kandi X-RAY | rbs Summary
RBS is a language to describe the structure of Ruby programs. You can write down the definition of a class or module: methods defined in the class, instance variables and their types, and inheritance/mix-in relations. It also allows declaring constants and global variables. The following is a small example of RBS for a chat app.

QUESTION
I can construct a spline of some 2-D data and query area integrals quite easily with scipy.interpolate.RectBivariateSpline
. But there is not a function for easily/quickly calculating line integrals over such splines.
ANSWER
Answered 2022-Jan-04 at 22:04A bivariate spline surface is piecewise polynomial. In the case of a bicubic expression, for instance, by substituting the parametric equations X = X0 + t.δX
, Y = Y0 + t.δY
, you obtain a sextic polynomial in t
. The parameters X0
, Y0
, δX
and δY
as well as the integration range are found in every grid cell by tracing the line segment and intersecting it with the grid. Then if scipy is kind enough to give you the coefficients of the bivariate polynomials crossed, you can obtain those of the polynomials in t
.
If the expression of ds
is √dx²+dy²
, this amounts to √δX²+δY².dt
and the antiderivative is elementary. So it "suffices" to enumerate the polynomials in the cells crossed and compute all required coefficients.
If the expression is √dx²+dy²+dz²
, you are stuck because by the chain rule dz = (δX.P(t) + δY.Q(t)) dt
, where P
, Q
are polynomials, and the integrals do not have a closed-form expression.
Note. Due to the complexity of the polynomials expansions, it is not unthinkable that a straight Simpson integral evaluation could be faster and as accurate, for a reasonable step size.

QUESTION
I wrote the following program in nasm on a Windows 10 64bit machine
...ANSWER
Answered 2021-Dec-19 at 00:56The first time through the outer loop, [ebp-8]
counts down to zero. The next two times through the outer loop, [ebp-8]
is already zero (or less), so the inner loop only executes once. For a total of five calls to print.
Note that the subsequent executions of push [h]
don't change [ebp-8]
.
On the second iteration, it writes to [ebp-12]
and on the third iteration it writes to [ebp-16]
, because the stack pointer continues to grow downward with each push.
To fix this, I suggest:
- Add
sub esp, 8
right aftermov ebp, esp
. - Change
push [w]
tomov eax, [w]; mov [ebp-4], eax
. - Change
push [h]
tomov eax, [h]; mov [ebp-8], eax
.

I am trying to filter a .tsv file by selected relevant rows. I had done this a few days ago with the same file, and had had no problems. However today, as I was filtering the file I had the error as below: awk: syntax error at source line 1 context is >>> /Users/rbs/Desktop/results.e <<< ntries.tsv awk: bailing out at source line 1

QUESTION
ANSWER
Answered 2021-Oct-17 at 10:15You get that result because when you apply()
the extractGrammar()
function to your DataFrame, it passes each row of the DataFrame to the function. Then when you access the ['POS Tag']
column, it is not returning that entire Series, but rather the contents of that POS Tag
cell for that row, which is a list. Lists do not have a map
method. If you are trying to count the occurrences of the second element of each tuple in the POS Tag
column, you could try the following:

QUESTION
TypeError: unsupported operand type(s) for /: 'str' and 'float'
I'm making a football game, and I get this whenever I try to run the following code to determine how far a play will go.
playdistance = round(random.uniform(float(rbs.get(possession)[-2:]/float(30.0))-2.5,float(rbs.get(possession)[-2:]/float(30.0))+5.5))
"rbs" is a dictionary containing all of the teams' running backs and overall stored like 'NYG':'Saquon Barkley 99'
where it contains the name and then how good that player is on a scale from 0-99. I stored it like this so that I can use [-2:] to get how good the player is, and [:-2] to get the name of the player.
"possession" is the team that has the ball, so that I can pull the running back's name and skill from the dictionary previously mentioned.
What I'm confused about is how I'm getting the previously mentioned error when both of the arguments in the division are floats, and neither are strings. I've tried converting the 30 divisor into a string, a float, and I've also done that for the first argument.
I'm sure this is a pretty dumb question as I am pretty new to coding and python, but if someone could help me out that would be awesome.

i am trying get list of intermediate railway stations information from https://rbs.indianrail.gov.in/ShortPath/ShortPath.jsp, by providing source and destination stations it displays list of intermediate stations within a table. but its hiding some intermediate stations under several buttons to limit the size of the table,i think. on clicking the buttons, it pushes hidden data on to the table. using jsoup i could get initial data in the table. but dont know how to get the hidden data. on button click, one javascript function requesting data using POST method from https://rbs.indianrail.gov.in/ShortPath/StationXmlServlet by passing "route=inter,index=1,distance=goods,PageName=ShortPath" as parameters and the response is in json. as the parameters are not relevant to the displayed table, i can not make direct request to the https://rbs.indianrail.gov.in/ShortPath/StationXmlServlet.

QUESTION
I am working on a bar chart displaying time intervals.
The intervals are defined events objects, which have a unique id
and two days start
and end
.
The rule is to display one line if events never overlap eg when ordered, the start of event X is never before the end of event X-1.
If there are overlaps, we add the minimum necessary number of lines to display bars so there are no overlaps on the graph, and we want graphs with later start
be above the ones with earlier start-date, yet not by violating the first rule.
I did the following:
