This assumption is conservative because it considers the possibility that not all farmers will deem to use this system preferring other disposal systems and/or treatment, even in anticipation of any periodic reductions of the production of wastewater, or finally of an abnormally low yield of biogas from fermentation.
Through data provided by the town of Albanella we have defined approximately 1800 inhabitants the users unavailable.
Shown below (Table 1) are the data relating to the production and the actual amount fed into the grid, expecting 8,400 hours of operation per year and assuming the following unit revenues: -Average price of electricity for sale to the grid € 0.28 / kW-h; -Heat Energy Transfer price € 0.10 / kW-h.
Being equal heat, it reduces air pollution, especially with great benefit in terms of reduction of greenhouse gas emissions.

On the basis of the data of the above calculation, engineering hydraulic cylinder HSG*01-φ40/φ22 is selected.
And the data is transmitted to the controller, as shown in Fig.9 [5].
The system adopts photoelectric encoder as location of initial position,The bending mold returns to the initial position in order to eliminate the accumulated error after bending every time.Pulse encoder and mechanical gear are coaxially installed, the output signal is proportional to the speed,it shows the actual operating position of pipe bender. when we rotate encoder to turn a pulse, the displacement mechanism actually occurred can be converted by the mechanical transmission ratio, called the pulse equivalent displacement.The actual value of the high speed counter is multiplied by the pulse equivalent displacement, their product is the actual displacement mechanism.Here we adopt the counter strategies,the counter reaches the preset value, which is close to finishing set value of the reduction,PLC let motor reduce speed through the reduction amount in advance.When the pipe length reaches the set value, the hydraulic system is controlled to let pipe bender brake to stop by the PLC.The

This model is a blind recognition in no error, and the amount of data for analysis will dramatically increase with code length valuation expansion which results in few practical significances.
Reference [2] estimates code length according to the weight distribution, and then gains generator matrix through the improved matrix reduction.
This method avoids the complex matrix reduction arithmetic.
This is a memoryless channel, that is to say, these mistakes are produced when data sequences transmit are not related to each other.

Methods and algorithms Methods of estimating an economic lot size, suggested by different authors, have not found an application in short-run environment, which is typical for HEP, because of high labour coefficient, calculation complexity, lack of necessary basic data on particular components, аs well as static nature of suggested methods and difficulties of their application in short-run environment in connection with those factors.
While estimating product startup optimization of its size is carried out, taking into account not only assembly requirements for planning period, but also efficient workplace capacity, data up to minimum number of equipment adapting.

AL as the carbonization agent could benefit for the formation of charred layer and increase the char residue ratio, which led to the reduction in PHRR and enhanced the flame retardancy of the coating.

Elemental analysis data were obtained using Perkin Elmer model 2400 equipment.
Electrochemical data (Table 1) obtained for compounds DD-DC and DD-DC/MS show that at the concentration of 10 ppm, there is a considerable decrease in oxidation currents; however, for higher potentials (0.08 to 0.15), the whole oxidation reaction of the system is favored at 25, 50 and 100 ppm, which is observed by the current values greater than the blank (Fig. 4 just for DD-DC/MS).
In the cathodic reaction, it is noted that for all concentrations, a decrease in the reduction currents respect to the blank was observed, specifically at 10 ppm.
Furthermore, for DD-DC/MS, the cathodic slopes are also similar as the seen for DD-DC, indicating that the main process of the reduction reaction is not affected by the presence of the compound.

This explains the significant reduction in cost and duration of the object operation due to poor-quality of construction.
Therefore, the reduction of initial defects is so important in the construction of buildings.
The data was collected on the basis of estimates for the construction with the prices as of 2000, provided by OJSC "Design Institute for Planning and Development of Cities and Settlements" Magnitogorskgrazhdanproekt".
The data in the table are used to construct the graphs shown in Fig. 2.

Each section of the subsequent tooth cuts chips contrariwise if compared to the previous one; and the cutting edge goes towards zone of less hardening, which leads to reduction of specific load per linear unit of the cutting edge.
Such load reduction should lead to decrement of the machined surface hardening of titanium alloy as well as improvement of cutter wear-resistance.
The initial data for this analysis are (Fig. 3): • Wave tilt angle– • Tilt angle of wavelike edge at point A - • Orthogonal rake angle in the cutter normal section - • Clearance angle in the axial cutter section - It is necessary to determine: • Tilt angle of the cutting edge at point A in static coordinate system– (1) • Orthogonal clearance at point A in static coordinate system - Figure 3 shows the cutting part of the end milling cutter with wave-like edges.
These data can be used when wavy cutters design.
