T1  - 3D object recognition with a specialized mixtures of experts architecture
T2  - IJCNN'99. International Joint Conference on Neural Networks. Proceedings
N2  - Aim of the AXON2 project (Adaptive Expert System for Object Recogniton using Neuml Networks) is the development of an object recognition system (ORS) capable of recognizing isolated 3d objects from arbitrary views. Commonly, classification is based on a single feature extracted from the original image. Here we present an architecture adapted from the Mixtures of Eaqerts algorithm which uses multiple neuml networks to integmte different features. During tmining each neural network specializes in a subset of objects or object views appropriate to the properties of the corresponding feature space. In recognition mode the system dynamically chooses the most relevant features and combines them with maximum eficiency. The remaining less relevant features arz not computed and do therefore not decelerate the-recognition process. Thus, the algorithm is well suited for ml-time applications.

T1  - Werkstatt voller Historie
N2  - Das Buch „Werkstatt voller Historie“ gibt einen Einblick in das Handwerk der Restaurierung und Konservierung. Wir leben in einer Gesellschaft, die von Konsum und schneller Verfügbarkeit geprägt ist. Produkte werden in Massen produziert, genutzt und oft schon nach kurzer Zeit wieder weggeworfen. Durch diese Mentalität der Wegwerfgesellschaft werden die Ressourcen unserer Erde erschöpft, und Umweltprobleme werden immer größer. Deshalb ist es wichtig, sich intensiv mit der Bewahrung von Kulturgut auseinanderzusetzen. Durch die Verwendung von Illustrationen und visuellen Darstellungen erleichtert das Buch die Kommunikation. Dadurch kann der Restaurierungsprozess einfacher verstanden werden. Mit dem Projekt soll das Interesse geweckt und über die Grundlagen und Herausforderungen der Restaurierung aufgeklärt werden.

T1  - The Anticipation of Gravity in Human Ballistic Movement
JF  - Frontiers in Physiology
N2  - Stretch-shortening type actions are characterized by lengthening of the pre-activated muscle-tendon unit (MTU) in the eccentric phase immediately followed by muscle shortening. Under 1 g, pre-activity before and muscle activity after ground contact, scale muscle stiffness, which is crucial for the recoil properties of the MTU in the subsequent push-off. This study aimed to examine the neuro-mechanical coupling of the stretch-shortening cycle in response to gravity levels ranging from 0.1 to 2 g. During parabolic flights, 17 subjects performed drop jumps while electromyography (EMG) of the lower limb muscles was combined with ultrasound images of the gastrocnemius medialis, 2D kinematics and kinetics to depict changes in energy management and performance. Neuro-mechanical coupling in 1 g was characterized by high magnitudes of pre-activity and eccentric muscle activity allowing an isometric muscle behavior during ground contact. EMG during pre-activity and the concentric phase systematically increased from 0.1 to 1 g. Below 1 g the EMG in the eccentric phase was diminished, leading to muscle lengthening and reduced MTU stretches. Kinetic energy at take-off and performance were decreased compared to 1 g. Above 1 g, reduced EMG in the eccentric phase was accompanied by large MTU and muscle stretch, increased joint flexion amplitudes, energy loss and reduced performance. The energy outcome function established by linear mixed model reveals that the central nervous system regulates the extensor muscles phase- and load-specifically. In conclusion, neuro-mechanical coupling appears to be optimized in 1 g. Below 1 g, the energy outcome is compromised by reduced muscle stiffness. Above 1 g, loading progressively induces muscle lengthening, thus facilitating energy dissipation.

T1  - Changes in gravity affect neuromuscular control, biomechanics, and muscle-tendon mechanics in energy storage and dissipation tasks
JF  - Journal of Applied Physiology
N2  - This study evaluates neuromechanical control and muscle-tendon interaction during energy storage and dissipation tasks in hypergravity. During parabolic flights, while 17 subjects performed drop jumps (DJs) and drop landings (DLs), electromyography (EMG) of the lower limb muscles was combined with in vivo fascicle dynamics of the gastrocnemius medialis, two-dimensional (2D) kinematics, and kinetics to measure and analyze changes in energy management. Comparisons were made between movement modalities executed in hypergravity (1.8 G) and gravity on ground (1 G). In 1.8 G, ankle dorsiflexion, knee joint flexion, and vertical center of mass (COM) displacement are lower in DJs than in DLs; within each movement modality, joint flexion amplitudes and COM displacement demonstrate higher values in 1.8 G than in 1 G. Concomitantly, negative peak ankle joint power, vertical ground reaction forces, and leg stiffness are similar between both movement modalities (1.8 G). In DJs, EMG activity in 1.8 G is lower during the COM deceleration phase than in 1 G, thus impairing quasi-isometric fascicle behavior. In DLs, EMG activity before and during the COM deceleration phase is higher, and fascicles are stretched less in 1.8 G than in 1 G. Compared with the situation in 1 G, highly task-specific neuromuscular activity is diminished in 1.8 G, resulting in fascicle lengthening in both movement modalities. Specifically, in DJs, a high magnitude of neuromuscular activity is impaired, resulting in altered energy storage. In contrast, in DLs, linear stiffening of the system due to higher neuromuscular activity combined with lower fascicle stretch enhances the buffering function of the tendon, and thus the capacity to safely dissipate energy.

T1  - Search for life in ice-covered oceans and lakes beyond Earth
T2  - 2018 IEEE/OES Autonomous Underwater Vehicle Workshop, Proceedings November 2018, Article number 8729761
N2  - The quest for life on other planets is closely connected with the search for water in liquid state. Recent discoveries of deep oceans on icy moons like Europa and Enceladus have spurred an intensive discussion about how these waters can be accessed. The challenge of this endeavor lies in the unforeseeable requirements on instrumental characteristics both with respect to the scientific and technical methods. The TRIPLE/nanoAUV initiative is aiming at developing a mission concept for exploring exo-oceans and demonstrating the achievements in an earth-analogue context, exploring the ocean under the ice shield of Antarctica and lakes like Dome-C on the Antarctic continent.

T1  - Generative Gestaltung: wie eine Herangehensweise die Zukunft des Designs revolutionieren könnte.
N2  - Diese Bachelorarbeit setzt sich mit der „Generativen Gestaltung“ und ihren Möglichkeiten für Gestaltende auseinander. Die automatisierte Bearbeitung eines gestalterischen Projektes soll vorrangig Vorteile beim Arbeiten mit großen Datenmengen bieten.

Ziel war es, eine Plakatreihe zu entwerfen, die auf der Grundlage eines Codes - also eines strikten Regelwerks - basiert. Mithilfe dieses Verfahrens kann auf Knopfdruck eine beliebige Menge an Plakaten generiert werden. Durch die Festlegung bestimmter Parameter innerhalb des Codes wird gewährleistet, dass jedes ausgespielte Plakat anders ist als sein Vorgänger.
Diese Arbeit dient als eine erste anskizzierte Grundlage dafür, wie grafischer Output automatisiert und vor allem aktualisiert generiert werden kann. Dieses Prinzip kann auf eine Vielzahl von Inhalten und Umsetzungen angewendet werden.
