3D printing of an object moving by hygroscopic stimulation

In this project, a complete product development process was carried out; the result is a functioning, energy-autonomous, biodegradable small robot. For this purpose, the latest results from cutting-edge research were taken into account, material behaviour was characterised, physical processes were modelled analytically and numerically, prototypes were built, and functionality was tested experimentally. The developed product, called “Hygrobot”, draws its energy …

Theoretical and Experimental Analysis of a Generalised Brachistochrone Problem for Mechanical Systems Including Coulomb Friction and Rotational Motion

The work provides a definition of a generalised form of the Brachistochrone problem for arbitrary mechanical systems. The problem then is solved for mechanical systems including Coulomb friction and/or rotational motion. By studying the solution curves, an interesting relation between the solution curve for systems with Coulomb friction and the cycloid has been shown. To estimate influences of simplifications made …

The influence of Roman rites on key events of ancient Rome

The influence of Roman rites on key events in Ancient Rome. At the battle of Marathon, the Spartans, celebrating Apollo, did not immediately come to Athenians’ rescue: religion took precedence over military strategy. Was this also the case with the Romans? What role did rituals play in Roman life? In this research, I looked at the influence of different rites …
