Where can i find the Ubuntu Core CPU and Memory Scheduling algorithms?

I am a Computer Science student. In the subject of Operating Systems, we analyze throughout the year different topics related to Modern Operating Systems, such as methods
like CPU Scheduling (like Round Robin), Memory Scheduling, Security, etc. As part of a mandatory report, students have to collect information on different Operating Systems that were assigned to us.
Ubuntu Core was assigned to me. Therefore, I would like to know where you could find information regarding the CPU Scheduling, Memory Scheduling and the File System used by this Operating System. I have searched on my own but could not find much information.
Any information or help is welcome.
Thank you in advance and sorry for my bad english
