# Double tagged equations?
In the following example
the inequality (2.26) is obtained in the environment equation, but the equations (2.27) and (2.28) by dirty tricks, destroying the structure of the document. This is because additional tags (i) and (ii) are needed on the left-hand side of lines. (This is, in fact, s... | |
# Technological challenges to sending a high altitude balloon to space and orbit from 50 km?
If you want to be above all winds, you have to be above all atmosphere. But you can't get above all atmosphere with a ballon. There is no ballon lighter than a vacuum.
Conventional helium balloons get up to roughly 50 km, whi... | |
# Synchronous motor mystery
Not too long ago I acquired an old ('70/'80) German flip clock. I found out that this clock is driven by a one-phase synchronous engine.
I can't get the motor to run. I (carefully!) connected the motor to the mains (220V 50Hz). The results was a chaotic buzzing and the motor oscillating. T... | |

# Extensions of solutions of a functional equation in two variables
Abstract. An extension theorem for the functional equation of several variables $f(M(x,y))=N(f(x),f(y)),$ where the given functions $$M$$ and $$N... | |
In other word, as we move away from the training point, we have less information about what the function value will be. Gaussian process regression (GPR) is a Bayesian non-parametric technology that has gained extensive application in data-based modelling of various systems, including those of interest to chemometrics.... | |

# Condition for Element of Quotient Group of Additive Group of Reals by Integers to be of Finite Order
## Theorem
Let $\struct {\R, +}$ be the additive group of real numbers.
Let $\struct {\Z, +}$ be the additive group of integers.
Let $\R / \Z$ denote the quotient group of $\struct {\R, +}$ by $\struct {\Z, +}$.

# How do you convert 3.92 x 10^2 into standard form?
##### 1 Answer
Jul 26, 2015
You get $392$ by moving the point to the right.
#### Explanation:
look at the power of $10$: you move the point to the right of many places as the (positive) value of the exponent of 10, which, in this case is $2$.
You get:
$3.92 \to$ ... | |

# Bayesian analysis of a probability of success
Let $S \sim \text{Bin}(N, \pi)$ denote a number of successes. Using the non-informative $\text{Beta}(0.5, 0.5)$ prior, the posterior distribution of the probability of success is $$\text{Beta}(0.5 + S, \, 0.5 + N - S)$$
Say that the interest is in the posterior probabil... | |
