Introduction: C. elegans neural network is a good sample for neural networks studies, because its structural details are completely determined. In this study, the virtual neural network of this worm that was proposed by Suzuki et al. for control of movement was reconstructed by adding newly discovered synapses for each of these network neurons. These synapses are newly discovered in the actu...

A profile hidden Markov model (PHMM) is widely used in assigning protein sequences to protein families. In this model, the hidden states only depend on the previous hidden state and observations are independent given hidden states. In other words, in the PHMM, only the information of the left side of a hidden state is considered. However, it makes sense that considering the information of the b...

the solutions of mathematical models for the estimation of the kinetic, and biokinetic parameters of naphthalene, anthracene and pyrene during degradation in surface and subsurface soils are presented in this work. the models were developed using the twin concepts of rate-determining step and steady-state approximation method. they described the biodegradation of single and a mixture of polycy...

the johor strait is an estuarine system located on the coast of the state of johor in malaysia.the western part of johor strait is a shallow estuarine located between causeway and pulai river. ahydrodynamic model was calibrated based on the environmental fluid dynamic code (efdc) from 4th to 17th of october, 2009. in this calibration, the efdc hydrodynamic model was configured to simulate time ...

background: healthcare authorities, in all around the world, are faced with resources limitations and limitless needs of citizens. therefore, optimal resources allocation, particularly in the health sector and emergency system, seems to be of great importance. the present study aimed to determine the optimality rate of patients' distribution to hospitals by emergency stations based on the trans...

due to the importance of the role of land use changes on runoff changes, several studies have taken place to develop models with simulating land use changes. in this study, the l-thia model was used for estimating the runoff made by land use changes in chalousrud watershed. results of runoff modeling using l-thia model showed that runoff depth increased from 422.98mm to 809.168mm during 1984 to...

In industries, Preventive Maintenance (PM) is not a new practice to minimise the sudden breakdown of production machine. PM will be performed at predetermine intervals to provide a balance between failure cost and component utilisation (aging). However, most of PM interval is based on experience or original equipment manufacturer (OEM) recommendations. Consequently, the benefits from PM are not...

in this work, we have calculated the joule-thomson inversion curve of two important associating fluids, namely water and methanol, from the saft equation of state. comparisons with the available experimental data, for water and methanol indicate that this molecular based equation of state gives good prediction of the low temperature branch; but, unfortunately, due to lack of isenthalpic data fo...
