A System for Assessing the Knowledge and Skills of Students in Computer Programming
This article presents the author’s experience in
teaching programming to university students in first and second year. The system for assessing the knowledge and skills of students is an essential part of teaching. It aims not only to assess students, but also to help improving their knowledge. The importance and difficulty of Computer Programming requires specific and unconventional approach to this activity. The article discusses all three elements of ongoing assessment (tests for knowledge, homeworks, and practical programming skills), as well as the rules for final exams and final assessment
Bulgarian Folk Songs in a Digital Library
The paper presents the main results of an ongoing project aimed at the development of technologies for digitization of Bulgarian folk music and building a heterogeneous digital library with Bulgarian folk songs presented with their music, notes and text. An initial digitization and preservation of the Bulgarian cultural heritage starts by means of digitization and insertion into the library of over 1000 songs that were recorded and written down during the 60s and 70s of XX century. Also we present a full text search engine in a collection of lyrics (text of songs) and coded notes (symbolic melody). Some perspectives for future projects are also discussed
Information Technology for Preserving the Bulgarian Folklore Heritage
Folk songs are an important and essential part of the Bulgarian cultural heritage. Following the traditions of the
20th century in publishing Bulgarian folk songs, we prepared
the book “Folk Songs from Thrace” [3] with scores and lyrics
recorded from original performances in the 60s and 80s of the last century. We created a digital library of over 1200 songs, which provides access to songs via full-text search engine. The data sources are stored using advanced information technology to encode texts, notes and sound. Traditional indexes and bookmarks for the book are also developed using our software
Numerical Solutions of ODEs using Volterra Series
We propose a numerical approach for solving systems of nonautonomous ordinary di®erential equations under suitable assumptions. This approach is based on expansion of the solutions by Volterra series and allows to estimate the accuracy of the approximation. Also we can solve some ordinary di®erential equations for which the classical numerical methods fail
