Efficient Time effective algorithm to read a BIG Size Image matrix
Hi,
I am given a specific problem for Big size Matrix data handling.
In a File there are Huze data in the Matrix form (m*n) - These data basically represents some image pixel value.
say for example I am give a pixel value of leena image of size 5MB.
What should be the efficient logic for faster reading of the File and put it in a Data Structure,
What should be the efficient Data structute to hold that huge data (data range varry from 0-255)
Thank you

It rather depends what you want to do with the data. For most purposes, I'd imagine that that the standard image libraries are pretty good.

I get succede to work with the below link to upload the image.
But its not working for the big size image. Could you please help any one.
http://search.experts-exchange.com/simpleSearch.jsp?q=upload+OR+imag+OR+servlet+OR+java+OR+asp+OR+upload+OR+imag&searchSubmit=trueBig images could take a lot of memory. For instance 3000x3000 ARGB image will take 34MB in memory. If you load 2 images in memory then it takes more than 64MB that could be a problem with default Java Heap size (64MB). A solution is to not load the image fully in memory to display. Try the following image upload applet with large image: http://www.jfileupload.com/products/jimageupload/index.html and you will see if it helps.

How planned delivery time effects delivery creation?
Dear All,
Some time before, while placing order thro' CRM, we came across a typical error (hard error).
"date (11/12/2011) lies afterthe end of validity calendar".
we could not place order in CRM but in SAP we could create save the order despite of same error but soft. However system didn't allow to create delivery for same order & same error message populated"
Later it was found that it is because for material " Planned Deliv. Time maintained for say "X "days in material master MRP2 view" & was corrected.
How planned delivery time effects delivery creation?
For material even though planned delivery time was maintained as say for 500 days, sales order requested delivery date & delivery date in order schedule line got determined as order date (Considering avaliability of funds & material).
i.e order date/req. delivery date/delivery date in schedule line are same as date on which order is placed.

The Time Machine is not completing thte backup to my Time Capsule. I am receiving a message which reads "The backup disk image "/Volumes/Data/Mac Jet's iMAC.sparsebundle" is already in use." I cannot locate the source of the problem or what steps need to be taken to get the Time Capsule operating.
Hi, see if it shows here...
In Finder's Menu, select Go menu>Go to Folder, and go to "/volumes". (no quotes)
Volumes is where an alias to your hard drive ("/" at boot) is placed at startup, and where all the "mount points" for auxiliary drives are created for you to access them. This folder is normally hidden from view.
Drives with an extra 1 on the end have a side-effect of mounting a drive with the same name as the system already think exists. Try trashing the duplicates with a 1 or 2 if there are no real files in them, and reboot.
If it does contain data...

Time effect problem with adjusment layer
Hi,
I made an adjustment layer above two footages. Everything is working (color, levels etc.) with that except time effects. When I drag twixtor to it the video turns to red. The original picture:
The twixtored one:
And when I use timewarp effect this happens:
The lower side has crapped out and even my black and white color has been removed. Is it because of the size or fps or what else?
(720p footages, 50 fps, I changed comp size, version is AE CS6 11.0.0.378)Pre-compose or render the comp that you want to speed up or slow down. Add a solid. Apply Twixtor to the solid. Use the pre-comp as the source and make the time changes you are planning.

SAP HANA One and Predictive Analysis Desktop - Time Series Algorithms
I have been working on a Proof-of-Concept project linking the SAP Predictive Analysis Desktop application to the SAP HANA One environment.
I have modeled that data using SAP HANA Studio -- created Analytic views, Hierarchies, etc. -- following the HANA Academy videos. This has worked very well in order to perform the historical analysis and reporting through the Desktop Application.
However, I cannot get the Predictive Analysis algorithms -- specifically the Time Series algorithms -- to work appropriately using the Desktop tool. It always errors out and points to the IndexTrace for more information, but it is difficult to pinpoint the exact cause of the issue. The HANA Academy only has videos on Time Series Algorithms using SQL statements which will not work for my user community since they will have to constantly tweak the data and algorithm configuration.
In my experience so far with Predictive Analysis desktop and the Predictive Algorithms, there is a drastic difference between working with Local .CSV / Excel files and connecting to a HANA instance. The configuration options for using the Time Series Algorithms are different depending upon the data source, which seems to be causing the issue. For instance, when working with a local file, the Triple Exponential Smoothing configuration allows for the specification of which Date field to use for the calculation. Once the data source is switched to HANA, it no longer allows for the Date field to be specified. Using the exact same data set, the Algorithm using the local file works but the HANA one fails.
From my research thus far, everyone seems to be using PA for local files or running the Predictive Algorithms directly in HANA using SQL. I can not find much of anything useful related to combing PA Desktop to HANA.
Does anyone have any experience utilizing the Time Series Algorithms in PA Desktop with a HANA instance? Is there any documentation of how to structure the data in HANA so that it can be properly utilized in PA desktop?
HANA Info:
HANA One Version: Rev 52.1
HANA Version: 1.00.66.382664
Predictive Analysis Desktop Info:
Version: 1.0.11
Build: 708
Thanks in advance --
BrianHi,
If you use CSV or XLS data source you will be using Native Algorithm or R
Algorithm in SAP Predictive Analysis.
When you connect HANA, SAP Predictive Analysis uses PAL Algorithm which runs
on HANA server.
Coming to your question regarding difference,
In SAP PA Native Algorithm, we could provide the Data variable, Algorithm
picks the seasonal information from the Data column. Both R and SAP HANA PAL
does not support Date Column. We need configure seasonal information in
Algorithm properties.
R Properties
1) Period : you need to mention the periodicity of the Data
Monthly : (12)
Quarter : (4)
Custom : you can use it for week or Daily or hourly.
2) Start Year: need to mention Start year.
Start year is not used by algorithm for calculating Time series, but it helps
PA to generate Visualization ( Time series chart) by simulating year and
periodicity information.
3) Starting Period:
if your data is Quarterly and you have data recordings from Q2, mention 2 in
start period.
Example.
If the data periodicity is Monthy and my data starts from Feb 1979, we need to provide following information,
Period: 12
Start year: 1979
start Period: 2
PAL Properties. : Same as properties defined in R.
Thanks

