difference between stagnation and static properties but the faster you
go, the less resemblance they bear to one another.
Compressibility is another issue. At low speeds air is
incompressible, but at higher speeds v>100m/sec, compressibility
becomes worth accounting for in your measurments.
At higher temperatures and velocities, (high supersonic, or
hypersonic, or high temperature >500 degrees C), the constant pressure
and constant volume (Cp and Cv) specific heat assumptions break down
and so does the gas law. The simplifications that can be made for
using the ratio of Cp/Cv (called gamma) also break down because Cp and
Cv and therefore gamma all stop being constants. Solving flow
problems in this regime becomes much more complex requiring numerical
models for Cp and Cv and requiring numerical (as opposed to simple
analytical) methods to compute flow properties.
Once you know the flow density, you can calculate air speed. For
lower speed low temperature tunnels (low subsonic) you can use a
simple incompressible Bernoulli equation for converting pitot-static
pressure to air speed. At higher speeds and temperatures this depends
on the regime (transonic, supersonic, hypersonic, etc.)
The Bernoulli equation is simply:
Pstagnation=Pstatic+1/2 rho * velocity^2
For lower speed supersonic, the isentropic gas relations are sometimes
used.
In any event, you have to be sure to get your units right. If you use
metric, pressure is Pascals (Newtons/m^2), rho is kg/m^3 and velocity
is meters/sec. It's harder in U.S/U.K units because of conversions
between slugs and pounds etc.
Also you have to consider the concept that there will be a steady
state average that you will measure and a transient/turbulent portion
that will occur for each parameter that you measure (temperature,
pressure, RH, etc.) that you will need to account for.
Once you know the air speed and the density, you can compute their
product - mass flow. Mass flow then can be used for other purposes
such as calculating performance properties if you are testing a jet
engine or propeller or something.
Hot wire anenometers work by heating a wire and measuring the
resistance of the wire. The faster the air flow past the wire
filament, the more it will cool. I don't remember the equations off
of the top of my head but I believe that there is a square rule
involved. Hot wires work better at lower speeds than pitot-static
sensors but both become less effective the slower you go.
LDV's are neat, high tech toys that I haven't had a chance to work
with yet but they measure the airspeed by measuring the doppler shift
in the light emitted by a laser beam going through the flow, much like
doppler (WX-88) weather radar works. They actually measure the speed
of the air more directly than the pitot-static or hot wire methods are
probably simpler to implement from an equations point of view but they
are very very expensive.
In conclusion, I know I have written a lot of stuff up here that
probably sounds pretty intimidating with regards to solving your
problem. It would help to eliminate some of this by telling us more
about your test problem so that we can make the appropriate
simplifying assumptions. Tell us more about the details.

Price difference due to changed POD qty how to account for this ?

Hi Gurus,
I am having delivering goods after activating POD at item level and customer master. My delivery document the qty is 10 tons , Due to pilferage transportation loss etc the qty is reduced to 9.5 tons. After confirming POD , i am billing for 9.5 tons. The difference of 0.5 ton how to account. I am also maintianing the VPRS condition in my pricing procedure. How does it affect my costing ?how to do the price diference posting and where?

How to account for Shipping charge not used during Purchase Process?

A PO was created. PO had purchase item price, tax, freight with shipping and insurance.
Goods received.
PO invoiced for item pricetaxshipping.
However, insurance was not paid for in Freight.
Question is how can we return the amount back to Vendor?
The Goods Received Document is open as shipping amount is still remains to be accounted for. What is a good for to account for this shipping charge if not returned to Customer.
Thanks.

Hi Gordon,
I think it was my mistake.
This is what is the conclusion like you suggested.
Whenever Invoice is less than po, it automatically adjusts the Inventory of Finished Goods Account on credit side with the amount we paid less.
Thanks. So no issues here.

How shadow accounting for IFRS can be done

Hello all,
When cost of implementation of IFRS are huge and requires new G/L, Is it possible to have a shadow accounting practise.
Lets say we create a financial statement version based on IFRS accounting structure.
1. how the apc posting to be made for IFRS depreciation ares.
2. how the depreciation will be posted in this case if the IFRS depreciation area is made as real.
Regards,
Keith.

