this study determines the value of linkage analysis using six rflp markers for carrier detection and prenatal diagnosis in familial dmd/bmd cases and their family members for the first time in the iranian population. we studied the dystrophin gene in 33 unrelated patients with clinical diagnosis of dmd or bmd. subsequently, we determined the rate of heterozygosity for six intragenic rflp marker...

Optical eigenvalue transmission is a promising technique to overcome Kerr nonlinear limits in optical communication systems. The associated with the Schrödinger equation invariant during fiber-based dispersive transmission. However, effect of carrier frequency offset (CFO) induces an shift presence CFO for digitally coherent receivers. estimation method using eigenvalues capable achieving highl...

A new methodology of frequency syntonization using a global positioning system (GPS) carrier phase double differences is presented. The proposed scheme can achieve the traceability of frequency dissemination and obtain the very high frequency stability in the short term, as well as in the long term. The GPS receivers used in our system were elaborately modified in order to estimate the frequenc...

The general set of HCI and Educational principles are considered and a classification system constructed. A frequency analysis of principles is used to obtain the most significant set. Metrics are devised to provide objective measures of these principles and a consistent testing regime devised. These principles are used to analyse Blackboard and Moodle.
