This thesis is concerned with the particular problem of composing 5th species two voice strict counterpoint exercises for a given Cantus firmus. The melody (Contrapunctus) has been represented in the computer as a Lisp List. A class of Lisp functions, called 'normal characteristic functions' has been defined and several lemmata and theorems related to the mathematical properties of these functions have been proved. Normal characteristic functions have then been utilized for recognizing and generating certain classes of melodies (Lisp lists) which obey given rules of counterpoint. The implementation of a computer program which generates strict counterpoint exercices using this theory has been described. In this implementation a full set of academically acceptable rules of counterpoint has ben used, in addition to new rules propounded by the author. The computer outputs and some transcriptions of computer composed melodies in conventional music notation have been included in the text of the thesis. The results have been found to be very promosing.

Convergence of text and reader: a study of textual strategies and the formation of configurative meaning in selected works of fiction Shadi, Mehran; Sönmez, Margaret Jeanne M.; Department of English Literature (2018) In this study, first, the foundational developments in the domains of linguistics, philosophy of language and literary theory that have led to a transformation of the concept of the reader are reviewed closely. Then, to understand the nature of literary responses, an Interactionalist Model of Readership (IMR) is proposed to explore the two sides of the reader-text interaction and the nature of the final product of the reading act. Using various examples, the interaction between the text and the reader is, t...
Long-term potentiation in teaching vocabulary in foreign language Bilgin, Zikri; Doyran, Feyza; Department of English Language Teaching (2010) This thesis mainly intends to study and reach some conclusions related to major challenges concerning vocabulary teaching or learning, how vocabulary teaching can be improved, findings obtained from the studies in order to reach that purpose and to what extend the suggested alternative vocabulary techniques are effective. It is also aimed to outline the basic insights of the mind, storage, and retrieval from the literature involving linguistics and language teaching. Based on above mentioned background know...
On the possibility of a parallelism between Wittgenstein’s understanding of language and music Durukan, Burcu; Turan, Şeref Halil; Department of Philosophy (2019) In my thesis, my main aim is to examine the parallelism between Ludwig Wittgenstein’s understanding of language and music. I will explain my ideas about the similarity between language and music with the linguistic concepts of Wittgenstein. Then, I will compare music and language in terms of their resemblance regarding the issue of meaning. Lastly, I will conclude that musical understanding is shaped through being a part of a particular social context just as in the case of understanding a language, and the...
Stable controller design for T-S fuzzy systems based on Lie algebras Banks, SP; Gurkan, E; Erkmen, İsmet (Elsevier BV, 2005-12-01) In this paper, we study the stability of fuzzy control systems of Takagi-Sugeno-(T-S) type based on the classical theory of Lie algebras. T-S fuzzy systems are used to model nonlinear systems as a set of rules with consequents of the type x(t) = A(l)x (t) + B(l)u (t). We conduct the stability analysis of such T-S fuzzy models using the Lie algebra LA generated by the A(l) matrices of these subsystems for each rule in the rule base. We first develop our approach of stability analysis for a commuting algebra ...
A Video-Based Analysis of Rhythmic Accuracy and Maintenance in Junior Tennis Players Söğüt, Mustafa; Akar, Gözde (2017-01-01) This study mainly focused on the video-based analysis of two parameters of rhythmic ability: rhythmic accuracy (RA) and rhythmic maintenance (RM). The effects of tempo on these parameters were also investigated. The participants were junior competitive tennis players (n= 41, age= 13.46 1.64 years). The video-based analysis system that relies entirely on the features extracted automatically from the audiovisual data was used to determine the RA and RM performances of the participants for the tempos of 44 and...
