Nichtinvasive Erfassung elektrophysiologischer Parameter zur Beurteilung von Muskelermüdung unter isometrischen und dynamischen Kontraktionen
… between muscle and electrode array lead to effects in the EMG signal, that do not correlate to physiological alterations. These geometrical effects and their consequences on electrophysiological parameters were investigated. The most important parameter in respect of dynamic HSR-EMG …

Magnetotransport Effects in Three Dimensional Nanocircuits
… density memory, but also provide access to 3D geometrical effects such as chirality and curvature, which may lead to new physics. However, significant advances in both the fabrication of 3D spintronic devices and our fundamental understanding of the influence of 3D geometries on …

Stabilizing energy reconstructions of the surface detector at the Pierre Auger Observatory
… Law functions. As instabilities are products of geometrical effects leading to poor constrainment of the energy estimator 1000 m from the shower axis, this thesis explores reconstructions using the signal at 1500 m, but, finding the instabilities exacerbated, separate reconstructions for the …

Computational study of hot electron generation and energy transport in intense laser produced hot dense matter
… the coupling of laser energy to a dense plasma. Geometrical effects on hot elec- tron transport and target heating processes are examined in the reduced mass target experiments. Further, pertinent to fast ignition, laser accelerated fast electron diver- gence and transport in the experiments …

Geometrical control of domain walls and the study of domain wall properties of materials with perpendicular magnetic anisotropy
… or logic devices. I will then discuss how to geometrically control the behaviors of DWs in a ferromagnetic nanowire. I will first discuss how natural geometry distortions such as edge tapering from sputtering on an undercut resist profile and wire width variation from the patterning process …

Mitigation of RF sheaths through design and implementation of magnetic field-aligned ICRF antenna
… of E-parallel is more modest, suggesting 3-D geometrical effects are important. Multiple antenna phases were analyzed for the field-aligned antenna using finite element method with a 3-D toroidal cold plasma model. In each case, the field-aligned antenna had reduced integrated E-parallel …

Aerodynamic Performance of High Turning Airfoils and the Effect of Endwall Contouring on Turbine Performance
… aerodynamic losses through design changes and geometrical effects. Performance of airfoils with varying loading levels and turning angles at transonic flow conditions are investigated in this study. The pressure difference between the pressure side and suction side of an airfoil gives an …

Buckling Patterns and Mechanics of Thin Interfacial Polymer Films
… non-linearities are shown to arise from purely geometrical effects that modify the stress field and film profile. We harness this same experimental setup to characterize the threshold for the formation of folds; regions where material spontaneously localizes and contacts itself. We show that a …

The effect of topography on the Martian atmospheric circulation and determining Pluto's atmospheric thermal structure from stellar occultations
… were considered that either contained the effects of convection or did not. When convective effects were allowed, the presence of the slope component shifted the dividing streamline upslope, qualitatively similar to a change of season in the original Lindzen and Hou [1988 (flat) model. The …

Studies on the physical structure, properties and operation of ionic liquid electrosprays in the pure-ion mode
… validated, and that aims to explore electrode geometrical effects, the current and the stability of ionic liquid pure-ion electrospray menisci. The model takes into account the specific geometry of the sources and reveals emitted current ranges where the pure-ion regime can be sustained. …

Cantilever Dynamic Analysis in Tapping Mode Atomic Force Microscopy
… Moreover, it does not take into account geometrical effects of the tip and the cantilever. However, correct interpretation of phase images still poses a significant challenge to the AFM community. In this study, the cantilever’s dynamic behaviour in tapping mode AFM is studied through a …

Tooling performance in micro milling: Modelling, simulation and experimental study
… support of FEM simulation developed, the tooling geometrical effects, including those from helix angle, rake angle and cutting edge radius with influences on cutting forces, tool stresses, tool temperatures, milling chip formation and temperatures have been comprehensively studied and compared for …
