rbo | Implementation of Rank-biased Overlap | Data Mining library

Dataset:

I have two rotation matrix suppose initial basis O is identity in R^3 and rotation RAO transforms a point in O into basis A and rotation RBO transforms a point in O into basis B

I tried to calculate angle differences between RAO and RBO like:

I wish to identify and then create a list in python all stocks (Capitalized Letters) mentioned here..

The problem I have a large text doc with many areas containing 2 3 or 4 Capitalised letters however i only want to get the ones that precede a paragraph ending (stocks-to-watcch are in the following paragraph):

i.e SE, SAM, PYPL, LAD, GLOB .....etc

Not sure if non capturing groups is the way to go or whether I can do look behinds.. if I do non capturing groups to I was thinking something like this would work but it doesn't... any help greatly appreciated

I am working to further optimize the following query. I have already had a lot of success optimizing the query up to this point, but now I am looking for help from others for ideas. I appreciate your help.

The following query takes over 200 seconds to complete yet the two individual WITH clause queries (receiving_1 and receiving_2) that make up the "UNION ALL" take less than 4 seconds each.

• receiving_1 -- 58 recs in 3.4 secs; cost 295 (no UNION)
• receiving_2 -- 0 recs in 3.8 secs; cost 295 (no UNION)
• UNION ALL of 1+2 -- 58 recs in 203.1 secs; cost 300 (UNION ALL)

I was hoping "rownum" would help optimize the "UNION ALL", but it did not. This attempt was based on a note from AskTom --> Files --> SQLTechniques.zip (between 61 and 72)

When you have two queries that run light speed separately But not so together Generally a mixed “CBO/RBO” problem Use of RBO with a feature that kicks in the CBO Rownum can be a temporary fix till all things are CBO

NOTE: One optimization that avoids this issue is embedded replacement parameters or cursor parameters that greatly reduce the rows at key points in the query. However, because I need to run this query through a database link against a read-only database, the following options are not available for this query.

• dbms_sql over database link: query is too long; dbs_sql does not accept a lob over database link; also DBAs don't allow the running of any PL/SQL in the read-only database.
• pipelined function: pipelined function has known bug over database link between 19c and 11g so fails
• sys_refcursor via PL/SQL: cursors are not supported over database links
• set parameter values in PL/SQL package and use them in view: not allowed to execute any code in read-only database (I am still bugging the DBAs to allow this. This might be my best hope if I am not able to optimize the below query to run as a view.)

NOTE: In an attempt at providing a good test case with as little code as possible, the below SQL (4,584 chars, 88 line breaks) is a greatly simplified version of the actual SQL (93,683 chars, 2,014 line breaks) I am developing. The original SQL has already gone through several rounds of optimizations to bring the runtime down from over an hour to under 10 seconds. This latest challenge is that the SQL has to be rewritten as a view as opposed to a SQL file with embedded substitution parameters. The substitution parameters were key to the optimizations up to now. I am now refactoring the SQL to work as a view in Oracle 11gR2 to be called via a database link from Oracle 19c. A view has no parameters, obviously. The driving parameters (ledger, OU, period) will be WHERE clause conditions when querying the view.

Big picture: The actual SQL under development is an amalgamation of 6 report queries that share a lot of duplicated code. My work is to convert all six source report queries into an efficient extract for importing into a new database schema for reconciliation purposes.

For a C# .NET Core application I need to adjust an existing LINQ statement to include a WHERE clause condition based on a boolean property. And most of all, I want the query to handle the filtering so I will not pull in to much data into the application.

This is an example of the LINQ statement

I am new to OpenGL and i am working on a Voxelengine. I want to render my current scene to a texture and then render this texture on a quad. The problem is that i always get a black screen. when i multiply the frag color output by 5 my screen become grey. Therefore I think the problem is, that the texture don't get the output of my renderer. Rendering directly to the default renderer works fine so i think its a problem with my fbo.

Renderer.h:

I m Trying to Fetch Data by using Two Date column in PostgreSQL. It is giving me the correct the output according to the query. But it is not giving me my expected result.

In this Output i fetched data by using document_submission_date and received_date of February month but it is giving me some output of the month of march which I indicated with the blue sign. yap, for sure it is giving me the correct result according to the query. but i only want to return all data except the blue indicator (image above). this is my query given below..
