The issue is that your filter needs to be centered in the middle of the image. So you need
I'm writing a program, that takes 200 planes distributed with the poisson distribution over 12 hours and these planes need to land at an airfield that only has 1 runway. I use the reverse CDF method from the exponential distribution to determine the inter-arrival times. However, I can't seem to calculate the waiting time in the air.
E.g. a plane arrives at 100 seconds, takes 75 seconds to land and is done at 175 seconds. Plane 2 arrives at 150 seconds and must wait 175-150 = 25 seconds. How do I program a variable that my function can output, that takes into consideration that the waiting time also can be 0 seconds?...

This is a single-server queueing system, where the server is the runway. General discrete event systems such as this can be programmed using event scheduling, based on a priority queue to determine what's the next thing to happen. You can read the PDF file at this github repository for a fairly complete discussion.
However, the single server queue has purely sequential logic and can be implemented as a loop using the following recurrence relations:
- arrival_timei ← arrival_timei-1 + interarrival_timei
- start_landing_timei ← max(arrival_timei, finish_landing_timei-1)
- finish_landing_timei ← start_landing_timei + landing_timei
In words, from a plane's perspective
- you have an arrival event
interarrival_timetime units after the last plane arrived (this is your Poisson process);
- you can start landing procedures either when you arrive, or when the previous plane finishes landing, whichever comes later; and
- the landing is actually completed
landing_timetime units after you started landing.
You can initialize the imaginary zero'th airplane's
finish_landing to be 0.0, put the logic outlined above in a loop, and iterate through either the specified number of aircraft or until the stopping time is reached. Since the logic is purely sequential, you can lose the indices and just recycle the variables. In pseudocode, and assuming that
landing_time() are iterators which cough up the corresponding next value on demand:

Sorry, I'm not quite sure how to describe my issue.
For an online python course I'm following there's an exercise I can't figure out. (raise NotImplementedError() refers to lines I need to input code).
The line of code
station_years = 2019 - station_start_years[selected_station] is what I'm stuck on. I'm aiming for the list "station_start_years" to chose its value based on my selected_station value, which is based on station_names.
num = int(input('select a station: ')) was inserted by me so may be wrong.
Thanks for any help, I've read through the exercises but am lost.Read-only code cell
Read-only code cell
station_names = ['Harmaja', 'Kaisaniemi', 'Kaivopuisto', 'Kumpula', 'lighthouse', 'Malmi airfield', 'Suomenlinna aaltopoiju', 'Vuosaari harbour']
station_start_years = [1989, 1844, 1904, 2005, 2003, 1937, 2016, 2012]
Below we can define the selected station: #raise NotImplementedError()
num = int(input('select a station: '))
selected_station = station_names[num]
Next we find the location of the selected station in the list of station names:Read-only code cell
station_index = station_names.index(selected_station)
Now we can calculate the years the station has been operational:YOUR CODE HERE
station_years = 2019 - station_start_years[selected_station]
Now, we can print the station name and number of years of operation to the screen.
A sample print statement on screen is
'The Helsinki Harmaja station has been operational for 30 years.' The print statements should work for all listed stations only by modifying the
selected_station -variable that is defined earlier in this problem.

You find the index of
station_names but then you use
selected_station (which is the name of the station) to index your
station_start_years list. You should be using

I am trying to plot Starbucks locations from CSV data onto a city shapefile that I've loaded in. I want to essentially create a heat map or simple scatter plot with the Starbucks locations on the city shapefile. The csv file has longitude and latitude points.
This is the code I have so far, I'm having trouble with merging the two files together though. Please let me know if you can help!...
ANSWERAnswered 2019-Dec-23 at 07:26
Since the streets are a line geometry and the Starbucks locations are point geometries, they can't be merged into a single shapefile. However, they can still be plotted on the same map. I use ggplot here, but you can use any number of other plotting tools.
First step is to turn the Starbucks csv from a regular dataframe with some lat/long coordinates into an sf object that has geometries using
st_as_sf(). Then, re-project that to match the projection for Dallas streets using
I declare a leaflet map with...
ANSWERAnswered 2019-May-08 at 17:53
I think the issue comes from trying to change the map view (possibly through openPopup with autoPan, which is on by default) too often, typically in a loop without giving any delay for the map to actually set the view between each call.
IIRC, this is already identified as a limitation in Leaflet, but I could not find the exact thread in the issue tracker unfortunately.
Normally, a very simple fix is simply to remove the map view changes within your loop, and keep only the very last one.
In your case, if you have the default behaviour of only 1 Popup being opened at a time, then that would definitely be a valid solution: just open the popup of your last Marker.
If you did configure your map to keep several Popups open simultaneously, and you do want to open all of them through your loop, then make sure to disable autoPan (at least during your loop).

Try to use below code snippet. Actually issue is you want dropdown to take space below 1080px but above 1080px you want it to be absolute, so that navbar doesn't get expanded.
