streamlines | Streamlines calculator | Map library

I have a List tennisLines that contains several lines about tennis matches, each line contains information about one tennis match with the name of the tournament, location, round, winner, loser, date etc. separated by a semicolon.

Each tournament has a unique name and contains several tennis matches. I created a TennisTournament class which include the name of the tournament, the location, and the associated tennis matchs Listetc. The class TennisMatch contains the winner, the loser and the round.

I'm trying to convert the list tennisLines into a List tennisTournamentList so basically turn each line into a TennisMatchs instance and add each group of tennis matches into the tennis match list to finally create a TennisTournament object.
I've created a stream Stream streamLines and I can't figure out how to map them into an object that contains another object.

That's an extract of the list, that should be eventually one TennisTournament object, that also contains a list of size 27 List

In the image below I have an awful calculator which currently the company I work is using. Because everything is in the same column, it makes it challenging to automate. I have created a new table that streamlines everything into separate rows but because this is part of an SOP it still has to be used for now.

As a result, I'm wondering if it's possible to copy down a block of formulas/values.

In the desired output, all Values are constant formulas based on the Name of the impurity in green. Essentially the Green cells define a block of the same formulas just relying on a different Impurity. The calculations work by looking up values elsewhere using the name of the impurity and calculating thereafter. For Simplicity of the question I haven't included these formulas But just as a little more context with the first block:

• Impurity Name e.g. Antimony (pulled from list)
• 0.0003 = XLOOKUP(D3,B3:B8,C3:C8, "-") Please note that Column B in reality is just a section of a table on a different sheet so column C n the fouls is just the adjacent values)
• ppm. This is just standard text. No formula.
• MADL (ug/day) - Standard Text
• =XLOOKUP(D3,B3:B8,D3:D9,"-")
• NSRL (ug/day) - Standard Text
• =XLOOKUP(D3, B3:B8,E3:E9, "-")

In the middle, I essentially have these "Blocks" and on the left, you can see the source data for the impurity names.

This isn't essential to solving, but I do come across similar issues and have been interested in position a similar question in the past.

I have tried indexing columns and Offsetting values but so far have not been successful.

Essentially I have F3 = B3 and when the block is pulled down, F10 = B4, F17 = B5 and so on.

I have had some success in the past copying down blocks in this way but here unfortunately not. Another idea I had was to create a helper cell that somehow only inserts a character e.g. "*" And then apply a condt lookup function based on this, but again I just don't know how to to get it to skip to the next value in the source column.

If anyone has done something similar I would be interested to know your solution.

Finally, although I think I could produce this in power query a. I don't really want to because its a terrible way to produce a table anyway, but also I think there needs to be some flexibility here so that the users can actually enter in data is they wish, but power query will remove this upon refresh. So really I'm just looking for an excel formula solution.

I'm trying to extract streamlines from an unstructured grid by using the vtk python library:

I have a csv file, containing results from a Computational Fluid Dynamics (CFD) simulation (a sample of my csv file is attached as a google drive link; file size: 226KB). In particular, the csv file has information (x, y and z coordinates and velocity in three directions, so a total of six columns) about multiple streamlines (number of streamlines may vary depending on the case). Information about streamlines are separated by two empty rows (see the sample csv file). Streamlines have may have different number of rows.

I need to read this csv file, and organize its data into a list of Pandas datafreames, like:

For some development technologies and their projects data, I am trying to get keys and values using for loop.

I am trying to make separate section of development technologies and then trying to put their projects inside that section, but I am not able to iterate, please tell what is wrong with my code.

I am able to access all web technologies but don't know how to run nested loop

What I know is after JDK 1.2 all Java Threads are created using 'Native Thread Model' which associates each Java Thread with an OS thread with the help of JNI and OS Thread library.

So from the following text I believe that all Java threads created nowadays can realize use of multi-core processors:

Multiple native threads can coexist. Therefore it is also called many-to-many model. Such characteristic of this model allows it to take complete advantage of multi-core processors and execute threads on separate individual cores concurrently.

But when I read about the introduction of Fork/Join Framework introduced in JDK 7 in JAVA The Compelete Reference :

Although the original concurrent API was impressive in its own right, it was significantly expanded by JDK 7. The most important addition was the Fork/Join Framework. The Fork/Join Framework facilitates the creation of programs that make use of multiple processors (such as those found in multicore systems). Thus, it streamlines the development of programs in which two or more pieces execute with true simultaneity (that is, true parallel execution), not just time-slicing.

It makes me question why the framework was introduced when 'Java Native Thread Model' existed since JDK 3?

How can I remove a streamplot from a Matplotlib plot without clearing everything (i.e. not using plt.cla() or plt.clf())?

plt.streamplot() returns a StreamplotSet (streams in the following example), which contains the stream lines (.lines) and arrow heads (.arrows).

Calling streams.lines.remove() removes the streamlines as expected.

However, I couldn’t find a way to remove the arrow heads: stream.arrows.remove() raises a NotImplementedError, and stream.arrows.set_visible(False) has no effect.

I have been working on this for a while and just can't seem to find the answer to what I need. Suppose I have a dataframe as below.

What I would like to do is fill the last three rows of df['gender'] based on the value in df['home_work'] column, specifically if home_work > 9, then m, if not, then f. Please keep in mind this is just a made up dataset and I don't mean to offend anyone, I promise!

I have created a slice. On this slice I have generated 2D streamlines. I would like to have arrows to represent the direction of the streamlines in the following manner:

I tried to create them using Glyphs. Below is the screenshot of the settings I used in the Glyph filter:

I am getting the following as the output:

As one can see the arrows are not in line with the streamlines. Can someone please help me get the desired output? Also I just want the arrow head and not the arrow itself.

When I use the edge arrow I am getting the following (Please note that I have rotated the slice to show that the arrow head is appearing perpendicular to the streamlines):
