CE-QUAL-W2 is widely used for simulating hydrodynamics and water quality of the aquatic environments. Currently, model calibration mainly based on trial error, therefore it subject to knowledge experience users. The Particle Swarm Optimization (PSO) algorithm has been tested automatic CE-QUAL-W2, but an issue prematurely converging a local optimum. In this study, we proposed Improved Global-Bes...

Abstract One of the essential issues in quality management water resources is determination level eutrophication and dissolved oxygen dam reservoirs other bodies. It possible to study changes concentration using qualitative models. In this study, CE-QUAL-W2, a two-dimensional model hydrodynamics capable predicting behavior aquatic ecosystems, has been used simulate eutrophication. As case Yamch...

Algal blooms have been reported in some tributary bays since the initial impoundment of Three Gorges Reservoir, which has seriously affected water ecology and drinking safety. Hydrodynamics plays a crucial role algae growth. The recent numerical models hydrodynamics quality are effective to identify effects on phytoplankton find potential strategies for controlling algal blooms. In this study, ...

Let V be a real unitary space and let W1, W2 be subspaces of V . The functor W1 + W2 yields a strict subspace of V and is defined as follows: (Def. 1) The carrier of W1 + W2 = {v + u; v ranges over vectors of V , u ranges over vectors of V : v ∈ W1 ∧ u ∈ W2}. Let V be a real unitary space and let W1, W2 be subspaces of V . The functor W1 ∩ W2 yields a strict subspace of V and is defined by: (De...

Previous studies revealed that the recessive allele of the W2 locus generated purple-blue color and high vacuolar pH of flower petals in soybean. The location of W2 gene was reportedly close to simple sequence repeat marker Satt318 in molecular linkage group B2. We used information from the soybean genome to clone a candidate gene for W2. An MYB transcription factor gene belonging to G20 group ...

In classical growth analysis, relative growth rate (RGR) is calculated as RGR = (ln W2 - ln W1)/(t2 - t1), where W1 and W2 are plant dry weights at times t1 and t2. Since RGR is usually calculated using destructive harvests of several individuals, an obvious approach is to substitute W1 and W2 with sample means W1 and W2. Here we demonstrate that this approach yields a biased estimate of RGR wh...
