Simple Formula SAE car DAQ Question

Im on a Formula SAE team, and for those of you who are unfamiliar with it, we design and manufacture a formula-style race car for competition against 120 other schools from around the world.
To the point - Im interested in creating a Data Aquisitiion system for the car. We already have a standalone Engine management computer so there are many sensors that go to that that to tune the engine. The DAQ i want to create is more for analysis purposes after various track events. For instance brake temperature, wheels speeds, acceleration (3 dimensional), yaw rate and that kind of information would be gathered by the sensor.
From my understanding LabView would have the ability to process the data and display what i want (aka, known acc
eleration, can use algorithm to find velocity), not to mention export the log so i can put it into Excel.
I was wondering if someone could reccomend a DAQ board i should look at. Also i was wondering if there' a possiblity for me to create this to stream and log the data on some internal onboard memory and NOT require a laptop to be hooked up to it the whole time. Ideally it would be standalone, and after a run i'd hook it up to the laptop and download the info (or if i got fancy, do it wireless as it occurs)
thanks for your time

FSAE,
LabVIEW will be a great tool for analyzing and presenting the information you gather from your car's sensors.
If having a laptop is an option, then one of our E-Series Multifunction cards would be a great solution, specifically the 6062E.
If you do not want to have a laptop then our compact fieldpoint are stand-alone acquisition systems that can be battery powered and have onboard memory to log data. They have rugged construction and have multiple modules you can connect for different types of measurements.
Over 10 Schools this year used our fieldpoint modules for gathering data on their 'Future Truck' Vehicles.
Contacting your local NI Sales Rep will be a great starting place for determining the type of equipment that would be best.

Query on simple formula write in transformation

Hi Bw Experts,
i am loading 0calday(20100401) to Standard cube(BI 7.0) from flat file.In the cube output i need only month and year(i.e 04.2010).I have to write the simple formula in transformations on 0CALDAY Field.What is the formula i have to write?
Could you please help me out?
Thanks

Hi,
you can achive this using the Filed routine or formula
DATE_MONTH(0calday) which will display month and year.
or write filed routine
RESULT = TRAN_STRUCTURE-0CALDAY+0(6). (BW 3.x)
RESULT = SOURCE_FIELD-0CALDAY+0(6). (BI 7.0)
Regards

Help! Simple Formula, Unique Output?

Post Author: kjameson70
CA Forum: Crystal Reports
In order to save space, I am creating a simple formula to include a company name, location, contact & phone instead of putting each field into a Text Box, which makes the Detail section of the report the same size whether data is reported or not.
Creating the formula is easy, but I want each field to print on a new line, instead of in the same row or to wrap.
How do I tell the formula to go to the next line? **
Current Formula: + + +
Preferred Result: Company Location Contact Phone
Not: CompanyLocationContactPhone2
What needs to be done to get the Preferred Result?
This result is one of many columns on the report.

Sort descending a column generated by a simple formula?

I have just upgraded to Numbers 3.2 from '09 and I have discovered this nasty problem where I can not “sort descending” a column generated by a simple formula.
Imagine the sequence 1, 2, 4, 8, 16, 32, 64…
— Let's add the first number, “1” in B1
— Click on B2 and make it equal to B1*2
— And so on, click your B2 cell and drop to bottom.
We get this nice succession:
OK. Now imagine we want to “sort-descending” this. We press on top and choose the descending option. And then we get this annoying result:
How I can to fix this problem?
This worked perfectly on previous Numbers versions ('09) and of course in Excel or OpenOffice. And it's a very “simple” and common feature.
Or maybe I'm forgetting or misunderstanding something?
Thanks for your support :-)
Cristóbal Vila.

Sorting has changed since the previous version.
You can sort this by selecting the column with the sequence, then copy
then select the menu item "Edit > Paste Formula Results"
now sort
another way is to place a "count" in column A... 0 thru whatever
and place a formula to computer the power of two from that count:
In this case I entered 0 in cell A1, then 1 in cell A2
select cells A1 and A2 and fill down as needed by dragging the yellow dot that appears when you hover the cursor over to bottom edge of the selection
In cell B1 I entered the formula "=2^A1"
no select cell B1 copy
select column B, paste
now you have a sort-safe table and may sort as needed

