BCC force calculation

1.

The methods of withdrawing bitcoin and Leyte coin are as follows:

1. You need to set your own collection account before withdrawing cash. You can set up your own bank account or bitcoin account. Check after setting to avoid unsuccessful withdrawal e to setting errors

2.

CCR model assumes that DMU is in the case of fixed returns to scale to measure the total efficiency

BCC model assumes that DMU is in the case of variable returns to scale, which is used to measure pure technology and scale efficiency

as a method to deal with multi-objective decision-making problems, the advantages of DEA are mainly reflected in the following three points:

1. There is no need to assume any weight, and the optimal weight of each input and output is obtained from the actual data of the decision-making unit, which can avoid subjective factors

The weight of each input and output of the decision-making unit is taken as the variable to evaluate from the perspective of the most beneficial to the decision-making unit, so as to avoid the weight of each index in the sense of priority

It is assumed that each input is related to one or more outputs, and there is a certain relationship between the inputs and outputs. The DEA method does not need to determine the display expression of this relationship

extended data

DEA is a linear programming model, expressed as the ratio of output to input. By comparing the efficiency of a specific unit with the performance of a group of similar units providing the same service, it tries to maximize the efficiency of the service unit. In this process, some units with 100% efficiency are called relative efficiency units, while others with efficiency scores lower than 100% are called inefficiency units

In this way, enterprise managers can use DEA to compare a group of service units, identify relative inefficiency units, measure the severity of inefficiency, and find ways to rece inefficiency by comparing inefficiency and efficiency units

4. a) The density of FCC is 0.74, the density of BCC is 0.68, so 0.74/0.68 = 1.088, the expansion is 1.088 times

b) {[(0.2892) ^ 3] / 2} / {[(0.3633) ^ 3] / 4} = 1.009, the expansion is 1.009 times

the reason for the difference is that the actual atomic arrangement is not as regular as the steel ball model, and there will be certain vacancies (especially at high temperature, the vacancy concentration is higher), which affects the volume.

5.

The linear density is determined by dividing the radius of the sphere in the unit cell by the length of the line where the atom is located

The area density is calculated by dividing the area of the sphere in the unit cell by the area of the surface on which the atom is located

6. BCC model is a model to evaluate technical efficiency. Relative efficiency means that the DEA efficiency in DEA model is relatively effective, that is to say, relative to other similar DMU units, it is not really technical efficiency and scale efficiency.

7. The function of check code is to judge whether the command character should be issued is complete. PLC receives the check code, which is used to judge the correctness of the received characters. If your environment is good, Panasonic mewtocol-com protocol allows "* *" to replace the check code
there is a good communication executable software between Panasonic PLC and VB on my webpage. You can download and try it:

if your problem is not solved, you can add my network hi account.

8. According to the formula, it can be calculated as follows:
can only enter one thousand, so a = 1
b = 8, C = 9
189 + 899 = 1088
