Classical and Bayesian estimation of parameters on the generalized exponentiated gamma distribution

  In this paper, we offer generalized exponentiated gamma distribution. We consider the maximum likelihood and Bayesian estimators of unknown parameters and propose Markov chain Monte Carlo (MCMC) method to generate samples from the posterior distribution. The mean square error of estimations is computed and comparisons are made using Monte Carlo simulation.   Key words: Maximum...

Ring characteristics of 95-year old Japanese cedar plantation trees grown in Taiwan

  The ring characteristics of 95 year old Japanese cedar plantation trees grown in Taiwan were explored. Significant differences in the average ring width (RW), earlywood width, latewood width, ring density (RD), earlywood density, latewood density, highest density, lowest density, and latewood percentage were observed among three tree diameter classes and three radial stages of ring numbers. The RW parameters...

Failure load of corner joints, which are reinforced with glass-fiber fabric in case-type furniture

  In this study, the failure load of L-type corner joints, which are reinforced with glass-fiber fabric, of the case-type furniture have been analyzed experimentally and statistically in laminated medium-density fiberboard (LMDF) material. The failure loads of corner joints have been analyzed experimentally under compression and tension loads. Dowels (D), dowel + glass fiber composite layer from the outside...

Many exact solutions for nonlinear dynamics of DNA model using the generalized Riccati equation mapping method

  The objective of this paper is to apply the generalized Riccati equation mapping method for constructing the exact traveling wave solutions of a nonlinear partial differential equation describing the dynamics of DNA modeling. This model consists of two long elastic homogeneous strands connected with each other by an elastic membrane. Hyperbolic and trigonometric function solutions of this model are obtained....
