2020 International Symposium on Electromagnetic Compatibility - EMC EUROPE, 2020
Symmetry is important for differential-transmission lines, but the dense parallel traces easily break the symmetry due to coupling with the adjacent conductor, leading to mode conversion. We propose an asymmetric geometry of differential-transmission lines placed on the side of a nonadjacent conductor to suppress mode conversion and maintain signal ...

Surfaces of constant principal-curvatures ratio in isotropic geometry
Beiträge zur Algebra und Geometrie / Contributions to Algebra and Geometry, 2023We study surfaces with a constant ratio of principal curvatures in Euclidean and simply isotropic geometries and characterize rotational, channel, ruled, helical, and translational surfaces of this kind under some technical restrictions (the latter two ...

Journal of the American Society for Mass Spectrometry, 2023
Differential ion mobility spectrometry (FAIMS) had emerged in the 2000s as a novel tool for postionization separations in conjunction with mass spectrometry (MS). High-definition FAIMS introduced a decade ago has enabled resolution of peptide, lipid, and

Highly accurate computation of volume fractions using differential geometry
Journal of Computational Physics, 2019This paper introduces a novel method for the efficient and accurate computation of the volume of a domain whose boundary is given by an orientable hypersurface which is implicitly given as the iso-contour of a sufficiently smooth level-set function ...

The Geometry of Differential Privacy: The Small Database and Approximate Cases
SIAM journal on computing (Print), 2016In this work, we study trade-offs between accuracy and privacy in the context of linear queries over histograms. This is a rich class of queries that includes contingency tables and range queries and has been a focus of a long line of work.

Mechanism and Machine Theory, 1997
Based on the results of Parts I and II, the kinematic conditions for the moving body to be connected with a binary link by a kinematic pair are discussed and described by the geometrical properties of the line trajectory and the constraint ruled surface.

DIFFERENTIAL EQUATIONS OF THE DEVICE SHELL WITH ARBITRARY GEOMETRY OF THE MERIDIAN LINE
Naukovì Dopovìdì Nacìonalʹnogo Unìversitetu Bìoresursiv ì Prirodokoristuvannâ UkraïniThe theory describes the shell part of the apparatus as a surface with an arbitrary geometric outline and general acting factors. A mathematical model is constructed, and boundary conditions are formulated to determine the coordinate deformation functions of the shell part under any external disturbances.
