New Results and Matrix Representation for Daehee and Bernoulli Numbers and Polynomials
In this paper, we derive new matrix representation for Daehee numbers and
polynomials, the lambda-Daehee numbers and polynomials and the twisted Daehee
numbers and polynomials. This helps us to obtain simple and short proofs of
many previous results on Daehee numbers and polynomials. Moreover, we obtained
some new results for Daehee and Bernoulli numbers and polynomials
New Results on Higher-Order Daehee and Bernoulli Numbers and Polynomials
We derive new matrix representation for higher order Daehee numbers and
polynomials, the higher order lambda-Daehee numbers and polynomials and the
twisted lambda-Daehee numbers and polynomials of order k. This helps us to
obtain simple and short proofs of many previous results on higher order Daehee
numbers and polynomials. Moreover, we obtained recurrence relation, explicit
formulas and some new results for these numbers and polynomials. Furthermore,
we investigated the relation between these numbers and polynomials and Stirling
numbers, Norlund and Bernoulli numbers of higher order. The results of this
article gives a generalization of the results derived very recently by
El-Desouky and Mustafa [6]
Forecasting the Climate Change through the Distributions of Solar Radiation and Maximum Temperature
The climate change crisis is negatively affecting the world and is the focus of many researchers attention for its life-threatening economic and climate impact on Earth. Therefore, this study aims to estimate the joint distribution function (EFXY) of both daily solar radiation (S) and daily maximum temperature (T) along with the Markov property. In this study, three-parameter distributions have been utilized with S and T, which are generalized extreme value (GEV) and Weibull (W-3P), respectively. Each of these parameters and the joint distribution function ((, )) have been estimated. Four real data of S and T in Queensland, Australia during two consecutive years are applied. The method of maximum likelihood estimation (MLE) is applied on the proposed distributions of S and T to estimate their parameters, which was validated using Goodness-of-Fit tests. In addition, the logarithmic (LFXY) model and the multi-regression model (MFXY) for (, ) are obtained. The results have been compared and the EFXY and LFXY are found to be non-equivalently, while the EFXY and MFXY are equivalent and homogeneous, confirming the validity of the joint distribution function estimate with the least error. Thus, the climate change probabilities are more accurately predictable by knowing both X and Y or by knowing both () and () with minimal error
