This work addresses the problem of melodic motif spotting, given a query, in Carnatic music. Melody in Carnatic music is based on the concept of raga. Melodic motifs are signature phrases which give a raga its identity. They are also the fundamental units that enable extempore elaborations of a raga. In this paper, an attempt is made to spot typical melodic motifs of a raga queried in a musical...

The most common controller in wind turbine is the blade pitch angle control in order to get the desired power. Controlling the pitch angle in wind turbines has a direct impact on the dynamic performance of the machine and fluct­uat­io­ns in the power systems. Due to constant changes in wind speed, the wind turbines are of nonlinear and multivariate system. The design of a controller that can ad...

In this paper, an interval Type-2 fuzzy logic based pitch angle controller is proposed for fixed speed wind energy system (WES) to maintain the aerodynamic power at its rated value. The pitch angle reference is generated by the proposed controller which can compensate the non-linear characteristics of the pitch angle to the wind speed. The presence of third dimension in the Type-2 fuzzy logic c...

Wind turbine preview control has recently attracted attention in the literature. This is due to significant load attenuation and power optimization benefits that can be obtained by incorporating wind preview measurements into the turbine control laws. However, the trade-offs between performance, preview time, and actuation rate limits are not well understood. This paper investigates the fundame...

This study presents a novel quadratic programming based approach to glottal inverse filtering. The proposed method aims to jointly model the effect of the vocal tract and lip radiation with a single filter whose coefficients are optimized using the quadratic programming framework. This allows the proposed method to directly estimate the glottal flow of speech, which mitigates the problem of non...

This paper examines the prosodic encoding of sentence types in Jaminjung, a language of Northern Australia. Analyses cover the description of the contours as well as a systematic acoustic analysis, comprising the measurements of F0, duration, pitch excursion and velocity for each syllable in datasets carefully selected from spontaneous speech. Results show that declaratives and imperatives rece...

We introduce the vsti-poly.cpp architecture for the Faust programming language. It provides several features that are important for practical use of Faust-generated VSTi synthesizers. We focus on the VST architecture as one that has been used traditionally and is supported by many popular tools, and add several important features: polyphony, note history and pitch-bend support. These features t...

abstractthe liquid crystal director distribution is determined for a confined chiral nematic slab. the molecular director distribution of the field-controlled chiral nematic slab is directly calculated. the director profiles for the tilt and the twist angles, under different applied fields, are calculated in the slab with weak boundary conditions. then, the dependence of the threshold field on ...
