Logistic rice model for dry matter and nutrient uptake
Scientia Agricola, 2003 The temporal variation of cumulative dry matter can be represented by a sigmoidal curve and the temporal variation of nutrient uptake follows this characteristic shape. Therefore, modeling the temporal variation of cumulative dry matter allows estimating

Derivatives of meromorphic functions and sine function
Proceedings of the Japan Academy, Series A, Mathematical Sciences, 2015 In his paper [Ann. Math. (2) 70, 9--42 (1959; Zbl 0088.28505)] \textit{W. K. Hayman} proved that a transcendental meromorphic function \(f\) with finitely many zeros in \(\mathbb{C}\) assumes every finite non-zero value infinitely often. In this direction, the authors prove some results with new ideas.

Optimal parameters for fiber Bragg gratings for sensing applications: a spectral study
SN Applied Sciences, 2021 The spectral characteristics viz. reflectivity, bandwidth, and sidelobes’ intensity for uniform and apodized (Gaussian, hyperbolic tangent, apod1, sine, and raised sine) fiber Bragg gratings (FBGs) were studied as a function of grating length and index ...

A characterization of the sine function by functional inequalities [PDF]
Mathematical Inequalities & Applications, 2011 In the present paper we deal with the first generalization of Wilson’s difference f (x)g(y)− f ( x+ y 2 )2 + f ( x− y 2 )2 , assuming that its absolute value is majorized by some function in a single variable. Mathematics subject classification (2010): 39B62, 39B82.

Note on λ- pseudo bi-starlike and bi-convex functions related with sine functions [PDF]
Surveys in Mathematics and its ApplicationsIn this paper we introduce two new classes ℬΣλ(μ) of λ-pseudo bi-starlike functions and 𝒦ℬΣλ(μ) of λ-pseudo bi-convex functions. Also, we determine the bounds for |a2| and |a3| where a2, a3 are the initial Taylor coefficients of f∈ℬΣλ(μ) and f∈𝒦ℬΣλ(μ ...

On the Superstability Related with the Trigonometric Functional Equation
Advances in Difference Equations, 2009 We will investigate the superstability of the (hyperbolic) trigonometric functional equation from the following functional equations: , , , , which can be considered the mixed functional equations of the sine function and cosine function, of the ...

A new probabilistic model with applications to the wind speed energy data sets
Alexandria Engineering JournalSo far in the literature, the two-parameter Weibull distribution and its other extensions are frequently implemented to analyze the wind speed energy data sets. However, based on our study of the literature, there is no published work about analyzing the
