If you picked 30 more samples randomly from your population, how often would the results you got in your one sample significantly differ those other 30 samples? a 95% confidence level means that you would get the same results 95% of the time. 95% is the most commonly used confidence level but you may want a 90% or 99% confidence level depending.

The finite element analysis (fea) is the simulation of any given physical phenomenon using the numerical technique called finite element method (fem). Engineers use fea software to reduce the number of physical prototypes and experiments and optimize components in their design phase to develop better products, faster while saving on expenses.
The finite element method (fem), or finite element analysis (fea), is a computational technique used to obtain approximate solutions of boundary value problems in engineering. The field is the domain of interest and most often represents a physical structure.
December 2006 daniel gorenstein in february 1981 the classification of finite simple groups was completed. So wrote daniel gorenstein, the overseer of the programme behind this classification: undoubtedly one of the most extraordinary theorems that pure mathematics has ever seen. It should have been a landmark for modern mathematics, but it failed to attract much attention in the wider media.

Finite sample performance of linear least squares estimation michael krikheli 1;2and amir leshem abstract—linear least squares is a very well known technique for parameter estimation, which is used even when sub-optimal, because of its very low computational requirements and the fact that exact knowledge of the noise statistics is not required.
The performance of the proposed estimator was shown to be comparable to the performance of some of the well‐known estimators of the hurst exponent.
