CovIDetect

CovIDetect is a dashboard application for universities that aims to facilitate the process of managing covid cases and provide statistical insight on attandance rates as well as covid cases.

Functionalities

The app provides 3 main functionalities:

• Room Visualization

• Update Covid Status (Manually)

• Statistical Analysis

Room Visualization

This functionality provides the user with a visualization of a room and its covid/possible cases.

The user can select a room, the date at which they wish to see the state of the room and the hours that a lecture occured (HourSpan).

They can also click on the Student ID List button and see all the students that were sitting as well as their health status (covid case, possible case, healthy).

Update Covid Status (Manually)

This functionality provides the user with the ability to manually update a student's health status to a covid case.

The user can enter a student's ID and pick the date at which the student was tested and turned out to positive.

The system will automatically update the status of the student and set the possible cases appropriately, two days before the date, for all rooms at which the student may have sat.

Statistical Analysis

This functionality provides the user with the ability to visualize statistical data of attendance rates and covid cases.

This data can be shown:

‣ Yearly

‣ Monthly

‣ Daily

‣ By Hour

‣ By Professor

The user can select a specific range of dates (From, To) for which they wish to see statistical data for.

They can also select the data category (Attendance Rates, Covid Case Stats) as well as an additional statistical method (in this version, only standard deviation is available).

Setup

This version of the software is available for all platforms that have Java installed.

Requirements

This project requires:

• Java SE Development Kit 17.0.1 and above which can be found here: https://www.oracle.com/java/technologies/javase/jdk17-archive-downloads.html

• JavaFX which can be found here: https://openjfx.io/

No additional files are needed to run the app.

However, an academic email is required to log in (@uom.edu.gr, @uom.gr in this case).

In case there are problems with the academic email showing up as non existing (problem with the free email verification api (https://mailboxlayer.com/) or the user does not have an academic email, they can use this email: [email protected]

Running the app

In the jarfile folder, there is a CovIDetect.jar file which is all what's needed.

• Note that the folders and files of the app during execution are created at the same path that the .jar file is, so it is advised that the .jar be put in a folder.

Running in Windows:

java -jar -Xmx280M CovIDetect.jar

Running in Linux:

java -jar -Xmx280M -Djdk.gtk.version=2 CovIDetect-Linux.jar

will execute the app and is all that is needed.

The extra argument -Xmx280M is needed due to the memory increasing over every Service that is executed.

The JVM, while considering some objects eligible for garbage collection, doesn't give back the memory to the OS as it does not deem it necessary (probably because they are Services and it thinks that they might be used again). No "OutOfMemoryError" occured using the extra max heap size argument

Importing project on IDE
