Any engineering students here? Question about data plotting

I was just wondering how you guys plot your data for work. I use Origin in XP all the time, but in OSx i haven't found a good counterpart yet. I need something that can produce plots which i can paste & reopen in MS word documents. I know Excel can do the job to some extent, but I'm looking for something closer to Origin.
Sorry, I just realized that I probably shouldn't have posted this in the Macbook forum. But, any input will still be appreciated.

I have to add another voice for Igor Pro. For 2D plotting it's superior to Matlab and it also provides quite a bit of analysis capability (though it is not as capable as Matlab in this area). The program is x-platform and you can easily exchange plots and data between Mac and PC versions of the program. I don't anything about Origin so I don't know if there are filters that can allow direct import/export to Igor Pro.
When presented with data in my job I approach it this way:
Tabular data in Excel because of the Pivot Tables and Data Filters. These are very nice tools for large tabular datasets.
Time-series experimental data in Igor Pro for plotting, exploration, presentation and some analysis. It's easy to write a small programs in Igor Pro that allow customized data exploration. It's actually easier than doing it in Matlab because of the way you can add multiple axes to plots. And this is where I always do plot prep for publication.
Frequency data or time-series experimental data in Matlab when I need specific Matlab toolboxes (e.g. control system, signal processing, system identification, etc.) Heavy-duty analysis is easier in Matlab -- if you own the toolboxes!
Although you can do data reduction in either Matlab or Igor Pro (and I've done it in both of them) you're probably better off writing your own data reduction if the datasets get really big (e.g. 100's of MB or GB's per data set).
The best part is that all 3 of these programs are cross-platform and I frequently move data and analysis programs between PC's and Macs. None of these tools, however, are professional-grade for statistical analysis. For that you still want SAS or SPSS or even R if your head works that way.

I have a question about Data Rates.

Hello All.
This is a bit of a noob question I'm sure. I don't think I really understand Data Rates and how it applies to Motion... therefore I'm not even sure what kind of questions to ask. I've been reading up online and thought I would ask some questions here. Thanks to all in advance.
I've never really worried about Data Rates until now. I am creating an Apple Motion piece with about 15 different video clips in it. And 1/2 of them have alpha channels.
What exactly is Data Rate? Is it the rate in which video clip data is read (in bits/second) from the Disc and placed into my screen? In Motion- is the Data Rate for video only? What if the clip has audio? If a HDD is simply a plastic disc with a dye read by "1" laser... how come my computer can pull "2" files off the disc at the same time? Is that what data transfer is all about? Is that were RAM comes into play?
I have crunched my clips as much as I can. They are short clips (10-15seconds each). I've compressed them with the Animation codec to preserve the Alpha channel and sized them proportionally smaller (320x240). This dropped their data rate significantly. I've also taken out any audio that was associated with them.
Is data rate what is slowing my system down?
The data rates are all under 2MBs. Some are as low as 230Kbs. They were MUCH higher. However, my animation still plays VERY slowly.
I'm running a 3GigRam Powerbook Pro 2.33GHz.
I store all my media on a 1TB GRaid Firewire 800 drive. However for portability I'm using a USB 2 smartdisk external drive. I think the speed is 5200rpm.
I'm guessing this all plays into the speed at which motion can function.
If I total my data rate transfer I get somewhere in the vicinity of 11MBs/second. Is that what motion needs for it to play smoothly a 11MBs/second data connection? USB 2.0 is like what 480Mbs/second. So there is no way it's going to play quickly. What if I played it from my hard drive? What is the data rate of my internal HDD?
I guess my overall question is.
#1. Is my thinking correct on all of these topics? Do my bits, bytes and megs make sense. Is my thought process correct?
#2. Barring getting a new machine or buying new hardware. What can I do to speed up this workflow? Working with 15 different video clips is bogging Motion down and becoming frustrating to work with. Even if only 3-4 of the clips are up at a time it bogs things down. Especially if I throw on a glow effect or something.
Any help is greatly appreciated.

