kandi X-RAY | ross Summary

ross is a Python library typically used in Financial Services, Banks, Payments, Simulation applications. ross has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has low support. You can install using 'pip install ross' or download it from GitHub, PyPI.

ROSS is a library written in Python for rotordynamic analysis. It allows the construction of rotor models and their numerical simulation. Shaft elements, as a default, are modeled with the Timoshenko beam theory, which considers shear and rotary inertia effects, and discretized by means of the Finite Element Method. Disks are assumed to be rigid bodies, thus their strain energy is not taken into account. And bearings/seals are included as linear stiffness/damping coefficients. After defining the elements for the model, you can plot the rotor geometry and runs simulations such as static analysis, Campbell Diagram, mode shapes, frequency response, and time response. You can try it out now by running the tutorial on binder.

Powershell: How to pick 1 result of many from Invoke-Sqlcmd Select statement

Asked 2022-Mar-29 at 05:23

When I run a SELECT statement using Invoke-Sqlcmd, I'd like to choose 1 out of X results to move forward with a loop. In the example below, I have multiple results for 'Bob' and I'd like to choose the appropriate one to continue working with the query to update his favFood (I know I don't have the code there but just giving an example of what I have so far)

In theory you don't need a loop at all, you could use the SQL IN operator and pass all the names of $nameList to your query. Then once you have stored the $result of your query, you can use Out-GridView -PassThru to have a popup DataGridView for you to choose a row, which would be stored in $choice.

ANSWER

Answered 2022-Mar-18 at 01:56

The problem is you have two arrays that you are want to traverse but only one FLATTEN,

thus you need another FLATEN, but the trick here, is that "Kitchen" has only one item in ITEMS which most XML parse incorrectly map to an object (aka this happens in snowflake also).

Thus you have to convert the output of "items" from "Room" to an array before you use it:

If I understand correctly, you would like to filter the dataframe to retain, for each run_time, the last two rows (or up to two rows) by match_datetime.

Simplified answer

This can be done relatively easily without any join, using GroupBy.tail(). (Note, my original answer was using GroupBy.rank(), but this is simpler, although slower):

How I can find the name by the set parameter?

Asked 2022-Jan-02 at 00:11

I am trying to write a program that will create a link to the API. To do this, I use bs4, with which I search for the div I need, but I get an error due to the program not working correctly. I want to find only this coin name that are in the coin list. How I can fix it? Please, give me a hand.

ANSWER

Answered 2022-Jan-02 at 00:11

There are two issues with your code:

This: if check_name == coins_list: will always return false, since check_name is a string and coins_list is a list. You want if check_name in coins_list:.
baseurl isn't defined in the code snippet. Change it to url.

Perform both these changes, and you should have a nonempty output in your text file. The URLs in this file appear to be well-formed.

why is this a meta-program?

See: SWI-Prolog Meta-Call Predicates

Meta-call predicates are used to call terms constructed at run time.

In this case passing in the predicate to call, Fact, then running it as a goal.

Since you are selecting bits of data from different levels of the input objects, you will need to specify the selection more precisely.

As your input consists of a stream of JSON objects, let's start with a function for reading one of those objects:
