A human‐robot collaboration method for uncertain surface scanning

open access: yesCAAI Transactions on Intelligence Technology, EarlyView., 2023
Abstract Robots are increasingly expected to replace humans in many repetitive and high‐precision tasks, of which surface scanning is a typical example. However, it is usually difficult for a robot to independently deal with a surface scanning task with uncertainties in, for example the irregular surface shapes and surface properties.

Finding the sum of any series from a given general term [PDF]

open access: yesarXiv, 2008
Translation from the Latin original, "Inventio summae cuiusque seriei ex dato termino generali" (1735). E47 in the Enestrom index. In this paper Euler derives the Euler-Maclaurin summation formula, by expressing y(x-1) with the Taylor expansion of y about x.

Effect of display luminance and ambient illuminance on the perceived quality of indoor environment images

open access: yesJournal of the Society for Information Display, EarlyView.
In a psychophysical experiment, participants evaluated the quality (preference, visual complexity, visual clarity, colorfulness, and visual interest) of images of indoor environments under different display luminance (50 cd/m2 and 250 cd/m2) and ambient illuminance (50 lx, 150 lx, 450 lx, and 900 lx) conditions.

Euler Characteristics of Finite Homotopy Colimits [PDF]

open access: yesarXiv, 2018
In this short note, we provide a calculation of the Euler characteristic of a finite homotopy colimit of finite cell complexes, which depends only on the Euler characteristics of each space and resembles Mobius inversion. Versions of the result are known when the colimit is indexed by a finite category, but the behavior is more uniform when we index by

Regularity and separation for Grušin‐type p‐Laplace operators

open access: yesMathematische Nachrichten, EarlyView.
Abstract We analyze p‐Laplace type operators with degenerate elliptic coefficients. This investigation includes Grušin‐type p‐Laplace operators. We describe a separation phenomenon in elliptic and parabolic p‐Laplace type equations, which provide an illuminating illustration of simple jump discontinuities of the corresponding weak solutions ...

Congruence properties of Lehmer-Euler numbers [PDF]

open access: yesarXiv
Certain generalization of Euler numbers was defined in 1935 by Lehmer using cubic roots of unity, as a natural generalization of Bernoulli and Euler numbers. In this paper, Lehmer's generalized Euler numbers are studied to give certain congruence properties together with recurrence and explicit formulas of the numbers.

Computational Modeling of the Continuous Separation of a Molten Polymer Mixture in a Centrifugal Field

open access: yesMacromolecular Theory and Simulations, EarlyView.
A centrifugal technique for separating molten polymer blends is investigated computationally. In a rotating cylinder, the components of mixtures of LDPE (Low‐Density Poly(Ethylene)) and PET (Poly(Ethylene) Terephthalate) are separated due to centrifugal forces due to the different component densities.

Boundedness and stability of nonlinear hybrid stochastic differential delay equation disturbed by Lévy noise

open access: yesIET Control Theory &Applications, Volume 17, Issue 1, Page 109-122, January 2023., 2023
Abstract This study focuses on the boundedness and stability of the nonlinear hybrid stochastic differential delay equation (NHSDDE) disturbed by Lévy noise (LN). Different from the previous systems with Markovian switching, not only different parameters under different modes, but also different structures under different modes are considered, where a ...