Data rate DOES make a difference, but I'd say your real problem has more to do with the fact that you're working on a Powerbook. Motion's real time capabilities derive from the capability of the video card. Not the processor. Some cards do better than others, but laptops are not even recommended for running Motion.
To improve your workflow on a laptop will be limited, but there are a few things that you can try.
Make sure that thumbnails and previews are turned off.
Make sure that you are operating in Draft Mode.
Lower the display resolution to half, or quarter.
Don't expect to be getting real time playback. Treat it more like After Effects.
Compressing your clips into smaller Animations does help because it lowers the data rate, but you're still dealing with the animation codec which is a high data rate codec. Unfortunately, it sounds necessary in your case because you're dealing with alpha channels.
The data rate comes into play with your setup trying to play through your USB drive. USB drives are never recommended for editing or Motion work. Their throughput is not consistent enough for video work. a small FW drive would be better, though your real problem as I said is the Powerbook.
If you must work on the powerbook, then don't expect real-time playback. Instead, build your animation, step through it, and do RAM previews to view sections in real time.
I hope this helps.

New to smartphones and i have a question about data usage...

i bought my wife a droid 2, we are both new to these phones, ( i still have my ENVY3), but my question is, since she doesnt spend too much time on the web i got her the $15 data package, as i was told it should be enough for most people that are occasional web surfers. my question is though, if she has logged on facebook, since its constanly running and updating, would that mean its constantly using data?
thanks folks for any help

Yes, anything that updates will use data. This can be turned off when not in use (menu> settings> wireless & networks> mobile networks, uncheck mobile data) or place the power control widget on your homescreen and it can be toggled from there.

Report based on custom Query - Question about Data Source

Hello,
I am trying to create Crystal reports (EBO R3.1, Oracle 11g Database, CR2008) based on custom queries. Tried using different kinds of Data Sources but getting stuck once I export them to Infoview.
1. Using Oracle Server: This method works fine on my local & Infoview. But since I have lot of reports, I do not want the DB username/password associated to the report. I neither want BO to prompt username/pwd to my user.
2. Using ODBC(RDO):
Again, works fine on my local. Once I export to Infoview, it fails with this error: "Failed to open the connection"
Which makes sense, because the DSN is created on my local machine and not on the server.
How and what do I create on the server, so that the reports run?
I do not know if using ODBC(RDO) is even the right way for creating custom SQL reports.
I have been reading about Business Views, but not clear on how good they work.
My goal is to create multiple reports, using custom SQL queries which use some kind of connection to the database that can be managed on the
server in one place, and used by multiple reports.
Can any of you please help me here
Thanks,
Sowmya.

Thanks for moving it to the right forum!!
But, if I setup in CMC, a default username/password that the report needs....what would happen if my password changes?
I would need to go to each and every report and update the password.
I am looking for using one common "connection" for multiple reports. So that, when passwords change, all I update is in one central location.
Can anyone please help!
Thanks,

Question about dates shown in finder

I have a problem and need help.
First question is: what date is shown in default finder settings on files? Creating date , Modified or added Date? on Mac, Windows?
The problem lies here, I have to give clients JPEG picture files. we had to re-shoot (what the client does not need to know) The re-shoot was necessary because of a mistake I made:-( anyway ... I have to create zip folders to give him the pictures, but the create and modified dates do not change when zipped. Does anyone know how to change these dates( without re-render the files)?
Any help is highly apreciated!

