kandi X-RAY | marvin Summary
Conducting examination and answer sheet evaluation are hectic testing tools for assessing academic achievement, integration of ideas and ability to recall, but are expensive, resource and time consuming to generate question and evaluate response manually. Manual evaluating of answer sheet takes up a significant amount of instructors' valuable time and hence is an expensive process. Also different security concerns regarding paper leakage is one of the other challenges to conquer. This project aims to build an automated examination system using machine learning, natural language toolkit (NLTK), python environment, flask framework, and web technologies to provide an inexpensive alternative to the current examination system. We implement a model to automatically generate questions with their respective answers and assess user responses.

QUESTION
My goal is to merge two datasets using date ranges. Dataset1 contains patients stays in a hospital overtime. Dataset2 contains room information overtime. My goal is to identify what type of room the stays were in my Dataset1. It can get complicated since room type in some hospitalizations can change. For example patient 101 second hospitalization was part ICU and part Emergency.
Dataset 1

QUESTION
Below is an example of my data (Room and Date). I would like to generate variables Goal1 , Goal2 and Goal3. Every time there is a gap in the Date variable means that the room was closed. My goal is to identify consecutive dates by room.
...ANSWER
Answered 2021-May-11 at 19:34# Original Data (Note I use a different method to convert the Date to date format below)
df <- data.frame("Area" = c("Upper A", "Upper A", "Upper A", "Upper A",
"Upper B", "Upper B", "Upper B", "Upper B"),
"Date" = c("1/1/2021", "1/2/2021", "1/5/2021", "1/10/2021",
"1/1/2021", "2/5/2021", "2/6/2021", "2/7/2021"))
QUESTION
I'm trying to convert molecular smiles into fingerprints using rdkit. I have two smiles:
Nc1cccc(N)n1 and Nc1cc(CSc2ccc(O)cc2)cc(N)n1. The first one was expanded into the second one. In other words, the second molecule contains the first one in its structure.
What I did was use rdkit to remove the common part to obtain smiles of a fragment that differs (CSC1=CC=C(O)C=C1 in kekulized form). I'm trying to convert that fragment into a molecule and then to a fingerprint to calculate similarity with a reference molecule.
But I get an error: 'Can't kekulize atoms' with indices of those atoms. This is strange to me because all the smiles (the two input smiles and the resulting fragment smiles) can be easily visualized using MarvinSketch or Chemdraw (software for drawing molecules). I even had Marvin kekulize the fragment smiles and tried making a molecule from that but I still get the same error. Here is my code for removing the fragment:
...ANSWER
Answered 2021-Apr-29 at 16:05With fragment_smiles = 'Nc1cccc(N)n1' and a list like smiles = ['Nc1cc(CSc2ccc(O)cc2)cc(N)n1', 'Nc1cc(COc2ccc(O)cc2)cc(N)n1']. I have no problem getting a fingerprint.
It looks as if, after deleting the substructure, there are some smiles_frags that are not correct SMILES.
To prove wich SMILES in the list gives the problem you can use
QUESTION
I am fairly new to SQL and APIs so if the question is trivial I am sorry about that ...
I just learned to SELECT query user ID's in my SQL database which I map and parse to use as parameters in a GET call using searchParam.
All values in the database is 100% correct, but the API sometimes does not return certain arrays and I want to know which one is missing.
My SQL database parsed values return something like this ["10941","21707229","30827766","30918070","30924695","116669947"]
The website's API GET data array result looks something like this

QUESTION
Pointers in C is a very hard subject for me. This is part of a code from my homework and it reproduces the problem that I am having.
...ANSWER
Answered 2021-Feb-28 at 00:49The problem that you might be misunderstanding is that calling free(temp) releases the object in memory pointed to by temp - it doesn't really have anything to do with the temp variable itself. temp will be deallocated once the function returns. In fact, declaring temp itself might even be unnecessary.
QUESTION
Marvin Framework is running perfectly in my Java project in Eclipse. I have copied the whole marvin folder to the project root folder, following the readme file. All good.
Now, when setting up the same app as dynamic web project in Eclipse and try to run it on Eclipses tomcat 9, I get a HTTP Status 500 – Internal Server Error caused by java.lang.ClassNotFoundException (see 'ERROR 1'below).
It seems, in a dynamic web project the jars should be in WEB-INF/lib. When copying marvin_1.5.5.jar to WEB-INF/lib the class marvin.image.MarvinImage is found correctly (ERROR 1 disappears).
But unfortunately the Marvin image plugins are not found. I have tried to copy the whole marvin folder to WEB-INF/lib - did not work. I got another HTTP Status 500 – Internal Server Error with java.lang.NullPointerException (see 'ERROR 2' below).
I have tried to set the MarvinDefinitions.setImagePluginPath to myproject/WebContent/WEB-INF/lib/plugins/ - did not work. I got an error in the console: java.nio.file.NoSuchFileException: \myproject\WebContent\WEB-INF\lib\plugins\org.marvinproject.image.transform.scale.jar.
-> Does anyone know how to implement Marvin in a dynamic web project properly?
ERROR 1
...ANSWER
Answered 2021-Jan-28 at 05:43The problem with the way the Marvin zip distribution works is that it loads the JAR files at runtime as files. So you'll have to find out where the plugins were deployed. Retrieving a reference to the ServletContext and setting:

I have a list called transactions_clean, cleaned up from whitespace etc., look like this:
...ANSWER
Answered 2021-Jan-06 at 11:01When you iterate over your list by for item in transactions_clean: you get items for each list, so indexing them like item[1] would just give you string characters. If the order is always like customer -> sale -> thread_sold, you can do something like this:

I am trying to create a cronjob from a custom Django command.
When I run the command manually, it works perfect. Exactly what I want. The only thing is, that I want it scheduled (twice a day). But when I put the exact same command in crontab -e it doesn't work?
Any suggestions?
Crontab -e:

Answered 2020-Dec-22 at 10:47Ok, I've found the solution. The crontab was actually running (as I tought), because te log said so.
But I was using a executable in my python file, which crontab could not find. This had to do something with that crontab doesn't have PATH by default. The user shell does look in path for the executable. Crontab doesn't. You can fix this by adding at the top of your crontab:

Answered 2020-Dec-21 at 00:15You could utilize the break-inside/page-break-inside CSS property to avoid the column breaking in the middle of an li element. Both properties do the same thing but they're used in tandem here for wider browser compatibility.
