This paper presents a methodology implementation of a turn-key training system for music (singing voice). The implementation took place with Max/Msp development software. Initially we create a small corpus of anthems for testing purposes by recording four(4) small hymns. Each hymn is been performed three(3) times from the same chanter. The reason of that repetition answers the purpose of finding the...
Item Response Theory (IRT) provides the accepted framework for examining student responses to individual test items so as to assess their quality. Moreover, IRT proves especially valuable in both improving items, which will be reused in future tests, and eliminating the ambiguous or misleading ones. However, to ensure all IRT parameters are correctly estimated, every single item needs to be tested...
This paper presents a simple timing analysis of an IEEE 802.11b independent basic service set (ad-hoc) network, considering streaming video traffic. The paper starts with a theoretical approach on the timing factors which govern the functionality of IEEE 802.11b wireless networks supporting streaming video traffic. Furthermore, the total video frame transmission delay is determined and its influencing...
Enhancing the e-Learning systems with reputation, a commonly used notion in e-Commerce systems, adds value to the resource. In this paper a RDF-based e-Learning framework that is based on reputation metadata and educational standards is proposed. Morever, the model and the retrieval algorithm of a proper recommendation system are described. This system exploits reputation and description metadata...
Internet over satellite is an emerging facet of communications enabling users to have access to the Internet over high speed satellite links. However, new requirements should be satisfied by the involved protocols in order to fully utilize the available network resources. This paper discusses the possible mitigations that can be applied to the Transmission Control Protocol over satellite links. Furthermore,...
