In most privative approaches to melodic structure, the only phonological operations deemed possible are those involving the linking and delinking of primes. However, within an Element Theory model where no independent ATR prime is recognized, this restriction must be relaxed in order to accommodate cases of tongue root harmony. In response, we propose a view of melodic structure in which every ...

In this paper, we aim to analyze the performance of some variants of the harmony search (HS) metaheuristic when solving systems of nonlinear equations through the global optimization of an appropriate merit function. The HS metaheuristic draws its inspiration from an artistic process, the improvisation process of musicians seeking a wonderful harmony. A new differential best HS algorithm, based...

Music scholars have been studying tonal harmony intensively for centuries, yielding numerous theories and models. Unfortunately, a large number of these theories are formulated in a rather informal fashion and lack mathematical precision. In this article we present HarmTrace, a functional model of Western tonal harmony that builds on well-known theories of tonal harmony. In contrast to other ap...

On a strictly phonological level, vowel harmony is perhaps the best known type of non-adjacent dependency. Vowel harmony restricts the co-occurrence of vowels, regardless of the number of intervening consonants, according to agreement of specific feature or features within a word, a word and its affixes, or sometimes even across word boundaries (van der Hulst & van der Weijer 1995). Mongolian, ...

In this paper we propose a new set of harmony features for automatic emotion recognition from speech signals. They are based on the psychoacoustic harmony perception known from music theory. Starting from the estimated pitch contour of an utterance, we calculate the circular autocorrelation of the pitch histogram on the logarithmic semitone scale. It measures the occurrence of different two-pit...

This paper presents the use of the improved harmony search method for solving economic load dispatch problems. The harmony search method mimics a jazz improvisation process by musicians in order to seek a fantastic state of harmony. To assess the searching performance of the proposed method, a six-unit thermal generating system acquired from the standard IEEE 30-bus test system was challenged. ...

The phonology and clinically induced learning patterns of a female child with a phonological delay (age 4;11) were examined from the analytical perspective of Optimality Theory. The analysis revealed that a Consonant Harmony error pattern affected alveolar stops from two different sources-from underlying lexical representations and from representations derived by an interacting error pattern of...

In 1956, we decided at the Budapest University of Technology and Economics to start a large-scale experiment on color harmony. The experiments and the processing of the experimental results have been completed in 2006. These experiments, described in this article, form a study of how much are people, participating in the experiment, influenced by their own personal color preference in judging t...

This study first reviews fuzzy random Portfolio selection theory and describes the concept of portfolio optimization model as a useful instrument for helping finance practitioners and researchers. Second, this paper specifically aims at applying possibility-based models for transforming the fuzzy random variables to the linear programming. The harmony search algorithm approaches to resolve the ...

Harmony search is a new heuristic optimization algorithm. Comparing with other algorithms, this algorithm has very strong robustness and can be easily operated. Combining with the features of harmony search, an improved simulated annealing algorithm is proposed in this paper. It can improve the speed of annealing. The initial state of simulated annealing and new solutions are generated by harmo...
