Using modern differential geometric methods, we study the relative equilibria for Dirichlet's model of a self-gravitating fluid mass having at least two equal axes. We show that the only relative equilibria of this type correspond to Riemann ellipsoids for ...
The choice of an adequate actuation method is a central issue in the development of any mechatronic device and strongly determines the dynamic performances of the system. This choice is particularly difficult for robotic systems working within a magnetic r ...
We consider the Stokes problem in an axisymmetric three-dimensional domain with data which are axisymmetric and have angular component equal to zero. We observe that the solution is also axisymmetric and the velocity has also zero angular component, hence ...
A novel approach for measurement of small rotation angles using imaging method is proposed and demonstrated. A plane mirror placed on a precision rotating table is used for imaging the newly designed composite coded pattern. The imaged patterns are capture ...
We developed a new integrated magnetic sensor based on the Hall effect, suitable for the application in magnetic contactless 360° absolute angle sensors. The device consists of a narrow n-well ring with a chain of 64 contacts equally distributed around the ...
We present several examples of the applications of a novel microradiology approach based on unmonochromatized synchrotron x-rays. The approach - mostly implemented on the ICPCIR (International Consortium on Phase Contrast Imaging and Radiology) Beamline at ...
Sensory feedback from the moving limbs contributes to the regulation of animal and human locomotion. However, the question of the specific role of the various modalities is still open. Further, functional loss of leg afferent fibres due to peripheral neuro ...
We present a new application of digital holography for phase- contrast imaging and optical metrology. This holographic imaging technique uses a CCD camera for recording of a digital Fresnel off-axis hologram and a numerical method for hologram reconstructi ...
