numerical integration – Levin Rule Integrate Power of Oscillating Function

I want to numerically integrate a function of the form:

    NIntegrate(Exp(I a x) x^-n (1+Exp(I b x))^n,{x,1,10^4}, 
    Method -> {"LevinRule", "LevinFunctions" -> {"TrigRelated"}})

BTW, Mathematica understands this better using Euler’s formula exp = cos + i sin .

The Levin Rule wants a explicit oscillating kernel like Exp(I 1/50 x) . The obvious solution would be to expand the bracket using the binomial theorem and then there would be contributions like Exp(I (a+l b) x) – oscillations with well defined frequency. But then I need to compute N integrals instead of 1 and there will be cancellations.
Is there a smarter way of telling the Levin Rule what to do than the Binomial expansion?

sharepoint online – Power Automate – Changing a column’s properties removes it from the schema

Before I go tear apart an entire workflow and app to fix this, I wanted to see if there was a simpler solution.

I have a flow in SPO that needs to set a People column with an “Update Item” action. Originally that column was set to allow multiple people, and that was fine. Then I ran into an issue where I had to switch it to single selections instead. That broke the workflow, naturally. At first it was giving me an error saying the field didn’t exist anymore and should be removed from the schema of the update. I just deleted and re-added the “Update Item” action, but now the People column isn’t even showing up.

My only idea is to completely rip out and recreate the column, but that would bust various parts of the workflow and its associated app. Any thoughts?

Enter a valid json when using Power Automate to manage Sharepoint Meta Data

With a flow running, I’m able to copy files from a network location to a Sharepoint on-prem 2016 site.  I’m struggling with setting the Category metadata for the files that are uploaded. All the files belong to the “Human Resources” Category. The error I receive is “Enter a valid json” , and I’m copying in a peek at the code.  What am I doing wrong?

power – Looking for an adaptor to use my computer from France in Uruguay

Uruguay uses 220V at 50Hz mains power supply similarly to European countries. The plugs are mostly type F, commonly known as Schuko:

Type F power plug

Or type C, commonly known as Europlugs:

type c socket
(source: worldstandards.eu)

Coming from France, this means that in most cases you will not need an adaptor. However, you might find other types of sockets – type I and type L – for which an adaptor is required. This assumes that you are using appliances with type F plugs.

power automate – Multiple changes to SharePoint Document Library but I only want to send one email

I have a document library in SharePoint Online. The end user submits about 30 documents to add metadata and to be approved. One column of the metadata is used to group the documents together. If the documents are approved no email is necessary. If they are rejected the library curator selects all the documents in the group and through bulk editing fills in a multi-lined column marked Deficiency with the reason why of the rejection, then changes another column to Rejected to initiate the workflow.

This sends out as many emails as there are document in that grouping. Is there any way to send out just one email when the grouping set is rejected?

sharepoint online – Reading and updating complex JSON Object in power automate

We have a requirement to update the content in the JSON Stored as multiline text column in one of the list, when one of the item in the another list is updated we need to update the JSON data stored in the item of the source list.

here is the sample json

    [
{
ClientStoryId:
ClientStoryName:
AssetID:
AssetName:
UserName:
UserEmail:
UserID:
}
{
ClientStoryId:
ClientStoryName:
AssetID:
AssetName:
UserName:
UserEmail:
UserID:
}
{
ClientStoryId:
ClientStoryName:
AssetID:
AssetName:
UserName:
UserEmail:
UserID:
}
]

When a user gets added to the Users List with client story and assetName we need to appropriately update the userdetails in the JSON which will be stored as multiline of text in another list.

Kindly help me.

20.04 – Ubuntu 20.4 Settings opens slow, battery indicator disappeared, power statistics won’t open

I have 3 issues that I suspect are related.

The Power and Displays pages in settings take 5 to 10 seconds to load, the battery indicator in the upper right corner is missing, and Power Statistics refuses to open.

I’ve reinstalled gnome-control-center and the ubuntu-desktop.

Gnome Tweaks has the option to show the battery indicator but it does nothing.

All packages are upgraded
