How does Calendar calculate travel times?

When I select the Travel Time function for an event in Calendar, it tells me there is a 35 minute travel time from home to my scheduled event destination. However, when I transfer over to the Maps application to get the directions from my home, the Maps application tells me the travel time is 52 minutes, which is more accurate. I have no previous events on my calendar that the application could use as a reference point, and the time of the event is outside of the working hours I setup in Calendar, so it is not using my work location as a reference point. What can explain the travel time discrepancy between Calendar and Maps?

If I understand the feature correctly, this is not an Exchange supported function. Therefore, you won't be able to use this option for Exchange. iCloud Cal supports it. Interestingly, i too have both calendars and use exchange almost entirely as well - when I change to entering an exchange appt, the travel time option disappears totally. It sounds like you have the options still available.
Sorry, no answer to your problem here but maybe this adds another piece of the puzzle.

How does xMII calculate a time weighted average?

I am in the process of doing data validation for tag query result sets from IP21 process data. The comparison is against an IP21 add in to Excel which generates numbers that don't correspond to the numbers generated by xMII. The add in appears to be generating values according to a Time Weighted Average but it is returning different numbers. The differences are not large, but it is a virtual certainty that a plant manager or process engineer will take issue. So we (I and my client) would like to know how to explain the difference in the calculation results. We suspect that it involves interpolation for missing data, but would like to know for sure. We are also checking the IP21 algorithm(s) to make sure we understand how it works. Any insight would be appreciated.

Rick/Jeremy,
I am still not getting the same values. My correlation testing is in Excel 2003. In xMII I have the number format set to 0.000000. Typical values in the result set are coming in with five decimal place accuracy. I am using one hour's data at 1 minute intervals with date accuracy to the second and the data is compressed to 52 actual datapoints. The time range is 11/07/2007 00:00:00 to 11/07/2007 01:00:00. It is in HistoryEvent mode. The row count is set to 20000.
When I run the TWA from xMII, I get 22773.576740.
When I ran my first algorithm in Excel, I get 22767.37321. When I made the change to what Rick said, I get closer but am still off and get 22769.35835. Can either of you (or anyone else) explain the delta? I have rerun both calculations twice on all three sides and get the same results.
Here is my data:

How do I sync travel time from iCal to calendar on an iOS device?

Hi, I really like the feature travel time in iCal. Unfortunale it only works great on the Mac. Therefor I only get the correct time when to leave when I am at home.
I have an example:
I made an apointment that is 2 hours and 3 minutes travel time away on my iMac. This is actually transferred to my iPhone correctly.
I also added an apointment with a lication in the same city. On the iMac it shows me that I will need 8 minutes from the first meeting to the second apointment and that it will remind me in time to leave. Everything seems fine. But when I look in calendar on my iPhone it will remind me 1 hour and 8 minutes before the meeting starts. That does not make any sense.
I thought that maybe iOS calendar adds the usual time set to remind me and adds the driving time. This is not the case since the usuall time is set to two hours. On the iMac the usuall time to remember me is set to one hour. It is probbably coming from here that it adds the hour but it does not make sense.
Does anynbody know how to use the travel time funktion properly for all devices?
I am also lokking for a way to set the reminder to travel time plus X minutes. It would make sence to get reminded when to get ready and not when you sit at your desk and are actually supposed to get out of the house...

Ok, I found the answer.
iCal will push the travel time plus the standard reminder time to the iOS device. So I set the standard remeinder to 10 minutes and I know whenever I am reminded that I have 10 minutes to get going. We can only hope that Apple will work some kinks out of this feature and we will be able to set a standard reminder for all appointments with travel time like "Leave in 30 minutes" to finish up what your doing or wrap up a meeting and then "leave in 5 minutes" to really get going. If you have the same issue write to apple.com/feedback. Maybe they will work on it if the get more feedbacks...

Set Start Position to Calculate Travel Time in Calendars

Hi All,
I am quite impressed with the new traveling time feature in Calendars, however I cannot seem to get the best out of it.
Is there a way to reset the start position for the calculations, I am thinking about the following senario;
Three appointments in the same day Appointment one calculates OK but appointment two calculates the start from the office and not the location of appointment one. Same thing happens with appointment three.
What I want to do is set the first appointment, calculate travelling time, set the second and calculate the traveling time from appointment one and then the same with appointment three.
The only way I have found to do this is to jump back and forward between calendar and maps and manually calculate like I used to do before this update.
Thanks in advance for any replies.