Creating a single variable from a simple formula

Hi guys,
I'm ploughing my way through the basics of expressions, constantly running into syntax errors as I still haven't found out the logic behind it all. It is still a great mystery to me when to use spaces, [ ] { } and ( ) not to mention =.
I was trying to create a variable called "y" from a simple formula. My scripting looks like:
veloc = 3;
amplitude = -5;
decay = 0;
y = amplitude*Math.sin(veloc*time)/Math.exp(decay*time);
[value[0],y[1]]
But whatever brackets and things I put around this formula, whatever spaces or newlines, somehow AE doesn't accept it. When I replace the formula for a wiggle, the fifth line is accepted, and when I replace the "Y" in the fifth line for "value" there are no errors, so obviously AE considers the formula not valid. What is the difference between the output that wiggle(,) gives and the output of this formula? How should I write this expression? Is there any website resource where the logic behind the bracket, spacing, newline, order etc. of this script language is demystified? And I mean really at basic, really baby level. I am pretty good at maths, but the programming hieroglyphs and their secret rules still don't make sense to me.
Any help is greatly, greatly appreciated.

Hi Mylenium, thanks for your fast answer. I tried both
veloc = 3;
amplitude = -5;
decay = 0;
y = amplitude*Math.sin(veloc*time)/Math.exp(decay*time);
[y[1]]
and
veloc = 3;
amplitude = -5;
decay = 0;
y = amplitude*Math.sin(veloc*time)/Math.exp(decay*time);
y[1]
but it's a big no-go still. I am really not getting the logic of the format. AE reports Class 'Number' has no property or method named '1', or that the outcome should be of dimension 2, not 1. Any more ideas?

Simple formula going nuts!

Post Author: echoi
CA Forum: Formula
I've a very simple formula that... for the life of me, I can't figure out whats going on with it.
It is in a subreport, and all it's supposed to do is look up a string for every record and if it matches, it adds on the value of a different coulmn. So here's the formula:
whileprintingrecords;numbervar hours;
if {Command.DESCRIPTION} = "Closed Labor Charges" thenhours := hours + {Command.QTY}else1234 // failure code
What's weird about this is that there are three records that should match the "Closed Labor Charges" but the formula returned the value for only one of those records. That's typical, I could have holes in my formula.
What makes it even more odd from here on is that if I bring up 6 more records that have "Closed Labor Charges", the formula returns "1234" which is the failure code defined in the formula. The records even contain the original match the formula found before and it's still returning a fail code.
What is going on here?

Post Author: V361
CA Forum: Formula
You may be able to peek into it a little by doing this. add /0 to the formula, and save it. (You will get an error message, but save anyway) run the report
whileprintingrecords;numbervar hours;
if {Command.DESCRIPTION} = "Closed Labor Charges" thenhours := hours + {Command.QTY} /0else1234 // failure code
The formula should pop up in formula explorer, and should show some values.
(Not a great way to trouble shoot, but sometimes it is handy to see what the Formula is doing. ) Also, after you remove the /0 and convert back to the orginal formula, add {Command.DESCRIPTION} to the report (next to the formula), or in the details, and unsupress them, this way, you should be able to see the value for {Command.DESCRIPTION} just before the formula is evaluated.

Simple formula using hierarchy ??

Hi,
I'm building a prototype cube to report salary payroll information. The cube is using a Wagetype Hierarchy that I've built. I would like to be able to do calculation <u><b>based on that hierarchy</b></u>. Ex: (non-productive hours) / (productive hours).
Is there a way to do what I want ?
Ps: I'm using BW version 3.1

To build my hierarchy, I used an external characteristic and each node represent a group of wage type. When I then build my query, I don't know how to use those nodes in a formula, since I don't see them in the formula builder.
Maybe my question is very simple, but please don't hesitate to give me lots of details, it may only be that I don't know the commands.
Thanks

How do I apply a simple formula to each column of a matrix?

I thank you all who have provided me with answers to my previous questions. As you can see I am a beginner. My new question is: I am trying to scale and centre the data in my X matrix (by column) using X = Xi - 1(Xmean). How do I perform this for each column so that my new matrix is scaled and centred? I appreciate your help and thank you very much in advance.

Simple array indexing using a for loop will work. Wire a 2d array into a for loop and the columns will be indexed automatically, then just do your math on that column and send it back out of the loop to get your 2d array back.

Another Car Stereo Question.

I know many of you guys still have problem connecting iphone to car stereo and
there's no clear solution for this issue. But,i'm still posting the question about this. O.k. Here's thing. I've been connecting 2nd gen nano to Alpine Car stereo using Aux cable with dock connector. But, Iphone does not work with this cable due to different pin layout.
So My Questions are:
Will Apple Universal Dock solve this problem?
Is there any cable or connector that changes pin layout?

