Numerical modeling procedure The procedure for coupled dynamic mechanic-al and water simulations is divided into two steps: first, the stage should be led to a mechanical equilibrium and steady-state flow state.
The Power Station, has a designed installed capacity of 5.85 million kilowatts, storage capacity of 237.4 ×108 m3, the width and height of the crest of 18 m and 261.5 m (from elevation 560 m to el. 821.5m) respectively and the length along the top of the dam is 605 m, slope ratio of upstream is 1:1.9, slope ratio of downstream is 1:1.8.

Introduction El-Halim et al. [1,2] investigated Ni-Co and Ni-Co-Tl powder electrodeposition from the electrolyte containing ammonium sulfate and boric acid.
It is also noteworthy that the morphology of Ni-Co powders presented in the paper of ElHalim et al. [1] is completely different than the one presented in this work.

This conclusion didn’t agree with the opinion of EL-Jazairi et al [5] and Hansson et al [6].
EL-Jazairi et al thought that nitrite ions didn’t enter into the reaction involved in producing the anode, but reacted with the resulting products of the anode, thus it could not affect the size of the anode [5].
Hansson et al didn’t consider the change of anodic curve resulted from nitrite.

Chu et al., (2009) suggested a Lab-on-a-Chip device to focus the particles at the center of the channel.
Demierre et al., (2007) proposed a microfluidic device using lateral dielectrophoresis to focus and continuously separate cells [1].
The present microfluidic device, similar to that of Demierre el al., can focus particles eliminating the use of sheath flow and pumps.
The problem space and boundary conditions for the electrical and thermal problem are modeled similarly to the work by Green el al. [5], and the lateral microfluidic microelectrodes structure is shown schematically in Fig.1.
Such a sample preparation follows the process proposed by Doh et al. [7].In order to obtain the optimal condition of separation; we measure DEP response of viable and nonviable yeast cells using test devices in terms of the medium conductivity and the electric fields frequency before the particles focusing experiment.

It is based on work carried out on two fibrous materials, a barkcloth material (Rwawiire et al. 2017) and a hemp wool (El-Sawalhi et al. 2016).
We are aware that the fibres are not perfectly parallel (Lei et al., 2018) and that their orientation can have an influence on the thermal conductivity (El Hachem et al. 2017), but in this paper, we take this assumption that remains acceptable in a first approximation.

According to Koren et al. [6] Modularity, integrability, and diagnosibility reduce the reconfiguration time and effort while customization, scalability and convertibility reduce the cost of maintenance, the cost of the system and consequently the cost of production.
Then intracellular machine layout and inter cell layout are performed using the method presented by Ahi et al. [8] and then the process can be planned using the technique presented by Ciurana et al. [9] in which a model for integrating process planning and production and control in machining process was worked out.
