All this machines contaminate radio environment around them and make serious obstacles for WiFi data exchange.
Analyzing the curve presented in this figure we can notice that data transfer decreases four times in distance of 50 meters.
All data interchange between computer and AGV were done by this AP.
As a final effect we can observe stable (but not so high) data transfer rate.
It means that next data frames were supplied by different paths (not only straight way).

Electrode metal powders are generally synthesized by the wet reduction process [1-2], chemical
vapor deposition method [3] and spray dry method [4].
In this study, Ni powders were prepared by the reduction of hydrazine of Ni salts from diethanolamine (DEA) solvent.
Hydrazine hydrate (N2H4⋅H2O) was used as reducing agent and the reduction was allowed to proceed at 180~240 °C for 0~40 minutes.
XRD data revealed the characteristics of nickel crystalline as shown in Fig. 2. 10 20 30 40 50 60 70 80 (c) (b) (a) 2-Theta Intensity (a.u

This leads to the reduction at low frequencies and the increase at high frequencies.
The feasibility and accuracy of Tam and Auriault’s theory and MGBK method are assessed by experimental data. 2.
The above pictures show a systematic reduction in core length with increasing chevron inward bend angle in data sets (core breakdown initiation moves forward about 3D).
Conclusion Study of jet noise reduction on separated exhaust system using chevron nozzles are presented in this paper.
The comparison between prediction results and experiment data come to the conclusion that the far field noise spectra predicted by Tam and Auriault’s jet noise prediction theory and MGBK theory are within the acceptable accuracy.

The results demonstrate that switching the operation of an office building HVAC system from CV to VPF will significantly enhance energy savings and CO2 reduction.
The office building selected for this energy-saving and CO2 reduction study is located in central Taiwan; it is rectangular with a foot-print of 33.5 m (length) by 33.2 m (width).
Each set of data is the average value of three successive monitoring data.
Significant CO2 reduction is observed in the VPF system as compared with the CV system.
The accumulated power consumption increases from 21,757 to 468,299 kWh (data not shown), and the reduction of accumulated CO2 emission increases from 0 to 44,186 kg/year (The emission factor for electricity = 0.623 kg CO2/kwh) for the VPF chilled water system.

The so-called shear strength reduction method is for an ideal elastic-plastic finite element system and is such a process, in which the shear strength parameters of the sliding mass are gradually decreased by a varying reduction coefficient, until the system achieves an unstable state and the finite element static analysis is not convergence, and the strength reduction factor at the situation is the safety factor we want [4, 5].
Where, F is reduction coefficient or safety factor.
Through the test a lot of data were obtained.
The foundation parameters are from geological exploration data, and they are listed in Fig.3.
The calculation model for strength reduction method is shown in Fig.3 (The grade of side slope was determined as 1:1.5.

Abstract.
Thus, 3D laser scanning was used to acquire geometric feature data, including the length, width, height of unstable rock masses, controlled structural plane, and cutting depth of posterior-margin joints, and to plot the sections of the unstable rock masses (Fig. 2).
Since the saturated cohesion and internal friction angle of unstable rock mass are inaccessible, we adopted similar strata for analogy, and referred to the regional empirical data: 0.21 MPa, 29.8°; the geometric dimensions of the unstable rock masses are showed in Fig. 2.
According to SRM, the slope stability safety factor is defined as the reduction degree of a soil-rock body strength parameter when the slope reaches critical failure, or namely the ratio of actual strength to critical-failure strength of soil-rock body, or namely the reciprocal of the reduction factor [6].
