An important part of the appraisal and market prices is depreciation, a reduction in price due to old age or a price increase due to rehabilitation, reconstruction or repair.
The finding is evident from the example: Table 1: Test-01 Expert 1 0 0 0 3 3 3 Expert 2 0 0 0 3 3 3 Expert 3 0 0 0 3 3 3 Expert 4 0 0 0 3 3 3 According to (3) we get the result: Table 2: Test-02 Expert 1 1 1 1 4 4 4 Expert 2 1 1 1 4 4 4 Expert 3 1 1 1 4 4 4 Expert 4 1 1 1 4 4 4 If 'move beginning ", it means that we use a different scale (Table 2) than that (Table 1), such as 1 ÷ 4, we obtain a logically consistent result by equation (4) For other data, such as additional objects, we obtain similar, but different evaluation resources, with the same (always the same) overall result Pck = 0.5.

Introduction The main requirement of the flywheel energy storage system in discharge link is stable output voltage; because of the continuous deceleration of the flywheel in the energy-releasing process and the continuous reduction of the voltage emitted by the permanent magnet synchronous generator, the change of the load also influences the voltage on the generator and then influences the voltage emitted by the generator; all those factors increase the difficulty of obtaining good and stable voltage output performance.
Through the data analysis, the voltage regulation rate and the output voltage ripple reach the design index and the power supply efficiency reaches 80%.

Because this device has a thicker bottom oxide layer, it should be capable of achieving a smaller gate-drain charge (Qgd) as well as further reductions in switching loss compared to a conventional MOSFET.
The data in Table 1 help to compare the simulated Qgd of the conventional trench SiC-MOSFET and the SiC-MOSFET with the thick bottom oxide trench gate structure.

Studies have found that suspended particulate matters from dredging and dumping not only make water clarity, dissolved oxygen reduction, but also affect phytoplankton photosynthesis and growth, zooplankton community structure that bring some toxic effects to plankton larvae [7]. [1] [4] [5] [6] studied the toxic effects of suspended solids on marine organisms respectively.

For reduction to its lowest terms, the machine doesn’t have damper windings and we won’t take the salient-pole and the quantity of the active resistance of the stator R into account.
are the main technical data of the machine: a synchronous reactance in the direct and quadrature axes, direct axis transient reactance, resistance of the stator winding, respectively [2].

The NC machining has the following characteristics, such as the remarkable flexibility and precision, the high productivity, the reduction of the labor intensity, the improvement of labor’s working condition, the conduciveness to modernization of production management and the improvement of economic efficiency.
(3) where n = the type number of the ith component’s failure mode = the fraction of the component i’s failures having failure mode j = the condition probability that failure mode j will result in the identified failure effect = the failure rate of component i The duration time of 87 failure data of the machining center is 56110.18 hours.
