Design process is a key process in forming of product’s cost and if we notify to total design we will see all of the effective parameters in design activities. Design process is contented design planning, design inputs, design outputs, design review, design verification, design validation and design changes. This approach will help us to identify the cost parameters for managing, controlling an...

the main function of rural areas in the third world is the agricultural function which is crucially important because of its great effects on employment, moderating income and poverty, food security and self-efficacy. this article studies the role of agriculture (as an independent variable) in rural development (related variable) of miyankangi district in sistan. the method of the study was des...

Infinitely divisible random vector without Gaussian component admits representations of shot noise series. Due to possible slow convergence of the series, they have not been investigated as a device for Monte Carlo simulation. In this paper, we investigate the structure of shot noise series representations from a simulation point of view and discuss the effectiveness of quasi-Monte Carlo method...

Sufficient dimension reduction has been extensively explored in the context of independent and identically distributed data. In this article we generalize sufficient dimension reduction to longitudinal data and propose an estimating equation approach to estimating the central mean subspace. The proposed method accounts for the covariance structure within each subject and improves estimation eff...

In a text categorization model using an artificial neural network as the text classifier, scalability is poor if the neural network is trained using the raw feature space since textural data has a very high-dimension feature space. We proposed and compared four dimensionality reduction techniques to reduce the feature space into an input space of much lower dimension for the neural network clas...

background: although hemodialysis has a therapeutic effect on esrd, but these patients encounter many physical, psychological, and social stress full factors that lead to a decrease in their quality of life (qol). one of the factors that are effective on increasing of qol is self care ability. review of literature demonstrates that there have been done a few studies on different aspects of qol ...

analyses and investigations on river flow behavior are major issues in design, operation and studies related to water engineering. thus, recently the application of chaos theory and new techniques, such as chaos theory, has been considered in hydrology and water resources due to relevant innovations and ability. this paper compares the performance of chaos theory with anfis model and discusses ...

Advection-dispersion equation is solved in numerically by using combinations of differential quadrature method (DQM) and various time integration techniques covering some explicit or implicit single and multi step methods. Two different initial boundary value problems modeling conservative and nonconservative transports of some substance represented by initial data are chosen as test problems. ...

Let $x$ and $y$ be two distinct vertices in a connected graph $G$. The $x,y$-location of a vertex $w$ is the ordered pair of distances from $w$ to $x$ and $y$, that is, the ordered pair $(d(x,w), d(y,w))$. A set of vertices $W$ in $G$ is $x,y$-located if any two vertices in $W$ have distinct $x,y$-location.A set $W$ of vertices in $G$ is 2-located if it is $x,y$-located, for some distinct...
