QUESTION
I'm trying to reorganize the expression polin:
...ANSWER
Answered 2021-May-26 at 09:08Your expression looks like the following:
The order of terms in the polynomial in the numerator goes from -1 to 3 while the denominator goes from 0 to 3. This means that it is bottom-heavy and you will get a 1/s term. This means that there does not exist constants a, b, c, d, e such that polin == (a)*s^4+ (b)*s^3+ (c)*s^2 + (d)*s + (e).
The best you can do is an approximation using a series expansion. It is important to note that one of the terms is 1/s and so you will get something of the form (a)*s^4+ (b)*s^3+ (c)*s^2 + (d)*s + (e) + (f)/s.
To solve this, you could manually get the coefficients or multiply polin by s so that all powers are nonnegative.

QUESTION
I have created this EntityListener:
...ANSWER
Answered 2021-Apr-23 at 17:44EntityListener is JPA feature, not Spring ones. You don't need to declare a listener as a @Component, because the JPA provider shall instantiate it.
That's what actually happens here:
- Spring instantiates a
AListenerbean and injectsARepositorydependency as expected. - JPA provider sees that
AListeneris an entity listener and tries to instantiate it. In order to do it needs no-args constructor (remember that JPA provider knows nothing about Spring and its beans) - Instantiation fails, because no-args constructor is not found
You can check it by removing the ARepository dependency and adding some logging statements inside the constructor.
If you do need some Spring beans inside the listener you can make them accessible as static fields in some utility class.

QUESTION
I'm trying to explode a column of a dataframe to get multiple rows. The column to explode it's called keywords, which are a list of emotions returned as keywords from the package FlashText. This means if a keyword is in the text column (column with sentences), then it will return that emotion or multiple emotions corresponding to that sentence
If I use an example dataframe created by me, this works perfectly with an expected output, however when applied to the dataframe explode it returns a random combination of rows.
I thought this unexpected results were because the dataframes have duplicate indexes, however, drop them gaves the same wrong result.

QUESTION
I'm trying to implement my own cyclic redundancy check (CRC) in Python. The layout of my program is as follows:
- random_message(n) generates a random byte message of length n.
- Generate the checksum value using the CRC code
crc16. - Run the corruption code
corrupt_dataon the generated message. - Check whether the checksum is different or not (I did this using
==). - Repeat steps 1 to 4 many times to see how often an error (i.e., the corruption) goes unnoticed.
I am confident that the methods crc16 and corrupt_data are correct, so I don't think there's much reason to analyse them too closely. I think the problems start with my use of byte strings in the second half of my program, after those two methods.
My code is as follows:
...ANSWER
Answered 2021-Mar-20 at 07:01Your issue is not with the byte strings really, it's a logical error. You're trying to corrupt the wrong thing. You don't want to corrupt the checksum, you want to corrupt the original message and then take a checksum of the corrupted version. Then you can compare if the two checksums match or not.

QUESTION
I'm trying to make an API using .NET Core 3.1 with C# programming language which utilizes Firebase real-time database from Google through FireSharp Nu-Get package. When I ran it, I got this exception: System.Text.Json.JsonException: A possible object cycle was detected which is not supported. This can either be due to a cycle or if the object depth is larger than the maximum allowed depth of 32. I read here that I can just install Microsoft.AspNetCore.Mvc.NewtonsoftJson package and ignore the reference loop handling, which works fine. But the data format looks unreadable, very hard to deserialize, and way too long:
ANSWER
Answered 2020-Dec-14 at 06:31So, I solved this. I went back to here and apparently someone said the error I got in the first place was because not all async functions had been waited or handled properly. So I went through my codes once again and finally found the problem in my controller. After I made my controller async then changed the return type into Task, everything went perfectly fine!

New here with my first question. I have searched for several days now, and cant figure what I am doing wrong. I am new to React and development as a whole, so that most likely is my biggest hurdle, however, from what I can tell, this should work.
I am trying to render images in an iterated component dynamically. Images are hosted locally in the public folder. While I'm working this out, I'm using JSON server for my data to iterate from. When I use the full path in my component all is fine:
...ANSWER
Answered 2020-Dec-11 at 18:21JSON format does not support template literals and there are no env variables.
Therefore, you need to remove the template literals and bring your json file to the following form, so that you get a relative path:
QUESTION
Using R, I would like to count the number of points within a polygon according to a specific criterion (a temporal window).
I have the following data:
- Geo-located survey data that include the date of the survey interview. Thus, I am able to pinpoint exactly when and where each survey was conducted and to map them out across the United States.
- Geo-located data about political rallies across the United States. These also include the date.
Using QGIS, I created a set of circular 50 mile buffers around each survey respondent. My goal is to count the number of political rallies that falls within each respondent's "buffer" within a specific time frame preceding the interview. The 50 mile buffers created in QGIS retain all variables of the original data, including the date of the interview.
DataUsing QGIS, I created some mock shapefiles with dates and locations to aid in replication.
ApproachI am trying to use GISTools::poly.counts to count the number of rallies within different temporal windows (30 days, 90 days, etc.).
Generally, to count the number of points within a polygon, I would simply use:
...ANSWER
Answered 2020-Dec-07 at 21:23I approached your problem in a different way by using the sf package instead of GISTools. The algorithm is straightforward and you can easily adapt it to your GISTools::poly.counts() method:
- Read in shapefiles (
st_read()) - Filter shapefiles by date using
dplyr(make sure you've got Date objects to create the windows) - Find the intersection of whichever points data with the rally buffer (
st_intersection()) - Get the size of the intersection object (
nrow())
Likely you'll have to tweak the function parameters to make sure it works correctly for the real data. Below is an example using your mock data.
Setup and read in the data (note stringsAsFactors=F just makes the dates easier to create; not necessary for R version 4.x).

we got a homework in school to make this type of programme I share here. I have it done its working but I need this: If I put 2 or more same lowest or highest numbers I need to print position of all same lowest and highest numbers. And I am stucked here. Can you help me, Thanks
code:
...ANSWER
Answered 2020-Nov-03 at 10:56You should:
- Allocate an array to store all min/max positions.
- Remove all elements and store new position if the record is breaked.
- Add new position to the list if the record is tie.
It will be like this (only max is shown, min can also be done like this):