Hi Keith --- First a couple of points for you. I would not necessarily assume the cost of IFRS adoption will be "huge" as the cost and complexity of the project will be dependant on your own existing landscape and the industry and country where you will be adopting IFRS. Really the best way to scope the complexity and cost of the IFRS adoption project is to work closely with your audit/consulting partner and SAP to really determine what the best course of action should be. Basically, the sooner you engage the better as it will save time and money.
Regarding you second point regarding the SAP General Ledger (NewGL). Although it is the recommend solution it is not a requirement. There are other solutions available that utilize a single ledger approach. For example the use of the "Account Based" configuration approach for the GL and utilizing the reporting capabilities found within SAP BusinessObjects may be the best approach for your situation. See SAP and IFRS: FAQ document at https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/60eecedc-7ff0-2b10-b2be-c329c1114298
As far a reporting from a "Shadow Accounting Practice" the SAP General Ledger does offer the ability to set up multiple ledgers which can be used for reporting on different accounting standards. For example set the Leading Ledger to report on IFRS and another non-leading ledger to report on Local GAAP. If it turns out that the adoption of the SAP General Ledger is not the best course of action at present then you could use the tools found within SAP BusinessObjects to report on the various legal options.
As far as IFRS reporting from the Depreciation Areas goes, this would require the set up of multiple deprecation areas tied to separate ledger or specific account groups within your Chart of Accounts. Again for more specific information regarding this questions I would suggest contacting your audit/consulting partner or SAP Field Services for further guidance

User input; how to account for unlimited names typed in

So, I finally figured out how to write a program that, given the input of three names, can replace any one of the given names with anything the user wants.
My problem is that it only works for three names, and apparently, my professor wants the program to work for as many names as the user puts in (ie, a user can input 10, 100, 5000 names, and the program will replace any one of those names with anything else).
I have no idea in the world how to do this. How can you extract the name "pieces" from the user-inputed string?
Help is GREATLY appreciated!
Here is the code for the three-name-only program, but I don't know if it can be modified.
import java.util.Scanner;
public class Rename
public static void main(String args[])
Scanner in = new Scanner(System.in);
String name, first, middle, last, space;
space = " ";
System.out.print("Type your whole name: ");
name = in.nextLine();
first = name.substring(0, name.indexOf(space));
name = name.substring(name.indexOf(space)+1, name.length());
middle= name.substring(0, name.indexOf(space));
last = name.substring(name.indexOf(space)+1, name.length());
System.out.print("Which part don't you like? ");
String dlike = in.nextLine();
System.out.print("What should it be changed to? ");
String rep = in.nextLine();
String kirt, john, bob;
kirt = first.replace(dlike, rep);
john = middle.replace(dlike, rep);
bob = last.replace(dlike, rep);
if (dlike.equals(first))
System.out.println("New name: " + kirt + space + middle + space + last);
else if (dlike.equals(middle))
System.out.println("New name: " + first + space + john + space + last);
else
System.out.println("New name: " + first + space + middle + space + bob);
}

Do you have to read in within the program using Scanner? If not, then you could also just let the user submit the names using the args[] array in your main method. This way the names automatically come in a array as long as necessary with all the names.
Just to clarify:
User types: java Rename John Bob Roger Whoever
And in your program:
public static void main(String[] args){
// args now contains "John", "Bob", "Roger", and "Whoever"
// do all your stuff
}

How to account for shifts and time zone differences in an EPC simulation?

BPA EPC Simulation results add up processing times and wait times, without regard to shifts or time zone differences between tasks. Does anyone have a technique to deal with shift work or time zone differences? For instance if a task takes 6 hours to complete, the worker can do it in one shift if the task is received within the first two hours. However, if the task arrived near the end of the work day, the worker may work on it for the balance of the shift and then continue the work the next day. The value of a Static Wait Times then depends on when the task is received by the worker. Any ideas on how to realistically model this?
Similarly, if workers pass tasks between them in difference time zones, static wait times may or may not accurately reflect the impact on thru put time. Any ideas on modeling this?
thanks
Rodger Martin

Thanks Michael -- you've helped me with the project before (back in May of this year).
I started this project as a newby back in 2010 and was a bit overwhelmed (i.e. just happy to get everything into FCP and be able to edit.)
I'll try the media manage solution, but if that doesn't work I think I'll live with the one-frame drift. I'm assuming
the only other alternative would be to go back to all the original video and audio files; transcode using Compressor, and then re-synch with Plural Eyes and go back in to match up the edits?
Thanks to your continuing help, I should know how to set things up correctly from the get go for the next one!

