Gender separation is a largely encountered in the natural systems that allows the preservation of the genetic diversity in a species. In this paper, we want to analyse the mechanism by which this reproduction mode may have evolved and the way it in uences the evolution of a population toward an optimal individual.

Speaker attributed variability are undesirable in speaker independent speech recognition systems. The gender of the speaker is one of the influential sources of this variability. Common speech recognition systems tuned to the ensemble statistics over many speakers to compensate the inherent variability of speech signal. In this paper we will separate the datasets based on the gender to build ge...

This report presents a model for simulating various reproduction modes and types restrictions from nature with the genetic algorithms. We consider three reproduction modes, which are self-fertilizing, hermaphrodite excluding self fertilization, and with two differentiated gender types (male and female). We start with a model in which the reproduction mode evolves along with the rest of the geno...

attachment of children to their parents and their separation are two important growth processes which are summoned up in teens again and become more important. the present research tends to find out either the processes of attachment and separation among girls and boys take place in different ways or gender can affect the relationship between these two processes. to this end 300 students of the...

In developing countries, whereas the urban bus network is a major part of public transportation system, it is necessary to try to find the best design and routing for bus network. Optimum design of school bus routes is very important. Non-optimal solutions for this problem may increase traveling time, fuel consumption, and depreciation rate of the fleet. A new bus routing problem is presented i...

in our country, school bus routes are determined by experiments of driver without considering the scientific optimum route and location. traversing additional routes will always result an increase in vehicle movements and fuel consumption and enormous costs. hence, this paper will study the school bus routing in tehran considering special students and a model will be presented to minimize trave...

The twentieth century can be considered the century of gender approaches. From extremist and one-sided movements to moderate and neutral schools of thought about gender, which have surrounded the last century and all of them had originated in achieving gender justice, but each has taken a different approach as a different definition of equity. The curriculum is no exception to this rule. The pu...

According to life history theory, physiological and ecological traits and parameters influence an individual's life history and thus, ultimately, its lifespan. Mating and reproduction are costly activities, and in a variety of model organisms, a negative correlation of longevity and reproductive effort has been demonstrated. We are employing the annual killifish Nothobranchius furzeri as a vert...

Perception of a target voice in the presence of a competing talker, of same or different gender as the target, was investigated in cochlear implant users, in implant-alone and bimodal (acoustic hearing in the non-implanted ear) conditions. Recordings of two male and two female talkers acted as targets and maskers, to investigate whether bimodal benefit increased for different compared to same g...
