Such approach improves the exergy of tested materials [4] – PCC and PC, as it enables the reduction of use of limited natural resources, the utilization of the wastes remaining after production process and – at the same time – the lowering the material cost of C-PC, thus improving sustainability.
The technical characteristic of applied polyester resin according to producers data is given in Table 1.
Similar results were obtained when substituting 25% of coarse aggregate with filler type “III” – almost 50% reduction of mechanical strength (though applying larger amounts of this filler into polymer concrete affected strength less than it was in case of filler type “II” – strength reduction of 60 -80%).
However in case PCC of higher plastic filler content (40% of coarse aggregate) the greater decreases in flexural strength was observed: for PCC with filler “IV” a 25% flexural strength reduction was noted, for PCC with filler “V” – a 38% reduction was noted and for PCC with filler “VI” – a 44% reduction was noted.
Modification of PCC by the maximal considered plastic filler content (40%) caused effects as following: modification by filler “IV” caused a 20% compressive strength reduction, modification by filler “V” caused a 28% compressive strength reduction and modification by filler “VI” caused a 31% compressive strength reduction.

Therefore is possible to get a reduction in the excitation current to obtain the same magnetic flux density.
This reduction in the excitation current is due to the core length in an OWC is smallest than CWC and this produces the reluctance reduction of the core.
This reduction on the slope in both core configurations was analyzed and compared.
The reductions of eddy current losses and excitation currents depend of the proportions of the mix.

Next the influence of the amount of data available for parameterization is investigated by determining how much experimental data can be neglected without increasing the deviation of StrucSim [8].
In addition, the correlation between the amount of data available for characterization and the model accuracy can be studied by disregarding specific amounts of the data during parameterization.
Fig. 6 shows that using about 50 % of the data does not increase the deviation.
StrucSim model is based on full data (line) and reduced data (dots).

In this paper, the damping force loci of a twin tube shock absorber were estimated by using the empirical data.
The relationship between the piston velocity and the damping force were estimated by using the empirical data of four different conditions of coil spring turns.
Also the relationship between the coil spring turns and the damping force were estimated by using the empirical data of four different piston velocities.
In case of the needs of the smoother ride, the vibration reduction should be one of the overcoming troubles for the stability of the vehicle.
The same experiments for each of different conditions were processed in five times and then the values obtained from the five experiments were averaged to be applied to the empirical data for the estimation of the loci of the damping force variations.

For analaysis in GRA, datas available should be pre-processed into some quantitative datas for the subsequent process of normalizing.
In preprocessing of raw data for comparison, the original data sequence is converted into a decimal sequance that lies between zero to one.
Zero implies no data information and one implies data with full information.
If the data should be of the condition “Higher-the-better”, then original data sequence should be normalized as, (1) where xoi (k) is original raw data sequence, x∗i (k) is data sequence after data preprocessing, max xoi (k) is maximum value of original sequence, and min xoi (k) is the minimum value of original sequence.
When the output response should be “Smaller-the-better” condition, then the data sequence is normalied as: (2) Principal Component Analysis.

Nevertheless, communicating or integrating information that is from different sources is challenging, no to mention the variances in sampling data, data structure, and methods of collecting data[93].
Moreso, there are several disciplines behind the collection of data during each of the life-cycle processes, and synergizing the collected data and the knowledge into a dependable system is another daunting task[94]. 10.3 Absence of Process Safety Decision Making System For the large-scale manufacturing industry, one of the best approaches to minimized costs and increased benefits is by producing en-mass.

In order to analyze deposits model, the methods adopted includes that arrangement of existing geophysical and geochemical exploration results, familiar with the former research results, and based on the collection of data, studying comprehensively the geological characteristics of deposits, discussing the deposits genesis.
It found that metal mineral combination about the Cu(Au) ore body is pyrite + chalcopyrite + molybdenite(less) + magnetite (less), and transit to a peripheral area of pyrite + chalcopyrite + magnetite, to sphalerite + chalcopyrite + pyrite + lead ore (less) from inside to outside in porphyries body in Xiongcun by studying, which reflected the rock permeability and diffusion about the hydrothermal system of ore-bearing porphyry, all this caused by different types of mineralization process due to temperature and pressure reduction.
Deficiency is a lack of data, it is very difficult to distinguish which kind of exploration method played a key role, the division includes both the exploration methods and working train of thought, prospecting cognition.
Research methods: ①arrangement of existing geophysical and geochemical exploration results, familiar with the former research results. based on the collection of data, studying comprehensively the geological characteristics of deposits, methods adopted the field observation and indoor optical slice identification, studying synthetically geological features in the area, which including the regional geological background, the ore types, ore fabric and material composition, metallogenic elements combination, and Wall rock alteration characteristics, and so on. ③ studying and discussing the deposits genesis about Xiongcun Cu (Au) deposits, summarizing metallogenic regularity and Prospecting model.
It is divided into 6 categories: ①Geological mapping method (77%).②Geochemical methods (69%).③geophysical method (47%).④theory model of prospecting method (24%).⑤Remote sensing method (12%).⑥Drilling method (11%). the newly discovered deposits in main metallogenic belt in Tibet since the geology survey beginning (1999) that It is difficult to completely identify which kinds of exploration methods played a key role due to the lack of systematic data.