I asked if AVCHD files can be played on Mac and the support site says to simply click on the icon and quick time will play it. A big lie. Just say it won't support the file type and tell us what apps to get. anybody?
I also had issues opening AVCHD files on case-sensitive filesystems.
You can try these steps to solve the issue:
Right click on the AVCHD file and select 'Show Package Contents'
Right click on the BDMV file and select 'Show Package Contents'
Rename index.bdm to INDEX.BDM (it seems that all files in the BDMV folder should be in UPPERCASE for Quicktime to open the AVCHD file).
Go back twice and try again to double-click on the AVCHD file (Quicktime should open a window showing the multiple clips, as expected). -

I recently upgraded from CS6 to Creative Cloud.
The CC Wide Time effect which I use a lot is still listed in the filters, but when I try to apply it to a composition it tells me:
after effects error (517) this version of cc wide time is only for use with after effects cs6
Any ideas?
ThanksUntil bug fixed, I decided to use CC Wide TImes on AE cs6 for certain clips
Well, effect loaded, but dones not work properly on cs6 now.
cs6 is also updated, latest version...is it alos bug ?
say
On Windows 7,
AE CS6 CC Wide TIme can load, effect does not work...
AE CC error message..
on OSX CC just works fine.
I want to avoid converting huge files to Mac and back to PC.
How soon can you fix this bug ?
I really appriciate if you can let us know..
Thank you. -
I have my time machine set-up with my time capsule/airport. I cannot open my backups in the time capsule as it reads "spars bundle temporarily unavailable." Also, my time machine backup files are missing some files and not in oder by name as designed. It seems something is is not working. I have don a disk repair on the time capsule. I have closed and reopened my computer. Still unable to open time capsule. Does anyone know where else I need to check for errors?
There are two key but related bugs in Yosemite..
The big one IMHO at least is the network one.. and the secondary one is TM which is itself unreliable.
To fix the Network ones we have a long list of things to do.. but you do apparently have access to the TC so for now that is not the major one.
However some of your statements mean I am a bit lost on what you have done.
I cannot open my backups in the time capsule as it reads "spars bundle temporarily unavailable."
If you cannot open your backups how can you find that the backup files are missing. The files are missing from the sparsebundle which you cannot open??
my time machine backup files are missing some files
You cannot repair the disk of the Time Capsule.. only the Sparsebundle can be checked.. that means that you have accessed it and mounted it for disk utility to check it.
I have don a disk repair on the time capsule.
So I am confused about the comments.
What I would recommend is the standard set of fixes to Yosemite.
Factory reset universal
Power off the TC.. ie pull the power cord or power off at the wall.. wait 10sec.. hold in the reset button.. be gentle.. power on again still holding in reset.. and keep holding it in for another 10sec. You may need some help as it is hard to both hold in reset and apply power. It will show success by rapidly blinking the front led. Release the reset.. and wait a couple of min for the TC to reset and come back with factory settings. If the front LED doesn’t blink rapidly you missed it and simply try again. The reset is fairly fragile in these.. press it so you feel it just click and no more.. I have seen people bend the lever or even break it. I use a toothpick as tool.
N.B. None of your files on the hard disk of the TC are deleted.. this simply clears out the router settings of the TC.
Setup the TC again.
ie Start from a factory reset. No files are lost on the hard disk doing this.
Then redo the setup from the computer with Yosemite.
1. Use very short names.. NOT APPLE RECOMMENDED names. No spaces and pure alphanumerics.
eg TCgen5 and TCwifi for basestation and wireless respectively.
Even better if the issue is more wireless use TC24ghz and TC5ghz with fixed channels as this also seems to help stop the nonsense. But this can be tried in the second round.
2. Use all passwords that also comply but can be a bit longer. ie 8-20 characters mixed case and numbers.. no non-alphanumerics.
3. Ensure the TC always takes the same IP address.. you will need to do this on the main router using dhcp reservation.. or a bit more complex setup using static IP in the TC. But this is important.. having IP drift all over the place when Yosemite cannot remember its own name for 5 min after a reboot makes for poor networking. If the TC is main router it will not be an issue.
4. Check your share name on the computer is not changing.. make sure it also complies with the above.. short no spaces and pure alphanumeric.. but this change will mess up your TM backup.. so be prepared to do a new full backup. Sorry.. keep this one for second round if you want to avoid a new backup.
5. Mount the TC disk in the computer manually.
In Finder, Go, Connect to server from the top menu,
Type in SMB://192.168.0.254 (or whatever the TC ip is which you have now made static. As a router by default it is 10.0.1.1 and I encourage people to stick with that unless you know what you are doing).
You can use name.. SMB://TCgen5.local where you replace TCgen5 with your TC name.. local is the default domain of the TC and doesn't change.
However names are not so easy as IP address.. nor as reliable. At least not in Yosemite they aren't. The domain can also be an issue if you are not plugged or wireless directly to the TC.
6. Make sure IPv6 is set to link-local only in the computer. For example wireless open the network preferences, wireless and advanced / TCP/IP.. and fix the IPv6. to link-local only.
There is a lot more jiggery pokery you can try but the above is a good start.. if you find it still unreliable.. don't be surprised.
You might need to do some more work on the laptop itself. eg Reset the PRAM.. has helped some people. Clean install of the OS is also helpful if you upgrade installed.
Tell us how you go.
Someone posted a solution.. See this thread.

