Can Science Methods Really be Taught On-Line?
In this paper, the process in which both project-based curriculum strategies and Blackboard web-based technology were utilized to develop on-line methods courses to prepare science teachers is described. A discussion of the curriculum design process includes a rationale for using project-based instruction in methods courses, along with a rationale for using Blackboard, a web-based technology, as the environment for the course. The courseās potential for creating highly qualiļ¬ed science teachers as deļ¬ned by the No Child Left Behind legislation of 2001 and the National Science Teacher Associationās Standards for Science Teacher Preparation will be explored [1]
Study concerning nonlinear mixing of radio frequency signals in steel structures Final report
Locating technique for nonlinear interference source of radio frequency signals in steel structur
Junction range finder
Electronic system locates interferences in radar reception. System utilizes well known frequency-modulated continuous-wave technique to locate objects with nonlinear impedances. FM transmitter generates signal through bandpass filter which eliminates higher order harmonics around carrier frequency
Asymptotic Properties of Approximate Bayesian Computation
Approximate Bayesian computation allows for statistical analysis in models
with intractable likelihoods. In this paper we consider the asymptotic
behaviour of the posterior distribution obtained by this method. We give
general results on the rate at which the posterior distribution concentrates on
sets containing the true parameter, its limiting shape, and the asymptotic
distribution of the posterior mean. These results hold under given rates for
the tolerance used within the method, mild regularity conditions on the summary
statistics, and a condition linked to identification of the true parameters.
Implications for practitioners are discussed.Comment: This 31 pages paper is a revised version of the paper, including
