LcssAlgorithm

This project enables to study the problem of finding similarity between trajectories (trajectory similarity problem) which is a known problem in the field of Data Mining. The algorithm called to deploy and solves the above problem is the LCSS(Longest Common Subsequence). Each orbit is described by a sequence geographical points (latidute, longitude). Each record dataset that we are given represents a path of a taxi that has taken place in the city of Beijing. Each line of the file contains the following separated by commas: taxi id, timestamp, latitude, longitude.

Vm_Manager

This work provides a program that translates logical and physical addresses for a room-sized virtual address 216 = 65.536 bytes (Virtual Memory Manager). The program reads from a file containing logical addresses and, using a TLB (16 seats) and a page table (1 layer), translates each logical address in its corresponding physical address and outputs the value of the byte, stored in the translated physical address. Finally it reads a file containing several integers - logical addresses. The logical addresses are organized as follows: (1) page number and 8 bits (2) offset of the page within 8 bits.

Unix_Debugger

The aim of this work is to familiarize us with system programming in Unix, namely the creation of processes and communication between them with pipelining. We are implementing a very basic debugger using ptrace system call, which will inform the user of the system calls executed by the monitored program. We are also implementing a bash script which automates the entire process of using the picodb targeted program, extracting measurements from the exit.