The 30 pin connectors are not compatible with the iPhone when it pertains to transfering data like music. It will charge your phone but will not play music.
I have a Premier Pioneer deck and tried the 30 pin connection since the deck is compatible with iPods. However, it would not work. The only solution is to take advantage of your auxilary port and connect it to the headphones jack.
I do have to add that I had to grind away the plastic so that it would fit in the iPhone's headphone port. Only Apple would create the best phone out there and then neglect to allow us to use it like an iPod. Sigh.

Simple answer needed to complex question

I said "simple" because, although a Mac user for many years, I have no knowledge of the tech angle (which gets me in trouble regularly.)
In the last few days, my Safari started getting very slow on my iMac. I searched the forums and saw a suggestion that I discard a couple of files as well as "start in a safe mode" which required I do a restart with the shift key depressed.
Here is where the strangeness began. Upon a restart after the safe mode, it would fire up, then after a minute or so, it would shut down. This happened a number of times.
This is what I did: I started from my install disk and it fired up fine. I ran Disk Warrior and it resolved some issues, but said I had problems that could not be corrected.
I had installed Application Enhancer a week or so ago and had no problems with the restart.
Yes, I do have a number of 3rd party things, but have not suffered the failure to start that I now have.
I guess my question is this: Have I done something that cannot be undone by starting in "Safe Mode" and if so, how do I undo what has been done? Also, what is safe mode and could it have corrupted something?
By the way, I do not shut down any more or restart. I just let it sleep so that it will continue to run.
Please, any suggestions (other than the obvious "reinstall Leopard") would be greatly appreciated.
Thanks in advance!

Which iMac do you have (would be helpful if you updated your signature)?
I just recently read a post where several people had major problems with Applications Enhancer and needed to uninstall that app to get rid of the problems.
When you ran Disk Warrior, what exactly did it fix and what were the problems that could not be resolved? Can you post or copy the screenshots/messages?
Here's a link to the Apple article explaining safe mode:

Car charger question

ok, they apparently have no car chargers made specifically for the 3g, and some of the older ones are coming up with error messages...I went to the apple store and they said they don't know for sure and can't garauntee anything but sold me one that is basically a carcharger usb converter...He said these have been working...
It seems to work with no error message, but I do hear a VERY FAINT high high pitches hiss(similar to a misquito ringtone) when the phone's screen is on, coming from the charger, not the phone...
I remember this happening with my old clickwheel ipod car charger.
Main question...Is this ok, or is this abnormal? I only got it for emergency use and don't plan to use it unless I have too, untill the new ones come out...Also, where the heck are the 3g cases...They had a bunch of cases my grandma would wear...
***Also, I already lost my cloth, do they sell replacements.(I know any microfiber will do, but I liked that it said iphone on it and was the same size as the phone...lol

The hiss is ok, but you need to be aware that you need to turn your phone feature off while listening to the iPhone in the car radio (that is, put it in airplane mode). The iPhone is not shielded and will cause terrible interference with the car radio signal.

Very simple CVI-program and question

Hi
I have just started working with CVI and, as far as I can see, the principle behind the interaction between various elemements is similar as in Delphi. I have made a very simple example (User Interface Application), containing a square command button and a numeric. My idea was to push the button, whereafter the NUMERIC-control displays some number. However, I can't seem to figure out how to construct change the function that is executed when pushing the button. I tried double-clicking, right-clicking, etc.., but I couldn't figure it out. I hope my question makes sense.
Solved!

Simple PC to PC network question

I am trying to get some general information for an upcoming deployment.
Scenario - 2 PC's on the same subnet/VLAN connected to a Cisco catalyst L3 switch. Switch is connected to a router.
PC 1 talks to PC 2.
Does the traffic for PC2 go beyond the switch? Meaning, for example, does the MAC of PC 1 and 2 get put in the routers ARP table as well as the downstream switch?

Thanks Reza - told you it was simple :) One more simple question regarding Wake on Lan. We'll use the same scenario as my original post. My basic understanding of a WOL failure is this:
If PC1 sends a magic packet to PC 2, which has been in a powered down state for longer than the switches ARP table holds entries, the switch will drop the packet, since it would not get its ARP response, and would not wake up. Correct?
If so, are you aware of anything other than static ARP or a DHCP reservation, perhaps some logic on the NIC side of PC 2, that is capable of keeping it ARP entry alive on the switch?

Help with simple OS upgrade and backup questions for a dumb old previous PC user...?

