Suresh [14] analyzed the effects of lot sizes, set-up reduction factors, cell size, and inter-cell movements in a simulation experiment comparing JS and CM.
The simulation results showed that CM could outperform JS under certain circumstances especially small batch sizes, large set-up time reduction, and large cell size.
Shafer and Meredith [12] conducted research using actual data to compare the performance of JS and CM.
The proposed DSS receives online results from simulator and identifies the possibility for improving performance from real-time simulation data exchange (SDX).
The simulation results illustrate that with limited material handling capacity and opportunities for setup time reduction, MCM can outperform JS and CM.

A reduction of more than 90% in the drying time was identified.
Statistical analysis: All data were collected at least in triplicate.
The WVP data presented in Table 2 presented no statistical difference (p <0.05) between the evaluated films, which makes it possible to infer that, within the submitted parameters, there is no interference of the heating temperature in the permeability of the biopolymeryc films.
Conclusion The changes in temperature and drying time showed a favorable response in the reduction of the contact angle, which shows that it affected the roughness characteristics, also visualized by increasing tensile strength of the dry films at the controlled temperature, which affected by decreasing the roughness.
In general, it can be observed a reduction of more than 90% of the drying time, making its synthesis and large-scale use more attractive.

LA was established mainly by Beremin group for solution of tasks associated with statistical size effect, scatter of experimental data and prediction of temperature dependence for fracture toughness [1, 2].
Temperature dependence of the main mechanical characteristics of iron: is a fracture stress, is yield stress, is reduction in area Figure 2.
The value of average strain in cross-section of notched specimen was estimated as follows: , (4) where - reduction in cross-sectional area, is a diameter of neck after fracture, - is initial diameter of a specimen.
For our RPV 15Ch2NMFAA steel the similar analysis is based on the standard CT specimen data.
The results are very close to literature findings, m parameter for 2 parametric local approach was determined to be 7.4, for 3 parametric local approach and data in temperature range <-90, -130> oC the shape parameter gains the value m = 1.9 (at = 1260 MPa).

Key word: span-thickness ratio, reinforced concrete frame beams, arching action
Abstract: This paper mainly deals with the influence of the variety of span-thickness ratio of beams on arching action of reinforced concrete frame beams through trial experiment research and theory analyzes.By experimental study and theoretical analysis,limit carrying capacity of reinforced concrete frame beams can be enhanced largely owing to arching action.The larger span-thickness ratio of beams is,the lower arching action of reinforced concrete frame beams and limit carrying capacity is,but the reduction is disproportionate.

The peak shifts toward lower Gate voltage as temperature increases, in agreement with the threshold voltage reduction at higher temperature.
The experimental data are obtained using the setup of Fig.1a, the capacitance is measured between Gate and Source terminals, while a DC bias is applied to Drain terminal, VDS.
The distribution is considered uniform along all the SiC/SiO2 interface [16], since no calibration is performed on experimental data.
This result confirms the behavior found in the experimental data.
Moreover, this result agrees with the threshold voltage reduction with increasing temperature.

The data of the base year is the basis for the planning.
Generally speaking, the planning often chooses the closest year with relatively complete data and information.
The task of the control and planning of the total amount of marine pollutant is specifically embodied as below: The government needs to have a comprehensive grasp of the basic data of the nature, society and economic development of the targeted sea area and the region.
In the process of collecting and sorting the data, systematic and comprehensive investigation, analysis and evaluation need to be made on the status quo of the environmental quality and the source of pollution of this area.
The country thoroughly implement the scientific outlook on development, adhere to the principle of combining the control of increment and reduction, strengthen pollution reduction and control work by readjusting industrial structure and optimizing industrial layout.

Cross-section point data of clypeus of dung beetle Copris ochus Motschulsky have been extracted from the 3D scanning data of the dung beetle.
CorelTRACE software to get the characteristic curve data can be utilized.
This method can reduce noise data and interference.
Both lower and higher threshold values would result in interference and noise data.
