Mechanical Design of a Ballbot Platform
(2013)In this thesis a new ball structure for ballbot Rezero is investigated with a load capacity of up to 100 kg. Furthermore low weight and a good form stability is desirable to enable easy actuation of the ball. Also the ball should provide enough friction on the ground to avoid slipping and a damping property so that small bumps like carpet edges are absorbed. With help of functional analysis a new ball version is found which consists of a ...Student Paper -

Equivalence of the catalytic entropy conjecture and the transitivity conjecture is plausible
(2019)In essence, the catalytic entropy conjecture states that for a given initial state and a target state with higher entropy there exists a unitary operator acting on the tensor product of the initial state and a state of an auxiliary system such that the marginal states after the action of the unitary are precisely the target state and the same auxiliary state respectively. Since the state of the auxiliary system remains unchanged, we refer ...Student Paper -