Accounting for varying values in Data merging

Hi everyone,
I've been asked to create a template for a degree certificate. So far I've created an InDesign document and used data merge to import the data from a .csv file. I've also used GREP styles to resize the name of the degree when it's longer than a certain number of characters. So far so good.
My question has to do with how to account for different categories of certificates. Let me explain. In my spreadsheet I have thre types of certificates A, B, and C. Each category triggers two specific bits of text. So for example:
When Cat = A
the following blurb appears at the top of the certificate:
WHEREAS THE UNIVERSITY OF NOWHERE HAS BEEN EMPOWERED BY ACTS OF THE LEGISLATURE OF MARS TO CONFER DEGREES AND AWARD DIPLOMAS OF THE UNIVERSITY
and the following text appears just before the name of the degree:
HAS BEEN ADMITTED BY THE UNIVERSITY TO THE DEGREE OF
When Cat = B
the following blurb appears at the top of the certificate:
WHEREAS THE UNIVERSITY OF NOWHERE HAS BEEN EMPOWERED BY ACTS OF THE LEGISLATURE OF MARS TO CONFER DEGREES AND AWARD DIPLOMAS OF THE UNIVERSITY
and the following text appears just before the name of the degree:
HAS BEEN AWARDED THE
When Cat = C
there is no blurb at the top of the certificate.
but the following text appears just before the name of the degree:
HAS BEEN AWARDED THE
I first thought of creating IF formulas in Excel but it doesn't work because I don't want the result to appear in the data, I want it to only appear once merged in the InDesign template.
SO THE QUESTION IS:
Is there any way to specify IF THEN values directly in the InDesign document? If not, does anyone have any idea if what I'm being asked to do here is even possible?
Any help or nudge in the right direction would be greatly appreciated,
Chris

Hi Christine,
I'll need to work through the example, but it would be that the blurbs are on thier own separate layers of page 1. And the data fields are simply on their own layer, still on that page.
That's as far as I got in a quick perusal of his example. I plan on recreating the example tonight when I have a bit of my own time to spend. I suspect it will be a lot more clear following the example, bit for bit. If it does work out as it seems it should, I can think of a. coupon job I merged that would have (maybe) been easier than the 5 merge files I ended up with.
I do want to mention, pointing back to my earlier comments, if there is anyway you can work with the IT people to produce a clean file ready for you, I would do so. Colin mentioned XML, and that is what I would strive for in this situation. But XML is a bit like being thrown into the deep end of the pool and learning to swim at the same time.

How to prepare for A3 install? Frozen with trepidation from reading here

I'm mad I bought my A3 so quickly. I have early adopter regret. I tend to jump in early but now that I've been using Aperture for years the stakes are high.
I have been sitting here staring at A3 and drooling about using it for a couple of weeks. The more I read in these posts the more confused I get. I don't understand migrating by project, yet I think that's the only way I'm going to keep my sanity.
First, a description of my set up. I have an early Mac Pro with only 2 GB of RAM. I have all my photos reside on my second 1 TB internal HD (does that make them referenced?) and about 300 GB of free space on my primary drive. My library is about 70,000 photos taking up 286 GB.
I didn't understand the concepts of vaults when I started using A1. I now want everything in one vault but I started out making a few vaults. My first vaults now are ghosted and say they are disconnected even though the external HDs are hooked up. My new 'master' vault only says my library is 225 GB, so I don't know how to account for that discrepancy. What photos are missing? Therefore I have concerns that I'm not completely backed up.
I would LOVE to have a 4-5 external HD RAID system (another concept I don't understand) but I've looked at the prices and I'm not able to spend that kind of money. It sounds wonderful and someday. . .
I don't want a regurgitation of what's already been posted, but given my brief description does anyone have advice to help me build my confidence and accomplish this upgrade.
PS - I am looking forward to using Faces and Places (to a lesser degree) so all the advice about turning off Faces makes me sad. Is there a way to have Faces work project by project instead of running through the whole library? I photograph people a lot so it will take a long time for it to process every photo.

Hi,
In my case I installed AP3 and honestly no crashes or major issues other than some slowness in AP3 but I see it's been solved with the updates and my workflow maybe helping too.
I run a managed AP3 library on a fast external drive connected via eSATA card to my MBP.
In your case I would say add more RAM (never hurts) although 2GB should be ok for now.
Leave your AP3 Library on the main drive and reference your files that exist on the second internal drive.
When importing, you have a choice as to leave in current location(so referenced)
or have AP manage library.
As far as the size of your library at 286GB, it my be a good idea to install another internal drive in the Mac Pro.
So
drive 1) Boot drive with OS and all your apps.
drive 2) AP3 Library
drive 3) Original RAW files that your AP3 library can reference-as long as you tell AP to reference the files upon import.
eventually maybe a 2 TB external drive (usually made of 2x1TB drives in one enclosure)
and this external can be used to back up your AP3 library on one drive and your original RAW files on the second drive.