Hi GM1941,
When using Finder>All Images, the ones that you have more than one copy of are images that you do in fact have more than one of. An image stored under the same name and possibly placed in another location from its original.
A good example would be if you downloaded all your images to a pictures folder on your desktop. From there you might copy a picture of a family member in a genealogical program and not rename it. There you have two copies.
If you opened the picture in Photoshop or some other image manipulation software and saved it in a different file format (ex: Tiff, PNG, PICT, GIF) you are again able to save it again- even to the same file- with out renaming it.
When you use the Finder to search for all images, remember that you are looking for ALL images on your computer, not just the ones in iPhoto.
The files listed under today, yesterday and last week are a "search" list of documents/files you have opened during those times, not another copy. But, they are connected to the item they represent and, if you drag them to the trash they will indeed be in the trash and can be deleted from there.
Good Luck,
John

About to leave to Cancun Mexico (yay!) - questions about data/wi-fi

Hey all!
I'm about to go on my first international trip with my beloved iPhone. I know the hotel has free Wi-Fi down there, and I'd love to be able to use the phone for email checking and other data stuff - but I don't want any surprises with international data fees up the wazoo or anything.
If I don't plan on sending text messages or make calls but just use the wi-fi features while down there - what should I do? Any setting I need to be careful with etc?
Any advice highly appreciated!
// martin

You should be Ok to go down there as is. A couple things you can do.
Are you just going to use the iPhone for WiFi and nothing else?
If so you have the possibility of removing the SIM card to ensure it hits no Cell Towers and transmits data. But of course it means the SIM card should be stored in a safe spot and not lost.
But we also have a feature that turns Data roaming OFF to help assist with Data Roaming charges.
When abroad, turning off Data Roaming may avoid roaming charges when using email, web browsing, and other data services.
By default it is off. But to check. Go to Settings- General- Network and on the bottom is Data Roaming which should be off.
You can also consult AT&T and see if they got a cheap international data coverage plan you can be put on for the time you will be in Mexico.
I am sure our posters here can advise other ideas as well. Have a great vacation

Some questions about data traffic

Hi Guys,
I live in Kong Kong and have an iphone 3g at the latest version 2.2. I am on a 3 HK plan and all is well when I am in Hong Kong. My work pays for all my phone costs and up until now there has not been any issues. The problem is that I travel a lot with my work to many countries in Asia and some in Europe and when I am there, most times I wait until I have access to a wireless network to get my emails, or as I always carry with me an airport express, I wait until I am in the hotel room and set up my wireless network and away I go. The problem is sometimes I need to get my emails and so I turn on data roaming and download my emails. I have the account set to manual pull and so I can monitor the data that I donwload. The current problem is that the IT department has flagged my increased costs when roaming compared to my colleagues who roam with a blackberry and in some cases it is 10 times the cost. For example, for 3 days in China last month, my bill was about 1000HKd which equates to about 10MB of data. My colleague who was there at the same time with a blackberry who would have a similar amount of emails had a cost of about 90HKd which equates to about 900b of data.
I decided to check today and so reset my data usage monitor and downloaded 9 emails of normal size, no pictures just text and it came to 406KB. Surely this cannot be correct. If it is, and this is my question, is there anywhere that I can limit the amount of data that is downloaded for each email and is there anywhere I can set the emails downloaded for work to be text only and not HTML. My work email is syncing using activesync with my work exchange server.
If I cannot find a way to overcome this, I will either have to stop using data roaming when I am abroad or I will have to take back my blackberry and start using it again which is not what I want at all.
I love the iPhone and actually my IT Manager does not want me to have to use the blackberry and cannot believe it is so data intensive.
Any help from you fellow iPhone lovers would be much appreciated.
Thanks,
Paul

I don't know about your question 1 and 2. Seems like it could be a workout that wasn't ended or just a glitch.
What was your goal? It will measure whatever you set it to measure. Calories burned, distance, run more often, etc.
I set a run more often goal of at least 3 times in 16 weeks. It is averaging and making a calculated guess from that average as to when those runs would take place. So if I run three days in a row and not again that week, I will be ahead of my goal, and then the system catches up and I'm on target again.
I imagine it's doing the same for your goal.

