Trigonometric words ranking model for spam message classification
IET Networks, EarlyView., 2022 Abstract The significant increase in the volume of fake (spam) messages has led to an urgent need to develop and implement a robust anti‐spam method. Several of the current anti‐spam systems depend mainly on the word order of the message in determining the spam message, which results in the system's inability to predict the correct type of message when

Families of Integrals of Polylogarithmic Functions
Mathematics, 2019 We give an overview of the representation and many connections between integrals of products of polylogarithmic functions and Euler sums. We shall consider polylogarithmic functions with linear, quadratic, and trigonometric arguments, thereby producing ...

The calculus of the trigonometric functions
Historia Mathematica, 1987 AbstractThe trigonometric functions entered “analysis” when Isaac Newton derived the power series for the sine in his De Analysi of 1669. On the other hand, no textbook until 1748 dealt with the calculus of these functions. That is, in none of the dozen or so calculus texts written in England and the continent during the first half of the 18th century ...

Generalized trigonometric functions and their applications
Вісник Астрономічної школи, 2015 The basics of generalized trigonometric functions theory are developed. We give an example of this theory application illustrating the effect of frequencies deployment which is inverse to the well-known effect of overlaying frequencies.

Dihedral Gauss hypergeometric functions
, 2011 Gauss hypergeometric functions with a dihedral monodromy group can be expressed as elementary functions, since their hypergeometric equations can be transformed to Fuchsian equations with cyclic monodromy groups by a quadratic change of the argument ...

3D‐Printed Architected Material for the Generation of Foam‐Based Protective Equipment
Advanced Engineering Materials, EarlyView.This study investigates 3D‐printed architected structures as alternatives to traditional foams in protective gear. It focuses on customizing impact strength and damping through design and manufacturing integration. Testing shows these structures outperform conventional foams, offering enhanced customizability, lower weight, and tunable performance ...

Measure theoretic trigonometric functions [PDF]
Journal of Fractal Geometry, Mathematics of Fractals and Related Topics, 2015 We study the eigenvalues and eigenfunctions of the Laplacian \Delta_{\mu}=\frac{d}{d\mu}\frac{d}{dx} for a Borel probability measure \mu on the interval [0,1] by a technique that ...

Gaussian Qualitative Trigonometric Functions in a Fuzzy Circle
Advances in Fuzzy Systems, 2018 We build a bridge between qualitative representation and quantitative representation using fuzzy qualitative trigonometry. A unit circle obtained from fuzzy qualitative representation replaces the quantitative unit circle.
