Midwives are among the trainer's of family planning programs who have direct contact with the group  of women in reproductive ages. This survey was carried out on all married midwives of Kerman city ( n=57) in July 1994, in order to determine their knowledge, attitude and practice about family planning using questionnaire prepared by investigators. Among the respondents: 40.3℅ were technicia...

PURPOSE To evaluate different strategies for proton lung treatment planning based on four-dimensional CT (4DCT) scans. METHODS AND MATERIALS Twelve cases, involving only gross tumor volumes (GTV), were evaluated. Single image sets of (1) maximum intensity projection (MIP3) of end inhale (EI), middle exhale (ME) and end exhale (EE) images; (2) average intensity projection (AVG) of all phase im...

PURPOSE To build a knowledge-based model of liver cancer for Auto-Planning, a function in Pinnacle, which is used as an automated inverse intensity modulated radiation therapy (IMRT) planning system. METHODS AND MATERIALS Fifty Tomotherapy patients were enrolled to extract the dose-volume histograms (DVHs) information and construct the protocol for Auto-Planning model. Twenty more patients we...

1. introduction language teachers frequently observe a gap between their students' potential competence and their performance in the class. anderson (1993) attributes this to the fact that human has a limited processing capacity and is not able to attend to various aspects of a task simultaneously. this limitation causes l2 learners not to be able to focus on both meaning and form at the same t...

This paper presents a simulation analysis on the effects of robust master production scheduling. Up to now, relatively highly aggregated planning models for robust master production scheduling were regarded and the realizability of the planning results was not considered. This paper analyses a more detailed model for master production scheduling than in previous works. The evaluation of the pla...

This paper reports the effect of the step-size (learning rate parameter) on the performance of the backpropgation algorithm. Backpropagation algorithm (BP) is used to train multilayer neural network. BP algorithm is the generalized form of the least mean square (LMS) algorithm. In this proposed backpropagation algorithm different learning rate parameter are used in different layer. The learning...

For all $a,b>0$, the following two optimal inequalities are presented: $H^{alpha}(a,b)L^{1-alpha}(a,b)geq M_{frac{1-4alpha}{3}}(a,b)$ for $alphain[frac{1}{4},1)$, and $ H^{alpha}(a,b)L^{1-alpha}(a,b)leq M_{frac{1-4alpha}{3}}(a,b)$ for $alphain(0,frac{3sqrt{5}-5}{40}]$. Here, $H(a,b)$, $L(a,b)$, and $M_p(a,b)$ denote the harmonic, logarithmic, and power means of order $p$ of two positive numbers...
