During the last three decades, especially 1980's, language learning specialists have been busy  discovering the nature of language learning strategies, describing them, and formulating their relationships with other language learning factors. In line with these studies, the field of translation studies has undergone a complete revolution in terms of its perspective toward its research prioritie...

Background: Osteoporosis knowledge test is a comprehensive questionnaire that evaluates risk factors, nutrition and exercise recommendations, as well as general subjects such as bone evolution, diagnosis, and osteoporosis treatment. The aim of this study was to determine the psychometric characteristics of the revised version of osteoporosis knowledge test (OKT) in Iranian adolescent population...

Suppose S is a finite generalized quadrangle (GQ) of order (s, t), s 6= 1 6= t, and suppose that L is a line of S. A symmetry about L is an automorphism of the GQ which fixes every line of S meeting L (including L). A line is called an axis of symmetry if there is a full group of symmetries of size s about this line, and a point of a generalized quadrangle is a translation point if every line t...

We give a characterization of translation ovoids of flock generalized quadrangles. Then we prove that, if q = 2e , each elation generalized quadrangle defined by a flock has a large class of translation ovoids which arise from semifields of dimension two over their left nucleus. Finally, we give some examples when q is odd. © 2003 Elsevier Ltd. All rights reserved. MSC (2000): Primary 51E12; Se...

 This paper discusses models for manufacturing systems that are based on generalized stochastic Petri nets and on Markov decision processes. We employ generalized stochastic Petri nets to model manufacturing processes with high degree of uncertainty due to the human operator behavior. We extend the usual generalized stochastic Petri nets by allowing imprecision about probabilities to be explic...
