![]() aka Hawking radiation.īy contrast, curvature in one direction which is equivalent to acceleration in flat space induces photons in random directions (Unruh effect). We know intense regions of curvature, for example near a black hole horizon, induce a flow of electromagnetic waves (and, less so, other particles). Zooby Asks: Will gravitational waves decay into photons? (and by how much?) How can I do that? I'm dealing (substation, power_tower,etc) with Dataframes variables. I don't want this to happen, I want the power lines present but only inside "area" with the same escale as the first image, if it's out of that area/background I don't want to see it. Image below is when I have only the substations, power towers and the background.Īnd this one is when I have everything together like the code I developed above. Power_ot(ax=ax, facecolor="green", alpha=0.7) Power_ot(ax=ax, facecolor="dimgray", alpha=1, markersize=10) Print("Retrieved", len(power_line), "power_line objects within the area") Power_line = gpd.sjoin(power_line, area, op='intersects') # perform a spatial join to keep only power lines that are within the area Power_line = ox.geometries_from_place("Trafaria, Portugal", tags_power_line) Print("Retrieved", len(power_tower), "power_tower objects") Power_tower = ox.geometries_from_place("Trafaria, Portugal", tags_power_tower) Print("Retrieved", len(substation), "substation objects") Substation = ox.geometries_from_place("Trafaria, Portugal", tags_substation) ![]() Please let me know if I need to explain anything further, or if there is some other information which would be helpful.Īrea = ox.geocode_to_gdf("Trafaria, Portugal") I am using Python so any library suggestions would be appreciated as well. Please, if you have any suggestions I would be very grateful. So far I have looked into connected components, associative groups,and graph theory. So I am looking for resources or suggestions on how to deal with a longitudinal grouping problem. Issue: Super Messy (although might be fun to try and implement) I would be associated with each roommate my roommate has had. Weak connections eliminated (1-2 associations or less). Webbing: using component connection to attach each individual through the time periods. Best idea so far, but might make analysis a little more difficult. Multiple IDs: Assigning IDs at each period of data and then creating a graph for association. Issue: hard to make a distinction who gets assigned captain. Issue: individuals breaking/split off from their households resulting inĬaptain/HeadofHouse: following one individual in the household at the start of the data, and grouping people who come into their household based on their assigned Captain ID. The PI is flexible on their definition of households and we have so far come up with a couple of ideas.Īnchor households: create household IDs with the linked addresses at the beginning of the study, and having those individuals associated with this starting ID. The dataset doesn't keep track of people under 18 so when they come of age they pop up in the period of data where they turn 18.People start their own households with other people.We want to attach a household ID to each person, which they can be associated with at any point in the data. So we have this data set spanning multiple consecutive time periods. However, the difficulty is the dataset/analysis is longitudinal. And from that household ID, my PI wants to investigate households/families migration overtime due to cost of living increases/decreases. I want to create a group ID based off shared addresses (the working idea: people who share the same address can be considered as part of the same family/household). I have a large data set which contains individuals and the address where they live. The Texdistribution in Mactex 2010 (Texlive).Alex Winters Asks: How to create group IDs for people in longitudinal data Have I done anything wrong? I'm using Texshop and Bibdesk to create my files. If I check the aux file I can see, that there is no \bibdata command, but why and how do i get it to be there. Warning-I didn't find a database entry for "tipler" I found no \bibdata command-while reading file x I have the following files my main file: \documentclass,Īnd finally the aux file: I run bibtex - after I ran pdftex at least two times - I get an error: This is BibTeX, Version 0.99d (TeX Live 2010)
