Object contour sensing using artificial rotatable vibrissae
Recent research topics in bionics focus on the analysis and synthesis of mammal’s perception of their environment by means of their vibrissae. Using these complex tactile sense organs, rats and mice, for example, are capable of detecting the distance to an object, its contour and its surface texture.…
Characterizing the outer ear transfer function in dependence of interindividual differences of outer ear geometry
The outer ear transfer function can be used to describe the influence of the outer ear canal and its geometric variance in cross-section as well as its path on the sound field in the ear canal and the sound pressure level resulting at the ear drum.
The variance of outer ear geometry is described by…
Requirements and potentials of human kinetic energy harvesting technologies with focus on electromagnetic conversion methods
In the recent years, energy harvesting has become increasingly popular for powering low-energy devices. Therefore, human power has become a promising energy source in providing electrical energy. Thus, the general principles, structures, requirements and potentials of human kinetic energy harvesting…
Multi-segmented artificial locomotion systems with adaptively controlled gait transitions
This paper is devoted to the analysis and simulation of multi-segmented artificial locomotion systems. The biological paradigm is the earthworm. Here, we restrict our investigation to a crawling system which is moving along a straight line, more precisely, the system is firstly moving unidirectionally.…
Control of compliant robotic systems with muscle-like actuators and saturated feedback
This paper is devoted to the problem in controlling a compliant robotic system by means of actuators with musclelike properties, which underlie prescribed bounds due to the natural muscle behavior. A typical example to demonstrate the effectiveness of developed control schemes is the choice of a (inverted)…

Allegorische Diagrammatik und diagrammatische Allegorisierung. Erkenntnisprozesse in einem allegorischen Ikonotext der ‚Regia…
Subject of this essay is the question of how the invisibility of God can be visualized. The ‘Regia Carmina’ of Convenevole da Prato (London, British Library, Royal 6 E IX) serves as an example. They are designed through allegorical iconotexts. Convenevole’s reflection consists basically of a mental image…

"Kennst du das Land, wo blüht Oranienbaum?" - A Case Study on Strategic and Territorial Planning in St. Petersburg (Russia)
The research examines the system of strategic and territorial planning of St. Petersburg focusing on Lomonosov (Oranienbaum) as its case study. The study provides the analysis of the planning documentation developed for the city in the post-Soviet period. In particular, it elaborates on the currently…
Prospects for Biochar in a Bio-Waste Cascade
In the early 2000s the pre-Columbian, anthropologically produced black soil in the Amazon basin, „Terra Preta de Índio“, received greater scientific attention. Compared to the surrounding poor soils, this very fertile anthrosol contains significantly higher levels of microorganisms and nutrients. The…