How can I Migrate/Split itunes/icloud account for a large family now that they have family sharing

Ok, now that Apple has finally come out with family sharing I need to get things sorted out and I think it is going to be a mess. I have 6 family members (my spouse and 4 children) all sharing/using one itunes account. For parental reasons this made perfect sense. Now with the the advent of family sharing and such we have alot of sorting and migrating to do and I am very unsure how to go about it. Here is what we have.
Myself - I have a 64GB iPad 3 and a 64GB iPhone 5
Spouse - 64GB iPhone 5
Children - x4 16GB iPhone 5C (pink, blue, green, and a yellow)
We have had one itunes account now for several years, we used to have x4 16GB iphone 4's and a 16GB iPod touch 4 so we needed it to be shared at the time. We all have different Game Center ID's and Facetime/iMessages are all setup to the phone numbers (aside from mine which also uses the itunes e-mail). We currently have 1 upgraded icloud account with 200GB of storage on it (love the new tiers). So here are the questions.
1) How do I go about using and isolating all the devices so they can all use the iCloud storage? Right now if I try and setup backups by device under the what to backup there is no simple "Full Backup" option, they have all the categories separated. I cannot backup my daughters contacts without forcing a merging of them and so on. Same thing with Documents and Data. Would I need to setup a different iCloud account for each device now?
2) iTunes Music/App purchases. Now that they have a family sharing function I am assuming it would be a good time to separate all the devices (aside from my personal iPad/iPhone). If I understand correctly we need to setup a new itunes account for each and link them with family sharing, does this then allow us to disperse/move items from a singular to the multiple account (at least a one time option to move around) or would it simply be shared off the original account? My daughter for example will be 18 next summer and as such no longer under our care. How do we move her items to her account? She has a lot of purchased Music. Now keep in mind I am talking about an account for someone who was 12 when she had her first device and as such needed to be under her parents.
I just want to state that repurchasing things is NOT an option, and to be frank, according to Canadian laws pertaining to *licensing* we actually own the product if we paid for it and have the right to transfer the ownership thereof. This issue went through the courts regarding used copies of OEM editions of Microsoft Windows several years ago and they closed the legal *license* vs ownership separation.

Go to appleid.apple.com to manage the ID, sign in and select to the Name, ID and Email Addresses section, then change the birth date on the bottom right. At the present time you may not be able to enter the correct birth date, but others have had success changing the year to 2000, or the date to 1/1/2001, both of which will have child ID status.

HT204053 The entire family has used one itunes account for years. How do we all set up separate iCloud accounts now?

The entire family has used one itunes account for years. How do we all set up separate iCloud accounts now? Or should we? 5 macbooks, 2 ipads, 4 iphones, 2 itouch, 2 imacs. How does one decide what to sync, share and what not to? Green Jeans.

You need to start by understanding the distinction between iTunes and iCloud - Apple confuse the issue by referring to 'iTunes Match' as part of iCloud. It isn't.
You don't have to have the same login (Apple ID) for iTunes and iCloud; many people don't and there's no problem about it.
Your iCloud ID gets you email, calendars, contacts, iWork documents and PhotoStream syncing between devices.
Your iTunes ID gets you the iTunes Store, the App Store for iOS, the Mac App Store for OSX,, 'iTunes in the Cloud' (downloading of purchased items to any logged-in device) and 'iTunes Match' (uploading of songs not purchased in the iTunes Store).
Your family members can easily each get their own iCloud account to keep email etc. separate - in each case they will need a different non-Apple email address (a free one from Yahoo etc. would do) to set up the ID. If they are sharing a Mac they need to be using a separate user account.
They can have their own iCloud accounts and still all sign into the same iTunes account: or they can open their own iTunes accounts using their new iCloud Apple IDs.
BUT they cannot transfer items purchased under the present iTunes ID to different iTunes IDs.

How do I manage multiple iCloud accounts for personal iCloud Drive & personal calling?

