This paper presents a two‐stage model that calculates tonal context as a continuous function in time. The model is capable of processing acoustical polyphonic inputs. The first stage is a simple note recogniser that produces pitch‐class note output corresponding to the acoustical input. A bank of leaky integrators constitute the second stage. The integration rates and saturation limits of these integrators vary with each musical event according to the relations among input notes and the candidates of tonal centre. User controllable parameters enable musical memory time span control. The output of the model is the tonal context vector retaining normalised values of the leaky integrators with each integrator holding the strength value of a specific tonal centre.


A tool for comparison of piano performances
Bora, U; Tufan, S; Bilgen, Semih (Informa UK Limited, 2000-01-01)
In this paper a tool designed for analyzing music performance is introduced. The tool interprets a performance of a piano piece and lists the "errors" it finds by comparing the performance to a pre-recorded expert performance of that piece, utilizing MIDI files. It is primarily intended to be used in piano education. Examples of applications as well as the architecture and design of the tool are given.
A variational multiscale constitutive model for nanocrystalline materials
Gürses, Ercan (Elsevier BV, 2011-03-01)
This paper presents a variational multi-scale constitutive model in the finite deformation regime capable of capturing the mechanical behavior of nanocrystalline (nc) fcc metals. The nc-material is modeled as a two-phase material consisting of a grain interior phase and a grain boundary effected zone (GBAZ). A rate-independent isotropic porous plasticity model is employed to describe the GBAZ, whereas a crystal-plasticity model which accounts for the transition from partial dislocation to full dislocation m...
A neuro-fuzzy MAR algorithm for temporal rule-based systems
Sisman, NA; Alpaslan, Ferda Nur; Akman, V (1999-08-04)
This paper introduces a new neuro-fuzzy model for constructing a knowledge base of temporal fuzzy rules obtained by the Multivariate Autoregressive (MAR) algorithm. The model described contains two main parts, one for fuzzy-rule extraction and one for the storage of extracted rules. The fuzzy rules are obtained from time series data using the MAR algorithm. Time-series analysis basically deals with tabular data. It interprets the data obtained for making inferences about future behavior of the variables. Fu...
A frequency domain boundary element formulation for dynamic interaction problems in poroviscoelastic media
Argeso, Hakan; Mengi, Yalcin (2014-02-01)
A unified formulation is presented, based on the boundary element method, to perform the interaction analysis for the problems involving poroviscoelastic media. The proposed formulation permits the evaluation of all the elements of impedance and input motion matrices at a single step in terms of system matrices of boundary element method without solving any special problem, such as, unit displacement or load problem, as required by conventional methods. It further eliminates the complicated procedure and th...
A Novel Alternating Cell Directions Implicit Method for the Solution of Incompressible Navier Stokes Equations on Unstructured Grids
Bas, O.; ÇETE, ALİ RUHŞEN; Mengi, S.; Tuncer, İsmail Hakkı; Kaynak, U. (2017-01-01)
In this paper, A Novel Alternating Cell Direction Implicit Method (ACDI) is researched which allows implementation of fast line implicit methods on quadrilateral unstructured meshes. In ACDI method, designated alternating cell directions are taken along a series of contiguous cells within the unstructured grid domain and used as implicit lines similar to Line Gauss Seidel Method (LGS). ACDI method applied earlier for the solution of potential flows is extended for the solution of the incompressible Navier-S...
