A computationally efficient alternative for the LF model and its perceptual evaluation
نویسنده
چکیده
An alternative for the Liljencrants-Fant (LF) glottal-pulse model is presented. This alternative is derived from the Rosenberg model. Therefore, we call it the Rosenberg++ model. In the derivation use a general framework for glottal-pulse models. The Rosenberg++ model is described by the same set of T or R parameters as the LF model but has the advantage over the LF model that it is computationally more efficient. It is compared with the LF model in a psycho-acoustic experiment, from which we conclude that in a practical situation it is capable of producing synthetic speech which is perceptually equivalent to speech generated with the LF model.

Computationally Efficient Long Horizon Model Predictive Direct Current Control of DFIG Wind Turbines
Model predictive control (MPC) based methods are gaining more and more attention in power converters and electrical drives. Nevertheless, high computational burden of MPC is an obstacle for its application, especially when the prediction horizon increases extends. At the same time, increasing the prediction horizon leads to a superior response. In this paper, a long horizon MPC is proposed to c...

The continuum based approaches don’t provide the correct physics in atomic scales. On the other hand, the molecular based approaches are limited by the length and simulated process time. As an attractive alternative, this paper proposes the Fixed Interfacial Multiscale Method (FIMM) for computationally and mathematically efficient modeling of solid structures. The approach is applicable to mult...

In this research, we proposed a new metaheuristic technique for stock portfolio multi-objective optimization employing the combination of Strength Pareto Evolutionary Algorithm (SPEA), Adaptive Neuro-Fuzzy Inference System (ANFIS) and Arbitrage Pricing Theory (APT). To generate the more precise model, ANFIS has implemented to envisage long-term movement values of the Tehran Stock Exchange (TSE)...
