INVESTIGATING THE METABOLIC PROFILE OF RUN-UP RACES AND THE MECHANICS OF WOBBLING VISCERAL MASS IN VERTICAL JUMPS.
This Thesis is organized in two parts based on two different investigations about human motion: the metabolic and mechanical analysis of ‘skyscraper running’, and the estimation of the visceral mass displacement in vertical jumps. Skyscraper running is a novel sport activity, in which the athletes …

Collector size effect on the measurement of applied water depth from irrigation systems
… was studied for spinning plate, fixed plate, and wobbling plate sprinkler systems. Five different collector sizes (C2 (5.5 cm), C4 (10.0 cm), C6 (14.8 cm), C8 (20.0 cm), and C10 (27.4 cm)) were studied using four 5x5 Latin squares. Each collector’s water depth was measured and statistically …

Analytical perspectives on localized solutions of the phi-4 theory
… end, we consider the evolution of the kink's wobbling and rocking modes and their coupling. To improve the asymptotic expansion of the wobbling and rocking amplitudes, we introduce a slowly varying width of the kink. The analysis of the wobbling and rocking modes produces three-dimensional …

Drone Cellular Networks: Fundamentals, Modeling, and Analysis
… For that, we first study the impact of UAV wobbling on the coherence time of the wireless channel between UAVs and a ground UE, using a Rician multi-path channel model. We consider two different scenarios for the number of UAVs: (i) single UAV scenario (SUS), and (ii) multiple UAV scenario …

Analysis and Modeling of Magnetized Microswimmers: Effects of Geometry and Magnetic Properties
… dipoles. Through these models, we explain the wobbling phenomena, reported by experimentalists. Our model predicts the existence of multiple stable solutions under certain conditions. This leads to the realization that control strategies can be improved by adjusting the angle between the …

Design Space and Motion Development for a Pole Climbing Serpentine Robot Featuring Actuated Universal Joints
… structures. Movement is produced by inducing a wobbling motion between adjacent modules through oscillatory motions in the actuated axis of the universal joint. Through the frictional interactions between the modules of the serpentine and the surface of the pole, the wobbling motion lets the …

A trajectory equation for walking droplets : hydrodynamic pilot-wave theory
… analysis also predicts the existence of wobbling orbital states reported in recent experiments, and the absence of stable orbits in the limit of large vibrational forcing. In this limit, the complex walker dynamics give rise to a coherent statistical behavior with wave-like features. We …

Efficient Object-Oriented Modelling, Simulation and Parameter Estimation for Biomechanical Problems
… biomechanical elements like passive muscles and wobbling masses. As Natural Coordinates lead to a set of redundant coordinates, we have to relax to treat inconsistent variables during the optimization process. To efficiently generate the sensitivity information needed for the optimization …

Investigating CO2 Adsorption Behavior in Metal-Organic Frameworks by Solid-state NMR
… Additionally, CO2 undergoes C2 hopping and C3 wobbling motion for both MOFs. Once single component adsorption was examined, co-adsorption of CO2 and water was also investigated for [Zn2(TRZ)2(NH2-BDC)].

An examination of bank use of credit derivatives to mitigate risk: an empirical analysis of its potency and impact on bank portfolio management and performance
… pre-crisis period as everything was still in a wobbling mode. Furthermore, moral hazard was also identified as one of the reasons for the lapses which led to the crisis and thus bank portfolio performance. This study concludes that credit derivatives do affect bank portfolio persistence, risk …

Characterizing Ultrafast Equilibrium Dynamics Using Third-Order Nonlinear Mid-Infrared Spectroscopies
… of spatial restriction was quantified using the wobbling-in-a-cone model. The addition of phenyl groups in the ligands acted to create more accessible local environmental configurations for the azide group. The binding configuration and intramolecular motion of the vibrational probe can affect …

Identifizierung und Charakterisierung des krankheitsauslösenden Gens in einem Mausmodell für humane Motoneuronerkrankungen
… mice show a tremor in the forelimbs and a wobbling gait. In spinal cord and brain stem degeneration of motoneurons can be observed, which leads to a muscular atrophy in shoulder and neck areas. Due to the progressive character of this disease, Wobbler animals can grasp no longer at the age …

A systems biology approach unravels the biological function of two tRNA wobble base modifications in fine-tuning translation and the response to environmental stress
… implicated these modifications in modulating wobbling capacity. Moreover, mutations in the <i>ELP</i>- and <i>URM1</i>-pathway genes have been associated with physiological defects in several organisms, including complex neurological disorders in humans. In this thesis we used a systems …

Two Dimensional Linear Finite Element Analysis Of Post-tensioned Beams
… stress losses on the tendons due to friction, wobbling and anchorage loss, under gradual loading and consecutive post-tensioning of two tendons, the results are compared with the ones reported using the program BEFE [5] developed at the University of Technology Graz, Austria. The results …

Exploring the spectroscopy of vibrational levels in the 160 mass region
… features, is the identification of the γ wobbling candidate, which implies in some way that 156Dy is γ deformed. Extensions have been made on the γ bands and they are now observed to spins 31+ and 32+, which marks the highest spin to be ever observed for both the odd and even spin members …

Vibration as a method for muscular stimulation
… stimulation frequency. Soft tissues act as wobbling masses vibrating in a damped manner in response to mechanical excitation; Muscle Tuning hypothesis suggest that neuromuscular system works to damp the soft tissue oscillation that occurs in response to vibrations; muscles alters their …