This solved my questionRe: Calendar Travel Time Starting from Work when I want to Start from Home Oct 23, 2013 8:43 PM (in response to theglenlivet12)
From Calendar's help:
To set your starting location, Calendar first looks for your location in any events that are up to three hours before this event. If Calendar doesn’t find a location, it uses your work address during work hours and your home address during other hours. (Your work hours are set in Calendar preferences using the “Day starts at” and “Day ends at” menus.) If your card in Contacts doesn’t have your addresses, Calendar uses your computer’s current location.

How do I calculate a time such as work hours

How do I calculate a time such as, a cell may have any time valve pertaining to daily work hours. 8:00 or 7:00 or 10:30. My question is I want another cell to represent any amount over 8:00. Like in a nine hour day you would have 8:00 with 1:00 overtime

This may help:
The first row is a header.
select the three columns and format as "Duration":
now enter the formulas as:
B2=IFERROR(IF(A2>DURATION(0, 0, 8), DURATION(0, 0, 8), DURATION(0, 0, 0)), "")
C2=IFERROR(A2-B2, "")
select B2 and C2, then fill down as needed

How do I switch Travel Time in Mac Calendar from work to home?

I recently installed Mavericks and have been using the new Travel Time feature in Calendar. Today I ran into a problem, however. I scheduled an appointment and put in the location address. When I went to enter the travel time, it only gave me two options: walking from work and driving from work. There was no option for driving or walking from home. This has never been a problem before. What's going on here?

From Calendar Help:
Choose to see travel time from your starting location to the event’s location.
To set your starting location, Calendar first looks for your location in any events that are up to three hours before this event. If Calendar doesn’t find a location, it uses your work address during work hours and your home address during other hours.

How can i calculate execution time for methods?

I'm making a project that i want to calculate execution time for a
method in "miliseconds" or "microseconds".You see,I have a sort algorithm and i want to calculate execution time of this algorithm.How can i do?
Thanks...

Just remembered.
The answer you get isn't trustworthy below a hundred millis, so you may need to sort a hundred or a thousand times to get a reasonable elapsed time. You also need to run the test five or ten times and take an average. In Windows you should fire up the Task Manager and be sure that your other CPU usage is as near to zero as you can get.

How does optimiser calculate profit for profit maximisation

Hi Experts,
I have a basic question-
when we work on 'profit maximisation' how does the system calculate profits. As I understand the calculation is revenue- total cost. costs is what we define in the system. But how is the revenue calculated?
What it the logic where profit maximisation is selected over cost minimisation?
Regards
Manotosh

Hi Manotosh,
For answering the first part of your question, I am just copy pasting the F1 help for the field from Optimizer profile:
"Profit Maximization
Use
It is the optimizer's objective, when using either of the two possible options: cost minimization or profit maximization, to determine the most cost-effective solution based on the costs defined in Cost Maintenance.
If you choose Profit Maximization, the system interprets the Penalty for ND field (penalty costs for non-delivery) in the product master (tab page SNP 1) as lost profits. In this instance, the total profit achieved by a plan is calculated according to the following formula: Total of all delivered location products, multiplied by the penalty costs for non-delivery that have been defined for these location products, minus all the costs defined in the optimizer cost profile (such as production costs, storage costs and transportation costs). The total profit is displayed, when you run the optimizer in interactive planning within Supply Network Planning (on the Solutions tab page)."
For second part, someone who has worked on solution design in a project where Optimizer was used might possibly give a good answer. I am not very sure, though I can make a guess as follows:
You would go for cost minimization in a scenario where your requirement would be to minimize overall cost, even if it leads to non-fulfillment of requirement. Could be a scenario where e.g. lost sales are not very critical for you. e.g. products like generic bulbs, etc. On the other hand, where you want that the requirements fulfillment should also be one of the key objectives, you would go for profit maximization. This could be a case where brand plays a major role e.g. TV, costly gizmos, etc.
Hope someone else will correct me, or add to this.
Thanks - Pawan

How does one SUCCESSFULLY transfer Time-Machine backup to a new (larger) hard disk drive using OSX 10.5.8

I have read a number of articles about how to transfer a complete Time-Machine backup to a new (larger) hard disk-drive. Some of these articles are specifically for OSX10.6 users, which are not applicable to me since I am operating with OSX 10.5.8.
However, I have tried several times to use the Disk Utility 'Restore' function, dragging my old time-machine volume into the 'Source:' box and my new volume into the 'Destination:' box. This works, of sorts, BUT the newly created volume on the new larger hard disk-drive remains the same size as the original volume on the old Time-Machine HDD, with no apparent way of increasing the new volume's size. So I am not really any better off:
E.g. the total capacity of my new HDD is stated by 'Disk Utility' to be 465.8 GB, of which I'm told 228.2 GB is used for the Backups.backdb folder, but only 4.6 GB of free space is actually available. Yet under the 'Partition' tab of 'Disk Utility' it tells me that there is still 236.4 GB of available space.
Does anyone know how to resolve this issue without upgrading to OSX 10.6?

