Measuring both Area and Perimeter

Hi gentleman,
I tried to measure area and perimeter at the same time but couldnt find a way to do that. I need to cover an area and to see area and perimeter at the same time and drawing two seperate measure lines -one for area the other for perimeter, is gonna be quite time consuming for me. Is there a way to see area and perimeter at one shot? I am using Adobe Acrobat 8 Professional.
thx for your help

one thing to not bout this before a bunch of formula go flying around:
sometime people foolishly think that there are 360 degrees in a circle, but they are wrong there is really 2*PI radians :)
For a Sector of a Circle of Radius 'r'
Area = 0.5 * r * r * a - a is the angle in radians
Arc Length = r * a
Perimiter = Arc Length + 2 * r
here is the trick if you are told that the angle is 10% of a circle then
a = 2 * Math.PI() * (10/100)
if you are told it is 45 degrees
a = 45 / 360 * 2 * Math.PI()
that should help a bit

Coverage area and perimeter

Hello,
I don´t understand very well the difference between coverage area and perimeter in the WCS Map Editor.
I only want that APs coverage offer service inside the building and then avoid that a person can connects when he is outside the building.
To do it, What I have to do? I have to draw a coverage area inside the building or perimeter, or both?
Regards,

Hi, thx for your reply. I played with the Planner, defining one large Perimeter and 4 Coverage Areas inside, excluding one Inner Area. The Planner dont worry about that, he plans for the full Area. Regards, Michael

Area and Perimeter of Slice of Pie

I have a class assignment to figure both the perimeter and area of a Circle, rectangle and a slice of pie based on user input. I have the circle and the rectangle working correctly, however I am having trouble with the slice of pie. I have to prompt the user for the degrees of the slice of pie and the radius of the slice of pie and some how figure out the perimeter and area. Thanks in advance for any help!

How can the ruler and or the measurement tool calibrated? both are totally off.

Earlier, I wrote:
What is the ppi value in the document? Use the Image - Image Size menu to see or set this value.
I can't believe this conversation has gone on this long. You keep wanting it to be a bug, but it seems to me the basic problem here is that you haven't accepted the fact that YOU are responsible for getting the image metadata in order before you can use tools like the Ruler to read out in physical units, such as inches or centimeters, accurately.
Photoshop can only know the size of things in your document if you or your workflow provide it an accurate ppi value!
What's the original source of the material? A scanner? If so, some part of the scanning or image preparation process has left you with an inaccurate ppi value.
For the documents you're already working with, use Image - Image Size, then UNcheck the Resample Image checkbox and type in the correct ppi value. Then everything will work.

What is difference between sy-index and sy-tabix and where both are using ?

what is difference between sy-index and sy-tabix and where both are using ?

hi nagaraju
sy-tabix is in Internal table, current line index. So it can only be used while looping at the internal table.
sy-index is in Loops, number of current pass. This you can use in other loop statements also (like do-enddo loop, while-endwhile)
SY-INDEX is a counter for following loops: do...enddo, while..endwhile
SY-TABIX is a counter for LOOP...ENDLOOP, READ TABLE...
Here is an example from which you can understand the difference between sy-tabix and sy-index.
Itab is an internal table with the following data in it.
id Name
198 XYZ
475 ABC
545 PQR.
loop at itab where id > 300.
write :/ itab-id, itab-name , sy-tabix, sy-index.
endloop.
My output will be :
475 ABC 2 1
545 PQR 3 2
Sy-tabix is the index of the record in internal table.
sy-index gives the no of times of loop passes.
So, for the first record in the output (475 ABC), 2 is the index of the record in internal table and as it is first time loop pass occured, sy-index value is 1.

HT3819 how do I share movies/music between my computers. I have opened shared on both computers and both are on, but i am not able to drag anything from one to the other. Does anyone know where the settings button is on the bottom of the itunes screen?

Oops, I forgot a step between 7 and 8 ... before syncing the iPhone I need to explicitly send the document back to iTunes on the iPhone, or the changes won't come over at all ...
and then one more thing ... Numbers on iOS does NOT recognize a number of key features of the OSX app, such as conditional formatting ... so after editing my document on iOS and syncing it back to OSX on my Mac, all of those settings are lost (no more conditional formatting, have to do it all over again)
What am I doing wrong ?

