## Dear Reader!

Welcome to my website!

Here I am frequently tweeting and blogging on statistics, signal processing, inverse problems, probability theory, telecommunications, history, and software development in English and German. Now it is even optimized for mobile viewing. Since LaTeX, Maxima, and Python are powerful open-source tools for doing research, I give some words of advice and present some code snippets. The software section shows some of my old software projects (C/C++).

Enjoy reading my website and don't hesitate to give me feedback!

## Résumé

*Currently, I am with Frequentis AG. I have been a consultant a**nd a service provider in information technology with focus on statistics, programming, communications, and streaming of live events,* which reflect my interests and hobbies.

From mid-2008 to mid-2009, I did my master thesis on RFID with NXP Semiconductors Austria. Afterwards, I was researcher in statistics / signal processing and teaching assistant with Institute of Telecommunications of Vienna University of Technology. From autumn of 2013 to spring of 2014, I did my research at Institute of Telecommunications of TU Darmstadt due to a fellowship of Federation of Austrian Industries. Afterward I was self-employed and became a certified project-management associate. See my LinkedIn profile or contact me for my detailed curriculum vitae.

My research's foci are statistics, signal processing, and probability theory in the area of (mobile) communications. I did my work in cooperation with Prof. Christoph Mecklenbräuker (PhD advisor), Prof. Peter Gerstoft, Prof. Gerald Matz, Prof. Marius Pesavento, and Prof. Norbert Goertz.

## Favorite Quotation

If people do not believe that mathematics is simple, it is only because they do not realize how complicated life is.

There are several problems, if you want to make a picture slideshow, which shall be transmitted through Whatsapp:

- You need a Whatsapp compatible video format.
- Pictures may have different formats / resolutions.
- Smart-phone displays have wide screens.
- Whatsapp's upper bound of a video's file size is 16MB.
- How to make subtitles?

In what follows, you will find my quick and dirty solution. Note that you need Linux with GNU parallel, ImageMagick, and ffmpeg installed.

*Note that this is only a first draft, a first sketch, but you should get an idea ;-). *

A tensor is a physical quantity. In one dimension, temperature is a tensor. One dimensional tensors are called scalars (tensor of zero oder). But the temperature is independent of its representation. You can specify it in Kelvin or in degree Celsius.