Question about Dates in Project View

I usually have no problems when it comes to date metadata, changing dates if need be, batch changes, etc... But this is something that is confusing me and I haven't been able to solve it.
My wife found one of her old PAS digital cameras, and it had images on the card. I decided to import them for her into Aperture, but it was immediately apparent to me that the date and times were off. The time zone was fine, so I imported the images using a card reader, adding the appropriate metadata of my choosing. After importing the images, I proceeded to change the date and time to the correct dates and times. This worked fine as well, only in Project view, the project doesn't fall into the right place. I have my projects organized into folders, and have them set to Date - Oldest First. The photos from this import show as today's date when I scroll over the image preview box and the project is organized as the last project, which is consistent with that date. The metadata shows that the file date is the date that I set it to be (which in this case would make it the oldest project in the folder). Nothing I do changes anything.
I then decided that maybe it had something to do with importing the images via a card reader instead of off of the Camera directly, so I decided to import straight from the camera. This time, the project is organized as the oldest project, but when I scroll over the Project preview box, the date that shows up is the original incorrect date, not the new date that I changed the photos to. The new date would still make the images the oldest project.
I really just want the dates to match up, and I can't imagine why the Projects preview is showing me one date when the metadata (and my own knowledge of the situation) is telling me that it should be showing a different date. When I made the adjustments to the date and time, I also applied the changes to the Master file.
Does anyone know what is going on here, why Aperture has a problem with something like this and if there is anyway to fix the problem?
Much obliged,
Mac

Update:
I just solved the issue, but I don't know why it should work like this, nor why this should happen.
Basically, the first time that I imported the images, I imported them separately as groups of photos so that I could import them each into individual new projects. I noticed that the first project I created had the right information both in the metadata and in the project pane. This being the case, I decided to import everything again, only this time I imported everything at the same time into one project and called the project, "Test" (this is arbitrary and has nothing to do with the solution).
Next I batch changed the date and time of all of the images in this "Test" project. Once that was done, I separated the images out into their own projects. This time everything showed up and was organized correctly.
Again, I don't know why it had to be done this way, but apparently once I imported the first time, that was the only time that the metadata was accurately recorded. The subsequent imports off of the same card were not recorded properly. Again, I have no idea why, nor what to do about that, but my data is correct now and this seems to have solved the issue.
If anyone has anything to say about the topic, please chime in.
Thanks,
Mac

General question about data recovery from raid on windows server !

hi,
I like to buy data recovery software for windows server to recover data with any raid( or whitout raid
so the company tells me you should be sure the Raid can be recognized correctly as local disk drive first, otherwise, our product wil not help you. so if I want to recover data of my customers which has windows server with any raid form ,how
I can make this server harddisks(which is raid 1,5,6 ect)recognized coorectly as local disk drive.

so I found some data recovery softwares
1-stellarphoenix data recover,which has remote acces and netwerk acces.
2--ease use data recovery software. I liked this second software,but they telling me like this,
you should be sure the Raid can be recognized correctly as local disk drive first, otherwise, our product wil not help you.
I understand the both situations you telling me.thanks
but my question is can I not run data recovery software from bootable usb stick on the smal servers like essential with raid to recover data in case of any problems that caused data loose.
I know if I install data recovery software on the server to scan it ,it wil rewrite some places on harddisk and that is not wise.

There are several ways to accomplish what you want.
KGCW has talked about the Crop Effect.
Depending on exactly where the object is, and whether the camera was locked down, it might be possible to duplicate your Clip, place it above your initial Clip, then offset it a bit (Motion>Position), with the Fixed Effect>Motion>Position, and then apply the Garbage Matte to that offset duplicate, effectively Cropping out everything, but a small "patch" from the existing background. Note: if the edges of that Garbage Matte are too hard for you, you could create a soft-edged Track Matte, and use that to hold out the rest of the offset duplicate.
Another method, and depending on where, and how large the offending item is, would be to go to the Fixed Effect>Motion, and use Motion>Scale to increase the size of the Clip (do not do too much Scale, or quality will suffer). You might also need to do a bit of Motion>Position, to get that red object behind the Video's Frame Size. This will effectively Crop the object.
Good luck,

ICR Process 003 - question about data selection (table FBICRC003A)

