Their goals was to achieve a high discounts of insurances by creation of conditions for reduction of enterprise risks and by acceptance of preventive measures in relation to identified potential danger.
Control of the possible failure creation and with this connected risk, is the process of decision making for encompassment and/or reduction of risk, or realization of decision and its enforcement including repeated evaluation of consequences with the use of the results of risk appraisal as input data [3].
There are several classes or levels of criticality depending on risks and reduction of system serviceability and also on the probability of frequency [4].
Change of the concept – for elimination of fault causes or for reduction of the fault importance 2.
By the help of analysis we get the possibility to realize the prevention of these risks or their reduction.

Mathematical Model
The goal of optimal planning on capacitor in power distribution network is the installation location and compensation capacity of fixed parallel capacitor, which makes total loss reduction benefits maximum in every static period, that means power distribution network loss being minimum.
The maximum loss reduction benefits are taken as objective function during the planning period, namely
a) Input original data, taboo step is 4, the maximum iterative steps is 10 for the same continuous optimal solution.
A 34 nodes distribution system is optimized, whose data is taken from literature [7].

(3) Imperialist Competitive Algorithm (ICA)
ICA is an optimization method based on imperialist competition that introduced by Atashpaz-Gargari[9].The algorithm for ICA is summarized in following steps:
Step 1: The input data is inserted in the program and important parameters of ICA are defined.
The load and line data are taken from [1].

As compared with the data for submicrometer-grain-sized material with d ≈ 350 nm,
nano-crystallization of ZrO2 ceramics less than d ≈ 90 nm can improve σf by a factor of 2.0-2.5.
The fracture strength σf monotonously increases with a reduction of grain size.
(bottom) 500nm (a) 500nm (a) Crack 200nm (c) Crack 200nm (c) toughness KIC or a reduction of the radius of critical flaw a.
This result is consistent well with the data that the transformation strengthening does not work for fine grained material; transformability of the t-ZrO2 phase is reduced by a decrease in the grain size [19-22].
According to the relation between σf and a in Eq. 3, on the other hand, a reduction of residual flaw size can also be effective in increasing σf [20].

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.

The total area of Si-Hx related bands

Any imperfections or disorder in the crystalline specimens invariably results in such a reduction.
The logarithm of peak-to-peak (pp) height of third joint density of states (3JDOS) at E1 shows a systematic reduction as a function of current density (see Fig. 3 inset) [8,9].
It may be noted in Table 1 (layer 3) that with the thickness reduction [from 77(9) to 50.2(7) nm], there is also a substantial reduction in the void fraction [from 97.13 to 35.2] hence the actual quantity of SiO2 is not reflected by the thickness alone.
Hence, the quantity of a-SiO2 is actually increasing with current density as evident from FTIR data.
