In this paper, an algorithm for index reduction of differential algebraic equations (DAE) is proposed. Pantelides has already been proposed as purpose. This conventional succeeded in reducing the calculation time required reduction. However, there exist some DAE systems whose cannot be reduced correctly with because it uses sufficient condition to reduce index. We propose modify solution obtain...

We present a model and propose an approach to compute an approximate solution of Fully Fuzzy Linear System $(FFLS)$ of equations in which all the components of the coefficient matrix are either nonnegative or nonpositive. First, in discussing an $FFLS$ with a nonnegative coefficient matrix, we consider an equivalent $FFLS$ by using an appropriate permutation to simplify fuzzy multiplications. T...

Six-Sigma has some measures which measure performance characteristics related to a process. In most of the traditional methods, exact estimation is used to assess these measures and to utilize them in practice. In this paper, to estimate some of these measures, including Defects per Million Opportunities (DPMO), Defects per Opportunity (DPO), Defects per unit (DPU) and Yield, a new algorithm ba...

Acoustic characteristics of speech signals differ with gender due to physiological differences of the glottis and the vocal tract. Previous research [1] showed that adding the voice-source related measuresH∗ 1 −H∗ 2 andH∗ 1 −A3 improved gender classification accuracy compared to using only the fundamental frequency (F0) and formant frequencies. H∗ i refers to the i–th source spectral harmonic m...

In stochastic (dynamic) traffic assignment (DTA), route choice (RC) formulations with implicit set require less memory than their explicit counterparts. To compute turn probabilities, however, a topological ordering of the nodes is needed, which negatively impacts stability convergence and consistency equilibrium. This paper formulates general framework for RC module efficient DTA (ESDTA) witho...

An efficient assignment and scheduling of tasks is one of the key elements in effective utilization of heterogeneous multiprocessor systems. The task scheduling problem has been proven to be NP-hard is the reason why we used meta-heuristic methods for finding a suboptimal schedule. In this paper we proposed a new approach using TRIZ (specially 40 inventive principles). The basic idea of thi...