Hello, I am implementing ICR process 003. We are doing several test and we I have some questions that I hope you can help me:
1 - If I run transaction FBICS3 - Customer/Vendor( Select Documents) and then FBICA3 - Customer/Vendor (Document Assignment ) several times (the same selection criteria) will the same documents be selected redundantly and will be stored redundantly in table FBICRC003A? I expected that this will not happen but It seems to happen in my test environment. (?)
2- If I need to delete the data stored in ICR '003' functionality I need to use transaction GCDE. The problem as I am using ledger '0L' for '003' process I cannot "delete data of one ledger" functionality -that allows to set selection data- and I have to "delete the data of an entire data group" that deletes all data stored in FBICRC003A & FBICRC003T tables. Should I set another ledger for '003' process in order to delete data using selection criteria? Is it recommended to not to use '0L' and create a new one?
I have read in reference documentation that "is not necessary to set up a SL", but since all my productive companies are running in the same client that is the ICR cliente I am wondering if could be better to create and set a SL.
Thanks in advance

Hi Ralph,
we have created a RFC in order to get data from client B to client A (where ICR system is placed). The summary is:
I need to import vendors/customer data from Client B that belongs to a certain company code "0001". The company is called "X" in both clients A & B although it only exists as a company code (FI) in Client B and just as a company (and trading partner) in client A.
Client A:
1- have set company "0001" as a "Company to be reconciled" at FBIC032:
RFC destination = ""
RFC destination for data selection = "ZRFC0001"
Local company= ""
Data Source="Documents of Current Process"
Separate Selection Process= "X"
Data Transfer Type="Asynchronous via Direct RFC Connection"
Sender field for reference number = "XBLNR"
Client B:
1- I have created the companies (V_T880) that I will need in order to inform trading partner on vendor's master data.
2- I have assigned company code '0001' to company "X"
3- I have assigned trading partners created on step 1 to vendors
4- I have post few FI documents with trading partners informed.
Then I run FBICS3 - Customer/Vendor: Select Documents in background but the programs takes a lot of time and do not select any document.
Do you think that I am missing something?
Thanks very much in advance.

I have a question about data aqusition from PCI bus

Hi.
I am designing a PCI card.I wonder if I want to do some process in LabVIEW,such as power spectrum analyse, oscilloscope, do I have to transfer the data continuously from my card?
Thank you.

Simple answer - no.
More complex answer - LabVIEW is just like any other programming
language when it comes to data collection frequency. The
frequency (intermittent, continuous, timed, etc.) depends upon the
analysis you are attempting. To do power spectra or display
waveforms, all you need is one set of data at a time. The data
does not have to be continuous. There are classes of problems
which require continuous data. If you are trying to address them,
you will need to have this mode of operation available. Most NI
input boards offer both modes - continuous and intermittent, with
intermittent being the most used, by far.
Note that with proper buffering, both modes end up being about the
same. Whether your buffer resides on the card (preferred, is more
robust, data transfer timing is not so critical) or in the computer
main RAM, the LabVIEW side of things will always take a single set of
data at once. Admittedly, this data set can be one point at a
time, but you really don't want the overhead of that in LabVIEW (or any
other higher level function - should be in your driver).

General question about dates

I'm starting to scan my old slides and negatives and am scratching my head about "fuzzy" dates. Sometimes it's not clear when a photo was taken, so either a date range, such as 9-12/1970 is used, or maybe something like Early/1970. How does one handle that situation in pse?