Ok...have mercy on me, please...
I am not completely dumb, I know typical board etiquette, and I have searched for various answers (and found many)...but I just want to confirm my personal "research" and get all of this clear up before I proceed with this insanity. I know I could probably search more, but this is taking hours, because of all my various questions, one leads to 10 more...
I have an iMac with Mac OS X Version 10.5.8 (which, though not mentioned anywhere?...is apparently "Leopard", right? Told you I was dumb...)
Processor: 3.06 GHz Intel Core 2 Duo
Memory: 2 GB 800 MHz DDR2 SDRAM
My main goal: install an app that was in the Mac App store.
However, with Leopard, I can't access the Mac App store with Leopard, apparently.
I click on the Mac App store, and up pops up a Lion advertisement...telling me I should upgrade. Ok, fine...probably a good idea, anyway...
But how do you upgrade to Lion? Apparently through the Mac App store!
The web-redirects on the Apple site are amusing...taking me on an endless cycle...purchase Lion in the app store...click..."you need to upgrade to Lion"...OK...click..."you need Lion at the app store"...OK...click..."you need to upgrade to Lion to get to the app store"....etc.
OK...fine...google searches...ahh, I need to upgrade to Snow Leopard first, apparently! Yes?
(Maybe the Apple redirects should detect that I have Leopard, and direct me to a screen that explains that I must upgrade to Snow Leopard...and then Lion! Do you hear that, Apple? Thanks.)
Anyway...so here's my plan:
1) Upgrade to Snow Leopard
2) Access the Mac app store
3) Upgrade to Lion
Question A: With my iMac (specs above), is it really advisable for me to do this? Can my computer really handle Lion? It seems I barely meet the minimum with my intel core 2 Duo and 2 GB ram...yes? Is this a dumb idea, even if "OK"? I know that "minimum requirements" on a PC often meant: "Well, it will work...but it will be slower than a snail and crash if you run 5 programs at the same time" (which I usually do...) I don't want to upgrade if the "minimum" is really not enough.
Question B: If the answer to A is "not a good idea", then do I just need a new computer (i.e. better processor)? Or do I need more Ram? And can I add Ram to this computer, and is it relatively easy? I have added Ram to PCs tons of times, and you always have to determine type of Ram for your board, make sure they "match", or whatever, and then open up the machine and install. Kind of a pain, but once I have the "right" type of Ram, opening the CPU and installing is within my abilities. Will it be harder for a Mac?

Next:
When upgrading an OS on a Windows, you pretty much format the harddrive and start all over. Back in the day I was a PC user, there wasn't really a "great" way to back up programs and files, so this was a nightmare. You could NOT just back-up software. You typically had to re-purchase and install it all from scratch. Is this the same with Macs? Furthermore, personal files were scattered all over the hard-drive for the individual software...so trying to back all that up to get it back on the new system = nightmare! I hate PCs.
Anyway...so, my iMac has Time Machine. I am pretty ignorant about this, and based on my previous PC backup program nightmares, I have a distrust for it...and don't really understand how it works. But in any event, my external drive crashed a few months ago, and I haven't replaced it, yet. So, I am replacing it soon and will get Time Machine back up and running...setting it up again, etc...leading to question C...
Question C: When upgrading from Leopard to Snow Leopard to Lion, what is the best way to ensure I keep all my programs and files. My wife and I both access the computer, so two user accounts. Does Time Machine really do a good job backing up everything and all things? Is it just a matter of upgrade to Snow Leopard...then immediately to Lion...and then some sort of "Restore" from Time Machine? Anything for me to "watch out for"...or to do when I buy a new external hard-drive and setup up Time Machine for the first time on it, in order to make this work well? Will I have to re-install all the various applications I have installed on this thing? (like with PCs?)
Thanks for any sincere help.

