Recently, some of our users encountered the well-known error message sam error 12291. This problem can occur for a number of reasons. We will review them below.

If you are getting error code 31 on a specific network adapter, you may not have installed the correct driver for your network adapter, or the device driver may be corrupted. Ethernet adapter error code 31 can also appear if you have an invalid/corrupt service key in your registry.
In military science, Ballistic Error Probability Paper (CEP)[1] (also False Pick Circular[2] or Circle of Equal Probability[3 ]) a will be a measure of the weapon system’s accuracy. It is defined as the radius of a certain circle centered on the average, the limit of which must cover the landing problems of 50% of the turns; says, otherwise it is the average error radius.[4][5] That is, if so, this design of the ammunition keeps the KVO at 100 m, if one hundred shots in At the same point, fifty fall in a circle of a given radius of 100 m around their mid point of impact. (The distance between the target and just the midpoint of impact is entered as a deviation.)
There are related concepts such as DRMS (Distance Square Root), which is the square root of each distance root mean square error, and where r95 would be the radius of a circle representing the best 95% of the values thatthe fall .
The concept of CEP also plays a role in measuring the accuracy of a position obtained from a navigation system such as GPS or older systems such as LORAN and Loran-C.

The original concept of CEP was based on a circular bivariate normal distribution (CBN) with CEP as a parameter, where CBN as well as μ σ are related to the parameters of the normal distribution. Ammunition with this distribution tends to cluster around the mid-point of impact, mostly fairly close, getting closer and closer, and very little over long miles. That is, if the CEP is n meters, 50% of the shots hit within n meters of hitting, 43.7% means n is two to 2n, and 6.1% means 2n to 3n meters farther, and the percentage of needle hits hit farther than three. times its CEP of the average is only 0.2%.
CEP is not a good measure of perfection if this distribution behavior is not achieved. Precision-guided ammo usually has more “close hits” and also doesn’t spread normally. Ammunition may also have a standard deviatione in range is larger than the azimuth (deviation) errors associated with the standard deviation, resulting in an elliptical machine confidence interval. Samples of ammunition may not hit the target exactly, i.e. vector Be will not be (0,0). This is considered bias.
To account for accuracy in accordance with the concept of CEP under these conditions, CEP can be defined as the root mean square error (MSE). The MSE is the sum of the range error variance plus the given azimuth error variance plus my range error covariance multiplied by the azimuth error plus the square of the offset. So the MSE is the result of a combination of all these sources of error, the geometry and the corresponding radius of the circle where experts say 50% of the projectiles will hit.
How do I fix error code 31?
Restart your computer if you haven’t already.Did you install the device or scan in Device Manager just before the Code 31 error appeared?Revert the vehicle to an older version with yourtheir favorite updates.Use System Restore to undo recent changes related to Device Manager.
Several methods allow you to get an estimate of CEP based on shot data. These methods include all the pluggable approaches of Blishke and Halpin (1966), the Bayesian approach of Spall Marjak and hence (1992), and the maximum likelihood approach of Winkler and Bickert (2012). Spall and Marjak’s approach is applied when documents about theIt describes a mixture of different projectile components (for example, firing several types of ammunition in turn from different places aimed at a given target).

How do I reinstall my wireless adapter driver?
In Device Manager, select Network adapters. Then click “Action”. Click Scan for hardware changes. Windows then often detects the missing driver for your wireless network card and automatically reinstalls it.
While 50% is a very common definition associated with CEP, the size of a circle can be understood as a percentage. Percentiles can be determined given that the horizontal position error can be defined by a 2D vector whose edges are two orthogonal Gaussian random aspects (one for each axis) that are considered uncorrelated and each have a standard deviation of
