A Comparison of the Classical and a Modern Theory of Detonation
A q u i t e complete exposi t ion of what has been ca l l ed the c l a s s i c a l theory of detonat ion i s given i n t he S c i e n t i f i c American of May 1987 by W.C. Davis. However, Davis s t a t e s i n h i s repor t t h a t , "In s p i t e of t h e v a r i e t y of modern app l i ca t ions of explosives, detonat ion science has no t ye t reached maturi ty . . .," and, "Sc ien t i s t s...
متن کاملAnalysis of Multiple Choice Questions Based On Classical Test Theory
Introduction: The aim of this study was to use Classical Test Theory (CTT) software for qualitative and quantitative analysis of Multiple Choice Questions (MCQ) for Master students of health discipline. Methods: This study was carried out on two groups each including 50 undergraduate students of public health, and two groups of 50 and 26 undergraduate students of occupational health. The final...
متن کاملState of Detonation Stability Theory and Its Application to Propulsion
We present an overview of the current state of detonation stability theory and discuss its implications for propulsion. The emphasis of the review is on the exact or asymptotic treatments of detonations, including various asymptotic limits that appear in the literature. The role that instability plays in practical detonation-based propulsion is of primary importance and is largely unexplored, h...
متن کاملStudy of a Model Equation in Detonation Theory: Multidimensional Effects
Here we analyze properties of an equation that we previously proposed to model the dynamics of unstable detonation waves [A. R. Kasimov, L. M. Faria, and R. R. Rosales, Model for shock wave chaos, Phys. Rev. Lett., 110 (2013), 104104]. The equation is ut+ 1 2 ( u2 − uu 0−, t x = f ( x, u ( 0−, t )) , x ≤ 0, t > 0. It describes a detonation shock at x = 0 with the reaction zone in x < 0. We inve...
متن کاملPsychometric Properties of the Brief Form of Professor-Students Rapport Scale-based on Classical Test Theory and Item-Response Theory
Introduction: In order to improve the quality of the teaching process, it is necessary to review the professor-student rapport. The purpose of the present study was to investigate the factor structure and item-response parameters of Professor-Students Rapport Scale-Brief (PSRS-B). Methods: In a descriptive-correlation study, 497 students from Shahid Beheshti University of Medical Sciences were ...
