A simplified overview of certain relations among infinite series that arose in the context of fractional calculus
AbstractAn interesting infinite series relation was proven recently by applying a certain known generalization of the Riemann-Liouville and Erdélyi-Kober operators of fractional calculus. In our attempt to give a much simpler proof of this result, without using the generalized fractional calculus operator, we are led here to another class of infinite series relations. Some relevant connections with a number of known results are also indicated
Some multiple integral transformations involving the H-function of several variables
AbstractThe object of the present paper is to give two general multiple integral transformations of the H-function of several complex variables, which was defined and studied elsewhere by the authors (cf., e.g., [10], [11] and [12]). It is shown how the main formulas (1,8) and (1,14) below, involving Fox's H-function ([4], p, 408) and the Laguerre polynomials, respectively, are related to each other and, of course, to a number of results given recently in the literature (see [1] and [5] through [9]). Several possible applications of the operational techniques provided by these results (and their various special cases) when viewed as multidimensional integral transformations are also indicated briefly
Query Expansion Strategy based on Pseudo Relevance Feedback and Term Weight Scheme for Monolingual Retrieval
Query Expansion using Pseudo Relevance Feedback is a useful and a popular
technique for reformulating the query. In our proposed query expansion method,
we assume that relevant information can be found within a document near the
central idea. The document is normally divided into sections, paragraphs and
lines. The proposed method tries to extract keywords that are closer to the
central theme of the document. The expansion terms are obtained by
equi-frequency partition of the documents obtained from pseudo relevance
feedback and by using tf-idf scores. The idf factor is calculated for number of
partitions in documents. The group of words for query expansion is selected
using the following approaches: the highest score, average score and a group of
words that has maximum number of keywords. As each query behaved differently
for different methods, the effect of these methods in selecting the words for
query expansion is investigated. From this initial study, we extend the
experiment to develop a rule-based statistical model that automatically selects
the best group of words incorporating the tf-idf scoring and the 3 approaches
explained here, in the future. The experiments were performed on FIRE 2011

Construction of a new family of Fubini-type polynomials and its applications
This paper gives an overview of systematic and analytic approach of operational technique involves to study multi-variable special functions significant in both mathematical and applied framework and to introduce new families of special polynomials. Motivation of this paper is to construct a new class of generalized Fubini-type polynomials of the parametric kind via operational view point. The generating functions, differential equations, and other properties for these polynomials are established within the context of the monomiality principle. Using the generating functions, various interesting identities and relations related to the generalized Fubini-type polynomials are derived. Further, we obtain certain partial derivative formulas including the generalized Fubini-type polynomials. In addition, certain members belonging to the aforementioned general class of polynomials are considered. The numerical results to calculate the zeros and approximate solutions of these polynomials are given and their graphical representation are shown. © 2021, The Author(s)