I am trying to read my iMessages from my iPhone 4S on my iPad 2, but the messages do not show up on my iPad 2. I made sure that the receiving email address is the same on both devices and both are signed into my single Apple account.

Is it possible that the person who sent the message to your phone sent it to your phone # instead? Try sending a message to your phone via the email address and see if it shows up on the iPad.

What model iPad do you have? If it's an iPad 1, the battery may have expired and needs replacement.

My ipad receives email with the hotel wifi but will not send. The error message is "user name or password for ........is incorrect" but both are correct and unchanged. Restarting iPad didnt help.

My iPad receives email on the hotel wifi but will not send. The error message reads "user name or password for smpt......is incorrect" but both are correct and unchanged. Restarting iPad did not help.

I did try this too, but when I access my webmail on the iPad, the iPad doesn't allow me to type my message. I am able to enter in the "to" address and the "subject" line, but then the keyboard will not come up for me to type my message. Is there some trick to this? Very frustrating!

Every time I ask Siri to find something near me, she says that she cannot find my location, and to turn on my location settings and siri settings. These are both on and after rebooting it still doesn't work. How do I fix this?

No, the app does not have to completely restart. It gets shifted in its open state into storage. Similar to how a computer uses the hard disk when it has insufficient memory.
What complicates things is that sometimes memory does not get returned for reuse when you close an app. Thus yo should periodically double click the Home button and "delete" unnecessary apps from the multitasking dock and power off and then back on the iPod.

I am having the same problem with brand new Ipad Mini at my house.
It connects to the WiFi fine - but will not pull an IP address in DHCP mode, or if I set all the IP info statically - it still will not get any network access.
This doesn't look like a WiFi issue, as it does connect and is seen by the WiFi Access Point. All the normal WiFi fix stuff doesn't help.
- Using a Dlink DAP-2553 which is less than 2 months old.
Other devices connect fine, including Ipad 2.
This same Mini worked fine at another house and also connected to a mobile hotspot fine....so seems to be some weird IP issue with maybe this Access Point or maybe the older Router that I have (older Netgear)?
I am actually a network engineer and still have not been able to find a solution. Both the Ipad Mini and the Dlink WAP have the latest firmware loaded.
Wondering if anyone has found a solution to this problem.

I am in the process of expanding a database of chemistry journal articles. These materials are ideally acquired in two formats when both are available-- PDF and HTML. To oversimplify, PDFs are for the user to read, and derivatives of the HTML versions are for the computer to read. Both formats are, of course, readily recognized and indexed by Spotlight. Journal articles have two essential components with regards to a database: the topical content of the article itself, and the cited references to other scientific literature. While a PDF merely lists these references, the HTML version has, in addition, links to the cited items. Each link URL contains the digital object identifier (doi) for the item it points to. A doi is a unique string that points to one and only one object, and can be quite useful if rendered in a manner that enables indexing by Spotlight. Embedded URL's are, of course, ignored by Spotlight. As a result, HTML-formatted articles must be processed so that URL's are openly displayed as readable text before Spotlight will recognize them. Conversion to DOC format using MS Word, followed by conversion to RTF using Text Edit accomplishes this, but is quite labor intensive.
In the last few months, I have added about 3,500 articles to this collection, which means that any procedure for rendering URL's must be automated and able to process large batches of documents with minimal user oversight. This procedure needs to generate a separate file for each HTML document processed. Trials using Automator's "Get Specified Finder Items" and "Get Selected Finder Items", as well as "Ask For Finder Items" (along with "Get URLs From Web Pages") give unsatisfactory results. When provided with multiple input documents, these three commands generate output in which the URLs from multiple input items are merged into a single block, which yields a single file using "Create New Word Document" as the subsequent step. A one-to-one, input file to output file result can be obtained by processing one file at a time, but this requires manual selection of each item and one-at-a-time processing. What I need is a command that accepts multiple input documents, but processes them one at a time, generating a separate output for each file processed. Is there a way for Automator to do this?