I maintain a library of historical and family photographs and I have struggled with this challenge for years. I finally have a solution. I use IDImager, a digital asset management application used mainly by professional photographers. It has (parametric) editing capability and some users (like myself) are able to use it exclusively for their digital photo needs. Others use it in combination with apps like Lightroom, Photoshop, PS Elements.
It (http://www.idimager.com) does not natively address the fuzzy (unknown or partially known) date problem, but does allow the end user to create and manage custom XMP fields which opens the door to make this problem solvable to the end user. IDImager is written in Delphi and allows user-created scripts to run within IDImager. Users can submit scripts to the IDImager Resource Repository to share their scripts with other users.
I have submitted a collection of scripts and custom XMP definitions to the repository called "HouseOfUlrich toolset for unknown and partial dates". It is a collection of custom XMP fields and scripts that make it easy to tag and manage photos with "fuzzy" dates within the existing framework of IDI without a major disruption to the workflow. Meaning... it doesn't take much longer(if any) to assign a "partial" date to a photo than to assign an exact one and images are still sortable and searchable without being treated separately from photos will fully known date/times.
You can download the toolset free from: http://repository.idimager.com/cgi-bin/idi_script_repository.exe?action=scriptDetails&scri ptID=567594c9-1b90-4f94-4641-4fccb60dc8ea and read the readme file for all the details. But to summarize, the toolset, without modification supports
1) a boolean value to indicate the date is unknown/partial (use this unless the FULL date and time is known)
2) a boolean value to indicate the date is approximate
3) fields to store year, month, day (and these fields DO support ## - special character to indicate unknown).
4) scripts that can "convert" traditional EXIF date/time fields to the Custom XMP fields, leaving the original EXIF unchanged, of course.
IDImager allows for custom XMP to be used in rename functions, so I can employ the custom XMP fields I use to automatically create/change filenames to create naming conventions like:
[email protected] (to indicate photo taken at 11:23:23 PM on March 3, 2007)
1910-05-##@##-##-##_circa.jpg (to indicate a photo taken ABOUT May of 1910.)
192#-12-25@##-##-##.jpg (to indicate a photo taken on Dec 25 sometime in the 1920s.)
I have chosen to implement using the "approximate" value in combination with months to indicate times of year. For example, for photos in summer of 1935, I would use Circa (approx value) 07 1935. But both IDImager and my toolset are open-ended and would allow for users to define and use alternate XMP fields like Early,Mid,Late or Spring,Summer,Fall,Winter. I choose the numeric values corresponding to months and the "approximate" value because they are more easily lent to other scripting and sorting functions within both IDImager and the operating system.
Something else that could be implemented, although I have chosen against, is the use of a "date range" using one field for "as early as" and another for "as late as". I see this method as more trouble than its worth as it would not lend well to sorting, name, searching etc. I think the ability to set year,month,day all to either known/unknown in combination with defining the entire date as approximate is better. For rare cases where one wanted to store the fact that a photo was taken as early as/as late as....I would recommend just storing that info as a string in the description field. For example, I have photos taken of soldier's during WWI. If it is not possible to determine whether late or early in the war, I would tag it as Circa 1916 (or 1910s). But could still use the description field to write "taken during WWI (probably 1914 - 1918)".
One other final note: If Adobe or some other player in the digital photo market does ever create an updated XMP or EXIF schema that support unknown or partially known dates, it will be possible, with IDImager, to migrate the information I store in custom XMP fields to the new standard fields.
hope these resources help other solve the same challenges I finally overcame. happy tagging.

Few questions about data

I was on a unlimited data plan was just recently put on a shared plan 2gb limit.
Here was I need to know - when your talking on the phone, does that use data? when you text someone, does that use data? using GPS ,does that use data? Instead of internet and Facebook, what else use's up data? I am using wyfi at home. But when I check data use for the previous day it using data.

Texting and minutes do not count against data. That's why you have minute plans and texting plans. GPS itself doesn't use data but any mapping service like Google Maps will uses data to download the maps. Make sure you disable auto-updating on apps. And have apps only update over wi-fi. Also you can turn off background data. If an app needs you can turn it on then. You also make sure you have things like e-mail and any cloud storage only works on wi-fi and do not auto download/upload. You can also make sure wi-fi automatically turns on if you start and app and wi-fi is present. Any places I go frequently that have free wi-fi I make sure I save in my Available Networks so I can automatically connect to them when I go there if I decide to use my phone.
In the last year with my 2 GB pan the most I've used in a month is 1.1 GB and most months I'm under 500 MB.
