Growth and reproductive biology of Capoeta damascina (Valenciennes, 1842) from a tributary of Tigris
Growth and reproductive attributes were determined for Capoeta damascina, an endemic fish species from west of Iran. A total of 147 specimens of both sexes were sampled monthly from November 2008 to October 2009. The overall sex ratio was female biased. Males were aged 0-4 years and females 0-5 years. The von Bertalanffy growth parameters were estimated as Linf=34.81 cm, k=0.27 year-1, t0=-0.65...
Six rice cultivars were crossed in half diallel design to evaluate their GCA and SCA in 2005. In the following year, parents and their progenies were grown in a randomized complete block design with three replications, and 10 traits were measured. The analysis of variance showed significant differences (p≤0.01) between cultivars. Furthermore, general combining ability (GCA) and specific combini...
It is known that the single-modal Weibull model describes well the size effect of brittle fiber tensile strength. However, some ceramic fibers have been reported that single-modal Weibull model provided biased estimation on the gauge length dependence. A hypothesis on the bias is that the density of critical defects is very small, thus, fracture probability of small gauge length samples distrib...
We present an algorithm for the inference of context-free graph grammars from examples. The algorithm builds on an earlier system for frequent substructure discovery, and is biased toward grammars that minimize description length. Grammar features include recursion, variables and relationships. We present an illustrative example, demonstrate the algorithms ability to learn in the presence of n...
