Quotient probabilistic normed spaces and completeness results
We introduce the concept of quotient in PN spaces and give some examples. We
prove some theorems with regard to the completeness of a quotient.Comment: 10 page
A Cross Sectional Study of Iranian Women and Sex Preference for Children
Background: Children sex preferences may have significant effects in fertility behavior which is an influential component of population dynamics and could control the population size, structure, and composition. One of the core concerns of researches and policy makers is to study these determinants.Objectives: The main objective of this study is to investigate Iranian women’s sex preference and its highly influential factors through applying Classification & Regression Trees algorithm as a practical classification method.Materials: A cross-sectional study during 2014 was conducted to collect demographical data of 1250 Iranian women in age 15-49. To classify sex preferences for children, age, educational level, place of residence, and difference number of siblings for women, were nominated as predictors.Results: 71 percentages of women’s sex preference have been classified correctly (the accuracy of the model=0.71). In extracted decision tree, women's age, educational level and difference number of siblings were significant. One of the vital results indicated that educated Iranian women in different age cohorts are in favor of having girls.Conclusions: Classification & Regression Trees is an effective and easy to interpret non-parametric method which builds classification tree for predicting dependent variables
Efisiensi Produktifitas Wakaf Tunai (Wakaf Uang) Dalam Pemberdayaan Ekonomi Di Indonesia
This article aims to analyze the waqf if it is managed productively. Commonly, the existence of waqf in Indonesia is used for the mosque, school, farm, and orphanages. Thus, the existence of cash waqf is productive if it can be a solution for the community to improve the economy of the people as a form of solidarity that becomes an instrument contributed to the welfare of societ
On the Intuitionistic fuzzy topological (metric and normed) spaces
In this paper, we define precompact set in intuitionistic fuzzy metric spaces
and prove that any subset of an intuitionistic fuzzy metric space is compact if
and only if it is precompact and complete. Also we define topologically
complete intuitionistic fuzzy metrizable spaces and prove that any set in a complete intuitionistic fuzzy metric spaces is a topologically
complete intuitionistic fuzzy metrizable space and vice versa. Finally, we
define intuitionistic fuzzy normed spaces and fuzzy boundedness for linear
operators and so we prove that every finite dimensional intuitionistic fuzzy
normed space is complete.Comment: 16 page
Agent-based Modeling and Simulation of Human Muscle For Development of Software to Analyze the Human Gait
In this research, we are about to present an agentbased model of human muscle
which can be used in analysis of human movement. As the model is designed based
on the physiological structure of the muscle, The simulation calculations would
be natural, and also, It can be possible to analyze human movement using
reverse engineering methods. The model is also a suitable choice to be used in
modern prostheses, because the calculation of the model is less than other
machine learning models such as artificial neural network algorithms and It
makes our algorithm battery-friendly. We will also devise a method that can
calculate the intensity of human muscle during gait cycle using a reverse
engineering solution. The algorithm called Boots is different from some
optimization methods, so It would be able to compute the activities of both
agonist and antagonist muscles in a joint. As a consequence, By having an
agent-based model of human muscle and Boots algorithm, We would be capable to
develop software that can calculate the nervous stimulation of human's lower
body muscle based on the angular displacement during gait cycle without using
painful methods like electromyography. By developing the application as
open-source software, We are hopeful to help researchers and physicians who are
studying in medical and biomechanical fields.Comment: 14 pages, 12 figure