Yosemite has serious DNS bug in the networking application.. here is the lets say more arcane method of fixing it by doing a network transplant from mavericks.
http://arstechnica.com/apple/2015/01/why-dns-in-os-x-10-10-is-broken-and-what-yo u-can-do-to-fix-it/
That is all to cover the network side of things.
Time Machine issue is a harder one because there is no simple work around I can give you.
My recommendations are to stop using a TC and test TM to an external hard disk plugged into the computer.. Do a whole new backup and see if that is fully working and accessible.
Or change over to third party program for backup.. I do recommend Carbon Copy Cloner as I use it personally but SuperDuper has a good reputation and there are others. It is far easier and quicker to test a bootable clone made with CCC as you simply boot from the backup. -
Although Logic's time-stretch algorithm's have come on a long way over the years, they're still no match for 3rd party equivalents.
I've been very impressed with Serato's Pitch n Time, & Melodyne, but wondered if I've over-looked any others? Any opinions on the most transparent time-stretch algorithm or software out there? (Primarily for monophonic sources - mainly vocals).Aside from the ones you've mentioned I'm not sure there is much else thats comparable - except Pro Tools but thats a different kettle of fish.
I think aside from DNA in Melodyne, they improved the general monophonic algorithm in the new version and it's much better than it was. -
when I bought my D800, lightroom would not read my big NEF files .. I went crazy…. so I found out I had to transform them into DNG .. should I keep the DNG or the NEF files? Now, I tried again and I am being able to work with the NEF files … don't understand…. anyway … I have to throw away some files … they are to big … should I throw the NEF or the DNGs? (as the DNGs are not edited yet…)
Hard to say why you couldn't open them first time around...possibly low memory?
In any event, as to the question about which to keep. This is a topic that is argued long and hard here and in other forums.
For myself, I use only the NEF files and don't bother with DNG at all. Just can't see any long term advantage to force me to do all that extra work. Others feel that the "universal" format of DNG make it worthwhile.
Either way, it's hard to justify keeping both (though a few people do).
good luck

Could anyone tell me what to do to solve the problem. I updated FCPX to 10.9 and the program keeps on crash every time I try to read files stored in my LaCie hard drive. And the program also keeps on crash every time I try to import files from my SDXC cards.
I have solved the problem. Once the update is done, you need to launch FCPX, and go to File, then "update all events and projects". It will solve the problem and everything works fine.

At first Thunderbird downloaded every email from the problem account going back to 2011. I changed the server settings to only download emails from the last 15 days and to delete any messages older than 15 days.
I can send emails from this account and my other email account works fine for sending and reading mail. However, this problem account crashes Thunderbird every time I try to read the messages. There are now only 300 messages in the inbox and I've been able to have them marked as read. But I still can't read any of them.

Hi,
problem-In Time Series Algorithm predication is wrong if Sales value is negative
i have data for more than 3 years ,
sample data like
Year/Month
Zone-1 Sales

Due to negative value my prediction for next month is wrong. Please tell me how I can handle this problem. Negative values come due to sales return in zone.Hi Leo,
Thanks a lot for replay.
but using help of this blog also this problem not solve.
is this problem can we solve using "Seasonal Decomposition of Time Series by Loess".