Hi,
With the project all done, i'm preparing for the presentation. Managed to get my hands on a HD beamer for the night (Epason TW2000) and planning to do the presentation in HD.
That of course managed to bring up some problems. I posted a thread which i'll repost here . Sorry for the repost, i normally do not intend to do this, but since this thread is actually about the same thing, i'd like to ask the same question to you. The end version is in AfterEffects, but that actually doesn't alter the question. It's about export:
"I want to export my AE project of approx 30 min containing several HD files to a Blu Ray disc. The end goal is to project the video in HD quality using the Epson EMP-TW2000 projector. This projector is HD compatible.
To project the video I need to connect the beamer to a computer capable of playing a heavy HD file (1), OR burn the project to a BRD (2) and play it using a BRplayer.
I prefer option 2, so my question is: which would be the preferred export preset?
Project specs:
                    - 1920x1080 sq pix (16:9)
                    - 25 fps
                    - my imported video files (Prem.Pro sequences) are also 25 fps and are Progressive (!)
To export to a BRD compatible format, do i not encounter a big problem: my projectfiles are 25 fps and progressive, and I believe that the only Bluray preset dispaying 1920x1080 with 25 fps requests an INTERLACED video (I viewed the presets found on this forum, this thread)... There is also a Progr. format, BUT then you need 30 fps (29,...).
So, is there one dimension that can be changed without changing the content of the video, and if yes which one (either the interlacing or the fps).
I'm not very familiar with the whole Blu-ray thing, I hope that someone can help me out."
Please give it a look.
Thanks,
Jef

HT3819 Home Share issue: I have a Mac and Apple TV. Both are log into the same Wifi network and the same iTunes account (I can view purchased movies on AppleTV). Home Sharing shows 'ON' for both devices. BUT...AppleTV shows no computers. Itunes sidebar-no

Has anyone else found solution to Apple devices not 'seeing' each other on Home Share? I have a Macbook Air (new Nov'12) and Apple TV (new Dec'12). Software updated on both. Both are logged into the same Wifi network and the same iTunes account (I can view movies purchased from iTunes on my AppleTV). Home Sharing shows 'ON' for both devices. BUT...AppleTV shows no computers... and ... Itunes sidebar does not have a 'Shared' area at all. Help please as without this functionality, my Apple TV only provides portal to purchased (i.e. Netflix,...) content which I can get from Wii or Xbox.
I have already tried the following without success:
1. Homeshare DID work the first day after I setup Apple TV... but the next day it has not worked since then.
2. Powered off 30 sec then re-started (Apple TV & Macbook & iTunes login)
3. Checked Firewall settings per Home Sharing troubleshooting guide (correct settings)
4. Turning on Photostream in iPhoto and selecting iPhoto within iTunes and then checking to see if Photostream shows anything on AppleTV (it shows 'on' for my iTunes account but 'Zero' pictures found ... despite the >3,000 pictures showing avail in iTunes).
I also have 'Remote" app on my iPhone 4, with Home Sharing turned on (same Wifi network)... it has a very similar message as the Apple TV and same result that despite all devices having HomeShare 'on' they cannot see each other: "Remote will automatically find the iTunes libraries and Apple TVs that have Home Sharing turned on using the account xxxx (it lists my correct itunes account name)."

I solved this by reset of the Wifi (unplug cable and power to both modem and wifi ... wait 60 sec ... plug in modem cable and power ... plug in wifi power and LAN to modem ... restart AppleTV and Mac ... Turn Home Share 'OFF' in iTunes then back "ON" ... it took ~60 sec for the AppleTV to pick up my Mac in computers.

I have a jetpack, and when I try to "connect" to my ipad or phone, it keeps telling me I am not using the correct password. I have tried everything. I even changed the password, nothing is working. Both are 4G, my ipad is an Air and my phone is a Iphon

I have a jetpack, and when I try to "connect" to my ipad or phone, it keeps telling me I am not using the correct password. I have tried everything. I even changed the password, nothing is working. Both are 4G, my ipad is an Air and my phone is a Iphone 5. I can get connected to other wifi on these features but not with my jetpack. Please help, I need to use this feature soon. Thank you so much

Chances are you mis-typed a character in the Wifi password and the devices saved that information. Now whenever you try to connect the device refers to the wrong password and the Jetpack does not accept your connection. Tell your devices to forget the wireless connection and start over.
Once you enter the proper WiFi credentials the Jetpack will allow you to connect.
