Entropy-Based Clustering Algorithm for Fingerprint Singular Point Detection [PDF]
Entropy, 2019 Fingerprints have long been used in automated fingerprint identification or verification systems. Singular points (SPs), namely the core and delta point, are the basic features widely used for fingerprint registration, orientation field estimation, and ...

Моделирование и анализ информационных систем, 2018 In this paper, we consider the key problem of geometric modeling, connected with the construction of the intersection curves of surfaces. Methods for constructing the intersection curves in complex cases are found: by touching and passing through ...

Parametric Expansions of an Algebraic Variety near Its Singularities
Axioms, 2023 Presently, there is a method based on Power Geometry that allows one to find asymptotic forms and asymptotic expansions of solutions to different kinds of non-linear equations near their singularities.

Acta et Commentationes: Ştiinţe Exacte şi ale Naturii, 2023 The present study delves into the investigation of phase portraits of polynomial differential systems, which are systems of differential equations of the form $\frac{dx}{dt} = P(x,y), \frac{dy}{dt} = Q(x,y)$, where $x$ and $y$ are the dependent ...

Newton-Anderson at Singular Points
International Journal of Numerical Analysis and Modeling, 2023 In this paper we develop convergence and acceleration theory for Anderson acceleration applied to Newton's method for nonlinear systems in which the Jacobian is singular at a solution. For these problems, the standard Newton algorithm converges linearly in a region about the solution; and, it has been previously observed that Anderson acceleration can ...

Point Singularities in Incompatible Elasticity [PDF]
Journal of Elasticity, 2021 The equations of stress equilibrium and strain compatibility/incompatibility are discussed for fields with point singularities in a planar domain. The sufficiency (or insufficiency) of the smooth maps, obtained by restricting the singular fields to the domain away from the singularities, in completely characterizing the equations of equilibrium and ...

Studying Stability of a Non-linear Autoregressive Model [PDF]
مجلة التربية والعلم, 2018 In this paper we study the stability of one non-linear autoregressive model with hyperbolic triangle function polynomial with hyperbolic tangent function (singular point and it's stability conditions and the stability of the limit cycle) by using the ...

Unequal Interval Dynamic Traffic Flow Prediction with Singular Point Detection
Applied Sciences, 2023 Analysis of traffic flow signals plays an important role in traffic prediction and management. As an intrinsic property, the singular point of a traffic flow signal labels a new nonsteady status.

Analysis of the Oscillating Motion of a Solid Body on Vibrating Bearers
Machines, 2019 This article considers the oscillation of a solid body on kinematic foundations, the main elements of which are rolling bearers bounded by high-order surfaces of rotation at horizontal displacement of the foundation.
