Welcome to the Institutional Repository of Vidyasagar University

Dspace@VU is the Open Access Institutional Repository of Vidyasagar University. Research outputs of VU - journal papers, conference papers, reports, theses, patents etc. - are uploaded/self-archived by VU Faculty members / Resarchers who do research on different specialized areas . Interested users can freely download and use documents as most of them are directly accessible and full-text downloadable. 'Request Copy' forms can be used for documents to which direct full-text download is restricted due to publisher embargo. "This repository is administrated by Central Library , Vidyasagar University".

Digitized administrative documents ,Articles of the journals published by the university and old question papers of Vidyasagar University as and when made available have been uploaded in this repository

Repository is indexed by Google, Google Scholar, OAIster, ROAR, OpenDOAR, BASE

"Academic departments are requested to submit to the University Library the list of on-going PhD theses and other research projects taken up by the respective departments with relevant details for uploading in this repository. This information will highlight the research activities in the University as a whole."

The Novel Concept of Roman Domination in Fuzzy Graph See

Suppose = , is a graph. A Roman dominating function (RDF) of is a function : → {0,1,2} such that every vertex for which = 0 has a neighbor with = 2. The weight of an RDF is = Σ ∈ . The Roman domination number (RDN) of a graph , denoted by ℘ , is the minimum weight of all possible RDFs. In this study, we define RDF on fuzzy graph (FG). Our purpose is to develop a notion of the RDF and also to present some basic definitions, notations, remarks, and p...

On the Exponential Diophantine Equation 27^x – 11^y = z^2 See

In this article, we study and establish the theorem of the exponential Diophantine equation 27^x -11^y = z^2 , which has exactly two solutions where x, y and z are non-negative integers using Catalan’s conjecture, modular arithmetic, factorial method and elementary mathematical concepts.

Almost Pseudo-Ricci Symmetric Mixed Generalized Quasi-Einstein Space-time See

In this paper, an almost pseudo-Ricci symmetric mixed generalized quasi-Einstein spacetime has been revealed where the nature of associated vector fields is observed.

A Survey on Interval-valued Fuzzy Graphs See

Interval-valued fuzzy graphs (IVFGs) belonging to the fuzzy graphs (FGs) family, have good capabilities when faced with problems that cannot be expressed by FGs. The notion of an IVFG is a new mathematical attitude to model the ambiguity and uncertainty in decision-making issues. IVFGs are well-articulated, useful and practical tools to manage the uncertainty preoccupied in all real-life difficulties where not sure facts, figures and explorations are explained. In this paper, the concept...

Certain Types of Vertices in m-Polar Fuzzy Graphs See

In this study, we explore the concept of m-polar fuzzy (mPF) detour g-eccentric nodes within m-polar fuzzy graphs (mPFGs). We delve into the idea of mPF detour g-interior nodes and mPF detour g-boundary nodes, examining their significance and properties. Additionally, we establish the relationship between mPF detour g-boundary vertices and mPF cut vertices.

A Study of Thermodynamic Heat Transfer and System Efficiency See

In this paper, we try to provide an overview of thermodynamics first and second laws, which mainly deal with the transfer of heat. We mainly focus on heat transfer devices and the efficiency of energy conversion. We discuss and construct different cycles, taking into consideration the conversion of any forms of energy under consideration, in particular heat, to work on a continuous basis, which is the fundamental objective of nuclear power plant owners. One needs to have a better underst...

General Solution of the Diophantine Equation M^x p + (M q + 1)^y= (lz)^2 See

In this article, I study and solve the exponential Diophantine equation M^x p + (M q + 1)^y= (lz)^2 where M p and M q are Mersenne primes, l is a prime number, and x, y and z are non-negative integers. Several illustrations are presented as well as cases where no solution of the given Diophantine equation is present.
