Schematic prehistoric images of ancient animals and humans (caves of Spain and France) So, many peoples with the image of spirals and circles associated the sun, light, or any astral symbols, with a triangle - mountains, plowed land, feminine, and a wavy line - traditionally designated water.
Important in this context is the professional training and literacy of specialists who work creatively in this field - a deep knowledge of the historical roots of iconic culture, semiotics, the role of symbols and signs in the history of mankind, the significance and use of their archaism in modern times.
It is important to define the tasks and the specifics of professional work in the design of communicative systems, create a structural classification of urban spaces for the systemic solution of functional and composite visualization tasks by pictographic means of important communicative zones, literate designation of pedestrian and traffic intersections and other functional structures.

The empirical work on this topic consists primarily of surveys of purchasing professionals.
Most of experts suggest that the following aspects be taken into account when considering the factors in the AHP system: ①{TTP}9312 Environmental Quality: Evaluate environmental performance during the whole product life cycle, that is, the environmental impact of products ,in the whole process from the obtaining of raw materials, production, sales, use to recycle which include pollutant emissions in production ,various resources’ consumption rate (including water, wood, petroleum and minerals), waste emissions, waste disposal and recycling, and the recovery rates of packaging and so on. ②{TTP}9313 Environmental Management: the number of environmental disputes, the establishment of environmental management institution and system, emission of pollutants not reaching the standard and pay of sewage charges, participation in the management of pollution control, approval of the relevant authentication system (such as ISO14000). ③{TTP}9314 Investment in Environment protection: Costs of

However, these tests, if carried out on site by site workers, may give inadequate results due to lack of professional knowledge and proper training [2].
The artificial neural networks (ANNs) are a recently popular nonparametric approach to estimate the water quality parameters.
Water-to-cement ratio: W/C = (W+SP) / (C) Water-to-binder ratio: W/B = (W+SP)/ (C+FL+SL) Water-to-solid ratio: W/S = (W+SP)/(C+FL+SL+CA+FA) Total aggregate-to-binder ratio: TA/B = (CA+FA) / (C+FL+SL) Therefore, in this approach, slump of concrete is a nonlinear function of these eleven input variables described above.
Statistical properties of components Components Minimum Maximum Cement (kg/m3) 137.0 374.0 Fly ash (kg/m3) 0.0 193.0 Blast furnace slag (kg/m3) 0.0 260.0 Water (kg/m3) 160.0 240.0 Superplasticizer (kg/m3) 4.4 19.0 Coarse aggregate (kg/m3) 708.0 1049.9 Fine aggregate (kg/m3) 640.6 902.0 Water-to-cement ratio (W/C) 0.5 1.736 Water-to-binder ratio (W/B) 0.3 0.678 Water-to-solid ratio (W/S) 0.075 0.125 Total aggregate-to-binder ratio (TA/B) 2.363 5.562 Slump (cm) 0.0 29.0 Data set.
The highly nonlinear equation obtained using BPN helps us realize the mixture mechanisms in a transparent way, containing only three significant input variables including fly ash (FL), water (W), and water-to-binder ratio (W/B).

Heat collecting pipes in a closed loop, containing water (with a little antifreeze) are used to extract this stored energy, which can then be used to provide space heating and domestic hot water.

However, the financial statements provided by the business data itself, there may be water, so users need to report through the quality of accounting information in the context of such adjustment or re-compute the data in the financial statements, and then use data mining technology to analyze financial statements.
Data mining alone computer or software is unable to complete this task. the more is the need to rely on professional judgments professionals.

Such as the cost paid for staff training on safety knowledge, the cost of professional safety management setup, as well as the cost of lots of safety articles, rectification cost for hidden danger.

This shows that the training is effective and accurate. 3) Results analysis We can see from the case study: A3 (potency dimension of government supervision), A5 (schedule development), A9 (level of transparency of safety information), A11 professional safety management setup), A14 (selection of equipment and process and their management), A20 (measures of safety award and punishment), such six short-term behavior have significant impact on short-term behavior in construction safety management.

And its professional production was high-strength corrugated paper; daily production was 249.73 t in 2012.
It was shown that some indexes such as comprehensive energy consumption, waste water discharge, COD, BOD5 and SS discharge, and repeat utilization rate of industrial water had not been achieved to level third standard from table 1.
Net department on high-speed paper machine usually needed the maximum fresh water in paper machine.
The advanced and suitable spray equipment could save lots of fresh water.
It could save 1.5 million tons of fresh water and 24300 tons of steam a year.

Second, is the pore structure, to achieve more than 95% of the obturator structure, in order to ensure the heat insulation function at the same time, to reduce the water absorption ratio.
At present, several domestic large-scale professional energy-saving building materials enterprises were developed on the above indexes, such as New Construction Materials (Shanghai) Company Limited and Ji'nan Shengquan Group Company Limited.
These companies based on the modification of phenolic resin foam and process optimization, the sheet production has high obturator rate, low water absorption rate, has good toughness, good flame retardant, low smoke emission characteristics.
The production has solved the traditional phenolic foam poor toughness, easy to slag, high water absorption and shortcomings, and at very high temperatures and mechanical loads, deformation and creep are small, ensuring product integrity of structure and dimensional stability.
With waterproof moisture characteristic, phenolic foam has good obturator structure, low water absorption, water vapor permeability ability, in the cold does not occur dew.

An S-shaped water channel is set up on the top of the dike model to simulate the leak water channel.
The water source is at the far end and water run through the top of dike in the channel.
During the experiment, the water flow in the channel are increase from 0.01m3/s to 1 m3/s .With the soil and rock flushing away, the channel became wider and finally became a big erosional fossa.
Erosional fossa Water Flow Channel Fig.2 Points Cloud of Dike Model After the Flood Event Fig.1 Points Cloud of Dike Model Before the Flood Event Points Clouds Combine.
Real Works is professional point cloud processing software.

And, we always choose input variables according to professional knowledge.
