Due to increasing sales figures focus is on the reduction of cycle times.
Measured data sets were processed and analysed for each individual bore.
None of the described special entry strategies (non-constant feedrate) resulted in significant reductions of the medium deflection.

It has been evidenced that NH3-SCR (Selective Catalyst Reduction) technology is one of the effective methods to reduce the NOx emission from diesel engine [1, 2].
In the experiment, the mixture of C3H6/NO/N2/O2 with different concentrations can be obtained by inputting wanted data on the panel of the PCGM.
When the initial concentration of C3H6 is 700×10-6 and the discharge power is 80W, the NO2/NOx ratio can reach 52.3%, but it is unfavorable for the selective catalyst reduction of NOx.

All silicon devices showed the typical behaviour, already reported in [2, 6] with an oscillation in the leakage current monitoring combined with a reduction of the bend-off-voltage in the intermediate measurements.
An early voltage drop can be seen after the first 50 h of testing usually attributed to redistribution of mobile ions [12] and a second, more pronounced reduction after 500 h of test time due to aluminium corrosion and delamination of insulating layers.
This is in line with the previously published data sets and therefore, standard testing needs to be improved for SiC-devices.

In order to control of the plant was carried out without problems, you should start with the introduction of basic data - Kanban to the algorithm.
Initially, these requirements apply to reduction of the prices of products, thus indirectly their manufacturing costs.
In this case, is preferred the standardization of production and the reduction of operation is not bringing added value (assortment, technology).

If DAF is greater than 1.5, reduction of the overhead crane capacity or consideration of damping will be necessary.
Structural model were later verified using deflection data obtained from static load testing by adjusting the value of spring constant k over the column locations along the crane runway sections as illustrated in Figure 5.
The possibilities for remedial actions include strengthening, repair, intensified monitoring, load reduction, and demolition.

The following questions were taken into account in designing the concrete mixture: minimization of cement consumption to reduce energy consumption and mixture cost, guarantee of workability and reduction of defects due to the collapse of the longitudinal ribs, as well as surface quality [17, 18].
The reduction of cement consumption was 100kg/m3.
The research data makes it possible to see the potential of further research on the selection and optimization of decorative concretes’ composition.

Microhardness data of the milled powders were measured by an indentation technique, using Vickers Hardness Tester type (Shimadzu Microhardness), at a load of 25gm.
Also, it is observed that the crystalline sizes of all the investigated powder mixtures decreased with very high rate of reduction to nano-sized crystals after milling for 150hr, Fig. 2, and with a lower rate of reduction further on.

This article takes two aluminum-tin alloys of ordinary casting and semi-continuous casting as the research object, reveals the influence of casting method, deformation temperature, deformation amount, and heat treatment temperature on microstructure evolution, and provides data support for the improvement of aluminum-tin alloy processing technology.
When rolling at 140℃, the effects of rolling reductions of 20%, 40%, 60%, and 80% on the morphology of Sn phase were studied, as shown in Fig. 5.
However, the amount of Sn phase is significantly reduced, because the annealing temperature exceeds the melting point of the Sn phase too much, and Sn overflows from the alloy in the form of sweat. 5cm 5cm (b) (a) 5cm 5cm (d) (c) Fig. 4 The photos of ordinary casting ingot were rolled at (a) 200°C, (b) 160°C, (c) 140°C and (d) room temperature (b) (a) (d) (c) Fig. 5 SEM of rolling reductions of (a) 20%, (b) 40%, (c) 60%, and (d) 80% at 140℃ of ordinary casting ingot at L-S (b) (a) Fig. 6 SEM photos of the annealed sheet at 220 ℃: (a) S-T direction and (b) L-S (b) (a) Fig. 7 SEM photos of the annealed sheet at 250 ℃: (a) S-T direction and (b) L-S direction (b) (a) Fig. 8 SEM photos of the annealed sheet at 280 ℃: (a) S-T direction and (b) L-S direction Microstructure evolution of AlSn20Cu alloy prepared by semi-continuous casting during rolling and heat treatment process The microstructure evolution of ordinary

Figure 2 The schematic view of the experimental equipment: 1 engine, 2 dynamometer, 3 dynamometer controller, 4 high-speed data acquisition board, 5 pressure transducer, 6 optical encoder,7 ECU, 8 computer. [9] For this experimental investigation, a special category of ECU (Engine Control Unit), which is programmable in order to achieve different working parameters, has been used.
The increase in the engine load effects the reduction of concentration levels of toluene primarily as a result of enabled favorable conditions for combustion.
Increasing the engine speed, engine load and the air content in the supply air-fuel mixture effects the reduction of concentration levels of toluene in the mixture of exhaust gases, which indicates possibility of controlling the emission characteristics by varying the appropriate operating parameters of the engine.

The calculated results and measured data are shown in Fig.5.The dark curve is measured data, and the light curve is calculated values.
In addition, we also tested and verified these analyses by discussed the symbol contrast measured data of cross direction raster scanning.
To test and verify the upper analytical result, the symbol contrast measured data of cross direction raster scanning were used.
The measured data are show in Fig. 2 (b).