Yosemite has the ability now to make and receive phone calls as well as to use an iCloud Drive to share documents across devices (similar to DropBox, but as you will see with one major customization flaw). These are wonderful featurew, however, unless I am following the directions incorrectly my computer with Yosemite has to have the same iCloud account as is used on my iPhone for iMessage (for calling) and for virtually everything else for iCloud Drive (ie there is no way to set-up a separate iCloud account for iCloud Drive).
Now for iMessage I use a private iCloud account, but for the iPhone itself I actually use an iCloud account shared with my family. Why? Because when we use a shared iCloud account we can share a number of things here such as:
Location on Find iPhone. This works way better than find my friends and also makes it easy for us to lock a device if it's stolen since all of us know how to do this.
Calendar not critical, but allows us to put some family events here
Notes, Very cool as we can share shopping lists which is very helpful when you show up at the grocery and want to know what to get or to Costco etc
Reminders Also very cool as we can create reminders for each other for when we get home or whatever
Files on iCloud Drive Yes there are some files that it would be nice to share and we can do this (ideally there would be multiple accounts for this)
Now I haven't really used iCloud Drive much but you can easily imagine how some documents I might want to share with the family on iCloud while other's I might not.
Now when you switch your Facetime iCloud account to the same as the iPhone that is one private iCloud account shared with an application on another device that uses the same iCloud account. That is NO PROBLEM. However, the minute you activate the ability to call phones it requires that you now have the SAME iCloud account in the main computer. Now BINGO I have a problem as noted above I want to be able to share certain things with other devices.
Does anyone have a solution or workaround?
Otherwise it seems the only thing to suggest is that Apple consider a feature enhancement that allows you to make cell calls from your computer WITHOUT switching the iCloud account to the main account. For that matter it would be very useful if they could figure out how to partition the iCloud features so that I can decide which iCloud account does what or like DropBox give permissions for certain things and allow the individual users to decide what they want and don't want.
Thanks.

Gail,
No you are not being dense, you are just trying to be helpful. I may not have explained the problem very well. Setting up a Family iCloud account works great! However, if that account name is also used for your iMessage, Facetime, and now cellular calls you have an issue with your calls going to the entire family (or worse the thing just not working), your iMessages if multiple phone numbers are trying to use the same icloud account usually get messed up, and their Facetime accounts might end up showing up as you instead of them. In fact, I think you can't call your family members in this situation and I'm not sure iMessage works very well either. So what everyone does is create a personal iCloud account for personal features such as iMessage, FaceTime, etc.
Now in theory I could co-opt the Family iCloud account for my calls, but then no one else would be able to use the call feature, because unless I'm mistaken you can't have multiple phone numbers attached to the call Forward and still have them recognize which calls to forward to which phones. If they don't care for this feature it might work (I'm experimenting now), but I don't think that's what Apple intended.
It is possible to do a switch, which may be what you are suggesting. This would involve creating a separate profile on the computer that is used for making phone calls. I would, however, still need to co-opt the iCloud account for just my number and worse I wouldn't be able to make any calls unless I was in that profile. One of the great advantages of calling from your computer is that you make the call while you are working on something else which is inevitably your work or your personal stuff which is NOT likely to be in the newly created family profile.
Thanks for the suggestion, but I hope this helps you understand either how little I understand of your suggestion or why it doesn't quite meet my needs.

It is not possible to create a new iCloud account using a Windows machine. You must create the account using a Mac (10.7.5 or more) or an IOS device (iPhone etc). Once that is done you can sign into and use the account on your Windows machine.

Help!

Deleting an iCloud account only deletes it from the Device, not from iCloud. In iOS 8, the name of this setting changed to "Sign Out" as that is a better reflection of what actually happens. Your iCloud data remains on the server, available to devices still signed into the account, but the device you sign out of the account on is disconnected from the account, and as a result, the iCloud data from that account is removed from the device. It will redownload to the device should you sign back into the account.
The only issue you'll run into when you switch between accounts is with my photo stream photos older than 30 days. When you delete (or sign out of) and account, your photo stream photos are deleted along with the other data from the account in question. However, unlike other data which remains on the server and can redownload to your device when you sign back in, my photo stream photos only remain in iCloud for 30 days. When you sign back in, you will only get back my photo stream photos added in the last 30 days (as older photos are no longer in iCloud to redownload). Like other account data, any my photo stream photos on your other devices signed into the account are unaffected by this. If you want to keep older my photo stream photos on your device as you change iCloud accounts, save them to your camera roll before deleting (signing out of) the account.

If you want to change your iCloud ID to another existing ID you'll have to delete the account, create a new account with the other ID, and migrate your data to the new account. To do this, first go to Settings>iCloud on your phone and turn all data you are syncing with iCloud (contacts, calendars, etc.) to Off. When prompted choose to keep the data on your iPhone. (If you are syncing iWork documents with iCloud, also open your iWork apps and turn off iCloud syncing and choose to keep the documents on your phone.) After everything is turned off, scroll to the bottom and tap Delete Account. Next, set up a new iCloud account using your other ID, then turn syncing for your data (contacts, etc.) back to On. When prompted, choose Merge. This will upload the data to your new account.
This will not move your photo stream, however. If you have photos in photo stream that aren't in your camera roll and that you haven't backed up anywhere else you will need to save these before deleting the account. To do this, open your photo stream album on your iPhone in the thumbnail view, tap Edit, tap all the photos to select them, tap Share, then tap Save to Camera Roll. You can then delete the iCloud account and your photos will stay in your camera roll.
