basket-application

Simple Basket Application

compilers-project

Creation of a parser and translator to Java, MiniJava semantic check using Java, JavaCC and JTB visitors and generation of intermediate Code from MiniJava to LLVM.

computer-security-projects

A project touching system security. The first party addresses buffer overflow attacks, the second TLS attacks, the third rainbow tables against password hashes and the fourth has to do with website protection against vulnerabilities (XSS, CSRF, RFI, SQL injection, phishing etc.).

data-mining-projects

A program in Python that was tasked to analyse a large amount of data and then classify tweets according to their sentiment to positive, neutral and negative. The data were cleared, stemmed and the most common words were removed and after that they were vectorised using a number of methods, also including word embeddings (an algorithm we created ourselves) and then classified using the KNN and SVM algorithms.

drummachine

A simple drum machine application, developed using React.

home-rental-web-application

Online marketplace created using Java - JSF, JavaScript, MySQL, HTML5/CSS and Apache HTTP Server

ngrams-detection

Program in C++ which reads and stores ngrams (sorted) in a tree structure and then detects and prints the ngrams asked using binary search, a hashtable and a bloom filter while also performing algorithms like compression and topk on the structure.

node-asn1

Contains parsers and serializers for ASN.1 (currently BER only)

parallel-programming

Program in C computing the convolution of an image (read as an array). The image is first split into smaller blocks and then, using Message Passing Interface (MPI), the convolution of these subarrays is computed in parallel, each in a different core, designed to minimize time and increase efficiency. The number of cores and the size of the image are dynamic.

system-programming-projects

Server-client programs in C that utilize data structures(graphs), hashtables (dynamic hashtables, using buckets), threads, signals and pipes. Project one models a server(bank)-client(user) application that traces and performs money transfers between user accounts. The second project models a boardpost where each user can post something to it and project 3 is a more advanced version of project 1 also using sockets.
