  • We consider the problem of estimating the scale parameter of the Weibull distribution based on multiply Type-II censored samples. We propose two estimators by using the approximate maximum likelihood estimation method for Weibull and extreme value distributions. The proposed estimators are compared in the sense of the mean squared error.

  • Eu$^{2+}$ doped optical fibers were developed for magneto-optical application by use of CO gas as a reduction agent during MCVD process and the Verdet constant of the Eu$^{2+}$ doped fiber was found to be -0.819[rad/T ${\cdot}$ m], which is three times larger than that of the Eu$^{3+}$ doped fiber.
