A modification for differential evolution method is developed to solve the problem of synthesizing a fuzzy system with optimal parameters. This allows you handle both integer and continuous variables, making it possible any mixed integer-continuous problems, including parametric synthesis control system, as contains types The main idea change procedure generating initial population, well introd...

the purpose of this study is estimation of daily value at risk (var) for total index of tehran stock exchange using parametric, nonparametric and semi-parametric approaches. conditional and unconditional coverage backtesting are used for evaluating the accuracy of calculated var and also to compare the performance of mentioned approaches. in most cases, based on backtesting statistics results, ...

The decomposition of audio signals into perceptually meaningful modulation components is highly desirable for the development of new audio effects on the one hand and as a building block for future efficient audio compression algorithms on the other hand. In the past, there has always been a distinction between parametric coding methods and waveform coding: While waveform coding methods scale e...

We consider the synthesis of distributed implementations for specifications in parameterized temporal logics such as PROMPT–LTL, which extends LTL by temporal operators equipped with parameters that bound their scope. For single process synthesis, it is well-established that such parametric extensions do not increase worst-case complexities. For synchronous distributed systems, we show that, de...

This paper presents an optimization of the Arabic database and a prototype for real-time speech synthesis. Statistical parametric speech synthesis is a relatively new approach to speech synthesis. Hidden Markov model based speech synthesis, the techniques in this approach, has been demonstrated to be very effective in synthesizing high quality, natural and expressive speech. This work modified ...

We show that a common language can be used to unify the description of parametrically coupled circuits—parametric amplifiers, frequency converters, and parametric nonreciprocal devices—with band-pass filter impedance matching networks. This enables one readily adapt network synthesis methods from microwave engineering in design devices having prescribed transfer characteristics, e.g., gain, ban...
