متن کاملKey Estimation Using Circle of Fifths
This paper presents a novel key estimation method of sound sources based on the music theory known as "circle of fifths". We firstly overview music theory and formulate the musical key analysis by vector operations. In detail, we separate music sources into small pieces and calculate FFT-based chroma vectors. They are converted to tonality vectors and COF (circle-of-fifth) vectors are calculate...
متن کاملبررسی ویژگی‌های بالینی و بافت‌شناسی Consecutive Exotropia
هدف: بررسی ویژگی‌های بالینی، هیستوپاتولوژی و جمعیت‌شناختی Consecutive Exotropia و تعیین رابطه مقدار- پاسخ در این بیماران. روش پژوهش: بیماران دارای Consecutive Exotropia که در فاصله زمانی شهریور 1393 تا اردیبهشت 1394 به بیمارستان فارابی تهران مراجعه کرده بودند، وارد مطالعه شدند. پس از معاینه چشم‌پزشکی کامل و تعیین میزان انحراف دور و نزدیک، تمامی بیماران دارای Forced Duction Test منفی، تحت جراحی ...
متن کاملConsecutive holes
A hole in a graph is an induced subgraph which is a cycle of length at least four. We prove that for all ν > 0, every triangle-free graph with sufficiently large chromatic number contains holes of ν consecutive lengths. In particular, this implies two well-known conjectures of Gyárfás [3], namely that every triangle-free graph with sufficiently large chromatic number has a hole of length at lea...
متن کاملSelf-organizing Neural Sets and the Perceptual Origin of the Circle of Fifths
One of the more surprising results of the use of artiicial neural networks in the analysis of acoustic perceptions is the regularity of dispositions, on a Kohonen self-organizing map, of chord images: in fact these images clearly show the bent to spontaneously dispose themselves along closed, circular patterns reminiscent of the circle of fths. In this paper we rstly reproduce these results and...
