A substantial reduction in the grain size of aluminum alloys can be attained through severe plastic deformation (SPD) [2,3].
Then rods were subjected by rolling with a reduction of ~0.86at room temperature.
In the data presented, high angle grains boundaries (HAGBs) were defined as q³15° in misorientation and low angle grains boundaries (LAGBs) as 3°It may be indicative for decreased contribution of grain boundary sliding (GBS) to total elongation which is confirmed by a reduction in the m value with strain (Fig. 7.).

Method Analysis and interpretation of symptoms observed during the treatment of the refractive errors of the first author eyes, using light stimuli corrective lenses and predetermined movements with the eyes or head to find a scientific justification compatible with the literature data.
After many repetitions of these procedures he found a reduction in the number of superimposed circles.
The settling movement of the lens, an increase in the thickness of the lens causing a reduction of the diameter of the lens [4] Fig. 1a there is a reduction in its volume (accommodated) and Fig. 1b there is an increase in its volume (unaccommodated) this is being considered, by hypothesis, as the mechanism of forced convection transfer of nutrients (does the unaccommodated) and elimination of metabolic wastes in the lens (does the accommodated).

This is supported by mechanical strength data.
Furthermore, a more uniform distribution of unhydrated cement particles in the cement matrix, without significant depletion near aggregate surfaces, as well as a reduction of the ITZ, are reported [8].
Kim [8] found a significant reduction or even elimination of the Ca(OH)2 crystals that normally coat the aggregate surfaces and their possible replacement by C-S-H in PVAA modified mortars.
The reduction in Ca(OH)2 on aggregate surfaces probably arose from the inhibition of crystallization nucleation of calcium hydroxide by adsorbed PVAA.

Furthermore, the cost function is derived based on eight sets of data sampling, and needs very complex mathematical calculation.

Table 1 Differences in the criteria for existing and new structures Criteria Existing structures New structures Economical incremental cost of increasing the structural safety is commonly high incremental cost of increasing the structural safety is commonly lower Social may be significant due to reduction or disruption of serviceability and preservation of heritage values commonly less significant than for existing structures Sustainability in large measure existing materials are used, leading to reduction of waste commonly new materials are applied Recent reliability assessment of structures of two lateral halls of the ice-hockey stadium in Liberec, north part of Bohemia, can serve as an example of such a procedure.
It should be noted that some CEN countries apply a bigger reduction factor for existing steel structures.
A more developed procedure of the risk management could be a long-term monitoring not only of the snow but also of the actual structural behaviour including deflections, deformations or cracking by means of laser measurement devices in selected places of the stadium, and transfer of the data to computer and their evaluation with respect to specified limits.

Literature [3] studies the method of the implementation of integrated resource planning, which can bring economic efficiency and carbon reduction benefits to the electric power enterprises .Literature [4] sets up a evaluation index system of coordination degree of low carbon power grid planning, based on the combination of analytic hierarchy process and distance coordination degree model to evaluate the coordination degree of low carbon power grid planning.
Determination of the key events which impact power planning Key events influenced the development of system is that the factors play an important role in the development of the system, usually get by system analysis and on the basis of the comprehensive expert opinion and historical data.
represents the low-carbon electricity development demand: as the country gradually enhance the requirements of emission reduction targets of the electric power industry, power generation enterprises have to adopt new low-carbon electricity technology.
It can be learnt from the analysis that the operation of clean energy of wind power and low-carbon electricity technology of carbon capture makes plan one meet key events preferably, which means meeting the requirements of energy conservation and emissions reduction of electric power industry preferably.

Finally, a multi-axial fatigue life prediction model was used to predict the fatigue life with or without the corrosive environment which showed a good agreement with experimental data.
Mutombo et al [9]. investigated the corrosion fatigue behaviour of aluminum alloy 6061-T651 and found that the reduction in the fatigue life in NaCl was most likely due to the presence of pits which nucleated on second phase particles or precipitates.
(a) fitting line (b) twice error bands of model Fig. 8 Life prediction results Data of uniaxial and multiaxial tests with or without corrosive environment at pH 3 were used to fatigue life prediction.
The accuracy of prediction model can be verified by Fig. 8, where most fatigue data of aluminum alloy 6061-T6 tested in air and in corrosion lie in twice error bands.

A censor controlled the RPM of the wheel and the data was passed to a micro controller and micro controller produced PWM signals according to obtained signal.
In the second part, a power supply unit, a microcontroller, an LCD screen to see the necessary data about rpm was prepared for the control of the brake system.
The digital data is then sent to recorder of the PWM which also located in the micro controller.
• Maintenance requirements will be less than conventional system Fig. 3 The flowchart of the process of the micro controller • Needs less mechanical components which is good for cost reduction and flexibility of the design • Can be easily connected with the sensors and mechatronic system of the cars such as such as adaptive cruise control or automatic parking system

The pseudo-first-order, pseudo-second-order and intra-particle diffusion were used to fit adsorption data in the kinetic studies.
According to the data obtain, the values of RL were less than 1 and greater than 0 for all initial MB concentration indicating a favorable adsorption.
Langmuir isotherm model best represent the equilibrium adsorption experiment and pseudo-second order model provide the best correlation of the sorption data.

A large volume of selected experimental data has been collected from existing literature and then analyzed.
The new empirical model seems to perform much better when applied to the published experimental data on normal weight concrete over a wide strength range.
