Growth Aspects, CPUE and Stock Size Estimation for Fish Populations of Dorudzan Reservoir, Fars Province, Iran

Knowledge of fish diversity, population data and the stock size, and calculation of the amount of proper catch are essential for a wise and sustainable management of lakes. This research reports a study on fish populations in Dorudzan reservoir, Fars Province. The fish were sampled from three stations in the late Summer and mid Spring 2015, three days each, using nylon gill nets. The mean lengt...

language learning strategies and vocabulary size of iranian efl learners

learning a second or foreign language requires the manipulation of four main skills, namely, listening, reading, speaking, and writing which lead to effective communication. it is obvious that vocabulary is an indispensible part of any communication, so without a vocabulary, no meaningful communication can take place and meaningful communication relies heavily on vocabulary. one fundamental fac...

Empirical Bayes procedure for estimating genetic distance between populations and effective population size.

We developed an empirical Bayes procedure to estimate genetic distances between populations using allele frequencies. This procedure makes it possible to describe the skewness of the genetic distance while taking full account of the uncertainty of the sample allele frequencies. Dirichlet priors of the allele frequencies are specified, and the posterior distributions of the various composite par...

Optimal Fixed-Size Controllers for Decentralized POMDPs

Solving decentralized partially observable Markov decision processes (DEC-POMDPs) is a difficult task. Exact solutions are intractable in all but the smallest problems and approximate solutions provide limited optimality guarantees. As a more principled alternative, we present a novel formulation of an optimal fixed-size solution of a DEC-POMDP as a nonlinear program. We discuss the benefits of...