Apple has discontinued support for 10.5, it's a plaque of our platform that Apple only supports the last two operating systems in circulation.
Where as on Windows you can run the same OS version for 10 years and get updates free (if not stolen), on a Mac we get one year, two tops now and if you don't upgrade and break all your third party software and hardware drivers in the process, then your denied security updates.
On top of that, the OS X upgrades tend to break your older hardware too, or slow it down so much that it drives you to want to buy newer hardware.
It's funny Apple places the AppStore on your OS X version along with iTunes and Safari updates, but then doens't supply necessary security updates, your machine may be compromised and here you enter vital credit card info, banking etc. thinking you have a secure machine.
My advice, since that's a 10.5 era Mac, is to upgrade to 10.6.3 via this disk, then use Software Update until clear. You'll get security updates and your present installed 10.5 software will work in 10.6 using Rosetta.
http://store.apple.com/us/product/MC573Z/A
Rosetta is not avaialble in 10.7 so it could be a lot of your software will no longer function
http://roaringapps.com/apps:table
I don't see the sense in you buying all new software for a machine that's at it's end of life stage.
You can buy software in the AppStore with 10.6.
Question A: With my iMac (specs above), is it really advisable for me to do this? Can my computer really handle Lion? It seems I barely meet the minimum with my intel core 2 Duo and 2 GB ram...yes?
You will need to buy 4GB of RAM to run Lion well, the 2GB is just a bare minimum, and your processor is a bit dated.
Lion 10.7 is certainly slower than Snow Leopard 10.6, in fact so many wanted to go back to Snow Leopard and one of the resons was Lion was slow.
So I wrote a User Tip, here, but the Tips were implemented only recently.

RAM is easy, you can buy it at Otherworld Computing or Crucial.com and install it yourself, there is a little door under the monitor.

Mac'soperaing system is seperate, it can be replaced or upgraded indepentantly of programs or user accounts on the machine.
There are some programs that install a kernel extension file at boot into OS X, those get knocked out, but those can be replaced with a new install of the software.
You should always backup your users files as those can't be repalced.

Question C: When upgrading from Leopard to Snow Leopard to Lion, what is the best way to ensure I keep all my programs and files.
OS X upgrades dont' affect User accounts but they can have a affect on programs installed, which most of your 10.5 programs likely will no longer work in 10.7
However they will (with a slight update) work in 10.6 just like before.
You need to backup regardless, I suggest a manual backup of users files to a storage drive, a 10.5 clone on another drive, the your ready to upgrade to 10.6
10.5 to 10.6 upgrade is rather painless, also 10.6 gives accelerated video drivers, so your machine will appear faster.
However once you install 10.7, you will slow down.
Does Time Machine really do a good job backing up everything and all things?
No, you shouldn't rely upon TM, have a multiple backup stragedy, TM files are hard to access directly.
Is it just a matter of upgrade to Snow Leopard...then immediately to Lion...and then some sort of "Restore" from Time Machine?
No need to restore, OS X upgrades and leaves everything else in place, just some programs (with 10.6) or a lot (with 10.7) when you try to launch them they will fail.
Also when you connect TM it will do a substancial change to reflect the new boot drive.
If you were using TM as a "storage drive" thinking you can use the archived versions later, that wil change upon the new OS X upgrade.
But in any event, my external drive crashed a few months ago, and I haven't replaced it, yet. So, I am replacing it soon and will get Time Machine back up and running...setting it up again, etc...leading to question C..
You need not only TM drive, but a bootable clone and user files on a storage drive.
 Most commonly used backup methods explained
Will I have to re-install all the various applications I have installed on this thing? (like with PCs?)
No, depending upon what OS X version you stop at depends how many programs no longer work.
You will have to buy a lot of new or upgrade versions with 10.7, not so with 10.6 only updates mostly because of Rosetta on 10.6 and not on 10.7
My opinion, since that machine is a bit dated, is to upgrade to 10.6, Software update to 10.6.8, and stay there.
Later on 10.8 is being released after this summer, you may want to consider getting a new machine with 10.8 a few months later to ensure all the bugs are worked out of it.
Your not a comptuer savvy person, you like most Apple users expect your machine to "just work" I think going to 10.7 will be a bad experience for you.
10.6.8 will server your needs until 10.8 is released and on new hardware where Apple will hold your hand for free for three months, 3 years with AppleCare.
Your not a "OS X upgrader type of a person" and Apple needs to get of thier collective assets and pay better attention to it's most common users.

Simple java/mysql database application question about triggers

I am planning a new database application using java and mysql. I may want to use some triggers to automatically update the tables when a change is made. my question is this: If I write the trigger, and I use Java to modify the database, will java automatically pause and let the trigger finish doing its task before it continues? what if it writes more to the table before the trigger is finished modifying the table? how do I get java to pause and let the trigger finish?
thanks for your response

It doesn't have anything to do with java at that point.
When you execute, for example, an insert statement, then the database executes that statement. The database (not java, not the driver) decides with that statement is complete. Control returns to java when the database decides that execution is complete.
And except for tricks that one might do (or attempt to do) via SQL or triggers then when the statement execution finishes then everthing has completed running.