First, how did you prepare your new drive? See:
Drive Preparation
1. Open Disk Utility in your Utilities folder. If you need to reformat your startup volume, then you must boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (for Intel Macs) or APM (for PPC Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
If you plan to partition this new drive then be sure you create a larger partition for TM than your old volume.
Next, clone your old TM volume:
Clone using Restore Option of Disk Utility
1. Open Disk Utility from the Utilities folder.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4.Check the box labeled Erase destination.
5. Select the destination volume from the left side list and drag it to the Destination entry field.
6. Select the source volume from the left side list and drag it to the Source entry field.
7. Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive.

How does Calendar coordinate Time Zones for events?

By clicking a link at my seminar's web site, I told Mountain Lion Calendar to store an upcoming event that takes place in the Pacific Time Zone. I am in the Central Time Zone. If I visit Calendar, the event shows the Pacific Time start. How do I get calendar to show me the Central Time start when I go to Calendar. I don't want to have to guess which is which?

Mail Preferences. I think this is what Kappy is referring to if you haven't found it.

How does LabVIEW calculate filter coefficients?

I am attempting to develop a model for a post - processing routine that uses a cascaded IIR lowpass filter, in order to demonstrate to a customer the performance of our data acqusition system, without divulging our proprietary source code. Does anyone know how LabVIEW calculates filter coefficents?

Greetings efelgemacher!
I'm going to take a guess, but don't quote me on this. Both Matlab and Labview use IIR to synthesize analog filter prototypes....in a way, it's sort of "dumbing down" of an IIR response to get an analog equivalent. If you "drill down" through any of the Analog filter vi's you will see that they ALL use Digital filters just with analog paramaters plugged in.
At any rate, the polynomials have been catalogued for decades now, and I suspect they reside in a library somewhere in Labview..at least in "low resolution" form, rather than being generated from scratch every time. It would take very little reiteration to generate a couple of more decimal places using the IIR engine.
Again, just an educated guess.

On iCal,how to change the travel time mode from car to foot?

on iCal (Mavericks), how to change the traveltime mode before an event ? i only have the "time" choice with "5 min, 15 min, 30 min, 1 hour, 2 hours". I would like to choose "foot/walking" , "car" or "Train/bus".

America is only one of 197 countries in the world. So if you do not use a bike, your feet or public services to travel so, maybe 196 other countries do it :-)

How does someone get their Time Capsule serviced?

Hi all,
My 500gb Time Capsule has started to show the dreaded "Volume Can Not Be Mounted" error that I've seen mentioned on this message board a few times. This has been happening for both my computer (a MBP) and my fiance's computer (a MB.)
I tried doing a quickformat of the disk, and then after that was complete, tried backing up again and got to about 1.5gb before it failed. The disk is again, not mountable.
Thinking there might be a bad sector on the drive, or something similar, I tried doing a 1-pass secure erase, figuring that it would force the drive to go through every sector and mark bad sectors.
Well, it's been 4 days now and that first pass of the secure delete is still going. I think my Time Capsule is just busted (the router aspect still works.)
I tried going to the self-serve warranty pages, but after putting in all my info I'm presented with two options (both of which don't seem valid.) One was for the Genius Bar, but I can't seem to schedule a Time Capsule appointment online with them (only Mac, iPhone or iPod.) The other was for authorized service centers (all of them seem to be Carry-In Mac Only).
Do I schedule a Mac appointment with the Genius Bar? Can I just do an online warranty repair/replace? Maybe single pass secure erases are supposed to take over 4 days? (I really doubt that...)
Thanks!
Nick

I think you'll have to talk to Apple tech support (and they'll have you do all kinds of tests), or else you can go see a "genius," which would get you a new Time Capsule more quickly if yours is defective. Sign up for a "Mac" appointment.
