Conspiracism is a well‐known topos in the history of humankind. Cassius Dio wrote about it as did anti‐Judaic authors in the Middle Ages. Nevertheless, from the dawn of modernity until today, we have faced the rise of a new phenomenon. Pretty muc

Standard medium-voltage converters are operated at low switching frequencies using bulky passive components. One concept to change this involves the quasi-two-level operation (Q2O) of multilevel converters that use fast-switching semiconductors to mi

Die Medienfront ist heute ein wichtiger Kriegsschauplatz, den viele neben Land, Wasser und Luft für gleich wichtig halten. Terroristen fühlen sich in sozialen Medien wohler als man denken könnte. Im Netz können sie die asymmetrische Kräftevertei

We consider the $q$th root number function for the symmetric group. Our aim is to develop an asymptotic formula for the multiplicities of the $q$th root number function as $q$ tends to $\infty$. We use character theory, number theory and combinatoric

We use character theory and character estimates to show that the number of $T_2$-systems of $A_n$ is at least \begin{equation*} \frac{1}{8n\sqrt{3}}\exp\left(\frac{2\pi}{\sqrt{6}}n^{1/2}\right)(1+o(1)). \end{equation*} Applying this result, we obtain

We consider the probability $p(S_n)$ that a pair of random permutations generates either the alternating group $A_n$ or the symmetric group $S_n$. Dixon (1969) proved that $p(S_n)$ approaches $1$ as $n\to\infty$ and conjectured that $p(S_n)=1-1/n+o(1

The quasi-n-level operation of the flying capacitor converter (FCCs) is an optimized operation mode of a multilevel converter. The quasi-n-level operation of a multilevel converter was presented with an analysis of its advantages and disadvantages. F

Today’s standard medium voltage converters are operated with low switching frequencies and contain bulky passive components. One concept to change this is the Quasi-Two-Level operation of a multilevel converter with SiC semiconductors. A three-phas
