Exercise 2
Um wie viel verringert sich nach dem Abstandsquadratgesetz, mit der Formel $I=\frac{P}{A}=\frac{P}{4\pi r^2}$, die Strahlungsintensität wenn sich der Abstand der Strahlungsquelle verdoppelt? Zeige es anhand der Formel.

Unit Step Function:
$u(t-a)=\begin{cases}
1,&t>a\
0,&t<a
\end{cases}$
The constant $a$ shifts the unit function to the right. Somtimes $u(t)$ is also refered to as the function $\epsilon(t)$.
Special property: $\int_{-\infty}^{\infty}u(t-a)x(t)dt=\int_{a}^{\infty}x(t)dt$

Introduction
In the following, the process of developing and building a DUT environment will be illustrated. The intended usecase and underlying problem is based upon the comparison of commercial-grade hardware like Raspberry Pis and industrial computational plattforms. To make well-founded comparisons and assumptions about their key differences and their performce under different aspects, the following data shall be collected:
Power consumption
Overall system stability / system uptime
Synthetic benchmark performance
On top of that, the tests can be performed under the influence of being tested in an environmental chamber as well. Every DUT will be connected via additional hardware to a central Raspberry Pi, which controls the currently running tests and also logs the individual metrics that are being recorded. The data can also analyzed and processed simultaniously by the Raspberry Pi and accessed from a remote client.
